Various people have been chatting about new 3D TV's lately. There's 3D movies at the theater like Avatar and they want to be able to watch 3D at home on their television. In this editorial were going to go over the basics on how 3D TV works! There has been plenty of rumors and reviews about 3d TVs and how it may control the television industry. One market research company projects the 3D HD TV industry to expand over 4 times in the next nine yrs. This means almost everybody may be viewing, movies, sports, etc on a television that seems to make the images jump off the screen. Before you get a 3D HDTV you should be aware of more about it. For example: Do you need a new blue-ray player to view 3D movies? YES. Is 3D more expensive? No not really. Can you watch 2D television (normal quality)? Yes you can switch back and forth from 2D to 3D. 3D TVs is basically stereo for your eyes. One left image one right. In fact 3D pictures and video is sometimes taking using right and left lenses that are slightly off set. How offset? Its as about as offset as a pair of human eyes. About seven centimeters or four inches. Its called stereopsis. The mind thinks its looking at a 3d object because its seeing 2 different pictures, from 2 different angles. The same 2 viewing angles as your eyes. It creates the illusion of depth. Currently most TV companies have found a way to project two different images on only 1 screen without making it blurred and it cost to much to have 2 different televisions. So they came up with two main ways to fool your brain into seeing focused 3D images on one screen. 3D TVs currently falls into two separate categories. 3D movies you watch with active shutter glasses and 3D HD TV you view with polarized glasses. This is how active shutter functions. The glasses are fueled by batteries and our linked to an emitter in your 3D TV. The emitter in your TV uses info-red signals that tells your lenses to either open or close. Like a window shutter. This is possible because of quick flashing right and left images on the screen. It happens over 100x a sec. Thats why its very difficult if not impossible to get plasma television or LED TVs into 3D. This is refered to as HZ. Also known as the refresh rate. So now were all aware about active shutter glasses, however theirs another way to view 3D TV. If you've seen Avatar or Alice in wonderland in the movie theater you were using polarized glasses, just like shutter glasses. Polarized lenses lets you see different slightly off-set images in each eye. Your mind is creating the false image that your seeing 3D, Movie theaters have 2 different projectors flashing both right and left images on the screen. It all works and syncs together because it allows your left eye to see only the left image and your right eye only to see the right image and also polarized lenses are not battery powered because there passive. Presently their is alot of 3D software out there like dvd's, but 3D TV's also give you a great picture even on non-3D things too. So if you're going to buy a tv. You may want to think of a new 3D TV. You'll get a great picture now and will be ready in the near future when more 3D content is available. 3D movies are actually filmed using two video cameras to simulate what we see with both of our eyes. Our brain automatically puts these two moving images to give that 3D look. What's tricky is making sure you have the right perspective for each eye. Different TV manufactures are using slightly different approaches. The greater part of 3D TV's use a special screen that displays two different versions of an image at the same time. It does this by switching video frames very quickly. The right eye and the left eye are shown 2 different pictures. If you're watching 3D television without the special glasses then the image is going to look very blurry. If you have seen a 3D movie in the theater your probably familiar with the 3D glasses. However the 3D glasses for televisions are completely different. There a lot more advance. These are wireless, battery powered, liquid crystal, shutter glasses. I know that may freighten you, but it's really not complicated. 3D TV's emmit out certain signals to balance the timing of the glasses. So either the left or the right image that darkens and blacks out the image in sync with what's on the TV screen. So your left and right eye see both the left and right version at the same time. Our brains are pre-programed for 3D, that's how the world looks to us everyday. Our brains translate what's on a 3D TV screen in the same fashion as everyday life. One frequently asked question is... Does the glasses create a flash? No. The images flash over 100 times a second. So our minds just fill in the blanks automatically. If you want a 3D TV at home here's what you'll need. First you'll need a TV that's designed for 3D kind of of like the Samsung UN55C7000. After that there are 2 options. There are 3D ready TV's. Those have the built in admitter that sends out the beam to control the glasses or there are 3D compatible TV's. With those you'll need to buy a differnt admitter box. You'll also need 3D glasses for everyone that's going to be viewing. You also want to be positive that the 3D glasses are able to be used with your 3D TV. The best and for sure way to get it right is to buy the same brand of 3D glasses as the 3D TV itself. You'll also need a 3D video signal. Now most 3D TV's will be able to convert 2D video (standard video) to 3D, but for 3D video that looks best. You'll want to see video already converted to 3D. You will also need HTMI cables. When it comes to the movie-theater you have two different light sources, two various projectors that put a polarizer on the front of each projector. 1 will be polarize for the left eye and one will be polarized for the right eye. So if there is eye-wear that have the same polarity as the right and left, then were ensured that the left image goes to the left eye and the right image goes to the right eye. So when you buy television, you only have 1 light source. So you'll have to make a right picture and a left picture in two different ways. We do this in a frame sequence kind of way. The television produces a right and a left image really fast. What we have to do though for it to synchronize with our eyes is we have to use a pair of glasses that is synchronize to the TV. So the television will tell the eye-wear... I am now showing the left image. So therefore the lens of the left side of the eye-wear will become transparent, When this happens the right lens will be going dark. So therefore the left image is being seen by the left eye. This is all done really quick and is all mixed together which is why you don't notice any quick flashing. There is nothing bad with plasma television or LCD HDTV in respects to 3D TVS. The major difference between the 2 is how they create light. LCD HDTV has to update its picture very quickly. The problem with a LCD is because LCD HDTV uses technology that functions as little gates that close and open to allow the back-light through. It may take sometime for those tiny LCD molecules to change their state, now this can cause make a problem where the left eye sees part of the right image and the right eye sees part of the left image. Now, as for plasma television. It makes frame sequential images. A left then a right. A plasma television starts with a pixel that produces its image, then erases it and then produces the next one. So when you produce a left, right, left, right image, Theirs a tiny chance of screwing it up, because it does one at a time. So is 3D TV right for you? Obviously its worth looking into. If you liked 3D movies in the Imax theater, then getting a 3D TV in the living room would be the right thing to do.Date: April-01-2012
If you want to learn about HD, Learning the difference between interlace and progressive is important. Interlace format is normally the standard format behind normal television image. 50% of the resolution is virtual, which means it doesn't exist. This works by splitting every frame into 2 fields. The first field is every other line of information. So, every even line of resolution is on the TV. Every odd line of resolution is black and not on the screen. The second field reverses that where ever even line is black & every odd line actually has all the data on the T.V.. When you combine those two fields you get one frame and they flash back & forth very quickly. What this means, is that any moment in time you don't have the full resolution available to you. You've only got 1/2 the resolution on the screen. The flash is so quick that the human eye cannot pick it up. What it does do is make something called interlace-artifacting. Interlace-artifacting is when you take something like a soccer ball and you kick it rapidly across the screen. What ends up happening is it smears and smudges, you get weird horizontial lines that break through the ball, because half the data is virtual & the set cannot keep up. The naked eye does have the ability to see these changes. It also makes it extremely difficult to put interlace info on a progressive screen. This is because the vast majority of the high definition monitors are progressive. Your plasma monitor is progressive; your LCD screens are progressive; Also DLP screens are progressive. The only thing that's left is CLT monitors. So whats progressive? Progressive HD video is where every single line of resolution is on the TV all the time. This means no virtual field, all of it is a full frame. That means when you kick that soccer ball across the ground. Both lines have information, as opposed to Interlace where its every other one. There is no interlace-artifacting that has smear on it, none of this. So the picture is pure & perfect every single time. Movie cinemas are mostly progressive. Progressive is the best way to get all of your content on the screen at the same time. They're two different resolutions in HD video, 1080 and 720. Interlace and progressive follow that, so 720p would be 720 progressive lines of resolution. In other words all of the information is there all of the time. 1080i would be 1080 virtual lines of resolution. So 540 actual lines of resolution. A lot of people think that 1080i is a normal above 720p, nevertheless because of that virtual information its not. The best high definition format is 1080p then 720p then 1080i. 1080p being 1080 progressive lines of resolution or all of the lines out there. HD Blue-Ray's can handle 1080p. Youtube is now 1080p combatable, but you cant broadcast 1080p, at least not today. The maximum broadcast lines of resolution you can go 1080 interlace lines or 720 progressive lines. If you have a choice, I highly recommend doing 720p prior to 1080i. Mainly if you have a plasma monitor, a DLP monitor or a LCD monitor, this is because your display technology isn't interlace its progressive. There is another important aspect to talk about and thats the "frame rate". If you want to be aware of the frame rate then its crutial that you understand the differences between interlace and progressive. Interlace is two fields make one frame. So they measure the frame rate by fields & not frames. So lets use 1080i vs. 1080p for example. You'll sometimes notice that 1080i/60. That means 1,080 interlace lines at 60 frames per second. So interlacing gets you every time. It gets you on interlacing artifacting & on frame rate. Because 1080i/60 is really only 1080p/30 and its got all that extra interlaced garbage that makes the picture look bad. So lets go over the genuine HD spectrum again. The best is 1080p then the 2nd best is 720p & then 1080i. Some folks may say. "so whats the deal with 480p"? Though 480 is not HD. That's considered enhanced defention. At the end of the day everyone has there own opinions as to the order they go in, but many can all agree that 1080p is the best as of today hands down.Date: March-18-2012
Understanding the difference between progressive video and interlace video is key to learning H.D.. Interlace video is what we've been using for many decades and is the de facto technology following standard definition. 50% of the resolution is virtual, which means it doesn't exist. The way that works is you split every frame into 2 fields. The first field is every other line of information. So, every even line of resolution is on the TV. Every odd line of resolution is black and not on the screen. The second field reverses that where ever even line is black & every odd line actually has all the data on the T.V.. When you bring together these two fields, you may get one frame. This means that in a few cases at certain periods of time you do not have access to full resolution. You get only half of the resolution on the screen. This flash is so fast that the brain just fills in the blanks. What it does do is create something called interlace-artifacting. Interlace-artifacting is when you take something like a soccer ball and you kick it quickly across the screen. The shows a visual "smear & smudge", you get odd lines that break through the ball, because the set cant keep up & even if it did, half the data is virtual. The naked eye does have the ability to see these changes. It also makes it really difficult to put interlace info on a progressive screen. Most high definition screens are progressive. Your plasma monitor is progressive; your LCD screens are progressive; Your DLP screens are progressive. The only thing that's left is CLT screens. So whats progressive? Opposed to what we talked about prior, Progressive H.D. is when all lines are on the TV at the same time. There is no virtual field, everything is a full frame. This means when you throw a football down the field. Both lines have data, as opposite to Interlace where its every other one. There is no interlace-artifacting that has smear to it, none of that. So the image is pure & perfect every single time. When you go watch a movie in the theatre, that's progressive. Progressive is the best way to get all of your content on the screen at the same time. There are 2 various resolutions in high definition video, 1080 and 720. Interlace and progressive follow that, this means that something like 720 would mean 720 lines of resolution. In other words all of the information is there all of the time. 1080 equals 1080 virtual lines of resolution. So 540 actual lines of resolution. Some folks think that 1080i is better than 720p, but because of this virtual info its not. Quality wise 1080i at the bottom then 720p & then 1080p the best. 1080p equals to all the lines being there as opposed to just 1/2. HD DVD blue-ray, they could be 1080p. You can download 1080p on the internet, but, you cant produce 1080p today. The most broadcast lines you can accomplish is 720p and 1080i. If you can choice, I highly advocate doing 720p prior to 1080i. Mainly if you have a plasma monitor, a DLP monitor or a LCD monitor, because your display technology isn't interlace its progressive. There is another important aspect to talk about and thats the "frame rate". Learning the frame rate requires again understanding the difference between interlace and progressive. Interlace is two fields make one frame. So they measure the frame rate by fields & not frames. For example lets take 1080p and 1080i. Every once in awhile you will see 1080/60. This equals to 1080 interlace lines at 60 frames/sec. So interlacing gets you every time. It gets you on interlacing artifacting and on frame rate. Because 1080i/60 is really only 1080p/30 and its got all that extra interlaced garbage that makes the image look bad. So lets go over the actual HD spectrum again. It starts at 1080i then 720p then at best at 1080p. Some inhabitants may say. "so whats the deal with 480p"? 480 Is not H.D.. That's considered enhanced defention. Every person has there own opinions about these High Defention technologies, but all can agree that 1080p is the winner.Date: January-08-2012
The Television family now has a couple of new recruits, along with LCD and Plasma. We now have LED back light TV. LED back light TVs which the industry is simple calling LED TVs. The debate of LCD TV vs Plasma TV is as old as the hills. back when LCD and Plasma were created one of the most popular discussions in the TV industry is Plasma vs LCD. In the past 5 years these 2 have been battling it out, you'd think there'd be a winner by now. We'll begin with the comparisons of the two technologies. Lets begin with plasma tv. Plasma has millions of gas cells that are combined to create an image. On the other hand LCD or liquid crystal display uses "glass sandwiches" of liquid crystal. This illustration is created by regulating the amount of electrical charge to each indivual crystal. Then the image is lit behind by a series of LED's or florescent tubes. These things are the differences between the 2 different types of TV. For example if a plasma cell is off Its not lit up meaning more blacks, A LCD pixel is still using electricity and lit even when the screen is dark. However LCD backlighting has gotten better over the years, plasma television has stayed one step ahead. Even with the largest sizes we've seen some excellent results from the best LCD TV 55 inch screens, but hands down plasma television is the better one. The disadvantadge, the motion sensor is the major one. there's a lag when LCD pixels turn on and off. Even the best LCD TV have a refresh rate of 5 milliseconds or less, but it can still lead to a lagging in motion effect. Plasma TV has the lexury of not having to worry about this, not to mention the black level issue. If you were to buy a plasma television. Theirs two facts that you should know. First Plasma TVs are not made in smaller sizes less then 42 inches. So only 42 inches or larger if going with a plasma television. Therefore there not ideal for small rooms like a kitchen. 2nd, Plasma TVs will reflect room light more so then other TVs. If you have a room with a lot of lamps and windows. Then you might want to go with a led TV. Plasma television will give you a bright in-depth picture. They also have a skinny design that allows them to be set on a stand or on a wall. Plasma televisions are known for there smooth motion, rich colors and impressive contrast levels. The three main advantages to having an LED TV were not going to give you a science lesson about the technology. LED TVs are known for having depth, color and energy efficiency. Comparing it to Plasma TVs and LCD TVs . LED TV's have darker blacks and whiter whites. This is also called ratio and you'll often see this listed as a feature on TV's. Basically the higher the ratio the better the contrast so the better the picture. secondly the slim and thin design of LED TVs is unbelievable. If you thought an LCD TV is thin. LCD TVs are usually twice as big as a LED. 3rd as they work differently from plasma and LCD televisions. You'll be able to go green because LED use a lot less electricity and will help you save money in the long run. And the final benefit to having a LED TV. You can watch it from nearly any angle and the color will be sharp and the color clear and deep. So how do you know if a plasma TV or LED TVs is right for you? If you want a cinema-like experience in a darkened or dim room. Then you'd probaly want to go with plasma television because of its true to life color and fluid motion. If you looking for a TV under 42 inches then LED TVs are right for you. They have brighter whites and deeper blacks, the cheaper one is plasma televisions.Date: October-25-2011
If you want to learn about HD, Learning the difference between interlace and progressive is important. Interlace video is what we've been watching for many years and is the fundamental technology following standard definition. Half of the resolution is virtual, which means it doesn't exist. The way this works is you split every frame into 2 fields. The first field is every other line of data. So, every even line of resolution is on the TV. Every odd line of resolution is black and not on the screen. The second field reverses that where ever even line is black and every odd line actually has all the information on the T.V.. When you bring together these two fields, you may get one frame. This means that in some cases at certain periods of time you do not have access to full resolution. You've only got half the resolution on the screen. The flash is so quick that the human eye cant pick it up.
It does something thats called interlace-artifacting. Interlace-artifacting is when you take something like a soccer ball and you kick it fast across the screen. What ends up happening is it smears and smudges, You also see horizontal tearing going through the ball, because the set cant keep up and even if it did, 50% of the info is virtual. The human-eye can perceive these changes. It also makes it really hard to put interlace content on a progressive screen. This is because the vast majority of HD monitors are progressive. Your plasma monitor is progressive; LCD screens are progressive; Also DLP screens are progressive. The only thing that's left is CLT screens.
So what is progressive? Progressive high definition video is where every single line of resolution is on the TV all the time. There is no virtual field, all of it is a full frame. That means when you kick that soccer ball across the ground. Both lines have information, as opposite to Interlace where its every other one. There is no interlace-artifacting that has smear to it, none of this. So the picture is pure and perfect every single time. When you go watch a movie in the cinema, that's progressive. Progressive is the best way to get all of your content on the screen at the same time.
720 and 1080 are on both sides of the H.D. coin. Interlace and progressive follow that, so 720p can be 720 progressive lines of resolution. This means its always there as opposed to every other one. 1080i would be 1080 virtual lines of resolution. So 540 actual lines of resolution. A lot of people assume that 1080i is a standard above 720p, however because of that virtual data its not. Quality wise 1080i at the bottom then 720p & then 1080p the best. 1080p equals to all the lines being there as opposed to just 1/2.
HD Blue-Ray's can handle 1080p. You can download 1080p on the internet, but, you cant produce 1080p today. The maximum broadcast lines of resolution you can go 1080 interlace lines or 720 progressive lines. If you have a choice, then my proposition to you would be 720p prior to 1080i. Especially if you have a plasma monitor, a DLP monitor or a LCD monitor, because your display technology isn't interlace its progressive.
There's 1 more number that comes into the formula & that's the frame rate. Understanding the frame rate requires again understanding the difference between progressive and interlace. Interlace is 2 fields make 1 frame. So this means that the measure not by frames, but by fields. i.e. lets take 1080p & 1080i. Every once in awhile you'll see 1080/60. That means 1,080 interlace lines at 60 frames per second. So interlacing gets you every time. It gets you on interlacing artifacting and on frame rate. Because 1080i/60 is really only 1080p/30 & its got all that extra interlaced non-sense that makes the picture look bad.
So lets overview the HD sphere once again. It starts at 1080i then 720p then at best at 1080p. Some inhabitants may say. "so whats the deal with 480p"? 480 Is not HD. Its considered to be called "enhanced definition. Finally everyone has there own opinions as to the order they go in, but all can agree that 1080p is the best.
So those are your high definition formats. Hopefully you'll now know which works best for your situation.

The TV family tree now has a couple of new recruits, as well as Plasma and LCD. We now have LED back light TV. The industry is calling these back lit led TVs as just simply LED TVs.
LED TVs has three main advantages without going into a physics lesson about the technology behind it. LED TVs are known for having depth, color and energy efficiency. Compare to LCD and plasma TV's. LED TV's have deeper blacks and whiter whites. You'll often notice this feature located on the TVs menu. Its called contrast ratio. To get a better viewing picture you'll need a higher ratio to get better contrast as a result it will give you a better picture. 2nd the slim and thin design of LED TVs is breath taking. If you think an LCD TV is thin. LED's are typically less then half the depth. 3rd, LED TVs function differently from Plasma and LCD TVs. They use a lot less electricity which will save you money and help you be more green. And the final benefit to having a LED TV. you can watch your LED TV from almost any angle in the room and unlike plasma and LCD the color wont be darker.
Plasma television will give you a bright in-depth picture. They also have a skinny design that allows them to be set on a stand or on a wall. Plasma televisions have a reputation of having rich colors, impressive contrast levels and rich motion.
If your considering a plasma television there's 2 things to keep in mind. First plasma's our not available in smaller screen sizes. Just 42 inches or bigger. So a cheap plasma TV is usually around $600 or less. Therefore there not ideal for small rooms like a kitchen. Second, some plasma television screens may reflect room lights. If you have a room with a lot of lamps and windows. Then you may want to turn them down and close the curtains.
So how do you know if a plasma TV or LED TVs is right for you? Well for a cinema like experence in a dark room. Then you'll like plasmas fluid motion and true to life colors. If you looking for a TV under forty-two inches then LED TVs are right for you. They have brighter whites and deeper blacks, the cheaper one is plasma televisions.
For awhile There has been a debate of Plasma TV vs LCD TV. Ever since Plasma and LCD were created one of the most popular debate in the television industry is Plasma vs LCD. In the past five years these 2 have been battling it out, you'd think there'd be a victor by now.
We'll begin with the comparisons of the two technologies. We'll begin with plasma television. Plasma has millions of gas particles that are brought together to create a picture. However LCD television uses liquid crystals to put together an image. This illustration is created by regulating the amount of electrical charge to each indivual crystal. Then the screen is lit behind by a series of LED's or florescent tubes. This is because the differences between the technologies. For example if a plasma cell is off its unlit meaning better blacks, while a LCD pixel is still lit from behind even when its displaying black. Though LCD backlighting has improved, plasma TV has had one step in front of LCD HDTV. Even with the largest sizes we've seen some excellent results from the best LCD TV 55 inch screens, but without debate plasma TV is still better. The disadvantadge, the motion sensor is the major one. It lags when LCD pixels are turned off and on. Even the best LCD TV have a refresh rate of 5 milliseconds or less, but it can still lead to a lagging in motion effect. This is something plasma TV doesn't have to worry about, not to mention the black level issue.
Plasma's are very good at creating a film like picture. Doesn't mean you have to go the whole way to get a movie theater experience. Currently 1080p has made an impact on plasma TV's and the number is growing. The only bad thing, Burn in effect This happens when a panel shows the same picture for a extensive period of time and the image is permanently burned in on the screen. For Plasma televisions this doesn't last forever and will eventually fade away. Finding a cheap plasma TV is not difficult, but you may want to consider the prices vs LCD.
Despite the current high definition buzz theirs still very little content available for 1080p. Especially when compared to the infinite amount of SD content like TV programs and DVD's. 1080p means 1920 by 1080 pixels and is the highest broadcast resolution there is. To buy a 1080p television now may give you some comfort. However you may not be getting the best picture. Its not all about the resolution.
Other features to look for would include 100 hertz. This in fact removes the awful jittery picture from movies and over-seas television shows. Another similar technology called 24P is also designed to make the most for HD disk.
Still confused? well don't be. You are the only person who can make the right choice as to buy tv. Best thing to do is to watch as many televisions as possible at once using the same footage. Try going to your nearest outlet store to do this. Then after choosing the tv you want to buy. Go on the net to Plasma God and search for the same make and model. 9 out of 10 times Plasma God is the cheapest.

Lots of people have been talking about 3D lately. There's 3D movies at the theater like Avatar and they want to be able to watch 3D at home on there TV's. In this article were going to cover the basics on how 3D TV works!
You've probably heard the rumors about 3D TV's and how it may dominate the television industry. Within the next 9 years one market research firm projects the 3D TV market is going to grow nearly 300 times. Meaning almost everybody may be watching, sports, movies, etc on a TV that seems to make the images leap off the screen.
Before you get a 3D TV you should know more about it. For example: Do you need a new blue-ray player to watch 3D movies? YES. Is 3D a lot more expensive? No not really. Can you watch 2D television (normal quality). Yes you can switch back and forth from 2D to 3D.
A 3D display on a 2D surface is basically stereo for your eyes. One left image one right. In fact 3D video and pictures is sometimes taking using right and left lenses that are slightly off set. How offset? Exactly off set as a pair of human eyes. About 7 centimeters or 4 inches. Its called stereopsis. The brain thinks its looking at a 3d object because its seeing 2 different pictures, from 2 different prospectives. The same 2 viewing angels as your eyes. It creates the illusion of depth. Right now TV companies can project those 2 pictures on to 1 screen at the same time without making them blurry and its to expensive to have 2 different TVs for each eye. So they came up with 2 main ways to trick your brain into seeing focused 3D pictures on 1 screen.
3D TVs currently falls into 2 different categories. 3D you watch with active shutter glasses and 3D TV you watch with polarized glasses.
Here's how active shutter works. The glasses are powered by batteries and our linked to an emitter tin your 3D television. The emitter sends radio or info-red signals to your glasses and tells each lens of the glasses to either open or close. Like a window shutter. This happens in-sync with fast flashing left or right images on the screen. This all happens over 100 times a second. This is why its nearly impossible to turn your LED TVs or a Plasma television into 3D. This refresh rate is also known as the HZ.
OK so you know about active shutter glasses, but that's not the only way to see 3D. If you've seen avatar or Alice in wonderland in the movie theater you were using polarized glasses. Like shutter glasses. Polarized lenses lets you see different slightly off-set images in each eye./ Tricking your brain into seeing 3D, but instead of flashing left and right pictures one at a time on the screen. Movie theaters project both left and right images at the same time with 2 different projectors. Its not blurry because the left lens only lets your left eye see only the left the left picture and the right lens only lets your eye see the right picture and remember polarized lens dont need to be battery powered or synchronized there passive.
Right now there is not a lot of 3D content available, but 3D TV's also give you an excellent picture with everything you watch even non 3D stuff too. So if you're shopping for a new TV you may want to consider a new 3D TV. Because you'll get a great picture now and will be ready in the near future when more 3D content is available.
3D movies are actually filmed using two cameras to simulate what we see with both of our eyes. Our brain combines these two perspectives and that creates the 3D effect. What's tricky is making sure you have the right perspective for each eye. Different TV manufactures are using slightly different approaches. Most 3D TV's use special screens that can display two different versions of an image at the same time. It does this by alternating video frames very quickly. So the left eye and the right eye are shown two different versions. If you're watching 3D TV without the special glasses then the image is going to look very blurry. If you seen a 3D movie in the theater your probably familiar with the 3D glasses. The 3D glasses for TV's are completely different. There a lot more advance. These are wireless, battery powered, liquid crystal, shutter glasses. It sounds complicated but its really not. The 3D TV sends out infer red signals to control the timing of the glasses.
So either the left or the right image darkens and blacks out the image in sync with what's on the TV screen. So your right and left eye see both the left and right version at the same time.
Our brains are wired for 3D, that's how the world looks to us everyday. Our brains interpret the two images from a 3D TV screen in the same way it does with our two eyes in everyday life. One commonly asked question is... Do the glasses create any flicker? The answer to that is no. The images flash over 100 times a second. So our brain just fills it in automatically.
If you want 3D TV at home here's what you'll need. First you'll need a TV that's designed for 3D kinda of like the Samsung UN55C7000. After that there are 2 options. There are 3D ready TV's. Those have the built in admitter that sends out the beam to control the glasses or there are 3D compatible TV's. With those you'll need to buy a separate admitter box. You'll also need 3D glasses for everyone that's going to be watching. You'll want to make sure the 3D glasses are compatible with the 3D TV. This usually means buying the glasses that are the same brand as the TV itself. You'll also need a 3D video signal. Now most 3D TV's will be able to convert 2D video to 3D, but for 3D video that looks best. You'll want to see video already converted to 3D. You will also need HTMI cables.
So is 3D TV good for you? Obviously its worth looking into. If you like the 3D movie theater experience in the living room then you may want to explore the opportunity of 3D TV.

So it's finally here, with the 3D televisions already on store shelves. Folks are getting excited, but there are still a lot of un-answered questions about 3D TV's, that need to be addressed and the obstacles you acquire when you try to scale down that 3D movie theater experience in your bedroom. Today we will put those concerns to rest and explain the many obstacles in respects to 3D TV.With all the thrill surrounding 3D HD TV's. There comes a lot of facts and rumors. In this post we'll provide the information that will clear some things up once and for all. First thing you will need 3D glasses if you want to watch 3D TV, however not to many individuals are tickled to death about this, but it's a minor price to pay for having a 3D movie theater in your bedroom. Plus lots of... if not all 3D televisions have the standard TV format (2D). 3D TV can be switched on and off at the user's will.
A great thing about 3D televisions is that some of your previous 2D collections can be watched in 3D. Currently there might not be very many 3D DVD collections out on store shelves, however you can bring new life to your old DVD or Blue Ray collection by converting them to 3D. Some 3D televisions like the Sony XBR52HX909 are going to have built in converters so you can watch 3D TV right out of the box.
Unfortunately if you want a taste of 3D HD television then your gonna have to get a brand new TV. Due to the fact the technology is so new. Finding an adapter to convert 2D to 3D is very un-likely. The reason being is that 3D TV requires a higher refresh rate around 240Hz, which is double what you find on LCD's currently on the market. Some 3D TV's use something called "active shutter technology". You'll only be paying a slightly higher price on the TV, however the glasses could cost you $50-$100 a pair. Other 3D TV's that use polarized film may be more expensive, but will offer cheaper 3D glasses.
3D TV has appeared and disappeared many times throughout history, I bet you remember the virtual boy? Because of this people are uncertain about the success of 3D anything. 3D TV has a lot of obstacles to face in the living room. One potential problem is ambient light reducing the 3D effect.
The biggest obstacle to the 3D appearance are those huge bulky looking 3D glasses. It seems as if no one is wanting to wear them. Some individuals actually complained of eye strain and head aches. The demo TV's set up in there dark corners at local stores seem alright. 3D TV has had very few experiences in the living room... obviously because of it being so new.
So with the pros and cons weighed out and the 3D HDTV experience being so new. It's hard to make a decision. It seems the 3D market is scouring for some potential prospector's. The only down side is the glasses. However keep in mind that normal 2D television can be watched at anytime where glasses aren't needed. So that problem is solved.
Which is better 3D Plasma or 3D LCD?
Their has been a lot of talk recently about 3D TVs. One significant subject is often over looked when you buy TV and that’s 3D on what? 3D plasma or 3D LCD? Many folks think theirs not a big difference? Well that's not the case.
3D Plasma television may actually be better. Why? Well, plasma television sales has gone down while LCD HDTV have gone up. Well Plasma television have 2 big advantages when it comes to 3D. Those advantages are contrast and speed.
But first,, contrast. The eye receives high-quality when theirs a big visual difference between black and white. its refereed to as a contrast ratio. Plasma's is almost usually bigger than LCD HDTV, why? When a plasma television is black it's off, when LCD HDTV is black its because of the little crystals are darkened and sometimes a little bit of light gets through from the black-light. Lets say that even if the LCD could go all dark like plasma. It wont be as fast. Plasma can switch to black around 60 times quicker than LCD. This means that sports and video games are much better.
As mentioned previously about Plasma prices. Plasma's have dropped compared to their high definition cousins like LED and LCD. Due to demand issues this naturally will bring the price down. i.e. a standard 42-inch LCD HDTV and a basic 42-inch plasma television is around $500 vs $750(standard) Comparing prices to Plasma God. Ironically its a win, win for plasma 3D vs LCD 3D, because it has a better picture quality and cost less.

Good exposure is one of the greatest kept secrets of good surgery. Most newly grads find it easier for there first procedure with a teacher alongside. So, when the pupil does a surgery for the 1st time, he/she is more comfortable with a student assistant who has less experience then there's, he finds the operation very difficult. Exposure and retraction in the 1st situation were planned & maintained by the teacher & unnoticed by the novice until, with your less experienced partner, he had to give the exposure for himself.
Most generally the retractor is the many of medical tools which the student is more familiar with, It's the last one he masters. It takes focus and good execution to get clear exposure. In order for the doctor to complete exposure when placing the packing sponges and retractors. Its a big mistake to lean an assistant a facet of an operation as crutial for exposure & then regard him as a poor assistant if he fails to obtain good exposure for you.
Some structures tend to creep into the field by gravity, This is why this should be your first consideration in the exposure of medical tools, elasticity or respiratory movements. When you stabilize a field that does not require repeated time-consuming readjustment of the exposure.
When you put a sponge on a slippery structure it then allows you to have retraction of a single unit. The friction of the coarse sponge fibers grabs slippery tissue, reducing the potential motion of the structures. Sponges are more inclined to stay in place if they are wrapped around structures in such a way that tissue cannot outflank the sponge. If the sponge can be positioned beneath & around adjoining sides of an area to be exposed, you may have a light edge of chance for sustained exposure as opposed to the structure being retracted is barely covered where its visibility.
There are 2 various resolutions in HD video, 720 and 1080. Progressive and interlace goes after that, this means that something like 720 would mean 720 lines of resolution. This means its always there as opposite to every other one. 1080 equals 1080 virtual lines of resolution. This is 1/2 of 1080. Which means 540 real lines. A lot of people assume that 1080i is a normal above 720p, however because of that virtual information its not. Quality wise 1080i at the bottom then 720p and then 1080p the best. 1080p being 1080 progressive lines of resolution or all of the lines out there.
HD DVD blue-ray, they could perform 1080p. Youtube is now 1080p combatable, However, you cant make 1080p today. The maximum broadcast lines of resolution you can go 1080 interlace lines or 720 progressive lines. If you can choice, I highly suggest doing 720p before 1080i. Especially if you have a plasma monitor, a DLP monitor or a LCD monitor, because your display technology is not interlace its progressive.
There's another important aspect to talk about and thats the "frame rate". Understanding the frame rate requires again understanding the difference between progressive and interlace. Interlace means 2 fields make one frame. So they measure the frame rate by fields & not frames. So lets use 1080i vs. 1080p for example. Every once in awhile you will see 1080/60. This equals to 1080 interlace lines at sixty frames a second. Interlacing may get you every time. It gets you on frame rate & on interlacing artifacting. 1080i/60 is actually only 1080/30 & it have a lot of additionol interlace garbage that goes along with it.
So lets overview the High Defention sphere once again. The best is 1080p then the 2nd best is 720p & then 1080i. Some people may say. "so whats the deal with 480p"? Though 480 is not HD. That's considered enhanced defention. Finally every person has there own opinions as to the order they go in, but several can all agree that 1080p is the best as of today hands down.
So those are your high definition formats. Hopefully you'll now know which works better for your situation.

There are two different resolutions in high definition video, 720 and 1080. Progressive and interlace goes after that, so 720p would be 720 progressive lines of resolution. In other words all of the data is there all of the time. 1080i would be 1080 virtual lines of resolution. So 540 actual lines of resolution. A lot of people think that 1080i is a standard above 720p, but because of that virtual information its not. its actually quality wise 1080i at the bottom then 720p and then 1080p the best. 1080p being 1080 progressive lines of resolution or all of the lines out there.
HD DVD an blue-ray, they could do 1080p. You can download 1080p on the internet, but you cannot broadcast 1080p, at least not today. The highest broadcast lines of resolution you can go 1080 interlace line or 720 progressive lines. If you can your choice I highly recommend doing 720p before 1080i. especially if you have a plasma monitor, a LCD monitor or a DLP monitor, because your display technology is not interlace its progressive.
There's one more number that comes into the formula and that's the frame rate. Understanding the frame rate requires again understanding the difference between progressive and interlace. Interlace is two fields make one frame. So they measure the frame rate by fields and not frames. So lets use 1080i vs. 1080p for example. You'll sometimes see 1080i/60. That means 1,080 interlace lines at 60 frames per second. So interlacing gets you every time. It gets you on interlacing artifacting and on frame rate. Because 1080i/60 is really only 1080p/30 and its got all that extra interlaced garbage that makes the image look bad.
So lets go over the actual HD spectrum again. It starts at 1080i then 720p then at best at 1080p. Some people may say. "well what about 480p"? 480 Is not high definition. That's considered enhanced detention. Ultimately everyone has there own options as to the order they go in, but many can all agree that 1080p is the best as of today hands down.
So those are your high definition formats. Hopefully you'll now know which works best for your situation

Understanding the difference between progressive video and interlace video is key to understanding high definition. Interlace video is what we’ve been using for many years and is the fundemtial technology behind standard definition. Half the resolution is gone it virtual, it doesn’t exist. The way that works is you split every frame into 2 fields. The first field is every other line of information. So, every even line of resolution is on the screen. And every odd line of resolution is not on the screen its black. The second field reverses that where ever even line is black and every odd line actual has all the information on the screen. When you combine those two fields you get one frame and they flash back and forth very quickly. What that means, is that any moment in time you don’t have the full resolution available to you. You’ve only got half the resolution on the screen. The flash is so quick that the human eye cannot pick it up.
What it does do is create something called interlace-artifacting. Interlace-artifacting is when you take something like a soccer ball and you kick it quickly across the screen. What ends up happening is it smears and smudges, you get weird lines that break through the ball, because half the information is virtual and the set cannot keep up. The human eye can perceive these changes. It also makes it extremely difficult to put interlace content on a progressive monitor. Most high definition monitor are progressive. Your plasma monitor is progressive; your lcd screens our progressive; Your DLP screens are progressive. The only thing that’s left is CLT monitors.
So what is progressive? Progressive HD video is where every single line of resolution is on the screen all the time. There is no virtual field, everything is a full frame. That means when you kick that soccer ball across the field. All of the data is there the whole time. There’s no weird smearing there’s no interlace-artifacting, none of that. So the picture is pure and perfect every single time. When you go watch a movie in the theatre, that’s progressive. Progressive is the best way to get all of your content on the screen at the same time.

1080p is terminology you hear a lot of these days related to high definition television. But what exactly does 1080p mean? And why is 1080p technology superior? 1080p has become an industry standard in the world of high definition. 1080p refers to resolution or more specifically it refers to pixels. 1080p means that the resolution of the picture is 1920 vertical columns and 1080 horizontal rows of pixels. The “P” stands for progressive. Progressive means that you’re able to see the entire frame and every last pixel all at once for the very best picture. In total there are 2,073,600 pixels all working together at the same time to create each frame of video. 1080p means full high definition video.
720p is also considered high definition, but with only 1,049,088 total pixels. 720p is not as high resolution as full blown HD 1080p. 1920x1080p is now currently the largest and best resolution offered. Full HD 1080p technology has also shortened the idea viewing distance, allowing for bigger TVs to be viewed in smaller rooms from a closer distance with less eye strain and pixilation. Being close makes the screen feel much bigger. Further adding to the engaging experience that is, full definition HD.
LG’s Full HD 1080p technology also displays all video of lesser resolution, like standard definition in 1080p resolution. So rather you’re watching digital cable or a standard DVD. You’ll always being viewing the end product in 1080p resolution.

For a while There has been popular discussion of Plasma TV, LED TVs, LCD TV. back when LCD and Plasma were born one of the most popular discussions in the television industry is Plasma vs LCD. The TV family now has a couple of new recruits, as well as Plasma and LCD. We now have LED back light TV. The industry is calling these back lit led TVs as just simply LED TVs. In the past 5 years these two have been battling it out, you'd think there'd be a winner by now.
We'll start with the differnces of the two technologies. Lets begin with plasma tv. Plasma television has hundreds of thousands of gas cells that are brought together to make a picture. However LCD TV uses liquid crystals to put together an image. This image is created by regulating the amount of electrical charge to each indivual crystal. Then the image is lit behind by a series of LED's or florescent tubes. These things are the differences between the 2 different types of TV. For example if a plasma cell is off Its not lit up meaning more blacks, A LCD pixel is still using electricity and lit even when the screen is black. Though LCD backlighting has got better, plasma TV has had one step in front of LCD HDTV. Even with the best LCD TV 55 inch screens we've been able to see some fantastic results for LCD HDTV, but hands down plasma television is the better one. The disadvantadge, the motion sensor is the major one. It lags when LCD pixels are turned off and on. Even the best LCD TV have a refresh rate of 5 milliseconds or less, but it can still lead to a lagging in motion effect. This is something plasma TV doesn't have to worry about, and of course there's a black level issue.
Plasma televisions our only 42 inches or more, this being because plasma is a gas, The better picture quality with plasma televisions is because the gases like to be further apart from each other. That's the simple description. This also helps with making the colors look more natural. So it will be a little darker. Plasma televisions also have better motion in its picture.
Plasma's are very good at reproducing film like quality. but this doesn't mean you have to go the whole 9 yards for a cinema experience. currently 1080p has be on hit plasma panels in a huge way but the number is growing. The only bad thing, Burn in effect Many of you might have seen the burn in effect at an arcade on an arcade game you can still see the words "game over" on a screen. However this doesn't mean it will last forever and will sooner or later fade away in a just a matter of weeks. Finding a cheap plasma is not difficult, but you may want to consider the prices vs LCD.
Plasma television will give you a bright detail picture. Plasma television has a slim design (not as slim as LED though) that allows you to put on a stand or hang on a wall. Plasma televisions have a reputation of having rich colors, impressive contrast levels and smooth motion.
If your considering a plasma television there's two things to keep in mind. First plasma's our not available in smaller screen sizes. Just 42 inches or bigger. So a cheap plasma TV is usually around $600 or less. Therefore there not ideal for small rooms like a kitchen. 2nd, Plasma TVs will show room light more so then other TVs. If you have a room with a lot of lamps and windows. Then you may want to turn them down and close the curtains.
With LCD HDTV which stands for Liquid Crystal Display. Its going to be a little bit more vibrant and is a little better in glare reduction.
Light-emitting diode also known as LED TVs is more like LCD on steroids. Nearly all LCD TVs are LED TVs. The only thing LED about it is the back-lighting. The LED back-lighting will make it more energy efficient and will make your whites whiter and your dark's blacker due to the contrast ratio. LED TVs are a little more vibrant and a little more bright then an LCD HDTV.
The three main things to having an LED TV without going into a physics lesson about the technology behind it. Its color, depth and energy efficiency. Comparing it to Plasma TVs and LCD TVs . LED TV's have darker and deeper blacks and whiter whites. You'll often notice this feature located on the TVs menu. Its called contrast ratio. To get a better picture you'll need a higher ratio to get better contrast as a result it will give you a better picture. 2nd LED TVs are really slim. LCD TVs cannot hold a candle to LED TVs in regards to its thinness. LED's are usually less then half the depth. 3rd, LED TVs work differently from Plasma and LCD TVs. They use a lot less energy which will save you money and help you be more green. And the final benefit to having a LED TV. You can watch it from nearly any angle and the color will be sharp and the color clear and deep...
So how do you choose between a LED TV or a plasma television? If you want a movie theater-like experience in a dim or darkened room. Then you'd probaly want to go with plasma television because of its true to life color and fluid motion. If you looking for a TV under forty-two inches then LED TVs are right for you. They have brighter whites and deeper blacks, but overall Plasma televsions are way cheaper in price.
Despite the current HD buzz theirs still very little content available for 1080p. Especially when compared to the infinite amount of SD content like television programs and DVD's. 1080p means 1920 by 1080 pixels and is the best high qualitiy resolution money can buy. To buy a 1080p TV now may give you some comfort. However you may not be getting the best picture. Theres more to it then the resolution when buying a television.
Other features to look for would include 100 hertz. This removes the jumpy picture from over-seas shows and old movies. This can also be called the refresh rate. Another similar technology called 24P is also designed to make the most for HD disk.
Still confused? You are the only person who can make the right choice as to buy a tv. Try and watch as many televisions viewing the same shows/movies as you can. Try going to your nearest outlet store to do this. After choosing the right tv for you. Go online to Plasma God and search for the exact same TV. 9 out of 10 times Plasma God is the cheapest.

The question isn't necessary which one has the better picture? The question really is whats better for your particular room and how much do they usually cost?
Plasma television is a gas so its gonna start at 42 inches and go further up, because the gas likes to be a little further apart which will give it a little better picture. Thats the simple explanation. What you'll see with plasma television is more realistic skin tones and kinda of a more natural color. So it will be a little darker. Plasma televisions also have better motion in its picture.
With LCD HDTV which stand for Liquid Crystal display. Its going to be a little bit more vibrant and is a little better in glare reduction.
LED TVS which stand for Light-emitting diode is kinda of an advancement of LCD. What a lot of people don't know is all LED TVs are LCD. The only thing LED about it is the back-lighting. The LED back-lighting will make it more energy efficient and will make your whites brighter and your dark's darker due to the contrast ratio. LED TVs are a little more vibrant and a little more bright then an LCD HDTV.
So which ones are better and which ones are more expensive? Well 3rd place would be plasma televisions being an older technology is the cheapest and unfortunately the worse of the 3 TVS, but that doesn't mean its a bad technology. Some people actually prefer the picture Plasma offers over LED TVs and LCD's. A cheap plasma tv bought brand new can be found online at plasma god for around $450.
2nd place would be an LCD HDTV and is the most popular in the HD world. Even the best LCD TV can be found online around $700 for 42 inches.
1st place would be..... LED TVs, they have all the benefits that LCD have plus the back-lighting is better and more green. Just an overall better picture. Just like everything in this world that is green it cost more (which is why green economics doesn't work, but that's another story). You can find 42-inch LED TVS online for around $950. Thats right over twice as much as a plasma television (its a new technology give it a break the price will go down in 2 years). So unfortunately the better TV's in this case our the more expensive ones. Which makes sense.

The TV family now has a couple of new members, as well as Plasma and LCD. We've now got LED back light TV. LED back light TVs' which the industry is simple calling LED TV's.
The 3 main advantages to having an LED TV without going into a physics lesson about the technology behind it. Is color, depth and energy efficiency. Compare to LCD and plasma TV's. LED TV's have darker blacks and brighter whites. This is also called contrast ratio and you'll often see this listed as a feature on TV's. Basically the higher the ratio the better the contrast so the better the picture. Secondly LED TV's are incredibly slim. If you thought an LCD TV is thin. LED's are usually typically less then half the depth. Thirdly as they work differently from plasma and LCD TV's. They use a lot less energy which will save you money and help you be greener. Their is a final benefit for having an LED TV. You can watch it from nearly any angle and the color will be sharp and the color clear and deep.
Plasma television will give you a bright detail picture. They also have a slim design that allows them to be set on a stand or on a wall. Plasma televisions are known for there smooth motion, rich colors and impressive contrast levels.
If your considering a plasma television there's 2 things to keep in mind. First plasma's our not available in smaller screen sizes. Just 42 inches or larger. So the cheap plasma TVs are usually around $600. There generally not ideal for small spaces like a kitchen. Second, some plasma television screens may reflect room lights. If you have a room with a lot of lamps and windows. Then you may want to turn them down and close the curtains..
So how do you know if a plasma television pr LED TVs is right for you? If you want a movie theater-like experience in a dim or darkened room. Then you'll appreciate plasmas fluid motion and true to life color. If you like slimer tv's less then 42 inches with brighter whites and darker blacks then LED is right for you.

For along time one of the most popular discussions in the TV industry is Plasma vs LCD. In the 5 years since both have been in the marketplace you’d think the answer would be clearly defined, but it’s a bit more complicated then that.
Let’s start with the differences of the two technologies. We’ll begin with plasma. Plasma has millions of gas cells that are combined to create a picture. On the other hand LCD or liquid crystal display uses what is “glass sandwiches” of liquid crystal. Images created by varying the amount of electrical charge applied to the crystals. Then the screen is lit behind by a series of LED’s or florescent tubes. This is because the difference between the technologies. For example if a plasma cell is off its unlit meaning better blacks, while a lcd pixel is still lit from behind when its displaying black. Though LCD backlighting has improved, plasma has stayed one step ahead. Even if the largest sizes we’ve seen some excellent results from 55 inch screens, but plasma is still arguably better. The down sides, the monition blower are the biggest one. There is a lag when LCD pixels turn on and off. Some models are down to 5 milliseconds but none-the-less it can still lead to a blur in motion. This is something plasma doesn’t have to worry about, and of course there’s a black level issue.
Plasma’s are very good a reproducing a film like picture. Deep blacks, a lack of pixel ghosting and a lot of screen sizes. Doesn’t mean you have to go the whole way to get a cinema experience. At the moment 1080p has still to hit plasma panels in a big way but the number is growing. The only down side, Burn in effect! This happens when a screen displays the same image for a long period of time and the image permanently burns in on a screen. However this doesn’t last forever and will eventually fade away in a matter of days. For our money though? Plasma may cost a little more, but is a superior technology.
Despite the current HD buzz theirs still very little content available for 1080p. Especially when compared to the infinite amount of SD content like TV programs and DVD’s. 1080p means 1920 by 1080 pixels and is the highest broadcast resolution there is. Though buying a 1080p screen TV now may give you some comfort. You may not be getting the best picture. Its not all about the resolution.
Other features to look for would include 100 hertz. This effectively removes the awful jittery picture from movies and over-seas TV shows. Another similar technology called 24P is also designed to make the most for HD disk.
Still confused? Well the only person who can make a decision about getting the right LCD or Plasma TV is you. Try and watch as many TV’s viewing the same footage as you can. Try going to your nearest local best buy, wal-mart or any outlet store where they have the same video displayed upon dozens of TVs. Then after choosing the one you want go online to Plasma God and search for the same make and model. 9 out of 10 times Plasma God is the cheapest.

Lots of people have been talking about 3D lately. There's 3D movies at the theater like Avatar and they want to be able to watch 3D at home on there TV's. In this article were going to cover the basics on how 3D TV works!
Right now there is not a lot of 3D content available, but 3D TV's also give you an excellent picture with everything you watch even non 3D stuff too. So if you're shopping for a new TV you may want to consider a new 3D TV. Because you'll get a great picture now and will be ready in the near future when more 3D content is available.
3D movies are actually filmed using two cameras to simulate what we see with both of our eyes. Our brain combines these two perspectives and that creates the 3D effect. What's tricky is making sure you have the right perspective for each eye. Different TV manufactures are using slightly different approaches. Most 3D TV's use special screens that can display two different versions of an image at the same time. It does this by alternating video frames very quickly. So the left eye and the right eye are shown two different versions. If you're watching 3D TV without the special glasses then the image is going to look very blurry. If you seen a 3D movie in the theater your probably familiar with the 3D glasses. The 3D glasses for TV's are completely different. There a lot more advance. These are wireless, battery powered, liquid crystal, shutter glasses. It sounds complicated but its really not. The 3D TV sends out infer red signals to control the timing of the glasses. So either the left or the right image darkens and blacks out the image in sync with what's on the TV screen. So your right and left eye see both the left and right version at the same time.
Our brains are wired for 3D, that's how the world looks to us everyday. Our brains interpret the two images from a 3D TV screen in the same way it does with our two eyes in everyday life. One commonly asked question is... Do the glasses create any flicker? The answer to that is no. The images flash over 100 times a second. So our brain just fills it in automatically.
If you want 3D TV at home here's what you'll need. First you'll need a TV that's designed for 3D kinda of like the Samsung UN55C7000. After that there are 2 options. There are 3D ready TV's. Those have the built in admitter that sends out the beam to control the glasses or there are 3D compatible TV's. With those you'll need to buy a separate admitter box. You'll also need 3D glasses for everyone that's going to be watching. You'll want to make sure the 3D glasses are compatible with the 3D TV. This usually means buying the glasses that are the same brand as the TV itself. You'll also need a 3D video signal. Now most 3D TV's will be able to convert 2D video to 3D, but for 3D video that looks best. You'll want to see video already converted to 3D. You will also need HTMI cables.
So is 3D TV good for you? Obviously its worth looking into. If you like the 3D movie theater experience in the living room then you may want to explore the opportunity of 3D TV.

So it's finally here, with the strong line of 3D televisions hitting store shelves as we speak. People are getting excited, however there still are a lot of un-answered questions about 3D TV's and the challenges you get when you try to scale down that 3D movie theater experience in your living room. In this article we will be discussing technologies that go into 3D TV's and answer some questions about 3D TV.
With all the buzz around 3D televisions There comes a lot of rumors and misconceptions. In this article we'll provide the information that will clear some things up once and for all. First off you will need 3D glasses if you want to watch 3D Television, however not to many people are thrilled about this, but it's a small price to pay for having 3D cinema in your living room. Plus many if not all 3D TV's have the standard TV format. 3D TV can be switched on and off at the user's will.
Another cool thing about 3D television is that there converters that turn your existing 2d media into 3D. Right now there might not be very many 3D DVD collections out there, but you can bring new life to your old DVD or Blue Ray collection by converting them to 3D. Some 3D TV's like the Sony XBR52HX909 are going to have built in converters so you can watch 3D TV right out of the box.
If you want to experience the full HD 3D TV you're going to have to buy a new Television. The hope of buying an adapter and installing it to convert your previous TV to 3D is UN-likely. That's because 3D TV requires a much higher refresh rate at about 240 Hz, which is double what you find on LCD's on store shelves. For some 3D televisions that use active shutter technologies. You'll only be paying a slightly higher price on TV, but the glasses may cost $50-$100 a pair. Other 3D TV's that use polarized film may be more expensive but will offer cheaper glasses.
3D television has appeared and disappeared many times throughout history, remember virtual boy? So naturally people are a bit skeptical of 3D television of being a success. It has a lot of challenges to over come in the living room. One potential problem is ambient light reducing the 3D effect.
The biggest challenges to the 3D effect are those big clunky looking 3D glasses. It seems as if no one is looking forward to wearing them. Quite a few people actually complained of headaches and eye strain experiences. While the demo TV's look legit. 3D TV has had very few experiences in the living room. This being because it's so new.
So with the pros and cons weighed out and the 3D Television experience being so new. It's hard to make a decision. It seems the industry is looking for pioneers to grasp the reigns of 3D television and brag to all the neighbors about how cool your new TV is. The only down side is the glasses. However keep in mind that normal 2D television can be watched at anytime where glasses aren't needed. So that problem is solved.
