My friend keeps telling me to buy a 3D TV with Cinema 3D TV. I've checked online and asked some people at Walmart and they have no idea what that is. Can you help me out?

Cinema 3D is the name of LG's passive 3D technology. It uses polarized lenses, which means the glasses are cheaper and lighter. I can't tell you if it's really any better than anyone else's.

Cinema 3D TV is a Full HD 3D TV that uses the same technology as the cinema. Passive 3D TV is the technological term. Cinema 3D TVs are flicker-free and crosstalk-free 3D TV which minimize eyestrain and headaches. Their 3D glasses are also battery-free and lightweight therefore very comfortable and affordable compared to active 3D type glasses. In fact, the price of Cinema 3D TV glasses are up to 10 times cheaper than active types.

There is no crosstalk free passive technology. The new circular polirizers get close, but there is always crosstalk. Active shutter can get closer, but unless you have glasses that can completely block out light, even they cannot prevent it.

The crosstalk which also known as ghosting means doubling image of 3D. The only difference between crosstalk and ghosting is that crosstalk can be measured but ghosting can’t be because it’s how the people feel. I'll correct my words up there. Waldojim, as you said, there is no crosstalk free 3D yet, but the crosstalk is more common for the active 3D technology, not the passive. The crosstalk happens at rate of 120hz or less and the separated images are more noticeable in most of Samsung, Sony, and Panasonic TVs that use active shutter. Many passive 3D TVs exceed 400hz, and a passive 3D TV from LG has minimum rate of 200hz when the Samsung has minimum rate of 60hz, and it is so obvious that you can notice much less crosstalk on those LG passive TVs.

It's all marketing, man. These companies are just inventing new names for the same technology to persuade people to buy their product. It's really that simple.

Yes and no. There's a lot of hype and marketing, of course. And the names of the "new" technologies are devised by the Marketing Departments. OTOH, sometimes one company does a better job at something than another.

Corsstalk and ghosting are not the same thing at all. And no, a higher frequency sub-frame rate will not fix this issue. Cross talk is essentially 'bleeding' of an image. It is caused when an image is received to the right or left that isn't supposed to be seen by that side. This is most common on high contrast material and has NO RESOLUTION.

To a small degree, active shutter is an answer, as it is supposed to block the image from the other eye entirely. In reality, most glasses only have a 400-500: Contrast ratio, and cannot fully block the image not intended for that eye.

I would recommend the Cinema 3D TV. People have said it before but basically, the 3D glasses are battery free which means no need for recharging! Also, this makes your glasses so much lighter! If you buy Cinema 3D TV, you get four pairs for free and can easily buy more to share with your friends. It's so easy to impress guests with this TV!
I've realized that Cinema 3D TV makes images brighter than other TVs and it's also flicker free so you won't get headaches and such. Also, you can watch the 3D effect from anywhere, since your glasses don't contain any liquids or batteries... if you move from your upright position with other brands, the image is broken, see..

Oh! And another great feature is the 2D to 3D conversion! this is so amazing! you can watch any movie, drama or show in 3d!! It's so easy to switch and the effect is satisfactory!

hope this helps!

Personally, I don't see the point of this--except maybe as a technical experiment. If a movie or TV show is worth my time, then it's worth seeing the way it was meant to be seen.

Adding 3D to something shot flat is bad enough. But to have it added by an algorithm instead of a human being is worse; you're handing creative control over to a machine.

Yeah, You should get one. I have one and 3D is fantastic.
It has wide viewing angle so we can watch 3D movie freely.

I prefer passive to active 3D now with LGs new interlacing technology you get the same 3 million pixels do both you eyes same as active sets but at a better refresh rate and and with nice comfortable glasses.

I am a mild fom of epilepsy and my doctor said I should be careful when choosing a 3D TV.
Any type of flashing/blinking can be dangerous.
Are there 3D TVs that do not have these effects?
When I say flashing/blinking, I do not meen like sudden explosions or things of that nature but more of a continous/constant nature.

You should definitely not get an active 3D set. I suspect LG's passive sets would be okay. They do some weird stuff to display both images, but I don't think it would be any worse than the interlacing you get with standard-def TVs or with 1080i broadcasts.

You are epilepsy? Joking aside please be careful around active sets they come with warnings for a reason and people have had seizures because of them. So ask If the glasses have batteries if they do don't watch or save your self a lot of trouble and get an LG.

Hi, I don't bother as I'm not buying one, whatever the name. Doctors say that watching 3D regularly is damaging not only to your eyes but generally makes you feel bad. More, children under six shouldn't watch it at all as they're growing and are going to have problems with vision as adults. I say 3D TV is one big misfire.


As to epilepsy, you should avoid stroboscopic light in general, e.g. techno parties. And there was, years ago, this cartoon that caused fits even with healthy people (stroboscopic effects).

Owning a 3D TV doesn't necessarily mean that you regularly watch TV that way. If I owned a 3D TV, and I have no plans to buy one at the moment, I'd only watch an occasional 3D movie that way. Most of the time, I'd watch 2D, because most of what I want to watch was made in 2D.

Agreed. I do own a 3d tv, and 99% of the content watched on it is 2d. That said, neither my wife nor I have ever experienced the side effects that people continuously complain about with active 3d. This may be a result of using DLP, but it hard to say for certain.

I have a passive 3D one because the idea of paying for all those glasses for sporting events made me crazy, also the first couple TVs I tried active on it could see extra cross talk and flicker for sure. These were expensive TVs also.

I never tried a DLP in person though.

With Oled right around the corner I can't imagine looking at one now though.

You do realize that OLED is going to be extremely expensive for the foreseeable future? Also, no one has had a chance to review a real OLED HDTV, so we can't say for sure if it will be as good as the hype suggests.
