It is out of convergence. The yoke, knobs and magnets control where the three color beams land on the front of the picture tube. When they are out of alignment the results look similar to the 3D movie effect.
www.hometheater.about.com is the best place to look for information about 3D TV without glasses. They have a lot of information there concerning this matter.
Passive 3D TVs polarizing glasses similar to those at the movie theaters.
When you are using your TV in 2D mode like net surfing or watching content in 2D, then you don't need 3D glasses. When you watch 3D content then of course you have to wear 3D glasses.
Of course you can. There is a clipper-type of 3D glasses that you can wear over your prescription glasses. It is not expensive or hard to find. Just type in 3D Glasses Clip on the internet and you will see lots of results. If you don't want the clip type then there are also 3D prescription glasses. I know the LG sells passive glasses for their 3D TVs that you can use for their TVs, theaters, and also as polarized sunglasses. However, it won't work with any of the other active 3D TVs because active TVs are only designed to work on the manufactured brand.
There are two technologies in use with 3D television. Active 3D requires glasses that have batteries while passive models do not. Crosstalk in active glasses has been a problem but it depends on the make of glasses and television. For passive 3D, look at Sony, Visio, Toshibe or LG.
No, with all 3D televisions you do need the glasses. It's just like in the 3D films at theater. However some glasses are a lot more comfortable so you should try looking for those!
Some 3D television sets include the 3D glasses, but some do not. 3D glasses are necessary to get the full three dimensional effects that the television is capable of showing.
For any passive 3D television, the 3D glasses from movie theaters will work.
3D TV work its like a normal tv but you dont wear 3D glasses thats all you need to know :)
Currently, all 3D televisions need glasses but the latest one are now only a few grams in weight. Active glasses are almost as light as passive glasses so there is no need to put up with the reduced resolution of LG passive 3D just to get light glasses.
No. there is no way you can use LG 3D glasses on Samsung 3D TV, they use different technology.
No my friend you cannot have LG 3D TV glasses separately. To get the glasses you have to buy LG 3D TV with new FPR technology. In SG type 3D TV technology the 3D effect comes out from the glasses but in the case of FPR technology the 3D effect comes out from the TV.
