How is 3D TV different from 3D in the theater?

Many viewers have experimented with 3D presentations such as IMAX 3D. Although the technologies may differ in some way - more American theaters use passive glasses, the main practical differences between the 3D TV and 3D in the home theater is the size of the screen and the distance you from it sits.

In the house of the images is usually much smaller, occupying a small percentage of the viewing fields of the spectators, is generally less exciting. With 2D you can create a more immersive home theater seated close to the screen, but 3D can become a problem. Panasonic recommends a distance of places of at least 3 times the screen height and distance - about 6.2 meters from a 50-inch - and warns that the seat next to you may increase the risk of eye strain and a sore head . One expert we spoke, Martin Banks, UC Berkeley, has confirmed that they are too close to a 3D display can increase the risk of side effects.

The small screen may also present other problems unique to 3D, as a relatively small area. We have also seen that the edge of the image, which is much more evident with small screens, can interfere with the display of 3D images in 2D far more disconcerting.

One advantage of 3D TVs at home and the theater is the user's control. Some 3D TVs allow you to control compatible 3D experience, in addition to adjusting the standard image. Samsung models, for example, allow you to adjust the axis "G", or the amount of 3D effect, taste, comfort, or to compensate for variations in distance between the eyes.
