Sony is entering the next round of  3D TV wars by introducing its first 3D TVs. Sony launched three new 3D TV models coming out this summer: the LX900, HX900 and HX800. The flagship model (LX900) comes in 52 and 60-inch sizes. The HX900 (46 and 52-inch) model features the best LED backlight technology with anti-glare coating and Motionflow PRO 400 - running at 200Hz with partial black frames inserted to make 3D look sharper.

3D Glasses

These Sony 3D TV sets require viewers to wear Sony's battery powered "active" glasses, which offer a 120 degree viewing angle. The LX900 comes with a built-in infrared transmitter and two pairs of glasses while the transmitter and glasses are optional extras for the HX900 and HX800. Sony 3D glasses are said to work with any Sony 3D TV. There is an option to switch off the 3D, and just watch it like a normal television.

There is a definite minimum viewing distance, particularly for sport. If you stand within about three metres of the 50 inch screens, the soccer match is very difficult to focus on.
