New TVs from LG and Philips have a feature that is called Dual Play. What is this? With Dual Play can you play video games at one TV with 2 persons and every person can see his own picture. All what you need is a TV with the feature from LG or Philips, a game console (Playstation 3, Xbox 360, Nintendo Wii U) and a video game that has a Splitscreen mode. For example: Gran Turismo 5, Gears of War, Killzone.
A good feature for gamers but the resolution will be cut and everyone has only the half of the original resolution. So the graphic is not very good anymore. But anyway a nice feature and maybe in the future it will be improved.
