The new VIZIO CinemaWide 50 and 58 inches 3D TV set has -as its name implies- an aspect ratio of 21:9 but it also offers 120 Hz, 1,000,000:1 contrast ratio, Full HD3D, plus wired and wireless Internet connectivity. It uses passive glasses technology for 3D, so 3D glasses at 2$ apiece are OK.
The large format means you can put a full HD (3D or not) movie and screen along with EPG and other info (i.e. Facebook) on the side.... Resolution is 2560x1080 pixels so there is a 640 pixels zone on the left of the 16:9 image for additional stuff.
