Wow, install that on an exterior wall of your house, the radiant heat might cause issues otherwise. Heck, install it AS an exterior wall of your house, big as that sucker is.
TVs are quickly out-pacing the resolution of the video images they are displaying. 4096x2160? Clearly its intended as a display for businesses or something.
I remember my uncle buying a big 64-inch rear-projection TV. The thing was enormous and had a really good picture, but only supported Component video, no HDMI (nor did it include a digital TV receiver). Since hi-def blu-ray requires HDMI, the thing was basically just an expensive waste (though he was able to find a hi-def digital TV receiver that had component output). My point is, by the time this TV's specs can be realized, it will be real old and probably won't have the proper inputs to work properly.
