The Consumer Electronics Association (CEA) Oct. 18 put a name to the next generation of home displays, putting the Ultra HD tag on giant screens with more than eight million pixels of resolution, four times the resolution of today’s widely available HDTVs. To earn the Ultra HD designation, which requires resolution of at least eight million active pixels (minimum 3,840x2,160), displays must have an aspect ratio of at least 16x9 and must have a digital input capable of carrying native 4K video, instead of relying solely on up-converting.

Sony is grabbing some of that same spotlight, debuting its first 4K TV, the 84-inch XBR-84X900
