4K Ultra HD

4K Ultra HD delivers more than four times the resolution of HDTV, which provides much greater details and a more immersive viewing experience.  At the 2014 International CES, nearly two dozen 4K compatible televisions and projectors were introduced by more than a dozen companies, with most ranging in size from 55 to 110 inches diagonally. In addition to displaying native 4K content, virtually all of these sets can also upscale 1080p entertainment; 3D HD content; and the latest connected streaming services.  Additionally, many of these sets will be able to support other potential applications in the future, including  auto stereoscopic (glassless) 3D;  2nd screen viewing, 4x2K HD images; and multiplayer gaming,

The Consumer Electronics Association (CEA) 4K Working Group initially stated that 4K Ultra HD certified models had to meet only three three basic requirements: the ability to reproduce 3840h x 2160v picture resolution (or higher); the capability to display a 16 x 9 wide screen image; plus a dedicated digital input that  can support native 4K content. Recently this definition was expanded to support high frame rate content (at up to 60 fps) and the CEA is also considering future  enhancements to address High Dynamic Range and Wide Color Gamut content as well.

To help promote this new concept, the CEA recently issued a 4K Ultra HD logo mark.  Properly implemented, this should help to minimize consumer confusion and position 4K Ultra HD performance as far beyond the current HDTV standard.
