Is Your Ultra HD TV REALLY an Ultra HD TV?

By: Adrienne Maxwell, July 21, 2014, Home Theater Review

Just because your TV has a 3,840 x 2,160 resolution does not officially make it an Ultra HD TV, at least not according to the Consumer Electronics Association, which recently updated and expanded its list of core characteristics that a display device needs in order to be considered a true Ultra HD display. Here’s the rundown of those core characteristics:

1. Display Resolution: Has at least eight million active pixels, with at least 3,840 pixels horizontally and at least 2,160 pixels vertically.
2. Aspect Ratio: Has a width-to-height ratio of the display’s native resolution of 16:9 or wider.
3. Upconversion: Is capable of upscaling HD video and displaying it at Ultra High-Definition resolution.
4. Digital Input: Has one or more HDMI inputs supporting at least a 3,840 x 2,160 native content resolution at 24p, 30p, and 60p frames per second. At least one of the 3,840 x 2,160 HDMI inputs shall support HDCP revision 2.2 or equivalent content protection.
5. Colorimetry: Processes 2160p video inputs encoded according to ITU-R BT.709 color space and may support wider colorimetry standards.
6. Bit Depth: Has a minimum color bit depth of eight bits.

These core characteristics build upon the first-generation UHD characteristics released by the CEA back inOctober 2012, which required only three elements: 1) a display resolution of at least eight million active pixels, with at least 3,840 horizontally and at least 2,160 vertically; 2) an aspect ratio with width to height of at least 16:9; and 3) at least one digital input capable of carrying and presenting native 4K format video from this input at a full 3,840 x 2,160 resolution without relying solely on upconverting.
