How Can You Tell If That Display Is Ultra HD? Here’s the New, Expanded Definition Real Reviews July 5, 2014 Consumer Electronics views: 2575 Image Source: Samsung Building on the early definition of what constitutes an Ultra High-Definition (UHD) display that debuted in 2012, the Consumer Electronics Association (CEA) has listed more features every Ultra HD device should support to earn the tag. For those who came in late, Ultra High-Definition (UHD) Or Ultra HD are names for display technology – TVs, projectors or monitors – with a minimum display resolution of 3840×2160 pixels and an aspect ratio of at least 16:9. With UHD, viewing quality is far superior to what currently available full HD (1080p) devices support, and is comparable with what you see on movie theatre screens. So if you are a buyer who wants to know whether the TV, monitor or projector you are about to buy falls under the Ultra HD tag, look out for the following features (Source – CEA press release): Display Resolution: Has at least eight million active pixels, with at least 3840 horizontally and at least 2160 vertically. Aspect Ratio: Has a width to height ratio of the display’s native resolution of 16:9 or wider. Upconversion: Is capable of upscaling HD video (1080p) and displaying it at Ultra High-Definition resolution. Digital Input: Has one or more HDMI inputs supporting at least 3840×2160 native content resolution at 24p, 30p and 60p frames per second. At least one of the 3840×2160 HDMI inputs shall support HDCP revision 2.2 or equivalent content protection. Bit Depth: Has a minimum color bit depth of eight bits. The press release also informs that to make the identification process simpler for consumers, CEA is working with its member companies to develop a UHD logo that can be ‘voluntarily’ used by manufacturers. The new changes will take effect from September 14 this year. Read the detailed CEA Press release here.
