      UHD Alliance reveals its specs for 'premium' 4K TVs

      UHD Alliance reveals its specs for 'premium' 4K TVs

      Last year a number of TV manufacturers, Hollywood studios and other content companies got together so they could avoid ruining the home experience of 4K. A battle over competing standards and formats has made a mess of tech like Blu-ray/HD DVD and the rollout of 3D, but this industry consortium is committed to making sure that doesn't happen with Ultra HD. As Fox exec Mike Dunn put it during a panel discussion, "Unless you have a standards group that puts the glue for the industry together, it's not seamless for the consumer." Tonight the group showed off the logo and specs (above) that you should probably look for if you consider buying a high-end Ultra HD television.

      Update: Samsung says its entire line of 2016 SUHD TVs has been tagged with the UHD Premium certification.

      Any device or service with that sticker will have to meet certain minimum specs (resolution, color and bit depth, mostly, while TVs need to hit a specific combo of peak brightness and black leve) to qualify, and should be able to show you the best things Ultra HD Blu-ray, 4K streams from Netflix and Amazon, or 4K broadcasts can offer.

      That doesn't necessarily mean that devices without it won't be up to snuff (Vizio is notably missing from the list, but it is using Dolby's HDR tech, and Dolby is on the list). Still, nearly all of the industry's heavyweights are on board, and it will be interesting to see how many of the new-for-2016 products unveiled tomorrow hit the mark. LG quickly announced that its 2016 OLED 4K lineup "exceeds" the specification, and we'll see what else it has in store tomorrow morning during its press conference.

      Quite a number of reports that no TV on sale at the moment is truly worthy of this sticker.
      But many announcements at CES from the TV the manufacturers that their 2016 ranges will be.
      Interesting to hear at the press conference that Sky were named as a major player in this along with Amazon, Netflix. Samsung, DirectTV, Dolby, LG, Panasonic and the major TV studios.

      The specs released are below;

      Display Reproduction: More than 90% of P3 colors
      High Dynamic Range
      SMPTE ST2084 EOTF
      A combination of peak brightness and black level either:
      - More than 1000 nits peak brightness and less than 0.05 nits black level
      or
      - More than 540 nits peak brightness and less than 0.0005 nits black level

      Distribution
      Image Resolution: 3840x2160
