It’s becoming increasingly difficult to buy a new 1080p TV as 4K resolution has become the norm, but now we’re getting an official definition and logo for what comes next: 8K Ultra High Definition displays.  The  Consumer Technology Association (CTA) has revealed what the requirements are for a television to claim it’s officially 8K. The definition is split down into four key areas covering display resolution, digital inputs, up-conversion, and bit depth.    The display resolution must have 33 million+ active pixels and be at least 7,680-by-4,320 with a 16:9 viewable window. All pixels must be individually addressable and demonstrate the full color range the display advertises as having.
