Dolby Vision
4K televisions have “more pixels” and newer standards for UHD TV also include high frame rates, but these standards don’t make each pixel able to better represent the full range of brightness we see in reality. Dolby Vision™ is the Dolby Laboratories solution to meet this challenge. The current TV and Blu-ray standards limit maximum brightness to 100 nits and minimum brightness to 0.117 nits, while also limiting the range of colours that can be displayed. Dolby Vision™ colour depth allows up to 10,000-nit maximum brightness. (Dolby 2016)
