Unigraf collaborates with Dolby Vision™

What is Dolby Vision?

Dolby has worked closely with industry leaders over the last 50 years to make the stories and experiences as engaging as possible—first with noise reduction, then 5.1 surround and 7.1 surround, and now with Dolby Vision™. Dolby Vision™ transforms the way you experience movies, TV shows, and games with incredible brightness, contrast, and color that bring entertainment to life before your eyes. By fully leverag-ing the maximum potential of new cinema projection technology and new TVs’ display capabilities, Dolby Vision delivers high-dynamic-range (HDR) and wide-color-gamut content. The result is a refined, lifelike image that will make you forget you are looking at a screen.

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)
