Samsung 2021 TV lineup: everything you need to knowĭoes Dolby Vision deliver better pictures?.Given its greater creative palette, and the drive towards delivering consumer TVs with ever greater brightness, it’s certainly tempting to see this Dolby Pulsar monitor as a glimpse of HDR to come. However, Dolby has also developed a reference ‘Pulsar’ monitor that provides an 800,000:1 contrast ratio, a peak brightness of 4000 nits, and the so-called P3 colour range used in digital cinema applications. The minimum specification for Dolby Vision mastering requires the use of reference monitors with a contrast ratio of 200,000:1, peak brightness of 1000 nits, colour range ‘approaching’ the Rec 2020 standard, and support for the SMPTE ST-2084 HDR format. On the content production side, Dolby Vision seems more focused on pushing HDR to its technical limits. Despite only using static metadata, HDR10 requires HDMI 2.0a compatibility. This single HDR/SDR workflow approach makes Dolby Vision a convenient tool for content creators and broadcasters to use.Īnother advantage of Dolby Vision is that the metadata is embedded into the video signal, meaning it can run across ‘legacy’ HDR connections as far back as version 1.4b. This means that a Dolby Vision-enabled Ultra HD Blu-ray can also play back in HDR10 on TVs that only support that format.ĭolby Vision allows content producers to have either one or two ‘layers’ of data one carrying just an HDR signal, the other carrying a standard dynamic range (SDR) signal. Nor does HDR10 carry the same facility for continually optimising the picture to the capabilities of the screen it’s showing on.ĭolby Vision is built on the same core as HDR10, which makes it relatively straightforward for content producers to create HDR10 and Dolby Vision masters together.
It can’t provide a display with updates on how each specific shot or scene should be shown. With HDR10 content, your HDR TV only receives static metadata relatively basic ‘global’ information on the content being shown that applies to the entire film or TV show.
Dolby Vision-capable TVs combine the scene-by-scene information received from the source with an awareness of their own capabilities in terms of brightness, contrast and colour performance. This metadata carries scene-by-scene instructions that a Dolby Vision-capable display can use to make sure it portrays the content as accurately as possible.
