SDR ( Standard Dynamic Range ) displays ca n’t depict arrant Elwyn Brooks White and thick blacks . HDR ( High Dynamic Range)was created to improve picture quality by delivering greater contrast for a more salient and natural photo . HDR10 is the received HDR format that all devices must support .
Dolby Vision is an advanced HDR format that bestow a layer of active metadata on top of the HDR10 signaling .

Dolby Vision vs HDR10

With HDR10 , the metadata is static . It sets the luminance values ( i.e. , brightness ) for the entire runtime . So , if you ’re watching a TV show or pic , theblack degree , and highlights ( the brightest part of the double ) , stay the same throughout .
The problem with static metadata is that if a display ca n’t show the highlight or black levels as intend , then you may have issues with blacks being oppress ( losing detail ) or looking go up ( lack depth ) . The bright parts of the prototype can be affected by clipping ( departure of detail ) .
Dolby Vision practice what ’s called tone mapping to manage this trouble , adjusting the colours , brightness , and black tier to meet a exhibit . HDR10 content can be tone mapped , but this is ordinarily done by the tv set itself , and not every blade note maps in the same way which take to conflict in the image .
Dolby Vision masters of movies are done at 12 - bite color depth , rather than HDR10 ’s 10 - bit . 12 - bit profoundness can show a broad grasp of colours , as well as more nuance of brightness and contrast .
Also , peak brightness with Dolby Vision can go up to 10,000 nits while HDR10 is 1000 nit . Most Dolby Vision masters target 4000 nit although there are outlier , such as Mad Max : Fury Road , which was control at 10,000 nits .
