杜比视界，HDR画面区别。

Technically, Dolby Vision allows for a maximum resolution of 8K up to 12-bit color depth, maximum peak brightness of 10,000 nits and a color gamut up to Rec. 2020.[13][14] However, Dolby Vision content or profiles can have a lower resolution (FHD or 4K), 10-bit color depth and a peak brightness of 1,000 nits.[citation needed] Current displays cannot reproduce the full Dolby Vision brightness and gamut capability.[citation needed] In 2018, Dolby Vision required content to be graded for at least 4,000 nits.[15] Today, Dolby requires at least 1,000 nits.[16] There are no brightness and color gamut capability requirements for consumer displays. When the consumer display has lower color volume than the mastering display, the content is adjusted to the consumer display capability based on the dynamic metadata.[citation needed] Dolby Vision is considered to be future-proof.[17]
