Ten-bit video can represent more code values per colour component than 8-bit video. That can help preserve smooth gradients, but the source, encoding, display and processing chain still matter. Ten-bit also creates a compatibility requirement that some older decoding paths do not meet.
Understand what the number counts
Eight bits provide 256 possible code values per component; ten bits provide 1024. These values are not the same as resolution or the number of pixels. They describe how finely a component can be represented before further colour processing, rather than guaranteeing a particular colour gamut or brightness.
Watch a revealing scene
A blue sky, dim wall or foggy landscape can reveal abrupt bands between tones. However, banding can originate in the source or compression and may remain in a 10-bit file. Increasing a television’s colour control cannot restore missing gradations and can make skin tones look unnatural.
Check the complete path
A player must decode the format, the output must carry a compatible signal and the display must handle it sensibly. If a 10-bit stream shows a black screen while an 8-bit version works, investigate decoding and output support. Do not assume the subscription has failed simply because the audio continues.
