I'm still trying to wrap my head around how this works, I guess. If I am viewing a JPEG that is only 8 bit color (per channel), how does a 10 bit monitor make that any better without having a 10 bits per channel image source?
Or what if I'm in Photoshop in 32 bits per channel mode, doing some HDR work... does this 10 bit monitor mean I'm seeing slightly better colors (more dynamic range) than my old 8 bit monitor?
- brotchie 13y agoI'd assume the JPEG can have some embedded colour profile. This profile specifies a transform between the JPEG's 24bit colour space into the monitor's 30bit colour space. For example, consider two JPEGs with embedded colour profiles. "Red" (255,0,0) in one image will map to some "Reddish" 30 bit value, while (255,0,0) in the other will map to a slightly different 30 bit value.

This allows the display controller to apply gamma, contrast, and brightness curves to the incoming data without sacrificing any color resolution. When you make the same adjustments on your PC, the GPU has to dither the result back to 8-bit for transmission.
