Hi, I am using a Acer Aspire 5 A515-52G-77EK, when i look at the color bit depth, its only 6-bit instead of 8-bit. I have the latest updated graphics driver for Intel UHD Graphics 620 (25.20.100.6577)

Any ideas why? or what drivers i need to get 8-bit color depth?

    Good Morning automaton !

    That is normal. It means that you have an SDR (Standard Dynamic Range) and not HDR (High Dynamic Range) display. SDRs have a 6-bit color depth (i.e. bits used per color) instead of 8 or 10 bits used per color in HDR displays.

    This is different from the desktop color depth with can be 16, 24, or 32 bits and covers not just a single color but the whole color spectrum the computer can display.

    Hi, MaClane!
    Could you please explain why are you talking about any kind of dynamic range? DR is about highlighting the matrix, but bits of color depth are about color gamut. Monitor can have no any kind of extended dynamic range, but can have 8, 10 or even 12 bith per color channel.
