Why does a DisplayPort-connected monitor to a PC have CTA-861 data blocks such as "Colorimetry" (with xvYCC, bt2020, and other modes checked + md0), "Audio formats", "Speaker setup" and "HDR Static Metadata". Isn't a VESA DisplayPort supposed to support all of these in a PlugnPlay fashion? Perhaps these are for connecting the monitor to a console I'm assuming? It makes no sense to have Colorimetry for example when I read that it's strictly an HDMI setting. Was curious about that.

CTA-861 data blocks are not specific to HDMI. DisplayPort supports colorimetry, audio, and HDR.

So on a true 8-bit monitor you'd recommend setting colorimetry to "Default RGB" or "sRGB"? Would they be supported? By default it only checkmarks the first two xvYCC and BT2020RGB, there is no checkmarks for the Default RGB or sRGB. Should I enable them and uncheck the others to force the monitor to run 8-bit RGB full?
