At the moment DF lets you choose color depth but there is probably close to zero situations where you want anything other than 32-bit. Instead I propose that this option is replaced by output bit depth (8-bit, 10-bit, 12-bit etc) and output color format (RGB, 4:4:4, 4:2:2, 4:2:0 etc) or these options are added to go with it. A HDR toggle would also be nice.

My use case for this feature would be to be able to switch between 10-bit/100 Hz/HDR and 8-bit/120 Hz/SDR using a shortcut key because nothing else supports this kind of thing to my knowledge. A lot of displays have these kinds of limitations if you want to use HDR so you end up having to toggle these things from say Nvidia Control Panel.
