Modern sink devices support more than 1 type of colorspace like 601, 709, BT2020 etc. This helps to switch based on content type which is to be displayed. The decision lies with compositors as to in which scenarios, a particular colorspace will be picked. This will be helpful mostly to switch to higher gamut colorspaces like BT2020 when the media content is encoded as BT2020. Thereby giving a good visual experience to users. The expectation from userspace is that it should parse the EDID and get supported colorspaces. Use this property and switch to the one supported. Kernel will not give the supported colorspaces since this is panel dependant and our curremt property infrastructure is not supporting it. Have tested this using xrandr by using below command: xrandr --output HDMI2 --set "Colorspace" "BT2020_rgb" Please provide comments on this current approach. This is just an RFC to get some feedback. Will refine the series based on inputs and feedback.
