Without further knowledge if YCbCr 4:2:0 is supported outside of HDMI, there is no reason to use RGB when the display reports drm_mode_is_420_only() even on a non HDMI connection. This patch also moves both checks in the same if-case. This eliminates an extra else-if-case.

While "max bpc" can be used to change the color depth, there was no way to check which one actually got used. While in theory the driver chooses the best/highest color depth within the max bpc setting a user might not be fully aware what his hardware is or isn't capable off. This is meant as a quick way to double check the setup. In the future, automatic color calibration for screens might also depend on this information being available.

There was no way to check which color format got actually used on a given monitor. To surely predict this, one must know the exact capabilities of the monitor, the GPU, and the connection used and what the default behaviour of the used driver is (e.g. amdgpu prefers YCbCr 4:4:4 while i915 prefers RGB). This property helps eliminating the guessing on this point. In the future, automatic color calibration for screens might also depend on this information being available.

There was no way to check which color range got actually used on a given monitor. To surely predict this, one must know the exact capabilities of the monitor and what the default behaviour of the used driver is. This property helps eliminating the guessing at this point. In the future, automatic color calibration for screens might also depend on this information being available.

Possible options are: - auto (default/current behaviour) - rgb - ycbcr444 - ycbcr422 (not supported by both amdgpu and i915) - ycbcr420 In theory the auto option should choose the best available option for the current setup, but because of bad internal conversion some monitors look better with rgb and some with ycbcr444. Also, because of bad shielded connectors and/or cables, it might be preferable to use the less bandwidth heavy ycbcr422 and ycbcr420 formats for a signal that is less deceptible to interference. In the future, automatic color calibration for screens might also depend on this option being available.

Userspace can use this property to tell the graphic driver to use full or limited color range for a given connector, overwriting the default behaviour/automatic detection. Possible options are: - Automatic (default/current behaviour) - Full - Limited 16:235 In theory the driver should be able to automatically detect the monitors capabilities, but because of flawed standard implementations in Monitors, this might fail. In this case a manual overwrite is required to not have washed out colors or lose details in very dark or bright scenes.
