Please add option to adjust output RGB range
Last modified: 2017-06-01 09:39:42 UTC
Hi, when using X, it's possible to adjust the Intel driver's Broadcast RGB setting via xrandr like this: xrandr --output OUTPUT --set "Broadcast RGB" "Full" or: xrandr --output OUTPUT --set "Broadcast RGB" "Limited 16:235" or: xrandr --output OUTPUT --set "Broadcast RGB" "Automatic" Unfortunately the Intel driver now sets this to "Automatic" by default and "Automatic" doesn't really set it properly all of the time: https://bugzilla.kernel.org/show_bug.cgi?id=94921 amdgpu and radeon apparently are also planned to get options to to adjust the RGB range / color space, see: https://bugs.freedesktop.org/show_bug.cgi?id=83226 When asking on #wayland on the freenode IRC channel, I was told that such an option would need to be added to the corresponding Wayland compositor and that I should submit a feature request for the corresponding Wayland compositor. So, could you pease add an option to adjust the RGB range? Regards
There's no kernel parameter for it, see: https://bugs.freedesktop.org/show_bug.cgi?id=96489 So if the Wayland compositor does not provide an option to adjust it, you're pretty much stuck.
