<pre>Following an upgrade to kernel 4.2.1 (Arch Linux X86_64), xrandr has no visible
effect on screen when switching from Full to Limited 16:235 and vice versa. The
screen appears visibly to be stuck at limited range with washed out colors,
despite what xrandr reports.
I installed and booted from the Arch Linux LTS kernel (currently at 4.1.8) and
the issue goes away. The GPU correctly outputs Full Range using the xrandr
settings "xrandr --output HDMI2 --set "Broadcast RGB" "Full" -display :0"
This issue is described in more detail here
<a href="http://forum.kodi.tv/showthread.php?tid=240397">http://forum.kodi.tv/showthread.php?tid=240397</a>
and also has an open Arch Linux bug entry here
