[xorg] Set display to full RGB output

Depending on the monitor being used, the RGB color model supported might be either "Full RGB" or "Limited 16:235"; usually the latter is the one used by TV monitors.

To test the output setting when using xorg, first find out the name of the video connection being used by running:

xrandr

which will list the names and statuses of the available connections. Then manually change the output setting with:

xrandr --output NAME --set "Broadcast RGB" "Full"

Or use "Limited 16:235" instead.

This will not survive a reboot, therefore use whatever method suits you best to force this at every boot, eg by editing/creating the ~/.xprofile file
