3. Color Management
If your TV is limited range. Go to System -> Video Output and choose "Use Limited Range", disable Dithering.
If your TV is full range. Go to System -> Video Output and unselect "Use Limited Range" and enable Dithering with 8 bits.
If your projector is of low quality, use a dithering setting of 6 or 7 bits.
Remember the above settings only make sense, when you output in Full Range (or in the special Video Range 16:235, that I provide in my custom kernels). With the default xrandr setting of Limited 16:235 - those settings are totally counter productive.
@ fritsch:
In another thread you wrote:

When I try the proptest command on Ubuntu, it is not being recognized and not offered to be installed.
Can you possibly explain some more how to do it? And maybe that way we could set BroadcastRGB=Full even before X starts?
Just came across this:
