<pre>I've compiled drm-tip kernel with current git head master of today and created
the debug logs.
The first one logged how I unsuccessfully tried to switch from 60Hz to 48Hz (it
works on Microsoft Windows).
The second log shows how I loaded a custom EDID that includes 60Hz, 50Hz and
48Hz resolutions. The Intel Linux graphics driver doesn't pick them up and and
just falls back to 60Hz, which also incorrectly uses limited brightness level
range ("TV range", washed out image with PC display).
I can load the very same EDID on Windows (can be installed via Windows Device
Manager as monitor driver) and there 60Hz, 50Hz and 48Hz are correctly
available and also correctly use full brightness level range ("PC range", looks
correct with PC display).
I think it can't hurt if I attach the EDID here.</pre>
