--- Comment #3 from mattias.slabanja at gmail.com ---
Found bug https://bugs.freedesktop.org/show_bug.cgi?id=93198 (which reported
that resolutions larger than 1920x1080 wasn't working through DP).

It seems I experience the same, or a similar behavior.

In my setup, the monitor's native resolution is 2560x1440.
If, using xrandr, lowering the DP resolution to e.g. 1920x1200 or 1920x1080,
the DP signals starts working.
Setting the resolution back to 2560x1440 again results in a black screen.

As far as I can tell, this is reproducible and repeatable.
