did you check with a DP to DP cable, or some kind of DP to HDMI / DVI or other kind of dongle? I believe at least one Protectli model has an eDP interface wired as the DP port, which only works with "pure" DisplayPort and not DP++, so no passive HDMI dongles will work.

both DP-DP and DP-HDMI

It also depends on a monitor used. Irecall some monitors worked, some not. I think it had to do with 1920x1200 and 1920x1080 resolutions (the latter worked).
