Hello!
I have two Dell P2415Q connected to my computer, one via DP and one via HDMI.
One of them (left) is working fine, as expected.
However, the second one (right) is having problems - while displaying the signal without problems, the OSD menu and Power button "freeze" after some time of operation - e.g. I can't change settings, and I can't turn it off. When i put my computer into sleep mode, the left display goes into power saving mode as expected, the right one however becomes pink until i wake the computer, or plug the cable..
I have already tried resetting all settings, menu settings, switching the inputs (DP->HDMI, HDMI->DP), unplugging all USB cables, or running the Display without any Cables connected at all (besides the Power cable, of course)...
However, this doesn't work - after a few minutes of operation, the display OSD and buttons freeze.
I don't think this has anything to do with the OSD lock, as this problem is occurring automatically, and only on this one display. Also, the power button doesn't work anymore, too (it still "glows" though).
Any suggestions?
Greetings,
Felix
