Mac Mini color issues after lock
Hey folks,
so I have a Problem, when I relog into my Mac (after locking it) sometimes my two displays go yellow, the color ius just wrong, like when a VGA Cable is not plugged in all the way. When I turn the displays off and on again its fixed. I just dont know why this keeps happening and how I can fix it.
Btw, my exact gear:
Mac Mini (Late 2014)
HP27GS Displays (one connected via HDMI and one connected via DP Mini to HDMI)
Hope someone can help me, because it's really annoying!
Thanks in advance
Mac mini, macOS High Sierra (10.13.3)
