Screen goes blank randomly on OpenSuse Leap 15.2 with Nvidia Quadro 4000

Every once in a while my screen goes blank for a few seconds. After it happened once, it tends to repeat increasingly. I can fix it temporarily by switching the DP-port on the Quadro 4000. Most of the time it happens when viewing videos. Playing games is not an issue.
