One of 2 monitors goes off intermittently
Version 1909 (OS Build 18363.836
One of my 2 PC monitors has just started going off intermittently. When it goes off it stays off typically about 30 seconds and comes back for a few minutes. It has done this once or twice before buy many many weeks ago and previously many weeks before that.
The power cable is firmly attached. I would appreciate any suggestions a to what could be going on.
