I came to this forum after I developed the black screen symptoms.
Triggering eventI upgraded my monitor from a 4k 60 Hz, to a 4k 144Hz HDR display.
Symptoms;- None at all at 60 Hz. on the 60 Hz. Monitor.
- @ 144 Hz I started to get random but frequent "Black Screens" every 5 minutes or so
- Black screen lasted 3-12 seconds,
- sounds continued to play
Actions Taken;- I followed a number of the suggestions in the forum regarding changes to power saving etc. There was some improvement, but the problem persisted.
- I noticed there was some correlation with events associated with xbox and other gaming services on my PC. So I uninstalled these and there was a slight reduction in frequency of occurrence, but the problem did not go away.
I thought on this a bit more and then reset the refresh rate to 60 Hz. on the 144 Hz. MonitorThe problem went away. Solution;Realized I had an old 4k 60 Hz. Displayport 1.2 cable.
In my case the local computer store has a very good return policy so upgrading the cable was risk free. If your circumstances are similar this is definitely worth a try.
I took a trip to my computer store and purchased a
reputable Displayport 1.4 cable rated for 8k @ 60 Hz / 4k HDR @ 144Hz. I installed the cable, reset the drivers etc. and set the monitor to operate at 144 Hz.
EDIT: After 2.5 days, or approximately 30 hours of game time, there has not been a single repeat of the black screen or any other windows logs. So in my circumstance I can confirm the DP 1.4 cable fixed the problem. Update: After almost a year now, the problem has never reoccurred. A quality DP 1.4 cable fixed this for me permanently.
