Hello,
 
I have a multi-monitor setup (2 on DP and one on HDMI) with a GTX 1080 Ti and Win 10 64-bit. I've noticed that for the past several weeks (maybe 8 or so) that when my monitors enter standby mode due to PC inactivity, there's a 50-50 shot that when I move the mouse or hit a key on the keyboard that they will not turn on. I have the monitor sleep time set to 30 minutes, but the PC sleep setting is disabled. The PC functions normally otherwise (I get music/youtube to play and the like) and I don't see any errors in the system event viewer suggesting there was a GPU driver issue. 
 
What I've tried:
- Unplugging the cables and plugging them back in
- turning the monitors power off/on
- updating GPU drivers (445.87 - that was the second time I tried updating drivers)
- Different combinations of monitors (ie all 3, different pairs and only 1)
- different DP ports
 
The only way I've been able to resolve the issue is to manually power down the PC and restart it. 
 
I tried searching this and other forums, but it seems the only results I can find are related to the PC entering sleep mode which doesn't pertain to my issue. 
 
Any thoughts?

Late reply but I haven't been to the forum in a while ---
 
I had/Have the same issue with my 1070 Ti FTW2 but the advise hear from Sajin I believe was to remove the Nvidia HD Audio Driver and this has seemed to mitigate the Issue - until 446.14 - then it was back but seems to have stopped again and reinstalling the Drivers
 
I'll see if I can find the Post from last year...  EVGA even sent me a new Card as they thought it was the Card and Benq swapped out my monitors as well , as did Startech for the DP cables but the only thing that helped was Sajin's advice.
 
KB.
 
Sorry could find it ....maybe it was late 2018? I can't look that far back apparently so @Sajin  will maybe drop in and confirm.

Yep, removing the nvidia hd audio driver, and only running the standard microsoft driver will help with sleep issues. 

It's not a sleep issue. The issue is the monitors are not showing a display after they are in standby. The system is still running and has not entered sleep mode.

You might, as a test,  have to go clear back to say the 411.XX driver series. What version of Windows 10 are you using?
