AW3423DW, randomly turns black
My AW3423DW randomly goes black for about 10 seconds and shows the "DP Input Message" when it comes back:
- No obvious pattern, frequency roughly once an hour
- M0B102 firmware
- In windows 11 and in games
- Latest drivers installed (GPU is RTX 3080)
- G-Sync enabled in Windows and full screen mode
- 144Hz and 165Hz, I'm currently trying other refresh rates to see if that helps
- Occurs on two AW3423DW units that I tested but not on an older AW3420DW screen
- Happens with 3 sets of DP cables and two AW3423DWs so unlikely to be a hardware issue
- Issue has not yet happened when combining two AW3423DWs as a single "surround display"
Has anyone experienced this or has ideas for a solution?

This only appears to happen when I have two monitors connected and enabled.

Simplify the setup, test one monitor at time.
Test #1 AW3423DW on all three of the RTX 3080 DP out ports. Post the results.
#1 AW3423DW --> RTX 3080 DP out port #1 = Black out or does not black out?
#1 AW3423DW --> RTX 3080 DP out port #2 =
#1 AW3423DW --> RTX 3080 DP out port #3 =Test #2 AW3423DW on all three of the RTX 3080 DP out ports. Post the results.
#2 AW3423DW --> RTX 3080 DP out port #1 =
#2 AW3423DW --> RTX 3080 DP out port #2 =
#2 AW3423DW --> RTX 3080 DP out port #3 =

Thank you Chris, I tested this with only a single AW3423DW connected for about a week now and do not see this issue occurring.
The issue does occur with a AW3420DW + AW3423DW connected and also appears to occur when two AW3423DWs are connected unless they are combined in the Nvidia driver into a single virtual screen.
The intermittent nature of the issue makes it time consuming to test each screen on each port for many hours but so far I don't see any differences on different ports.

Do you have any additional screens connected to your GPU?

This started happening to me recently. I have an RTX3080, nVidia driver issue? I'd be playing a game or browsing, then screen goes black then starts up again after about 3-5 seconds with the DP signal coming up.
I am using dual monitors, one inside my PC that monitors TEMPS etc, and my main 3423DW. Had the monitor since May but it only started happening recently. Windows 11.
