Question Black screen after waking from sleep /hibernation ?

[xeagle]

I've been searching for a few days for a solution to my problem but so far no luck. So here it is.
I am trying to run 6 displays in a 3 across by 2 high setup.

When I boot up all displays work fine, but if the system goes into sleep mode or hibernation, one display will not display a picture. The screen is just black except for the cursor which is always present. The cursor will move as it should when I cross into that display but it will stop on the edge of the display.

The funny part is that once the cursor does cross into another display , the next display picks it up and continues on like normal. If I have a window open in that display before the system goes to sleep I can still go and grab it, if I can find it, and drag it to another display. So that display is receiving signal but not displaying a picture. So here is my set up:
--------------------------------------
OS: Windows 11 Pro 23H2
Device name: DT
CPU: Intel Core i5-8600K 3.60GHz
RAM:16.0 GB (15.9 GB usable)
iGPU: Intel(R) UHD Graphics 630
dGPU: Radeon RX 570 Series
4 x insignia 32 inch tv 720p displays 1360x768
2 x insignia 32 inch tv 1020p displays set to 1360x768
----------------------------------------
The integrated graphics using HDMI port is the one giving me the problem. I have tried updating drivers, using different 720p and 1020p displays and no change. And like I said before it works fine when I boot up, the problem only shows after sleep or hibernation.
Any and all thoughts appreciated.

Welcome to the forums, newcomer!

You forgot to include a couple of more info about your system. Include;
Motherboard's make and model:
BIOS version for motherboard:
PSU's make and model:
Age of the PSU:

If you have BIOS updates pending, update to the latest, clear the CMOS, then use DDU to remove all GPU drivers(Intel, Nvidia and AMD). Once removed, manually reinstall with the latest GPU driver sourced off of AMD's support site, in an elevated command, i.e, Right click installer>Run as Administrator.

Once done, do the same with Intel's drivers.

Just did a bios update and put the system in sleep and hibernation mode and the display came back with picture. I will let it sleep according to my power plan and see if I still have picture.

I did a natural sleep cycle and everything seems to be working fine. The only thing that is different is that the system now posts on the display that was not working. but that is not an issue.
