No display when waking from sleep, repeating issue across multiple PCs

[Grim5]

I need to figure out why this keeps happening. After moving my mouse or press a button on a keyboard when the PC is at sleep and then the PC will turn on but no image is displayed on the monitor and then I have to do a hard reboot (hard reboot because pressing the power button on the case does not make windows shut down, I have to pull the power out). What makes this issue more complicated is that it's not consistent; sometimes an image will be displayed on the monitor and sometimes it won't.

This issue does not seem to be a single piece of hardware related because it's happening to me on multiple Windows 11 PCs and the PCs have different internal hardware.

So based on that I think the issue is either caused by:

* A Driver
* Some installed App
* Bios settings
* Windows power settings

But I don't know what to do from here to narrow down the problem.

I have noticed after checking through the windows event viewer logs that when the pc successfully turns on from sleep and I get an image on the monitor it generates logs in event viewer saying the pc power state has changed from sleep (S) to a new awake state - and all the times where it fails to start up and I get no image, I can see there is no log in event viewer showing that the PC woke up from sleep even though the fans and rgb in the case is going

May be a monitor issue. Post what monitors you have. Go to your monitor manufacturer driver page and download the driver, in device manager install the downloaded driver. Should see the monitor name in device manager rather than generic monitor.
