Hey guys;
I have done a lot of searching - here and through Google - on this problem. It appears to be quite common, although the particular conditions that exist on my system may be somewhat unique - so I am creating another thread.

I have not updated the BIOS since this problem started.
The most important fact about this problem is that it started after I upgraded (in-place) to Windows 11, then decided to roll-back to Windows 10. Since I was within the window MS allows for roll-back, the system did a restore from the files that were backed up during the upgrade.
The conditions that exist when the problem occurs:
I have the system set to shut down the monitors after 20 minutes, but do not allow sleep mode.
After the 20 minutes, the monitors will blank. When I return, I must hit any key or move the mouse to bring up the lock screen and enter my pw.
When the problem occurs, the screens (all of them) are black, with the backlights on. All three monitors are indicating that they are powered on - not in sleep mode as they would be when they are normally blanked.
I am usually unable to bring up the lock screen, and a hard shut-down and restart are required.
Once - and only once, the lock screen came up on its own after about 5 minutes, but other times I have waited as long as 10 minutes and it did not come up.
The problem never occurs when I power up from shut-down.
It does not appear to matter whether any apps are open on the desktop when Windows shuts the monitors down.
I have run sfc /scannow.
The first time I ran it, there were corrupted files that were repaired, but the problem continued to occur.
I have run sfc /scannow several times since, but no problems were detected.
I ran Crystal Disk Info, and it reports that both SSD's are 100% healthy.
I have also run a disk check on both SSD's but no problems were reported.
I have checked the Event log. There is nothing relevant there. The only errors I see are the unexpected shutdowns that I performed when the lock screen would not come up.
I have multiple devices connected to USB ports, but I have not tried unplugging anything yet.
I tried uninstalling the Steam client, which was running on Windows startup, but that did not solve the problem.
I believe that the process of restoring Windows 10 after an upgrade to 11 is what caused this problem.
I have Windows 11 installed on a separate partition (multi-boot). I also have Ubuntu on another partition.
At this point, I am ready to begin migrating all of my apps to Windows 11, but I would first like to know what happened to Windows 10.
If the problem persists on Windows 11, then I would have to suspect a hardware problem - with the PC itself or one of the connected USB devices.
I will have to try running Windows 10 without any of the unnecessary USB devices, but since the problem occurs so infrequently it will take some time before I will know whether the problem is a USB device.
Any ideas / suggestions?
Thanks for your help
