We have older HP EliteOne 800 G1 All-in-One Desktops. All-in-Ones are similar to a laptop in that the screen is built-in. The monitor cannot be powered off separately from the PC.
The Monitor Crashes upon sleeping or waking from sleep. CTRL-ALT+F2 is usually dead too. One can still ssh back into the system from another machine. Sometimes, killing all Xorg processes will fix it, but since it also kills all the tty related stuff, rebooting is the only way to get the system back. Manually commanding the AiO to goto sleep would not replicate the problem, only allowing the timeout to expire and let it fall asleep. Tons of hours into this problem! The best I have found that seems to work is to disable the ScreenSaver and PowerManagement for the Display for all users and the system logon screen as described here in my LinuxMint forum call for help.

The linuxtv / Hans website says the EDID Fails because it is "Missing Display Range Limits Descriptor."
