Monitor randomly turning on


I've only had this issue since installing Win10, did not have this issue with 7 or 8. I have the monitor set to turn off either after 10 minutes of idle, or 1 minute after locking the computer. With 7 and 8, it stayed off until I woke it with the keyboard or mouse. With 10, it's randomly turning on on its own (for about 1 minute, then turns off again).

Powercfg -lastwake shows nothing. I checked event viewer, nothing in either system or application. HOWEVER, if I go to security, there are "Microsoft Windows security aduditing" entries that match EXACTLY the times that the monitor turned on. Is there anything I can do about this? Last night it pissed me off so much that I just yanked the power cord out of the computer.

 

Dual Monitors randomly turning off then on

So i have a user using a Dell Optiplex 7040 on Windows 10 Enterprise 64-bit OS. The user complained of her 2 monitors turning off then off randomly while she was working. When the monitors would come back up, all her icons would be rearranged either all
on one monitor or the other. The 2 monitors she had were rather old and were both using a display port to VGA adapter. I decided to just replace both monitors with 2 brand new Dell P2217H monitors. These monitors had a display port so there was no need for
adapters any more. I went to check on the user to make sure everything was good and she said it was better. She said that while the monitors still turn off briefly from time to time, her icons no longer are rearranged. I got on her PC and made sure that both
video drivers are updated, which they were. Basically the same issue is happening, on 2 totally different monitors, so this tells me its the PC, but what? Drivers are updated, the cables are new, and the problem intermittently. Sometimes just the right monitor
will turn off and the left will stay on, and other times the left monitors turns off and the right stays on. Never together. Any help or suggestions would be appreciated.

 

PC Monitor turns off randomly?

Yep - hence the suggestion earlier to try a different monitor to rule that possibility out. That said, most monitors sold in recent years (even budget monitors) use LED backlighting - which are much more reliable than CCFL/inverter backlighting.
