I have tried disable or uninstall the 'Generic PnP Monitor' in Device Manager, totally no change.
I also tried some commandlines using postmessage function to set SC_MONITORPOWER to 2, this method succeeded to turn off the display, but the monitor was on when I move the mouse...
So is there a way to keep the display/monitor off while I operate the computer remotely? like unconnect the monitor, or make the Windows stop sending signals to monitor?
(Not physical power button method in our case)
Thanks in advance!
