I know I'm late on this but use DDC to control your display. You can easily create hotkeys that send a command via DDC to the display to turn-off. This would be equivalent to turning off the display using the button. Works like a charm for me. The only trick is that DDC command specs vary across monitor manufacturers but its not hard to find the right codes to send with the help of google.

Ready made tools also exist for this; search for anything that is related to DDC or EDID and you should find.

Be aware though that this does not remove the display from Windows which means that apps may find their way onto displays that are off and you will be looking for them.
