how to make one screen pitch black without turning it off / disabling it?

I have two monitors and I want only one of them to be pitch black temporarily for a certain amount of time every now and then.

I don't want to turn the monitor off because then the computer stops recognizing it and changes all of my settings and my beautifully organized desktop shortcuts.

Same goes for disabling the monitor/changing to Single Screen instead of Extended Screen.

Is there a way to do that?

Solution 1:

You can achieve this by using a 3^rd party program called Multiscreen Blank.

It has a lot of features but the feature you are looking for is also present.

• It can be used to Blank out unused monitors in a multi-monitor setup to reduce distraction.
