Possible to blank monitor 1, while monitor 2 is in use?

4 discussion posts
Hi all,
I'm using DisplayFusion (latest Steam verion) on Windows 10 Pro 1909, with 2 displays, Dell U4919DW and an Epson EH TW6700 LCD projetor.

I want to make the Dell monitor go blank when I run movies/Netflix in fullscreen on the projector. I know I can use monitor fading, but that still leaves the display on - I'd like to make it go to "sleep" while I watch movies. I know I can turn it off using the physical button, but I have my reasons for not wanting to.

Can DisplayFusion do this for me, somehow? I've checked the manual and the settings, but so far have found nothing.
Any help much appreciated. I work in IT, so I'm not afraid of "complex" solutions. Automatic/hotkey based/other methods - hit me with your best shot.

Thanks in advance!

I used the information at Working with DisplayFusion Monitor Profiles to create monitor profiles that disable/enable certain monitors and use hotkeys or system tray menu to change them.

As far as automation goes they appear in triggers and I think scripted functions but I haven't tried this so I don't really know what's possible.

As @SnakeArsenic mentioned, setting up a Monitor Profile with the monitor disabled and then loading that via hotkey would be the best way to do that

If you have any further questions, definitely let us know.

Thank you both for your help, this method is not bad at all.

But I would much prefer not to "disable" the other display entirely this way; I can see that it means that I have to set the active display as primary, and that means moving all open windows there.

So, although I know I'm being a little "greedy", I'd like to clarify my hope a bit: Is there a way to simply blank one display at will, without causing any windows to move around?

I really only want the video player to show up on my projector, and I'd like for the other windows I already have open on the monitor to not be shuffled back and forth, forgetting their positions, etc.

I suppose I might set up windows profiles for them all to avoid this, but that seems needlessly complicated compared to what I actually want to do - and I could probably never get all of the possible windows I might have arranged that particular day into a profile.

Once again, thanks in advance for taking the time to read and think about my question.

There isn't a way to make one monitor sleep, no. The only other way to blank it would be to use Monitor Fading, but as you mentioned, the monitor stays on when you do that
