Windows 10: How to disable specific video output in Windows 11

Hi,I have an external display connected to my laptop via 2 interfaces. One is USB-C via docking station and then Display Port, and the other one is direct connection laptop-monitor via HDMI. Reason for that is that some applications keep disconnecting my external display when connected via docking station this is another problem which I am trying to solve.Anyway - Windows is pushing the video through 2 interfaces at the same time. They both go to the same display, which is obviously unnecessary and from time to time still causes disconnestion as well. Is there a way to make Windows to be usi

HDMI Video output disabled

I wrote software to monitor video events.

It worked fine with Windows 7 & DVI.

It also mostly works fine with Window 10 & HDMI.

However, under Windows 10, if I change the input to the monitor (say, to watch TV while a process is running, or turn it off to save power), the video output from my computer freezes.

For example, I can move the mouse over a button which changes color while being displayed, but it I do the same thing while the monitor is off, the video output isn't updated (the color of the button remains the same.)

The whole point of the software is to alert me (via audio) so that I don't have to have the video on.

Preferably

1) I'd like to tell Windows to keep doing what it's doing even if I'm not watching. (I don't watch water boil, either, ya know?)

Alternatively:

1) Buy a new/old video card with a DVI output (new computer doesn't have it).

2) Get rid of Windows 10, restore Windows 7

3) Get rid of Windows, Get Linux

I haven't gotteen to this suggestion yet - but, I've shut down half my Extensions and, now, I get the voice of the Youtube videos - but still not the video. Thought this clue might help.
