Windows 10: Disabling monitor auto detection in windows 10

So the previous thread for this was disabled, with the last update being in 2019... but it's STILL an issue in 2021?! There still doesn't seem to be a way to disable TMM?Whenever my PC goes to sleep, or locks, it moves EVERYTHING to one of the screens, in addition to that, my PC is randomly cutting video signal--the entire screen turns black for a moment, then I get a "Display Port 1" UI pop in the corner, and the signal comes back. It's making working from home, or gaming, or doing anything on 2 screens next to impossible.I'm using 2 Samsung Odyssey G7's and an RTX 3090.

Disabling monitor auto detection on windows 10

I use 3 monitors right now. 2 of them are working great but the main one is having a problem.

when I turn off my primary monitor (Dell s2716dg) the pc does not recognize the monitor and all my desktop is messed up.

I found people are talking about disabling the monitor auto detection to solve this problem but I can not find how to disable it.

Hope you have answers for this problem even if it's not disabling the auto detection and it's another way of solving this problem.

Also I have the same problem with a clone setup of my Dell display and my TV.

I got the blackouts every few minutes cause Windows auto detect the TV again and again.

The key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\TMM is not avilable unter Windows 10 in the latest version, so how to disable monitor auto detection in windows 10?

thank you
