Stop programs opening on 2nd monitor?

[gamerdude1989]

Anyone know how to stop programs keep opening on 2nd monitor?
I leave my pc on, when not in use, but turn monitors off... No matter which order i turn them off, and which order i turn them on... As soon as i turn monitors back on to use my pc, EVERYTHING opens up on 2nd monitor...
I have to keep moving it across to the main screen.. It will then be fine, Until i next turn my monitors back off!!!

I have been into display settings, Clicked to remember monitor based on connection.. Clicked and identified both monitors... etc etc
This was never an issue, Until i built my new pc last week, and installed Windows 11 again...

I wouldnt mind so much.. But i dont always want my side monitor on.. I mainly use that for OBS and stream chat, when im streaming on twitch...
BUt even if i just turn my main monitor on... All programs still open up on 2nd monitor.. I have to then turn side monitor on, Just to move the programs back over to main screen!
I jsut want all programs to open on main monitor, Every time i open them.. and for me to manually transfer them across to side screen, When i want..

cheers
