I created the profiles, and it switches just fine, but then Im left with a TV that says LOST SIGNAL on the screen, and a receiver running that I dont want on. So I turn them off.. And then the two desktop displays lose signal and go black...

How do I fix this? Ive tried so many damn programs, and very willing to pay money to get it working right.

edit: Its using an RTX 5080 on windows 11
edit2: Even leaving all 4 displays active and turning off the TV and Receiver still makes the two other displays go black..

*** SOLVED ***

It was my Onkyo Receiver. I guess it doesnt gracefully disconnect and windows gets confused. Gonna try a passthrough edid emulator between it. Sorry to bother yall. ]]>
