OMG, this solution was so simple, but completely just worked. Just mirrored the main display and fixed individual refresh rates, even works when turning the extender on and off. Thanks a bunch for the inspiration! Had my head breaking over this!
Hmm, hadn’t thought of just setting all the displays to mirror mode, might want to test what that does (especially since the displays are of varying resolutions and refresh rates). I suppose it could work.
I have thought of a physical switch but i haven’t had any luck finding a prebuilt one and I don’t much have the electronics know-how to build one.
Didnt know this, nice, thanks :)
