Just giggled as my last meme mentioned trouble with displays and appropriately, a large chunk of the replies were “well MY displays work just fine!” (And charmingly, many were thoughts of things to check, other distros etc. It’s a very kind community, though that may also be the fediverse.)
How mismatched do they have to be though?
I have 2 monitors, 1 Benq, another MSI. 1 @ 60Hz and another @100Hz.
When I move a window with VSync to the 100Hz monitor, it starts doing 100Hz and changes back to 60Hz when I move it back to the 60Hz monitor.
It works fine when I 90° one of them.
Though the resolution and screen dimensions (hence pixel pitch) are the same. So is it one of these that needs to be different?
