Edit: I’m glad so many of you have had no issues with multiple monitors. My set up is a little unusual (3rd display is an infrequently used large tv hooked through the receiver) and is definitely solveable but will take some effort (and honestly, I’d rather spend my spare time outside or with friends, so who knows when I’ll fix it.)
It’s because one of my three is a sporadically used tv that’s hooked up through my receiver system. Windows had trouble with it too and in more irritating ways. I just have to sit down and do some work to create a way to easily toggle between 1, 2 and 3 screen layouts/settings etc.
