I have a monitor I share between my new mac mini m1 and my work laptop. I set up Mac OS to use the 1440p “low resolution”, because the highest one only works with 30hz on this monitor.
WoW is set to use the default resolution and 100% scale, and looks sharp and everything works well. If, however, I switch the monitor’s input to the work laptop, when I come back WoW looks blurry. Going into the graphics setting I see the resolution is still set to Default but the scale shows 1080p (at 100%).
To fix it I need to “change” the resolution to Default (not really changing it) and apply. Then it goes back to 1440p at 100% and everything looks sharp again. At least I have a work-around, but this gets old pretty quickly when I’m coming back to WoW once in a while to look at my mission table while working, or if I need to look at some work thing while playing.
