The game runs fine on my MBA M1 by itself. But there is an issue when I try to play on external monitor.
D3 doesn’t recognize other resolutions supported by the monitor. Native top rez on MBA is 2560x1600 with 16:10 aspect ratio. While my monitor is 4k with 16:9 ratio.
Top resolution I can run is 2560x1600 with black bars. I tried it with the other monitor (1080p). It also runs with black bars.
So, my question is simple, can I change config files somewhere or add a special command to launch the game in desired resolution on desired display?
P.S. and is there somewhere a setting for UI scaling?
P.P.S. the absurdity of situation is that, when I switch to windowed mode, game renders in native resolution of the monitor. Then I can drag borders of the window and fill almost whole display so the game runs in somewhat 4K.
