How do u fix the resolution so its 2560x1440 it resets for me to 1920x1080 getting a headache playing?
Wondering the same thing. I can’t seem to get any resolution running at 144hz 
Heya,
What resolution is your desktop/windows set to, and what is the monitors native resolution? Do you have the option to choose the resolution in-game?
Have a few seconds to spare? Let me know how I’m doing!
Similar issue. Upgraded to a RX 9070 from a RTX 3080 and when I opened SC2 the resolution was off, I can only select 1920x1200 at max. Even though my monitor is 3440x1440 and I was running on the RTX 3080 at 1440p for years. Have done a bunch of trouble shooting including a full fresh re-install of windows, monitor drivers, still won’t work.
