I have 2 monitors, one 1920 x 1080 and one 3840 x 2160 or 4k one. My main monitor is the 1080p one because it gets more fps one MC. My problem is I run MC and it says the resolution is 2880 x 1586 in F3 not 1920 x 1080 and it gets all blurry when I put it on fullscreen. Thanks in advance!
No I don't have VSR on, or in my case Dynamic Super Resolution, I dont like playing in full screen I just maximize the window but I tried full screen and changing the res with optifine but It didn't work. It doesn't change the resolution at all and just makes it so My mouse doesn't line up with the buttons.
