GUYS! just got it to work and finally my display looks amazing with my mac mini m1! My monitor is a gigabyte with 1440p resolution and is connected with USB C to DP This is what I did: 1.- installed better display 2.- go to settings/displays 3.- in resolution scaling section: set native resolution to 3840x2160(4k) (yes higher than my display's native resolution) set default resolution to 3840x2160(4k again) and 144hz (my display higher refresh rate capable) click on ''show advanced settings for native smooth scaling'' and check mark ''add a near-native hidpi variant for the native resolution'' 4.- apply and restart the mac 5.- enter to system settings/displays (mac settings, not better display settings) and check mark ''show all resolutions'' 6.- scroll and select your hidpi resolution! With my native 1440p display now I can select 2528x1422 hidipi at 144hz and it's AMAZING! here are a screenshot of better display settings and mac display settings:
