sceptre 27” 4k monitor (u275w-upt)

70hz

this monitor should support 70hz, but it’s not an option under xorg nor wayland. i’m able to manually set it with a modeline but it looks worse than 60hz. i’d suspect this is the cause of my modeline and not what it should look like, unsure.

modeline

you can manually configure 70z using a custom modeline. however, there’s such a bad frame jitter/stutter/lag(?) from this i’d rather go without

xorg:

$ xrandr --newmode "3840x2160_70" 609.84 3840 3872 3920 3960 2160 2163 2169 2200 +hsync +vsync
$ xrandr --addmode DisplayPort-0 3840x2160_70
$ xrandr --output DisplayPort-0 --mode 3840x2160_70

hyprland:

monitor = DP-1, 3840x2160@60, 3200x0, 1.33 # 60hz, looks better
monitor = DP-1, modeline 609.84 3840 3872 3920 3960 2160 2163 2169 2200 +hsync +vsync , 3200x0, 1.33 # 70hz, looks worse
