I’m running KDE wayland with proprietary Nvidia drivers on CachyOS, so far I haven’t found a way to set a custom monitor refresh rate, on windows I could use the Nvidia control panel to make one (going from 60hz to 75hz). kscreen-doctor doesn’t let you set “unsupported” modes, the kernel launch option of video=1920x1080@75 didn’t work, somehow. So how would I do it?
Yes, but all it entails is setting an output mode with a higher refresh rate than the default one. I am using wayland, though I haven’t found a way to set a mode that isn’t reported by the monitor itself.
