Created attachment 186719 [details] Scr I have an acer vg240y monitor. It supports 75Hz. But now the option to select 75 Hz is gone. I noticed the other day that the picture had changed and saw that 60Hz was the maximum that could be selected.

My monitor supports 75Hz in both Windows and Linux KDE Wayland, but recently the 75Hz option has disappeared.
Thanks for that information. I'll let the kwin developers reply from here. Note: In the screenshot, the monitor has a resolution of 2560x1440
I have 2 monitors. The main one is 2560*1440x144 Hz and the second one is 1920*1080X75 Hz. The problem with the second monitor is that it cannot be set above 60 Hz.
KWin doesn't filter out any modes, that's the driver's job. Please report this at https://forums.developer.nvidia.com/c/gpu-graphics/linux
