I can not put the maximum hz monitor, the monitor supports 100 hz, but the default is 60, when selecting 100 fades the screen and remains 60, tried through xrandr to add resolution with 100 hz, but the same does not work
I think this is a known bug and will be resolved soon with an update. You can do a search and see as there has been a few postings about this.
FYI xrandr wil only work if you are use X11 and not the default of Wayland.
Another user had an issue with monitor refresh rate and it was an issue with the monitor. We tracked that down by checking the EDID from the monitor.
I’ve tried setting the resolution to X11 but that doesn’t help, the monitor shuts down and returns 60.
