I’m running KDE Plasma in a wayland session. My monitor is capable of a higher refresh rate . I changed my HDMI cable to an ultra. I checked the connections. The drivers are up to date. My refresh rate is set to 60 Hz and it does not let me change it. Has anyone ran into this?
There are a lot of reasons that a monitor will not support the higher refresh rates.
What does kscreen-doctor -o report?
