Hello! I am on Fedora 40 KDE Edition (Wayland). I have monitor with two supported refresh rates (60, 50 Hz). How can I set custom refresh rate? I know, on Windows you can use CRU.
Hello! I am on Fedora 40 KDE Edition (Wayland). I have monitor with two supported refresh rates (60, 50 Hz). How can I set custom refresh rate? I know, on Windows you can use CRU.
I added new refresh rate for testing, but after enabling it I just get black screen.
How to fix this issue?
I’m sorry to hear that. Does this system only have access to this single display? Did you use a kernel command to modify your EDID? If so, are you able to temporarily modify your grub before booting into the OS?
