Fedora 27 KDE Stuck at 48 Hz Screen Refresh Rate

asked 2018-01-24 15:49:11 -0500

Recently I noticed that my screen refresh rate in Fedora KDE was stuck at 48 Hz. Changing it to 60 in the display settings had no effect, as several tests revealed that it was 48 Hz. I thought the culprit might have been TLP, but even after uninstalling that, the problem persisted. Does anyone know what might be going on here or how to fix it?

I tried all of the possible VSync settings and none of them had any affect. The actual display seems to have been set to 48 Hz.
