I’m using EndeavourOS + KDE Plasma on my laptop. Everything was fine under normal usage, but when I connect an external monitor (75Hz) via HDMI, the display quality is very poor. It seems to have a refresh rate of around 30-50Hz. The images appear to be stuttering. Additionally, the FPS in games running on the external monitor is very low (even though it’s running with Nvidia). I’m not sure what to do.
Note: There were no issues with the display while using Windows 10. I’m sure the cable and monitor are in good condition. ASUSTek is my external monitor.

Normally, I play Metro 2033 Redux at a stable 60fps.
