I have an AOC 2590G4 display that is missing the 1920x1080 resolution. I was using Ubuntu latest before with no issue. This is the first time using KDE Neon so bear with me please. I'm connected to my Radeon 5600XT directly DP-DP. I've tried to disconnect-wait-reconnect with no change. I've tried following this https://www.tecmint.com/set-display-screen-resolution-in-ubuntu/ guide but, the resolution doesn't change. Any idea or troubleshooting you could recommend?

I have a secondary screen plugged in via HDMI with no issue as well.

If it helps, here is the xrandr output:
