Hello there, friendly EOS community. After having used EOS for over 3 months without bigger issues, I’ve finally ran into a problem that I can’t wrap my head around. I’m also generally still quite new to the Linux environment, so please assume that I have big knowledge gaps all over the place - also when it comes to basic things.
I’m running EOS on a desktop PC with KDE Plasma on Wayland. I have an Nvidia RTX 3060, using the native Nvidia drivers. I have 2 monitors attached: 1 TV via HDMI 2.1 and one monitor via DP 1.2. Until recently, the screens ran according to their specs (both at 60Hz) and I don’t recall noticing anything odd in the display settings. Now, after a recent yay, the display config only lists up to 30Hz for the TV. I went through the TV’s settings to see if there’s anything limiting from that side, but no such thing, I also tried different HDMI cables, including nominal 8K HDMI 2.1 ones. I’ve tried nvidia-dkms (alongside nvidia, I suppose. This one might need some clarification.) Finally, I’ve tried setting a profile manually, according to https://wiki.archlinux.org/title/Xrandr#Permanently_adding_undetected_resolutions, all to no avail.
Here are some hopefully relevant parameters:

Apologies if I’m missing something obvious and thanks in advance!
Edit: It just occurred to me that xrandr is probably specific for X sessions, right?
So here’s this while I dive deeper into the matter:
