video-linux

Remove that one:
sudo mhwd -r pci video-linux

Reinstall the proper driver with:
sudo mhwd -i -f pci video-nvidia

Might consider to update the BIOS

Maybe you need to enable early KMS, see here

Switching to Nvidia drivers from Nouveau with mhwd fails

sudo mhwd -r pci video-linux then sudo mhwd -i pci video-nvidia On gnome you might have to enable early kms. As administrator edit the /etc/mkinitcpio.conf and make the MODULES= line like this MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm) then run from terminal: sudo mkinitcpio -P sudo update-grub Also, you probably have autologin on and is trying wayland session and not always starts (at least on my end does funky things)

But, before that, can you set a new resolution in KDE Plasma System Settings > Display and Monitor > Display Settings and does that survive reboot? If not, did you try with a new session instead of a saved one in Settings > Startup and Shutdown > Desktop Session

Also, maybe you need to create a fixed layout via Nvidia X Server Settings and modify the /etc/X11/mhwd.d/nvidia.conf accordingly.

  Sound Server-3: PulseAudio v: 16.1 running: yes
  Sound Server-4: PipeWire v: 0.3.57 running: yes

Might want to address that too. See this:

Steinberg soundcard stopped working

Hello, By this i gather you should either properly switch to pipewire or properly keep using pulseaudio, but not both at the same time. With pipewire there are some advantages tho. By installing manjaro-pipewire and pipewire-media-session instead of wireplumber all should be fine.
