I've recently installed Arch after a few years cutting my teeth on Manjaro. Thanks to the excellent and detailed ArchWiki, I've been able to get my system up and running mostly how I like it, learning a lot more about Linux in the process. There are a few things remaining that I'm currently struggling to solve, one of which is my external monitor (connected via HDMI) not being detected under Wayland.
I'm running KDE Plasma, and have installed the propriety nvidia driver for my GPU. The external monitor is detected and works perfectly when I start an X11 session, but does not appear to be detected at all in a Wayland session. I have attached what I think is the relevant info below; in the cases where they were different under X11 compared to Wayland, I have included both versions. Please let me know if any other info is required.
As the inxi and xrandr outputs show, the system does not detect that an HDMI device is connected when running a Wayland session. Looking at the output of nvidia-smi, I noticed a line that says Off when running Wayland, and the corresponding line under X11 says On. Does this indicate that under Wayland, my Nvidia GPU isn't being used, and it's always using the integrated Intel GPU? If so, does this mean that external monitors are only supported under Wayland when the dedicated GPU is being used, and I need to follow these instructions to always run the NVIDIA GPU? I don't believe this could be the ultimate solution, as the instructions I linked to also mention:
#Use NVIDIA graphics only - gives more performance than integrated graphics, but drains more battery (which is not welcome for mobile devices). This utilizes the same underlying process as the optimus-manager and nvidia-xrun options, it should be utilized for troubleshooting and verifying general functionality, before opting for one of the more automated approaches.
Any advice or assistance would be greatly appreciated.

I have solved this issue. I had unfortunately missed the section in the Plasma installation instructions which says:
To enable support for Wayland in Plasma, also install the plasma-wayland-session package. If you are an NVIDIA user with the proprietary nvidia driver, also enable the DRM kernel mode setting. If that does not work, too, check the instructions on the KDE wiki
Enabling the DRM kernel mode setting, by adding
nvidia-drm.modeset=1as a kernel parameter has fixed the problem. The external monitor is now also detected when running a Wayland session.
