External Monitor not detecting

Well, I installed Manjaro KDE a couple of days ago on HP Victus Ryzen 5 5600H. But when I connect an external monitor, it doesn’t detect it. I tried a couple of general solutions but none of them work. So I tried the same with the Manjaro GNOME version and there it worked (on a live USB).
Here is the full information of my system

Hi @jackcompass,

Looks like there might be something amiss with your drivers. Please provide the output for:

mhwd --list

As well as

mhwd --listinstalled

Edit:

Also this, what @bogdancovaciu said:

Nvidia Drivers and Wayland in KDE Plasma do not work yet as you might want. Gnome is indeed ahead of that but still has tons of issues with many applications.

Use X11 session instead.

Even using early kms as described here

still might not give the proper functionality under wayland session …

Thanks for the help but I solved the issue at last. All I had to do was install the optimus-manager and optimus-manager-qt (It’s just GUI to switch the GPU). The external monitor in my case was taking the output from the DGPU so I had to turn that on.
There are a couple of good youtube videos that can describe how to do all of that. This one video I found is really good.
