Please use [code][/code] tags. Edit your post in this regard.

Graphics Platform: Wayland
…
$ xrandr

xrandr has extremely limited meaning on wayland, see kscreen-doctor

Looks like laptop have two cards, Intel and Nvidia

Intel was not yet bought by AMD
But the problem will be that the HDMI output is wired to the nvidia GPU and that's not being utilized by kwin_wayland

Re: HDMI port is not recognize

No kernel module operates the nvidia GPU

uname -a
pacman -Qs 'kernel|nvidia'
