I've just installed the Zorin OS Pro on my Samsung Galaxy Book 2 (i7 1255u + Intel Iris XE) and it's not recognizing my external monitor via HDMI.

I have already tried to start Ubuntu with Wayland, switch from gdm3 to Lightdm, reverse my HDMI cable, disable secure boot, update all drivers. Can someone help me with it?
Given your list of things you have tried already, I think it is unlikely to be drivers. Some motherboards restrict Additional monitors as well as power output.
Can you please check your BIOS / EFI settings on boot?
You would be looking for something like 'multi-monitor' support under Advanced > Graphics Configuration.
You likely will have to search the web for things...
This thread may get lucky in having a user who has owned a Samsung similar model knowing what hoops they make us jump through to access our own machines these days.
And this is riding on the guess that it is a hardware setting issue. It seems likeliest to me at the moment...
Don't know if this helps but i remember seeing somewhere that the Galaxy Book 2 or Galaxy Book 2 Pro (forget) needed nomodeset added to grub to work on kubuntu 22. For video. Since ubuntu 20.04 is older and that is what Zorin is based on, try that and see if it helps?
But i do know i had trouble with my flex book alpha and it was because they nerfed the port on purpose like <insert favorite sentence enhancer here> if not using a samsung android image
*excuuuuse me, they customized it and the proprietary drivers are only supplied on the flex alpha image my mistake
