The problem
I am seeing the follownig error on the dmesg log when I plug a HDMI monitor on my Razer Blade 2021 :
[...] trimmed for brevity
[ 0.000000] DMI: Razer Blade 15 Advanced Model (Early 2021) - RZ09-036/CH560, BIOS 1.04 04/07/2021

The monitor does not show on any of the graphical interfaces provided in GNOME. I have tried several of them and the error persists. I tried switching to GDM with even less success (see this Github issue to have an idea why).
Anyone has an idea on where it could come from ?
Informations on the system
I will do my best to provide as much information on the system but if you think that a crucial piece of information is missing, please do not hesitate to give pointers !
Relevant part of configuration file
I tried both hardware.nvidia.modesetting.enable=true and false without success.
