HDMI disconnected Ubuntu 24.04

Hello and thanks for all the work you do.

In a fresh Linux on HP Zenbook computer, I don’t succeed to connect a second screen.
xrandr says that HDMI-0 is disconnected.

I disable secure boot, i tried to set

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodest"

it doesn’t work so i try

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvidia-drm.modeset=1"

I try several nvidia-driver and X Free driver also.

What is weird is that a same computer finnally succeed to work with nvidia-driver-550-120.
But installing it by hand doesn’t work in this second computer.

Here is my bug-report

Thanks for your help, it will be very precious

Is there anyone with the same issues ?

We tried with USB-C → HDMI cable but it doesn’t work either.
