Monitors stay on after shutdown

I have an issue after shutdown my 2 monitors stay on and show the shutdown messages.
As the PC shuts off the monitors still stay on and show part of the shutdown messages(half the picture from top to bottom).
I have to manually switch the monitors off or restart the pc for the messages to disappear.

I have no clue where to start analysing the problem. If someone needs additional logfiles please say so.

journalctl -b -1 >> ./shutdown.log :

Re: Monitors stay on after shutdown

Try adding nvidia-drm.modeset=1 to your kernel parameters to kill the simple-drm device. I do remember some reports of similar issues when having the modules in the initramfs/mkinitcpio, is that the case?

Re: Monitors stay on after shutdown

I used the bootmenu to add the "nvidia-drm.modeset=1" kernel parameter.

It changes the behavior during shutdown. With the parameter active it switches of one of the two monitors.
On the second one the shutdown messages are still displayed after the pc is powered off, but as before only the top half of the picture.

How do i check if the modules are inside the initramfs/mkinitcpio?
