Basic info:
RHEL9.2
NVIDIA drivers 535.86.05
monitors: two 1920x1080
Quadro T1000 Mobil
Gnome 40
Problem:
when I maximize a window or go full screen the window only covers 1 monitor and I want it to span both. I have tested this with a gnome-terminal by right clicking and selecting maximize, and by pressing F11 to go full screen. I have also tested this with Firefox. The final goal is to get this to work with Chromium, in kiosk mode.

I have tried several different settings for xorg.conf with some that don’t work at all, and none that allow me to go full screen across both monitors.
I am not an expert on xorg.conf settings, and I can not seem to find a complete list of options for the nvidia driver.
The following are some excerpts out of the Xorg.0.log file:
