Unable to Connect to External Monitor

When I run xrandr --auto --verbose after plugging in the monitor I get the following error:

crtc 4:    1920x1080  60.00 +0+0 "HDMI-1-0"
xrandr: Configure crtc 4 failed
crtc 0: disable
crtc 1: disable
crtc 2: disable
crtc 3: disable
crtc 4: disable
crtc 5: disable
crtc 6: disable
crtc 7: disable

crtc 0: revert
crtc 1: revert
crtc 2: revert
crtc 3: revert
crtc 4: revert
crtc 5: revert
crtc 6: revert
crtc 7: revert

The monitor is recognized by Gnome Settings, but when I try to connect it nothing happens.
When on Wayland the display does not appear in Gnome Settings.

System Info:

CPU: Ryzen9 6900HX
GPU: RTX3070Ti
Distro: Arch
Display Server: X11
Relevant Kernel Parameters: nvidia_drm modeset=1 (though I still had the issue when these were not set)

How should I go about further debugging / fixing this?

On a laptop, HDMI ports are usually routed through the external GPU, which is being disabled by nvx. You will need to enable the GPU via nvx on before it your ports will work. You may also need to sign out of any existing desktop session and sign back in before the connected monitor will be detected.

I have the same problem, but without error message.
System info:

CPU: Intel(R) Core(TM) i7-10750H
GPU: GeForce RTX 2070 Mobile / Max-Q Refresh
Distro: Arch
Display Server: Gnome/Wayland

I have already turned my gpu on and signed out and back in, but it still doesn't work.

Same issue for me on Hyprland. nvx-status reports on, but nvidia-smi -q reports

    Display Mode                          : Enabled
    Display Active                        : Disabled

It's odd because nvx ps outputs

3827 Xwayland
3307 Hyprland

but Hyprland does not recognize any external displays.

This is the output of nvidia-smi:
