          Thank you for posting the link to the answer! This also fixed the problem for me.



          The Nvidia forum lists more steps. But the following worked for me:



          1. edit the file /lib/modprobe.d/nvidia-kms.conf. Change the line options nvidia-drm modeset=1 to options nvidia-drm modeset=0.

          2. Run sudo update-initramfs -u.

          3. Then just reboot your computer.

          After this, my HDMI output worked perfectly.



          It is also worth noting that the HDMI port is not detected when I am using the "Intel (Power Saving Mode)" PRIME profile. However, the HDMI port works fine again when I switch to the "NVIDIA (Performance Mode)" profile.
