This might be related to the fact that some HDMI ports are only
connected to the Nvidia GPU and others only connected to Intel. That's
normal, but might not be the only factor here.

Title:
External HDMI display not working with Intel GPU
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
I have Asus UX580 laptop with intel and nvidia 1050 video cards under Ubuntu
19.10.
For some reason dual monitor setup with external monitor via HDMI only works
if I switch to Nvidia only. If I select Intel GPU or "on-demand" in Nvidia
server settings HDMI out is not working at all - xrandr shows HDMI out
disconnected.
