On the Pi4, it was necessary to include the following lines in /boot/config.txt for it to boot (and not hang indefinitely) if there was no monitor connected:
# uncomment to force a specific HDMI mode
hdmi_force_hotplug=1 # allow Pi to boot with no monitor connected
hdmi_group=2
hdmi_mode=82 # force 1920x1080x60 even though monitor can't be auto-detected
hdmi_force_hotplug=1 was the crucial one; the other two forced the screen resolution to 1920x1080 (for VNC connections) even if there was no monitor to negotiate the resolution with the Pi.
Is there anything equivalent for the Pi5? I gather that the file has been moved to /boot/firmware/config.txt. I'm reluctant to change the file in case I do something that stops the Pi from booting, which would mean I would lose the ability to undo the changes in the file...
I've noticed that headless booting is a bit hit-and-miss so I want to make sure the Pi is "bulletproof" before I move to a situation where there is no monitor, and only SSH and VNC network connections are possible.
