but at least on my board/setup when RPi HDMI connector
is not connected to monitor then console is not switches/
ticker output continues on the serial port.

The detection is little hacky/comparison with know default
width/height.

So if you do not have connected monitor output should
work. Or your board reports different state/resolution
in disconnected case.

It would be much better if some firmware function
is know to explicitly report monitor is/is not connected.
But Get EDID block functions describes that it returns
one block unconditionally

If it could report error if monitor is not connected
then it would be better. It would worth to test that
wit different firmwares and monitors connected/disconnected
in future.

Best wishes,
