Subject: Extreme4 Z390: 5 beeps when no screen is attached

Hi,
Yes I read it, but due time shift I have your replies quite late my time, but that's OK.
With 4.10 firmware I have interesting finding - after enabling Compatibility Support Mode 5 beeps are gone. System starts without display any time. However if the display was not turned on during POST it will stay in power-save mode until next system power off-on cycle. The PC is accessible over network and reacts correctly on mouse & keyboard. I attached another LCD - the same behave.
I have 2 options to test:
1) I'm using HDMI cable, but maybe it's Display Port the primary port
2) check behave with discrete graphics card
