Extreme4 Z390: 5 beeps when no screen is attached

   Hi AsRock team,

I made some progress that gives me suspection, that the issue is caused by the motherboard. Here is why:

Reassembing the PC didn't brought any progress

Updating UEFI to 4.10 didn't solve the issue

Enabling Compatibility Support Mode in UEFI causes, that system boots every time - no more five beeps

If the display is attached to any of digital ports, it must be turned on within the first seconds since powering PC, to be recognized by motherboard

If the display attached to digital port was not recognized at POST time, the PC must go over power cycle - hard or soft reset does not bring it to life

The same applies to display attached to discrete card(!)

The issue does not occur for analog port on motherboard(!)

Are there any settings, that are giving priority to analog port over digital ports? Is there anything I could do to make digital ports be default one?
