So I disabled CSM and it still boots VGA instead of HDMI.

I have an Asrock A300 with Ryzen 5 3400G

OK, in the meantime I got it how to enable / disable CSM!
But CSM is disabled. I use UEFI!
But Bios is booting always with VGA!
There's no setting to change the primary display port!?

I do a boot in UEFI Mode!
But there's no option to change the primary video device?!

Look in the bios if you can find an entry for selecting the default display output.

Or as i already posted: Set the bios to UEFI mode, meaning disable CSM.

Which GPU are you using?
Or do you have an APU using the onboard connectors?
