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

I was curios of the same thing and i just disabled CSM and my system now uses the hdmi monitor over the vga one (B450M Steel Legend with Ryzen 5 3600).]]> Sun, 01 Dec 2019 20:18:08 +0000 https://forum.asrock.com/forum_posts.asp?TID=12954&PID=70635&title=bios-boot-wrong-monitor#70635 https://forum.asrock.com/forum_posts.asp?TID=12954&PID=70633&title=bios-boot-wrong-monitor#70633 Author: Tentaurus

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!?]]> Sun, 01 Dec 2019 18:43:44 +0000 https://forum.asrock.com/forum_posts.asp?TID=12954&PID=70633&title=bios-boot-wrong-monitor#70633 https://forum.asrock.com/forum_posts.asp?TID=12954&PID=70614&title=bios-boot-wrong-monitor#70614 Author: gizmic

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. ]]> Sat, 23 Nov 2019 20:10:35 +0000 https://forum.asrock.com/forum_posts.asp?TID=12954&PID=70338&title=bios-boot-wrong-monitor#70338 https://forum.asrock.com/forum_posts.asp?TID=12954&PID=70337&title=bios-boot-wrong-monitor#70337 Author: Tentaurus

Which GPU are you using?
