Hi,
I have a new video card (rx6400 4gb)
It works but there is a problem using BIOS - there is no video output during boot until the OS starts.
So if i press F10 I can hear a beep & i know BIOS is up, but there is no video.
If I use the motherboard HDMI instead of the rx6400 HDMI, then BIOS is displayed normally.
How do I get video output pre-OS using the rx6400?
(I did make another topic about this in the gaming section, but it had other questions & was overly detailed, so just the BIOS video issue is what I want to get to first.)
