No hdmi output during boot process on MSI X570-A PRO motherboard after turning on secure boot
Hi,
I recently turned on secure boot on my MSI X570-A PRO motherboard, and since then there has been no hdmi output during the boot process from my graphics card, or the hdmi port on the motherboard.
My graphics card will only start outputting video once the OS has loaded, but this means I cannot see the BIOS anymore...
I have already reset the CMOS by shorting the JBAT 1 pins on the motherboard, but apparently this doesn't turn off secure boot, because there is still no hdmi output.
Any ideas, how to resolve this issue?
Thanks.
