Displayport problem (mini)

Hi I bought the mini, but for some unknown reason it only connects to my ROG pg278qr monitor through hdmi. If I try a display-port cable it just says “no signal found”

My monitor has higher MHz only through the DisplayPort (up to 144mhz) so naturally I would prefer to use the DisplayPort.

Worth noting that on my regular computer the DisplayPort works fine.

I’ve tried multiple cables and adaptors.

Ive also unplugged both the mini and the monitor for a while

I found one comment that recommend turning of “secure boot”. I assume that is done somewhere within bios?

What coreboot version you are running?
