Why does my Displayport monitor not turn on when selecting a boot drive?

by Almo   Last Updated June 13, 2019 03:12 AM

I'm on OSX 14.5, with a MacPro 2013. I have an ASUS Displayport monitor, and ordinarily it works fine, both in OSX and from Windows 10 on a Bootcamp partition.

But if I boot the Mac holding Option to open the boot drive selection screen, the monitor does not turn on.

How can I get this to work?
