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?
EDIT: Extra data... if Win 10 sleeps, the monitor will not wake up.
