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.

  • This sounds similar to the issue on earlier Pros. Basically if the ‘gpu’ or in this case adaptor is not Mac flashed you get no image until the drivers are fully loaded from the OS. That is essential a no-fix. – Tetsujin Jun 13 '19 at 11:18
  • Well that would be weird as the GPUs were the factory ones; the AMD Fire Pro 300s that came standard. – Almo Jun 13 '19 at 18:25
  • Ach, sorry, I misread. Ignore me ;) – Tetsujin Jun 14 '19 at 5:14
  • haha no big deal! :) – Almo Jun 14 '19 at 13:02

I was not able to solve the problem with that connection. However, it works fine with an HDMI to HDMI cable.

Leaving the question unanswered, as I'd still like to know why the Thunderbolt to Displayport connection didn't work properly.
