How do you set the primary display when booting up a nMP

[Anim]

Hi

How do you tell the New Mac Pro which is the primary and boot up monitor?

It always chooses one of the side ones depending which one I have plugged in. I always want the main display to be the Apple 27" Thunderbolt model but for some reason it always chooses a side display (HDMI or a Mini Display Port monitor).

I know you can drag the small white bar across monitors in the Display->Arrangement settings menu but that doesn't change my boot up display.

Any ideas?

Cheers

That's how it should work.

Hmm, well it doesn't on my setup. Will keep searching thanks.

In my setup the boot monitor (where all the partitions appear if I press ALT at boot) is always the one connected to bus 1 (I don't have anything on the HDMI).

Moving the small white bar only changes on what monitor I have to login.
