Q: How does the MacPro determine which monitor is primary
I have a MacPro (late2013) using Yosemite with an Apple Thunderbolt Display and a slightly older Apple LED Cinema Display. The older Apple Cinema display shows as the primary monitor when the computer starts and if I have sound coming from the monitors—even though I have switched the white bar in preferences to the Thunderbolt display (the display I have facing me and the one I want to be the primary monitor—the other sits off to my right).
I have played with plugging the monitors in to different input ports on the MacPro but nothing seems to switch which is primary. So I'm curious how the system determines which it sees as primary and which secondary
Thanks for any input
