If the display uses Mini DisplayPort, connect it the the DisplayPort connector on the card using the DisplayPort to Mini DisplayPort cable that came with the card.
If it is the Thunderbolt version of the display, it can't be used with a Mac Pro.

They included the wrong DisplayPort to Mini DisplayPort adapter. The correct adapter should have a female Mini DisplayPort connector, not male. You could buy the correct adapter or you could add a F-F Mini DisplayPort coupler
Try calling the, and asking for the correct adapter. They fo say:
"Connect to mini-DisplayPort displays through the included adapter cable"
