I have plugged in the new monitor using the miniDP - DP cable into my Macbook pro 2011 (OS X 10.9.5 )
it has an Intel HD Graphics 3000, card
The cable i am using is the miniDP out of the box, but the input menu on monitor won't let me choose 'mDP'.
The screen goes black for 2 sec randomly. This seems to be a common issue looking at your forum.
Any reason why this is not working ??
