I have a Mac Pro with the ATI Radeon HD 5770 card that I'm trying to use with both a DVI and Mini Display port adapter to show dual screens and it crashes the video display when I plug in the second device.

 

This happens regardless of which is the first device (DVI or the MDP) and the proceeds to crash when I plug in the second. The display becomes pixilated and hangs until I remove one of the displays. This does work if I use two MDP adapters though... Can any one help as to why I cant mix the 2 and only use 2 MDP adapters?
