Video output with DP...Which solution??

[p.pan]

Hi,

I was just thinking to buy a video card from Blackmagic:
PCIe DeckLink Mini Monitor 145U$...
But I saw didnt work with DP.....

My Setup:
Macpro 5.1 (Middle 2010).
12 Cores, 64G ram, on Sierra.
Graphic cards: Radeon HD5770.

I will work mostly for dubbing, sound design and music for movie.
My need:
1x Monitor 55" (for the video with a good quality for the actors).
2x Monitors 24"
One for the artistic director (With the video).
And one for the sound engineer.

Do I need to change my Graphic cards??
What is the solution??
Did MOTU have a solution?
Because everybody told me I must to go to Protools.....
I try to resist.....I like My DP..

Thanks a lot for your answer.
