FYI.

Running on a pc here with a 6970 card triple head. 

I bought this. 


Then hooked two monitors up via the 2 DVI ports on the back of the card, an= d connected the third monitor using that adapter to DVI. 
WORD OF WARNING:
Depending on how you setup the eyefin= ity/ desktop layout settings, for 3 screens you'll have screen tearing on ei= ther the monitor you use the adapter for, or the other two. ATI cards do not= have a secondary frequency clock adjustment for multiple monitors from what= I've read.  In other words, either your adapter fed monitor will be at= a "wrong refresh rate" to try matching the other two, or the other two will= be the wrong ones to try matching the displayport one.

It's not horrible tearing or anything, but there is a noticeable l= ine where when dragging windows around or watching video on the screen it wi= ll be a fraction of a second behind the top portion of the screen. Here's a v= ideo of the extent of the tearing while dragging a window around. 

htt= p://www.youtube.com/watch?v=3DsaG2mr6qM_8

Mine,= the line where the tear happens actually slowly moves down the screen, so i= t's not like it was avoidable for certain uses. 

I set mine up with the Adapter fed screen being the incorrect frequency, wh= ich allowed me to put that one on my right, like in that video, and use it f= or documents, photoshop, or whatever, while I work on the middle monitor wit= h most of my tools and timeline, and my left monitor has the comp viewer and= effects palette along the vertical near the middle monitor. 

As far as I know, the only way not to get this to happen is t= o have a card with enough MDP or DP jacks to feed your monitors correctly, o= r to buy a "plug into the wall" powered hub that's like $130 that feeds 3 mo= nitors via one MDP off of the back of the card.  

<= div>Hope this helps.
