Logan: 27 inch 3 monitor setup. Display port to DVID converter?

Hey guys, I would like to ask you a quick question in regards to Korean Monitors.

I recently purchased 3 QNIX 27" 2560x1440 QHD PLS Monitors (they should arrive this week) and I was wondering if you guys could advise me on what Display port to DVID converter to get (the one that you used in your own setup in the videos) so that I can run 3 monitors?

I will be running them off 2 ASUS Radeon R9 280X in Crossfire.

Reason I ask is I cannot seem to find some valuable information. And I know a lot of the just don't work. I know you have done this successfully in some of your vids and I am hoping you can help me with what sort of Display port to DVID converter  you used.

Thank You
