What cable should I buy to hook this monitor to my Macbook Pro?

I have to agree with CloneRanger. I'm certain you need a Mini-DisplayPort Male to DVI-D Female Digital Video Adapter like this one, a href="http://www.trianglecables.com/mini-displayport-male-to-dvi-d-female-digital-video-adapter-connects-macbook-macbook-pro-macbook-air.html" rel="nofollow"http://www.trianglecables.com/mini-displ…/a I just bought some computer cables from that site a few days ago and they are actually still running 15% off all their cables, which should apply to that adapter. You'll end up saving a few more dollars off it. Hope this helps!
