I just ordered a new 15" mbp, and a 24" Dell ultrasharp with display port. I am a bit confused about the cables I need. The Dell monitor arrived with some interesting looking cables that look like they might be displayport - but the mbp looks much smaller (mini). I have searched amazon and apple stores looking for the cable or adapter that I need, but I am not clear. I assume I can get the mini displayport to dvi or HDMI, but that seems silly when my monitor supports displayport ... Any suggestions?
