I have 2 x 24 inch Dell 2408WFP monitors and would like to hook them up to a Mac Pro I am about to buy. Mac Pro is the 2.26 8-core with NVIDIA GeForce GT 120 512MB The dell 2408WFP have DVI ports and HDMI. An Apple chat sale peerson said there was no cable that apple supplies that works for me. IS he mistaken? What cables do I need to make both monitors work with the Mac Pro? Thank you in advance!
