I did just a bit of searching and found some cable answers but none that I thought fully answers my question, which is two-fold: 1. I am ordering a new 27" iMac but want to connect my Dell 30" monitor as a second monitor. I assume the iMac does not come with the necessary cable, but I'm not sure which one to buy. The Dell monitor is digital with a 2560x1600 resolution. 2. Would that same cable be able to connect a 2010 model Macbook Pro to the new iMac and/or the Dell? The one area I feel Apple needs help is the multiple monitor situation. For years I have run laptops with 2-3 external monitors... I find myself having to go back to 2 monitors with either setup unless I buy some 3rd party hardware or shell out for a Mac Pro.
