Hello All - I've been going around in circles with this topic for the last few hours and need a definitive answer. I recently bought a widescreen Dell Ultrasharp that has an HDMI, DVI-D, DisplayPort & Mini-DisplayPort connection capability. My Macbook Air on the other hand only has a Thunderbolt Port Out. The resolution on the Dell is 2560x1080. My question is very simple: What is the best/easiest way to connect my Macbook Air with a Thunderbolt Port to my Dell and realize the full resolution on the Dell monitor. I'm reading that I can connect with a mini-display port (hooked up in the macbook air's thunderbolt port) to a dual-link dvi-d. But these cables are very expensive. Can I use a mini-display port to mini-display port connection and still realize the full resolution of the Dell at 2560x1080? Thanks!!
