I currently run a Dell 2007WFP 20" monitor with my MacPro 2.66GHz which I use for video editing. I want to buy second monitor to have a dual setup, but am having trouble finding the right one. My first question is, should I get a matching 20" or is it ok to go a bit wider? I was looking at the Dells but it appears that most of them now have TN panels, which I wanted to stay away from. Any info would be greatly appreciated.
