I have a Dell 27" 2707WFP and a Viewsonic 27.5" VX2835WM both from Costco. I'm comparing these monitors before deciding which one to keep and which to send back. If anyone would like me to run some tests on them, let me know which tests and how to run them and I'll try to report back here. I will only have them for a few days however so act fast if you want me to run something....
