I am about to calibrate a new Dell 2707WFP LCD moniter with SpyderPro 2.2. If I use the DVI connection, I do not have access to the front controls on the moniter such as brightness and contrast. I only have access to these when I use the analog connection. Since I want to calibrate the moniter with my SpyderPro 2.2, am I better using the analog or DVI connection? Thanks.
