Hi, I have my MacBook Pro (Intel Core 2 Duo, 2 GB Memory, 15" screen) connected to an external monitor via the DVI port. What can I do to make sure the external monitor is running at top quality with respect to brightness, color, etc. I *think* it is OK, but sometimes I think it is a tad blurrry -- but I don't know if my mind is playing tricks on me. Is there a tool or something I can use? I have a 22" LG Flatron widescreen -- L226WTQ Thanks.
