    I am setting up a new 17 inch macbook pro for a friend. He uses a 24 inch LCD external monitor so we purchased the mini display port to dvi adapter (as opposed to the mini display port to dual link dvi adapter for 30 inch monitors). However, I am at home setting up his computer using my external monitor which is the 30 inch dell monitor. For some reason, the maximum resolution I can get is 1280x800 on the external 30 inch monitor. I figured I should at least be able to get 1920x1200 resolution, right?? Does anyone know what may be going on here. I know you're able to switch between video cards on the unibody macbook pros, how do I do that as well? Thanks for any help!

    The maximum resolution of the 30" ACD when connected to a single link DVI connection is 1280 x 800 so I guess the Dell could be the same?

    Thanks, That makes sense now why dual link is 2560x1600....I didn't think about that.
