I have a 15" unibody Macbook Pro, and just purchased a 22" Dell Ultrasharp Monitor- 2209WA. I obviously am going to have to get a Mini Displayport adapter, but which one is better? VGA? DVI? Am I going to have any problems with this setup? I've read of people's external displays not working well with the MBP. What should I expect? Thanks. P.S. I searched but did not find an exact conclusive answer.
