Hi All, I have recently bought an 11" Air and have borrowed a friends 30" cinema display to decide whether I want to buy a big screen (I am now saving for a 27") I'm due to give it back soon so got a MDP to VGA adaptor today for another 19" screen that I have. So after checking the 19 inch works ok, I went back to the 30" cinema and now the view has changed. All resolutions are set to maximum, everything is bigger than before. When plugging in before all windows were the size of my 11" display. Now I have to have them full screen to see the full page and it"s driving me mad! I checked that i'm not zoomed and resolutions are set at maximum for the cinema display. What have I done wrong?? I'm guessing it's something really simple, please help if you can.
