Dear members, i have read several forums and came across post's with people that have the same issue as me but unfortunately they've all fixed the problem but i can't seem to fix it. This is the problem. I connect my MBP with my Cinema display. The max resolution i can choose is 1280x800 which is logical because that is the highest resolution the MBP support (i believe). However, it is possible to use the resolution of my Cinema Display (2560x1600) but there are a few conditions to it. - Macbook has to be power connected - ONLY the cinema display can be used, so no duplicated screens allowed - The macbook must be in sleep mode and awaken with an external keyboard. You should now be able to choose a resolution of 2560x1600. I have read several forums and this really did work for people! But somehow my max resolution remains 1280x800 Im using a MBP 13inch late 2009 and have it connected to the screen with a mini displayport to DVI adapter. Please help!
