Hello, I recently (in December) got an MBA (Model Identifier MBA2,1) 2.13 GHz. According to spec. this device should display 2560x1600 on an external screen. But I never get to choose this resultion in the display settings. All I get is 2560x800. Any ideas what could be done to get the MBA to show me all its possible screen resolutions up to and inclusing it's full resolution?
