I'm running a Mini headless and controlling it via Screen Sharing. The only display resolutions I can select are : 1680x1050, 1280x1024, 1024x768, 800x600. When I connect a real display to it I get the full list, including the one that is the best for my MBA - 1440x900. Is there any way I can fool the Mini into displaying other/any resolution ? I've looked at Switch ResX but it doesn't work in Lion and Display Maestro is no use. Ideas ? PS I got Switch ResX to work, but it is no use either.
