I've just bought a 22" Acer monitor which supports as its highest resolution 1680 x 1050. My first generation macbook with the GMA 950 graphics should theoretically be able to support this right? Yet I can't seem to get it to display at that resolution. The resolution I have it at now is 1280 x 960, and the only other resolution it's showing as available is 1280 x 1024. Any ideas on how to get this working? I've tried clicking Detect Displays and restarting the macbook, both to no avail.
