    The title says it all really... Quite a simple problem that I can't find any answer to!

    I've hooked up my 30" Apple Cinema Display to the new iMac 27" and the highest resolution I'm getting as an option is 1280x800... The iMac correctly detects the ACD as a Cinema HD display but limits my resolution. Why oh why?!

    *sigh*

    If anyone could help me out here it'd be much appreciated.

    RGunner is right. You will get the full resolution when you use the (expensive) mini displayport to dual link DVI adapter.
