Sorry if this is an old question, but I seem to have a strange problem. Basically the external monitor works when the Macbook lid is open - but if I close the lid, putting the Macbook to sleep, then wiggle the mouse to awaken the Macbook, the external monitor displays an "Out Of Range" error. I can't see why it would work one moment and not the next depending whether the lid is closed or open - I've not had this problem before. Any pointers gratefully received. Thanks, Andy a.k.a.
