    I'm working with a Mac Pro (2x3 GHz Dual-Core Intel Xeon, 4 GB RAM) and a dual 23" monitor setup. Quite recently the second monitor stopped responding, after disconnecting everything, moving, and reconnecting. (Everything was boxed lovingly in its original packaging and moved by gentle movers.)

    It isn't the monitors — both work fine in the first monitor port. The computer recognizes there is a second monitor attached, allowing me to access Arrangement options under System Preferences > Displays.

    The power light on the second monitor comes on, blinking in the following manner (if it were Morse Code): dot dash dot....(then it is dark for about four seconds before repeating the same blinking sequence). It appears to have some sort of meaning.

    Any ideas? Is there a way to reset this? Thanks.

    Thanks for that link, I don't know how I missed it. I have two Mac Pros, both with dual setup — the other has 20" monitors. A power adaptor on each got switched in the move.

    Thanks again!
