    I'm not sure what happened, but my MacBook Pro has suddenly stopped auto-detecting when a new DVI cable is attached. The monitor is turned on and the right input is selected, but the only way I can get it to work is if I go into the System Preferences, Displays, and then click the Detect Displays button. Does this sound like a software problem or a hardware problem? I'd really appreciate anybody's help.. It's driving me nuts! Thanks!

    Happens to me as well. Are you using the Penryn MBP?

    I'm using the latest 15" MBP, so yes, I believe that's the Penryn. I don't get it though - it was working two weeks ago, and now it's not.

    Hmmm, never seen that issue on my MBP but you can cut some steps until you find a solution by checking the Show displays in menu bar option in sys prefs. This way you can just select detect from the menu bar.

    Cheers,
