    Hi,

    My friend's external screen is doing this whenever he wakes the computer (brand new aluminium MacBook) up from sleep - the screen on the laptop is fine. The only way he has found to resolve it is to reboot the computer. Is anyone else having this problem and have they found a solution to it? The monitor and micro dvi-dvi adaptor are also brand new. The problem cannot be reproduced when the same monitor is plugged into my WhiteBook.

    He has tried everything suggested in this thread on the Apple support forum.

    no, there is no solution for now. The easy way to fix it is to force the displays to sleep, this can be achieves by pressing

    CONTROL+SHIFT+EJECT

    It will sleep the monitors, and then you wake them up with mouse movement or keyboard and it will wake up properly.

    Some people also plug/unplugg the mini displayport adapter, I dont cause I'm afraid of wear off, so the best solution is to sleep the monitors with the 3 key combination i mentioned.

    Rumors say that apple has acknowledged the problem and a fix is on the way.

    Some blame the 10.5.4 to 10.5.5 update as the origin of this problem.

    Good luck

    Infact, there is a solution.

    It happens with me as well - the exact same problem. I just turn the external monitor off, unplug the minidisplay port cable and then wait a few secs and put it back in. Switch the monitor back on, and there ya go ;)
