    I recently purchased an acer 23" widescreen monitor and I'm using it as an external monitor for my 13" unibody macbook. Im having an issue with colors on the external monitor, blacks and dark greys displaying but have constantly and fast moving red dots moving around in them, not sure what to do about this, could I be missing a setting within display settings? The monitor is hooked up via DVI btw.

    Try calibrating the monitor. System Preferences -> Displays -> Color -> Calibrate

    As for the dots, make sure you have a good properly shielded cable. Cheap POS monitor cables are notorious for ghosting and pixel crawl in my experience (mostly on VGA connections, but I guess a crappy cable could be THAT bad and mess up digital DVI even)
