    What exact Mac with what GPU do you use?
    What connection do you use to what external display?

    Could be the video card or it could be a driver that is having issues. Have you tried reinstalling the OS first? I would try that and see if the issues goes away before heading to the store.

    What monitor are you using? Are you using any adaptors to convert the MP output to whatever will fit in the monitor?

    If you rang the AppleCare line the first thing they will tell you to do is a SMC and PRAM reset - search the forum for info on how to do those before you go to the effort of reinstalling OSX.

    If you bought the MP new, you will be covered under AppleCare too, so don't worry unless this is costing you money because of being a business machine.

    looks like a GPU problem, if you are using the DP connectors and no converters anywhere, it is most likely the card itself.
