    hmmm interesting, I have not had that problem with my MPG4 matter of fact I replaced the old DELL monitor I had with one that was supposed to be used for my G/Fs PC but it [PC] would not take it!? I thought that the PC might have died so I tried it on my MPG4 and VIOLA works like a dream!!
    Have you tried a different monitor to see if that might be the problem?? If not try looking around the systems preferences under displays from here you can change the settings of your monitor. I'm not 100% sure if this will help resolve your situation but it might be a start.
    Hopefully some one will have an answer to your problem! Good luck!!!

    does your monitor have a usb hub that your keyboard/mouse is connected to?
