This just started yesterday and it has occurred an additional 3 or 4 times now. Several pixels on my display will change to white or purple, and soon enough everything gets severely distorted. Sleeping then waking the comp brings everything back to normal, but sooner or later the problem comes back. Does anyone know if this is a problem with the monitor or a problem with my G4? I don't have any interface haxies installed or anything, and haven't installed anything else for that matter, just Software Update stuff and updates to things like Adium and Google Earth and other common apps. The monitor is connected to the comp using VGA. I've attached a screenshot. Thanks anybody!
