Me mate just got a Mac mini with Panther installed. He bought a nice Sony lcd with it. Took it home. Plugged it all in, it works fine. But then this funny problem develops. Whenever you'd minimize a window into the dock it the screen would fade into blue then back again. A strange problem which got gradually worse until the screen would fade into blue momenterily every five seconds. I tried to reinstall OS X, update Panther, no joy. The screen looked fine when you booted off a CD, but whenever the HD was involved its would relentlessly fade into blue. Ready to take it back to Apple, I tightened up the monitor cable screws (its an analogue monitor BTW) and the VGA to DVI converter. Then it worked fine. Can anyone explain? It looked like a software problem when it faded into blue. Why would a loose cable cause OS X to do thiS?
