Screen went fuzzy, static

[suckatcomputers]

I was just browsing the internet and checking my e-mail like i do everyday, and all of a sudden my screen went completely fuzzy, static like TVs do when you unplug the antenna.

I pushed the power button on the macmini and my screen came back up.

Has this happened to you? What could this have been? Everything is fine now but I still have my warranty and wondering if I should be concerned about this?

I don't even have guess on what could have caused this...

Yes this has happened to me. I usually power cycle my monitor and its back to normal. I think this has something to do with video drivers, come to think of it I dont think it has happened since the last OSX update.
