Hello Folks, While you're getting info on m's video problem, please also consider this. I'm using a 550 mhz G4 Ti book. The computer boots fine but the display shows only a ghost of an image - it kind of like it's five stops underexposed. Of course I have tried all brightness and contrast controls available to me – I think. Using an external display - everything is fine. Anyone with suggestions please write. Thanks Ptah -------------- next part -------------- An HTML attachment was scrubbed... URL: http://listserver.themacintoshguy.com/pipermail/titanium/attachments/20061213/17c2d69d/attachment-0001.html
