Power Macintosh 7500 & 8500: Using a DAV Card (12/95)
I have a Power Macintosh 8500 computer with a third-party DAV (Digital Audio/Video) card installed. Ever since installing the DAV card the images on the screen appear distorted.
Apple is aware of and has resolved this DAV issue, which affects a small number of Power Macintosh 7500 and 8500 computers. For assistance resolving this issue, contact an Apple-authorized service provider.
