Hot Issues   Jittery or Blurry Video with Power Macintosh 5500/6500 - 2


               Jittery or Blurry Video with Power
               Macintosh 5500/6500
               If the display exhibits jittery or blurry video when
               connected to a Power Macintosh 5500 or 6500, suspect the
               computer, not the monitor.

               Video jitter affects monitors connected to computers having
               a 225 or 250 MHz logic board. Jitter is evident where the
               pixels shimmer or jump at the edges of the screen, windows,
               or dialog boxes.

               Blurry video is seen as a fuzzy image over the entire screen
               on monitors set to resolutions of 832x624 and higher.
