Subject: Computer DVD video tearing on Epson Projectors

This bulletin was created to inform you of DVD video tearing on Epson projectors manufactured
prior to June 1998.

Models affected:

ELP-3000 ELP-3300 ELP-3500 PowerLite-5000
PowerLite-7000 PowerLite-5000XB PowerLite-7000XB PowerLite-7300

Description of artifact:

When playing high image contrast, fast-action DVD movies, a very thin horizontal break can occur
in the image. The line-tear is very difficult to see if the viewing environment is moderately or
brightly lit. Most viewers will not notice it. This line-tear can occur at the top, middle or bottom of
the screen as the movie continues to play. The tearing occurs about every 5 to 8 minutes of play
and can be seen for the duration of the movie. The break can also appear to travel vertically over
time because of timing differences between video frame rates and projector refresh cycles. The
artifact only occurs when playing movies from a Computer DVD player through the VGA port.
There is no video tearing of the same motion picture through the S-Video, Composite or
Component input ports on the projector. The artifact appears only in the video display. The audio
track is unaffected. The issue is not dependent on PC or Mac hardware platforms, operating
system or DVD player software.

Reasons:

Digital video playback through computers was not prevalent until the mass production of
Computer DVD players. With the incorporation of NTSC video frames embedded into RGB
computer video signals, synchronization limitations (frame shift) were encountered. In June 1998,
Epson incorporated frame synchronization circuitry for future projector models to eliminate the
artifact.

Resolution: Because the introduction of Computer DVD playback occurred after the manufacture
of the mentioned projectors, Epson has no plans to replace or upgrade the models specified.
