The line-tear is very difficult to see if the viewing environment is moderately orbrightly lit. Most viewers will not notice it. This line-tear can occur at the top, middle or bottom ofthe screen as the movie continues to play. The tearing occurs about every 5 to 8 minutes of playand can be seen for the duration of the movie. The break can also appear to travel vertically overtime because of timing differences between video frame rates and projector refresh cycles. Theartifact 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 orComponent input ports on the projector. The artifact appears only in the video display. The audiotrack is unaffected. The issue is not dependent on PC or Mac hardware platforms, operatingsystem or DVD player software.Reasons:Digital video playback through computers was not prevalent until the mass production ofComputer DVD players. With the incorporation of NTSC video frames embedded into RGBcomputer video signals, synchronization limitations (frame shift) were encountered. In June 1998,Epson incorporated frame synchronization circuitry for future projector models to eliminate theartifact.Resolution: Because the introduction of Computer DVD playback occurred after the manufactureof the mentioned projectors, Epson has no plans to replace or upgrade the models specified.
