Cause There may be too many video devices between your video source and destination, or one or
more of the video devices may be degrading the quality of the video signal. Demodulators,
long cables, cable extensions and improper connections can all affect video signal quality.
Solution If your video equipment supports it, use S-video connections. For more information, see
“Connection setup”, page 26.
Solution Try changing one or more video devices.
Solution If possible, use fewer connections. For example, don’t use cable extensions.
Cause The image settings on your TV may need adjusting.
Solution Some TVs have an aperture control sometimes called PICTURE . Lowering this setting may
reduce this problem. Reducing your TV’s brightness setting may also improve image quality.
For more information, see your TV manual.
Problem Can’t record video with a VCR
Cause
The video source may be copy protected. Your Matrox product may not let you make copies
of copy-protected video. (Some video sources let you make a copy of a video, but you may
not be able to make a copy of that copy.)
Solution To get copies of a copy-protected video, contact the vendor of the video.
