|When you use a S-Video cable, you must also set the video source on whatever you're connecting it to , to the appropriate input. E.g. On a TV, to an input other than the TV tuner - Video, or Video 1, or Video 2, or S-Video, etc. |
A S-Video connection (or a composite video connection) from your video adapter has TV Out output - it's processed through a chip on the video adapter to conform to relatively ancient TV display standards, and the resulting display on the TV does NOT look as good as the display on your monitor. If the TV has a a VGA port, DVI port, or a HDMI port, connecting a cable to any one of those from your video adapter yields a much better looking display on the TV.
