You should always use the S-Video ports that are on the AV card, since the S-Video port on the AudioVision 14" Display is currently not supported. Page 22 of the AudioVision Display owners guide incorrectly states that S-Video Pass Through is supported.
The same holds true when the AudioVision monitor is connected to a Quadra 660AV or the Quadra 840AV, S-Video is only supported through the card itself and not the monitor.
Article Change History:
10 Feb 1995 - Noted that S-Video is only supported on the card.
13 Oct 1994 - Added keyword; made minor technical updates.
