To transmit video signals through the S-Video-out jack, you
need a standard S-Video cable, available from most computer
or electronics retailers.
To connect the S-Video cable:
1. Plug either end of the S-Video cable into the notebook
S-Video-out jack.
2. Plug the other end of the cable into the S-Video-in jack (not
the S-Video-out jack) on the external device.
