Sony PCG-GR300 Manual

You can connect an audio-video (AV) device, such as a TV or a VCR, to the optional port replicator or the notebook. 

 

Prior to attaching a video device, unplug the connecting cable from the Monitor jack. 

To connect an AV device to the optional port replicator, use the S-video jack and the Headphone jack, which require a
S-video cable and an audio cable. To connect an AV device to the notebook, use the AV out jack, which requires an
audio-video cable. Remember to switch the TV input channel to external input and set up the TV configuration system. See 

 for more information. 

If you connect an AV device to the S-video jack, you must use the Audio (L) and the Audio (R). Also, the S-video jack and the
AV out jack are not designed to be used simultaneously. If you connect cables to both jacks, only the S-video jack will
function.
