Connecting Video source devices

This section describes how to connect the projector to Video source devices using video cables. Video cable connections are recommended for Video presentations.

This projector also supports data (graphic) "PC" connection using wireless function. Wireless connection is not recommended for Video presentations. See "Wireless connection (optional)" on page 22.

You can connect your projector to various Video source devices that provide any one of the following output sockets:

•DVI

•Component Video

•S-Video

•Video (composite)

You need only connect the projector to a Video source device using just one of the above connecting methods, however each provides a different level of video quality. The method you choose will most likely depend upon the availability of matching terminals on both the projector and the Video source device as described below:

Best video quality

The best available video connection method is DVI. If your source device is equipped with a DVI socket, based on the type of DVI connector you have, you can enjoy digital or high-end analog video quality.

See "Connecting a DVI source device" on page 26 for how to connect the projector to a DVI source device and other details.

If no DVI source is available, the next best video signal is Component Video (not to be confused with composite Video). Digital TV tuners and DVD players output Component Video natively, so if available on your devices, they should be your connection method of choice in preference to S-Video or (composite) Video.

See "Connecting a Component Video source device" on page 27 for how to connect the projector to a component video device.

Better video quality

The S-Video method provides a better quality analog video than standard composite Video. If you have both composite Video and S-Video output terminals on your Video source device, you should elect to use the S-Video option.

See "Connecting an S-Video source device" on page 29 for how to connect the projector to an S-Video device.

Least video quality

Composite Video is an analog video and will result in a perfectly acceptable, but less than optimal result from your projector, being the least video quality of the available methods described here.

See "Connecting a composite Video source device" on page 30 for how to connect the projector to a composite Video device.
