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. 
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)

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 

 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 

 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 select to use the S-Video option.
See 

 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 

 for how to 

connect the projector to a composite Video device.
