lish 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:
•
HDMI
• DVI-D
• 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 HDMI. If your source device is equipped with a HDMI socket,
you can enjoy uncompressed digital video quality.
See
"Connecting a HDMI source device" on page 19 for how to connect the projector to a HDMI source device
and other details.
If no HDMI source is available, the next best video signal is DVI-D. If your source device is equipped with a DVI-
D socket, you can enjoy digital video quality.
See
"Connecting a DVI-D source device" on page 20 for how to connect the projector to a DVI-D source device
and other details.
If no DVI-D 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 21 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.
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 an S-Video or a composite Video source device" on page 22 for how to connect the projector to
an S-Video or Video device.
Connecting Audio
The projector has built-in mono speakers which are designed to provide basic audio functionality accompanying
data presentations for business purposes only. They are not designed for, nor intended for stereo audio
reproduction use as might be expected in home theater or home cinema applications. Any stereo audio input (if
provided), is mixed into a common mono audio output through the projector speakers.
