Connecting Video source devices
You can connect your projector to various Video source devices that provide any one of the 
following output sockets:
• 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 Component Video (not to be confused with 
composite Video). Digital TV tuner and DVD players output Component Video natively, so 
if available on your devices, this should be your connection method of choice in preference 
to (composite) Video.
See Connecting a Component Video source device on page 23 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 24 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 25 for how to connect the 
projector to a composite Video device.
Connecting Audio
The projector has a built-in mono speaker which is designed to provide basic audio 
functionality accompanying data presentations for business purposes only. It is not designed 
for, nor intended for stereo audio reproduction use as might be expected in home theatre or 
home cinema applications. Any stereo audio input (if provided), is mixed into a common 
mono audio output through the projector speaker. 
If you have a separate sound system, you will most likely want to connect the audio output 
of your Video source device to that sound system, instead of to the mono audio projector. 
The audio connections illustrated in the following sections are provided for informational 
purposes only. You need not connect audio to the projector if there is an alternate sound 
system available, or if audio is not required.

Connecting a Component Video source device
Examine your Video source device to determine if it has a set of unused Component Video 
output sockets available: 
• If so, you can continue with this procedure.
• If not, you will need to reassess which method you can use to connect to the device.
To connect the projector to a Component Video source device:
1. Take a Component Video to VGA (D-Sub) adaptor cable and connect the end with 3 
RCA type connectors to the Component Video output sockets of the Video source 
device. Match the color of the plugs to the color of the sockets; green to green, blue to 
blue; and red to red.
2. Connect the other end of the Component Video to VGA (D-Sub) adaptor cable (with 
a D-Sub type connector) to the D-SUB/COMP IN socket on the projector.
3. If you wish to make use of the projector (mixed mono) speaker, take a suitable audio 
cable and connect one end of the cable to the audio output socket of the computer, 
and the other end to the Audio socket of the projector.
The final connection path should be like that shown in the following diagram:
If you connect the projector to a High Definition TV (HDTV) tuner, the follow ing standards 
are supported:
• The projector is only capable of playing mixed mono audio, even if a stereo audio input is 
connected. See Connecting Audio on page 22 for details.
• Component Video is the only video output that delivers native 16:9 aspect ratio picture.
• If the selected video image is not displayed after the projector is turned on and the correct 
video source has been selected, check that the Video source device is turned on and 
operating correctly. Also check that the signal cables have been connected correctly.
• 480i • 480p
• 576i • 576p
• 720p (50/ 60 Hz) • 1080i (50/ 60 Hz)

Connecting an S-Video source device
Examine your Video source device to determine if it has an unused S-Video output socket 
available: 
• If so, you can continue with this procedure.
• If not, you will need to reassess which method you can use to connect to the device.
To connect the projector to an S-Video source device:
1. Take an S-Video cable and connect one end to the S-Video output socket of the Video 
source device.
2. Connect the other end of the S-Video cable to the S-VIDEO socket on the projector.
The final connection path should be like that shown in the following diagram:
• The projector is only capable of playing mixed mono audio, even if a stereo audio input is 
connected. See Connecting Audio on page 22 for details.
• If the selected video image is not displayed after the projector is turned on and the correct 
video source has been selected, check that the Video source device is turned on and 
operating correctly. Also check that the signal cables have been connected correctly.
• If you have already made a Component Video connection between the projector and this 
S-Video source device using Component Video connections, you need not connect to this 
device using an S-Video connection as this makes an unnecessary second connection of 
poorer picture quality. See Connecting Video source devices on page 22 for details.
