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 20  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 20  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 21  for how to connect the 
projector to a composite Video device.

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 VGA (D-Sub) to HDTV (RCA) cable, Component Video cable or a  Component Video to VGA (D-Sub) adaptor 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. If you are using the VGA (D-Sub) to HDTV (RCA) cable and the Component Video 
to VGA (D-Sub) adaptor, connect the other end of the cable (with a D-Sub type 
connector) to the 
Computer in 1 or Computer in 2 socket on the projector. If you 
are using the Component Video Cable, connect the other end of 3RCA type 
connectors to the 
Y Cb/Pb Cr/Pr sockets on the projector.Important
„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.

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.

Important
„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 19  for 
details.
Connecting a composite Video source device
Examine your Video source device to determine if it has a set of unused composite 
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 composite Video source device:
1. Take a Video cable and connect one end to the composite Video output socket of 
the Video source device.
2. Connect the other end of the Video cable to the Video socket on the projector.Important
„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.
„You need only connect to this device using a composite Video connection if 
Component Video and S-Video inputs are unavailable for use. See 
“Connecting Video source devices” on page 19  for details.
