Connecting Video source devices
You can connect your projector to various Video source devices that provide 
any one of the following output sockets:
„HDMI
„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 avail-
ability of matching terminals on both the projector and the Video source 
device as described below:

Connecting an HDMI source device
Examine your Video source device to determine if it has a set of unused 
HDMI output jacks 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 HDMI source device:
1. Take an HDMI cable and connect one end to the HDMI output jack of the 
HDMI source device.
2. Connect the other end of the HDMI cable to the HDMI jack on the 
projector.
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 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 cable (with a D-Sub type connector) to the 
VGA1/YPbPr or VGA2/YPbPr 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. 
						

							EN-23
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 21 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 21 for details.
