Connecting a composit e 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.
3. If you wish to make use of the projector  (mixed mono) speaker in your presentations, 
take a suitable audio cable and connect one end of the cable to the audio output socket 
of the device, and the other end to the  AUDIO IN socket of the projector.
4. If you wish, you can use another suitable audio cable and connect one end of the cable  to the  AUDIO OUT  socket of the projector, and the other end to your external 
speakers 
Once connected, the audio can be controll ed by the projector On-Screen Display 
(OSD) menus.
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 15  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.
• 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 15  for details.

Selecting the aspect ratio
The aspect ratio is the ratio of the image  width to the image height. Most analog TV and 
computers are in 4:3 ratio, which is the defaul t for this projector, and digital TV and DVDs 
are usually in 16:9 ratio.
With the advent of digital signal processing,  digital display devices like this projector can 
dynamically stretch and scale the image output to  a different aspect than that of the image 
input signal. 
To change the projected image ratio (n o matter what aspect the source is):
1. Press  MENU/EXIT  on the projector or  MENU on the remote control and then press 
/  until the  DISPLAY menu is highlighted.
