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.
The final connection path should be like that shown in the following diagram:
• 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 18 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 default 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 (no matter what aspect the source is):
1. Press Menu/Exit and then press  /  until the DISPLAY menu is highlighted.
2. Press
  to highlight Aspect Ratio.
3. Press  /  to select an aspect ratio to suit the format of the video signal and your 
display requirements.
About the aspect ratio
In the pictures below, the black portions are inactive areas and the white portions are active 
areas. OSD menus can be displayed on those unused black areas.
1.Auto: Scales an image proportionally to fit the 
projectors native resolution in its horizontal width. 
This is suitable for the incoming image which is 
neither in 4:3 nor 16:9 and you want to make most 
use of the screen without altering the images aspect 
ratio.
2.
Real: The image is projected as its original 
resolution, and resized to fit within the display area. 
For input signals with lower resolutions, the 
projected image will display smaller than if resized 
to full screen. You could adjust the zoom setting or 
move the projector towards the screen to increase 
the image size if necessary. You may also need to 
refocus the projector after making these 
adjustments.
3.4:3: Scales an image so that it is displayed in the 
center of the screen with a 4:3 aspect ratio. This is 
most suitable for 4:3 images like computer 
monitors, standard definition TV and 4:3 aspect 
DVD movies, as it displays them without aspect 
alteration.

							Operation 304.16:9: Scales an image so that it is displayed in the 
center of the screen with a 16:9 aspect ratio. This is 
most suitable for images which are already in a 16:9 
aspect, like high definition TV, as it displays them 
without aspect alteration.
Optimizing the image
Selecting a picture mode
