							Operation 25
Switching input signal
The projector can be connected to multiple devices at the same time. However, it can only 
display one full screen at a time. 
Be sure the Quick Auto Search function in the SOURCE menu is On (which is the default of 
this projector) if you want the projector to automatically search for the signals.
You can also manually cycle through the available 
input signals.
1. Press SOURCE on the projector or remote 
control. A source selection bar displays. 
2. Press  /  until your desired signal is 
selected and press MODE/ENTER.
Once detected, the selected source information 
will display on the screen for seconds. If there 
is multiple equipment connected to the 
projector, repeat steps 1-2 to search for another 
signal.
• The brightness level of the projected image will 
change accordingly when you switch between 
different input signals. Data (graphic) PC 
presentations using mostly static images are generally brighter than Video using mostly 
moving images (movies).
• The input signal type effects the options available for the Picture Mode. See Selecting a 
picture mode on page 28 for details.
• The native display resolution of this projector is in a 4:3 aspect ratio. For best display 
picture results, you should select and use an input signal which outputs at this resolution. 
Any other resolutions will be scaled by the projector depending upon the aspect ratio 
setting, which may cause some image distortion or loss of picture clarity. See Selecting 
the aspect ratio on page 27 for details.
Adjusting the projected image
Adjusting the image height
The projector is equipped with 1 adjuster foot. This adjuster changes the image height. To 
adjust the projector:
1. Screw the adjuster foot to adjust the image 
height.
To retract the foot, screw the adjuster foot in a 
reverse direction.
If the projector is not placed on a flat surface or the 
screen and the projector are not perpendicular to 
each other, the projected image becomes 
trapezoidal. To correct this situation, see 
Correcting keystone on page 26 for details.
• Do not look into the lens while the lamp is on. The strong light from the lamp may cause 
damage to your eyes.
• Be careful when you screw the adjuster foot as it is close to the exhaust vent where hot air 
comes from.

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.

							Operation 282.
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. Full Screen: Any types of resolution always fill the 
whole screen.
4.4:3: 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.
5.16:9: 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
The projector is preset with several predefined 
picture modes so that you can choose one to suit 
your operating environment and input signal 
picture type.

sRGB compatible and properly calibrated camera, and for viewing PC graphic and 
drawing applications such as AutoCAD.
4.Movie mode: Is appropriate for playing colorful movies, video clips from digital 
cameras or DVs through the PC input for best viewing in a blackened (little light) 
environment.
5.User mode: Recalls the settings customized based on the current available picture 
modes. See Setting the User mode on page 29 for details.

Using Wall Color
In the situation where you are projecting onto a colored surface such as a painted wall which 
may not be white, the Wall Color feature can help correct the projected picture’s color to 
prevent possible color difference between the source and projected pictures.
To use this function, go to the DISPLAY > Wall Color menu and press  /  to select a 
color which is the closest to the color of the projection surface. There are several 
precalibrated colors to choose from: Light Yellow, Pink, Light Green, Blue, and Blackboard.
Fine-tuning the image quality in user modes
According to the detected signal type, there are some user-definable functions available 
when User 1 or User 2 mode is selected. You can make adjustments to these functions based 
on your needs.
Adjusting Brightness
Highlight Brightness in the PICTURE menu and adjust the values by pressing  / on the 
projector or remote control.
The higher the value, the brighter the image. And lower 
the setting, darker the image. Adjust this control so the 
black areas of the image appear just as black and that 
detail in the dark areas is visible.
Adjusting Contrast
Highlight Contrast in the PICTURE menu and adjust the values by pressing  / on the 
projector or remote control.

projector or remote control.
The higher the value, the more reddish the picture becomes. The lower the value, the more 
greenish the picture becomes.
