Selecting the aspect ratio
The aspect ratio is the ratio of the image width to the image height.
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):
• Using the remote control
1. Press ASPECT to show the current setting.
2. Press ASPECT repeatedly to select an aspect 
ratio to suit the format of the video signal and 
your display requirements.
•Using the OSD menu
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 or 
vertical 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 adjusents.
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.

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

when User 1 or User 2 mode is selected. Based on your needs, you can make adjusents 
tothese functions by highlighting them and pressing  /  on the projector or remote 
control
Adjusting Brightness
The higher the value, the brighter the image. And the 
lower the setting, the 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
The higher the value, the greater the contrast. Use this 
to set the peak white level after you have previously 
adjusted the Brightness setting to suit your selected 
input and viewing environment.
Adjusting Color
Lower setting produces less saturated colors. If the setting is too high, colors on the image 
will be overpowering, which makes the image unrealistic.
Adjusting Tint
The higher the value, the more reddish the picture becomes. The lower the value, the 
more greenish the picture becomes.

Adjusting Sharpness
The higher the value, the sharper the picture becomes. The lower the value, the softer the 
picture becomes.
Adjusting Brilliant Color
This feature utilizes a new color-processing algorithm and system level enhancements to 
enable higher brightness while providing truer, more vibrant colors in picture. It enables a 
greater than 50% brightness increase in mid-tone images, which are common in video and 
natural scenes, so the projector reproduces images in realistic and true colors. If you 
prefer images with that quality, select On. If you don’t need it, select Off.
On is the default and recommended selection for this projector. When Off is selected, the 
Color Temperature function is not available.
Selecting a Color Temperature
The options available for color temperature* settings vary according to the signal type 
selected.
1.T1: With the highest color temperature, T1 makes the image appear the most bluish 
white than other settings.
2.T2: Makes images appear bluish white.
3.T3: Maintains normal colorings for white.
4.T4: Makes images appear reddish white.
*About color temperatures:
There are many different shades that are considered to be white for various purposes. 
One of the common methods of representing white color is known as the “color 
temperature”. A white color with a low color temperature appears to be reddish white. A 
white color with a high color temperature appears to have more blue in it.
3D Color Management
In most installation situations, color management will not be necessary, such as in 
classroom, meeting room, or lounge room situations where lights remain on, or where 
building external windows allow daylight into the room. 
Only in permanent installations with controlled lighting levels such as boardrooms, lecture 
theaters, or home theaters, should color management be considered. Color management 
provides fine color control adjusent to allow for more accurate color reproduction, should 
you require it.
Proper color management can only be achieved under controlled and reproducible viewing 
conditions. You will need to use a colorimeter (color light meter), and provide a set of 
suitable source images to measure color reproduction. These tools are not provided with 
the projector, however, your projector supplier should be able to provide you with suitable 
guidance, or even an experienced professional installer.
The Color Management provides six sets (RGBCMY) of colors to be adjusted. When you 
select each color, you can independently adjust its range and saturation according to your 
preference.
If you have purchased a test disc which contains various color test patterns and can be 
used to test the color presentation on monitors, TVs, projectors, etc. You can project any 
image from the disc on the screen and enter the 3D Color Management menu to make 
adjusents.
To adjust the settings:
1. Go to the PICTURE menu and highlight 3D Color Management.

							Operation 402. Press MODE/ENTER and the 3D Color Management page displays.
3. Highlight Primary Color and press  /  to select a color from among Red, 
Yellow, Green, Cyan, Blue, or Magenta.
4. Press   to highlight Hue and press  /  to select its range. Increase in the range 
will include colors consisted of more proportions of its two adjacent colors.
Please refer to the illustration to the right 
for how the colors relate to each other.
For example, if you select Red and set its 
range at 0, only pure red in the projected 
picture will be selected. Increasing its range 
will include red close to yellow and red close 
to magenta.
5. Press   to highlight Saturation and adjust 
its values to your preference by pressing  /
. Every adjusent made will reflect to the 
image immediately.
For example, if you select Red and set its 
value at 0, only the saturation of pure red will be affected.
Saturation is the amount of that color in a video picture. Lower settings produce less 
saturated colors; a setting of “0” removes that color from the image entirely. If the 
saturation is too high, that color will be overpowering and unrealistic.
6. Press  to highlight Gain and adjust its values to your preference by pressing  /
. The contrast level of the primary color you select will be affected. Every adjusent 
made will reflect to the image immediately. 
7. Repeat steps 3 to 6 for other color adjusents.
8. Make sure you have made all of the desired adjusents.
9. Press MENU/EXIT to exit and save the settings.
