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 reso lution 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. 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.
3. 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 wi thout aspect alteration.

Using Screen Color
In the situation where you are projecting onto a  colored surface such as a painted wall which 
may not be white, the  Screen Color feature can help correct the  projected picture’s colors to 
prevent possible color difference between  the source and projected pictures.
To use this function, go to the  DISPLAY > Screen Color  menu and press  /  to select a 
color which is closest to the color of the pr ojection surface. There are several precalibrated 
colors to choose from:  Whiteboard, Greenboard , and Blackboard .
This function is only available when a PC type input signal is selected.
Fine-tuning the image qu ality 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 the  PICTURE > Brightness  menu and press  / .
The higher the value, the br ighter 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
Highlight the  PICTURE > Contrast  menu and press  / .
The higher the value, the great er the contrast. Use this 
to set the peak white level after you have previously

Operation 31
Adjusting Color
Highlight the PICTURE > Color  menu and press  / .
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
Highlight the  PICTURE > Tint  menu and press  / .
The higher the value, the more reddish the pict ure becomes. The lower the value, the more 
greenish the picture becomes.
Adjusting Sharpness
Highlight the  PICTURE > Sharpness  menu and press  / .
The higher the value, the sharper the picture b ecomes. The lower the value, the softer the 
picture becomes.
Adjusting Brilliant Color
Highlight the  PICTURE > Brilliant Color  menu and press  / .
This feature utilizes a new co lor-processing algorithm and system level enhancements to 
enable higher brightness while providing truer,  more vibrant colors in the projected picture. 
It enables a greater than 50% brightness incr ease in mid-tone images, which are common in 
video and natural scenes, so the projector reprodu ces images in realistic and true colors. If 
you prefer images with that quality, select  On. If you don’t need it, select  Off.
When  Off is selected, the  Color Temperature  function is not available.
Selecting a Color Temperature
Highlight the PICTURE > Color Temperature  menu and press  / .
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 cons idered to be white for various purposes. One 
of the common methods of representing white co lor is known as the “color temperature”. A 
white color with a low color temperature appear s to be reddish white. A white color with a 
high color temperature appears to have more blue in it.

Color Management
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 adjustment to allo w for more accurate color reproduction, should 
you require it.
If you have purchased a test disc which contains  various color test patterns and can be used 
to test the color presentation on monitors, TV s, projectors, etc., you can project any image 
from the disc on the screen and enter the  Color Management menu to make adjustments.
To adjust the settings:
1. Go to the  DISPLAY menu and highlight  Color Management .
2. Press  MODE/ENTER  on the projector or  Enter on the remote control  and the  Color 
Management  page is displayed.
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 adjustment 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 adjustment 
made will reflect to the image immediately. 
7. Repeat steps 3 to 6 for other color adjustments.
8. Make sure you have made all of the desired adjustments.
9. Press  MENU/EXIT  on the projector or  Exit on the remote control to exit and save the 
settings.

screen.
Operating in a high altitude environment
We recommend you use the  High Altitude Mode when your environment is between 1500 
m–3000 m above sea level, and temperature is between 0°C–35°C.
CAUTION
Do not use the High Altitude Mode if your altitude is between 0 m and 1500 m and temperature 
is between 0°C and 35°C. The projector will be  over cooled, if you turn the mode on under 
such a condition.
To activate the  High Altitude Mode :
1. Press  MENU/EXIT  on the projector or  MENU 
on the remote control and then press  /  until 
the  SYSTEM SETUP: Advanced  menu is 
highlighted.
2. Press  to highlight  High Altitude Mode and 
press /  to select  On. A confirmation 
message is displayed.
3. Highlight  Yes and press  MODE/ENTER  on the projector or  Enter on the remote 
control.
Operation under  High Altitude Mode  may cause a higher decibel operating noise level 
because of increased fan speed necessary  to improve overall system cooling and 
performance.
If you use this projector under other extreme  conditions excluding the above, it may display 
auto shut-down symptoms, which is designed to  protect your projector from over-heating. 
In cases like this, you should switch to  High Altitude Mode to solve these symptoms. 
However, this is not to state that this pr ojector can operate under any and all harsh or 
extreme conditions.
We recommend you use the High Altitude 
mode by selecting it whenever your 
environment is higher than 1500 m.
Do you want to turn High Altitude Mode 
ON?
