							Operation 25 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 picture 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 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.4.16:9: 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.
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.5.16:10: Scales an image so that it 
is displayed in the center of the 
screen with a 16:10 aspect ratio. 
This is most suitable for images 
which are already in a 16:10 
aspect, as it displays them without 
aspect alteration.

Optimizing the image
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 
colors 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 closest to the color of the projection surface. There are several 
precalibrated colors to choose from: Light Yellow, Pink, Light Green, Blue, and 
Blackboard.
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.
To select an operation mode that suits your need, you can follow one of the following 
steps.
• Press MODE/ENTER on the projector or remote control repeatedly until your 
desired mode is selected.
•  Go to the PICTURE > Picture Mode menu and press  /  to select a desired 
mode.
1.Dynamic mode: Maximizes the brightness of the projected image. This mode is 
suitable for environments where extra-high brightness is required, such as using the 
projector in well lit rooms.
2.Presentation mode: Is designed for presentations. The brightness is emphasized in 
this mode to match PC and notebook coloring.
3.sRGB mode: Maximizes the purity of RGB colors to provide true-to-life images 
regardless of brightness setting. It is most suitable for viewing photos taken with an 
sRGB compatible and properly calibrated camera, and for viewing PC graphic and 
drawing applications such as AutoCAD.
4.Cinema 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 1/User 2 mode: Recalls the settings customized based on the current 
available picture modes. See Setting the User 1/User 2 mode on page 27 for details.
Setting the User 1/User 2 mode

							Operation 286. Press  to select a menu item to be changed and adjust the value with /. See 
Fine-tuning the image quality in user modes below for details.
7. When all settings have been done, highlight Save Settings and press MODE/
ENTER to store the settings.
8. The confirmation message “Setting Saved” displays.
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 is selected. Based on your needs, you can make adjustments to 
these 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.
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.Cool: Makes images appear bluish white.
2.Normal: Maintains normal colorings for white.
3.Warm: Makes images appear reddish white.

							Operation 29 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 adjustment 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 
adjustments.
To adjust the settings:
1. Go to the PICTURE menu and highlight 3D Color Management.
2. Press MODE/ENTER on the projector or remote control 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 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.
