display requirements. 
						

							Operation 26
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.
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 some computer monitors, standard 
definition TV and 4:3 aspect DVD movies, 
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
There are two user-definable modes if the current available picture modes are not suitable 
for your need. You can use one of the picture modes (except the User 1/2) as a starting point 
and customize the settings.
1. Press MENU/EXIT to open the On-Screen Display (OSD) menu.
2. Go to the PICTURE > Picture Mode menu.

							Operation 288. 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.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 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 
p ro j e c to r,  h ow e ve r,  yo u r  p ro j e c to r  s u p p l i e r  s hould 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.
