							Operation 32
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 source.
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.
1.4:3: 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.
2.16:9: 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.
3.
Auto: Scales an image proportionally to fit the projectors 
native resolution in its horizontal width. This is suitable for the 
incoming image which is either in 4:3 nor 16:9 and you want 
to make most use of the screen without altering the images 
aspect ratio.
4.
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.

							Operation 35
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. 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

the projector or remote control.
Lower setting produces less saturated colors; setting to the minimum value makes 
the image black and white. If the setting is too high, colors on the image will be 
overpowering, which makes the image unrealistic.
Adjusting Tint
Highlight Tint in the PICTURE menu and adjust the values by pressing  / on 
the projector or remote control.
The higher the value, the more reddish the picture becomes. The lower the value, 
the more greenish the picture becomes.
Adjusting Sharpness
Highlight Sharpness in the PICTURE menu and adjust the values by pressing  / 
 on the projector or remote control.
The higher the value, the sharper the picture becomes. The lower the value, the 
softer the picture becomes.

Adjusting BrilliantColor™
Highlight BrilliantColor™ in the PICTURE menu and select by pressing  / on 
the projector or remote control.
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.
Selecting a color temperature
Highlight Color Temperature in the PICTURE menu and adjust the values by 
pressing  /  on the projector or remote control.
There are four color temperature* settings available.
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 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. 
						

							Operation 37 To adjust the settings:
1. Go to the PICTURE menu and highlight 3D Color Management.
2. 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 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 
/ . This will affect the contrast level of the primary color selected. Every 
adjustment made will be reflected to the image immediately. 
7. Repeat steps 3 to 6 for other color adjustments.
8. Make sure you have carried out all of the desired adjustments.
