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, 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):
• 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.
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.
16:9 aspect ratio is only sourced through the Component Video input when 
being fed an appropriate 16:9 aspect signal. See Connecting a Component 
Video source device on page 23 and Obtaining a preferred projected 
image size on page 15 for details.
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. 
						

							Operation 35 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.
OSD menus can be displayed on those unused black areas.
Optimizing the image
Using Wall Color
In the situation where you are projecting onto a colored surface such as a painted wall which

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 ENTER on the 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.
