Adjusting the projected image
Adjusting the projection angle
The projector is equipped with two adjuster feet. 
They change the image height and vertical 
projection angle. Screw the adjuster feet to fine 
tune the angle until the image is positioned where 
you want it.
If the projector is not placed on a flat surface or 
the screen and the projector are not perpendicular 
to each other, the projected image becomes 
trapezoidal. To correct this situation, see 
Correcting keystone on page 23 for details.
• Do not look into the lens while the lamp is on. The strong light from the lamp may cause 
damage to your eyes.
• Be careful when you screw the front adjuster foot as it is close to the exhaust vent where 
hot air comes from.

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 signal.
To change the projected image ratio (no matter what aspect the source is):
1. Press MENU on the projector or MENU/EXIT on the remote control 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. 
						

							25
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 
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.
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.
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 computer 
monitors, standard definition TV and 4:3 aspect 
DVD movies, as it displays them without aspect 
alteration.
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.

Lower setting produces less saturated colors. If the setting is too high, colors on the image 
will be overpowering, which makes the image unrealistic.
This function is only available when a Video, S-Video or Component Video signal is selected.
Adjusting Tint
Highlight the PICTURE > Tint menu and press  / .
The higher the value, the more reddish the picture becomes. The lower the value, the more 
greenish the picture becomes.
This function is only available when a Video, S-Video with NTSC signal is selected.
Adjusting Sharpness

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.
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 allow 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, 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 DISPLAY menu and highlight 3D Color Management.
2. Press MODE/ENTER on the projector or remote control and the 3D 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 on the projector or MENU/EXIT on the remote control to exit and save 
the settings.
