Adjusting the projected image
Adjusting the projection angle
The projector is equipped with an adjuster foot. It 
changes the image height  and vertical projection 
angle. Screw the adjuster foot to fine tune the 
angle until the image is positioned where you 
want it.
If the projector is not pl aced on a flat surface or 
the screen and the project or are not perpendicular 
to each other, the projected image becomes 
trapezoidal. To correct  this situation, see 
Correcting keystone on page 28  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.
Auto-adjusting the image
In some cases, you may need to optimize  the picture quality. To do this, press Auto Sync on 
the remote control. Within 5 seconds, the built -in Intelligent Auto Adjustment function will 
re-adjust the values of Frequency and Cl ock to provide the best picture quality.
The current source information will be displayed in  the upper left corner of the screen for 3 
seconds.
The screen will be blank while auto adjustment is functioning.
This function is only availabl e when PC D-Sub input signal  (analog RGB) is selected.

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 (n o matter what aspect the source is):
1. Open the OSD menu and go to the 
DISPLAY > Aspect Ratio  menu.
2. 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 reso lution 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. 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.
3. 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 wi thout aspect alteration.

4.Panorama : Scales a 4:3 image vertically and 
horizontally in a non-linear manner so that it 
fills the screen.
5. 2.35:1: Scales an image so that it is displayed in 
the center of the screen with a 2.35:1 aspect 
ratio without aspect alteration.
6. Anamorphic : Scales a 2.35:1 aspect image so 
that it fills the screen.
Optimizing the image
Selecting a picture mode

projector in well lit rooms.
2. Dynamic mode : Is designed for presentations under daylight environment to match 
PC and notebook coloring. In addition, the  projector will optimize the image quality 
using the dynamic PC function in accordance with the projected contents.
3. Standard mode : Is designed for presentations unde r daylight environment to match 
PC and notebook coloring.
4. ViewMatch sRGB mode : Switches between high br ightness performance and 
accurate color performance.
5. Movie mode : Is appropriate for playing colorf ul movies, video clips from digital 
cameras or DVs through the PC input for best  viewing in a blackened (little light) 
environment.

Using Screen Color
In the situation where you are projecting onto a colored surface such as a painted wall which 
may not be white, the Screen 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 > Screen Color menu and press  / to select a 
color which is closest to the color of the pr ojection surface. There are several precalibrated 
colors to choose from:  Whiteboard, Greenboard, and Blackboard. The effects of these 
settings may vary depending on different models.
This function is only available when a PC or HDMI input signal is selected.
Fine-tuning the image qu ality in user modes
According to the detected signal type, there  are some user-definable functions available. 
You can make adjustments to these functions based on your needs.
Adjusting Brightness
Go to the  PICTURE  > Brightness  menu and press  /.
The higher the value, the br ighter 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
Go to the PICTURE  > Contrast menu and press  /.
The higher the value, the great er 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
Go to the  PICTURE  > Advanced  > Color menu and press  /.
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 the input signal is S-Video, Vide o, YPbPr (digital) or 
YCbCr (digital).
Adjusting Tint
Go to the  PICTURE  > Advanced  > Tint menu and press  /.
The higher the value, the more reddish the pict ure becomes. The lower the value, the more 
greenish the picture becomes.
This function is only available when the input signal is S-Video, Vide o, YPbPr (digital) or 
YCbCr (digital).
Adjusting Sharpness
Go to the  PICTURE  > Advanced  > Sharpness  menu and press  /.
The higher the value, the sharper the picture b ecomes. The lower the value, the softer the 
picture becomes.

This function is only available when the input signal is S-Video, Video, YPbPr (digital) or 
YCbCr (digital).
Adjusting Brilliant Color
Go to the  PICTURE  > Advanced  > Brilliant Color  menu and press  /.
This feature utilizes a new color-processing algorithm and system level enhancements to 
enable higher brightness while providing truer,  more vibrant colors in the projected picture. 
It enables a greater than 50% brightness incr ease in mid-tone images, which are common in 
video and natural scenes, so the projector reprodu ces images in realistic and true colors. If 
you prefer images with that quality, select a le vel that suits your need. If you don’t need it, 
select  Off.
Reducing image noise
Go to the  PICTURE  > Advanced  > Noise Reduction  menu and press /.
This function reduces electrical  image noise caused by different media players. The higher 
the setting, the less the noise.
This function is only available when a PC, Video or S-Video input signal is selected.
Selecting a gamma setting
Go to the  PICTURE  > Advanced  > Gamma  menu and select a preferred setting by 
pressing  /.
Gamma refers to the relationship betw een input source and picture brightness.
Selecting a Color Temperature
Go to the PICTURE  > Color Temp.  menu and press  /.
The options available for color temperature  settings vary according to the signal type 
selected.
1. Cool: With the highest color temperature,  Cool makes the image appear the most 
bluish white than other settings.
2. Neutral:  Makes images appear bluish white.
3. Normal:  Maintains normal colorings for white.
4. Warm: Makes images appear reddish white.
Setting a preferred color temperature
1. Go to the  PICTURE > Color Temp.  menu.
2. Press  / to select  Cool, Neutral , Normal  or Warm  and press  Enter.
3. Press  / to highlight the item you want to change and adjust the values by
