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 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

equipment or Japanese NTSC standards are used, the grayscale is measured from 0 IRE (black) to 100 IRE 
(white). We suggest that you check the input source to see if it is with 0 IRE or 7.5 IRE, then select 
accordingly.
Setting Noise Reduction
You may have static or noisy projected pictures. Noise Reduction reduces electrical image noise caused 
by different media players. The higher the setting, the less the noise. 
To achieve better picture clarity:
Highlight Noise Reduction and adjust the level by pressing  /  on the projector or remote control.
Selecting a color temperature*
Highlight Color Temperature and select a preferred setting by pressing  /  on the projector or 
remote control.
There are several color temperature settings available.
1.Lamp Native: With the lamp’s original color temperature and higher brightness. This setting is 
suitable for environments where high brightness is required, such as projecting pictures in well lit 
rooms.
2.Wa rm : Makes pictures appear reddish white.
3.Normal: Maintains normal colorings for white.
4.Cool: Makes pictures appear bluish 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.

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 3D Color Management provides six sets (RGBCMY) of colors to be adjusted to favorite colors. 
When you select each color, you can independently adjust its color range and saturation according to 
your preference.
To adjust and store the settings:
1. In the Picture menu, highlight Advanced... and press MODE/
ENTER. Then, highlight 3D Color Management and press 
MODE/ENTER. The 3D Color Management page is displayed.
2. Highlight Primary Color and press  /  to select a color from 
among Red, Green, Blue, Cyan, Magenta, and Yellow.
3. Press   to highlight Hue and press  /  to select the color range 
you wish to make adjustment. The bigger the range, the more 
proportions of its two adjacent colors the color contains.
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 is selected. Increasing its range will include both the red color close to yellow and red 
color close to magenta.
Press   to highlight Saturation and adjust the color saturation level by pressing  / . 
If you select Red and set its range at 0, only the saturation of the 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.
4. To leave and save the settings, press MENU/EXIT.

EnglishSelecting the aspect ratio
The aspect ratio is the ratio of the image width to the image height. The default for this projector is 
16:10 while digital TV and Blu-ray discs are usually in 16:9 ratio, and most analog TV signals and DVDs are 
in 4:3 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. Images can 
be stretched in a linear manner so the whole of the image is stretched equally, or non-linearly, which 
distorts the image.
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. 
						

							38 Using the projector  
EnglishAbout the aspect ratio
1.Auto: Scales a picture proportionally to fit the 
projectors native resolution in its horizontal or vertical 
width. This makes the most use of the screen and 
maintains the aspect ratio of a picture
 when projecting 
images that are neither 4:3 nor 16:10 ratio. 
2.4:3: Scales a picture so that it is displayed in the 
center of the screen with a 4:3 aspect ratio. This is 
most suitable for 4:3 pictures like computer monitors, 
standard definition TV and 4:3 aspect DVD movies, as 
it displays them without aspect alteration.
3.16:9: 
Scales a picture so that it is displayed in the center 
of the screen with a 16:9 aspect ratio.
 This is most 
suitable for 16:9 pictures like LCD monitors, high 
definition TV and 16:9 aspect DVD movies, as it 
displays them without aspect alteration.
4.16:10: 
Scales a picture 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.
5.Real: This setting displays the image in a one-to-one 
pixel mapping without alteration or resize in the 
center of the projection. This is most suitable for use 
with PC source inputs.
•  The black portions are inactive areas and the white 
portions are active areas.
•  OSD menus can be displayed on those unused black 
areas.
