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):
• 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. 
						

							Operation 36
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 move the projector away from 
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 images aspect DVD movies, as it 
displays them without aspect 
alteration. 4.16:6: Scales an image so that it is 
displayed in the center of the screen 
with a 16:6 aspect ratio. (Available in 
MH856UST) 
5.16:9: 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. 
6.16:10: Scales an image 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.

Fine-tuning the image quality in user modes
According to the detected signal type, and selected picture mode, some of the functions 
listed below may not be available. Base on your need, you can make adjustments to these 
functions by highlighting them and press ◄/► on the projector or remote control.
Adjusting Brightness
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
The higher the value, the greater 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
Lower setting produces less saturated colors. If the setting is too high, colors on the image 
will be overpowering, which makes the image unrealistic.
Adjusting Tint
The higher the value, the more reddish the picture becomes. The lower the value, the 
more greenish the picture becomes.
Adjusting Sharpness
The higher the value, the sharper the picture becomes. The lower the value, the softer the 
picture becomes.
Adjusting Brilliant Color
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.
When Off is selected, the Color Temperature function is not available. 
						

							Operation39
Selecting a Color Temperature
The options available for color temperature* settings vary according to the signal type 
selected.
1.Cooler: makes the image appear bluish white.
2.Normal: Maintains normal colorings for white.
3.Wa r m : 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.
Setting a preferred color temperature
To set a preferred color temperature:
1. Highlight Color Temperature and select Wa r m, Normal or Cool by pressing 
◄/► on the projector or remote control.
2. Press ▼ to highlight Color Temperature Fine Tuning and press MODE/
ENTER. The Color Temperature Fine Tuning page appears.

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.
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, Green, 
Blue, Cyan, Magenta and Yellow.
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.
