images (movies).
• The input signal type effects the options available for the Picture Mode.  See  Selecting a picture mode on page 38  for details.
• The native display resolution of MX723 is in a 4:3 aspect ratio while the  native display resolution of MW724 is in a 16:10 aspect ratio. For best 
display picture results, you should se lect and use an input signal which 
outputs at this resolution. Any other  resolutions will be scaled by the 
projector depending upon the aspect ratio setting, which may cause 
some image distortion or loss of picture clarity. See  Selecting the 
aspect ratio on page 37  for details.
Changing Color Space

Operation 37
Selecting the aspect ratio
The aspect ratio is the ratio of the image width to the image height.
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 selected.
2. Press
  to select  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. 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 or 
vertical 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 adjusents.
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

38 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.
5. 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, like high definition TV, 
as it displays them with out aspect alteration.
Optimizing the image
Selecting a picture mode
The projector is preset with several predefined 
picture modes so that you can choose one to 
suit your operating environment and input 
signal picture type.
To select an operation mode that suits your 
need, you can follow one of the following steps.
• Press  Mode/Enter  on the remote control 
or projector repeatedly until your desired 
mode is selected.
•Go to the  PICTURE > Picture Mode  menu and press  /  to select a desired 
mode.

suitable for environments where extra-high brightness is required, such as using 
the projector in well lit rooms.
2. Presentation  mode (Default): Is designed for presentations. The brightness is 
emphasized in this mode.
3. sRGB  mode: Maximizes the purity of RGB colors to provide true-to-life images 
regardless of brightness setting. It is most suitable for viewing photos taken with 
an sRGB compatible and properly calibrated camera, and for viewing PC graphic 
and drawing applications such as AutoCAD.
4. Cinema  mode: Is appropriate for playing colorful movies, video clips from 
digital cameras or DVs through the PC input for best viewing in a blackened 
(little light) environment.
5. User 1/User 2  mode: Recalls the settings customized based on the current 
available picture modes. See  Setting the User 1/User 2 mode on page 38  for 
details.

the Picture Mode sub-menu item.
5. Press  /  to select a picture mode that is closest to your need.
6. Press   to select a sub-menu item to be changed and adjust the value with  /
. See  Fine-tuning the image quality in user modes  below for details.
7. The settings will be saved when selecting.
Using Wall Color
In the situation where you are projecting onto a colored surface such as a painted wall 
which may not be white, the  Wall Color feature can help correct the projected 
picture’s color to prevent possible color difference between the source and projected 
pictures.
To use this function, go to the  DISPLAY > Wall Color  menu and press  /  to 
select a color which is the closest to the color of the projection surface. There are 
several precalibrated colors to choose from: Light Yellow, Pink, Light Green, Blue, and 
Blackboard.
Fine-tuning the image quality in user modes
According to the detected signal type, there are some user-definable functions 
available when  User 1 or User 2  mode is selected. Based on your needs, you can 
make adjustments to these functions by selecting them and pressing  /   on the 
projector or remote control.
Adjusting Brightness
The higher the value, the brighter 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
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.
You can also adjust  Brightness or Contrast  by using  
BRIGHT  or CONTRAST  key on the remote control.
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.
On  is the default and recommended selection for this projector. When  Off is 
selected, the  Color Temperature  function is not available.
Selecting a Color Temperature
The options available for color temperature* settings vary according to the signal type 
selected.
1.Cool:  Makes images 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 re presenting 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. Select  Color Temperature  and select Wa r m, Normal  or Cool  by pressing 
/   on the projector or remote control.
2. Press   to select  Color Temperature Fine Tuning  and press MODE/
ENTER . The Color Temperature Fine Tuning page displays.
3. Press  /  to select the item you want to change and adjust the values by 
pressing /  .
•R Gain/G Gain/B Gain : Adjusts the contrast levels of Red, Green, and Blue.
• R Offset/G Offset/B Offset : Adjusts the brightness levels of Red, Green, and 
Blue.
4. Press  MENU/EXIT  to exit and save the settings.
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.
