    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/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.
    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 or its vertical height. This is suitable 
    when you want to make most use of the screen without altering the 
    images aspect ratio.
    2.16:9: 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 and 16:9 aspect DVD 
    movies, as it displays them without aspect alteration.
    3.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.
    4.4:3: 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.

    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 is displayed.
    3. Highlight Primary Color and press  /  to select a color from among Red, Green, Blue, Cyan, Magenta, or

    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.
    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.

    Using Wall Screen
    In the situation where you are projecting onto a colored surface such as a painted wall which may not be white, the 
    Wall Screen 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 Screen menu and press  /  to select a color which is the closest 
    to the color of the projection surface. There are several recalibrated colors to choose from: Light Yellow, Pink, Light 
    Green, Blue, and Blackboard.
