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.

3.T3: Maintains normal colorings for white.
4.T4: 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.
