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. Open the OSD menu and go to the 
DISPLAY > Aspect Ratio menu.
2. 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. 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.
2.4:3: 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.
3.16:9: 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.

the center of the screen with a 2.35:1 aspect 
ratio without aspect alteration.
6.Anamorphic: Scales a 2.35:1 aspect image so 
that it fills the screen.
