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.
