Selecting the aspect ratio
The 'aspect ratio' is the ratio of the image width to the image height. For SP840, the default 
aspect ration is 16:9. 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.
