Selecting the aspect ratio
The 'aspect ratio' is the ratio of the image width to the image height. For MP724 and MP727, the default aspect ratio is 4:3. And for MP735, the default aspect ration is 16:10. 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.

1.Auto:
MP724 and MP727: Scales an image proportionally to fit the projector's 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 image's aspect ratio.
MP735: Scales an image proportionally to fit the projector's native resolution in its horizontal width and vertical height. This is suitable for the incoming image which is in 4:3, 16:9 or 16:10 and you want to make most use of the screen without altering the image's aspect ratio.
