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.
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:
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.
