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, which is the default for this projector, and digital TV and DVDs
are usually in 16:9 ratio.

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 to open the pop-up menu in one
of the computer, iPhone/iPod, composite
video, component and HDMI modes.
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.
