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 source.
To change the projected picture ratio (no matter what aspect the source is):
•

4:3: Scales an image so that it is displayed in the
center of the screen with a 4:3 aspect ratio. This is
most suitable for 4:3 images like computer
monitors, standard definition TV and 4:3 aspect
DVD movies, as it displays them without aspect
alteration.

16:9: Scales an image so that it is displayed in the
center of the screen with a 16:9 aspect ratio. This is
most suitable for images which are already in a
16:9 aspect, like high definition TV, as it displays
them without aspect alteration.
