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.

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.

You can change the projected image ratio (no matter what aspect the source is) by entering

Pro-Picture > Aspect Ratio. Select an aspect ratio to suit the format of the

video signal and your display requirements. There are three aspect ratios available:

In the pictures below, the black portions are inactive areas and the white portions are active

areas.

1. Native: Scales an image proportionally to fit the projector's native

resolution in its horizontal width. This is suitable for the incoming

image which is either in 4:3 nor 16:9 and you want to make most use

of the screen without altering the image's aspect ratio.

2. 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.

3. 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.

16:9 aspect ratio is only sourced through the Component Video input when

being fed an appropriate 16:9 aspect signal. See "Connecting a Component Video source

device" on page 20 and "Obtaining a preferred projected image size" on page 14 for details.
