For example,
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
and
"Obtaining a preferred projected image size" on page 14
for details.
