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.
To change the projected picture ratio (no matter what aspect the source is):
Using the remote control
1. Press ASPECT to show the current setting.
2. Press ASPECT repeatedly to select an aspect ratio to suit the
format of the video signal and your display requirements.
Using the OSD menu
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.
1. 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.
2. 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 23 and "Obtaining a preferred projected
image size" on page 15 for details.
3. Auto: 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.
