Using the projector
Selecting the aspect ratio
The "aspect ratio" is the ratio of the image width to the image height. Digital TV is usually in 16:9 ratio,
which is the default for this projector, and most analog TV signals and DVDs are in 4:3 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. Images can
be stretched in a linear manner so the whole of the image is stretched equally, or non-linearly, which
distorts the image.
To change the projected picture ratio (no matter what aspect the source is):
• Using the remote control
Press one of the aspect ratio keys to suit the format of the video signal and your display requirements.
• Using the OSD menu
1. Press
MENU
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.
The function is not available when the 3D Mode is set to
2D 3D Conversion.
About the aspect ratio
1.
Anamorphic
(
ANA
): Scales an image so that it is displayed in the
center of the screen with a 16:9 aspect ratio. This setting stretches and
resizes linearly, except that it treats the vertical and horizontal
dimensions independently. It stretches the height of the source image
until it reaches the full projected height, and stretches the width of the
source image until it reaches the full projected width. This may alter
the projected aspect, depending upon the original aspect of the source
image. Anamorphic is most suitable for images which are already in a
16:9 aspect, like high definition TV, as it displays them without aspect
alteration.
2.
4:3
: Scales a picture so that it is displayed in the center of the screen
with a 4:3 aspect ratio. This is most suitable for 4:3 pictures like
computer monitors, standard definition TV and 4:3 aspect DVD
movies, as it displays them without aspect alteration.
3.
Letter Box
(
LB
): Scales a picture to fit the projector’s native
resolution in its horizontal width and resize the picture’s height to the
3/4 of the projection width. This may produce a picture greater in
height than can be displayed, so part of the picture is lost (not
displayed) along the top and bottom edges of the projection. This is
suitable for the display of movies which are presented in letter box
format (with black bars on the top and bottom).
4.
Wide
: Stretches the picture horizontally in a non-linear manner, that
is, the edges of the picture are stretched more than the center of the
picture to prevent distortion of the central part of the picture. This is
suitable for occasions where you want to stretch the width of a 4:3
aspect picture to the width of a 16:9 aspect screen. It does not alter the
height. Some widescreen movies have been produced with their width
squashed down to the width of a 4:3 aspect, and are best viewed when
restretched back to their original width using this setting.
