TV Signals and Display Formats

This is a widescreen TV, also known as a 16:9 TV. This
shape reflects the new types of images available from
HDTV and many DVDs. There are still many older style
narrow-screen images (called 4:3 aspect ratio) you will
encounter. While there is no perfect solution for dis-
playing a squarish, narrower image on a wide screen,
Mitsubishi offers several display formats from which
you can choose.
Press FORMAT on the TV remote control to cycle through
the available display formats. The last-used format for
each device is used when you return to that device.
DVD Definitions
Anamorphic (or Enhanced for WideScreen TV)
These DVDs are recorded in a special way to prop-
erly show widescreen images on 16:9 TV sets using
the Standard format mode. This is the recommended
viewing choice.
Non-Anamorphic (or 4:3, 1:33:1, Letter Box, or Full
Screen)
These DVDs are recorded for use with traditionally
shaped, squarish TVs. They may be full screen (4:3 or
1:33:1) which crops movies to fit the narrow TV, or letter
box, which adds black top and bottom bars.
This information may be listed on the DVD case. Some
DVDs support both types of recordings.
Signal Definitions
480i Signals: Traditional analog interlaced signals
from or through ANT-1 and 2, INPUT 1–3, COMPONENT
and HDMI jacks.
480p Signals: Progressive-scan DVD signals on COM-
PONENT and HDMI jacks.
720p and 1080i Signals: High-definition signals
received through COMPONENT and HDMI jacks. These
signals are always 16:9 (widescreen).
SD 4:3:
Standard-definition squarish-screen format
signals from digital channels on ANT 1 and ANT 2.
SD 16:9:
Standard-definition widescreen format signals
from digital channels on ANT 1 and ANT 2.
HD:
High-definition wide-screen format signals from
digital channels on ANT 1 and ANT 2. These signals are
always 16:9 (widescreen).
TV Display Format Definitions
Standard: This is the full-screen format. HDTV signals
use this format. This format is useful for displaying
Anamorphic DVDs that have 1.78:1 or 1.85:1 aspect
ratios. Anamorphic DVDs that have a 2.35:1 aspect
ratio are displayed with black bars at the top and
bottom, but show the entire image correctly. Narrow
(4:3) images are stretched evenly from side to side.
Available for all signals.
Expand: This enlarges the picture to fill the screen,
cropping off some of the image at the top and bottom.
This is useful for reducing the letter box top and bottom
bars of non-anamorphic DVD images. Available for
480i, 480p, and digital SD 4:3 signals only.
Zoom: This enlarges the picture, cropping off some
of the image at each side and top and bottom. This
is useful for removing or reducing the black top and
bottom bars on anamorphic DVDs with a 2.35:1 aspect
ratio. Available for 480i, 480p, and SD 4:3 signals only.
Stretch: This format stretches a narrow (4:3) image
across the screen; there is less stretch in the center
than at the sides, however. This allows the entire
narrow image to be displayed across the screen with
less distortion than is seen in the Standard format.
Available for 480i, 480p, and SD 4:3 signals only.
Stretch Plus: Similar to stretch mode, but to minimize
distortions on the side, the picture is expanded to crop
off portions of the top and bottom. Except when dis-
playing menus, press
picture vertically. Available for 480i, 480p, and SD 4:3
signals only.
Narrow: This format displays narrow (4:3) images in
their original shape, and adds stationary black side
bars to fill the screen. Available for 480i, 480p, and SD
4:3 signals only.
Wide Expand: Enlarges the picture, cropping some of
the image on both sides. This Expand format is useful
to remove or reduce black side bars added to narrow
images that are converted to 16:9 signals for digital
broadcast. Available for 1080i, 720p, digital SD 16:9
and digital HD signals.
Note: All high-definition channels send widescreen
(16:9) signals, but not all programming sent on
these channels was created for this format. The
broadcaster may stretch the image or add side
bars to fill the widescreen area.
