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.
Note:
• Only standard format is available for Split Screen.
• PC formats vary depending on the PC signal.
• For 1080p signals from an HDMI input, see “Com-
puter Display Formats” in chapter 6, “Using the TV
with a Personal Computer.”
Signal Definitions
480i Signals: Traditional analog interlaced signals from
or through ANT-1 and 2, INPUT 1–3, COMPONENT
1 and 2, HDMI 1 and 2.
480p Signals: Progressive-scan DVD signals on COM-
PONENT inputs and HDMI 1 and 2 .
720p and 1080i Signals: High-definition signals received
through COMPONENT inputs and HDMI 1 and 2.
These signals are always 16:9 (widescreen).
SD 4:3: Standard-definition narrow-screen format signals
from digital channels and IEEE 1394 devices.
SD 16:9: Standard-definition widescreen format signals
from digital channels and IEEE 1394 devices.
HD: High-definition wide-screen format signals from digital
channels and IEEE-1394 devices. These signals are always
16:9 (widescreen).
DVD Definitions
Anamorphic (or Enhanced for WideScreen TV)
These DVDs are recorded in a special way to properly
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.
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, crop-
ping 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 displaying
menus or Split Screen, press to adjust the position of
the 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. As a result,
the broadcaster must convert such programming
for broadcast, and may stretch the image or add
side bars to fill the widescreen area.
