Appendix G: TV Display and DVD Formats

TV Display Formats
The media center is designed to work with widescreen
TVs (also known as 16:9 TVs). 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 will never be a perfect solution for displaying
a narrow image on a wide screen, Mitsubishi offers
several display formats to choose from.
To cycle through the available display formats, press
FORMAT on the HDTV remote control . The last used
format for each device will be used when you return to
that device.
Note: Not all formats are available for
PIP/POP. Side-by-Side, 3 POP and 9 POP are only
available in Standard and Expand formats. PC
formats vary depending on PC signal.
TV Signal Definitions
480i Signals: Traditional analog interlaced signals from
or through Ant-1 & 2, Inputs 1 & 2, Component 1 & 2,
Input-DTV and HDMI.
480p Signals:
Progressive scan analog DVD signals on
Ant-1 & 2, Component-1 & 2, Input-DTV and HDMI.
720p & 1080i Signals:
received through Component-1 & 2, Input-DTV and HDMI.
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 wide screen 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).
TV Format Definitions
Standard: This is the full screen format. HDTV
signals use this format. This format is useful to display
Anamorphic DVDs that have 1.78:1 or 1.85:1 aspect
ratios. Anamorphic DVDs that have a 2.35:1 aspect ratio
will still display black bars at the top and bottom, but will
show the entire image correctly. Narrow (4:3) images
will be stretched evenly from side to side. Available for
all signals.
Expand: This will enlarge the picture to fill the screen,
cropping off some of the image at the top and bottom.
This is useful to reduce the letterbox top and bottom
bars of non-anamorphic DVD. Available for analog 480i,
480p and digital SD 4:3 signals only.

High definition analog signals
Zoom: This will enlarge the picture, cropping off some
of the image at each side and top and bottom. This is
useful to remove or reduce the black top and bottom
bars on anamorphic DVDs with a 2.35:1 aspect ratio.
Available for analog 480i and 480p and SD 4:3 signals
only.
Stretch: This format will stretch a narrow (4:3) image
across the screen, however, there is less stretch in the
center than the sides. This will allow the entire narrow
image to be displayed across the screen with less
distortion than seen in the Standard format. Available for
analog 480i and 480p and SD 4:3 signals only.
Stretch Plus: Similar to stretch mode, however to
minimize distortions on the side, the picture is expanded
to crop off portions of the top and bottom. Useful when
no important information is shown at the top and/or
bottom of the screen. Available for analog 480i and
480p and SD 4:3 signals only.
Narrow: This format will display narrow (4:3) images in
their original shape, and add stationary black or gray
side bars to fill the screen. Available for 480i, 480p and
digital 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 analog 1080i, 720p, digital SD
16:9 and digital HD signals.
DVD Formats
Anamorphic (or Enhanced for Widescreen TV's):
These DVDs are recorded in a special way to properly
show widescreen images on 16:9 TV sets in the Standard
format mode. This is the recommended choice.
Non-Anamorphic (or 4:3, 1:33:1, Letterbox or Full
Screen):
These DVDs are recorded for use with traditional shaped
TVs. They may be full screen (4:3 or 1:33:1) which crops
movies to fit the narrow TV, or Letterboxed which adds
black top and bottom bars.
This information may or may not be listed on the DVD
case. Some DVDs support both types of recordings.
