What Is the Setup
Wizard?

Before Y ou Begin

Is It Necessary T o
Use the Setup
Wizard?

The Explorer HDTV Setup Wizard is an on-screen program that helps you set up
your high-definition TV (HDTV) to receive the best picture quality that the HDTV
supports. The Setup Wizard is currently available on select Explorer® Digital
Home Communications T erminal set-top models.

Before you begin to set up your HDTV , you may want to have available the users
guide that came with your HDTV for reference.

It depends on how the HDTV is connected to the set-top. If the Y , Pb, Pr ports on
the back of the set-top are connected to one of the video ports on the HDTV , you
should use the Setup Wizard to ensure that your HDTV receives the best picture
quality that it supports. Note: Make a note of which video input port the set-top is
connect to on the HDTV . For example: Video input port 6.

If the HDTV is connected to the composite port on the back of the set-top, it is not
necessary to use the Setup Wizard. Broadcasts coming in through the composite
port automatically adjust to the picture size and formats supported by the HDTV .

If the HDTV is connected to the DVI port on the back of the set-top, it may not be
necessary to use the Setup Wizard. TV programs coming in through the DVI
port of the HDTV are automatically adjusted if the broadcasted format is
supported by the HDTV. If the format is not supported, use the Setup Wizard.

Notes:

• The analog Y, Pb, Pr ports become inactive when the HDTV is
connected to the DVI port.

• If the HDTV is connected
to the DVI port on the
back of the set-top and
you see this DVI alert on
the screen, it means that
the HDTV and the set-top
are not compatible. If this
occurs, reconnect the
set-top to the Y, Pb, Pr
ports on the set-top.

What is the
Difference Between
a Standard Screen
and a Wide Screen?

What Is An Aspect
Ratio?

The type of screen your HDTV has (wide screen or standard screen)
determines how the set-top displays programs on the screen. The picture
format for an HDTV is a combination of aspect ratio and screen resolution
and is different for standard-screen and wide-screen HDTVs.

An aspect ratio is the ratio of the width to the height of the TV screen. The
aspect ratios differ because the television industry manufactures both
standard-screen and wide-screen HDTVs to appeal to consumer viewing
preferences.

A standard-screen HDTV has a
4:3 aspect ratio. The screen is 4
units wide for every 3 units tall.

A wide-screen HDTV is one-third
wider than a standard-screen
HDTV. The screen is 16 units
wide for every 9 units tall.

What is the Screen
Resolution?

The screen resolution indicates the amount of detail that the picture displays.
Resolution is identified by the number of display lines on the screen. The
techniques that an HDTV uses to “paint” the picture on the screen are referred
to as progressive and interlaced.

For example, a resolution of 1080i indicates that the screen shows 1080
lines in an interlaced display, and 480p means that the screen shows 480
lines in a progressive display.

Note: The screen resolution (1080i, 480p, etc.) is sometimes referred to as
the scan rate. The terms are interchangeable.

With the progressive
method, every pixel on
the screen is refreshed
simultaneously.

The interlaced method
involves refreshing pixels
in alternation—first the
odd lines and then the
even lines.
