Chapter 5 Connecting Equipment
Which Video Connection Should I Use?
You have six options for connecting your video equipment box to your HDTV from a basic connection to
the most advanced for digital displays. Based on your Home Theater configuration, you can decide which
option is the right one for you.

HDMI
delivers the best image quality of any of the cable types available
and it’s all done over one cable. You get a great picture and cut down on
your cable clutter. HDMI provides digital quality and amazing sound so if
your TV has HDMI, this is the connection type you should be using.

Connect your
antenna
or
coaxial
cable to watch TV programming. This
cable usually comes from your Cable box or right out of the wall.

The
RGB (VGA)
port allows you to connect your computer so you can
use the TV as your monitor.

(analog)
Component
consists of three cables for transmitting video and two
cables for transmitting audio: one red and one white. Component video
provides a sharper image than Composite video and should be used
instead of Composite when possible. However, because it is still an
analog connection, it won’t provide the highest quality video and audio
that HDMI can produce.
Good
(analog)
Composite
consists of one yellow cable for transmitting video and two
cables for transmitting audio: one red and one white. It is capable of
transmitting stereo sound and standard definition video (480i). While it
provides a good image, it has lower image quality than HDMI or
Component. So try to use one of those connections first.
Note:
You can use your HDTV Component input to accept A/V signal (Composite) from a source
with A/V out, please plug your video signal (yellow connector) into the Component input (green
connector) and match up the audio connectors (R and L) for the sound. Expect to see a
black/white video in the Component input, if it is selected by accident.
Note:
To maintain the display quality, use a VIZIO certified HDMI cable. This cable is available in 6, 8,
and 12 foot lengths. Visit www.vizio.com or call 1-888-VIZIOCE (1-888-849-4623) for details.
