Change your TV’s input selection to match
its video source
If you’re unable to see TV programs on your screen, first try pressing the T V/VIDEO
button on your remote control to change from Video 1 to Video 2 or Video 3. These
separate video inputs (Video 1, Video 2, and Video 3) must match the incoming video
source—the receiver, DVD player, or other device connected to the TV. If this doesn’t
solve the problem, depending on how your devices are connected, it may be that the
TV’s input selection does not correspond to the input of the AT&T U-verse® TV receiver.
See two examples of how to connect the AT&T U-verse HD-ready receiver to
your HDTV set below.
Check device connections for your TV
TV screen menus and port configurations
vary. Most devices have ports that require
one or more of the cables shown at right.
The manuals for your devices will have
specific directions.
To connect your AT&T U-verse HD-ready
receiver to your HDTV set, the connection
is generally HDMI to HDMI (the highest
quality video/audio connection). You can
also use color-coded component RCA
cables (some HDTV sets do not have an
HDMI port) that deliver audio/video signals from the receiver and plug into matching
audio/video RCA inputs on the back of your HDTV set.
If you’ve connected your TV input using Composite (yellow connector), S-Video, or
Coaxial, you won’t get an HD picture. HD is supported only via HDMI or Component
(red/green/blue). The same holds true for Dolby® Digital 5.1 surround sound, which is
available only via HDMI or TOS Link (optical). The Baseband (red and white connectors)
delivers sound only in stereo.
Check to see if the TV recognizes your video inputs correctly
Many newer TVs have an auto-detection system that will automatically detect
equipment connected to the various ports on the TV. However, some TVs have to be
configured manually.
To change the video input selection manually, press TV/VIDEO on your remote control to
locate the video input menu for your specific TV.
The video input menu screen below shows checkboxes next to devices the TV is detecting.
This menu must match the inputs on the back of the TV where video components are
connected in order to correspond with Video 1, Video 2, or Video 3 on your remote
control. Follow the screen prompts to check/uncheck boxes for your devices.

Choose one of three easy ways to connect
your AT&T U-verse receiver to your TV
1
HDMI
Some HDTVs have a High-Definition Multimedia
Interface (HDMI) connector that provides the
digital and audio connection. This is the easiest
connection if your TV has an HDMI input port.
NOTE: If your HDTV has an input port marked DVI
(Digital Visual Interface), you will need an HDMI-to-
DVI adapter and separate component RCA audio
connectors.
2
Color-coded component connectors
If your TV doesn’t have an HDMI or DVI input port, you can use color-coded
component video cables (Pr, Pb, and Y) for HD video signals. For audio, plug red
and white RCA connectors into the left/right audio input and output ports.
