About TV Display Capability (resolution settings)

• The set-top can transmit pictures to the TV in a range of resolutions (also called "Display
Capabilities" - see below for the settings available). Generally, higher screen resolutions give better
quality pictures. However, the quality will always depend on how the program was originally
transmitted.
• Different TVs display different screen resolutions. For example, standard TVs display "480i", EDTVs
(Enhanced Definition TVs) display "480p" and most HDTVs display "1080i" or "720p". Many
HDTVs will display at more than one resolution. For more information, see the information
supplied with the HDTV.
You must make the appropriate TV Display Capability setting(s) on the set-top, so that it is
compatible with the TV. See the next page for full instructions.
In order to display the best picture every time, you should select every resolution that the TV is
capable of displaying. This should ensure that programs are displayed with the minimum distortion.
TV Display Capability settings
• 480i is standard definition NTSC and is transmitted
in a 4:3 aspect ratio (see right)
• 480p is enhanced digital TV and can be transmitted
in either a 4:3 or 16:9 aspect ratio
• 720p and 1080i are HDTV and are transmitted in
a 16:9 aspect ratio (see right)

When an HDTV is connected
to the set-top via an HDMI, the
set-top gets information from
the HDTV about the HDTV's
display capability. The set-top uses
this information to adjust its TV
Display Capability settings.
The set-top also records the
HDTV's ID (identification), so that
only one HDTV is supported at
any one time. When the HDTV has
updated the set-top's TV Display
Capability settings, you may change
them if you wish. Your changes will
then be stored with the ID.
You can restore the set-top's
TV Display Capability settings to
480i transmission:
their factory values, as described
The aspect ratio is 4:3
on page 52. You can also restore
the set-top to the settings that
the HDTV has passed to the
set-top. To do this you must first
restore the factory settings while
1080i transmission:
the set-top is disconnected from
The aspect ratio is 16:9
the HDTV, then reconnect the
HDTV via an HDMI cable.
