About TV Display Capability (resolution settings)
•
Your set-top
can transmit pictures to your 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 your HDTV.
You must make the appropriate TV Display Capability setting(s) on your set-top, so that it is
compatible with your TV. See the next page for full instructions.
In order to display the best picture every time, you should select
every
resolution that your TV is
capable of displaying. This should ensure that programs are displayed with the minimum distortion.

MAKING USER SETTINGS (cont.)
NOTE
When your HDTV is connected
to your set-top via an HDMI, your
set-top gets information from
your HDTV about the HDTV’s
display capability. Your set-top uses
this information to adjust its TV
Display Capability settings.
Your set-top also records your
HDTV’s ID (identification), so that
only one HDTV is supported at any
one time. When your HDTV has
updated your 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 your set-top’s
TV Display Capability settings to
their factory values, as described
on page 31. You can also restore
your set-top to the settings that
your HDTV has passed to your
set-top. To do this you must first
restore the factory settings while
your set-top is disconnected from
your HDTV, then reconnect your
HDTV via an HDMI cable.
