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.

NOTE
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
their factory values, as described
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
the set-top is disconnected from
the HDTV, then reconnect the
HDTV via an HDMI cable.
