MAKING USER SETTINGS (cont.)

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 always depends 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 “1080p”, “1080i”, or “720p”. Many

HDTVs will display at more than one resolution. For more information, see the information supplied with

your HDTV. See also the note, right.

You may need to make appropriate TV Display Capability settings 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 must select every resolution that your TV is capable of

displaying. This ensures that programs are displayed with minimum distortion.

There are ﬁve front-panel lights for the various resolutions. The appropriate one lights up to show the

resolution of the transmission your set-top is currently receiving (not the resolution of the signals at the

outputs of your set-top).

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,1080i, and 1080p are HDTV and are

transmitted in a 16:9 aspect ratio (see right).

480i transmission:

The aspect ratio is 4:3

1080i transmission:

The aspect ratio is 16:9

NOTE

When your HDTV and set-top are

connected by an HDMI

connector,

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

22. 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 the HDMI cable is disconnected

from your set-top, then reconnect your

HDTV via the HDMI cable.

Changing the TV Display Capability

If you have not already done so, put your set-top into User Settings mode, as described on page 15.

1. Press the U or D button on your remote control until the front panel shows “reS” (short for resolution).

On the PACE USER SETTINGS menu, TV Display Capability is highlighted when “reS” is on the front

panel.

2. Press the R button when you see “reS” on the front panel.

The front panel shows the TV display capability that was last selected, so it could show 480i, 480P, 720P,

1080i, 1080p24 Pass*, 1080p30 Pass* or 1080p60 (the last four settings are displayed as 1080). The TV

Display Capability menu, shown right, appears on your TV screen.

3. Press the U or D button to highlight each resolution in turn on the menu and, for each one, press the

OK/Select button if you wish to change the setting (the setting changes between “YES” and “NO” each

time you press OK/Select).

If, at any stage in this process, the menu disappears from the screen, immediately press

the OK/Select button to restore the menu.

4. When you are satisﬁed that all the TV resolutions are correct, press the L button. The front panel shows

“reS” again and the PACE USER SETTINGS menu reappears.

To continue making the settings, see the next section.

* See the note on the next page.
