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. 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
19. 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 14.
1. Press the
U
or
D
button until the front panel shows “reS” (short for resolution). On the 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*, or 1080p30* (the last three 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 USER SETTINGS menu reappears.
To continue making the settings, see the next section.
TV Display Capability
1080i
: YES
720p
: NO
480p
: YES
480i
: YES
1080p24 Pass : YES
1080p30 Pass : YES
If the highlighted resolution is currently
set, the MESSAGE light is lighted and
YES is on the menu
* NOTE
If your HDTV is 1080p-compliant and connected by HDMI, setting “1080p24 Pass” to YES causes 1080p/24
transmissions (at 24 frames per second) to be displayed at 1080p/24. Likewise, setting “1080p30 Pass” to
YES causes 1080p/30 transmissions (at 30 frames per second) to be displayed at 1080p/30.
The HDMI-connected HDTV may report that it is not 1080p-compliant and set “1080p24 Pass” (or “1080p30
Pass”) to NO. In this case 1080p transmissions will be output at one of the other resolutions (1080i, 720p,
480p, or 480i). If you override this NO setting and set YES, you may see nothing for 1080p transmissions.
If the HDTV is not connected by HDMI, “HDMI Cable Required” is displayed and you cannot set “1080p24
Pass” or “1080p30 Pass” to either YES or NO.
