broadcasts or enjoying other HD input sources. However,
when you resume the HD programs after having quit them,
“FULL” is automatically selected for the screen size.

5080HD. For the PDP-4280HD, the number of panel pixels is
different, and thus signal processing and actual viewing
conditions will vary slightly.

permanent image retention depending on the frequency and

Selecting a screen size automatically
The plasma display automatically selects an appropriate screen
size when video signals are received from a connected HDMI
device (see page 65). To activate this function, use the following
procedure.
1 Press HOME MENU.
2 Select “Option“ ( / then ENTER).
3 Select “Auto Size“ ( / then ENTER).
4 Select “Natural” or “Wide-Zoom” ( / then ENTER).
5 Press HOME MENU to exit the menu.
Note
• Manually select an appropriate screen size if an image does
not automatically switch to a correct screen format.
• When the video signal contains no aspect ratio information,
the function will not work even with “Natural” or “Wide-Zoom”
selected.
Detecting side masks
Some HD broadcasts may display 4:3 content with side masks.
The plasma display automatically detects these side masks to
provide gray side masks when “Natural” has been selected for
“Auto Size”, or display the image full screen with the side masks
removed when “Wide-Zoom” has been selected. This function
does not operate when “Off” is selected for “Auto Size”.

2 Select “Option“ ( / then ENTER).
3 Select “Side Mask“ ( / then ENTER).
4 Select “Detection” ( / ).

Important
• The “On” setting prevents uneven wear on 4:3 content and side
masks and can reduce the possibility of image retention.
Note
• You cannot set the Side Mask detection to “On” or “Off” when
“Off” is selected in “Auto Size”.
• Set the Side Mask detection function to “On”. The High
Definition 16:9 aspect ratio images containing side masks will
be detected automatically and side masks will be added or the
image displayed in full screen.
• This Side Mask detection does not operate on 4:3 content
displayed in SD (standard definition) broadcasts.
• “AUTO” will appear on the channel display when this function
is on.
• Detection errors may occur depending on the HD content. In
case a detection error occurs, manually change the screen size
to the desired size.
• Side Mask detection may not operate properly for video signals
that contain no aspect ratio information. If that is the case,
check if “FULL” is selected for the screen size, switch to
another input source, then switch back to the original input
source again.
