Important User Guidance Information 01

About the menu window size following video format switch

The video program that you watch may be high definition (HD) or standard definition (SD). This Plasma Display is designed to scale to either HD or SD signals. If the video program’s definition type changes while a menu window is displayed on the screen (for example: HD → SD or SD → HD), the menu size may temporarily shrink or enlarge until the scaling is complete. For example, switching between a TV program and an external digital video recorder (D-VHS) while viewing a menu can cause the menu window size to fluctuate.

If this happens, the menu will return to its normal size after two to three seconds. This action is normal, and does not indicate a problem with your Plasma Display Panel.

Image Retention

When a static image is shown on a display for several hours, a faint imprint of the image, known as image retention, can remain. This image retention may be temporary or permanent. Although caused by different things, image retention can occur on all display technologies, including plasma and LCD. On today’s plasma displays, permanent image retention is less of a worry. Most image retention can be improved simply by watching a motion video sequence.

Image retention, also known as burn-in, can occur in all phosphor-based display systems (including CRT television systems–both direct view and projection–as well as plasma display systems). To avoid image retention or burn-in, do not show a still image for an extended period. Recommended guidelines are as follows:

•Do not display static images such as still images, fixed images from PC or TV game equipment, and/or fixed images such as time of day indicator or channel logo display for long periods.

•Do not display content in the 4:3 aspect ratio (black or gray bars on left and right side of content) or letter-box content (black bars above and below content) for extended periods of time, or use either of these viewing modes repeatedly within a short period of time. This plasma display system is equipped with multiple wide-screen viewing modes; use one of these screen modes to fill the entire screen with content.

•Displaying dark images after showing a still image for an extended time may cause image retention. In most cases, the image retention can be corrected by displaying bright images for a similar period of time.

Warning: Displaying a still image on the panel for a long period of time can cause the image to be burned in to the screen permanently.

CAUTION

Panel sticking and after-image lag

•Displaying the same images such as still images for a long time may cause after-image lagging. This may occur in the following two cases.

1After-image lagging due to remaining electric load

When image patterns with very high peak luminance are displayed for more than one(1) minute, after-image lagging may occur due to the remaining electrical load. The after- images remaining on the screen disappears when moving images are shown. The time for the after-images to disappear depends on the luminance of the still image and the length of time displayed.

2After-image (lag image) due to burning

Avoid displaying the same image on the Plasma Display continuously over a long period of time. If the same image is displayed continuously for several hours, or for shorter periods but over several days, a permanent after-image may remain on the screen due to burning of the fluorescent materials. Such images may become less noticeable if moving images are later displayed but they do not disappear completely.

NOTE

•When a program menu, TV Guide screen or frozen image is displayed for 5 to 10 minutes, the system automatically turns the screen off to prevent damage from screen burning.

•To prevent screen burning, the display position is automatically changed slightly when the power is switched on or the input changed. Depending on the broadcast content, some parts of the picture may not be visible.

Preventing damage from screen burning

•Please show images in full screen unless doing so causes copyright infringement. See page 65.

•The Energy save function can be set to help prevent screen burn-in. See page 63.
