Important Information
Special Information Concerning Stationary Images or Letterbox Images:
For best performance and longest life, the normal use of a TV should include a mixture of TV picture types. The most
frequently used picture types should fill the screen with constantly moving images rather than stationary images or
patterns. Displaying the same stationary patterns over extended periods of time, or displaying the same stationary
patterns frequently, can cause uneven aging of the TV picture tubes and leave a subtle, but permanent, ghost image.
Most TV warranties do not cover this type of damage to the picture tubes. To avoid this, mix your viewing pattern. Do
not show the same stationary image for more than 15% of your total TV viewing in any one week. Display constantly
moving and changing images that fill the screen whenever possible. We also recommend that you reduce the contrast
setting of your TV when you watch that type of image. When possible, you may wish to use your television’s PIP, POP,
ZOOM, EXPAND or other picture shape controls so that the moving images fill the screen.
Please check your TV’s owner’s guide for other recommendations.
Examples of stationary images include:
• Letterbox top/bottom bars. These are solid colored bars that when showing a widescreen (16:9) image on a
standard (4:3) TV.
• Side panels. These are the solid colored side bars when showing standard shaped (4:3) TV images on a widescreen
(16:9) TV.
• Stock-market report bars. These include the ticker bar constantly running at the bottom of the TV screen on
financial news channels.
• Shopping channel logos & pricing displays. These include bright graphics that are shown constantly or
repeatedly in the same location.
• Video game patterns and scoreboards.
• Bright station logos. Moving or low-contrast graphics are less likely to cause uneven aging of the picture tubes.
• On-line (internet) web sites. In addition, any other stationary of repetitive computer style images from any source
may cause uneven aging of the picture tubes.
