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 pattern frequently can leave a subtle but permanent
ghost image. 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.
This plasma display is a phosphor-based display. As is the
case with any phosphor-based display (like a CRT TV/
monitor, for example) light output will gradually decrease
over the life of a plasma display panel. Normal TV pictures
fill the screen with constantly changing images. Under these
conditions, phosphor-based displays age at an even rate across
the entire screen. This maintains a TV picture that is evenly
bright over the whole screen. Stationary images or images
that only partially fill the screen (leaving black or colored
bars to fill the screen), when used over extended periods of
time or when viewed repeatedly, can cause uneven aging of
the phosphors used in plasma displays and can leave subtle
ghosts of the stationary images in the picture.
When using a computer or similar device through a VGA
input, be sure to turn on the Screen Saver feature and set the
activation time to 5 minutes or less. If your computer program
allows, you should also set your toolbars to the hidden mode.
Still or stationary images may be received from broadcasters,
cable channels, satellite channels, DVD discs, video tapes,
laser discs, on-line services, web/internet searching devices,
video games, and digital TV tuner/converter boxes. Examples
of these types of images include, but are not limited to the
following:
• Letterbox top/bottom black bars: shown at the top and
bottom of the TV screen when you watch a widescreen
(16:9) movie on a standard (4:3) TV.
• Side bar images: solid bars shown on each side of an image
when watching a standard (4:3) program on a widescreen
(16:9) TV.
• Stock-market report bars: ticker running at the bottom
of the TV screen.
• Shopping channel logos & pricing displays: 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: or any other stationary or
repetitive computer style images.
• Closed Caption Backgrounds: If Close Caption will be
used frequently Mitsubishi suggests the use of the gray
background.
WARNING: Do not leave stationary or letterbox images on-screen
for extended periods of time. Mix types of pictures shown. Uneven
phosphor aging is NOT covered by your warranty.
