Imaging Problems
An "after-image", "burn-in" or "ghost image"
remains after the power has been turned off.
• Uninterrupted display of still or static
images over an extended period may cause
"burn in", also known as "after-imaging "
or "ghost imaging", on your screen. "Burn-
in", "after-imaging", or "ghost imaging" is a
well-known phenomenon in LCD panel
technology. In most cases, the "burned in"
or "after-imaging" or "ghost imaging" will
disappear gradually over a period of time
after the power has been switched off.
• Always activate a moving screen saver
program when you leave your monitor
unattended.
• Always activate a periodic screen refresh
application if your LCD monitor will display
unchanging static content.
• Failure to activate a screen saver, or a
periodic screen refresh application may
result in severe “burn-in” or “after-image” or
“ghost image” symptoms will not disappear
and cannot be repaired. The damage
mentioned above is not covered under
your warranty.
Image appears distorted. Text is fuzzy or
