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. “Burnin”,

“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
