Ergonomics, Ecology and Safety Standards

Q13: What is Image Sticking, or Image Burn-in, or After Image, or Ghost Image in LCD
panels?
A:
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 "atter-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.
WARNING: 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.
Q14: Why is my Display not showing sharp text, and is displaying jagged characters?
A:
Your LCD monitor works best at its native resolution of 1680x1050@60Hz. For
best display please use this resolution.
