Q13: What is Image Sticking, or Image
Burn-in, or After Image, or Ghost Image in
LCD panels?
Ans.: 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?
Ans.: Your LCD monitor works best at its native
resolution of 1680x1050@60Hz. For best
display please use this resolution.
