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 1920x1080@60Hz. For best display please use this resolution.
