The warranty will not cover any damage caused by using the product in an excessively dusty environment.
Afterimage
• After-image appears when the product is turned off.
- Pixels may be damaged rapidly if a still image is displayed on the screen for a long period of time. Use the
screen-saver function.
- Switching from a screen with high differences in luminance (black and white or grey) to a darker screen may
cause an afterimage. This is normal due to the display characteristics of this product.
• When the LCD screen is in a still pattern for extended periods of use, a slight voltage difference may occur
between the electrodes that operate the liquid crystal (LC). The voltage difference between the electrodes
increases over time and tends to keep the liquid crystal aligned in one direction. At this time, the previous image
remains, which is called an afterimage.
• Afterimages do not occur when continuously changing images are used but take place when a certain screen is
fixed for a long time. The following are operational recommendations for reducing the occurrence of afterimages
when using a fixed screen. The maximum recommended time for switching the screen is 12 hours. Shorter cycles
are better for preventing afterimages.
