Image Persistence

Image persistence refers to when a residual or "ghost" image of a previous

image remains visible on screen. Unlike CRT monitors, with LCD monitors
image persistence is not permanent. However, displaying constant images for
long periods of time should be avoided.
To alleviate image persistence, power off the monitor for the same length of

time as the image was displayed. For example, if an image was displayed on
the monitor for one hour and a residual image remains, the monitor should be
powered off for one hour to erase the image.
Note! As with all personal display devices, Advantech recommends using a
moving screen saver whenever the screen is idle and turning off the
monitor when not in use.

Incorrect Display Image Size
