Image persistence occurs when a ghost of an image remains on
the screen after the monitor has been turned off. Unlike a CRT
monitor, an LCD monitor's image persistence is not permanent.
To erase an image ghost, turn the monitor off for as long as the
image was displayed. If the image was on for one hour and the
ghost of the image remains, the display should be turned off for
one hour to erase the image. To avoid this problem, use a screen
saver.
