Image persistence Image persistence is when a “ghost” of an image
remains on the screen even after the monitor has been
turned off. Unlike CRT monitors, LCD monitors’
image persistence is not permanent. To alleviate
image persistence, turn the monitor off for as long as
an image was displayed. If an image was on the
monitor for one hour and a ”ghost” of that image
remains, the monitor should be turned off for one
hour to erase the image.
NOTE: As with all personal display devices, NEC
recommends using a screen saver at regular intervals
whenever the screen is idle.
