Image persistence
• Imagepersistenceiswhenaresidualor“ghost”imageofapreviousimageremainsvisibleonthescreen.UnlikeCRT
monitors, LCD monitors’ image persistence is not permanent, but constant images being displayed for a long period of time
should be avoided. To alleviate image persistence, turn off the monitor for as long as the previous image was displayed.
For example, if an image was on the monitor for one hour and a residual image remains, the monitor should be turned off
for one hour to erase the image.
NOTE: As with all personal display devices, NEC DISPLAY SOLUTIONS recommends using a moving screen saver at regular
intervals whenever the screen is idle or turning off the monitor when not in use.
