Image persistence
• Imagepersistenceiswhena“ghost”ofanimageremainsonthescreenevenafterthemonitorhasbeenturnedoff.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 the monitor off for as long as an 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 screen saver at regular intervals
whenever the screen is idle or turning off the monitor when not in use.
