• Image persistence is when a residual or “ghost” image of a previous image remains visible 

on the screen. Unlike CRT 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 im-

age remains, the monitor should be turned off for one hour to erase the image.

  NOTE: As with all personal display devices, NEC Display Solutions of America, Inc.

recommends  displaying moving images or using a moving screen saver at regular 

intervals whenever the screen is idle or turning off the monitor when not in use.

•  Signal cable should be completely attached to the computer.

•  Use the OSD Image Adjust controls to focus and adjust display by increasing or de-

settings may need to be readjusted.

•  Check the monitor and your display card with respect to compatibility 

and recommended signal timings.

•  If your text is garbled, change the video mode to non-interlace and use 60Hz refresh rate.
