Image persistence
• Please be aware that LCD Technology may experience
a phenomenon known as Image Persistence. Image
Persistence occurs 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 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 displaying moving images
and using a moving screen saver at regular intervals
whenever the screen is idle or turning off the monitor
when not in use.
