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, the image persistence
on LCD monitors is not permanent, but single still image 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.

OTEE:

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.
