Image persistence
¥Please be aware that LCD Technology may experience a phenomenon known as Image Persistence. Image Persistence occurs when a residual or ÒghostÓ image of a previous image remains visible on the screen. Unlike CRT monitors, LCD monitorsÕ 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.
