NOTE 1: IMAGE PERSISTENCE
y
Please be aware that LCD Technology may experience a phenomena known as Image Persistence. Image Persistence
occurs when 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.
y 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.
y As with all personal display devices, ViewSonic 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.
Please set “POWER SAVE”, “SCREEN SAVER”, “DATE &TIME” and “SCHEDULE” functions to further reduce the risk
of Image persistence.
