Image Retention

image retention on the screen.

NOTE: IMAGE PERSISTENCE
• 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.
• 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.
• 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 use the Power Save and Schedule functions to further reduce the risk of Image
persistence.
Auto Adjustment
• Use this function to let the LCD monitor automatically optimize the display of PC or YPbPr input
image.
• Press ENTER button to execute this function.
