Image persistence
• Image persistence is when a “ghost” image of an image remains on the screen even after the display has been turned off.
Unlike CRT monitors, LCD display’s image persistence is not permanent. To alleviate image persistence, turn the monitor
off for as long as an image was displayed. If an image was on the display for one hour and a “ghost” of that image remains,
the display should be turned off for one hour to erase the image.
NOTE:
As with all personal display devices, it is recommended to use a moving screen saver at regular intervals
whenever the screen is idle or turning off the monitor when not in use.
Message “OUT OF RANGE” is displayed (screen is either blank or shows rough images only)
• Image is displayed only roughly (pixels are missing) and OSD warning “OUT OF RANGE” is displayed: Either signal clock
or resolution is too high. Choose one of the supported modes.
• OSD warning “OUT OF RANGE” is displayed on a blank screen: Signal frequency is out of range. Choose one of the
supported modes.
