Image persistence
• Image persistence is when a "ghost" of an image remains on the screen even after the
monitor has been turned off. Unlike CRT monitors, LCD monitors' 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 monitor for one hour and a "ghost" of
that image remains, the monitor should be turned off for one hour to erase the image.
NOTE: As with all personal display devices, NEC-Mitsubishi Electronics Display of America
recommends using a screen saver at regular intervals whenever the screen is idle.
Image is unstable, unfocused or swimming is apparent
• Signal cable should be completely attached to the computer.
• Use the OSM Image Adjust controls to focus and adjust display by
increasing or decreasing the fine total. When the display mode is changed, the OSM
Image Adjust settings may need to be re-adjusted.
• Check the monitor and your display card with respect to compatibility
and recommended signal timings.
• If your text is garbled, change the video mode to non-interlace and use 60Hz refresh rate.

Display image is not sized properly
• Use the OSM Image Adjust controls to increase or decrease the Coarse total.
