Troubleshooting No picture • The signal cable should be completely connected to the display card/computer. • The display card should be completely seated in its slot. • Power Switch and computer power switch should be in the ON position. • Check to make sure that a supported mode has been selected on the display card or system being used.

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.
