Nopicture

•The signal cable should be completely connected to the display card/computer.

•The display card should be completely seated in its slot.

•Check to make sure that a supported mode has been selected on the display card or system being used. (Please consult display card or system manual to change graphics mode.)

•Unplug the power cord of the monitor from the AC outlet for a minimum of 30 seconds to turn off and reset the monitor.

Image persistence

•Please be aware that LCD Technology may experience a phenomena known as Image Persistence.

•Image persistence is when a 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.

NOTE: As with all personal display devices, NEC-Mitsubishi Electronics Display recommends using a moving screen saver at regular intervals whenever the screen is idle or turning off the monitor when not in use.
