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.

• The monitor does not support DisplayPort converter signal.

• Front 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.

(Please consult display card or system manual to change graphics mode.)

Power Key does not respond

• Unplug the power cord of the monitor from the AC outlet to turn off and reset the monitor.

• When something is stuck on the bezel, key becomes unresponsive.

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 DISPLAY SOLUTIONS recommends using a moving screen saver at
