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.

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.)

Check the monitor and your display card with respect to compatibility and recom- mended settings.

Check the signal input.

Check to make sure that correct input source is selected.

Power Button does not respond

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

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 im- age remains, the monitor should be turned off for one hour to erase the image.

NOTE: As with all personal display devices, NEC Display Solutions of America, Inc. recommends displaying moving images or using a moving screen saver at regular intervals whenever the screen is idle or turning off the monitor when not in use.

Image is unstable, unfocused or swimming is apparent

Signal cable should be completely attached to the computer.

Use the OSD Image Adjust controls to focus and adjust display by increasing or de- creasing the FINE control. When the display mode is changed, the OSD Image Adjust settings may need to be readjusted.

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.

LED on monitor is not lit (no blue or amber color can be seen)

• Power Switch should be in the ON position and power cord should be connected.

Display image is not sized properly

Use the OSD Image Adjust controls to increase or decrease the H.SIZE.

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.)

No Video

If no video is present on the screen, turn the Power button off and on again.

Make certain the computer is not in a power-saving mode (touch the keyboard or mouse).

No Sound

Make sure the speaker cable is proper connected.

Check to see if mute is activated.

Check the volume in the OSD menu.

No Sound from Headphones

• Make sure the headphones are properly connected.
