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 cable connector for bent or pushed-in pins.

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 ÒghostÓ image of a previous image remains visible on the screen. Unlike CRT monitors, LCD monitorsÕ 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.

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 control. When the display mode is changed, the OSM 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 green 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 OSM 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).
