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

Check the monitor and your display card with respect to compatibility and recommended settings.

Check the signal cable connector for bent or pushed-in pins.

Check the signal input, “INPUT 1” or “INPUT 2”.

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 Electronic Displays recommends using a screen saver at regular intervals whenever the screen is idle.

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 total. When the display mode is changed, the OSM Image Adjust settings may need to be re- adjusted.
