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 the LED of AC adapter is ON.
• 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.
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 “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 Electronics Display 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 OSD Image Adjust controls to focus and adjust display by increasing or decreasing the fine total. When the
display mode is changed, the OSD Image Adjust settings may need to be re-adjusted.
• 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 colour can be seen)
• Power Switch should be in the ON position and power cord should be connected.
• Check the LED of AC adapter is ON.
• Make certain the computer is not in a power-saving mode (touch the keyboard or mouse).
Display image is not sized properly
• Use the OSD Image Adjust controls to increase or decrease the Coarse total.
• 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.)
Selected resolution is not displayed properly
• Use OSD Display Mode to enter Information menu and confirm that the appropriate resolution has been selected. If not,
select corresponding option.
