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 cables of Video input 1 or Video input 2 to make sure they are properly
connected. Then make sure the input select is set to the proper Video input.

Power Button does not respond

• Unplug the power cord of the monitor from the AC outlet to turn off and reset the
monitor, or simultaneously press the RESET and Power buttons.

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

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.)

Selected resolution is not displayed properly

• Use OSM Display Mode to enter Mode Change sub-menu and confirm that the
appropriate resolution has been selected. If not, select corresponding option.

USB Hub does not operate

• Check to make sure the USB cord is properly connected. Refer to your USB devise
User’s Manual.
