Troubleshooting - NEC MultiSync LCD1980FXi Mode D'emploi

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.
• Make sure the Vacation Switch is in in the ON position.
• 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 recommended settings.
• Check the signal cable connector for bent or pushed-in pins.
• Check the signal input, "INPUT 1" or "INPUT 2".
• Ensure the DVI input mode is set to DIGITAL when the MAC digital output is connected to the DVI-I (Input1) connector.
Power Button does not respond
• Unplug the power cord of the monitor from the AC outlet to turn off and reset the monitor.
• Make sure that the Vacation Switch on the left side of the monitor is in the ON position.
Image persistence
• Please be aware that LCD Technology may experience a phenomenon known as Image Persistence. Image Persistence occurs
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 image remains, the monitor should be turned off for one hour to erase the
image.
NOTE:
As with all personal display devices, NEC DISPLAY SOLUTIONS recommends displaying moving images
and using a moving screen saver at regular intervals whenever the screen is idle or turning off the monitor when
not in use.
Message "OUT OF RANGE" is displayed (screen is either blank or shows rough images only)
• Image is displayed only roughly (pixels are missing) and the OSM warning "OUT OF RANGE" is displayed: Either signal clock
or resolution is too high. Choose one of the supported modes.
• OSM warning "OUT OF RANGE" is displayed on a blank screen: Signal frequency is out of range. Choose one of the
supported modes.
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 the display by increasing or decreasing the Fine total. 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 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.)
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 tilt
• Rotate the screen to 90° clockwise until you hear one click.
• Refer to the Quick Start section, "Remove monitor stand for mounting" to insure correct installation of stand.
