Troubleshooting - NEC MultiSync LCD1525X User Manual

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 button and computer Power button 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.
• Check the DVI Selection in OSM.
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 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 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).
