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.

•The monitor does not support DisplayPort converter signal.

•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, “DVI-D”, “DisplayPort”, “HDMI” or “D-Sub”.

•If the front LED is dark blue, check the status of the OFF MODE SETTING mode (see page 12) or Human sensor (see page 12).

•When using an HDMI input, please change “OVER SCAN”.

Power Key does not respond

•Unplug the power cord of the monitor from the AC outlet to turn off and reset the monitor.

•When something is stuck on the bezel, key becomes unresponsive.

Image Persistence

•Image persistence is 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 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 OSD warning “OUT OF RANGE” is displayed: Either signal clock or resolution is too high. Choose one of the supported modes.

•OSD 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 OSD Image Adjust controls to focus and adjust display by increasing or decreasing the fi ne adjustment. When the display mode is changed, the OSD 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 blue or amber color can be seen)

•Power Switch should be in the ON position and power cord should be connected.

•Increase LED BRIGHTNESS adjustment.

Picture is not as bright

•Make sure ECO MODE and AUTO BRIGHTNESS are turned off.

•If the brightness fl uctuates make sure AUTO BRIGHTNESS is turned off.

•Signal cable should be completely attached.

•LCD brightness degradation occurs due to long-term usage or extreme cold conditions.

•When using an HDMI input, please change “VIDEO LEVEL”.

Display image is not sized properly

•Use the OSD Image Adjust controls to increase or decrease the Coarse adjustment.

•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.)

•When using an HDMI input, please change “OVER SCAN”.

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).

•Some video cards do not output video signal when monitor is turned OFF/ON or disconnect/connect from the AC power cord under low resolution with DisplayPort.

•When using an HDMI input, please change “OVER SCAN”.
