Troubleshooting
No picture
•฀ Make฀sure฀the฀signal฀cable฀is฀fully฀connected฀to฀both฀the฀monitor฀and฀the฀computer.
•฀ Make฀sure฀the฀computer’s฀display฀card฀is฀fully฀seated฀in฀its฀slot.
•฀ Do฀not฀use฀a฀DisplayPort฀converter฀adapter.฀This฀device฀is฀not฀supported.
•฀ Make฀sure฀both฀the฀computer฀and฀monitor฀power฀switches฀are฀in฀the฀ON฀position.
•฀ The฀monitor฀will฀automatically฀turn฀off฀by฀the฀[POWER฀SAVE฀TIMER]฀function฀when฀the฀[POWER฀SAVE฀TIMER]฀setting฀is฀
[ON] and continues power save mode for 2 hours. Please touch the [ ] key.
•฀ Make฀sure฀that฀a฀Major฀Supported฀Timings฀has฀been฀selected฀for฀the฀display฀card฀in฀the฀system฀being฀used.
(Please consult the manual for the system or display card for supported resolution and changing the settings.)
•฀ 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.
•฀ Make฀sure฀the฀connected฀device฀outputs฀a฀signal฀to฀the฀monitor.
•฀ If฀the฀front฀LED฀is฀dark฀blue,฀check฀the฀status฀of฀the฀[OFF฀MODE฀SETTING]฀mode฀(see฀
page 14 ) or [HUMAN SENSING]
(see page 14 ).
Power Key does not respond
•฀ Unplug฀the฀monitor’s฀power฀cord฀from฀the฀AC฀outlet฀to฀reset฀the฀monitor.
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)
•฀ OSD฀warning฀“OUT฀OF฀RANGE”฀is฀displayed฀on฀a฀rough฀image฀(pixels฀are฀missing):฀Either฀the฀signal฀clock฀or฀resolution฀
is too high. Change the settings to a supported mode.
•฀ OSD฀warning฀“OUT฀OF฀RANGE”฀is฀displayed฀on฀a฀blank฀screen:฀The฀signal฀frequency฀is฀out฀of฀range.฀Change฀the฀
settings to a supported mode.
Image is unstable, unfocused or swimming is apparent
•฀ Signal฀cable฀should฀be฀completely฀attached฀to฀the฀computer.
•฀ Disconnect฀the฀DisplayPort฀cable฀and฀touch฀the฀[MENU]฀key.
Select [DP LONG CABLE] then adjust the OSD value using the [ ] key or [ ] key.
•฀ Use฀the฀OSD฀Image฀Adjust฀controls฀to฀focus฀and฀adjust฀the฀display฀by฀increasing฀or฀decreasing฀the฀[FINE]฀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฀the฀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฀the฀[LED฀BRIGHTNESS]฀adjustment.
Picture is not bright
•฀ If฀the฀brightness฀fluctuates,฀make฀sure฀[DV฀MODE]฀is฀set฀to฀[STANDARD].
•฀ Make฀sure฀[ECO฀MODE]฀and฀[AUTO฀BRIGHTNESS]฀are฀turned฀off.
•฀ If฀the฀brightness฀fluctuates,฀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.
•฀ Make฀sure฀that฀a฀Major฀Supported฀Timings฀has฀been฀selected฀for฀the฀display฀card฀in฀the฀system฀being฀used.
(Please consult the manual for the system or display card for supported resolution and changing the settings.)
•฀ When฀using฀an฀HDMI฀input,฀please฀change฀[OVER฀SCAN].
