to turn off and reset the monitor.
•฀Check฀the฀main฀Power฀Switch฀on฀the฀monitor.
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, the image persistence of LCD monitors is
not permanent, but single still image being displayed for a
long period of time should be avoided. To alleviate image
persistence, put the monitor into standby via remote
control or turn the monitor’s main power off 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 in standby or main
power off for one hour to erase the image.
NOTE: As with all personal display devices, NEC
DISPLAY SOLUTIONS recommends displaying
moving images, using a moving screen saver, or
changing still images at regular intervals whenever
the screen is idle, or turning it into standby or main
power off of the monitor when not in use.
The image is blinking
•฀If you use a signal repeater or distributor or a long
cable, this may cause image roughness or blink for a
moment. In this case please connect the cable to the
monitor directly without using a repeater or a distributor,
or replace the cable with a higher quality cable. Using
a twisted pair extender may cause image roughness
depending on the environment where the monitor is in or
the cable you are using. For further information please
ask your supplier.
•฀Some HDMI cables may not show a correct image.
If input resolution is 1920 x 2160, 3840 x 2160 or
4096 x 2160, please use a HDMI cable which is approved
to support 4K resolution.
The image is unstable, unfocused or swimming is
apparent
•฀The฀signal฀cable฀should฀be฀completely฀attached฀to฀the฀
computer.
•฀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 re-adjusted.
•฀Check฀the฀monitor฀and฀your฀display฀card฀with฀respect฀to฀
compatibility and recommended signal timings.
•฀If฀text฀looks฀garbled,฀change฀the฀video฀mode฀to฀non-
interlaced and use a 60 Hz refresh rate.
•฀The฀image฀may฀be฀distorted฀when฀turning฀the฀power฀on฀or฀
changing the settings.
The image of component signal is greenish
•฀Check฀to฀see฀if฀the฀VGA (YPbPr) input connector is
selected.
LED on the monitor is not lit (no blue or red color can be
seen)
•฀The฀main฀Power฀Switch฀should฀be฀in฀the฀ON฀position฀and฀
the power cord should be connected.
•฀Make฀certain฀the฀computer฀is฀not฀in฀a฀power-saving฀mode฀
(touch the keyboard or move the mouse).
•฀Check in the OSD that the power indicator option is set to
ON.
LED colors, except for blue, are blinking or glowing
•฀A certain failure might have occurred, please contact your
supplier.
•฀If the monitor is powered off by the internal temperature
being higher than the normal operating temperature,
the LED will blink green or amber or red for six times.
Power on the monitor again after confirming the internal
temperature has been reduced to normal operation
temperature.
•฀The monitor could be in standby.
Press the power on button on the remote control or press
the power button on the monitor.
The image is not properly reproduced
•฀Use฀the฀OSD฀Image฀Adjust฀controls฀to฀increase฀or฀
decrease the coarse adjustment.
