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.
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
