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, 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, 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 and using a moving screen saver
at regular intervals whenever the screen is idle
or turning it into standby or main power off of the
monitor when not in use.
Image is blinking
• If you use a repeater, distributor, long cable, this may
cause image roughness or blink for a moment. If the
state of the screen is not improved, please connect the
cable to the monitor directly without using a repeater or a
distributor, or replace the cable of use.
• Some HDMI cable may not display an image correctly.
If input resolution is 1920 x 2160, 3840 x 2160 or
4096 x 2160, please use the HDMI cable that supports
4K resolution.

Adjust settings may need to be re-adjusted.
• Check the monitor and your display card with respect to
compatibility and recommended signal timings.

interlace and use 60Hz refresh rate.
• The image may be distorted when turning the power on or
changing the settings.
