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, 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 displaying
moving images and using a moving screen saver
at regular intervals whenever the screen is idle or
turning off 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. Please set
the LONG CABLE COMP in that case. 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.
