depending on the type of input signal. However, this is not a malfunction.

between the video (output) equipment and twisted pair cable
transmitter and between the twisted pair cable transmitter
and this product.

The screen will darken slightly when photos, still images of
a computer or other pictures with minimal movements are
shown for an extended period. This is done to reduce image
retention on the screen and the shortening of he screen's
service life: It is normal and not indicative of malfunctioning.
The unit digitally processes the various signals in order
to reproduce esthetically pleasing images. As such, it
sometimes takes a few moments for the picture to appear
when the power has been turned on, when he input has
been switched.
Due to the characteristics of the system used to drive the
panel, the edges may appear to flicker in the fast-moving
parts of he images: This is normal and not indicative of
malfunctioning.
This is a characteristic of liquid crystal panels and is
not a problem. The liquid crystal panel is built with very
high precision technology giving you fine picture details.
Occasionally, a few non-active pixels may appear on the
screen as fixed points of red, blue, green, or black. Please
note this does not affect the performance of your LCD.
Image retention may occur. If you display a still picture for
an extended period, the image might remain on the screen.
However, it will disappear when a general moving picture is
displayed for a while. This is not considered as malfunction.
