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 the screen's service life: It is normal and not indicative of
malfunctioning.
The unit digitally processes the various signals in order 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 the input has been switched.
Due to characteristics of the system used to drive the liquid crystal
panel, the edges may appear to flicker in the fast-moving parts of the
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
dissappear when a general moving picture is displayed for a while.
This is not considered as malfunction.
This LCD Display uses special image processing, Hence a slight time
lag may occur between image and audio depending on the type of
input signal, However, this is not a malfunction.
