have no adverse effect on the TV’s performance.
Avoid touching the LCD screen or holding your
finger(s) against it for long periods of time. Doing
so may produce some temporary distortion
effects on the screen.
-
This panel is an advanced product that contains
millions of pixels. In a very few cases, you could
see fine dots on the screen while you’re viewing
the TV. Those dots are deactivated pixels and
do not affect the performance and reliability of
the TV.

Displaying a still image for a prolonged period
of time may cause an image sticking. Avoid
displaying a fixed image on the TV screen for an
extended length of time.
