Picture and sound are out
of
sync
• As with all products that contain a digital display,
in
rare instances, when viewing certain content
(e.g
..
television broadcasts, video games, DVDs),
you may notice that the sound and picture are
slightly out
of
sync. This phenomenon can be
caused by various factors including, without
limitation, video processing within the
TV,
video
processing
in
an attached gaming system, and
video processing or different compression rates
used by broadcasters in their programming.
You
may want to try one or more
of
the following
suggestions, which may help to reduce the effect
of
this phenomenon:
-
If
the TV
is
connected to an
AN
receiver that
has a programmable audio delay feature, use
this feature to help synchronize the sound to
the picture.
-
If
you notice this phenomenon only on
certain TV channels, please contact your
local broadcast, cable, or satellite provider to
inform them
of
this issue.
