(e.g., DVD player, video game system, set-top
box, etc.) try using a

connection instead.
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.
