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

of
the following
suggestions, which may help to reduce the

-
If

this feature to help synChronize the sound to

- If you notice this phenomenon only on
certain
TV
channels, please contact
