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 A/V 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.
