As with all products that contain a digital display, in rare instances, when viewing certain content (e.g..television broad-
casts, video games, DVD), 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/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: Control-If
the TV is connected to an A/V receiver that has a programmable audio delay feature, use this feature to help synchro-
nize the sound to the picture.-If connected to a video game system and your TV has the Game Mode feature (see
owner’s manual for more information), enable this feature.-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.
