Poor composite or S-video picture

connected to an external A/V device (e.g.,
DVD player, video game system, set-top
box, etc.) try using a ColorStream video
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 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.
