	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, 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:
		• If the TV is connected to an external A/V device (e.g., DVD player, video
			game system, set-top-box, etc.) always try to use the Color Stream video
			jacks and corresponding audio jacks or the HDMI input (if available on your
			TV) for connection to such external A/V device.
		• 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 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 cetain TV channels, please contact
			your local broadcast, cable, or satellite provider to inform them of this issue.
