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/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.
