When playing my 65 inch 4K Sony TV I have serious lip sync issues. Even when the 4K Media player is directly connected to the TV via HDMI 4 and using the TV's own audio speakers the video lag is very pronounced. Not a pleasure to watch.
It occurs on all content in the 4K Media player as well as Net-Flix and other apps too. I can't find any lip sync adjustments in the TV's setup menu either.
There are a number of circumstances that can cause the audio and video to be out of sync:
If watching a TV program, it could be the broadcast itself or a bad connection between your cable/satellite set-top box (if applicable).
If a DVD or Blu-ray Disc® (BD) player is connected, a poor connection or the disc itself could be the cause.
When connected to a home theater system with a digital optical cable, then there may be an audio delay that requires a manually adjustment on the home theater system. There may even be a setting on the TV itself causing this issue.
NOTE: Because each of the steps below represent a possible solution to this issue, check if the issue is resolved after completing each step.
Make sure that the TV has the latest system software (firmware) installed.
Not all TVs have software that can be updated. To see if your TV can be updated, check the specifications, which are available through the Manuals/Specs/Warranty link on this page.
If the TV is connected to a high-speed Internet connection, a software update can be downloaded from the menu of the TV.
If the TV is not connected to the Internet, click on the Drivers and Software link to download the latest update.
If watching a TV program, try changing the channel to see if the problem occurs on other channels; if it only occurs on one channel, then the issue is with the broadcast.
NOTE: If the issue occurs on one channel only, contact the broadcast network provider.
Make sure all cables are securely connected to the TV and the source device (set-top box, DVD player, BD player, home theater system, or game console).
Try playing a different video source to determine if the issue occurs with other connected devices.
If your TV has a Game Modesetting, do one of the following:
Set the Game Mode to Off when watching TV or playing a DVD or BD.
Set the Game Mode to On when playing a video game.
If there is a home theater system and a digital optical cable is used in the connection, manually change the Audio/Video Sync or Audio Delay setting on the home theater system (if available).
Audio delay adjustments usually range from 0ms to approximately 250ms.
For information about the availability of A/V sync or Audio Delay setting, refer to the operating instructions supplied with the product. Manuals for Sony® products are available online through the Manuals/Specs/Warranty link on this page.
For a third-party home theater system, check the instruction manual or contact the manufacturer for information on how to adjust the A/V sync setting.
Please try these steps and let us know.
