The more input lag, the harder it is to make well-timed shots in games like first-person shooters. This is the amount of time it takes for a command entered on a controller (a button press, say) to show up on the screen. If you're a gamer, you've likely heard of input lag. If your problem is in the TV, there are a few options to try: Game mode/input lag A TV with Game mode can help test for lip-sync error. If so, then you've found the culprit: the receiver.įiguring out where the problem is coming from makes it a lot easier to see if you can fix it without buying new gear. If you have a receiver in the mix, connect a source directly to the TV, and see if the problem disappears. This may seem obvious, but I've gotten emails from people angry at everything but their new TV for causing lip-sync issues. If your sources (Blu-ray player, cable box, and so on) are connected directly to your TV, and every source has a lip-sync problem, then the TV is the offender. If you're seeing errors only on certain channels, or with certain programs, it's probably not the fault of your system. If the problem is in the program you're watching, there's not much you can do about it (though don't miss the Receiver/Sound bar section below). Tracking down where the sync issue is coming from is a good first step. Other people don't notice the delay until it becomes more severe. Some are sensitive enough to notice lip-sync errors of just a few frames - small fractions of a second. People's perception of the problem also varies. There are many causes of lip-sync errors, but for the purpose of this article we'll concentrate on the ones you can potentially do something about: those caused by your own AV gear. Sometimes you can fix the issue, but all too often you can't.
It can be annoying, to say the least - the kind of thing that once you notice, you can't forget about easily. Most commonly the video lags behind the audio, but the reverse can also happen. This can make it look like someone else is doing the voices on your movie, like a badly dubbed foreign-language film. A lip-sync error occurs when the video of a person speaking on your TV doesn't match up with the sound of them speaking.
