How To Fix Sound Delay On A Projector?


There are quite a few things that can get in the way of how much you enjoy a digital viewing experience while using your beloved projector, and any type of lag is at the top of the list. 

For example, you could suddenly get some type of sound delay while watching a movie on your projector, and it will take so much away from the fun you were having that you will stop watching it altogether. 

What can you do about that?

In this article, we discuss the possible causes of projector sound delay and what you can do about it.

Why am I Getting Sound Delay?

Sound delay

Understanding sound delay is not very difficult, especially when you experience it while using a projector, but understanding why it is happening can be. 

Sound delay occurs when the sound comes slightly after the action that it corresponds to. This could happen when you are watching a film, playing a video game, or even when making a presentation at work.

We can safely assume at this point that there is a particular part of the projector or any device that it is attached to that is malfunctioning in some way; this could be a hardware or software issue. 

That sounds simple enough, but getting to the actual cause and fixing it is going to take a few steps.

The Simplest Solution of All

Now, while people’s frustration when they suddenly experience projector sound delay while watching an exciting movie or show that they have been dying to watch or playing a brand new video game is perfectly understandable, it is far worse during a presentation.

Being in front of your colleagues when this happens can feel devastating, but there is no need to panic because there is bound to be a solution.

The simplest possible solution is this: check the volume.

Whether your projector is connected to a computer or another device such as a console, the volume settings might have suddenly gone awry. 

This simple step might well save you a lot of time checking other things so, even if it seems like a long shot, it is worth doing before anything else.

If the sound settings on your connected device seem to be just fine, There are a few other things to check:

  • The battery – If the device you have connected to your projector happens to be a console or something else directly connected to an outlet, there is no need to worry about a battery; but that is what needs to be checked if we are talking about a laptop. Your laptop’s battery might have suddenly dropped to a critical level and that could have caused the sound delay you are experiencing. 
  • Overheating Issues – Overheating can cause a laptop and plenty of other electronic devices to act erratically, even causing sound delay and other issues as well. Make sure that your device is not overheating. If it is abnormally hot, you might want to shut it down for a bit and make sure that it is properly ventilated when you turn it back on. 
  • OS Update – Even if your device had been working without showing any signs of sound delay up to this point, the sudden issue could be because the operating system is out of date. Check for OS updates and update accordingly.
  • Cable – Assuming that your device is not connected to your projector via WiFi, check the cable that connects it to the projector. Try a different cable if you have one, then try a different port on the projector. 

If all of this is working properly, it is time to check the projector itself.

Checking Your Projector 

Adjusting the projector

The first thing to consider here is whether you have recently dropped your projector or hit it with something accidentally. If anything like that has happened, it could be the cause and the best thing to do is to take it in for repairs.

Just as the device that is directly connected to your projector could be overheating, so could your projector be for one of various reasons. 

Check to see whether your projector is too hot or not; if it is, turn it off for a while. When you turn it back on, make sure to place it in a place where it will get sufficient ventilation. If it continues to overheat, your projector could use maintenance to clean it properly.

If your projector was not dropped, physically damaged in any other way, and is not overheating, the problem probably has to do with settings or software. 

As you probably already know, not all projectors are made to project images of the same quality or produce the same sound quality. You might be trying to output content that your projector might not be able to or is not properly set up to do. 

Go into your projector settings to ensure that they are properly configured for what you are doing. Projector sound settings can vary from one particular brand and/or model to another so it is best to consult your user manual for this.

Keep in mind that the user manual for your projector should be available online or through customer service if need be.

Using Apps

Projectors have come a long way from when they were first invented; some even allow us to install different types of wonderful apps on them now! 

If you happen to be using an app that is either installed directly on your projector or on the device that it is connected to. In that case, you will definitely want to make sure that the issue you are having with audio delay is not being caused by this app.

The first thing you can do here is to close the app entirely and try your projector differently or with a different app that you normally use. If everything suddenly works fine, then the issue was obviously with the app in question.

You can try updating the app that caused the problem to see if that eliminates the issues; if not, try reinstalling all together. If the problem still persists, you might want to consider using a different app that does the same thing. 

Contact Customer Support

If none of the solutions that we have gone through here work for you, you can always reach out to the customer support department for your projectors manufacturer for assistance. This, of course, assuming that your projector is still under warranty; if not, you will have to go to a repair shop.

Conclusion

No one would disagree that sound delay can ruin a movie, game, or presentation very quickly. However, there are quite a few things that can be checked and solutions to try to resolve the issue as quickly and painlessly as possible. Failing that, service and repairs are always an option. To conclude, remember to always have proper maintenance performed on your projector regularly to keep it working as best as possible.
