How to fix sound delay on projector

If you use a projector for your presentations or other important events, you want to make sure that your audience can hear you. You also want to make sure that the sound is not delayed if you are watching movies on a projector. Because there is nothing more frustrating than having to deal with delayed sound while watching the media.

If you are speaking, and someone in the audience is responding at the same time, you have a problem. While the problem could also be in the speakers, most of the time, it is in the projector. More particularly, the problem is a sound delay in your projector. Read on, if you want to know how to fix sound delay on a projector.

Diagnosing the Problem

When trying to fix the projector Bluetooth audio delay problem, it is essential to identify the device setting that is causing the problem. There are two types of settings for this device. They are called Audio Delay and Digital Audio Delay. The former deals with the delay applied to the audio signal of live video, whereas digital audio delay deals with the uncertainty applied to stored video.

What is the sound delay?

The sound delay is a setting on some projectors that can be adjusted to synchronize the audio and video. It’s usually set to a 20-30 ms default but can be changed with a simple push of a button. It has the effect of a time difference between when the audio is played and when it is heard. If the audio is delayed, you can listen to an echo effect. It will not be noticeable if the delay is just a few milliseconds (ms). Still, if the delay is significant (more than a few milliseconds), then the delay will be pretty noticeable.

Potential causes of the problem

When there is a sound delay on your projector, it can cause off-sync audio and video problems, making it difficult to hear or see the presentation. Several potential causes for the issue include the projector itself malfunctioning or connecting cables not being connected properly.

Another major reason that can cause the sound or audio delay on a projector is the change in settings of the projector. As mentioned earlier, projectors have a sound delay setting which can be set to a difference of several seconds to a few minutes. If the setting is set to even a single second, the audio delay between the picture and the sound becomes noticeable.

How to fix sound delay on a projector?

Sound delay, also known as lip-syncing error, is irritating for normal people, but people who are hearing impaired cannot even understand what they watch. Fortunately, there are several methods that users can use to fix the audio or sound delay problem. One way is to set up the projector to receive sound directly from an HDMI cable rather than through the typical audio jack. An inaccurate connection of the audio jack can cause a sound delay which can be fixed by using the more accurately connecting HDMI jack.

If the sound delay on the projector is not fixed after properly connecting the audio jack or the HDMI jack, you will need to adjust the delay settings. To do so, you will need to go to the settings option of the projector. Then open the sound or audio delay settings. In it, make sure that the sound delay setting is set to 20-30 ms. If this setting is set to anything other than this value, you will need to change it.

Types of sound delay

There are two types of sound delay. The first is the one in which the sound plays after the picture. And in the second one, the audio plays before the picture. To adjust the sound delay settings for both types, there are different rules:

Audio plays after the picture

If the audio plays before the picture on your projector, you will need to set the delay settings to a minimum. If it is set to 50 ms (milliseconds), set it to 40 or 30 ms, depending on the duration of the delay. Then play something and check whether the audio and the lips of the characters are synchronized. If not, readjust the settings until the picture and the audio are in sync.

Audio plays after the picture

If you see the picture first and then the audio plays on your projector, you will need to readjust the sound delay settings in the opposite manner to the above-mentioned. Simply set the audio delay settings to a higher value. For example, if the preset value is 10 ms, reset it to 20 or 30. Then check if the picture and the audio are in sync. Keep readjusting the setting in the same manner until your picture and audio are synchronized.

Conclusion

Sound delay is a common issue that is common with projectors. But it is possible to fix it. You can either check the cables and make sure that they are connected perfectly. Or you can change the sound delay settings unless the audio and the picture are synchronized.

When using a projector, it is essential to ensure that the sound and video are synced. It can be accomplished by making sure the sound on the computer matches the sound coming through the speakers. If there is a delay on both sides of this equation, there will be an out-of-sync video and audio projected on the screen, which can be very annoying to those watching. Fortunately, fixing this issue is easy and requires little effort.

FAQs

How to fix projector lag?

If the video is playing too quickly or too slowly, the audio will be out of sync with the video. You can fix this by adjusting the projector’s audio delay settings.

How do I fix the HDMI audio delay?

For those not familiar, HDMI cables transmit both video and audio signals. Sometimes it takes a few seconds for the signal to go from the projector to your receiver or speakers, which can cause a sound delay. To fix this issue, first, make sure that the cable is connected properly. If the problem persists, adjust the audio delay settings of the projector.
