How to fix audio delay issues when using LG’s game optimizer mode

Switching the audio output to the TV speaker should help fix the audio delays when you are using the game optimizer mode on your LG B1, C1, G1, B2, C2 or G2.

In order to switch audio output, you can try doing the following:

How to fix audio delay issues for external audio device when using LG’s game optimizer mode

If you want to keep using your earphones, headphones, speaker or soundbar with the game optimizer mode turned on for your LG television set, then you can try taking the following steps:

1. Go to the Settings menu of your B1, C1, G1, B2, C2 or G2.

2. In the Settings menu, go to the Sound submenu.

3. Inside the Sound submenu, select Advanced Settings.

4. Next, you need to go to the “Select HDMI Input Audio Format” option.

5. Make sure you set “Select HDMI Input Audio Format” to PCM.

If you are still experiencing audio delays while using an external audio device even after switching to the PCM format in the game optimizer mode, then you can try the following potential solutions:

  • If you are using a wireless sound output device, then you need to make sure that there aren’t any physical objects, as well as other wireless devices, that may be weakening the signal.
  • If you are using a wired sound output device, then you should make sure that you are using the recommended HDMI or optical cable for the device and your television set.
  • If you are using HDMI to connect your external sound output device, then you need to make sure that the HDMI connection is passing through correctly, especially if you are connecting it to a splitter or another passthrough device, as each junction may introduce audio delay.
  • Keep in mind that wireless listening devices will introduce more audio lag when compared to wired listening devices.
