How to Fix LG UltraWide Monitor Sound Not Working – HDMI/DP Audio, Output Device & Volume

Описание: In today’s video, we’re fixing the issue where your LG UltraWide monitor produces no sound, even though it’s connected through HDMI or DisplayPort. This happens when the audio device is wrong, the OSD audio source is muted, or the monitor isn’t receiving audio via the cable.

We start inside the OSD Audio menu, verifying that your monitor isn’t muted and ensuring the volume is turned up. Some LG UltraWide models default to “0% volume” after firmware updates.

Next, we move to Windows/macOS playback settings, where we select the LG monitor as the default audio output. I’ll show you how to test audio formats and fix apps that override global settings.

Then, we’ll confirm whether your HDMI/DP cable supports audio, because DisplayPort-to-HDMI adapters often drop sound completely. Direct connections always work best.

We’ll also troubleshoot cases where sound works on the desktop but not in:

YouTube

Games

Streaming apps

Consoles (PS5/Xbox)

Bonus tip: Some LG UltraWide monitors have a “Private Mode” toggle that temporarily disables speakers when headphones are detected — turning this off fixes many cases.
