Poor Sound Quality – Sound Test

  • Troubleshooting

Poor Sound Quality – Sound Test

You can check the product for any abnormalities by performing a sound test.
If the voice in the sound test sounds normal, it may be a problem with the broadcasting signal, not the product.
Contact your service provider. (Wired, cable, Sky life, IPTV, etc.)
If the voice in the sound test does not sound normal, it is necessary to have the monitor checked by an LG service technician for an accurate diagnosis.

Note
If there is no settings [Settings] button on the remote control, you can access the Settings menu by pressing the home button among the buttons on the remote control.
