External 

Speaker

Adjusts how the sound is synced from external speakers, such 

as an external speaker connected to the digital audio output 

port, LG audio device and headphone.

The "-" button makes the sound output faster and the "+" 

button slower than the default value.

 

✎ LG audio device is supported only for models with the 

optical digital port.

Bypass

Outputs broadcasting signals or the audio of an external 

device without audio delay. Audio may be output before video 

as it takes time to process video input into the TV.
