VIZIO 38” 5.1 Sound Bar System

Hi, I bought same type of Sound Bar Sys 3851-D0 before few days from woot, which has Ethernet / LAN connection too beside power&aux connectors on Soundbar. Does anyone know what it is for and how it can be configured and used ? It sounds so amazing, but setup was bit hard from manual supplied with it and not sure if I set it up properly. May someone pl. share some links which may help, to configure it on HDMI.


Can I pair this with Bluetooth headset and only hear the playback via my headset?
