A:Answer While it supports HDMI-ARC and Bluetooth, the bluetooth audio implementation is poor. High latency, no way to adjust timing, frequent disconnects, any time you turn the display on you have to hit buttons on the remote to tell it yes you want to reconnect to the Bluetooth device. Lacking an optical or 3.5mm out is astonishingly bad, when even many computer monitors have this (and all TVs will have at least the optical out).
In theory you can get an HDMI-ARC adapter to extract optical or analog audio, but then you've wasted one of just two HDMI inputs on the thing.
