LG 2017 OLED TVs get an audio update-- one providing customers with Dolby TrueHD lossless sound technology for what the company describes as "the ideal cinematic experience."
The update comes in the shape of an over-the-air firmware upgrade. All 2017 LG OLED TVs ship with Dolby AC-4 decoding, meaning compatible TVs can handle object-based next generation audio for immersive 3D experiences. Meanwhile premium 2017 LG TVs are Dolby Vision compatible, allowing customers to watch over 100 movies on streaming services with Dolby Vision support.
Another update addition is Codec MAT (Metadata-enhanced Audio Transmission) support, enabling Dolbly TrueHD audio bit streaming on compatible TVs when playing console games.
