You can watch select TV shows and movies on Netflix in 5.1 surround sound. Titles that have 5.1 surround sound available will display either a Dolby Digital Plus icon or a 5.1 icon on the movie description page.
To stream with 5.1 surround sound, you need:
A 5.1 surround sound-capable audio system.
A Netflix-capable device with 5.1 surround sound support.
Streaming quality set to Medium, High, or Auto.
If you meet these requirements but aren't receiving 5.1 surround sound, see some troubleshooting steps.
