What's the best streaming device for a home theatre?

The Apple TV 4K is the top pick for a home theatre thanks to its excellent Dolby Vision and Atmos support, polished apps and smooth performance. The NVIDIA Shield TV Pro is the alternative for its powerful AI upscaling and Plex strengths. Both output 4K HDR and Atmos to a good AV receiver or soundbar, which is what a home cinema needs.

Do I need an AV receiver or a soundbar?

Either works; it depends on your budget and space. An AV receiver with surround speakers gives the most immersive, true surround-sound home cinema. A premium Dolby Atmos soundbar is simpler and cheaper while still delivering excellent, room-filling sound. Both should support the audio formats your streaming device outputs, especially Dolby Atmos, via HDMI eARC.

What HDMI cable do I need for a home theatre?

Use an Ultra High Speed HDMI cable (HDMI 2.1) for a home theatre. It carries 4K at high frame rates, full HDR including Dolby Vision, and Dolby Atmos passthrough without bandwidth limits, and it's needed for eARC to send Atmos from the TV to a receiver or soundbar. Certified cables avoid the dropouts and format failures cheaper cables can cause.

How do I set up Dolby Vision and Atmos for streaming?

Set your streaming device to output the highest video format your TV supports (4K Dolby Vision), and enable Dolby Atmos in its audio settings. Connect audio via HDMI eARC to your receiver or soundbar, and make sure the TV input is in its enhanced/full-colour mode. Match content — Apple TV's 'Match Content' helps — so each title plays in its native format.

What settings give the best home-theatre picture?

Use a Cinema or Filmmaker picture mode, enable the HDMI input's enhanced/full-colour mode for proper HDR, set the device output to 4K Dolby Vision, and avoid Vivid presets that clip highlights. For sound, enable Dolby Atmos and use eARC. These settings, on capable hardware, deliver the reference-quality look and sound a home theatre is built for.
