Set up Apple TV
To use Apple TV, you need:
A high-definition or 4K TV with HDMI
An HDMI cable to connect Apple TV to your TV (for 4K HDR, you may require a compatible Ultra High Speed HDMI cable, sold separately)
Access to an 802.11 wireless network (wireless streaming requires 802.11a, g, n, or ac) or an Ethernet network and broadband internet
An Apple ID for purchasing and renting, downloading apps from the App Store, and using Home Sharing
To take full advantage of Apple TV 4K’s audio and visual capabilities, you’ll need a TV that supports 4K, HDR, and Dolby Vision, and a sound system that is Dolby Atmos–compatible.

Set up Apple TV
Before you start, make sure you know your wireless network name (and password if the network is password-protected). If you’re using a wired network, use an Ethernet cable to connect your Apple TV.
Connect one end of an HDMI cable to the HDMI port on your Apple TV, then connect the other end to the HDMI port on your TV.
Connect one end of the power cord to the power port on your Apple TV and the other end to a power outlet.
Turn on your TV, then select the HDMI input that’s connected to your Apple TV.
On some televisions, this may occur automatically.
Follow the onscreen instructions to set your internet connection, single sign-on, and other setup items.
See Set up single sign-on with your TV provider on Apple TV.
To use VoiceOver during setup, press the Back button
on the Siri Remote (2nd generation), or 
button on the Siri Remote (1st generation) three times. For more information, see Use VoiceOver on Apple TV.
Set up Apple TV automatically with an iOS or iPadOS device
Alternatively, you can transfer your Wi-Fi network and password and Apple ID account information automatically to Apple TV from an iOS device with iOS 9.1 or later, or from an iPadOS device with iPadOS 13 or later.
When the Apple TV setup screen appears, unlock your iOS or iPadOS device and make sure Bluetooth® and Wi-Fi are turned on.
Hold your device close to Apple TV and follow the onscreen instructions on your iOS or iPadOS device and Apple TV.
Note: Automatic setup doesn’t transfer account information for third-party apps such as Netflix or Hulu, and doesn’t turn on iTunes Match or Home Sharing.
Set up HDMI enhanced audio return channel on Apple TV 4K (2nd generation)
Apple TV 4K (2nd generation) includes eARC, which passes full-resolution audio—including 3D surround sound formats such as Dolby Atmos—from an eARC-supported TV (or any HDMI device connected to it) to your Apple TV.
For example, when you set up HomePod speakers with Apple TV 4K for home theater sound, you can use them to play audio from a game console that’s connected to your TV with an HDMI cable.
Note: eARC is currently a beta feature.
Connect one end of an eARC-compatible HDMI cable (sold separately) to the HDMI port on your Apple TV 4K, then connect the other end to the HDMI port labelled eARC on your TV.
Turn on your TV, then make sure its HDMI-CEC setting is enabled.
See the Apple Support article Make sure that HDMI-CEC is on.
Open Settings
on Apple TV 4K.Configure the HomePod (or HomePod stereo pair) as the default audio output for Apple TV.
In Settings on Apple TV, go to Video and Audio > Default Audio Output > Audio Return Channel (beta), then select Play Television Audio to turn eARC on.
On your TV, select the HDMI input for the device you want to route audio from (such as a game console or DVD player).
The audio for the selected device is routed through Apple TV to your HomePod speakers.
Note: You may need to check with your TV manufacturer to see if additional settings are required to enable eARC for audio output.
For more information, see the Apple Support article Use HDMI ARC or eARC with your Apple TV 4K (2nd generation).
