Cast content from your phone, tablet, or browser to Google TV

Every Google TV device has a built-in Cast receiver, letting you send video, audio, or a Chrome tab from a phone, tablet, or computer directly to the TV without opening an app on the TV itself first.

What you should know

  • Make sure the casting device (phone or laptop) is on the same Wi-Fi network as the Google TV device — casting doesn't work across separate networks or with guest network isolation enabled on the router.
  • In a supported app (YouTube, Netflix, etc.), tap the Cast icon and select your Google TV device's name from the list.
  • To cast an entire phone screen or a Chrome browser tab, use the Cast option in Chrome's menu or your phone's Quick Settings "Screen cast" tile, which mirrors rather than streams natively.

Why it matters

Casting failures are overwhelmingly a network issue — router client (AP) isolation, band steering that puts devices on different bands, or a VPN active on the phone — rather than a problem with the Google TV device or the app, so checking the network setup first saves a lot of troubleshooting.

Best practices

  • Disable client or AP isolation on your router's guest network if you cast from a device connected there — isolation blocks the local discovery casting depends on.
  • Keep the Google TV device's display name unique and recognizable under Settings → Device Preferences → About → Device name, especially in a home with multiple Cast targets.
  • Turn off any active VPN on the phone or laptop before casting, since VPNs frequently route traffic off the local network and break device discovery.

Common problems and fixes

Cast icon doesn't appear or device isn't found
Confirm both devices are on the same Wi-Fi network and band, and that the router doesn't have client isolation enabled; restarting both devices' Wi-Fi also clears most discovery failures.
Casting starts but video is choppy or lags
This is usually Wi-Fi bandwidth on the casting device's network hop, not the TV — move the router closer, switch to 5GHz, or reduce other network traffic during casting.

Tips and tricks

  • Chromecast built-in and the Google TV Cast receiver both let you queue multiple items from a Cast-enabled app before the current one finishes, so you don't have to keep the phone active for playlist casting.

Frequently asked questions

Do I need the Google Home app to cast?

No — casting is built into the Cast-enabled app itself (YouTube, Spotify, Chrome, etc.); the Google Home app is only needed for device setup and Wi-Fi management, not for everyday casting.
