Casting to Google TV works through the same wireless connection as your Chromecast device

To cast to Google TV, your phone, tablet, or computer and your Google TV device must be on the same Wi-Fi network. Open the app or content you want to watch, tap or click the cast icon (it looks like a rectangle with curved lines in the corner), select your Google TV device from the list, and the content plays on your TV. The process takes about five seconds once you've connected both devices to the same network.

Google TV is built into certain TV models and streaming devices like the Google TV Streamer. If you have a standalone Chromecast with Google TV, the casting process is identical. Your phone or computer acts as a remote control — you can pause, rewind, or switch apps from your device while the content plays on the big screen.

Key Takeaways

  • Both your casting device and Google TV must be connected to the same Wi-Fi network before you can cast anything.
  • The cast icon appears in most streaming apps like YouTube, Netflix, and Spotify, but not all apps support casting.
  • Once you tap cast and select your device, your phone or computer can be put away — the content continues on your TV independently.
  • If the cast icon doesn't appear, check that both devices are on the same network and that your app is up to date.

Casting from an Android phone or tablet

Open the app with the content you want to watch — YouTube, Netflix, Spotify, or any other streaming service that supports casting. Look for the cast icon in the upper right corner of the app (a rectangle with three curved lines). Tap it, and a list of available devices appears. Select your Google TV device by name.

The content will start playing on your TV within a few seconds. Your phone screen returns to normal, and you can lock your phone, switch to another app, or put it down. Your phone is no longer controlling the playback — Google TV is. If you want to pause, rewind, or change the volume, open the app again and the playback controls will appear.

Casting from an iPhone or iPad

The process on Apple devices is the same as Android. Open your streaming app, find the cast icon (usually in the top right), and tap it. Select your Google TV device from the list. The content begins playing on your TV, and you can put your iPhone or iPad away.

Not all apps support casting from iOS devices — some apps like Apple TV+ and Apple Music do not have a cast button. For those apps, you may need to use AirPlay instead, which is Apple's wireless casting system. Check your app's settings or help section to see if casting is supported.

Casting from a Windows or Mac computer

On a computer, open Chrome browser and navigate to a website with video content, like YouTube.com. Click the three-dot menu in the upper right corner of Chrome, then select "Cast." A window appears showing available devices. Click your Google TV device, and the video plays on your TV.

You can also cast your entire computer screen or a single Chrome tab. To cast your whole screen, click the three-dot menu, select "Cast," then choose "Cast desktop" or "Cast tab" depending on what you want to share. This is useful for presentations, photos, or any content in your browser.

What to do if the cast icon doesn't appear

The most common reason the cast icon is missing is that your phone and Google TV are not on the same Wi-Fi network. Check your phone's Wi-Fi settings and make sure you're connected to the same network name as your TV. If you're on a guest network or a different band (2.4 GHz vs. 5 GHz), they may not see each other.

If both devices are on the same network and the cast icon still doesn't show, try closing and reopening the app. Some apps require an update to support casting — check your app store to see if an update is available. If the app is fully updated and the icon still doesn't appear, that particular app may not support casting.

Troubleshooting casting that starts but stops

If casting starts but the video keeps stopping or buffering, your Wi-Fi signal may be weak. Move your Google TV device closer to your router, or move your phone closer to the router while you're casting. A weak connection between your phone and the router can interrupt the casting signal.

If the video plays fine on your phone but stutters on the TV, the problem is usually your internet speed, not the casting connection itself. Casting uses very little bandwidth — the issue is that your TV is streaming the video directly from the internet, not from your phone. Restart your router by unplugging it for 30 seconds, then plug it back in and wait for it to reconnect.

Casting music and podcasts to Google TV

Spotify, YouTube Music, Apple Music, and most podcast apps support casting. Open the app, start playing a song or episode, tap the cast icon, and select your Google TV device. The audio plays through your TV's speakers. You can control playback from your phone, or use your TV remote if your Google TV device supports it.

When you're casting audio only, your TV screen may show a blank screen, album art, or a screensaver depending on the app. This is normal. Your phone can be locked or used for other tasks while the audio continues playing.

Frequently Asked Questions

Do I need to be the owner of the Google TV to cast to it?

No. Anyone on the same Wi-Fi network can cast to a Google TV device. If you want to restrict who can cast, you can turn on guest mode in your Google TV settings, which requires a PIN to cast. This prevents neighbors or visitors from casting without permission.

Can I cast from multiple phones to the same Google TV at the same time?

No. Only one device can cast at a time. If someone else tries to cast while you're already casting, their device will ask if they want to stop your casting and start theirs. You'll see a notification on your TV asking for permission.

What if my Google TV is on a different Wi-Fi band than my phone?

Some routers broadcast both 2.4 GHz and 5 GHz networks with the same name. Your phone might connect to one band while your Google TV connects to the other, and they won't see each other. Log into your router settings and either combine the bands into one network or make sure both your phone and TV connect to the same band name.

Can I cast if I'm away from home?

No. Casting requires both devices to be on the same Wi-Fi network. If you're away from home, you cannot cast to your Google TV. However, you can use remote access features in some apps — for example, YouTube TV allows you to watch on your phone and send it to a TV on your home network if you set up remote access in your account settings.

Does casting use a lot of data from my phone's plan?

No. Once casting starts, your phone is not streaming the video — your Google TV device is streaming directly from the internet. Your phone only sends a small control signal. Casting uses almost no data from your phone's plan.
