How to set up Chromecast for the first time

Chromecast works by connecting a small device to your TV's HDMI port, then letting your phone, tablet, or computer send video and audio to it wirelessly. To set it up, plug the Chromecast device into an available HDMI port on your TV, then plug its power cable into a nearby outlet or USB port. Turn on your TV and switch to the HDMI input where you plugged in the Chromecast.

On your phone or tablet, read the Google Home app from the App Store (Apple) or Google Play (Android). Open the app and tap the plus icon in the top left corner, then select "Set up device." Choose "Set up a new device" and follow the prompts. The app will search for your Chromecast and ask you to confirm a code that appears on both your TV screen and your phone — this confirms they're connecting to each other. Select your home Wi-Fi network and enter your password when prompted.

Once connected, your Chromecast will display a screensaver on your TV. You can customize the background and other settings in the Google Home app by tapping on your Chromecast device and selecting "Settings." The whole process usually takes five to ten minutes.

Key Takeaways

  • Chromecast plugs into your TV's HDMI port and needs power from an outlet or USB port to work.
  • You set it up using the Google Home app on your phone or tablet by confirming a code that appears on both screens.
  • Once connected to your Wi-Fi, you can send video from apps like YouTube, Netflix, and Disney+ directly to your TV.
  • Casting from your phone means the video plays on the TV while your phone acts as a remote control.
  • You can cast from a computer's Chrome browser by clicking the cast icon in the top right corner of the address bar.

Casting video from your phone or tablet

To send video from your phone to your TV, open an app that supports Chromecast — Netflix, YouTube, Disney+, Hulu, and most other streaming services have the feature built in. Look for the cast icon, which looks like a rectangle with curved lines in the bottom left corner. Tap it and select your Chromecast device from the list.

The video will start playing on your TV while your phone shows playback controls. You can pause, rewind, or adjust the volume from your phone, and the TV remote will also work. Your phone's screen can go dark or you can use other apps — the video keeps playing on the TV independently. To stop casting, tap the cast icon again and select "Stop casting."

If you don't see the cast icon in an app, that app doesn't support Chromecast directly. In that case, you can cast your entire phone screen instead by opening the Google Home app, tapping your Chromecast device, and selecting "Cast my screen." This mirrors everything on your phone to the TV, though it uses more battery and may have a slight delay.

Casting from a computer or laptop

To cast from a computer, you need to be using Google Chrome as your browser. Open Chrome and look for the cast icon in the top right corner of the address bar — it looks like a rectangle with curved lines. Click it and select your Chromecast device.

You have two options: "Cast tab" sends only the current browser tab to your TV, while "Cast entire screen" mirrors your whole desktop. Casting a tab is useful for watching YouTube or viewing a website on a bigger screen. Casting your entire screen is helpful if you want to show a presentation or share something that isn't in a browser window.

If you don't see the cast icon, click the three-dot menu in the top right corner of Chrome, hover over "Cast," and select your device from there. To stop casting, click the cast icon again and select "Stop casting."

Troubleshooting when Chromecast won't connect

If your Chromecast isn't appearing in the cast menu, first check that your phone, tablet, or computer is on the same Wi-Fi network as the Chromecast. The Chromecast device and your casting device must be connected to the same network to find each other. Look at your Wi-Fi settings and confirm both are using the same network name.

If they're on the same network and still not connecting, restart your Chromecast by unplugging it for 30 seconds, then plugging it back in. While it's restarting, also restart your phone or computer. Once both have powered back on, try casting again.

If the cast icon doesn't appear in an app, that app may not support Chromecast. Check the app's settings or help section to confirm. Some older apps or regional versions don't have casting built in. If an app should have the feature but doesn't, try updating it to the latest version from your app store.

If video starts playing but then stops or buffers constantly, your Wi-Fi signal may be weak. Move your Chromecast closer to your router, or move your router closer to your TV. Walls and distance weaken Wi-Fi signals, so reducing the distance between devices often solves buffering problems.

Controlling playback and adjusting settings

Once video is casting to your TV, your phone or tablet becomes a remote control. You can pause, play, rewind, and skip forward using the controls on your screen. You can also adjust the volume using your phone's volume buttons or the on-screen controls. If you're casting from a computer, the same controls appear in your browser.

Your TV remote will also work for volume and input selection, but it won't control playback of the cast video — use your phone or computer for that. If you want to use only your TV remote, you can use a Chromecast-compatible remote like the Google TV remote, which gives you full control without needing your phone.

To change Chromecast settings like the screensaver background or device name, open the Google Home app, tap your Chromecast device, and select "Settings." From there you can rename the device, change the background image, adjust display settings, or remove the device from your home.

Using Chromecast with multiple people in your home

Multiple people can cast to the same Chromecast device as long as they're on the same Wi-Fi network. Each person uses their own phone or computer to send video — only one video plays at a time, so whoever casts last will interrupt what was playing before.

If you want to prevent others from casting to your Chromecast, you can set a PIN in the Google Home app. Open the app, tap your Chromecast device, select "Settings," and turn on "Guest mode." This lets you choose whether guests can cast without a PIN or need to enter one. When guest mode is on, people casting for the first time will see a PIN on the TV screen that they must enter on their device.

You can also create separate home profiles in the Google Home app if you have multiple people in your household. Each person can have their own profile, and you can control which devices and services each profile can access. This is useful if you want to restrict what children can cast or keep personal streaming accounts separate.

Casting music and audio to speakers

Chromecast works with audio-only devices too, like Google Home speakers and other Chromecast-enabled speakers. To cast music, open a music app like Spotify, YouTube Music, or Apple Music, look for the cast icon, and select a speaker instead of your TV. The music will play through that speaker while your phone controls playback.

You can cast music to multiple speakers at once by selecting them all before you start playing. This is useful for playing the same song throughout your home. Some apps let you group speakers together so they stay synced — check your app's settings to see if this feature is available.

Audio casting uses the same Wi-Fi connection as video casting, so make sure your speaker is on the same network as your phone or computer. If a speaker isn't appearing in the cast menu, restart it and your casting device, then try again.

Frequently Asked Questions

Do I need a Google account to use Chromecast?

You need a Google account to set up Chromecast using the Google Home app. However, once it's set up, other people on your Wi-Fi network can cast to it without signing in. If you want to use guest mode or create household profiles, you'll manage those through your own Google account.

Can I cast if I'm not home?

No, Chromecast only works when your phone or computer is on the same Wi-Fi network as the device. You cannot cast from outside your home over the internet. Some newer Google TV devices have remote casting features, but standard Chromecast requires a local Wi-Fi connection.

What if my TV doesn't have an HDMI port?

Most TVs made in the last 10 years have at least one HDMI port. If your TV is older and doesn't have HDMI, you cannot use Chromecast. You would need to replace the TV or use a different streaming device that works with your TV's available ports.

Does casting drain my phone's battery?

Casting uses Wi-Fi and keeps your phone's screen active, so it does drain battery faster than normal. Casting a single tab from Chrome uses less battery than casting your entire screen. If you're casting for a long time, plug your phone into a charger to avoid running out of power.

Can I use Chromecast without Wi-Fi?

No, Chromecast requires a Wi-Fi connection to work. It connects wirelessly to your phone or computer, and both devices must be on the same network. If you don't have Wi-Fi, Chromecast won't function.
