How to Cast Google to Your TV Using Chromecast

The Basic Steps to Cast to Your TV

To cast Google content to your TV, open the app or website you want to watch on your phone, tablet, or computer, then tap or click the Cast button (it looks like a rectangle with curved lines in the corner). Select your Chromecast device from the list, and the content will start playing on your TV within seconds. Your phone or computer stays in your hand as a remote—you can pause, skip, or adjust volume without touching the TV.

The Cast button appears in most Google apps including YouTube, Google Photos, Google Play Music, and Chrome browser. If you don't see it, make sure your phone or computer is on the same Wi-Fi network as your Chromecast device. The button won't show up if the devices can't find each other on the network.

Key Takeaways

The Cast button appears in most Google apps and the Chrome browser when your phone or computer is on the same Wi-Fi as your Chromecast.
You can cast from your phone, tablet, or computer—just tap or click the Cast button and pick your TV from the list.
Your device controls playback after casting starts; you don't need to keep the app open on your phone, but closing it will stop the cast.
If the Cast button doesn't appear, restart your Chromecast device and make sure both devices are connected to the same Wi-Fi network.
Casting uses your Wi-Fi connection, not your phone's data, so you can cast while on a home network without using mobile data.

Setting Up Your Chromecast Device First

Before you can cast anything, your Chromecast must be plugged into your TV's HDMI port and powered on. The device needs to be connected to the same Wi-Fi network as your phone or computer. During setup, the Chromecast displays a code on your TV screen and asks you to enter it in the Google Home app on your phone—this pairs the device to your Wi-Fi.

If you're setting up for the first time, open the Google Home app, tap the plus icon to add a device, select "Set up device," and follow the on-screen prompts. The app will ask you to confirm your Wi-Fi network and create a name for your Chromecast (like "Living Room TV" or "Bedroom"). Once setup is complete, your Chromecast stays connected to that Wi-Fi and is ready to receive casts from any device on the same network.

Check that your Chromecast is on the same Wi-Fi band as your phone. Some routers broadcast both 2.4 GHz and 5 GHz networks with the same name. If your phone is on 5 GHz and your Chromecast is on 2.4 GHz, they won't see each other. You can usually fix this by going into your router settings or asking your Chromecast to connect to the other band during setup.

Casting from YouTube, Photos, and Other Google Apps

YouTube is the easiest app to practice casting with. Open any video, and the Cast button appears in the top right corner of the screen. Tap it, select your TV, and the video plays on your TV while you control it from your phone. You can pause, rewind, skip ahead, or adjust volume—all from your phone. The video keeps playing even if you switch to another app on your phone, though closing YouTube entirely will stop the cast.

Google Photos works the same way. Open a photo or album, tap the Cast button, choose your TV, and the images display on the big screen. This is useful for showing family photos or slideshows without connecting cables. Google Play Music, Podcasts, and other Google services all follow the same pattern: find the Cast button, tap it, pick your device, and enjoy.

If the Cast button is grayed out or missing, the app may not support casting, or your device isn't on the same network. Try restarting both your phone and Chromecast. Unplug the Chromecast for 10 seconds, plug it back in, and wait for it to fully boot up (usually about 30 seconds). Then open the app again and look for the Cast button.

Casting from Your Web Browser Using Chrome

You can cast almost anything from your computer using the Chrome browser. Open Chrome, click the three-dot menu in the top right, and select "Cast." A small window appears showing available Chromecast devices. Click the one you want, and your browser tab starts playing on your TV. You can keep using your computer while the cast is active—the video continues on your TV even if you switch tabs or minimize Chrome.

This method works for websites that don't have their own Cast button, like streaming services that haven't built in native casting, or for sharing presentations, recipes, or anything else on your screen. You can cast the entire tab or just the audio, depending on what you're watching. The quality depends on your Wi-Fi speed, so if you're casting video, a strong signal gives better results.

To stop casting from Chrome, click the Cast button again and select "Stop casting." The video will stop playing on your TV, and you can close the Cast window. If your computer goes to sleep, the cast will pause until you wake it up.

Troubleshooting When Cast Doesn't Work

The most common reason casting fails is that your phone or computer isn't on the same Wi-Fi network as your Chromecast. Check your phone's Wi-Fi settings and confirm you're connected to the same network name (SSID) as your Chromecast. If you're on a guest network or a different band, switch to the main network and try again.

If your Chromecast isn't showing up in the Cast menu at all, restart it by unplugging the power cable for 10 seconds, then plugging it back in. Wait about 30 seconds for it to fully restart. While it's restarting, also restart your phone or computer. Once both devices are back on, open your app and look for the Cast button again.

If casting starts but stops after a few seconds, your Wi-Fi connection may be weak or unstable. Move closer to your router, or check if other devices are using a lot of bandwidth. Streaming video uses significant data, so if someone else is downloading large files or video calling, it can interrupt your cast. Pause those activities and try again.

For persistent problems, forget the Wi-Fi network on your Chromecast and reconnect it. In the Google Home app, select your Chromecast device, tap the settings icon, go to "Wi-Fi," and select "Forget." Then reconnect to your Wi-Fi network by following the setup process again. This often fixes connection issues that restart alone won't solve.

What Happens to Your Phone While Casting

Once you start casting, your phone or computer acts as a remote control, but it doesn't have to stay in the app. You can switch to another app, check email, or browse the web while your video plays on the TV. The cast continues uninterrupted. Your device sends the command to play to your Chromecast, and then the Chromecast streams the content directly from the internet—your phone isn't relaying the video.

However, if you close the app entirely (not just switch away from it), the cast will stop. For example, if you're casting YouTube and you swipe YouTube away from your recent apps, the video stops. To keep casting, leave the app running in the background, even if you're not looking at it. You can lock your phone's screen and the cast will continue.

Your phone's battery drains more slowly when casting than when actively streaming to the phone itself, since the screen isn't displaying the video. This makes casting useful for longer viewing sessions when you want to save battery.

Casting to Multiple TVs and Switching Devices

If you have more than one Chromecast in your home, each one appears in the Cast menu with the name you gave it during setup. Tap the name of the TV you want to cast to, and the content moves to that device. You can switch between TVs by opening the Cast menu again and selecting a different device. The previous TV stops playing, and the new one starts.

You can't cast to two TVs at the same time from a single phone or computer—only one Chromecast device can receive a cast from your device at a time. However, different people can cast to different TVs simultaneously. If your partner is casting to the living room TV from their phone, you can cast to the bedroom TV from yours at the same time.

Frequently Asked Questions

Do I need to keep my phone unlocked while casting?

No. Once the cast starts, you can lock your phone's screen and put it in your pocket. The video continues playing on your TV. Your phone is just sending control commands, not streaming the video itself, so the screen doesn't need to stay on.

Can I cast if I'm not home on the same Wi-Fi?

No. Casting requires your phone or computer and your Chromecast to be on the same Wi-Fi network. If you're away from home, you can't cast to a Chromecast on your home network. Some newer Chromecast models support remote casting through your Google account, but this isn't available on all devices.

What if the video keeps stopping or buffering while I cast?

This usually means your Wi-Fi signal is weak or your network is congested. Move closer to your router, or ask others to pause downloads and video calls. If the problem continues, restart your Chromecast by unplugging it for 10 seconds. You can also check your router's distance from your TV—walls and distance weaken the signal.

Can I cast from an iPhone or iPad?

Yes. The Cast button works the same way on iPhones and iPads as it does on Android phones. Open a Google app like YouTube or Google Photos, tap the Cast button, and select your TV. You need to be on the same Wi-Fi network as your Chromecast.

Why doesn't the Cast button show up in some apps?

Not all apps support casting. Older apps or apps from companies that haven't built in Cast support won't show the button. You can still cast from those apps using Chrome on your computer by casting the entire browser tab, but you won't see a Cast button in the app itself on your phone.
