The Basic Steps to Cast to Your Chromecast

Casting to Google Chromecast means sending video, audio, or your entire screen from your phone, tablet, or computer to your TV through a small wireless connection. The process is the same whether you're casting from an Android phone, iPhone, iPad, Mac, or Windows computer: open the app or browser you want to cast from, tap or click the Cast icon (it looks like a rectangle with curved lines in the corner), select your Chromecast device from the list, and the content appears on your TV.

Your phone, tablet, or computer and your Chromecast must be on the same WiFi network for this to work. If they're on different networks, the Cast button won't find your device. Once you've cast something, you control playback from your device — you can pause, rewind, or stop without touching your TV remote.

Key Takeaways

  • Your casting device and Chromecast must be connected to the same WiFi network before you can cast anything.
  • The Cast icon appears in most video apps like YouTube, Netflix, and Disney+, and in the quick settings menu on Android phones.
  • iPhone and iPad users can cast from Safari and some apps, but the process is slightly different than on Android.
  • You control playback from your phone or computer after casting starts — the TV remote is not needed.
  • If the Cast icon doesn't appear, restart your Chromecast, restart your phone or computer, and check that both are on the same WiFi network.

Casting from Android Phones and Tablets

On Android, the Cast button lives in two places: inside individual apps like YouTube and Netflix, and in your quick settings panel. To cast from an app, open the video or music you want to watch, look for the Cast icon in the top right or bottom right corner (it looks like a rectangle with three curved lines), and tap it. A list of nearby Chromecast devices appears — select the one you want to cast to, and the content starts playing on your TV within a few seconds.

To cast your entire Android screen to your TV, swipe down twice from the top of your phone to open the full quick settings menu. Look for "Cast" or "Screen cast" and tap it. Select your Chromecast device, and everything on your phone's screen now appears on your TV. This is useful for showing photos, playing games, or sharing documents. Your phone's brightness and volume controls still work, but the TV will mirror whatever is on your screen.

Casting from iPhones and iPads

iPhones and iPads don't have a system-wide Cast button like Android does, so casting works differently depending on which app you're using. In apps that support casting — like YouTube, Netflix, Disney+, and Spotify — look for the Cast icon and tap it to send that app's content to your Chromecast. The icon location varies by app, but it's usually in the top right or bottom right corner.

To cast from Safari on an iPhone or iPad, open the webpage you want to cast, tap the Share button (the square with an arrow), scroll down and tap "AirPlay and Bluetooth," then select your Chromecast device. Not all websites support casting this way, so the option may not always appear. For screen mirroring on iOS, use AirPlay instead of Cast — swipe down from the top right corner, tap "Screen Mirroring," and select your Chromecast if it appears in the list. This works only if your Chromecast supports AirPlay, which newer models do.

Casting from Windows and Mac Computers

On Windows 10 and Windows 11, open Google Chrome and navigate to the video or content you want to cast. Click the three-dot menu in the top right corner, select "Cast," and choose your Chromecast device from the popup. The video plays on your TV while you control it from your computer. You can minimize the Chrome window or even switch to another app — casting continues in the background.

On Mac, the process is identical: open Chrome, find the content, click the three-dot menu, select "Cast," and pick your device. You can also cast your entire Mac screen by clicking the three-dot menu, selecting "Cast," then choosing "Cast desktop" instead of a specific tab. This shows everything on your screen on the TV, which is helpful for presentations or showing files to others.

Windows users can also cast from the Settings app without Chrome. Open Settings, go to System, then Display, and look for "Cast to this PC" or "Connect to a wireless display." This lets you cast from another Windows computer or Android phone directly to your PC, which then sends it to your Chromecast — though this is less common than casting directly to the device.

Troubleshooting When the Cast Icon Doesn't Appear

If you don't see the Cast icon in an app or your quick settings, the most common reason is that your phone, tablet, or computer is not on the same WiFi network as your Chromecast. Check your WiFi settings and make sure both devices are connected to the same network name. If they are, restart your Chromecast by unplugging it for 10 seconds, then plugging it back in. While it restarts, also restart your phone or computer.

If the Cast icon still doesn't appear after both devices have restarted, check that your app is up to date. Open your app store (Google Play Store, Apple App Store, or Microsoft Store) and search for the app you're trying to cast from — if an update is available, install it. Some older versions of apps don't support casting. If you're using Chrome on a computer, make sure Chrome itself is updated by clicking the three-dot menu, going to Help, and selecting "About Google Chrome."

If your Chromecast is brand new, make sure you've set it up completely using the Google Home app. The device won't appear in your Cast list until it's been added to your Google account and connected to WiFi. Open the Google Home app on your phone, tap the plus sign to add a device, and follow the on-screen steps to finish setup.

What Happens After You Start Casting

Once casting starts, your phone, tablet, or computer becomes a remote control for your TV. You can pause, play, rewind, and adjust volume from your device — you don't need the TV remote. If you're casting a video from an app like YouTube, all the playback controls appear on your phone's screen. If you're casting your screen, your device's screen stays on and mirrored to the TV, so any notifications or calls that come in will show on both screens.

You can stop casting by tapping the Cast icon again and selecting "Disconnect," or by turning off your Chromecast. If you close the app you were casting from, casting usually stops automatically. Your TV will return to whatever it was showing before you cast — usually the Chromecast home screen with the Google logo and a clock.

Casting Audio and Music to Chromecast

Casting music works the same way as casting video. Open a music app like Spotify, YouTube Music, or Apple Music, find the song or playlist you want to play, tap the Cast icon, and select your Chromecast device. The audio plays through your TV's speakers instead of your phone's speaker. You can control playback — pause, skip, adjust volume — from your phone while the music plays on the TV.

This is useful for playing background music during a gathering or party without draining your phone's battery. Your phone can go to sleep or you can use other apps while music continues playing on your TV. If you want to stop the music, tap the Cast icon again and select "Disconnect," or just pause playback from your phone.

Frequently Asked Questions

Do I need a Google account to cast to Chromecast?

You need a Google account to set up your Chromecast the first time using the Google Home app, but once it's set up, anyone on the same WiFi network can cast to it without signing in. Guests at your home can cast from their phones without knowing your password.

Can I cast from multiple devices at the same time?

No, only one device can cast to a Chromecast at a time. If someone else tries to cast while you're already casting, their content will take over and yours will stop. You can switch back by casting again from your device.

What if my WiFi is slow — will casting be choppy?

Casting works best on a strong WiFi connection. If your WiFi is slow or far from your Chromecast, video may buffer or pause. Move your Chromecast closer to your router, or move your router closer to your TV. If that's not possible, try restarting your router by unplugging it for 30 seconds.

Can I cast if my phone is on mobile data instead of WiFi?

No, your phone must be on the same WiFi network as your Chromecast. Mobile data doesn't work for casting because your phone and Chromecast need to communicate directly over WiFi.

Does casting use a lot of battery on my phone?

Casting uses some battery, but less than streaming directly to your phone. Your phone is sending a signal to your Chromecast rather than playing the video itself, so battery drain is usually minimal. You can reduce battery use by lowering your phone's screen brightness or letting the screen turn off while casting.
