The Basic Steps to Cast to Your TV

Chromecast works by sending video, audio, or your entire screen from your phone, tablet, or computer to a TV that has a Chromecast device plugged in. The device itself is small—about the size of a thumb drive—and connects to your TV's HDMI port and power. Once it's plugged in and connected to your home Wi-Fi network, you can cast from any compatible device on the same network.

The casting process itself takes seconds: you open an app that supports Chromecast (like YouTube, Netflix, or Google Photos), tap the cast icon, select your Chromecast device, and the content appears on your TV. Your phone or computer becomes a remote control, so you can pause, rewind, or adjust volume without pointing anything at the screen.

Key Takeaways

  • Your Chromecast device must be plugged into your TV's HDMI port and connected to the same Wi-Fi network as your phone or computer.
  • You cast from apps that have the cast icon built in—YouTube, Netflix, Spotify, Google Photos, and many others support it natively.
  • Casting pauses or stops if you disconnect from Wi-Fi or move out of range, but your TV will show a "disconnected" message rather than going blank.
  • You can cast your entire screen from Android phones and Windows computers, but screen mirroring from iPhones and Macs requires an Apple TV or third-party workaround.
  • The first time you set up Chromecast, you'll need the Google Home app to connect it to your Wi-Fi and name it.

Setting Up Your Chromecast Device for the First Time

Plug the Chromecast into an available HDMI port on your TV and connect the power cable to a nearby outlet or USB port. Turn on your TV and switch to the HDMI input where you plugged in the Chromecast. You should see a setup screen appear on your TV with a code and instructions to read the Google Home app.

On your phone or tablet, read the Google Home app (free from the Google Play Store or Apple App Store). Open it, tap the plus icon to add a device, and 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 the code shown on your TV screen. Once confirmed, you'll select your home Wi-Fi network and enter the password. The Chromecast will connect and restart—this takes about a minute.

After setup completes, give your Chromecast a name (like "Living Room TV" or "Bedroom") so you can identify it when casting from multiple devices. You can change this name anytime in the Google Home app by tapping the device, then the settings gear icon.

Casting from Your Phone or Tablet

Open any app that supports Chromecast—YouTube, Netflix, Spotify, Google Photos, and Hulu are common examples. Look for the cast icon, which looks like a rectangle with curved lines in the bottom-left corner. Tap it and a list of available Chromecast devices will appear. Select the one you want to cast to.

Once you've selected a device, the content starts playing on your TV when ready. Your phone or tablet screen will show a mini player with pause, play, and volume controls. You can lock your phone, switch to another app, or even turn off the screen—the cast will continue. To stop casting, tap the cast icon again and select "Disconnect."

If the cast icon doesn't appear in an app, that app doesn't support Chromecast natively. In that case, you can cast your entire screen instead (see the section below on screen mirroring), though this uses more battery and may be slower.

Casting Your Entire Screen from Android or Windows

If you want to cast something that isn't in a Chromecast-compatible app—like a web browser, a document, or a game—you can mirror your entire screen. On Android phones and tablets, swipe down from the top of the screen twice to open the quick settings panel. Look for "Cast" or "Screen cast" and tap it. Select your Chromecast device from the list. Your entire screen will now appear on your TV, and you can control it normally from your device.

On Windows computers, right-click the Windows icon in the bottom-left corner and select "System." Scroll down and click "Projecting to this PC" on the left side. Then open the Action Center (Windows key + A) and click "Connect." Select your Chromecast device. Your screen will mirror to the TV. To stop, open the Action Center again and click "Disconnect."

Screen mirroring drains your phone or computer battery faster than casting from an app, and it may lag slightly if your Wi-Fi signal is weak. For this reason, casting from individual apps is usually the better choice when available.

What to Do If Your Chromecast Won't Connect

The most common reason casting fails is that your phone and Chromecast are on different Wi-Fi networks. Check that both devices are connected to the same network—you can see this in your phone's Wi-Fi settings and in the Google Home app under your Chromecast's device details. If you've recently changed your Wi-Fi password, you'll need to reconnect the Chromecast to the network. Open Google Home, tap your Chromecast device, tap the settings gear, and select "Wi-Fi" to re-enter the password.

If your Chromecast isn't appearing in the cast menu at all, restart both devices. Unplug the Chromecast for 10 seconds, plug it back in, and wait for it to fully boot (the light will stop blinking). Then restart your phone or computer. If the problem persists, move your phone closer to the Chromecast and router to rule out a weak signal.

If you see the cast icon but get an error when you try to connect, check that your Wi-Fi network is stable by opening a web browser and loading a website. If the internet is working, try restarting the app you're casting from. If that doesn't work, restart your Chromecast again.

Casting from iPhones and Mac Computers

iPhones and Macs don't have native Chromecast support built into the operating system. However, many apps—including YouTube, Netflix, and Spotify—have Chromecast built in, so you can cast from those apps just as you would on Android or Windows. Look for the cast icon and tap it to select your Chromecast device.

If you want to mirror your entire iPhone or Mac screen to a TV with Chromecast, you'll need to use a workaround. Some third-party apps in the App Store claim to enable screen mirroring, but they vary in reliability. A more straightforward option is to use an Apple TV instead of Chromecast if you're in an Apple ecosystem, since AirPlay (Apple's casting system) is built into iPhones and Macs. Alternatively, you can cast to Chromecast from a web browser on your Mac by opening Chrome, clicking the three-dot menu, selecting "Cast," and choosing your Chromecast device.

Controlling Playback and Adjusting Settings

When you're casting from an app, your phone or tablet becomes the remote. The mini player shows pause, play, rewind, and fast-forward buttons. You can also adjust volume from your device or from your TV's physical remote—both work simultaneously. If you're casting music, you can skip to the next track or previous track from the mini player.

To change which Chromecast device you're casting to mid-stream, tap the cast icon again and select a different device. The content will switch to the new TV without stopping. You can also adjust Chromecast settings in the Google Home app: tap the device, then the settings gear to change the name, restart the device, or manage Wi-Fi settings.

If you want to stop casting but keep the app open on your phone, tap the cast icon and select "Disconnect." The content will stop playing on the TV, but your app will remain open and ready to cast again.

Frequently Asked Questions

Can multiple people cast to the same Chromecast 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, they'll see a prompt asking if they want to take over. If they confirm, your cast will stop and theirs will start. You can prevent this by locking casting to your device in the Google Home app settings.

Do I need to pay for Chromecast or is there a subscription?

Chromecast itself is a one-time purchase (usually $30 to $40 depending on the model). There's no subscription fee to use it. However, the apps and services you cast from—like Netflix, Spotify, or YouTube Premium—may require their own subscriptions.

What happens if I lose Wi-Fi while I'm casting?

The cast will pause or stop, and your TV will show a "disconnected" message. Once your Wi-Fi reconnects, you can resume casting from where you left off in most apps. If you're casting a live stream, you may have to start over.

Can I cast to Chromecast from outside my home?

No. Casting requires your phone and Chromecast to be on the same Wi-Fi network. You can't cast from a coffee shop to a Chromecast at home. However, some apps like YouTube allow you to remotely control a Chromecast if you're signed into the same Google account, which is different from casting.

Why is my cast lagging or freezing?

Lag usually means your Wi-Fi signal is weak or your network is congested. Move your phone closer to the router, or restart your router by unplugging it for 10 seconds. If other devices are using a lot of bandwidth (like someone streaming video on another device), that can also slow down casting. Switching to the 5 GHz Wi-Fi band instead of 2.4 GHz can help if your router supports it.
