The basic steps to cast to your TV

To cast to a Chromecast device, you need three things: a Chromecast plugged into your TV's HDMI port, a device (phone, tablet, or computer) on the same Wi-Fi network, and an app or browser that supports casting. Open the app you want to cast from—YouTube, Netflix, Google Photos, or your web browser—tap or click the cast icon (it looks like a rectangle with curved lines in the corner), select your Chromecast from the list, and the content appears on your TV. Your phone or computer then acts as a remote control.

The cast icon appears in different places depending on what you're using. In YouTube, it's in the top right corner. In Netflix, it's in the top left. In Chrome on a computer, it's in the three-dot menu. Not every app has a cast button—some older apps don't support it—but most streaming services and Google's own apps do.

Key Takeaways

  • Your phone, tablet, or computer must be on the same Wi-Fi network as your Chromecast to cast successfully.
  • The cast icon appears in the app itself, not in your phone's settings—look for a rectangle with curved lines in the corner.
  • Once you tap cast and select your device, the video plays on your TV while your phone becomes the remote control.
  • Casting works with most streaming apps (YouTube, Netflix, Spotify, Google Photos) and with Chrome browser on computers.
  • If the cast icon doesn't appear, the app may not support casting, or your device may not be on the same network as your Chromecast.

Setting up your Chromecast for the first time

Before you can cast anything, your Chromecast needs to be set up and connected to your Wi-Fi. Plug the Chromecast into an HDMI port on your TV, then plug the power cable into a wall outlet or USB port. Your TV will show a setup screen with a code and instructions to read the Google Home app.

Open the Google Home app on your phone or tablet, tap the plus icon to add a device, select "Set up device," and choose "Set up a new device." The app will find your Chromecast and ask you to confirm the code on your TV screen matches the one in the app. Then select your Wi-Fi network and enter your password. The Chromecast will connect and you're ready to cast.

If your Chromecast doesn't appear in the Google Home app, make sure your phone is on the same Wi-Fi network as the Chromecast (it broadcasts its own temporary network during setup). If you're still stuck, restart both your Chromecast and your phone, then try again.

Casting from your phone or tablet

Casting from a mobile device is the most common way to use Chromecast. Open any app that supports casting—YouTube, Netflix, Hulu, Spotify, Google Photos, or others—and look for the cast icon. It's usually in the top right or top left corner of the app. Tap it, and a list of available devices appears. Select your Chromecast by name, and the content starts playing on your TV.

While content is casting, your phone screen can turn off and you can use other apps—the video keeps playing on your TV. Your phone is still controlling playback, so you can pause, skip forward or backward, adjust volume, or stop casting from the same cast menu. If you want to cast something else, just open a different app, tap cast, and select the same Chromecast.

Some apps let you cast your entire phone screen instead of just the app. In YouTube or Netflix, this isn't necessary because the cast button plays the video directly. But if you want to show photos, documents, or anything else on your TV, look for "Cast screen" or "Mirror device" in your phone's settings or the app itself.

Casting from your computer or laptop

To cast from a computer, use Google Chrome browser. Open Chrome, click the three-dot menu in the top right, and select "Cast." A panel opens showing available Chromecast devices. Click the device you want to use, and you can choose to cast either a single tab or your entire screen.

Casting a tab is useful when you want to play a video from a website or show a presentation—only that tab's audio and video go to your TV. Casting your entire screen sends everything on your monitor to the TV, which is helpful for sharing documents, spreadsheets, or anything else. Your computer stays in control the whole time, so you can click, type, and navigate normally while the TV shows what you're doing.

If you're using a Mac, the process is the same in Chrome. If you're using Firefox or Safari, those browsers don't have built-in casting, but you can still cast from apps like YouTube or Netflix if they're installed on your computer.

Troubleshooting when casting doesn't work

The most common reason casting fails is that your phone, tablet, or computer is not on the same Wi-Fi network as your Chromecast. Check your device's Wi-Fi settings and make sure it's connected to the same network name (SSID) as your Chromecast. If you're on a guest network or a different band (2.4 GHz vs. 5 GHz), your device won't see the Chromecast.

If the cast icon doesn't appear in an app, that app may not support casting. Try opening a different app like YouTube or Chrome to see if casting works there. If it does, the problem is with the first app, not your Chromecast. If the cast icon doesn't appear in any app, restart your phone and your Chromecast, then try again.

If your Chromecast appears in the cast menu but won't connect, restart both devices and make sure they're on the same network. If the video starts but keeps buffering or stopping, your Wi-Fi signal may be weak—move your Chromecast or router closer to each other, or check if other devices are using a lot of bandwidth.

Controlling playback while casting

Once content is casting to your TV, your phone or computer becomes the remote. In most apps, you can pause, play, skip forward or backward, and adjust volume from the same cast menu where you selected the device. The controls appear on your phone screen, not on your TV, so you don't need a separate remote.

If you want to stop casting, tap the cast icon again and select "Stop casting." The video stops on your TV and your phone returns to normal. If you want to cast something different, just open another app, tap cast, and select the same Chromecast—the previous content stops automatically.

Some apps let you adjust picture settings like brightness or subtitles from your phone while casting. These controls are usually in the app's settings menu, not in the cast panel itself. Check the app's menu to see what options are available.

Casting audio to speakers and soundbars

Chromecast works with more than just TVs. If you have a Chromecast Audio device (an older product no longer sold, but still used in many homes) or a speaker with Chromecast built in, you can cast music and podcasts to it the same way. Open Spotify, YouTube Music, Google Podcasts, or another audio app, tap the cast icon, select your speaker, and the audio plays through it.

Some soundbars and smart speakers also have Chromecast built in. Check your device's manual to see if it supports casting. If it does, the process is identical to casting to a TV—just tap cast and select the device.

Frequently Asked Questions

Do I need a Google account to use Chromecast?

You need a Google account to set up Chromecast in the Google Home app. Once it's set up, anyone on your Wi-Fi network can cast to it without signing in, so guests can use it too.

Can I cast from an iPhone or iPad?

Yes. Apps like YouTube, Netflix, Spotify, and Google Photos work the same way on iPhone and iPad as they do on Android. Open the app, tap the cast icon, and select your Chromecast. Some apps may have the cast button in a slightly different location, but the process is the same.

What if my Wi-Fi password has special characters?

During setup, the Google Home app lets you type your password character by character, so special characters work fine. If you're having trouble, make sure caps lock is off and you're typing it exactly as it appears in your router settings.

Can multiple people cast to the same Chromecast 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 content will replace yours. You have to stop casting first before someone else can use the device.

Does casting use a lot of data?

Casting streams video or audio over your home Wi-Fi, so it doesn't use your phone's cellular data. If you're casting from a computer, it also uses only your home Wi-Fi. Streaming quality depends on your Wi-Fi speed, not your internet plan's data limit.
