The basic steps to cast to Chromecast

Streaming to Chromecast means sending video, music, or photos from your phone, tablet, or computer to your TV through the Chromecast device. The process differs slightly depending on what you're streaming and what device you're using, but the core idea is the same: you open an app that supports casting, tap the cast button, pick your Chromecast, and the content plays on your TV instead of your phone.

Before you start, make sure your Chromecast is plugged into your TV, powered on, and connected to the same Wi-Fi network as your phone or computer. Your Chromecast should appear in the Wi-Fi list during setup — if you haven't set it up yet, use the Google Home app to complete that first.

Once everything is connected, the actual casting takes seconds. The cast button typically looks like a rectangle with curved lines in the corner, though the exact appearance varies by app. When you tap it, a list of available devices appears — select your Chromecast by name, and the content moves to your TV.

Key Takeaways

  • Your phone, tablet, or computer and your Chromecast must be on the same Wi-Fi network for casting to work.
  • The cast button appears in most video and music apps — YouTube, Netflix, Spotify, Google Photos, and many others — but not all apps support it.
  • Once you tap cast and select your device, you can close the app or lock your phone and the content keeps playing on your TV.
  • If the cast button doesn't appear, the app may not support Chromecast, or your devices may not be on the same network.

Casting from Android phones and tablets

Android devices have the strongest Chromecast support because Google makes both. Open any app that supports casting — YouTube, Netflix, Spotify, Google Photos, Google Play Music, Hulu, Disney+, and dozens of others — and look for the cast icon in the top right or bottom right corner of the screen.

Tap the cast icon and a list of nearby Chromecast devices appears. Select the one you want to use by name. The app will ask you to confirm, and within a second or two, the video or music starts playing on your TV. Your phone screen returns to normal, and you can lock it, switch apps, or set it down — the content continues on your TV.

If you don't see the cast icon, swipe down from the top of your screen to open Quick Settings, look for a "Cast" or "Screen cast" option, and tap it. This method casts your entire phone screen rather than just the app, which is slower but works with any app.

Casting from iPhones and iPads

Apple devices don't have built-in Chromecast support the way Android does, but most major streaming apps include a cast button anyway. Open Netflix, YouTube, Spotify, Hulu, Disney+, or another app that supports Chromecast, and tap the cast icon — usually in the top right corner.

Select your Chromecast from the list, and the content plays on your TV. The process is identical to Android, even though the underlying technology is different. Not every app supports Chromecast on iOS, so if you don't see a cast button, that app may not offer it.

If you need to cast an app that doesn't have a cast button, you can use AirPlay to send your screen to an Apple TV instead, but that won't work with Chromecast. For Chromecast specifically, you're limited to apps that include the feature.

Casting from Windows and Mac computers

Casting from a computer works differently than from a phone. Google Chrome browser has built-in casting — open Chrome, click the three-dot menu in the top right, select "Cast", and choose your Chromecast device. You can then cast a single tab or your entire screen.

Casting a tab is faster and uses less bandwidth. Casting your entire screen is useful if you want to show something that isn't in a browser, like a document or a presentation. Both options let you continue using your computer while the content plays on your TV.

Some apps like Netflix, YouTube, and Spotify also have their own cast buttons on the desktop versions. Look for the cast icon in the app itself before opening Chrome — it's usually faster and more reliable than casting through the browser.

Troubleshooting when casting doesn't work

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 name. If you have a 5GHz and 2.4GHz network with the same name, try connecting your phone to the same band your Chromecast is using — Chromecast typically connects to 2.4GHz.

If the cast button doesn't appear in an app, that app may not support Chromecast. Try a different app to confirm your Chromecast is working. If casting works in some apps but not others, the problem is with that specific app, not your setup.

If your Chromecast isn't showing up in the device list at all, restart both your Chromecast and your phone. Unplug the Chromecast for 10 seconds, plug it back in, wait for the light to stop blinking, and try again. If it still doesn't appear, open the Google Home app and check that your Chromecast is online and connected to the correct network.

What happens after you start casting

Once content is playing on your TV, your phone becomes a remote control. You can pause, play, skip forward or backward, and adjust volume — all from your phone screen. The app shows you what's currently playing and how much time is left.

You can lock your phone, switch to another app, or set it down, and the content keeps playing. If you need to stop casting, tap the cast icon again and select "Stop casting", or straightforward turn off your TV. The content stops when ready.

If you want to switch to a different Chromecast device, tap the cast icon, select a different device, and the content moves to that TV. You can only cast to one device at a time from a single app.

Casting photos and music instead of video

Casting music works the same way as video. Open Spotify, YouTube Music, Google Play Music, or another music app, tap the cast icon, select your Chromecast, and the music plays through your TV speakers. Your phone screen can lock or show the album art — you control it.

For photos, open Google Photos, tap the cast icon, and select your Chromecast. Your photos display on your TV as a slideshow. You can swipe through them on your phone to control what appears on the screen, or let them cycle automatically.

Some apps like Spotify show the album art or a visualizer on your TV while music plays, which is useful for parties or background music. Others show a blank screen with sound only. Check what your app displays before you start casting.

Frequently Asked Questions

Do I need to be connected to the internet for Chromecast to work?

Yes. Both your phone and your Chromecast need to be on the same Wi-Fi network. If your Wi-Fi goes down, casting stops. You cannot cast over Bluetooth or a direct connection without Wi-Fi.

Can I cast to multiple Chromecast devices at the same time?

No. One app can only cast to one Chromecast at a time. If you want to play the same content on multiple TVs, you would need to start casting on each TV separately using different phones or computers.

What if the cast button is grayed out or won't respond?

This usually means your phone and Chromecast aren't on the same network, or the app doesn't support casting. Check your Wi-Fi connection first. If both devices are on the same network and the button still won't work, close the app completely and reopen it.

Can I cast while using a VPN?

It depends on the VPN. Some VPNs block local network traffic, which prevents casting. Try turning off your VPN temporarily to see if casting works. If it does, your VPN is the problem — you may need to adjust its settings or use a different VPN.

Does casting drain my phone battery faster?

Casting uses Wi-Fi continuously, so your battery drains faster than normal, but not dramatically. If you're casting for hours, plug your phone in. For typical use — casting a movie or music for an hour or two — the battery impact is minor.
