What casting means and why you'd do it

Casting means sending video, audio, or your phone's entire screen to your PC wirelessly. Your phone stays in your hand—you're just mirroring what it shows onto a larger display. You might cast to watch a video from your phone on a bigger screen, share photos with someone sitting next to you, or use your PC monitor to see what you're doing on your phone while you work.

The method you use depends on what phone and PC you have, and what you're trying to cast. Some routes work across any phone and PC. Others only work if both devices are made by the same company. Some are built into Windows or Android. Others need a free app you read first.

Key Takeaways

  • Windows 10 and 11 have a built-in casting receiver called Connect, which works with Android phones and some other devices without needing extra software.
  • Android phones can cast to Windows through the Your Phone app (if you have Windows 11) or by using third-party apps like Miracast or Google Home.
  • iPhones cannot mirror their screen to Windows natively, but you can cast audio or video content through apps like AirBeamTV or by using a web browser.
  • Both your phone and PC must be on the same Wi-Fi network for wireless casting to work, and some methods require you to enable casting in your phone's settings first.
  • If casting fails, restart both devices, move closer to your router, and check that casting is turned on in your phone's developer settings or quick menu.

Casting from Android to Windows using built-in tools

Windows 10 and 11 both have a Connect app (also called Wireless Display) that lets Android phones send their screen to your PC. This is the simplest route if you have an Android phone, because no extra software is needed on either device.

On your PC, open the Start menu and search for "Connect". Click the app to open it. The app will show a waiting screen. On your Android phone, swipe down from the top of the screen twice to open Quick Settings, then look for "Cast", "Screen Cast", or "Wireless Display". Tap it, wait a moment for your PC to appear in the list, and tap your PC's name. Your phone's screen should appear on your monitor within a few seconds.

If your phone doesn't show a Cast option in Quick Settings, go to Settings > Display > Cast (or Advanced > Cast) and turn it on. Some Android phones bury this in Developer Options instead—if you can't find it in Display, go to Settings > About Phone, tap Build Number seven times, then go back to Settings and open Developer Options. Look for "Wireless Display Debugging" or "Enable Wireless Display" and turn it on.

Casting from Android using the Your Phone app (Windows 11 only)

Windows 11 includes the Your Phone app, which connects your Android phone more deeply to your PC than straightforward screen casting. It lets you see your phone's screen, open apps, and even drag files between devices. This method requires you to sign in with a Microsoft account on both your phone and PC.

On your PC, open the Start menu and search for "Your Phone". Click the app and sign in with your Microsoft account. On your Android phone, read the "Link to Windows" app from the Google Play Store (it's made by Microsoft). Open it, sign in with the same Microsoft account, and follow the prompts to link your phone to your PC. Once linked, open Your Phone on your PC again—your phone's screen should now appear in a window on your monitor.

This method is more reliable than the Connect app for newer Android phones, and it gives you more control. You can also use it to send text messages, view notifications, and access your phone's photos directly from your PC.

Casting from iPhone to Windows

iPhones cannot mirror their screen to Windows natively—Apple's AirPlay system only works with other Apple devices. However, you have two workarounds: use a third-party app, or cast audio and video content through a web browser.

For full screen mirroring, read AirBeamTV (paid app, around $5) or Reflector (also paid) on both your iPhone and PC. These apps create a private connection between your devices and let you mirror your iPhone's screen to Windows. Follow the app's setup instructions to connect them on the same Wi-Fi network.

If you only want to cast video or audio—not your entire screen—you can use a web browser instead. Open a web browser on your PC, go to YouTube or another streaming site, and play a video. On your iPhone, swipe up from the bottom (or down from the top right on newer models) to open Control Center, tap AirPlay, and select your PC if it appears. This works only if your PC is running AirPlay-compatible software, which most Windows PCs are not. For most iPhone users, a third-party app is the more reliable choice.

Making sure both devices are ready to cast

Before you try casting, check that your phone and PC are both on the same Wi-Fi network. Open your phone's Wi-Fi settings and your PC's network settings and confirm they're connected to the same network name (SSID). If they're on different networks, casting won't work.

On your phone, make sure casting is turned on. For Android, this usually means going to Settings > Display or Settings > Connected Devices and looking for Cast, Screen Cast, or Wireless Display. Turn it on if it's off. For iPhone, casting is always on, but AirPlay only works if you're using a compatible app or if your PC has AirPlay receiver software installed.

On your PC, make sure your Wi-Fi is on and you're connected to the same network. If you're using the Connect app on Windows, it should start listening for incoming casts as soon as you open it. If you're using Your Phone on Windows 11, make sure you've signed in with your Microsoft account and that your Android phone is linked.

Troubleshooting when casting doesn't work

If your phone doesn't see your PC in the cast list, restart both devices and try again. Turn off your phone's Wi-Fi, wait five seconds, and turn it back on. Do the same on your PC. Move both devices closer to your Wi-Fi router—casting uses a lot of bandwidth and works better when the signal is strong.

If your PC appears in the cast list but the connection fails, check that casting is actually enabled on your PC. On Windows, open the Connect app again and make sure it's running. If you're using Your Phone, sign out and sign back in with your Microsoft account. If the problem persists, restart your Wi-Fi router by unplugging it for 30 seconds, plugging it back in, and waiting for it to reconnect.

For Android phones, if Cast doesn't appear in Quick Settings, it may be hidden. Go to Settings > Display > Advanced > Cast and turn it on. If it's still not there, your phone may not support wireless casting—check your phone's manual or manufacturer's website. For iPhones, if AirPlay isn't working, make sure your PC has AirPlay receiver software (like Reflector or AirBeamTV) installed and running.

What to expect once you're casting

Once casting starts, your phone's screen will appear on your PC monitor in real time. There's usually a small delay of a quarter-second to a second, depending on your Wi-Fi speed. You can still use your phone normally—touch the screen, open apps, and everything will show up on your PC. Your phone's battery will drain faster while casting because it's sending data constantly, so plug it in if you plan to cast for more than an hour.

The quality of the cast depends on your Wi-Fi connection and your phone's screen resolution. If your Wi-Fi is slow or crowded, the image may lag or drop frames. Moving closer to your router or switching to a less crowded Wi-Fi channel can help. If you're casting video or games, a wired connection on your PC (using Ethernet instead of Wi-Fi) can improve performance.

Frequently Asked Questions

Do I need to install anything on my PC to cast from my Android phone?

No. Windows 10 and 11 have the Connect app built in, so you don't need to read anything. Just open Connect and your phone should find it. If you want to use Your Phone on Windows 11, you'll need to read the "Link to Windows" app on your Android phone, but nothing extra goes on your PC.

Can I cast from my iPhone to a Windows PC?

Not directly. iPhones only support AirPlay, which works with Apple devices. To cast an iPhone to Windows, you need a third-party app like AirBeamTV or Reflector, which you buy and install on both devices. Alternatively, you can cast video or audio through a web browser if your PC has AirPlay receiver software.

What if my phone and PC are on different Wi-Fi networks?

Casting won't work. Both devices must be on the same Wi-Fi network to communicate. Connect your phone to the same network your PC is on, then try casting again. If you're on a guest network, make sure both devices are on the same guest network, not one on guest and one on the main network.

Does casting use a lot of data or battery?

Casting uses Wi-Fi bandwidth but not cellular data, so it won't count against a mobile data plan. It does drain your phone's battery faster because the phone is constantly sending video to your PC. Plug your phone in if you plan to cast for more than an hour.

Can I cast just audio without showing my entire screen?

Yes. Most phones can cast audio to Bluetooth speakers or to a PC running media player software. On Android, open a music or podcast app, look for a Cast icon (usually a rectangle with a Wi-Fi symbol), and select your PC. On iPhone, use AirPlay the same way if your PC has AirPlay receiver software installed.
