The three ways to mirror or cast your phone to a computer

You can display your phone screen on your PC using three main methods: wireless casting (which works over your home network), a USB cable connection (which is more stable but requires a physical link), or third-party software that mirrors your phone without needing the phone and PC to be on the same network. Which one works best depends on whether you need portability, reliability, or the ability to control your phone from the PC itself.

Windows PCs and Android phones have built-in casting features that work without extra software. iPhones require either a cable, AirPlay (if your PC has AirPlay support), or third-party apps. The method you choose also affects whether you can interact with your phone's screen or just view it.

Key Takeaways

  • Windows PCs can receive Android phone screens wirelessly through the built-in Cast feature, which both devices must be on the same Wi-Fi network to use.
  • A USB cable connection works with Android phones and iPhones and does not require Wi-Fi, making it the most reliable option for presentations or screen sharing.
  • Third-party apps like Scrcpy (free, open-source) and AnyDesk let you mirror and control your phone from your PC without needing both devices on the same network.
  • iPhones do not have native casting to Windows PCs; you will need either a cable, an app like Reflector, or a Mac with AirPlay support.
  • Casting uses more battery on your phone than a wired connection, so use a cable if you plan to display your screen for more than an hour.

Wireless casting with Windows and Android

The simplest wireless method is to use the built-in Cast feature on Windows 10 and 11. Both your phone and PC must be connected to the same Wi-Fi network. On your Android phone, open Settings, go to Connected devices or Display, and look for Cast, Screen Cast, or Wireless Display. The exact name varies by phone manufacturer.

On your Windows PC, open the Settings app, go to System, then Display, and scroll down to find "Cast to a device" or "Connect to a wireless display." Click it and your PC will search for nearby phones and tablets. When your phone appears in the list, tap it to begin mirroring. Your phone screen will now appear on your PC monitor, and you can interact with your phone normally—the PC is just displaying what your phone shows.

This method works well for presentations, showing photos, or demonstrating an app to someone else. The connection is stable as long as both devices stay on the same network. If the connection drops, straightforward reconnect from your phone's Cast menu.

USB cable connection for Android and iPhone

Connecting your phone with a USB cable is the most reliable method and works with both Android and iPhone. For Android, you will need to enable USB Debugging in Developer Options. On your phone, go to Settings, About Phone, and tap Build Number seven times. This unlocks Developer Options. Go back to Settings, open Developer Options, and turn on USB Debugging.

Once USB Debugging is on, plug your phone into your PC with a USB cable. On your phone, you may see a prompt asking whether to allow USB debugging from this computer—tap Allow. Your PC should recognize the phone as a connected device. You can then use free tools like Scrcpy (which you read and run from your PC) to display and control your phone screen on your monitor.

For iPhone, a USB cable connection does not automatically mirror the screen the way it does with Android. Instead, you can use third-party apps like Reflector or Quicktime (on a Mac). Some iPhones can also use AirPlay if your PC has AirPlay-compatible software installed, but this is less common on Windows.

Third-party apps that work without Wi-Fi

If you need to mirror your phone without being on the same Wi-Fi network, or if you want to control your phone from your PC keyboard and mouse, third-party software is your best option. Scrcpy is free and open-source; you read it to your PC, connect your phone via USB, and it displays your phone screen with full control. You can type, click, and drag on your PC to interact with your phone.

AnyDesk and TeamViewer are paid or freemium apps that work over the internet, so your phone and PC do not need to be on the same network. These are useful if you want to control your phone remotely from a different location. They also tend to have lower latency (less delay between your action and what appears on screen) than wireless casting.

Microsoft's Phone Link app (built into Windows 11) can mirror Android phones and also show your phone's notifications and messages on your PC. It requires you to sign in with a Microsoft account and works best when both devices are on the same network, though some features work over the internet.

Why your phone screen might not appear

If casting is not working, first check that both devices are on the same Wi-Fi network and that Wi-Fi is turned on. Restart both your phone and PC—this fixes most connection problems. Make sure your phone's Cast or Screen Cast feature is actually turned on; some phones hide it in a quick-settings menu you have to swipe down to see.

If you are using a USB cable, make sure USB Debugging is enabled on your phone and that you have tapped Allow on any prompts asking for permission. Try a different USB cable or port on your PC; some cables are charging-only and do not carry data. If you are using third-party software, check that you have downloaded the latest version and that your phone's operating system is up to date.

Firewalls on your PC can also block casting. If nothing else works, temporarily disable your firewall to test whether that is the problem. If casting works with the firewall off, you may need to add an exception for the casting app in your firewall settings.

Performance and battery drain when mirroring

Wireless casting uses more power than a USB connection because your phone is constantly sending video data over Wi-Fi. If you plan to display your phone screen for more than an hour, use a USB cable instead, or plug your phone into a charger while casting. The video quality of wireless casting is usually good enough for presentations, but it may lag slightly if your Wi-Fi signal is weak.

USB cable connections are faster and more stable because the data travels directly through the cable rather than over the network. There is almost no lag, and your phone uses less battery. The trade-off is that you are physically tethered to your PC.

If you are using your phone while it is being mirrored, the PC display updates in real time, but there may be a slight delay of a fraction of a second. This is normal and usually not noticeable unless you are playing a fast-paced game or doing something that requires split-second timing.

Frequently Asked Questions

Can I mirror my iPhone to a Windows PC?

Not natively. iPhones do not have built-in support for mirroring to Windows PCs. You can use a USB cable with third-party apps like Reflector, or you can use AirPlay if your PC has AirPlay software installed. The easiest option is usually a cable connection with a third-party app.

Do I need to be on Wi-Fi to cast my phone screen?

For wireless casting, yes—both devices must be on the same Wi-Fi network. If you use a USB cable or a third-party app like AnyDesk, you do not need Wi-Fi. A USB cable works anywhere, and internet-based apps work as long as both devices have internet access.

Can I use my keyboard and mouse to control my phone when it is mirrored?

With wireless casting alone, no—you can only view your phone's screen. With a USB cable and Scrcpy, or with apps like AnyDesk, you can control your phone fully from your PC keyboard and mouse. Check which method you are using to see whether control is included.

Will mirroring my phone drain its battery quickly?

Wireless casting drains battery faster than normal use because your phone is sending video data constantly. A USB cable connection uses less battery because the power comes partly from the cable. If you are mirroring for a long time, plug your phone in or use a cable connection.

What is the difference between casting and screen mirroring?

Casting and screen mirroring are often used interchangeably, but casting usually means sending your phone's display to another device wirelessly, while mirroring can refer to any method of displaying your phone screen on another device, including wired connections. Both show your phone's screen on your PC.
