1. Built-in Windows capabilities: Miracast and "Projecting to this PC"

Modern versions Windows (starting from Windows 10 Anniversary Update) support technology Miracast — a standard for wireless video and audio transmission via Wi-Fi. This is the most reliable connection method without third-party software, but it doesn't work on all devices.

To check compatibility, run (Win + R → cmd → Enter):

netsh wlan show drivers

Find the line in the results Miracast support. If it is indicated there Yes, your laptop is ready to connect. If No - try updating your Wi-Fi adapter drivers via device Manager or use alternative methods from this article.

Connection instructions:

  • 📱 On your smartphone Android open Settings → Connections → Screen Sharing (on Samsung) or Settings → Display → Wireless Display (on Xiaomi/Google Pixel).
  • 💻 On a laptop, press Win + K and select Projecting to this computer. Turn on the option Available everywhere (in system settings).
  • 🔄 Your laptop's name will appear in the list of available devices on your smartphone. Select it and confirm the connection.

The laptop and smartphone are connected to the same Wi-Fi network. "Project to this PC" mode is enabled on the laptop. The Wi-Fi adapter drivers are updated. Developer mode is enabled on the smartphone (for some models).

Miracast Limitations:

  • ⚠️ Doesn't work on iPhone — Apple does not support this standard.
  • ⚠️ Maximum resolution — 1920×1080 at 30 Hz (on some laptops it is possible 60 Hz, but with artifacts).
  • ⚠️ Image lag (~50–100 ms) makes this method unsuitable for dynamic games.

2. Using AirPlay for iPhone (only on macOS or Windows with additional software)

Owners iPhone can take advantage of the technology AirPlay, but there's a catch: by default, it only works between devices AppleTo broadcast the screen to Windows, you will need third-party software like 5KPlayer or ApowerMirror.

For macOS the instructions are simpler:

  1. Make sure the laptop and iPhone connected to the same Wi-Fi network.
  2. On Mac open System Preferences → Monitors and select Duplicate screen (if mirroring is needed).
  3. On iPhone swipe down from the top right corner (on models with Face ID) or up from the bottom edge (on models with Touch ID) to open Control center.
  4. Click Screen mirroring and choose yours Mac from the list.

For Windows you will need:

  • 🖥️ Install an AirPlay receiver program (for example, 5KPlayer — free version with limitations).
  • 📱 On iPhone perform the same steps as for macOS, but select the PC name from the list.
  • ⚙️ Enable the option in the program settings on your laptop Enable AirPlay.
Why might AirPlay not work on Windows?

Many AirPlay receiver apps for Windows use uncertified protocols, which Apple regularly blocks in new versions of iOS. If your iPhone stops connecting after an update, try downgrading to a previous version of the app or using alternative methods (for example, USB + QuickTime Player).

Important: When connecting an iPhone to Windows via AirPlay, audio may be delayed by up to 2 seconds. This is due to the way audio is encoded in non-original receivers.

3. Screen Mirroring Apps: A Comparison of 5 Popular Solutions

If built-in methods aren't suitable, third-party apps can help. We tested the five most popular and compiled a comparison table:

Application Android support iOS support Latency (ms) Max. permission Free version
ApowerMirror ✅ ✅ (with restrictions) 80–120 1080p Yes (watermark)
TeamViewer QuickSupport ✅ ✅ 150–300 720p Yes (for personal use)
Scrcpy ✅ (requires USB for setup) ❌ 30–60 4K Yes (open source)
LetsView ✅ ✅ 100–200 1080p Yes (advertisement)
Vysor ✅ ❌ 50–100 1080p Yes (time limit)

The best balance between quality and speed was shown by Scrcpy, but it requires initial setup via USB (although it works via Wi-Fi afterwards). For iOS the optimal choice was ApowerMirror, despite the watermark in the free version.

Example of setup Scrcpy:

  1. Download the program from official GitHub (link at the time of publication).
  2. Connect your smartphone to your laptop via USB and allow it. USB debugging in the developer settings.
  3. Launch Scrcpy from the command line with the parameter for wireless connection: 
    scrcpy --tcpip
  4. Disconnect the USB cable and connect via Wi-Fi: 
    scrcpy --tcpip=SMARTPHONE_IP_ADDRESS:PORT

    (You can find the IP in the Wi-Fi settings on your phone).

4. Connection via Google Cast (Chromecast) and similar

If you have a device Google Chromecast or a TV with a built-in Google Cast, you can use it as an intermediary to mirror your screen to your laptop. This method works for both types of smartphones, but requires additional equipment.

Algorithm of actions:

  • 📺 Connect Chromecast to the laptop's HDMI port (via an adapter, if necessary).
  • 📱 On your smartphone in the app Google Home or in the notification panel, select the option Share your screen.
  • 🔄 Choose yours Chromecast from the list of devices.
  • 💻 Open a browser on your laptop Chrome and go to the address chromecast.com/setupto customize the display.

For iPhone you will need to install the application Google Home and perform similar actions. The main advantage of this method is minimal latency (~40 ms), allowing for comfortable watching videos or playing undemanding games.

5. Troubleshooting: Why your smartphone won't connect to your laptop

Even with proper setup, errors can still occur. We've compiled a list of the most common issues and solutions:

Problem Possible cause Solution
The laptop does not see the smartphone in the list of devices. Discoverable mode is disabled or different Wi-Fi networks are connected Make sure both devices are connected to the same network. On Windows, enable Network → Sharing Settings → Network Discovery.
The connection drops after a few seconds. Weak Wi-Fi signal or interference Reconnect to a 5 GHz network (if your router supports it). Reduce the distance between devices.
Mirroring works, but there is no sound. Setting the default audio output On the laptop in Control Panel → Sound Select the Miracast/AirPlay device as the primary one.
The smartphone screen is displayed with artifacts Lack of Wi-Fi bandwidth Close background apps on both devices. Try lowering the streaming resolution in settings.

If none of the methods worked, check:

  • 🔧 Update your laptop's Wi-Fi adapter drivers (especially important for Realtek And Broadcom).
  • 📶 Restart your router - sometimes problems are caused by network outages.
  • 🛠️ On your smartphone, enable developer mode and activate the option Debugging over Wi-Fi (For Android).
How to enable USB debugging on Android?

1. Open Settings → About phone and press 7 times Build number.

2. Return to Settings → System → Developer Options.

3. Turn on USB debugging and confirm permission when connecting to the laptop.

6. Alternative Methods: When Wi-Fi Isn't Enough

If wireless connection is not possible due to technical limitations, consider alternatives:

  • 🔌 USB cable + MHL/Slimport: For older smartphones (Android (up to 2018) adapters can be used MHL or Slimport, which convert the USB signal to HDMI. Modern phones (for example, Samsung Galaxy S20+) support USB-C to HDMI directly.
  • 🖥️ DLNA/UPnP: Protocols for transferring media files (not screen!). Supported by applications like BubbleUPnP (Android) or iMediaShare (iOS). Allows you to stream video/photos to your laptop, but does not duplicate the interface.
  • ☁️ Cloud services: For presentations, you can upload files to Google Drive or OneDrive and open them on a laptop. The downside is that it requires internet access and isn't suitable for interactive content.

For iPhone the only reliable wired method is Lightning/USB-C to HDMI adapter from Apple (The official accessory costs ~3,000–5,000 ₽). It supports screen output at resolutions up to 4K at 60 Hz, but requires connection to a power source.

7. Performance Optimization: How to Reduce Lag

Even if the connection is successful, you may encounter image delay or slowdownsHere's how to improve transmission quality:

On the smartphone side:

  • 📴 Close all background applications (especially instant messengers and games).
  • 🔋 Turn on the mode Battery saving - this will reduce the load on the processor.
  • 📶 Connect to the network 5 GHz (if your router supports it). It's less congested and provides greater throughput.

On the laptop side:

  • 🖥️ Disable power saving mode for your Wi-Fi adapter in Device Manager.
  • 🎮 If you use third-party software (for example, Scrcpy), run it with the FPS limit parameter: 
    scrcpy --max-fps 30

    This will reduce the load on the network.

  • 🔌 Connect your laptop to a power source to prevent processor throttling.

For gaming or watching videos we recommend:

  • 🎮 Reduce the transmission resolution to 1280×720 (in the mirroring application settings).
  • 🔊 Disable Wi-Fi audio if you don't need it (this will reduce the load by ~20%).
  • 📡 Use a hotspot on your smartphone instead of a router (if your laptop supports connection to hotspot).
