How to Mirror Your Laptop's Screen to a TV via Wi-Fi: All the Methods + Troubleshooting

Wirelessly streaming your laptop's screen to your TV via Wi-Fi is a convenient way to show a presentation, watch a movie on the big screen, or play games wirelessly. But not everyone knows that you don't need expensive adapters or run HDMI cables throughout the room to do this. Modern Smart TV and laptops support several wireless transmission protocols, and the choice of method depends on the operating system, TV model, and even the version of the Wi-Fi router.

In this article we will look at all current methods broadcasts - from built-in functions Windows 11/10 And macOS to third-party applications like ApowerMirror or TeamViewerWe'll pay special attention to common errors: why the image is lagging, there's no sound, or the TV can't find the laptop on the network.

1. Preparation: What you need for Wi-Fi streaming

Before setting up a connection, please check three key conditions:

• 📺 Smart TV. Most models Samsung (2016 and newer), LG (With webOS 3.0+), Sony Bravia (With Android TV) And Xiaomi Mi TV Support wireless streaming. Check the model in the documentation or in the settings menu. Network → Device Information.
• 💻 Laptop with 5GHz Wi-Fi adapterFor stable video transmission in Full HD or 4K A dual-band router is recommended. If your laptop only supports 2.4 GHz, image delays are possible.
• 🌐 Shared Wi-Fi networkThe laptop and TV must be connected to one router. Guest network or different subnets (eg. 192.168.0.x And 192.168.1.x) block device detection.

If you have an old TV without Smart TV, but with a port HDMI, you can use external adapters like Google Chromecast, Amazon Fire TV Stick or Mi TV StickThey convert Wi-Fi signals to HDMI and add wireless streaming support. These devices cost between 2,500 and 6,000 rubles (as of 2026).

⚠️ Attention: Some budget smart TVs (for example, models on RTK OS or Vidaa) may not support the standard Miracast or AirPlayCheck the specifications of your model on the manufacturer's website.

2. Method 1: Built-in Windows function (Miracast/WiDi)

Laptops under control Windows 10/11 support technology Miracast (or Wireless Display from Intel), which allows you to duplicate your screen without additional programs. This method works with most Smart TV on Android TV, webOS And Tizen.

⚠️ Attention: On some laptops Lenovo And HP function Miracast disabled by default in the BIOS. To enable it, reboot the device, enter the BIOS (button F2/Del at boot) and enable the option Wireless Display or WiDi in the section Advanced.

3. Method 2: AirPlay for macOS and Apple TV

If you have MacBook and a TV with support Apple TV (or Smart TV with built-in AirPlay 2, For example, LG OLED 2019+ or Samsung QLED 2020+), use the protocol AirPlayIt provides minimal latency and supports streaming in 4K HDR.

Instructions for macOS:

• 🖥️ On your MacBook, open System Preferences → Monitors.
• 📺 Turn on the TV AirPlay (on Apple TV: Settings → AirPlay and HomeKit → AirPlay).
• 🔗 In the Mac menu bar, click on the icon Screen management (or Command + F2) and select your TV.
• 🎵 To broadcast audio, in System Preferences → Sound Select TV as the output device.

4. Method 3: Google Cast (Chromecast and Android TV)

Technology Google Cast allows you to broadcast not only your screen, but also individual browser tabs or media files. It is built into Android TV and devices ChromecastThe main advantage is the low load on the laptop, since the content is streamed directly from the internet.

Why is Google Cast better than Miracast?

Google Cast streams content directly from the internet to your TV, eliminating the burden on your laptop. This reduces latency and allows you to continue working on your PC while streaming. Miracast mirrors your screen, which requires more resources and can cause lag on weak Wi-Fi connections.

5. Method 4: Third-party programs (ApowerMirror, TeamViewer, Steam Link)
