How to stream video from your laptop to your TV without cable via Wi-Fi: 7 working methods

Wirelessly streaming video from your laptop to a big-screen TV is a convenient way to enjoy movies, presentations, or games without the hassle of wires. However, not everyone knows that this doesn't require buying additional adapters or running HDMI cables across the room. Modern technologies Miracast, DLNA, Google Cast and built-in functions Smart TV allow you to organize a stable video stream over your home Wi-Fi network.

In this article, we will examine all the current methods of wireless broadcasting - from standard tools Windows 11/10 And macOS to universal apps like Plex or VLCYou'll learn how to avoid image lag, why video may appear choppy, and which router settings can improve streaming quality. And if your TV doesn't support Smart functions, we will show workarounds using inexpensive devices like Google Chromecast or Amazon Fire Stick.

Important: Before setting up, make sure that both the laptop and TV are connected to one Wi-Fi networkIf you have a dual-band router (2.4 GHz + 5 GHz), it is better to use 5 GHz - It provides lower latency and a more stable signal for high-definition video streaming.

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

If you have a laptop on Windows 10/11, the easiest way to broadcast is technology MiracastIt's built into the system and doesn't require any additional software. Miracast works on a point-to-point basis: the laptop connects directly to the TV via Wi-Fi, bypassing the router, reducing latency.

To check support Miracast on the laptop:

1. Click Win + R, enter dxdiag and press Enter.
2. In the window that opens, go to the tab Save all... (Save All Information).
3. Open the saved file and find the line Miracast: Available.

If support is available, please follow these steps:

• 📺 On your TV: Turn on the function Screen Mirroring (at Samsung — Smart View, at LG — Screen Share, at Sony — Miracast). It is usually located in the menu. Network → Wireless.
• 💻 On a laptop: press Win + K (or Win + P → Connect to a wireless display). Select your TV from the list of available devices.
• ⚙️ When connecting for the first time, you may be asked to enter a PIN code, which will be displayed on the TV screen.

If your TV doesn't appear in the list, try:

• 🔄 Reboot the router and both devices.
• 📶 Switch to frequency 5 GHz in the Wi-Fi settings (if the router supports it).
• 🔧 Update your laptop's graphics card and Wi-Fi adapter drivers (especially important for older models) Intel HD Graphics).

⚠️ Attention: On some laptops with AMD Radeon or NVIDIA Miracast may be unstable. In this case, use alternative methods (see sections below).

2. Google Cast and Chromecast: a universal solution for any TV

If your TV does not support Miracast or you want to stream a specific video (not the entire screen), the best option is technology Google CastIt works through apps like YouTube, Netflix or Google Chrome, and to receive the signal you need either Smart TV with built-in Chromecast, or an external adapter Google Chromecast (from 3,000 ₽).

How to broadcast via Google Chrome:

1. Install a browser Google Chrome on your laptop (if not already installed).
2. Connect Chromecast to the TV's HDMI port and set it up through the app Google Home on a smartphone.
3. Open in Chrome video (for example, on YouTube or local file).
4. Click on the icon Broadcast (in the upper right corner of the player) and select your Chromecast.

Advantages of the method:

• 🎞️ You can stream just a browser tab, and not the entire screen (saves laptop resources).
• 📱 Control playback from your phone via apps (YouTube, Spotify and others).
• 🔄 Automatic video scaling to fit TV resolution.

Flaws:

• 🚫 Not all sites support streaming (for example, Twitch or some online cinemas may block Cast).
• 📶 Requires a stable Wi-Fi connection: if the signal is weak, the video will lag.

⚠️ Attention: If you are streaming local files via Chrome, they must be in supported formats (.mp4, .webm). For other formats (.mkv, .avi) use VLC with plugin Chromecast.

3. DLNA and media servers: stream files without screen mirroring

If you don't need to duplicate your entire laptop screen, but only stream movies, music, or photos, the best option is a technology DLNAIt allows you to turn your laptop into a media server that connects to your TV. The main advantage: no delays during playback, since the file is transmitted directly, rather than streamed in real time.

To set up a DLNA server on a laptop:

1. Install the media server program:
   • Plex (paid, but with free features)
   • Kodi (free, open source)
   • VLC (built-in DLNA server)

DLNA does not support DRM-protected files (such as those downloaded from Netflix or Apple TV+). To view them, use official apps on your TV.

Example of setup VLC as DLNA servers:

1. Open VLC, go to View → Advanced Settings.
2. Enable the option Allow remote access via HTTP.
3. Specify the folder with media files in Media → Open Folder.
4. On TV in the app DLNA find the server VLC media player.

⚠️ Attention: Some TVs (for example, older models Philips or Toshiba) may not support formats .mkv or .flac even via DLNA. In this case, use Plex with transcoding.

4. AirPlay for Apple owners (macOS and iPhone)

If you have a laptop MacBook or iMac, and the TV supports AirPlay 2 (For example, Samsung QLED 2018+, LG OLED 2019+ or Apple TV), broadcasting takes literally 2 clicks. This technology is optimized for devices Apple and provides minimal delays (up to 20 ms), which is critical for games or video chats.

How to broadcast your screen Mac on TV:

4. Select your TV from the list. If prompted, enter the PIN code on the TV screen.

Peculiarities AirPlay:

• 🎮 Supports screen mirroring with frequency 60 Hz (important for dynamic content).
• 🔊 Streams audio along with video (unlike some analogues).
• 📱 Can be used for streaming with iPhone or iPad.

If the TV does not support AirPlay, buy Apple TV 4K (from 12,000 ₽) is the most reliable way for the ecosystem AppleAn alternative is adapters like Roku Streaming Stick+, which emulate Apple TV.
