Do you want to watch movies from your laptop on a big TV screen, but don't want to mess with wires? Wireless connection via Wi-Fi — the ideal solution. However, not everyone knows that several technologies exist for this: Miracast, DLNA And Wi-Fi DirectEach has its own characteristics, pros, and cons, and the choice depends on your TV model, laptop operating system, and even router.
In this article, we will analyze all three connection methods and provide step-by-step instructions with pictures (for popular brands) Samsung, LG, Sony And Xiaomi), and we'll also tell you how to troubleshoot common errors—from no sound to disconnected connections. If you've already tried connecting and it didn't work, there's a solution at the end of the article. FAQ with solutions for 90% of problems.
Before you begin, check two key points: 1) Make sure both your laptop and TV are connected to the same Wi-Fi networks (For DLNA). 2) Update your TV's firmware and your laptop's wireless adapter drivers—this will eliminate half the potential problems.
1. Miracast: Screen Mirroring Without a Router
Miracast - is a wireless transmission standard for image and sound that works without the participation of a router (the TV and laptop are connected directly). The technology is supported by most modern TVs (starting from 2013-2014) and all laptops Windows 10/11 or macOS (with restrictions).
Advantages of the method:
✅ No router dependency—connection works even in the field or at the dacha.
✅ Minimal latency (up to 50 ms), which is important for games and dynamic videos.
✅ Transmitted full screen laptop, not just media files.
Flaws:
❌ On macOS additional software is required (for example, AirParrot).
❌ Not all older TVs support Miracast (especially models before 2015).
❌ If the signal is weak, artifacts may appear on the screen.
- 📺 For TVs Samsung: the function is called
Screen Mirroring(on the menuSource → Screen Mirroring). - 🖥️ For Windows: use a combination
Win + Kor the waySettings → System → Display → Connect to a wireless display. - 🍎 For MacBook: third-party software will be required (for example, Reflector or AirServer).
Turn on Wi-Fi on your laptop and TV
Activate Screen Mirroring/Miracast mode on your TV
Update the wireless adapter driver on your laptop (via Device Manager)
Close resource-intensive applications (torrents, games) for a stable connection-->
2. DLNA: Streaming Movies Over Your Home Network
DLNA (Digital Living Network Alliance) is a protocol for exchanging media files between devices on the same network. Unlike MiracastHere, it's not the laptop screen that's being transferred, but specific files (movies, music, photos). This method is ideal if you simply need to play a movie on TV without fiddling with your laptop's settings.
How does this work:
1. The laptop and TV are connected to the same router.
2. It starts on the laptop DLNA server (built-in or third-party).
3. The TV finds the server on the network and opens access to folders with movies.
Support by brands:
- Samsung: function AllShare (old models) or Smart View.
- LG: SmartShare or LG Content Store.
- Sony: Media Player or Video in the applications menu.
- Xiaomi: built-in Mi Home Media.
| Laptop OS | Built-in DLNA server | Recommended software |
|---|---|---|
| Windows 10/11 | Yes (Media streaming in the parameters) |
Serviio, Plex |
| macOS | No | Plex Media Server, Kodi |
| Linux | No | MiniDLNA, Rygel |
3. Wi-Fi Direct: Direct connection without a router
Wi-Fi Direct Wireless LAN is a technology that allows devices to connect directly, without a router as an intermediary. Essentially, it's an "access point" from the TV to which the laptop connects. This method is universal, but requires support from both devices.
Where to find the function:
- On TV: usually in the menu Network → Wi-Fi Direct (on Samsung can be called Wi-Fi Direct Pro).
- On a laptop: connect as to a regular Wi-Fi network (the TV's SSID will be visible in the list).
Warnings:
⚠️ Attention: after connecting via Wi-Fi Direct the laptop will lose access to the internet (if not used Bridge of Networks in Windows).
⚠️ Attention: some televisions (for example, LG OLED 2018–2019) limit the transmission speed by Wi-Fi Direct up to 5 Mbps - this is enough for Full HD, but not for 4K.
- 🔧 For Windows: after connecting to Wi-Fi Direct open
Settings → System → Display → Connect to a wireless display. - 📱 For Android: use the app Google Home or SmartThings (For Samsung).
- 🖥️ For Linux: manual configuration will be required via
wpa_supplicant.
How to enable network bridging in Windows to save internet access
1. Open Control Panel → Network and Sharing Center → Change adapter settings.
2. Select your Wi-Fi Direct connection and your primary internet connection (e.g. Ethernet).
3. Right-click → Setting up the bridge.
4. Wait 10–20 seconds – the Internet will appear on your laptop.
