Wirelessly streaming your laptop screen to your TV via Wi-Fi is a convenient way to turn a large screen into a monitor for presentations, movies, or games. But not everyone knows that this doesn't require expensive adapters or running HDMI cables around the room. Modern TVs Samsung, LG, Sony and even budget models on Android TV support several wireless data transfer protocols, and in laptops with Windows 10/11 or macOS These features are already built in.
In this article we will analyze 5 proven methods connections - from standard Miracast to proprietary technologies like Samsung Smart View or Apple AirPlayYou will learn which method to choose depending on the TV and laptop model, how to fix common errors (for example, "Device not supported" or No sound), and which Wi-Fi router settings can interfere with stable streaming. And if you have an older TV without Smart TV, we'll tell you how to bypass this limitation with minimal effort.
1. Preparation: What you need for a wireless connection
Before trying to connect your laptop and TV via Wi-Fi, check three key conditions:
- 📺 TV must support at least one of the protocols: Miracast (most models after 2013), DLNA (for media files), AirPlay (only Apple TV or TV with tvOS), or proprietary technologies (Samsung Smart View, LG Screen Share).
- 💻 Laptop on Windows 10/11 must have a Wi-Fi adapter that supports Wi-Fi Direct (check in
Device Manager→Network adapters). On macOS version no lower than this is sufficient Mojave 10.14. - 📶 Router must work in the range
5 GHz(Miracast is a must!) and have no restrictions on multicast traffic (otherwise there will be lags).
If your TV was released before 2015 and does not have built-in Wi-Fi, you will need an external adapter - for example, Google Chromecast (from 3,000 ₽) or Mi TV Stick (from 2,500 ₽). These devices connect to the HDMI port and add support Miracast And DLNA.
⚠️ Attention: On some routers (especially from providers), the protocol is disabled by default. IGMP, which is necessary for multicast broadcasts. If the laptop screen connects, but the image is lagging or there is no sound, go to the router settings (usually at192.168.1.1) and turn it onIGMP SnoopingorMulticast Forwarding.
| Device | Minimum requirements | Supported protocols |
|---|---|---|
| Samsung TVs (2016–2026) | Smart TV on Tizen 2.3+ | Miracast, Smart View, DLNA, AirPlay 2 (QLED 2018+ models) |
| LG TVs (2015–2026) | webOS 3.0+ or NetCast | Miracast, LG Screen Share, DLNA, AirPlay 2 (OLED 2019+ models) |
| Sony TVs (2017–2026) | Android TV 7.0+ | Miracast, Google Cast, DLNA, AirPlay 2 (X800H+ models) |
| Windows laptops | Windows 10 (1803+) or 11, Wi-Fi 5 (802.11ac) | Miracast, DLNA (via apps) |
| MacBook | macOS Mojave 10.14+ | AirPlay, Miracast (with additional software) |
2. Method 1: Miracast is a universal protocol for Windows and Android TV
Miracast — is a wireless screen sharing standard supported by most modern devices. It works on the principle point-to-point, that is, the laptop and TV are connected directly, without a router (although its presence doesn't interfere). The main advantage is minimal delays (up to 50 ms), which is critical for games or presentations.
To connect:
- Turn on the TV mode Miracast (names may differ):
- 📺 Samsung:
Settings → General → Screen MirroringorSmart View. - 📺 LG:
Settings → Networks → Screen Share. - 📺 Sony Android TV:
Settings → Network & Sharing → Miracast.
- 📺 Samsung:
Win + K (or open Settings → System → Project to this PC) and select your TV from the list.If your TV does not appear in the list, check:
- 🔄 Restart both devices and the router.
- 📶 Make sure your laptop and TV are connected to the same Wi-Fi network (even if Miracast works without it, some models require a common network to be detected).
- 🔧 Update the drivers for your laptop's Wi-Fi adapter (download from the manufacturer's website, not through
device Manager).
⚠️ Attention: On laptops with processors Intel 7th generation and later models may lack Miracast support due to an outdated Wi-Fi module. Check compatibility on the website. Intel by adapter model (for example, Intel Dual Band Wireless-AC 8265).
The TV and laptop are connected to the same Wi-Fi network (5 GHz)
Miracast/Screen Mirroring mode is enabled on the TV.
The laptop's Wi-Fi and video card drivers have been updated.
VPNs and firewalls are disabled (they may be blocking the connection)
