How to connect a laptop to a TV via Wi-Fi: all working methods

Wirelessly streaming images from a laptop to a TV via Wi-Fi is a convenient way to transform your TV screen into a large monitor for work, gaming, or viewing content. However, many users encounter issues: the TV doesn't recognize the laptop, the picture lags, or the sound cuts out. In this article, we'll look into this. all current connection methods — from built-in technologies (Miracast, DLNA, AirPlay) to third-party programs, and we'll also tell you how to fix common errors.

It is important to understand that the connection method depends on three factors: laptop operating system (Windows, macOS, Linux or even Android), TV models (on Android TV, webOS, Tizen or proprietary firmware) and wireless protocols it supportsFor example, old TVs Samsung 2018 may not be supported Miracast, but they work DLNA, A Apple TV requires AirPlayWe'll cover each scenario in detail, from the simplest to the most advanced.

If you've never set up a wireless connection before, start with the first section—it'll explain the basics. Experienced users can skip ahead to Miracast instructions or program review for streaming.

Basic requirements: what you need to connect your laptop to your TV via Wi-Fi

Before you start setting up, please check four key conditions:

• 📶 Shared Wi-Fi networkThe laptop and TV must be connected to one router (or to one access point). Exception - Miracast, which operates on the point-to-point principle (more on that below).
• 🖥️ Protocol compatibilityThe TV must support at least one of the following technologies: Miracast, DLNA, AirPlay or Google CastYou can check this in the TV manual or in the menu. Settings → Network → Wireless.
• 🔧 Current driversThe laptop must have the latest drivers installed for Wi-Fi adapter And video cards (especially important for Miracast).
• 🔌 NutritionWhen connecting the TV for the first time, it's best to plug it into a power outlet—some models disable the Wi-Fi module in power-saving mode.

A critical detail: if your TV was released before 2019, the probability of Miracast support is less than 50%. In this case, use DLNA or third-party programs like ApowerMirror.

Also note that broadcast quality depends on the Wi-Fi speed. To transfer video in 4K a network will be required 5 GHz at a speed of no less than 300 MbpsIf your router is older than 5 years, you may need to upgrade it or use a cable. HDMI for stability.

Method 1: Miracast – Direct Connection Without a Router

Miracast — is a wireless image transmission standard that operates on a point-to-point basis (no router required). It is built into Windows 8.1/10/11 and most modern TVs on Android TV, webOS (LG) or Tizen (Samsung). The main advantage is minimal latency (suitable for gaming), but the disadvantage is that not all devices support the technology.

To connect:

1. Activate the mode on your TV Miracast (may be called Screen Mirroring, Wireless Display or Screen mirroring). This is usually done through:

   Settings → Connections → Screen Mirroring

   On Samsung the path may differ: Settings → General → External devices → Screen Mirroring.

2. On a laptop with Windows click Win + K (or open Settings → System → Project to this PC) and select your TV from the list.
3. Confirm the connection on both devices. If prompted for a PIN, enter it on the TV screen.

If Miracast doesn't work:

• 🔄 Update your driver Wi-Fi adapter on a laptop (download from the manufacturer's website, not through Windows Update).
• 📱 Check if your TV supports it Miracast - some models Sony 2020–2022 models require enabling the function in the service menu.
• 🚫 Disable your VPN and firewall—they may be blocking the connection.

The laptop's Wi-Fi adapter supports Miracast (check in Device Manager)

The TV is in Screen Mirroring mode.

The laptop and TV are no more than 5 meters away

Airplane mode is disabled on the laptop.

On macOS And Linux Miracast not supported natively. For owners MacBook will have to be used AirPlay (see next section) or third-party programs.

How to enable Miracast on 2018–2020 Samsung TVs

• 💻 On MacBook In the menu bar, click on the icon Screen control (or Control Center → Screen Mirroring) and select your TV.

For Windows laptops AirPlay It is not available natively, but you can use emulator programs, for example, 5KPlayer or ApowerMirror (more on this in the section on third-party utilities).

Method 3: DLNA - Transferring media files without mirroring

DLNA (Digital Living Network Alliance) is a protocol for transmitting media files (video, music, photos) from a laptop to a TV via a local network. Unlike Miracast, Here the screen is not broadcast, but only individual files. Suitable for watching movies, but not for gaming or working with documents.

How to set up DLNA on Windows:

2. On your TV, open a media player app (e.g. SmartShare on LG or Video on Samsung) and select your laptop from the list of devices.
3. Select the folder with files on your laptop (by default it is Video, Music And Images in the user profile).

For macOS And Linux a third party will be required DLNA server, For example, Plex or KodiInstall the program, add folders with media files, and connect to them through the corresponding app on your TV.

DLNA limitations:

• ❌ Doesn't broadcast screen - only files.
• ❌ Not all TVs support MKV or FLAC — conversion may be required.
• ❌ Delay in playback of high-bitrate videos (more than 20 Mbps).

Method 4: Smart View (Samsung) and similar models for other brands

TV manufacturers often develop their own wireless connectivity solutions. For example, Samsung This Smart View, at LG — LG TV Plus, at Sony — Screen Mirroring (based on Miracast). These technologies are usually more stable than universal protocols, but they only work with devices of their own brand.

For Samsung TVs (Smart View):

Frequently asked questions

Is it possible to connect a laptop to a TV via Wi-Fi without a router?

Yes, if both devices support Miracast (or Wi-Fi Direct). In this case, a direct connection is created between the laptop and the TV. However, for DLNA, AirPlay or streaming through programs (ApowerMirror) router is required.

Why does the video lag when connected via Wi-Fi, but the sound is fine?

This is a typical issue with slow Wi-Fi speeds. Solutions:

• Switch to frequency 5 GHz (less busy than 2.4 GHz).
• Reduce the broadcast resolution to 720p.
• Connect your laptop to the router via cable Ethernet (if possible).
• Close programs that consume traffic (torrents, cloud storage).

If nothing helps, use HDMI cable.

How to connect a Linux laptop to a TV via Wi-Fi?

On Linux no built-in support Miracast or AirPlay, but you can use:

• Scrcpy (For Android TV) - broadcasts the screen through ADB.
• GNOME Screen Cast (For GNOME) - supports Miracast through gnome-network-displays.
