You'll learn how to set up folder sharing, use projection features, and which third-party apps you might need. Wi-Fi network stability plays a key role here, so we will also pay attention to the technical nuances of the connection.
Preparing equipment and a Wi-Fi network
Before starting the setup, you need to make sure that all devices are in a single information space. Local area network — This is the foundation upon which data transfer between your computer and TV is built. If your devices are connected to different routers or one of them is using mobile data, the connection will fail.
Make sure both devices—the PC and the TV—are connected to the same Wi-Fi network. Ideally, the router should support the standard. 802.11ac or newer, especially if you plan to stream 4K video. Older routers with a 2.4 GHz frequency may not have enough bandwidth to stream heavy content.

It's also worth updating your computer's wireless adapter drivers and TV software to the latest versions. Manufacturers regularly release patches that improve the compatibility of data transfer protocols.
- 📶 Make sure both devices are within a strong signal reception area.
- 💻 Check if the Wi-Fi module is enabled on your laptop or desktop PC.
- 📺 Make sure your Smart TV is running and has internet access.
- 🔒 If the network is password protected, make sure it is entered correctly on all devices.
Using the built-in Media Transfer feature in Windows
The Windows operating system has a built-in tool for organizing file access over a network. This function is based on the protocol DLNA, which is supported by most modern TVs. You won't need to install any additional software if you're using the latest version of Windows 10 or 11.
To activate the feature, go to the control panel and find the streaming section. Select the option to enable streaming in the menu, after which the system will prompt you to configure access settings. Your computer will become visible to other devices on the network.
After enabling the feature, you need to select the folders whose contents will be available for viewing. Typically, these are the standard "Videos," "Music," and "Pictures" libraries. You can add other directories where your movies are stored through the media player settings.

⚠️ Note: Antivirus programs and firewalls may block the connection. If the TV doesn't detect the computer, check your security settings and add an exception for your private network.
Screen casting via Miracast and WiDi
Technology Miracast Allows you to broadcast your entire computer screen to your TV in real time. Unlike DLNA, it transmits a video stream rather than a file, allowing you to display any content, including online movie theaters, browsers, and games. In Windows, this feature is called "Connect to a wireless display."
For this technology to work, your computer's graphics card and wireless adapter must support the Wi-Fi Direct standard. Most modern laptops and desktops with Wi-Fi modules already support this feature. On a TV, this feature may be called something like Screen Share, Smart View, wireless monitor, or screen mirroring.
The connection process is extremely simple and doesn't require complex network configuration. Simply press a key combination on your keyboard and select the device from the list. The system will automatically find an available display and establish a connection.

What to do if the connection is interrupted?
Frequent connection drops may be caused by Wi-Fi channel congestion. Try switching your router to a different channel in the settings or moving your computer closer to the access point. Also, make sure background processes aren't consuming all your bandwidth.
Setting up a home media server using third-party programs
Built-in Windows tools sometimes become unstable or don't support certain subtitle and audio formats. In such cases, specialized server programs come to the rescue. Plex, Kodi And Universal Media Server — are leaders in the field of home theater organization.
These apps don't just share files; they also beautifully design your library, including posters, descriptions, and cast lists. This transforms viewing files from your hard drive into a full-fledged online cinema experience. Installing the server on your PC and the client on your TV (if available in the app store) ensures optimal compatibility.
Setting up the server usually takes a few minutes. The program will automatically scan the specified folders and index the media files. After that, your movie collection will appear on your TV in the client app.
| Program | Difficulty of setup | Format support | Availability of an interface |
|---|---|---|---|
| Plex | Low | High | Advanced |
| Kodi | Average | Very high | Customizable |
| Windows Media | Low | Basic | Absent |
| Serviio | High | High | Base |
Using specialized software is especially important if you store movies in rare formats or with a non-standard codec. The server can stream video in real time, converting it on the fly to a format the TV can understand.
Broadcasting via Google Chrome browser
If installing programs seems unnecessary to you, and the built-in Windows functions do not work, you can use the browser Google ChromeIt has a built-in feature for casting tabs or the entire desktop to Chromecast-enabled devices. Many modern Smart TVs already have built-in support for this technology.
To start broadcasting, simply open your browser menu and select "Broadcast." A list of available devices will appear. You can broadcast a specific tab, the entire screen, or a specific file.
