It's hard to imagine modern digital leisure without the integration of all devices into a single ecosystem. Wireless connection A connection between your computer and TV provides access to a wealth of media content, allowing you to display movies, photos, and presentations on the big screen without the hassle of cables. This solution is ideal for setting up a home theater or hosting business meetings in the office.
The setup process may seem complicated to a beginner, but it actually consists of several logical steps. You will need a stable Wi-Fi network, a compatible smart TV, and a computer running Windows or macOS. In this article, we'll cover all current synchronization methods, from standard operating system functions to specialized software.
Before you begin setup, make sure both devices are on the same local network. It is critical that the computer and TV are connected to the same router, and not to different guest networks or extenders with client isolation. If you are using a dual-band router, it is advisable to have both devices operating on the 5GHz frequency to ensure high data transfer speeds.
Preparing equipment and network
The first step is to check the technical condition of your equipment. Make sure that your TV Supports Smart TV and has a built-in Wi-Fi module. Most modern models from Samsung, LG, Sony, and Philips come with this feature by default. If you have an older model, you may need an external adapter or a media player.
The computer must also have a working network adapter. This is standard for laptops, while desktop PCs may require an external USB Wi-Fi adapter. Signal quality is crucial: connection interruptions will result in image lag or video buffering.
- ✅ Check that the router is turned on and distributing the Internet.
- ✅ Make sure that Wi-Fi is enabled on both devices.
- ✅ Find out the password for your wireless network to connect.
- ✅ Update your computer's network card drivers to the latest version.
It's important to keep in mind that channel bandwidth depends on the number of connected devices. If files are actively downloaded or online games are running, the quality of the stream to your TV may degrade. In such cases, it's recommended to temporarily limit background activity on other devices.
Setting up Windows DLNA sharing
The Windows operating system has built-in tools for organizing a media server. Technology DLNA (Digital Living Network Alliance) allows you to transfer media files between compatible devices within the same network. This is ideal for viewing photos or movies stored on your PC's hard drive.
To activate this feature, you need to go to the network control panel. Open Control Panel → Network and Internet → Network and Sharing CenterIn the left menu, select "Change advanced sharing settings." Here you need to enable network discovery and file sharing for the current network profile (private or public).
⚠️ Attention: Enabling sharing on public networks (such as cafes and airports) can make your files visible to others. Always check your network type: for a home network, select "Private."
After enabling general settings, you need to select the folders that will be accessible to the TV. Go to the desired folder's properties, select the "Access" tab, and click "Advanced Setup." Check the "Share this folder" box and set read permissions for the "Everyone" group. Now the media files in this folder are visible in the Smart TV interface.
☑️ Setting up DLNA on Windows
Screen casting via Miracast and WiDi
If your goal is not just to display a file, but to completely duplicate your desktop or run a game on a larger screen, you will need technology MiracastIn Windows 10 and 11, this feature is built into the system and requires no additional software. It allows for real-time video and audio streaming with minimal latency.
To start broadcasting, press the key combination Win + K on the keyboard. The "Connection" panel will appear on the right, where the system will begin searching for available wireless displays. Select your TV from the list. A connection confirmation prompt may appear on the TV screen, which you'll need to confirm with the remote.
Projection modes can be configured via the menu. System → Display → Multiple displaysYou can select "Duplicate" mode to display the same image on both your monitor and TV, or "Extend" to use your TV as a second monitor. This is convenient for watching videos in a browser window while working on documents on the main screen.
It's worth noting that Intel's WiDi (Wireless Display) technology is the predecessor to Miracast and is often integrated into the standard on new devices. If you have an older computer, you may need to install Intel Wireless Display drivers, but modern processors support this feature out of the box.
What to do if the TV is not found?
If the search doesn't yield any results, check whether Screen Mirroring or Wireless Display is enabled in the TV settings. On some Samsung models, this is called Smart View, and on LG models, it's called Screen Share. Also, make sure Windows Firewall isn't blocking incoming connections for private networks.
Using Smart TV Browsers and Apps
Many users prefer to stream content directly from their browser or through apps. Google Chrome, Yandex Browser, and Microsoft Edge all have a built-in "Cast" feature. This is especially convenient for streaming videos from YouTube, online movie theaters, or web pages.
To start, open the browser menu (the three dots in the corner), select "Cast," and find your device. Unlike Miracast, this often only casts the contents of a tab rather than the entire desktop, reducing the load on your computer's processor.
Samsung TV owners can use the app Samsung SmartThings, which is available in the Microsoft Store. It not only allows you to mirror your screen but also control some TV functions from your PC. Similar solutions exist for LG (LG TV Plus) and Sony.
| Method | Delay | Quality | Best use |
|---|---|---|---|
| Miracast | Low | High | Presentations, games |
| DLNA | Absent | Maximum | Movies, photos |
| Chrome Cast | Average | Depends on the network | Web content |
| Third-party software | Variable | Customizable | Complex scenarios |
Third-party synchronization programs
The operating system's built-in tools don't always work correctly with all TV models. In such cases, specialized tools come to the rescue. One of the most popular solutions is the program Home Media ServerIt offers a wide range of features and supports streaming virtually any video format, automatically transcoding them on the fly.
Another powerful tool is PlexThis is a full-fledged media library that not only connects devices but also beautifully presents your files, adding cover art, descriptions, and movie ratings. Installing the server on your PC and the client app on your TV (if available in the TV app store) turns your collection into a Netflix-like experience.
For macOS and Apple device users, AirPlay is a popular option. If your TV doesn't natively support AirPlay 2, you can install a set-top box on your Apple TV or use emulators on the TV itself (for example, AirScreen on Android TV).
⚠️ Attention: When installing third-party software, download distributions only from the developers' official websites. Versions from untrusted sources may contain malicious code that exploits your network for mining or data theft.
Setting up such programs usually involves launching the server, scanning folders containing media files, and waiting for the device to appear in the client list. The program interfaces are intuitive and often localized in Russian.
Troubleshooting and troubleshooting
Even with proper configuration, technical issues may still occur. Most often, the problem lies with antivirus software or firewall software blocking the connection between devices. Try temporarily disabling protection or adding your connection to the exceptions list.
If the video is lagging or disintegrating into artifacts, it means there's not enough bandwidth. Try lowering the video bitrate in your streaming software settings or switching your router to a less congested Wi-Fi channel. Restarting the router, which clears the cache and resolves connection errors, also helps.
- 🔧 Update your TV firmware through the support menu.
- 🔧 Restart the Media Server service in Windows (Services.msc).
- 🔧 Check if client isolation (AP Isolation) is enabled on your router.
- 🔧 Make sure your antivirus doesn't mark the network as public.
In some cases, resetting Windows network settings can help. To do this, open the Command Prompt as an administrator and enter the command

Is it possible to connect a computer to a TV without a router?
Yes, this is possible using Wi-Fi Direct technology. This allows the computer and TV to create a direct connection to each other, bypassing the access point. However, data transfer speeds may be lower in this mode, and the connected device will not have internet access.
Why can't the TV see the computer on the network?
Most often, the devices are connected to different networks (for example, one to a guest network and the other to the main network) or network discovery is disabled on the computer. The problem can also be caused by antivirus software or outdated network card drivers.
Does the connection affect internet speed?
Using DLNA or local file streaming doesn't consume internet bandwidth, as data is transferred within the local network. However, streaming online video (YouTube, Netflix) from your computer to your TV consumes data at the standard rate.
What video format is best for DLNA?
The most universal formats are MKV, MP4, and AVI with H.264 or H.265 codecs. These formats are supported by most modern TVs without the need for computer-based transcoding.
