Modern multimedia systems make it easy to stream content from a personal computer to a large TV screen, eliminating unnecessary wires and complex wiring. Wireless connection has become the standard for transmitting high-definition video, photos, and music over a home network. The technology Samsung Smart TV offers several built-in protocols such as DLNA, Miracast and AirPlay 2, which make this process much easier.
To successfully implement this idea, you won't need to purchase any additional equipment as long as both devices support Wi-Fi Direct standards or are on the same local network. In this article, we'll cover all available synchronization methods in detail, from simple screen mirroring to setting up a media server. Connection stability It directly depends on the quality of your router and the distance between devices.
Before you begin setup, make sure your router supports the 5 GHz frequency, as transmitting 4K video streams requires high channel bandwidth. Signal interference Connections from neighboring networks can cause delays or image desynchronization. We'll cover both software and hardware aspects of creating a reliable bridge between your PC and TV.
Network requirements and equipment preparation
The foundation of any wireless broadcast is a properly configured local network. The first step is to ensure that your computer and TV are Samsung connected to the same router. If the devices are on different subnets (for example, one on a guest network and the other on the main network), discovery may not work.
Please pay attention to the Wi-Fi standard: for comfortable viewing of video in Full HD or 4K resolution, it is highly recommended to use the range 5 GHzThe 2.4 GHz band is often congested, causing image artifacts when streaming. Check your router settings and ensure WMM (Wi-Fi Multimedia) mode is enabled, as it prioritizes multimedia traffic.
⚠️ Note: Some corporate or public Wi-Fi networks have AP Isolation, which prevents devices from seeing each other. Under these conditions, wireless connection is impossible without changing router settings.
It's also important to ensure that both devices have the latest firmware version installed. The manufacturer regularly releases updates to improve the stability of network modules. This can be checked on the TV via the menu. Support → Software Update.
Screen Mirroring Method via Miracast
The fastest way to display the entire Windows desktop on your TV is with the technology Miracast, which is implemented in Windows 10/11 as the "Connect" feature. This method allows you to completely mirror your monitor screen, which is convenient for demonstrating presentations or playing games.
To start working, press the signal source selection button (Source or the house icon) and select the item Connection Guide → PC → Smartphone or Tablet → Screen MirroringAfter this, the TV will go into connection standby mode.
On your computer, press the key combination Win + KA "Connection" panel will appear on the right side of the screen, where your TV should be displayed. SamsungClick on it to start pairing.
☑️ Pre-mirroring check
Once connected, you can choose between screen mirroring and desktop extension modes. In extended mode, the TV becomes a second monitor onto which you can drag application windows.
Using DLNA technology to play your media library
If your goal is to play a specific movie or music, rather than streaming your entire desktop, then the protocol DLNA (Digital Living Network Alliance) is ideal. It allows the TV to access content folders on the computer and play them using a native player.
In Windows, open "Media Streaming Settings." This can be done through the Control Panel or Search. In the window that opens, select the option to enable streaming and find your TV in the list. Samsung.
Make sure the device status is set to "Allowed." Then, open the video folder, right-click the file, select "Cast to Device," and select your TV. Playback will begin automatically.
| Parameter | Importance for DLNA | Recommendation |
|---|---|---|
| Video formats | MP4, MKV, AVI | Use MP4 for better compatibility |
| Codec | H.264, H.265 | H.265 requires a powerful TV |
| Subtitles | SRT, ASS | The subtitle file name must match the video. |
| Network speed | from 20 Mbps | For 4K content, 50 Mbps is recommended. |
It is important to note that when using DLNA, playback control (pause, rewind) is carried out using the TV remote control, and the computer only acts as a data storage device.
AirPlay 2 support on Samsung TVs
Mac owners or users of Chromium-based browsers can take advantage of support AirPlay 2, which is built into modern Samsung TV models (2019 series and newer). This ensures stable video and audio transmission with minimal latency.
To activate the function on your TV, go to Settings → General → Apple AirPlay Settings and make sure the switch is set to "On." You can also configure the security requirement to require a code when connecting new devices.
What to do if AirPlay isn't working?
Make sure AP client isolation isn't enabled on your router. Also, check that your computer's antivirus software isn't blocking incoming connections for Bonjour or AirPlay services.
On a macOS computer, open "Control Center" in the menu bar, select "Screen Mirroring," and click the name of your TV. In Google Chrome or Microsoft Edge on Windows, you can also cast a tab by selecting an AirPlay-enabled device from the "Cast..." menu.
The advantage of this method is that it supports multi-threading: while a movie is playing on your TV, you can use your computer for other tasks without interrupting playback if only a browser tab is being streamed.
Setting up shared folders and network access (SMB)
For advanced users who want to create a full-fledged home media center, the optimal solution would be to set up a network folder using the protocol SMBThis allows the TV to access the computer's hard drive as local storage.
Create a folder on your drive where you'll store your media files. Right-click it, select "Properties," go to the "Sharing" tab, and click "Advanced." Check the "Share" box and set the necessary permissions for your account.
On your Samsung TV, launch the "Media Player" or "Universal Guide" app and go to the "PC" or "Network" section. Your folder should appear there. When you first connect, the system may ask for your Windows account login and password.
⚠️ Note: SMB version 1.0 is considered insecure and is disabled by default in Windows 10/11. If your TV is older and does not support SMB v2/v3, you will need to manually enable the legacy protocol in Windows components, which reduces overall system security.
Using a network folder allows you to create libraries with movie covers and descriptions when using third-party servers such as Plex or Kodi installed on your PC.
Troubleshooting and connection diagnostics
Despite the ease of setup, users may encounter a number of difficulties. The most common issue is the computer not detecting the TV, or vice versa. In 90% of cases, this is due to Windows Firewall or antivirus settings.
Check your network type in Windows. If your network is marked as "Public," the system is blocking device discovery. You need to switch your network profile to "Private." You can do this in Network & Internet settings.
- 📡 Weak signal: If the TV is located far from the router, use a Wi-Fi repeater or connect the TV with a LAN cable if the wireless module is weak.
- 🔄 Codec incompatibility: If the video is listed but doesn't play, try installing a third-party player on your TV, such as VLC or MX Player, from the app store.
- 🔒 Port blocking: Make sure that the ports required for DLNA (usually 1900 UDP) and Miracast are not blocked in your router settings.
It's also worth mentioning that some router models have a "Guest Network" feature. Devices on the guest network are isolated from the main network, so the connection between the PC and TV will not work in this case.
Comparison of connection methods and final recommendations
The choice of connection method depends on your specific needs. Miracast is best for screen sharing or gaming, while DLNA or SMB are preferable for watching high-quality movies.
AirPlay 2 technology is an excellent alternative for the Apple ecosystem, offering high stability. However, for transferring large files from a hard drive, it is less convenient than a direct network connection.
⚠️ Please note: Menu interfaces and item names may differ slightly depending on the version of the Tizen operating system installed on your Samsung TV.
The table below provides a comparison of the main characteristics of the methods considered:
| Method | Latency | Quality | Convenience |
|---|---|---|---|
| Miracast | Low | High (compression) | High |
| DLNA | No | Original | Average |
| AirPlay 2 | Low | High | High |
| SMB (Folders) | No | Original | Low (setting) |
In summary, wirelessly connecting your Samsung TV to your computer opens up a wide range of multimedia options. Proper network setup and choosing the right protocol will ensure a comfortable viewing experience on the big screen.
Why isn't my Samsung TV showing up in the list of available devices?
