There are several proven ways to establish communication between personal computer and TV-panel using your home network. The specific method you choose depends on your device's operating system, TV model, and the type of content you're streaming. In this article, we'll cover native Windows features, DLNA protocol capabilities, Miracast technology, and specialized apps in detail to help you choose the best option.
Pre-configuration of the network and devices
The foundation of any wireless data transfer is a stable and properly configured local network. First, make sure your router is working properly and your internet connection is fast enough to handle heavy, high-definition video content. It's crucial that both your computer and TV are connected. Samsung were connected to the same Wi-Fi access point; using a guest network or different frequencies (2.4 GHz and 5 GHz) in some older routers can result in the devices simply not "seeing" each other.
Check that the software on both devices is up to date, as the Wi-Fi module drivers may be outdated or the firmware may be old. Tizen OS may block discovery functions. On your TV, go to the network settings menu and ensure the connection status is active and the IP address is obtained automatically. On your computer, update the wireless adapter drivers through Device Manager or the motherboard manufacturer's official website.
⚠️ Attention: If your router has AP Isolation, devices on the Wi-Fi network will be unable to communicate with each other. You'll need to go to your router settings and disable this option so your computer and TV can see each other.
After a basic check, it's a good idea to reboot the router, even if it's working properly, to clear any cached addressing errors. This simple procedure often resolves issues where devices are online but don't appear in the list of available devices.
Using Connect to a Wireless Display in Windows
The most universal and built-in way to broadcast images from a PC screen to a TV is the technology Miracast, which in Windows is known as "Wireless Display Connection." This method allows you to completely duplicate your desktop or extend it by turning your TV into a second monitor. To use this feature, your TV must support the Wi-Fi Direct standard, which is true for most models. Samsung, released after 2015.
To initiate the connection, press the Source button on your TV remote control and select "Connect to a mobile device" or "Screen Mirroring."

After selecting the device, a connection confirmation prompt may appear on the TV screen, which you'll need to accept using the remote. If the image appears but the audio is out of sync, check your audio settings in Windows by right-clicking the speaker icon in the system tray and selecting the TV as the default playback device.

⚠️ Attention: When using wireless screen mirroring, there may be a noticeable delay (lag) between mouse actions and the on-screen cursor. While this isn't critical for working with documents, it's not suitable for fast-paced games.
Stream media files via DLNA and built-in player
If your goal is not to duplicate your desktop, but to view movies, photos, or listen to music stored on your computer's hard drive, the optimal solution is the technology DLNAShe allows the TV Samsung View shared folders on your computer as network storage. In Windows, this feature is implemented through "Media Streaming" in the media player settings.
To set this up, open "Media Streaming Settings" in the Windows Control Panel and enable this feature. The system will automatically detect compatible devices on the network; find your TV in the list and allow it to access content. Afterwards, when you go to the "Media" or "Source" menu on your TV, you'll see a computer appear and can navigate through folders, selecting files to play using the TV's built-in player.
The advantage of this method is that the TV decodes the video itself, relieving the computer's processor. However, it's worth keeping in mind that the built-in player Samsung may not support some rare audio codecs or subtitle formats. In such cases, the image may be displayed but the sound may be missing, or subtitles may not be displayed.
To improve format compatibility, you can install a third-party DLNA server on your computer, such as Universal Media Server or Plex, which have more flexible settings for transcoding video on the fly.
Using third-party applications and snails
When standard Windows tools are unstable or advanced features are required, specialized applications come to the rescue. One of the most popular solutions is LetsView or AirServer, which install a virtual AirPlay or Miracast receiver on your PC. This is especially useful if the native Windows function is malfunctioning or the TV isn't detected by the system.
Another powerful tool is the media center. KodiBy installing it on your computer and configuring a UPnP/DLNA server in its settings, you can access a huge number of file formats directly from your TV. Kodi has its own codecs, which solves playback issues with files that a standard player can't handle. Samsung.

It provides a convenient interface for managing content on your TV from your computer, allowing you to create playlists and even use your PC screen as a remote control.
| Connection method | Latency | Image quality | Difficulty of setup |
|---|---|---|---|
| Miracast (Win+K) | High (noticeable) | Good (compression) | Low |
| DLNA (Stream) | Absent | Original (no loss) | Average |
| HDMI cable | Absent | Ideal | Low |
| Third-party software | Average | Depends on the software | High |
Connecting a Mac to a Samsung TV via AirPlay 2
For computer owners Apple I was luckier, since many modern TV models Samsung (since 2019) have built-in support for the technology AirPlay 2This means you don't need to install any additional apps or drivers to connect your MacBook or iMac. Both devices only need to be on the same Wi-Fi network.
To start casting on a Mac, click the "Screen Mirroring" icon in the menu or in Control Center. Select your TV from the list of available devices. SamsungA code may appear on the TV screen, which you'll need to enter on your computer to confirm pairing. After that, your Mac's screen will be fully displayed on the big screen.
AirPlay 2 also lets you stream video directly from Safari or apps like iTunes (Apple TV), without overloading the system with duplicate desktops. This ensures smoother playback and better picture quality, as the TV buffers the video stream itself.
What to do if AirPlay isn't working?
Make sure AirPlay is enabled on your TV in General -> AirPlay Settings. Also, make sure client isolation is disabled on your router and Bonjour/mDNS is enabled, which is necessary for discovering Apple devices.
If your TV model doesn't officially support AirPlay, you can try installing utilities like "AirScreen" or "AirReceiver" on the TV itself (via the app store), which emulate the Apple protocol.
Solving common connection problems
Despite the simplicity of the technology, users often encounter situations where the computer can't detect the TV or the connection constantly drops. One common cause is a different network type defined by Windows. If your network is marked as "Public," the system blocks device discovery. You need to change the network profile to "Private" in the Wi-Fi settings.
Problems can also be caused by antivirus software or a firewall that perceives the attempt to connect to the TV as a security threat. Try temporarily disabling the firewall or adding an exception rule for the Media Server service and the DLNA protocol. In some cases, resetting the network settings with the command netsh winsock reset in the command line with admin rights.
☑️ Connection diagnostics
⚠️ Attention: Menu interfaces and item names may vary depending on the TV's year of manufacture and Tizen OS version. If you don't find the option you're looking for, search for a similar one or refer to the online manual for your specific model on the official website.
