Modern Samsung TVs equipped with the platform Smart TVTVs have become full-fledged multimedia centers, capable of playing content not only from built-in apps but also from external devices. Connecting a computer to a TV via WiFi provides access to a vast library of movies, photos, and music without the need for wires, making the living room more tidy and functional. This is especially important for owners of large screens, when watching videos on a laptop monitor becomes inconvenient.
However, the synchronization process can seem complicated due to the variety of methods and operating system versions. There are several main data transfer protocols, each with its own unique features, from simple DLNA to complex real-time screen mirroring. Understanding these differences will help you choose the optimal method for your needs, whether it's a presentation or watching a 4K movie. In this article, we'll examine all available options in detail and solve common problems.
Before you begin setup, make sure both devices—your PC and TV—are connected to the same wireless network. Samsung Tizen OS Windows 10/11 use the local network to discover devices, so if one of the devices is on a guest network or using mobile data, the connection will fail. Signal stability is also critical, especially when transmitting high-definition video.
Preparatory stage and checking device compatibility
The first step is to verify the technical capability of the connection. Not all Samsung TV models support wireless video streaming, although most devices released after 2016 have a built-in module. WiFi Direct and support for DLNA standards. Windows computers require a WiFi adapter, which is included in almost all modern laptops. However, desktop computers may lack one, requiring an external USB dongle.
It's also important to check the operating system version on your computer. Windows 7 and older versions may have difficulty connecting natively to modern Smart TVs without installing additional software. However, Windows 10 and 11 have a built-in "Projection" feature that works seamlessly with Samsung TVs. Make sure your network card drivers are updated to the latest version.
⚠️ Important: If your router is operating in split-band mode (separate networks for 2.4 GHz and 5 GHz), make sure both your TV and computer are connected to the same frequency. Some older TV models may not be able to see devices in adjacent frequency bands due to client isolation settings on the router.
For macOS users, the situation is a little different, as the Apple ecosystem uses the protocol AirPlay 2Support for this standard has been available in Samsung TVs since 2019 models. If you have an older TV, direct connection via native Apple features will be impossible without third-party apps or Apple TV boxes. Check the list of supported models on the manufacturer's official website.
Cast your Windows screen using the Projection feature
The fastest way to project your computer's content to a Samsung TV is to use the built-in Windows feature called "Projection" (or "Cast"). This method allows you to not only stream media files, but also duplicate your entire desktop or extend it onto a larger screen, making it ideal for presentations or gaming. The technology is based on the Miracast standard, which is supported by most modern Samsung TVs.
To activate this mode on your Samsung TV, you don't need to launch any apps. Simply ensure the TV is turned on and ready to receive a signal. Some models may require you to allow the connection in the security settings. Press the button on the remote control. Home, then go to the sources menu and select the "Connection Guide" or "Connect to a Mobile Device" option if automatic detection does not work.
On a Windows 10 or 11 PC, follow these steps:
- 🖥️ Press the key combination
Win + Kto quickly call the connection panel. - 📡 In the list of wireless displays that appears, find the name of your Samsung TV.
- 🔗 Click on the device name and wait for connection confirmation on the TV screen.
- ⚙️ Once connected, you can select the operating mode: "Second screen only", "Duplicate" or "Extend".
Image quality depends on the power of your WiFi router and your distance from it. This method may introduce some input lag, so it may not be suitable for fast-paced shooters, but it's an excellent solution for strategy games, videos, and document processing. If the image is choppy, try moving your computer closer to the router or switching to the 5 GHz band.
☑️ Check before connection
Using DLNA technology to play your media library
If your goal is not screen duplication, but watching movies or listening to music stored on your computer's hard drive, then the technology DLNA (Digital Living Network Alliance) will be the most effective. It allows the TV to view folders containing media files on the PC as network resources. Unlike mirroring, DLNA doesn't burden the computer's processor with real-time image rendering, but transmits a pre-processed data stream.
In Windows, this feature is implemented through "Media Streaming Settings." To configure access, open Control Panel, find the "Multimedia" section, and select "Media Streaming Settings." In the window that opens, click "Turn on media streaming." The computer will begin searching for available devices on the network.
Once your Samsung TV appears in the list, select it and set its status to "Allowed." You can then configure which folders will be available for viewing. The standard libraries "Video," "Music," and "Pictures" are available by default, but you can add any other directories where your content is stored. To access this data on your TV, go to the source menu and select "Connected Devices" or "Media Player."
| Characteristic | Miracast (Projection) | DLNA (Streaming) |
|---|---|---|
| Purpose of use | Screen mirroring, presentations, games | View photos, videos, and music from files |
| PC load | High (video encoding) | Low (just data transfer) |
| Control | From a computer | From the TV remote control |
| Quality | Depends on the WiFi signal | Original file quality |
The advantage of DLNA is its subtitle support and the ability to control playback directly from your TV remote. You can pause, rewind, or change the volume without leaving the couch. However, the file format must be supported by the TV; if the file uses an uncommon codec, the TV may display a "format not supported" error, even if it plays on your PC.
Connecting macOS and AirPlay 2: Setup Features
Apple Macintosh computer owners are at an advantage thanks to the protocol integration AirPlay 2 AirPlay 2 is available on modern Samsung TVs. This technology enables high-quality image and sound transmission with minimal latency. To use AirPlay 2, your Samsung TV must be a 2019 model or newer, or have updated firmware that supports this standard.
The connection process is as simple as possible. Make sure your Mac and TV are on the same WiFi network. In the macOS taskbar (upper right corner), click the "Control Center" icon (the two toggle switches) and select "Screen Mirroring." Your Samsung TV should appear in the list of available devices. When you first connect, a four-digit code may appear on the TV screen, which you'll need to enter on your computer.
AirPlay 2 functionality on Samsung TVs includes not only mirroring but also using the TV as a separate monitor. You can choose between "Primary Display," "Mirror," or "Extend" modes. "AirPlay to Mac" is also available, allowing you to use your Mac's webcam and microphone from the TV, although this is a secondary feature when connecting a PC to the TV. Audio is also transmitted wirelessly, freeing you from cables.
⚠️ Note: The AirPlay interface and feature availability may vary depending on your Tizen OS version. If you don't see the AirPlay option in your TV settings, check "General" -> "Apple AirPlay Settings" and ensure the switch is set to "On."
If a standard connection isn't working, check your Mac's firewall settings. Sometimes, macOS's security system blocks incoming connections for the device discovery service. In System Preferences -> Security & Privacy -> Firewall, make sure that the option to block incoming connections for AirPlay-related services isn't selected.
What should I do if AirPlay doesn't detect my TV?
Make sure the "AP Isolation" feature is disabled on your router. This feature prevents devices on the same network from seeing each other. Also, try rebooting both the router and TV simultaneously.
Third-party applications and alternative methods
In situations where native methods don't work or functionality isn't sufficient, third-party solutions come to the rescue. One of the most popular apps for Samsung TV is Smart View (Although Samsung is gradually phasing this out in favor of built-in features, it's still relevant for older models) or universal media servers. There are also programs that turn your computer into a DLNA server with advanced capabilities, such as Plex or Kodi.
The Plex app requires a server installation on your computer and a client application on your TV. Once registered, Plex will scan your media libraries, adding cover art, descriptions, and cast members, transforming your movie collection into a beautiful, Netflix-like interface. This is ideal for those with a large video archive stored on their computer.
For users who need to stream content from browsers that don't natively support Casting, a Google Chrome extension is available. Even if you don't have a Chromecast, many Samsung TVs have built-in support for the Google Cast protocol or allow you to cast a browser tab using DLNA-compatible plugins. In the Chrome browser, click the three dots in the corner, select "Save & Share" -> "Cast..." and select your device.
Another powerful tool is the program LetsView or ApowerMirrorThey allow you to connect to your TV via WiFi and broadcast your screen with additional features, such as mouse control with a remote control or screen recording. However, it's important to remember that most advanced features in these programs are paid or have limitations in the free version.
Troubleshooting and connection diagnostics
Despite its apparent simplicity, wireless connections often encounter technical obstacles. The most common issue is that the TV simply doesn't appear in the list of available devices on the computer. In this case, first check whether your antivirus or Windows Firewall is blocking network discovery. In your network settings, the profile should be set to "Private Network" rather than "Public."
The second common issue is audio and video desynchronization or constant buffering. This is a clear sign of insufficient WiFi bandwidth. If the router is located far away or the signal passes through thick walls, the stream quality will suffer. In this case, try moving the router closer to the viewing area or using a WiFi repeater to boost the signal.
Another issue worth mentioning is file formats. When streaming via DLNA, the TV may not recognize MKV files with certain audio codecs (such as DTS), as licensing restrictions prevent Samsung from using them in the built-in player. In this case, installing a third-party player on the TV itself (if the model supports it) or transcoding the file on the fly via the Plex server will help.
⚠️ Note: If you're using a VPN on your computer, local device discovery may stop working because the VPN changes your network gateway. To use DLNA or Miracast, temporarily disable the VPN connection.
Don't forget to update your software. Samsung TV firmware is regularly updated to fix communication protocol errors. Go to Settings → Support → Software Update and check for a new version. The same applies to the WiFi adapter drivers on your computer.
