Modern televisions Samsung Smart TV While they are powerful multimedia centers, their capabilities are often limited by built-in memory or specific file formats. PC and laptop owners often need to play a movie, TV series episode, or family photo album stored on the PC's hard drive on the big screen. Wired connections, such as HDMI, provide high quality but are inconvenient due to the need to run cables across the room.
That's why streaming video from a computer to a Samsung TV via Wi-Fi is becoming the most popular solution. Wireless technology eliminates the clutter of cables and allows freedom of movement. There are several proven methods for achieving this: using built-in functions DLNA to advanced screen mirroring via protocol MiracastThe specific method you choose depends on your TV model, your computer's operating system, and your personal preferences.
In this guide, we'll cover all the current connection methods in detail, so you can enjoy content on the big screen without lag or loss of quality. You don't need to be a networking expert, as most modern solutions are plug-and-play or require minimal setup. The key is to ensure a stable connection between your devices.
Network requirements and equipment preparation
Before setting up the stream, you need to ensure your local network is ready to handle a heavy video stream. A fundamental requirement is that both devices—the computer and the Samsung TV—are on the same wireless network. If your router broadcasts signals on both 2.4 GHz and 5 GHz frequencies, and the devices are connected to different bands with client isolation enabled, they may simply not be able to see each other.
Particular attention should be paid to the speed of the Wi-Fi connection. For example, for transmitting high-definition video 4K Ultra HD or HDR, the bandwidth of a standard network may not be sufficient, resulting in constant buffering and image stuttering. Ideally, the router should support the standard. Wi-Fi 5 (802.11ac) or newer, and the computer and TV must be located in an area with a strong signal reception.
It's also important to check your TV's software. Outdated firmware version Tizen OS may contain bugs that prevent Smart View or AllShare features from working correctly. It is recommended to update the system in advance via the settings menu to avoid software conflicts when attempting to connect.
⚠️ Important: If your router has the "Guest Network" feature enabled, devices connected to it are often isolated from the main local network. Make sure your PC and TV are connected to the main SSID, not the guest SSID, otherwise devices will not be discoverable.
- 📶 Make sure your router supports 802.11ac or higher for a stable 4K stream.
- 🔌 Check that both devices are on the same subnet (same gateway IP address).
- 📺 Update your Samsung TV firmware to the latest available version.
DLNA Method: Organizing Your Media Library Over the Network
Technology DLNA (Digital Living Network Alliance) is one of the oldest, but still relevant, methods for transferring media files. In the Samsung ecosystem, this function is often implemented through the service AllShare or simply appears in the list of signal sources as "Media Server." The idea is that the computer acts as a storage device, while the TV simply reads and decodes the video stream, without requiring any additional software to be installed on the TV itself.
To implement this method in the operating system Windows You need to enable media streaming. This allows your Samsung TV to view your computer's shared folders as external drives. The setup process is fairly simple, but it does require careful selection of the folders that will be available for viewing.
First, open Windows Settings, go to Network & Internet, then select Status and find the Media Streaming Settings option. In the window that opens, press the Power button and select your Samsung TV from the list of available devices. The system will then prompt you to select the folders whose contents will be shared with the TV.
☑️ Setting up DLNA on Windows
After completing the setup on your Samsung TV, you need to go to the signal sources menu (button Source or Input on the remote) and select "Connect to a media server" or "PC." The interface that opens will show you the folder structure of your computer. Navigation is done using the standard remote buttons, making this method convenient for older people or children.
⚠️ Note: The DLNA protocol does not support streaming Dolby Atmos or multichannel DTS-HD Master Audio in some configurations. If there is no sound when playing a movie, change the audio output in Windows settings to "Stereo" or use an external receiver.
Mirror your screen using Miracast and Connect to a Wireless Display
If your goal is not just to play a file, but to show a presentation, a website, or a game running on your computer, the best solution is technology MiracastIn Windows 10 and 11, this feature is built-in and is called "Wireless Display Connection." It allows you to fully mirror your PC monitor to your Samsung TV with minimal latency.
To get started, make sure the app is running on your Samsung TV. Screen Mirroring or the "Screen Casting" function (the name may vary depending on the model year). On modern models, simply navigate to the main menu, and the TV will automatically enter connection standby mode.
On your computer, press the key combination Win + KThe "Connection" panel will appear on the right, where your TV should be displayed. After selecting the device, the PC screen will turn off and the image will appear on the TV. This method is ideal for sharing content from browsers or apps that don't natively support Cast.
It's worth noting that using Miracast places a strain on the computer's graphics card and wireless module, as the video stream is encoded on the fly. This may result in reduced performance in demanding games or a slight reduction in image quality compared to direct file playback.
Using the Smart View app and Samsung Flow
Samsung has developed its own software tools to facilitate interaction between devices. The application Smart View (formerly known as PC Share Manager) not only allows you to share your screen but also manage your media library more flexibly than standard Windows tools. Available for download from the Microsoft Store, it provides a more stable connection to Samsung TVs.
After installing the program on your computer, launch it and follow the connection wizard's instructions. Smart View lets you create playlists, sort files by type, and even control playback from your smartphone if it's also connected to the system. This turns the PC-TV connection into a fully-fledged multimedia system.
An alternative could be a program Samsung Flow, which focuses more on syncing notifications and photos, but also features Smart View for image sharing. This is especially useful if you use a Samsung laptop or Galaxy tablet with your TV.
| Function | Smart View | Samsung Flow | Standard Miracast |
|---|---|---|---|
| Picture quality | High | Average | Depends on the signal |
| Latency | Low | Average | Low |
| Control from your phone | Yes | Yes | No |
| Difficulty of setup | Requires software installation | Requires software installation | Built into Windows |
Why might Smart View not see my TV?
The problem often stems from the Windows Firewall. When you first launch the program, it asks for permission to access the network. If you select "Public Network," access will be blocked. Change the network type to "Private" in the Wi-Fi settings or add Smart View to the firewall exceptions.
Broadcast via Google Chrome browser and Chromecast
Many modern Samsung TVs support the technology Google Cast (Chromecast built-in) or allow you to install a YouTube/Netflix app with casting functionality. However, if you're using a random video file from your computer, it's easiest to use a browser. Google ChromeIt has a built-in feature for casting tabs or the entire desktop to any Chromecast-enabled device.
To start, open the Chrome browser on your computer. Click the three dots in the upper-right corner of the menu and select "Cast." In the window that appears, select "Cast a file" (if available via extensions) or "Cast a desktop." Find your Samsung TV in the list.
This method is great because it's operating system-independent—it works equally well on Windows, macOS, and Linux. Furthermore, Chrome can stream system audio, which solves the problem of missing audio when showing presentations or videos from untrusted sources.
⚠️ Please note: When streaming via the Chrome browser, the load on your computer's processor increases significantly as it encodes the video stream in real time. Your laptop may become hot and the fan may become noisy. We recommend closing any unnecessary tabs and programs.
If your TV doesn't have built-in Chromecast support, you can use a physical Chromecast box connected to an HDMI port, but in the context of a Wi-Fi connection, we're specifically considering software emulation or built-in protocols.
Third-party players: VLC Media Player and Kodi
For users who find standard Windows tools limited, advanced media players are an excellent solution. VLC Media Player — is a "Swiss knife" in the world of video playback, which can not only play files, but also act as a DLNA server with advanced settings.
Launch VLC on your computer and go to "View" → "Playlist." On the left side of the window, find "Local Network" → "Universal Plug'n'Play." Here you can enable streaming. However, a more powerful option is creating a stream. In the "Media" menu, select "Stream," add a file, and select "UPnP/DLNA" as the output destination.
Another powerful tool is KodiBy installing Kodi on your computer and configuring it as a server, and installing the client app on your TV (via the Samsung app store) or using the built-in renderer, you can access a library with beautiful cover art, movie descriptions, and trailers. This turns a regular TV into a fully-fledged media center.
- 🎬 VLC supports almost all video codecs, eliminating "file not supported" errors.
- 📁 Kodi allows you to create a beautiful library with posters and actor descriptions.
- ⚙️ Both apps allow you to adjust buffering for weak networks.
Problem solving and quality optimization
Despite the simplicity of setup, users often encounter problems: video stutters, sound drops out, or the TV doesn't recognize the computer. Most often, the cause is an unstable Wi-Fi signal. If the router is located in another room or behind thick walls, the signal can weaken, which is critical for streaming video.
Another common issue is antivirus software or a firewall blocking incoming connections from the TV. In this case, you need to add exceptions for the "Media Server" or "Smart View" apps in the Windows security settings. It's also worth checking if your router has speed limits (QoS) for specific devices.
If you experience audio and video desynchronization (the audio track lags behind or precedes the image), try lowering the bitrate of the streaming file or switching the encoding method in the player settings. Sometimes, simply rebooting the router, which may be clogged with cache, helps.
⚠️ Note: Menu interfaces and item names may vary slightly depending on the Tizen OS version on your TV and the model year. If you don't find an exact match, look for synonyms in the "Network" or "General" sections.
In some cases, changing the DNS servers in the TV's network settings to public ones (for example, Google's 8.8.8.8) can help, which can speed up the response time when searching for devices on the local network.
Why can't my Samsung TV see my computer via Wi-Fi?
Most often, the issue is with the network type. Make sure the network in Windows is marked as "Private" and not "Public." Windows blocks device discovery on a public network. Also, check that SMB 1.0 is enabled in Windows Features, as older TV models may require this protocol.
Is it possible to stream 4K video over Wi-Fi without lag?
Yes, this is possible, but only if you're using a Wi-Fi 5 (AC) or Wi-Fi 6 (AX) router and connecting at 5 GHz. At 2.4 GHz, the 40-50 Mbps bandwidth may not be enough for large, high-bitrate 4K files.
Does the operation of other devices affect the quality of the broadcast?
Absolutely. If someone is downloading large files, playing online games, or having a video conference while watching a movie, the Wi-Fi channel may become overloaded. This will cause the video to buffer. For critical viewing, it's recommended to temporarily limit the bandwidth of other devices.
Do you need internet to stream video from PC to TV?
No, an internet connection is not required. Data transfer occurs within your local area network (LAN) between the router, computer, and TV. The main thing is that the devices are connected to the same router, even if the router itself is not connected to the global network.
