Modern technology allows you to completely eliminate unnecessary wires, turning your living room into a true multimedia center. Connecting a TV Samsung Connecting your computer via Wi-Fi opens up a wide range of possibilities, from watching movies on a big screen to sharing presentations and playing games. This solution is ideal for those who value aesthetics and order without the hassle of running HDMI cables across the room.
The process of synchronizing devices is based on wireless data transmission standards such as Miracast And DLNAThese protocols are built into the Windows 10 and 11 operating systems, as well as into the platform Tizen OS, which powers modern smart TVs from this South Korean brand. You don't need to be an engineer to set up the connection; just follow the logical steps outlined in this guide.
However, it's important to keep in mind that image quality and connection stability directly depend on your router's speed and location. If you plan to stream 4K video or play fast-paced games, Using the 5 GHz band is critical for a smooth, lag-free experience.Otherwise, the image may flicker or the sound may become out of sync.
Preparing equipment and network for stable operation
Before you begin setup, make sure all components of your home network are ready to use. The foundation of a wireless connection is the router, which must correctly distribute traffic between devices. Make sure both your computer and TV are connected to the same Wi-Fi network; otherwise, they simply won't see each other in the list of available devices.
Please note your PC's operating system version. To use the Projection feature on Windows 10 and 11, you need a Wi-Fi module that supports this technology. Wi-Fi DirectOn most modern laptops, this module is built in by default, while desktop PCs may require the installation of an external USB adapter.
⚠️ Note: If your router supports splitting the 2.4 GHz and 5 GHz bands with different network names (SSIDs), make sure both devices are connected to the 5 GHz network for maximum data transfer speed.
It's also worth checking that your TV's software is up to date. Manufacturers regularly release updates that improve the stability of network protocols and fix compatibility issues. Go to the menu Support → Software Update on the TV remote control to check for new versions.
Method 1: Wirelessly cast your screen via Miracast
The fastest and most versatile way to display an image is to use a built-in Windows function called "Projection." This method is based on the standard Miracast, which allows for real-time video and audio streaming with minimal latency. This option is ideal for sharing desktops, browsers, or games.
To start the process on a computer with Windows 10 or 11, you need to press a key combination Win + KThe "Connection" panel will open on the right, where the system will begin searching for available wireless displays. If the TV Samsung turned on and is on the same network, its name will appear in the list in a few seconds.
After selecting your TV, a prompt may appear on the screen asking if you want to allow the connection. Use your remote control to confirm the action by selecting "Allow." From this point on, your monitor's image will be mirrored to the big screen.
☑️ Check before connecting Miracast
It's important to note that this method creates a direct connection between your computer and your TV. This may temporarily reduce internet speeds on other devices if your router doesn't have sufficient bandwidth. This method is ideal for gaming, as input lag is minimal compared to other methods.
DLNA setup and media transfer
If your goal is not to duplicate your desktop, but to play video files, photos or music stored on your PC's hard drive, then the technology DLNA will be a more efficient solution. It allows the TV to view the computer as a network storage device and play content directly, without burdening the PC's processor with video stream encoding.
In Windows, this feature is called "Media Streaming." To enable it, go to "Network & Internet Settings," find the "Status" section, and select "Media Streaming Settings." In the window that opens, click "Turn on media streaming."
| Parameter | Description | Recommended value |
|---|---|---|
| Protocol | Connection type | DLNA / UPnP |
| Video quality | Stream bitrate | Original (uncompressed) |
| Formats | Supported codecs | MP4, MKV, AVI, MP3 |
| Net | Connection type | Private network |
After enabling the function, your TV should appear in the list of devices. SamsungMake sure its access status is set to "Allowed." Now, when you open any video file on your computer using a standard player or file explorer, you'll see the "Cast to device" icon, where you can select your TV.
Why doesn't the TV see folders with movies?
If your TV can't display certain files when streaming is enabled, there may be a codec issue. The built-in Samsung player may not support certain audio tracks (such as DTS) or containers. In this case, we recommend installing a third-party player, such as VLC, on your TV through an app store or using file transcoding.
Using the Samsung Smart View and SmartThings app
For deeper integration between your computer and TV, the manufacturer offers specialized software. The previously popular app Smart View for PC was discontinued, and its functions were partly transferred to standard Windows tools, and partly to the application SmartThingsHowever, older TV models may require installing separate software from the official website.
The modern approach involves the use of an ecosystem SmartThingsBy installing the app of the same name on your PC (available in the Microsoft Store) or using the web version, you gain access to content management. This is especially convenient for laptop users who want to quickly share a photo album or presentation with colleagues.
The app pairs by searching for devices on the local network. Once the TV is detected, you must enter the PIN displayed on the TV screen. This ensures protection from unauthorized access, preventing third-party devices from connecting to your display.
⚠️ Note: The interface and feature names in Samsung apps may vary depending on the TV's year of manufacture and Tizen firmware version. If you can't find the option you need, check the latest user manual for your specific model on the official support portal.
Alternative methods: Steam Link and third-party software
Gamers will appreciate the opportunity to use the platform Steam LinkThis app, available in the Samsung app store, lets you stream games from your PC directly to your TV, using it as a monitor. Control is via a gamepad connected to the computer or TV via Bluetooth.
Steam Link requires Steam to be running on your computer and the "Remote Play" feature enabled. Image quality in this mode can be flexibly adjusted, choosing between response speed and visual quality. With a good Wi-Fi connection, latency is virtually imperceptible.
Another powerful tool is the program PlexIt turns your computer into a full-fledged media server. Unlike simple DLNA, Plex automatically downloads cover art, movie descriptions, and sorts content by genre, creating a beautiful interface on your TV.
Diagnosing problems and improving signal quality
Even with proper setup, users may encounter problems: the image may appear blocky, the audio may lag behind the video, or the connection may constantly drop. Most often, this is due to radio congestion or a weak signal.
Use Windows' built-in diagnostic tools. In the command prompt (run as administrator), enter the command netsh wlan show interfacesPay attention to the "Signal Quality" parameter. If it's below 70-80%, stable operation is not expected.
- 📶 Move the router: Make sure there are no thick concrete walls or metal structures between the router and the TV that will shield the signal.
- 🔄 Change Wi-Fi channel: Download a Wi-Fi analyzer app to your smartphone and find the least congested channel, then manually enter it into your router settings.
- 💻 Update your drivers: Visit the network adapter manufacturer's website and install the latest drivers for your Wi-Fi module model.
If the problem persists, try resetting the network settings on your TV. Go to Settings → General → Network → Network ResetThis action will delete all saved passwords and settings, but it often helps to resolve software glitches in the device's network stack.
Frequently Asked Questions (FAQ)
Is it possible to connect a computer to a Samsung TV without Wi-Fi?
