How to connect a PC to a Samsung TV via WiFi

Modern televisions Samsung They have become powerful multimedia centers that easily integrate into a home network. Wirelessly connecting a personal computer to such a screen provides access to a vast array of content without the need for unnecessary HDMI cables. This solution is ideal for viewing movies, photos, and even presentations in high definition.

There are several proven methods for organizing communication between Windows PC and Smart TVs, each with its own unique features. The specific method you choose depends on your TV model, your computer's operating system, and the type of content you're streaming. In this article, we'll cover all the current setup options so you can enjoy your media library on the big screen.

The main advantage of a wireless connection is the freedom to position your equipment. You don't need to run long wires across the room or move your laptop right next to the TV. A stable signal is all you need. Wi-Fi networksto broadcast images or media files in any convenient position.

Hardware and network requirements

Before starting setup, you need to ensure that all components of your system are ready to communicate. A fundamental requirement is that both devices are on the same local network. This means that both the computer and TV must be connected to the same router.

If you're using a wired connection for one device (for example, a PC connected via LAN cable and a TV via WiFi), make sure the router is correctly assigning IP addresses to both devices. In rare cases, the router's security settings may isolate wireless devices from wired ones, which will require checking the settings. AP Isolation in the router's admin panel.

You should also consider your bandwidth. To transmit video in the resolution 4K or Full HD A stable data transfer rate is required to avoid delays and compression artifacts. A weak signal can lead to audio and video desynchronization.

• 📺 Samsung Smart TV (J, K, M, N, Q, LS series and newer).
• 💻 A computer or laptop running Windows 10 or 11 with a WiFi module.
• 📶 A router that supports 802.11n/ac/ax standards (preferably dual-band 5 GHz).
• 🔌 Up-to-date software on both devices.

⚠️ Note: If your router broadcasts two networks (2.4 GHz and 5 GHz) with different names, be sure to connect both devices to the same frequency to ensure visibility.

Pay special attention to the wireless adapter drivers on your computer. Outdated software may not work correctly with media device discovery protocols. It's recommended to open the Device Manager and check the network adapter's status.

DLNA Method: Streaming Media Files

The most common way to transfer photos, videos and music is technology DLNAIt allows you to stream content from your computer's hard drive to your TV screen, using the TV itself as a remote control. This method doesn't require duplicating your entire desktop.

The standard Windows "Media Streaming" feature is used to establish a connection. You don't need to install any third-party software, as all the necessary components are already built into the operating system. The setup process takes just a few minutes.

First, you need to enable file sharing. Open Windows Settings, go to Network & Internet, and find Sharing options. Turn on network discovery and file and printer sharing for the current network profile.

1. Open "Media Streaming Settings" via Windows Search.
2. Click the "Turn on media streaming" button.
3. Find your TV in the list of found devices. Samsung.
4. Set your TV status to "Allowed".

After completing the setup, launch any video player on your computer (for example, the standard “Movies and TV” or VLC Media Player). Open the file you want to watch, right-click it, and select "Cast to device." Your TV will appear in the list.

This method is convenient because playback controls (pause, rewind, volume) are completely transferred to the TV remote control. The computer, in this case, merely acts as a data storage server.

Wireless monitor via Miracast

If your goal is to completely duplicate your computer screen on your TV, the technology Miracast (implemented in Windows as "Wireless Display Connection") is the optimal solution. It creates a direct connection between devices, transmitting a real-time video stream.

Unlike DLNA, it streams the entire operating system interface rather than a specific file. This allows you to launch a browser, show presentations, or play games without being tied to the PC monitor's diagonal size. The image on the TV will update in sync with your mouse movements.

To start working, press the button on your Samsung TV remote control. Home or Smart HubIn the Source menu, select "Connect to a mobile device" or "Screen Mirroring." On some newer series models, this option may be called "Wireless Casting."

On your computer, press the key combination Win + KThe "Connection" panel will appear on the right, where the system will begin searching for available displays. Select your TV from the list.

You may see a connection permission prompt on the TV screen. Use your remote to press "Allow" or enter the PIN if displayed. Once paired, the Windows desktop will appear on the big screen.

It's important to understand that using a wireless monitor significantly increases the load on the processor and graphics card. The system encodes the video stream on the fly, which can lead to reduced performance in demanding games or 3D modeling programs.

What to do if the mouse cursor is twitching?

If you notice cursor lag or image stuttering, try lowering the TV's output resolution or moving your computer closer to the router. Switching to a 5 GHz channel may also help.

Using the SmartThings app

Samsung has developed its own application SmartThings, which serves as a universal smart home control center. It also allows you to conveniently connect your PC to your TV, especially if standard Windows tools are unstable.

The app is available in the Microsoft Store for Windows 10 and 11. After installation and authorization with your Samsung account (which must match the account on your TV), the program will automatically find compatible devices on the network.

SmartThings' functionality not only allows you to mirror your screen but also use your computer as a remote control. You can control the volume, change channels (if a receiver is connected), or launch apps on your TV directly from the program window on your PC.

To start screencasting in the app, select your TV and click the "Cast Screen" button (or the monitor icon). The system will prompt you to select a mode: screen mirroring or extended workspace.

⚠️ Note: SmartThings View may not be available on some older Samsung TV models (manufactured before 2018). In this case, use the built-in Windows tools.

The advantage of this method is the ability to control multiple devices simultaneously. If you have a Samsung soundbar or smart lamps, you can coordinate their operation with your TV through a single interface.

Broadcast via browser and AirPlay 2

Computer owners Mac or users who prefer browser broadcasting can take advantage of protocol support AirPlay 2Modern Samsung TVs (since 2019) have built-in support for this Apple technology.

For macOS users, the process is extremely simple: simply click the "Screen Mirroring" icon in the control panel and select your Samsung TV. No additional drivers are required, as the protocol is natively built into the system.

Windows users can also stream browser content Google Chrome or Microsoft EdgeOpen a video on a website (e.g., YouTube), right-click on the video, and select "Cast." Your TV should appear in the list of devices.

This method is convenient because it doesn't require extensive network configuration. The browser automatically finds Chromecast or AirPlay devices on the local network. However, the quality of the streaming depends entirely on the browser's performance and internet connection speed.

• 🍏 AirPlay 2 support makes it easy to connect Apple devices.
• 🌐 Browser tab streaming doesn't require any additional software.
• 🎞️ Ideal for watching online videos from websites.
• ⚠️ Not suitable for gaming due to high input lag.

It's worth noting that when streaming through a browser, video encoding is performed programmatically, which can lead to increased RAM consumption. If the video is lagging, try closing unnecessary tabs.

Troubleshooting and Common Mistakes

Despite the simplicity of the technology, users often encounter a situation where the computer "doesn't see" the TV. The most common cause is Windows firewall or antivirus settings that block incoming connections to media services.

Try temporarily disabling your firewall to test. If the connection is established after this, you'll need to add an exception to the rules for the Media Server service or the SmartThings app. Also, make sure the network type in Windows is set to "Private" and not "Public."

Another common problem is audio and video desynchronization. This often occurs when neighboring routers overload the WiFi channel. In this case, switching to a less congested channel in the router settings or switching to the 5 GHz frequency will help.

If your TV periodically turns off while you're watching, check the power saving settings on your PC's network adapter. Windows may try to conserve power by disabling the WiFi module during periods of low activity, which disrupts the data flow.

In some cases, resetting the device list on the TV itself helps. Go to the mobile device connection settings on the TV and remove all previously connected PCs, then try pairing again.

Comparison of connection methods

The best method depends on your current needs. If you simply need to share photos with family, DLNA or SmartThings will do. For gaming or document editing, Miracast, which offers minimal latency, is best.

To watch online movies from a laptop, the most convenient way is to use the built-in "Stream" function in your browser or the YouTube app on your Smart TV, launching the video from your computer using a pairing code.

Remember that wireless technologies are constantly evolving. Update your TV's firmware through the menu. Support → Software Updateto receive new codecs and improved connection stability.

Why isn't my Samsung TV showing up in the list of available devices?

Most likely, the devices are on different networks (for example, one on a guest network and the other on the main network) or client isolation is enabled on the router. Also, check if your antivirus software is blocking network discovery.

Is it possible to play PC games via WiFi on TV?

Technically possible via Miracast, but input lag will be noticeable over a wireless connection. A wired HDMI connection is recommended for shooters and fast-paced games. For turn-based strategy or card games, WiFi is fine.

How to improve picture quality during wireless broadcasting?

Move closer to your router, use the 5 GHz band, close programs downloading files in the background, and make sure your TV's picture mode is set to "Movie" or "Dynamic" depending on the content.

Do you need internet access to connect your PC to your TV via WiFi?

No, internet access is not required. A local network (router) is sufficient, even without access to the global network. DLNA and Miracast protocols work within the local network between devices.
