Wireless connectivity eliminates the need to run long HDMI cables across the room. Data transmission technologies in the ecosystem Samsung Allows you to establish a connection in minutes. It's important to keep in mind that image quality directly depends on the stability of the wireless signal.
In this article, we'll cover all the current connection methods, built-in Windows operating system features, and manufacturer-specific apps. You'll learn how to set up wireless display and understand DLNA protocols. This will open up new possibilities for home theater and work.
Network requirements and preparation steps
Before starting setup, make sure both devices have the same connection conditions. The computer and TV must be connected to the same wireless network. If your router broadcasts signals on both 2.4 GHz and 5 GHz frequencies, it's best to have both devices use the same frequency for best compatibility.
Make sure Smart Hub is enabled on your Samsung TV and network access is enabled. Some models may require separate permission to accept external connections in the security settings. Check that the software TV updated to the latest version available from the manufacturer.
Certain requirements are also required for a PC. If you're using Windows 10 or 11, the operating system's built-in features allow you to work without installing additional software. However, your wireless adapter drivers must be up-to-date.
- 📶 Make sure your Wi-Fi router provides a stable signal without frequent interruptions.
- 📺 Make sure your Samsung TV is on the same subnet as your computer.
- 💻 The Wi-Fi module must be enabled on the PC (even if connected via a wired connection to the router).
- 🔒 Disable the "Guest Network" mode on your router if it is blocking communication between devices.
⚠️ Note: If your router uses AP Isolation, devices will not see each other. This feature must be disabled in the router settings.
Screencasting using built-in Windows tools
The fastest way to connect a computer and a Samsung TV via Wi-Fi is using Miracast technology. This feature is built-in in Windows 10 and 11 operating systems and doesn't require any third-party software. In this case, the TV acts as a wireless monitor.
To get started, press the key combination Win + K on your computer keyboard. The "Connection" panel will open on the right, where the system will search for available devices. If your Samsung TV is online and ready to pair, its name will appear in the list.

☑️ Check before connection
It's worth noting that when transmitting high-definition video, a slight delay in the cursor or audio may be observed. This is normal for wireless protocols. When viewing static content or working with documents, this is completely unnoticeable.
Using the SmartThings app for Samsung
Samsung has developed its own platform for managing smart appliances. The application SmartThings Miracast not only allows you to control household appliances but also mirror your screen. This is a more advanced method than standard Miracast, as it offers additional control features.
To use this method, you need to install the app from the Microsoft Store on your Windows computer. The app must also be installed and running on your Samsung TV. SmartThings (On newer models, it's built into the system.) After logging in with the same Samsung Account, the devices sync.
The program's interface allows you to choose exactly what content to broadcast: the entire screen, a specific application window, or just media files. This is convenient if you want to show a presentation but don't want to share personal messages or open browser tabs.
- 📲 Download the SmartThings app for PC from the official store.
- 🔑 Sign in to your Samsung account on both devices.
- 📺 Select your TV from the list of available devices in the app.

| Parameter | Miracast (Broadcast) | DLNA (Media) |
|---|---|---|
| PC load | High (encodes video) | Minimal (only transmits stream) |
| Picture quality | Depends on the signal | Original (uncompressed) |
| Control | Full screen control | Play file only |
| Background tasks | Impossible (screen busy) | Any action is possible |
What should I do if the file doesn't play?
If your TV doesn't recognize the file format via DLNA, it may not support the codec. In this case, use screen mirroring (Miracast), where your computer will handle the decoding, or install a third-party player like VLC on your TV.
Solving common connection problems
Despite the simplicity of setup, users sometimes encounter difficulties. Often, the problem lies in Windows Firewall settings, which can block incoming connections from the TV. Check if network discovery is enabled in the "Private Network" profile.
An outdated Wi-Fi adapter driver could also be the cause of the crash. Go to Device Manager, find your wireless module, and try updating the driver or uninstalling the device and then rebooting to automatically reinstall it.
If your Samsung TV no longer appears in the list of available devices, try rebooting your router. Sometimes a temporary glitch in the router's ARP table prevents devices from being visible to each other.
