- 🔌 On new Tizen OS models, the function is often integrated into the main standby screen.
- 🌐 Make sure that the "Invisible" mode (if you need a hidden connection) or the standard visible mode is enabled in the network settings.
Once the mode is activated, the TV will begin searching for available devices. If the connection hasn't been established within a few minutes, try restarting the TV by completely unplugging it for 30 seconds. This will help clear temporary network module errors.
☑️ Preparing your TV for connection
Starting a broadcast through the Windows 10 Action Center
The fastest way to display an image on the screen Samsung - using built-in tools Windows 10The operating system has native support for the protocol. Miracast, eliminating the need to install third-party software. This method ensures minimal signal latency.
Press the key combination Win + K on your laptop's keyboard. The "Connection" panel will open on the right. The system will begin scanning for available wireless displays. Your TV should appear in the list. Samsung with the corresponding model name.
Click on the TV's name. A confirmation message may appear on the TV screen. Use the remote control to select Allow or Accept. After this, the desktop image will be duplicated on the large screen.

- 🖥️ Recurring - the same picture on both screens.
- ↔️ Expand — the TV becomes a second monitor.
- 📺 Second screen only — the laptop goes out, only the TV works.
Using the Connect app and finding devices
In some cases, automatic search via the notification panel may not work right away. In this case, you should use the classic Windows settings menu. Right-click on the desktop and select Screen parameters or go through Start → Settings → System.
Scroll down the menu to the section Multiple displays. There should be a link called "Connect to a wireless display." Clicking it will open a search window similar to the one in the panel. ConnectHere you can see more detailed information about the search status.

| Problem | Possible cause | Solution |
|---|---|---|
| The TV is not visible | Different Wi-Fi networks | Check the router's SSID |
| Black screen | Blocked by antivirus | Add firewall exceptions |
| Low resolution | Weak signal | Move closer to the router |
| No sound | No output device selected | Select TV in the sound settings |
Alternative methods: DLNA and browser
If live screen broadcasting (mirroring) is causing a load on the system or is unstable, you can use the technology DLNAThis method doesn't duplicate your desktop, but allows you to stream specific media files (videos, photos, music) from your laptop to your TV.
To do this, open Windows Explorer, find the video file you want, right-click it, and select Transfer to device and select your TV SamsungThe standard player will launch, controlling playback on the TV.
Another option is to use the built-in browser Google Chrome or Microsoft EdgeOpen the browser menu (three dots in the corner), select Broadcast (Cast). You can cast a browser tab or the entire screen. This is convenient for watching online videos from sites that don't have a Smart TV app.

Troubleshooting and quality optimization
The most common problem is audio and video desynchronization or intermittent image flickering. This almost always indicates bandwidth issues. Miracast very sensitive to interference.
Try switching your router to a channel with less traffic or, if possible, use a band 5 GHzIt provides higher data transfer rates, which is critical for streaming video. The 2.4 GHz frequency is often congested by neighboring networks and household appliances.
The secret to a stable connection
If you have a dual-band router but it combines networks under one name, try temporarily separating them (giving them different names, for example, Home_2G and Home_5G) and forcing your laptop and TV to connect to the 5 GHz network. This often solves the "dropout" issue.
It's also worth checking if there are any background downloads (torrents, game updates) running on your laptop, which could be consuming your bandwidth. Close any unnecessary apps that are consuming bandwidth. If lag persists, try lowering the display resolution in the settings. Win + P → Advanced display options.
Frequently Asked Questions (FAQ)
Is it possible to display an image if the laptop does not have a Wi-Fi module?
Without a built-in or external USB Wi-Fi adapter, wireless image transmission is impossible. Miracast and DLNA protocols require a wireless module. In this case, a wired connection via HDMI cable is the only option.
Why is there no sound when connected, although there is a picture?
Most likely, your laptop speakers are still set as the audio output device. Click the volume icon in the Windows system tray, select the current playback device, and find your TV in the list. Samsung (often referred to as Intel WiDi or TV model).
Does connecting other devices to Wi-Fi affect picture quality?
Yes, it does. Since the connection channel is shared, active file downloads by other users or smart home functionality can create latency (ping). For an ideal picture, it's best to have a clear connection while viewing heavy content.
Does my old Samsung TV support this feature?
Screen Mirroring (Miracast) has been available on Samsung TVs since the ES series (2012-2013) and newer. Older models (D-series and earlier) do not have a built-in Miracast receiver and require a separate set-top box (such as a Chromecast or Android TV box).
