You won't need to buy additional adapters or complex routers if both devices are on the same network. The main thing is to ensure a stable signal and properly configure security settings.
In this article, we'll walk you through all setup steps, address potential errors, and offer solutions for various usage scenarios. You'll learn how to control content from your computer keyboard while displaying images on a 65-inch or larger display. Follow the instructions to enjoy high-quality content without lag.
Network requirements and equipment preparation
Before you begin setup, make sure your router supports the standard. 802.11n or higher (ac, ax). Older router models may not be able to handle 4K video streaming, resulting in constant buffering and reduced image quality. Dual-band routers operating at 5 GHz are recommended.
Both devices are a laptop and a TV Samsung — must be connected to the same Wi-Fi network. If you have guest access or client isolation configured on your router, the devices may not be able to see each other. Check your router settings to allow local communication between devices.
It's also worth updating your TV's software to the latest version. Manufacturers regularly release patches that improve the module's stability. Wi-Fi Direct and fixing security vulnerabilities. Old firmware may not support new codecs or encryption protocols used in Windows 10/11.
⚠️ Attention: If your router broadcasts both 2.4 GHz and 5 GHz under the same SSID, try temporarily separating them. Your laptop and TV should connect to the same frequency, preferably 5 GHz, to ensure maximum throughput.
Check your laptop's battery or connect it to a power source. Actively streaming video over Wi-Fi consumes significant power, and the device may enter power-saving mode, disconnecting at the most inopportune moment.
Setting up a Samsung TV to receive a signal
The first step is to activate the external signal reception function on the TV itself. In most modern models Samsung This option is enabled by default, but requires confirmation the first time you connect a new device. Access the settings menu using the remote control.
Go to the section Settings → General → Device Menu → Connection MenuHere, you need to enable the "Connection Notification" or "External Connection Manager" option. This will allow the TV to automatically respond to requests from the laptop.
Older models may require manual launch of the application. Screen MirroringFind it in the list of apps on the Smart Hub main panel. Once launched, the TV will go into standby mode and be discoverable by other devices within range.
☑️ Check TV readiness
It is important to note that some models support the function Auto Power On from a mobile device. If you plan to use the connection frequently, enable this option so that the TV turns on automatically when you try to stream from your laptop.
Mirror your laptop's screen using the Connect to Wireless Display feature.
This is the fastest way to display the entire Windows desktop on your TV screen. Technology Miracast Allows you to clone your screen or extend your desktop without using a router, working directly via Wi-Fi Direct.
On your laptop keyboard, press the key combination Win + KThe "Connect" panel will open on the right. Your TV should appear in the list of available devices. SamsungClick on it to start pairing.
A connection permission request may appear on the TV screen. Use the remote control to select "Accept" or enter the PIN if displayed. The laptop's image will then appear on the big screen.
If the search doesn't return any results, make sure that discovery is enabled in Windows settings. Go to Settings → System → Project to this PC and set the value to "Always disabled" only if you do not want other devices to connect to the laptop, but for the outgoing connection this is not critical.
What should I do if the connection keeps dropping?
If the connection is unstable, try lowering the output resolution on your laptop to 1080p or 720p. Disabling your antivirus or firewall while testing may also help, as they can block Miracast ports.
Using DLNA to play media files
If your goal is not to broadcast your desktop, but simply to watch a movie or a photo album, the technology DLNA would be a better choice. It provides more stable video quality since it doesn't require real-time image encoding, but rather transfers the finished file.
In Windows 10 and 11, this feature is built into the standard File Explorer. Find the video file you want, right-click it, and select Cast to device → Samsung TVPlayback will start automatically through the TV's built-in player.
For more advanced controls, use the built-in Media Viewer app or third-party programs like Home Media ServerThey allow you to create libraries, add covers and descriptions to films, turning your TV into a full-fledged media system.
| Parameter | Miracast (Broadcast) | DLNA (Media) |
|---|---|---|
| Transmission type | Image stream (screencasting) | File transfer |
| CPU load | High (video encoding) | Low |
| Quality | Depends on Wi-Fi signal | Original (lossless) |
| Control | From a laptop | From a TV remote or laptop |
The advantage of DLNA is that you can continue working on your laptop while watching a movie on your TV. In mirroring mode, any notifications or open windows will be visible on the big screen, which isn't always convenient.
Samsung SmartThings app for advanced control
For ecosystem owners Samsung the official app would be a great solution SmartThings, available in the Microsoft Store. It provides deeper integration, allowing you to not only mirror your screen but also control your TV settings.
After installing the app and signing in to your Samsung Account, it will automatically search for compatible devices on the network. Select your TV from the list and click the "Cast" button in the app interface. This is an alternative if the standard Windows tools don't work correctly.

The app features a "Game Mode" feature that optimizes input lag when playing laptop games on a TV. This is critical for fast-paced games where every millisecond matters.
Solution and troubleshooting
The most common issue is that the TV doesn't appear in the list of available devices. In this case, try rebooting the Wi-Fi module on both devices. Sometimes, completely unplugging the TV for 10-15 seconds to clear the network cache helps.
If you see a picture but no sound, check your Windows playback settings. Click the speaker icon in the system tray, select the output device, and select your TV. SamsungThe sound should switch from the laptop speakers to the TV audio system.
Image lag and stuttering are often caused by Wi-Fi congestion. If a microwave is running nearby or neighboring routers are interfering, connection quality will degrade. In this case, Using the 5 GHz Wi-Fi band is a critical decision, as it is less congested and has greater throughput.
Check your laptop's wireless adapter drivers. Outdated drivers may not support the latest WPA3 encryption standards, which may be enabled on newer routers. Update them through Device Manager or the manufacturer's website.
Questions and Answers (FAQ)
Is it possible to connect a laptop to a Samsung TV without a router?
Yes, using Wi-Fi Direct technology. In this mode, the TV automatically creates an access point to which the laptop connects. However, the laptop's internet connection will not work at this point; only local image streaming will be available.
Why does the video stutter or lag when streaming?
Most likely, your Wi-Fi channel isn't providing enough bandwidth. Try moving the router closer to your devices, disabling downloads on other devices, or reducing the video quality in your player from 4K to 1080p.
Do all laptops support connection to Samsung TV?
Almost all modern laptops running Windows 8.1 and above support Miracast. Older models or macOS may not support it natively, so you'll need to install third-party software.
How do I turn off screen sharing?
Press the combination Win + K and select "Disconnect", or simply press the "Return" or "Exit" button on your TV remote to disconnect from the TV side.
Does connecting a TV affect internet speed?
When using DLNA, speed isn't affected because files are retrieved from the local network. When using screen sharing (Miracast), part of the bandwidth is used to transmit the video stream, which may slightly reduce download speeds on other devices.
