Hardware and network requirements
To successfully implement wireless data transfer, your laptop and TV must meet certain technical requirements. First and foremost, both devices must support the standard. Wi-Fi Direct or technology MiracastMost modern Samsung models released after 2015 already have built-in support for these protocols.
It's crucial that both devices are on the same local network. The router must be stable, preferably at 5 GHz to transmit high-resolution video without artifacts. If you're using a guest network or isolated VLANs, the connection may fail due to security restrictions.
⚠️ Important: Make sure that the AP Isolation feature is not enabled on your router, which prevents devices within the network from seeing each other.
Also check the driver version of your wireless adapter. Outdated network card software often causes an unstable connection or the TV to not appear in the list of available devices. Updating the drivers from the laptop manufacturer's official website often resolves the issue.

☑️ Preparing your TV for connection
Using the Connect feature in Windows 10
The fastest way to mirror an image is to use the operating system's native feature. In Windows 10, this tool is integrated into the Action Center and Project Bar. It allows you to mirror your screen or extend your desktop to a TV without installing any additional software.
To launch, press the key combination Win + K on the keyboard. The "Connect" sidebar will appear on the right. The system will begin searching for available wireless displays. If the TV is configured correctly, you will see its name in the list.
Once you select a device, the pairing process will begin. A connection permission request may appear on the TV screen—confirm it with the remote. The image from your laptop will appear on the big screen. You can change the operating mode through the menu. Projection (Repeat, Extend, Second Screen Only).
⚠️ Please note: When using the "Extend" mode, the mouse cursor may behave unpredictably if the screen resolutions of your laptop and TV are very different.

Comparing Connection Methods: Miracast vs. DLNA
Users often confuse content transfer technologies, although they solve different problems. Miracast is used for full screen broadcasting (mirroring), while DLNA It is designed for streaming specific files (video, photos, music) through a media server.
When using DLNA, the TV acts as a renderer and the laptop acts as a server. This allows you to control playback with the remote, pause, and rewind videos without having to look at the laptop. However, you can't stream your desktop or browser via DLNA.
| Characteristic | Miracast (Screen Casting) | DLNA (Streaming Media) |
|---|---|---|
| Purpose | Complete duplication of the Windows interface | Playing files (photos, videos) |
| Control | From a laptop (mouse/keyboard) | From the TV remote or app |
| Delay | Minimal, but possible | None (buffering) |
| Background mode | You can't work on a PC (everything is visible) | You can work on your PC in parallel |
The choice of method depends on your goals. For games or presentations, only the first option is suitable. For viewing downloaded movies at high bitrates, it's better to use the DLNA capabilities built into the standard Windows player or app. Samsung Smart View.
Broadcasting via Microsoft Edge browser

Open the page with the video or presentation, click on the three dots in the upper right corner of the menu and select the item Stream to device (Cast to device). Select your Samsung TV from the list. This will allow you to cast only the contents of the tab, keeping other windows private.
This method is especially effective for streaming services, as the TV handles some of the video processing, reducing the load on the laptop's processor. Image quality is often higher, and latency is lower compared to full screen mirroring.
Troubleshooting and diagnostics
Despite the simplicity of setup, users may encounter difficulties. Most often, the problem stems from different networks: the laptop is connected to a cable (LAN) and the TV via Wi-Fi, or they are connected to different frequency bands (2.4 GHz and 5 GHz), which the router isolates from each other.
If searching for devices doesn't produce any results, try rebooting your router. This is a classic but effective step that flushes the DNS cache and updates routing tables. It's also worth checking whether your antivirus or Windows Firewall is blocking device detection on your local network.
If artifacts or audio and video desync occur, reduce the output resolution on your laptop or the frame rate. A congested Wi-Fi channel may also be the cause: turn off other devices that are actively consuming bandwidth.
⚠️ Please note: Samsung TV interfaces are updated regularly. The layout of menu items may differ from those described, so please check the manufacturer's official website for the latest instructions.
