Modern technology allows you to transform your living room into a true cinema without the hassle of fiddling with cables. If you're wondering how to watch a movie from your computer on your Samsung TV using Wi-Fi, you've come to the right place. A wireless connection frees up space and gives you freedom of movement, allowing you to control content directly from your laptop or tablet keyboard.
There are several proven methods for achieving this goal, each with its own unique features. The method you choose depends on your operating system, TV model, and video file format. In this article, we'll cover all the current options in detail so you can enjoy your favorite movies on the big screen without lag or loss of quality.
Preparing equipment and network
Before you start the setup, you need to make sure that both devices are in the same connection conditions. The key requirement The key is to have the computer and TV on the same local network. This means they must be connected to the same router, either via cable or wirelessly.
If you're using a dual-band router, make sure both devices are connected to the same frequency—either 2.4 GHz or 5 GHz. While modern routers can combine networks, sometimes separate frequencies can prevent devices from discovering each other. Check that Wi-Fi is enabled on your TV. Samsung, by going to the network settings menu.
⚠️ Note: Using a guest Wi-Fi network often blocks data exchange between devices. Make sure you're connected to your main home network, which allows communication between clients.
It's also worth updating your TV's software to the latest version. Manufacturers regularly release patches that improve the stability of media transfer protocols. To do this, go to Settings → Support → Software Update and run the scan.
Using Miracast (Screen Mirroring)
The fastest way to stream content is using Miracast technology, often referred to as Screen Mirroring or Smart View in the Samsung ecosystem. This method allows you to completely mirror your computer screen on your TV, making it ideal not only for movies but also for presentations or games.
This feature is built into Windows 10 and 11 by default. You don't need to install any additional software. Just press a key combination. Win + Kto open the connection panel. Your TV should appear in the list of available devices. Samsung.
After selecting the device, a connection permission prompt may appear on the TV screen. Accept it using the remote control. The monitor's image will now be mirrored to the big screen. Please note that with this method permission and the frame rate can be adapted to the capabilities of the wireless channel.
☑️ Check before connecting Miracast
It's worth keeping in mind that when transmitting high-resolution video (4K HDR) over the air, slight cursor lag or image artifacts are possible if the signal is unstable. This can be critical for viewing dynamic scenes in movies, so this method is better suited for static content or Full HD video.
Broadcast via built-in browser and Smart View
If you want to show a specific online video rather than your entire desktop, you can use your browser's built-in capabilities. Many modern browsers, such as Google Chrome or Microsoft Edge, have a built-in Cast feature that allows you to send a tab or the entire screen to a compatible TV.
To do this, open the video in your browser, click on the menu (three dots) and select "Broadcast" or "Cast". The system will find your Samsung TV, and you can choose what to broadcast: just the video tab or the entire screen. This often produces a smoother picture than mirroring the entire desktop.
Why might video slow down when streaming through a browser?
Slowdowns are often caused by the browser's insufficient processing power to encode the video stream in real time or by other devices congesting the wireless channel. Try closing unnecessary tabs or lowering the video quality in the player.
An alternative option is to use an app Smart View for Windows, if available for your model, or the Samsung app on your smartphone, which will then stream content to your TV, with your PC acting as a server. However, the direct browser method is often the most stable for online cinemas.
Setting up a DLNA server for local files
DLNA technology is ideal for watching movies stored on your computer's hard drive. It allows the TV to view folders containing media files on your PC as external drives. In Windows, this feature is implemented through "Media Streaming."
To enable streaming, open the Control Panel, go to Network and Internet, and find Media Streaming Settings. Click Turn on Media Streaming. In the window that opens, you'll see a list of devices on the network. Find yours. Samsung TV and make sure that the "Allowed" box is checked next to it.
| Parameter | Description | Recommended value |
|---|---|---|
| Protocol | Data connection type | DLNA / UPnP |
| Video formats | Supported codecs | MP4, MKV, AVI |
| Net | Windows network profile type | Private network |
| Firewall | Rule for media server | Allow |
After setting up, press the button on the TV remote control Source or "Home" and select "Media" or "Connect to PC." You'll see your computer's name. Once logged in, you'll have access to the default folders: "Videos," "Music," and "Pictures." If the movie you want isn't in the default folders, you can add it through the Windows streaming settings.
The advantage of DLNA is that playback controls (pause, rewind) are controlled using the TV remote, allowing the computer to be used for other tasks or even the monitor to be turned off. Image quality is also maximized, as the file is transmitted in its original format without re-encoding.

Third-party programs for advanced features
Windows' built-in tools are great, but sometimes their functionality isn't enough. Third-party media servers allow you to stream virtually any video format, add subtitles on the fly, and create a beautiful library with posters. The leader in this area is Plex.
Install the Plex server on your computer and the client app from the Samsung Apps store on your TV. After registering with a unified account, your PC will appear in the list of sources. Plex will automatically download movie covers, descriptions, and cast members, transforming the file list into a fully functional cinematic interface.
Other popular alternatives include Universal Media Server And ServiioThese can be useful if the TV's built-in player doesn't support a specific audio codec or container format. In this case, the server will transcode the stream in real time so the TV can play it.
⚠️ Please note: The transcoding process (on-the-fly encoding) places a significant load on your computer's processor. Heavy 4K HDR videos may require powerful hardware, otherwise the video will stutter.
Using third-party software also allows you to access your files not only within your home but also over the internet, turning your home PC into a personal cloud service. However, for a home Wi-Fi network, basic DLNA or Miracast settings are sufficient.
Troubleshooting connection issues
Despite the apparent simplicity, users often encounter problems with their TV not being detected by their computer. One of the most common causes is the incorrect network type in Windows. If the system considers your network "Public," it blocks device discovery. Change the network profile to "Private" in the Wi-Fi settings.
Another important point is antivirus software and firewalls. They can block ports required for media streaming. Try temporarily disabling protection or adding your media application to the exception list. Also, make sure that services SSDP Discovery And Media Server launched in Windows (you can check it through services.msc).
If the image is transmitted, but the sound is only coming from the computer, check the playback device settings. Click the speaker icon in the Windows tray, select the audio output device, and find your device in the list. Samsung TVSwitching will take a couple of seconds.
If all else fails, try rebooting your router. Sometimes the DHCP server cache becomes full, preventing new connections from establishing correctly. Simply powering off the router for 10 seconds often works wonders.
Comparison of methods and final recommendations
The method you choose depends on your priorities. If you just need to show photos or a presentation, use Miracast. For watching downloaded movies in high quality without putting a strain on your system, DLNA is a better choice. And if you want a beautiful library, install Plex.
Keep in mind that Wi-Fi speed directly impacts image quality. For 4K content, it's recommended to use the standard. Wi-Fi 5 (AC) or Wi-Fi 6 (AX)Older routers may not be able to handle large files, and the video will buffer.
Always try to place your router within direct line of sight or minimize the number of walls between it and your TV. Metal structures and mirrors can also block the signal, causing connection interruptions while watching.
Why doesn't my Samsung TV see my laptop?
Most often, the problem lies in the Windows Firewall settings or network type. Make sure that AP Isolation isn't enabled in your router settings, which prevents devices from seeing each other.
Is it possible to stream 4K video over Wi-Fi without lag?
Yes, it's possible, but it requires a router that supports 5 GHz and the AC/AX Wi-Fi standard. The 2.4 GHz band has a limited bandwidth and won't support 4K, resulting in constant buffering.
Do you need an HDMI cable if you have Wi-Fi?
HDMI isn't necessary for basic movie viewing. However, if you want to transmit uncompressed high-resolution audio (such as Dolby TrueHD) to an expensive receiver connected to your TV, a cable can provide a more stable data transfer than wireless protocols.
How to improve picture quality during broadcasting?
Close background downloads on other devices, connect to a 5 GHz network, and make sure your computer isn't in power-saving mode, which can reduce Wi-Fi performance.
Does this work on Mac?
Yes, Apple computers can stream content to a Samsung TV via AirPlay 2 (if your TV model supports it) or using third-party server apps that emulate DLNA.
