Modern televisions Samsung Smart TV Video players have become powerful multimedia centers capable of playing content from a wide variety of sources. However, built-in applications can't always open all file formats or provide access to the media library stored on your desktop or laptop's hard drive. This is where wireless video streaming over a local network becomes necessary.
There are several proven ways to watch movies from your computer on a Samsung TV via Wi-Fi, and the method you choose depends on your goals. You can mirror the entire screen or send a specific media file to the big screen while continuing to work in other operating system windows. Understanding the differences between these technologies will help you avoid lag and audio desync.
In this article, we'll take a detailed look at the technical nuances of setting up a DLNA server, using the Miracast protocol, and working with Samsung's proprietary utilities. We'll cover both standard operating system tools Windows 10/11, as well as third-party solutions that allow you to bypass the limitations of built-in functionality. Proper network configuration is the key to stable, buffer-free high-definition video playback.
Technical requirements and equipment preparation
Before starting setup, make sure your equipment meets the minimum requirements for wireless data transmission. It's crucial that all devices are on the same local network. This means both the computer and TV must be connected to the same router, regardless of whether you're using an Ethernet cable or a wireless connection.
⚠️ Note: If your router broadcasts two networks (2.4 GHz and 5 GHz) with different names, make sure both devices are connected to the network with the higher bandwidth (usually 5 GHz) to avoid stuttering when playing 4K content.
For broadcasting high-definition video, especially when it comes to formats 4K HDR or heavy files HEVCWi-Fi connection speed plays a crucial role. Older wireless standards may not be able to handle the data flow, resulting in constant buffering pauses. It is recommended to use a router that supports the standard. Wi-Fi 5 (ac) or newer.
It's also worth checking the operating system version on your PC. Modern streaming methods, such as Miracast, are deeply integrated into the Windows 10 and 11 kernel, while older versions may require additional drivers for the wireless adapter. Make sure your Samsung TV is running the latest Tizen OS firmware, available through the support menu.
Setting up a DLNA server in Windows
Technology DLNA (Digital Living Network Alliance) is one of the oldest and most reliable methods of transferring media files. It allows the computer to act as a server, simply "distributing" files, while the Samsung TV, with its built-in client, reads and plays them. This method is ideal if you simply want to play a movie and don't need to control playback in real time from the PC keyboard.
To activate this feature in Windows, you need to open the media streaming settings. In operating systems Windows 10 And Windows 11 This can be done through the control panel or by searching for "Media streaming settings." Once enabled, the system will prompt you to select devices that are allowed access to your media library.
Control Panel → Network and Internet → Network and Sharing Center → Media Streaming SettingsIn the window that opens, you'll see a list of available devices on the network. Find your TV in the list. Samsung and set its status to "Allowed." After this, the system will automatically index the standard folders (Videos, Images, Music) and make them visible to TV. You can expand the list of folders by adding directories containing your movies.
☑️ Check DLNA settings
It's worth noting that DLNA doesn't stream your desktop, only files. If you want to watch a video that isn't in the default folders, you'll have to either move the file or add a new folder in the server settings. This method is the least processor-intensive, as the decoding is handled by the TV.
Using the Connect to Wireless Display feature
If your goal is not just to play a file, but to show the contents of the screen, for example, to watch a video from a site that does not support DLNA, or to show presentations, you will need technology MiracastIn the Samsung and Windows ecosystem, this is implemented through the "Projection" or "Connect to a wireless display" function.
On a Samsung TV, the process begins with searching for a signal source. Press the button on the remote control. Source (or Input) and select "Screen Mirroring," "Smart View," or "Connect to Phone" from the list. The interface may have different names depending on the model year. Samsung, but the essence remains the same - the TV goes into connection standby mode.
On a Windows 10/11 computer, use hotkeys Win + KThe "Connection" panel will slide out on the right, and your TV should appear there within a few seconds. After selecting the device, your computer screen will be mirrored entirely on the TV. This creates the effect of a second monitor operating over the air.
⚠️ Please note: When using Miracast, the Wi-Fi adapter and your computer's processor are heavily loaded, as the video stream is encoded in real time. A slight input lag may be observed for games or fast-paced video.
It's important to understand that with this connection, the TV becomes a second monitor. You can choose "Duplicate" or "Extend" mode. In "Extend" mode, the TV desktop will be blank until you drag a browser or media player window there. This gives you flexibility: you can watch a movie on the TV while chatting on your PC monitor.
Why can't I find my device?
If your computer can't see your TV in Miracast mode, check your firewall settings. Sometimes antivirus software blocks incoming connections for the projection function. Also, make sure your Wi-Fi adapter drivers are up to date and support Wi-Fi Direct.
Samsung branded applications and Smart View
Samsung has developed its own software to improve interaction between devices. Although the mobile app Smart View More focused on smartphones, there is a program for PCs Samsung Flow or the ability to use the built-in browser Samsung Internet in conjunction with a PC. However, the most universal solution for PC owners remains using the Cast protocol within the Google Chrome browser.
Browser Google Chrome has a built-in casting function that works with almost all Samsung TVs that support Chromecast built-in Or simply accepting cast requests. After opening a movie in the online cinema directly in your browser, click the three dots in the upper right corner and select "Cast."
The system will prompt you to select a source: you can broadcast just a tab, the entire screen, or a specific file. The advantage of this method is its high compatibility and ease of control. You can use your computer as a remote control, pausing a video or adjusting the volume without leaving the couch.
For users looking for more advanced control, there are dedicated media centers such as Kodi or PlexBy installing the Plex server on your computer and the client app on your Samsung TV (available in the App Store), you get a beautiful interface with posters, movie descriptions, and automatic media library sorting.
Comparison of video signal transmission methods
To help you choose the right connection method, we've prepared a comparison chart. It will help you weigh the pros and cons of each method based on your needs and technical capabilities.
| Method | Image quality | Latency | Ease of control |
|---|---|---|---|
| DLNA | Maximum (original) | Absent | Basic (TV remote control only) |
| Miracast | High (depending on signal) | High (0.5-2 sec) | Full control from your PC |
| Chrome Cast | High (adaptive) | Average | Control from PC/Phone |
| HDMI cable | Ideal | Absent | Full control |
As can be seen from the table, if the priority is image quality and the absence of compression artifacts, then DLNA remains the undisputed leader for local filesHowever, if you need to show something that isn't in the file system or demonstrate how a program works, then Miracast or an HDMI cable are the only options.
It's also worth mentioning that a wired HDMI connection, while not wireless, is often a lifesaver when the Wi-Fi network is overloaded. In today's environment, where numerous neighbors' devices create interference, the stability of a wired connection may be preferable to the freedom of a wireless connection.
Network troubleshooting and optimization
Even with proper setup, users may encounter issues: the TV doesn't detect the computer, the video slows down, or the sound disappears. Most often, the cause lies in the network security settings. In Windows, the network profile must be set to "Private" and not "Public," otherwise the system will block detection of other devices.
To edit your profile, go to Settings → Network & Internet → StatusIn the "Properties" section of your Wi-Fi network, change the profile type to "Private." This will allow your computer to be visible to your Samsung TV. Also, check if your antivirus software is blocking local connections.
⚠️ Please note: Operating system and TV interfaces are updated regularly. The layout of menu items may differ slightly from that described in the instructions. Always consult the latest manuals on the manufacturer's official website if you cannot find the item you need.
If video playback is choppy, try lowering the bitrate or resolution. Your Wi-Fi signal may not be strong enough to handle the heavy data load. In this case, installing an additional router in repeater mode or switching to the 5 GHz band if your router supports dual-band operation may help.
Frequently Asked Questions (FAQ)
Why doesn't my Samsung TV see my computer in the list of devices?
Make sure both devices are connected to the same network (same SSID). Check that network discoverability is enabled in Windows and that the network profile is set to "Private." Also, try temporarily disabling Windows Firewall to test.
Is it possible to broadcast audio separately, without video?
Yes, in Miracast mode, audio is transmitted along with the video. If you use DLNA, the audio is part of the video file. Streaming audio separately (like with Bluetooth speakers) to Samsung TVs using standard Windows tools is difficult; third-party software like AudioRelay is usually required.
Does watching movies on a PC affect internet speed?
When using DLNA or Miracast for local files, the internet is not used; traffic is kept within your home network. However, if you stream online video (via a browser), the internet speed is used just as if you were watching it on a PC monitor.
What video format is best supported by DLNA?
Samsung TVs work great with containers MP4, MKV and codecs H.264, H.265 (HEVC)Formats like AVI with outdated codecs may not play or require conversion on the computer side.
