How to watch movies on a Samsung TV from a computer via WiFi

A modern home theater no longer requires bulky systems and tangled wires that entangle the entire room. All you need is Smart TV from Samsung and a regular laptop or desktop computer connected to the same wireless network. This opens up access to a vast library of content stored on the hard drive, allowing you to view it on a large screen in high definition.

Wireless data transfer technologies such as DLNA and Miracast are built into most models. Samsung Series 6, Samsung Series 7 and newer, making the syncing process incredibly simple. You don't need to be an IT specialist to establish a stable connection and enjoy your favorite movies. Just follow a few simple steps in the device menu.

In this article, we'll take a detailed look at all available methods for streaming images and video files. We'll cover both the built-in capabilities of the Windows operating system and third-party solutions that can be useful in complex situations. Proper setup will eliminate lag and format compatibility issues.

Preparatory stage and network requirements

Before starting the setup, you need to make sure that both devices have equal access to the network. Local area network The network must be set up so that the computer and TV can "see" each other. Most often, problems arise because one of the devices is connected to guest Wi-Fi or using a mobile 4G modem.

Make sure your router supports the standards 802.11n or 802.11ac, as older protocols may not be able to handle 4K video streaming. Connection speed directly impacts the absence of buffering and stuttering when playing heavy content.

  • 📶 Both devices must be connected to the same router (same subnet).
  • 💻 Network discovery must be enabled on your computer.
  • 📺 The TV model must support Smart Hub technology.
  • 🔋 It's best to connect your laptop to a charger to avoid draining the battery while watching videos.

⚠️ Important: If your router has AP Isolation, enable it in the security settings. Otherwise, devices on the same network will not be able to communicate with each other, even if they are in the same house.

Checking the signal stability is an important step. If the router is located in another room behind several walls, the signal may not be strong enough to transmit a high-bitrate video stream. In such cases, it is recommended to use a wired connection for the PC or move the router closer to the viewing area.

Using the built-in DLNA feature in Windows

The easiest and most native way to deliver a movie is to use technology Digital Living Network AllianceThe Windows operating system has a built-in media server that automatically makes content folders available to other devices on the network, including Samsung TVs.

To activate this feature, go to the Control Panel and find the section responsible for media streaming. In Windows 10 and 11, this process is significantly simplified and often works by default if you selected the "Private" network type when you first connected.

Control Panel → Network and Internet → Network and Sharing Center → Media Streaming Settings

Once the feature is enabled, the system will prompt you to select devices that are allowed access. Find your device in the list. Samsung TV and allow access. Now the contents of the default "Videos," "Music," and "Pictures" folders will be available for viewing.

☑️ DLNA Check

Completed: 0 / 1

It's worth noting that DLNA doesn't stream desktop images, only files. This means you won't be able to launch a browser on your TV using this method, but it's ideal for watching saved movies without the need for additional software.

Miracast technology and screen projection

If your goal is to broadcast not a specific file, but the entire computer screen or browser, you will need technology Miracast (In the Microsoft ecosystem, it's called "Connectivity"). This method creates a direct wireless connection between the PC's graphics card and the TV display, broadcasting the video signal in real time.

To start projection in Windows 10/11, use a hotkey Win + KThe system will begin searching for available wireless displays. Make sure the "Screen Casting" app or a similar app is running on your Samsung TV, which puts the TV into connection standby mode.

Picture quality when using Miracast depends heavily on the WiFi channel load. If the network is actively downloading files or playing online games, you may notice compression artifacts or audio desync. For high-bitrate movies, this method may be less stable than DLNA.

  • 🖥️ Suitable for demonstrating presentations or web pages.
  • 🎮 Allows you to run PC games on a big screen.
  • 🔊 Automatically transmits sound through the TV speakers.
  • 📉 May reduce resolution when WiFi signal is weak.
Why does the sound disappear when connected?

Often, after connecting via Miracast, sound continues to come through the laptop speakers. To fix this, click the speaker icon in the Windows tray and manually select the "Samsung TV" or "Intel/AMD/NVIDIA Audio" output device.

Third-party media servers: Plex and Kodi

For users with extensive movie collections with heavy subtitles and complex file structures, built-in Windows tools may not be sufficient. This is where specialized server solutions, such as Plex or KodiThese programs don't just open files, but also create a beautiful shell with posters, descriptions, and trailers.

Installing the server component (for example, Plex Media Server) on your computer takes a few minutes. After scanning your libraries, the program will automatically download movie metadata. On a Samsung TV, simply install the app from the store. Smart Hub and log in to your account.

The main advantage of such systems is the ability to transcode video on the fly (transcoding). If the TV doesn't support the audio format or video codec of the file, a server on the computer converts the stream to a compatible format in real time. This requires a sufficiently powerful processor in the PC.

Parameter Plex Kodi (with plugin) Built-in DLNA
Interface Modern, with posters Customizable with skins Simple file list
Transcoding Auto Requires configuration Absent
Complexity Low High Minimum
Access from outside Yes (via cloud) Configuration required Locally only

⚠️ Warning: When transcoding, the load on your computer's processor may reach 100%. Make sure your PC's cooling system is working properly, otherwise, you may experience dropped frames in the video.

Using media servers is especially useful if you want to access your collection not only in your living room but also on other devices. However, for a simple one-time viewing of a downloaded movie, this may seem like an overkill.

Broadcasting via Google Chrome browser

If you watch movies online through a browser, Google Chrome's built-in feature can be a great way to display images on a larger screen. This method uses technology Chromecast built-in, which is supported by many modern Samsung models.

To start casting, open the Chrome browser on your computer, click the three dots in the upper right corner, and select "Cast." The system will search for available devices. You can cast a specific tab or your entire desktop.

This method is convenient because it doesn't require setting up shared folders or installing servers. However, it is entirely dependent on browser performance and a stable internet connection. If a movie is large and buffering is slow, the TV will be the first to notice.

It's important to note that when casting a tab, audio may not be transmitted by default. You'll need to manually enable the "Broadcast Audio" option in the source selection menu to ensure audio is transmitted through your home theater system or TV speakers.

Troubleshooting connection and buffering issues

Even with proper setup, technical issues can still occur. The most common problem is that the TV doesn't detect the computer on the network. In 90% of cases, this can be resolved by checking the network profile. If Windows considers your network to be "Public," it blocks device discovery for security reasons.

To edit your profile, go to Settings → Network & Internet → StatusClick on the connection properties (WiFi or Ethernet) and switch the network type from "Public" to "Private." This will open ports for local data exchange.

If the video playback is lagging or constantly buffering, try lowering the stream quality or file bitrate. It's also worth checking whether someone else on your network is using your bandwidth to download large amounts of data.

Some antivirus programs (e.g., Kaspersky, ESET, Avast) may block the media server with their built-in firewall. If other methods don't work, try temporarily disabling network protection or adding the media server application to the firewall's exceptions.

Comparison of methods and final recommendations

The best method depends on your specific needs. For casual photo viewing or a single movie, Windows' built-in tools are sufficient. For a full-fledged media library, it's better to invest time in setting up Plex.

Miracast technology is indispensable when you need to share screen content, such as a presentation or a website, but for long movie viewing sessions it may be less comfortable due to possible audio desynchronization.

Please remember that TV software and operating systems are constantly being updated. Menu interfaces and item names may change. If you don't find the function you're looking for, check the "Support" section on your TV manufacturer's official website for the latest manuals.

Why can't my Samsung TV see files from my computer?

The problem is most likely with your Windows network profile (it should be "Private") or with your firewall/antivirus settings blocking access to shared folders. Also, check if media streaming is enabled in Control Panel.

Is it possible to stream 4K video over WiFi?

Yes, but stable 4K content streaming (especially with high bitrates) requires an AC (WiFi 5) or AX (WiFi 6) router and a 5 GHz connection. The 2.4 GHz band can cause constant lag.

Is there a delay in sound when connecting via Miracast?

Audio lag is common when streaming video wirelessly. Try updating your PC's WiFi adapter drivers. If the issue persists, use a wired connection or the DLNA method, which is less sensitive to latency because it buffers the file in advance.

How to improve file transfer speed?

Place the router closer to the TV and computer, removing any physical obstructions. If possible, connect your desktop computer to the router via cable, leaving the WiFi connection for the TV only. This will reduce airtime congestion and improve channel stability.
