Modern Smart TV from the company Samsung Offer users a wide range of multimedia options, allowing them to transform a regular TV into a fully-fledged entertainment center. One of the most popular features is wireless image transmission from a personal computer or laptop to a large screen, eliminating the need for long HDMI cables.
In this article, we will examine in detail all the current methods for synchronizing devices on a single network. Wi-FiYou will learn about the native functions of the operating system. Windows, using the standard Digital Living Network Alliance and specialized applications for content streaming.
There are several basic protocols that ensure stable video signal transmission, and the choice of a specific method depends on your TV model and software version. The most universal solution for users Windows 10 And Windows 11 is a technology Miracast, which allows you to completely duplicate your desktop without installing additional software.
To implement this method, you need to make sure that both the computer and the TV Samsung Connected to the same wireless access point. This is critical, as the router acts as an intermediary, routing the video stream between devices.
On the TV side, often no complex settings are required, however, in some models of the series J, K, M You may need to activate the "Mircaste" or "Screen Cast" function in the signal source menu. Modern models of the series T and newer support automatic device detection.
⚠️ Note: If your router supports frequency splitting, make sure both devices are on the same subnet (e.g. both on 2.4 GHz or both on 5 GHz), as some older routers isolate clients on different bands.
The connection process via built-in Windows tools is extremely simple and takes just seconds. You don't need to search for or download drivers if your operating system is up to date.
To start broadcasting, press the key combination Win + K on your computer keyboard. The "Connection" panel will open on the right, where the system will begin searching for available wireless displays within range.
Once your TV's name appears in the list Samsung, click on it. A connection confirmation prompt may appear on the TV screen, which you'll need to accept using your remote control.
Setting up DLNA to view media files
If your goal is not to duplicate your desktop, but to view photos, videos or listen to music stored on your PC's hard drive, then the technology DLNA will be the optimal solution. This protocol allows the TV to view computer folders as external media storage.
In the operating system Windows You need to open "Streaming Media Settings" through the Control Panel or search. Here, you need to allow access to media files for the device with the same name as your TV. Samsung.
After setting up access, press the button on the TV remote control Home or Smart Hub and go to the "Media" section. You'll see your computer in the list of sources.
- 🖥️ Desktop — full screen duplication for presentations or games.
- 📂 Local files — access to videos and photos without copying them to a flash drive.
- 🌐 Online streaming — broadcasting Chrome or Edge browser tabs.
Using DLNA has its advantages, as the load on the computer's processor during video playback is minimal: the TV decodes the video stream itself. However, playback controls (such as rewinding and pausing) are only available using the TV remote, not the PC keyboard.
Using the Wireless Monitor feature in Windows
Operating systems Windows 10 And Windows 11 have built-in functionality that turns the computer into a signal source for a projector or TV. This function is based on the standard Miracast and provides low-latency image transmission.
Unlike DLNA, this method transmits a video stream from the graphical interface, allowing you to run any applications, browsers, and games on a large screen. Image quality depends on the power Wi-Fi adapter and wireless channel congestion.
To improve connection stability, it is recommended to use a router that supports the standard Wi-Fi 5 (ac) or Wi-Fi 6 (ax)In the router settings, it is advisable to prioritize traffic for multimedia devices (QoS).
☑️ Check before connection
If your TV doesn't appear in the list of available devices, check your firewall settings. Sometimes the system firewall blocks incoming connections for the "Public Network" profile.
Switch the network type to "Private" in the Wi-Fi settings to allow devices to discover it. Also, ensure that the "Projecting to this PC" service doesn't conflict with your attempt to connect to an external network.
Broadcasting via Google Chrome browser
If standard Windows tools don't work correctly or you're using an alternative operating system, a browser is a great solution. Google ChromeIt has a built-in function. Cast, which supports the Chromecast protocol, emulated by modern TVs Samsung.
To get started, open your browser and click the three dots in the upper right corner, then select "Cast." You'll be prompted to select a source: a single tab, your entire desktop, or a specific file.
Selecting the "Cast Desktop" option will stream the image in high resolution. It's important to note that this method may place additional load on the processor, as the browser is encoding the video stream.
Why might the sound lag?
When streaming through a browser, audio lag is often caused by insufficient buffering. Try closing unnecessary tabs or lowering the video quality in the stream settings.
The advantage of this method is that it is cross-platform: you can broadcast content even from Linux or macOS, if the TV supports the Chromecast built-in protocol. Models Samsung 2019 and newer models have this feature out of the box.
Older models may require installation of an app. Smart View to a computer, which also uses similar data transfer principles, but has more limited functionality compared to native Windows tools.
Connecting a Mac and AirPlay 2
Computer owners MacBook or iMac can use technology AirPlay 2, which is integrated into many modern televisions SamsungThis allows you to transmit images and sound without installing additional programs.
Make sure AirPlay support is enabled on your TV in the settings. General → Apple AirPlay SettingsAfter enabling this option, your Mac will see your TV as an available display in the Audio and Video Output menu.
AirPlay 2 streaming quality is generally higher than Miracast due to codec optimization for the ecosystem. AppleInput lag is minimal, making even casual gaming possible.
⚠️ Note: TV menu interfaces may differ depending on the Tizen OS firmware version. If you don't see the AirPlay option, check for system updates in the "Support" section.
Comparison of connection methods
To help you choose the right method, we've prepared a comparison table of the key characteristics of each method. It will help you prioritize image quality, convenience, or versatility.
| Method | Quality | Delay | Complexity |
|---|---|---|---|
| Miracast (Win+K) | High | Low | Minimum |
| DLNA | Maximum | No | Average |
| Chrome Cast | Average | Average | Low |
| AirPlay 2 | High | Low | Minimum |
As the table shows, DLNA is best for watching high-bitrate movies, as the TV handles the file processing itself. For gaming or working with documents, Miracast or AirPlay 2 are ideal.
Using third-party applications is only justified if the standard tools do not work due to software conflicts or outdated hardware.
Solution and optimization
A common problem with wireless transmission is audio and video desynchronization or intermittent image flickering. This is almost always due to an unstable signal. Wi-Fi or channel overload by neighboring routers.
Try switching your router to a less congested channel or using the 5 GHz band, which is less susceptible to interference from household appliances. It's also worth checking if there are any background downloads running on your computer that are consuming your bandwidth.
If the image is black and white or has artifacts, check the screen resolution settings in Settings → System → Display. Make sure it matches the native resolution of the TV matrix, for example 1920×1080 or 3840×2160.
