Modern technology allows you to completely eliminate unnecessary wires, transforming your living room into a true multimedia center. Connecting your computer to your TV via Wi-Fi in Windows 10 takes just a few minutes, using the operating system's built-in features. This allows you to watch movies, present presentations, and surf the web on a large screen without running HDMI cables across the room.
To successfully sync your devices, make sure both devices are on the same local network. Wireless display This is a standard feature supported by most modern Smart TVs and laptops. If your router is working properly, the setup process will take no longer than launching a regular app.
In this article, we'll cover the main streaming methods, including Miracast and DLNA protocols. You'll learn how to set up screen projection, which network settings are critical, and how to avoid common pairing errors. Windows 10 interface provides flexible tools for media management that are often underestimated by users.
Technical requirements and equipment preparation
Before you begin setup, you need to make sure your equipment meets the minimum requirements for wireless video streaming. The key requirement is a Wi-Fi module on your computer and support for the technology. Smart TV on your TV. Most models released after 2015 already have built-in mirroring receivers.
It's important that both devices are within range of a strong signal. If the router is located far away, image quality may degrade, artifacts may appear, or audio may lag. To test the connection, simply open any website on your PC and ensure it loads quickly and without errors.
β οΈ Note: If your TV does not have a built-in Wi-Fi module, but supports USB ports, you can use special Wi-Fi adapters (dongles), however, their setup requires separate instructions and is not guaranteed by Windows standards.
Make sure your TV has the wireless function enabled. On some models, it may be called Screen Mirroring, Wireless Display or ProjectorWithout enabling this option, the computer simply won't see the target device in the list of available devices.
Setting up the Projection feature in Windows 10
Windows 10 has a built-in tool for connecting to wireless displays. To activate it, you don't need to download any third-party software. Simply use the system quick access menu, which can be accessed with a keyboard shortcut or through the system settings.
Press the keys simultaneously Win + K on the keyboard. The "Connection" panel will open on the right, where the system will begin searching for available devices. If the TV is correctly configured and connected to the network, its name will appear in the list within a few seconds.
βοΈ Checking connection readiness
After selecting your TV, a connection confirmation prompt may appear on the screen. Accept it using the remote control. Miracast protocol, used by default, creates a direct Wi-Fi connection between devices, which ensures minimal delay in image transmission.
If the connection is successful, your computer screen will be fully or partially displayed on the TV. In the "Projection" menu, you can select the display mode: screen mirroring, desktop extension, or using the TV as a separate monitor.
Using DLNA technology for multimedia
If your goal is not to duplicate the desktop, but to play video files or photos, it is more convenient to use the protocol DLNAThis method allows you to stream content from your computer's folders to your TV without overloading the processor with the extra work of encoding the entire screen.
First, you need to open "Media Streaming Settings." Type "Streaming Settings" into Windows Search and navigate to the appropriate section. Here, you need to enable the feature and ensure your TV is listed as an allowed device.
| Parameter | Description | Recommended value |
|---|---|---|
| Net | Connection type | Private network |
| Permission | Device access | Allowed for everyone |
| Quality | Video bitrate | High (1080p/4K) |
| Formats | Supported codecs | MP4, MKV, AVI |
Once set up, find the video file on your computer, right-click it, and select "Cast to device." Select your TV from the list. Playback will begin automatically, and you can control it using the standard Windows media player.
The advantage of DLNA is that the computer can be locked or used for other tasks while the video is playing on the TV. However, this method is not suitable for sharing a browser or games, as only a specific file is streamed.
Connection via manufacturer's proprietary applications
Many TV manufacturers develop their own utilities to simplify interaction with a PC. For example, owners Samsung can use the Smart View app, and users LG β LG TV Plus. These programs often offer a more stable connection and additional control features.
Such applications should be downloaded only from the official websites of the manufacturers or from the store. Microsoft StoreThird-party programs may contain ads or may not work correctly with newer versions of Windows. After installation, the utility will automatically find the TV on the network and prompt you to connect.
β οΈ Please note: App interfaces and names may change after TV firmware updates. If the default app isn't working, check your TV's app storeβthe manufacturer may have released a new software version.
Proprietary software often allows you to use your smartphone or computer as a remote control, which is convenient when watching movies. These programs can also transfer files directly to the TV's memory if the model supports USB recording.
What should I do if the app doesn't detect the TV?
Make sure Windows Firewall isn't blocking the connection. Try temporarily disabling your antivirus or adding the app to the exceptions list. Also, check if UPnP is enabled in your router settings.
Network setup and troubleshooting
A common cause of connection issues is an incorrectly configured network profile. Windows should consider the current network as "Private" rather than "Public." In a public profile, the system blocks detection of other devices for security reasons.
To change your profile, go to Settings β Network and Internet β Wi-FiClick on your network name and select the "Private" profile type. Then try searching for the TV again through the projection menu.
If the image is choppy or the sound is missing, try lowering the resolution or refresh rate in Windows display settings. High bitrates may not be able to penetrate the broadcast, especially if the Wi-Fi channel is busy with neighboring networks.

- π Restart your router, computer, and TV one by one.
- π‘οΈ Update your wireless adapter drivers through Device Manager.

Comparison of connection methods and final recommendations
The choice of connection method depends on your specific needs. For gaming and presentations, Miracast mirroring is indispensable. For watching downloaded movies in high quality, DLNA is better, as it places less load on the system and provides a more stable image.
If you plan to frequently use your TV as a second monitor, it's a good idea to purchase a dedicated Microsoft Wi-Fi adapter or similar product to simplify initial pairing. Built-in TV modules are sometimes slower than dedicated receivers.
Keep in mind that a wireless connection will always have a slower response time than a wired one. For eSports games or working with fast-paced content, latency can be noticeable. In such cases, it's best to use an HDMI cable if possible.
Why doesn't the computer see the TV in the list of devices?
Most often, the problem lies in different subnets (for example, one device on 2.4 GHz and another on 5 GHz, with separate networks) or an antivirus blocking the connection. Also, make sure the signal reception app is open on the TV.
Is it possible to transmit sound separately from the image?
Yes, in Windows sound settings (Control Panel β Sound) you can select the TV as the default output device, leaving the image on the PC monitor, if the TV supports this mode of operation.
Does connecting to a TV affect the internet speed on a computer?
When using DLNA, traffic flows within the local network and doesn't consume internet bandwidth. Mirroring (Miracast) also doesn't consume internet bandwidth because the connection is direct, but overall Wi-Fi bandwidth may decrease.
