Modern Smart TV have become powerful multimedia centers that allow you to display content from other devices without the need for extra wires. Connecting a TV LG to the computer via Wi-Fi It gives you access to a huge collection of movies, photos, and even your desktop right on the big screen. This eliminates the need to run long HDMI cables across the room, keeping the interior aesthetically pleasing and clean.
The setup process may vary depending on your PC's operating system and TV software version. There are several basic data transfer methods: using technology Miracast, protocol DLNA or proprietary applications. Each has its own features, advantages, and use cases, which we'll explore in detail in this article.
Before you begin, make sure both devices are connected to the same wireless network. This is critical, as the router acts as an intermediary, transmitting the video stream and control commands between the computer and TV. LGIf the devices are on different subnets, discovery will not be possible.
Technical requirements and equipment preparation
To successfully implement a wireless connection, your equipment must meet certain minimum requirements. This primarily concerns support for wireless communication standards by both devices. Most modern models LG, released after 2014, are equipped with a built-in module Wi-Fi Direct, which significantly simplifies the task.
The computer must also have a working Wi-Fi adapter. If you're using a desktop PC without a built-in module, you'll need an external USB adapter that supports 802.11n or higher. Older protocol versions may not provide sufficient bandwidth for high-definition video.
⚠️ Important: Make sure Client Isolation is not enabled on your router. This feature blocks data exchange between devices within the local network, making connection impossible.
Check that your software is up to date. On TVs LG with the operating system webOS Manufacturers regularly release updates that improve connection stability. For Screen Share to work on some older models, you may need to install the additional "Smart Share" app from the LG Content Store.

- 💻 A PC or laptop with a working wireless adapter.
- 📡 A router operating in the 2.4 GHz or 5 GHz range.
- 🔌 Stable power supply for both devices.
Connect via the built-in Screen Share (Miracast) function
The fastest way to broadcast an image of the entire desktop or a specific window is to use technology MiracastIn the ecosystem LG This function is often called Screen ShareIt enables real-time video transmission with minimal latency, making it ideal for presentations or web browsing.
To start working, press the button on the TV remote control. Input or find the application in the main menu Screen ShareOnce launched, the device name and connection status will appear on the screen. Some models may require confirmation of the connection request using the remote control.
On a computer running Windows 10 or 11, go to the action center and select the option ProjectThe system will begin searching for available displays. If the TV LG If it doesn't show up right away, make sure the detection feature is active in your TV settings.
☑️ Check before connecting Screen Share
After selecting your TV from the list, Windows will establish a connection. You can choose to mirror your screen or extend your desktop. In extend mode, your TV will act as a second monitor onto which you can drag application windows.
What should I do if the connection keeps dropping?
If the connection is unstable, try switching your router to a less congested channel or moving your computer closer to the router. Disabling your antivirus software while checking may also help.
Stream media via DLNA and Smart Share
If your goal is to play movies, music or photos stored on your hard drive, then the technology DLNA This is the best option. It doesn't require screen mirroring, which reduces the load on your computer's processor and allows you to control playback directly from your TV remote.
In Windows, you need to set up folder sharing. Open "Streaming Media Settings" in Control Panel and allow access for the device. LG TVAfter this, the files in the marked folders will become visible to the TV.
Launch the app on your TV. Photos and videos or Smart ShareSelect your computer from the list of sources. The folder structure will be displayed as a tree, making it easier to navigate your PC's file system.
| File format | LG TV support | Recommended codec | Maximum resolution |
|---|---|---|---|
| MP4 | Full | H.264 / H.265 | 4K UHD |
| MKV | Full | HEVC | 4K UHD |
| AVI | Limited | Xvid / DivX | 1080p |
| FLV | No | - | - |
It's important to note that some specific audio or video formats may not be supported by the TV's built-in player. In such cases, the system will prompt you to install a third-party app or convert the file.
Using third-party software
Standard tools don't always provide the desired functionality or stability. In such cases, third-party programs designed specifically for interaction between a PC and Smart TVThey often have more flexible buffering settings and support more formats.
A popular solution is to use media servers such as Plex or KodiInstalling the server part on the computer and the client application on the TV LG Creates a unified media library with a beautiful interface, movie posters, and descriptions.
For those who need to broadcast Chrome browser tabs, there is a built-in function CastBy clicking the browser menu and selecting "Cast," you can display the contents of the tab on your TV. This is convenient for watching online videos from sites that don't have a native TV app.
⚠️ Note: Third-party applications may consume additional system resources. Make sure your computer has sufficient RAM for background server operation.
Some apps allow you to control playback from your smartphone, using it as a remote control. This is especially convenient when you need to quickly find a specific track or movie in a large library without leaving the couch.
Configuring network and router settings
The quality of your wireless connection directly depends on your local network configuration. For high-definition (4K) video transmission, the standard 2.4 GHz band may be insufficient due to low speeds and interference from neighboring networks.
It is recommended to use a range 5 GHz, if your router and TV LG support this standard. It provides higher throughput and is less susceptible to interference. However, its range is shorter, so devices must be relatively close to each other.
Check your router's encryption settings. It's using an outdated security standard. WEP or WPA/TKIP may limit connection speed. The optimal choice is WPA2-AES or WPA3.
If you're using a mesh system, make sure your computer and TV are connected to the same node, or that seamless roaming is configured correctly. Sometimes devices get stuck on different access points, which breaks the logical connection.
Diagnostics and problem solving
Despite the ease of setup, users may encounter various difficulties. Most often, the problem is that the computer simply doesn't see the TV in the list of available devices. This is usually resolved by checking the Windows Firewall.
In your firewall settings, you must allow the Media Player or Projection app to access private and public networks. Without this permission, the operating system blocks incoming requests from the TV for security reasons.
Another common issue is audio and video desynchronization or intermittent image flickering. This indicates insufficient bandwidth or an overloaded processor.
- 🔄 Reboot the router and both devices.
- 🛡️ Check your antivirus and firewall settings.
- 📶 Switch your Wi-Fi channel to a less busy one.
- 📉 Reduce the quality of the streamed video in the app settings.
If nothing helps, try resetting the network settings on your TV. LG through the menu Settings → Network → Advanced Wi-Fi settings → Change password (by entering the wrong password, you can initiate a reset, or look for the "Network reset" item depending on your webOS version).
Why isn't my LG TV showing up in the list of available devices?
The most common cause is that the devices are on different networks (for example, one on the guest network and the other on the main network) or client isolation is enabled on the router. Also, check if your antivirus software is blocking network discovery.
How to reduce latency when gaming over Wi-Fi?
When gaming, a wireless connection via Miracast will always have latency. To minimize this, use the 5 GHz band, disconnect other devices from your Wi-Fi, and, if possible, use "Game" mode in your TV's picture settings.
Is it possible to transmit sound to external speakers via Wi-Fi?
Yes, if your speaker system supports Wi-Fi or Bluetooth technology and is on the same network, or if your TV is Bluetooth Surround Ready for connecting compatible LG soundbars.
