Modern technologies make it possible to transform your living room into a fully-fledged multimedia center, eliminating the hassle of unnecessary wires and complex HDMI cable management. If you're wondering how to connect your computer to your LG TV via Wi-Fi, you're in luck: the webOS ecosystem and built-in protocols in Windows 10 and 11 make this process as simple and accessible as possible, even for beginners. A wireless connection allows you to watch movies, present presentations, and play games on the big screen without losing image quality.
The process is based on the use of a local Wi-Fi network, through which video streams and control commands are transmitted. Smart TV LG's TVs support several media streaming standards, including Miracast for screen mirroring and DLNA for file playback. It's important to understand that for stable operation, both devices—your laptop and TV—must be on the same subnet, meaning they must be connected to the same router.
Before you begin setting up, make sure your router supports the standards. 802.11n or 802.11ac, as older models may not handle Full HD or 4K video streams. It's also worth checking that your TV has the latest firmware version, as manufacturers frequently release patches to improve compatibility with new PC operating systems. Below, we'll cover all available connection methods and potential issues in detail.
Preparing equipment and network
The first step to wireless synchronization is to properly configure your network environment. Your computer and LG TV must be connected to the same wireless network. If you have a dual-band router broadcasting 2.4 GHz and 5 GHz networks, it's recommended to connect both devices to the same band. 5 GHzThis will provide higher bandwidth, which is critical for transmitting high-resolution video signals without delays and compression artifacts.
In Windows, you need to check your network connection status. The system should recognize your network as "Private" and not "Public," as many device discovery features are disabled by default for security reasons in the Public profile. To do this, go to Network settings and ensure that network discovery and file sharing are enabled.
- 📶 Make sure your router is working properly and is distributing IP addresses to both devices.
- 🔒 Check if the Wi-Fi password is the same on both devices if the network is hidden.
- 🔄 Restart your router if your network is slow or you experience connection drops.
Pay special attention to the wireless adapter drivers on your computer. Outdated software may not correctly support wireless display protocols. Open Device Manager, find your network adapter, and check for updates through the laptop or motherboard manufacturer's website.
⚠️ Note: If your router has the "AP Isolation" feature, wireless mirroring will not work because the devices will not be able to see each other. Disable this feature in your router settings.
After completing the basic checks, you can proceed to setting up the TV. In the LG menu, this is done by launching the "Screen Share" app, which activates connection standby mode. The app name may vary depending on the model year and webOS version.
Using the Cast Screen feature in Windows
The fastest way to connect your computer to an LG TV via Wi-Fi doesn't require installing any third-party software if you're using Windows 10 or 11. These operating systems have a built-in Miracast protocol, which is fully compatible with LG TVs. To get started, simply press a key combination. Win + K on the keyboard.
The "Connection" panel will appear on the right, where the system will begin searching for available displays. If the TV is turned on and in connection standby mode (or simply turned on and connected to the same network), it will appear in the list. Click on the name of your LG TV, and after a few seconds, the desktop image will appear on the big screen.
⚠️ Note: When connecting for the first time, a confirmation message may appear on the TV screen. Use your remote control to press "Accept" or "Confirm," otherwise the connection will not be established.
After successful pairing, you can control the display mode via the "Project" menu, which is called up by the same combination Win + K or Win + PThe available modes are duplicate (screen copy), extend (second desktop), and use only the second screen (the PC screen goes dark).
It's important to note that Miracast technology creates a direct Wi-Fi Direct connection or uses a local network to transmit the video stream with minimal latency. However, image quality may vary depending on the network congestion. If you notice cursor jitter or audio desync, try lowering the screen resolution in Windows settings or moving your laptop closer to the router.
☑️ Check before connection
Setting up DLNA and playing media content
If your goal is not to duplicate your desktop, but to view movies, photos or listen to music stored on your computer's hard drive, then it is better to use the technology DLNAThis method is less resource-intensive and allows the LG TV to act as a renderer, playing files directly from the PC.
To implement this scenario, you need to enable media streaming in Windows. Go to "Media Streaming Settings" in Control Panel or Search and click "Turn on media streaming." In the list that opens, find your LG TV and check "Allowed."
Next, launch the "Photos & Videos," "Music," or webOS's built-in universal media player app on your TV. Select your computer from the list of sources. The folder structure will be displayed as a tree, making it easy to find the files you need.
| Parameter | Miracast (Broadcast) | DLNA (Media) |
|---|---|---|
| Purpose | Screen mirroring, presentations | View videos, photos, music |
| Delay | Minimal, but possible | None (buffering) |
| Control | From a computer | From the TV remote control |
| Formats | Any (like on PC) | Supported TV codecs |
It's worth remembering that DLNA doesn't transmit the Windows interface. You won't be able to launch a game or browser on your TV using this method. It's a purely file-based protocol. If your TV isn't detecting your computer, check your antivirus and firewall software—they often block incoming connections from media servers.
Why can't my TV see files in Certain formats?
Some video formats (such as MKV with certain codecs or AV1) may not be supported by the built-in LG player. In this case, install the VLC app on your TV or use transcoding.
Official LG control apps
LG has developed its own software that greatly simplifies interaction between devices. The application LG TV Plus (available in the Microsoft Store) allows you to not only mirror your screen but also use your smartphone or tablet as a remote control and transfer files. However, for connecting a PC, the app on the TV itself is more often used.
On LG webOS TVs, you can find the "Screen Share" or "Smart View" app in the LG Content Store. Launching it puts the TV into active search mode. This is especially useful if the standard Windows tool Win + K does not find the device.
You can also use a browser. Some LG models allow you to open web pages directly on the TV. You can open a video site (such as YouTube or an online movie theater) on your PC and, if the TV browser supports it, simply enter the address. However, a more elegant option is to use the "Smart Share" feature to transfer Chrome browser tabs.
- 📱 Install the LG ThinQ app on your smartphone for advanced control.
- 💻 Use the Google Chrome browser on your PC to cast tabs via the "Cast" menu.
- 📂 For DLNA, make sure your media folders are shared.
Using official tools often provides better stability, as they are optimized specifically for LG protocols. Unlike universal Miracast drivers, proprietary apps may offer additional features, such as mouse control from a laptop touchpad or keyboard.
⚠️ Note: The interface and app names in the LG Content Store may vary depending on your region and webOS version. If you can't find an app by name, try searching for keywords like "Share," "Cast," or "Screen."
Troubleshooting connection issues
Despite technology standardization, users often encounter situations where the computer can't see the TV or the connection constantly drops. One of the most common causes is a different network type. As mentioned earlier, if Windows considers the network public, it hides the PC from other devices. Change the network profile to "Private" in the Wi-Fi settings.
Another common issue is codec or format incompatibility when using DLNA. The TV may see the computer but not play the file. In this case, installing a third-party media server, such as Universal Media Server or PlexThese programs take care of transcoding video on the fly into a format that the TV can understand.
If the image is choppy or has low resolution:
- Move closer to the router.
- Disable downloads on other devices.
- Try changing the screen refresh rate in Windows display settings.
It's also worth checking your Wi-Fi adapter's power-saving settings. In Device Manager, under the wireless adapter's properties, on the "Power Management" tab, uncheck "Allow the computer to turn off this device to save power." This will prevent random connection drops when the device is idle.
Alternative methods and third-party software
When standard methods don't work or advanced features are required, third-party programs come to the rescue. One of the most popular solutions is AirServer or ApowerMirrorThey are installed on a PC and often emulate an AirPlay or Miracast receiver, providing a more stable connection and the ability to record your screen.
NVIDIA and AMD graphics card owners have dedicated utilities. For example, GeForce Experience lets you stream games from your PC to other devices on the network, including Smart TVs, if they have the appropriate client or browser installed. This is a great way to play games from the comfort of your couch using a gamepad connected to your PC.
The Google Chrome browser also has a built-in casting feature. Open the menu (the three dots in the corner) and select "Cast...". The browser will detect Chromecast built-in devices (available in all modern LG TVs) and allow you to cast a tab or the entire desktop. This is convenient for sharing presentations or web content.
In conclusion, the choice of method depends on your needs. Miracast is ideal for office work and interface sharing. For watching downloaded movies, DLNA is a good choice. For internet streaming or gaming, specialized apps or the Chrome Cast feature are better.
Why can't my LG TV find my computer via Wi-Fi?
Most often, the problem lies in the Windows network profile settings (set to "Public") or whether access point isolation is enabled on the router. Also, check if your antivirus software is blocking network connections.
Is it possible to connect a computer to a TV without a router?
Yes, using Wi-Fi Direct technology. This connects your computer directly to the TV's wireless module, creating its own network. However, the speed and stability of this connection may be lower than using a router.
Is there any audio delay when connected via Wi-Fi?
A small amount of latency is inherent in wireless technologies. When watching video, this is compensated for by buffering, but when gaming or working with audio, it can be noticeable. For gaming, we recommend using a wired connection or Game Mode on your TV.
Do all LG TVs support Wi-Fi connectivity?
Almost all modern Smart TV models (webOS 3.0 and above) support Miracast and DLNA. Older models (2012-2014) may require an additional USB Wi-Fi adapter or external set-top boxes.
