Modern technology allows you to transform your living room into a full-fledged multimedia center without the need for unnecessary wires. Connecting a computer to a TV LG Wirelessly access a huge collection of movies, photos, and games on a large screen. This solution is ideal for those who value aesthetics and don't want to clutter their space with cables. HDMI.
The process of synchronizing devices is based on standards Miracast And DLNA, which are built into most modern operating systems and smart TVs. However, despite their apparent simplicity, users often encounter complexities when configuring routers or graphics card drivers. In this article, we'll examine all available methods in detail so you can choose the best option for your situation.
It is worth noting right away that the stability of the connection directly depends on the quality of your Wi-Fi Network. If the router is in the next room or behind thick walls, image lag may occur. For the best experience, ensure both devices are within range of a strong signal.
Preparatory stage and network requirements
Before you begin setup, you need to make sure your equipment meets the basic requirements. Your computer and TV must be on the same local network. This means they are connected to the same router, either via cable or wirelessly.
For TVs LG with the operating system webOS The procedure is extremely simplified. You won't need to install third-party apps on your TV, as the functionality is already built into the firmware. However, on your computer, some steps may be required, especially if you're using an older version. Windows.
Pay attention to the Wi-Fi network frequency. For high-definition video streaming (Full HD and 4K), it is highly recommended to use the frequency range 5 GHzIt provides higher throughput, which is critical for minimizing delays in image display.
⚠️ Important: If your router broadcasts two networks with the same name (2.4 GHz and 5 GHz), make sure your PC and TV are connected to the 5 GHz band. Mixed connections (one device on 2.4 GHz, the other on 5 GHz) can prevent the devices from discovering each other on some router models.
Also, check that your software is up-to-date. Outdated wireless adapter drivers on your laptop may not work correctly with mirroring protocols. Update them through Device Manager or the manufacturer's website.
Miracast Method: Built-in Windows and LG Function
The fastest way to display a screen is to use technology MiracastIn the operating system Windows 10 And Windows 11 This function is called "Connection" and does not require the installation of additional software. TVs LG support this protocol out of the box, called Screen Share.
To start working, press the button on the remote control. Input or select from the application launcher menu Screen ShareOn some models webOS This app may be called "Connection Manager." After launching, the TV will enter connection standby mode.
On your computer, press the key combination Win + KThe "Connection" panel will open on the right, where the system will begin searching for available displays. Your TV should appear in the list. LGClick on it, and after a few seconds the image from the monitor will be duplicated on the big screen.
- 📺 Duplicate mode: The image on the TV completely replicates the contents of the PC screen, which is convenient for presentations.
- 💻 Extension mode: The TV becomes a second monitor onto which you can drag program windows.
- 🎮 Game mode: Some models LG Automatically switch to low latency mode when game content is detected.
If the connection is successful, you can control the projection modes through the menu. ProjectA desktop extension is available here, allowing you to watch a movie on your TV while working on documents on your laptop.
DLNA Setup: Media Streaming
If your goal is not screen mirroring, but playing video files, photos or music stored on your hard drive, it is better to use the protocol DLNAThis method is less demanding on Wi-Fi signal strength, as it does not require real-time video streaming at a high frame rate.
IN Windows The feature is called "Media Streaming." To enable it, open the Control Panel, go to "Network and Internet," then "Network and Sharing Center." In the left menu, select "Media Streaming Settings" and enable this option.
After activation, find your TV in the list of devices LG and make sure it has access rights. Now, open any video file using the default player. Windows Media Player or "Movies & TV," you'll see the "Cast to Device" button. Select your TV, and playback will begin on the big screen.
For more advanced content management, you can use third-party media servers such as Plex or Universal Media ServerThey automatically collect metadata (posters, descriptions) and create a beautiful library accessible through the app. LG Content Store.
⚠️ Note: The DLNA protocol does not support real-time transmission of system notification sounds or audio from browser tabs. It is intended solely for file playback.
Using the LG TV Plus app
Owners of smartphones and tablets often use a proprietary application LG TV Plus, but few people know that its PC counterpart also exists and can be useful. The official Windows app allows you to control your TV and stream content, although its functionality may be limited compared to the mobile version.
You can download the application from the store. Microsoft StoreAfter installation, launch the app and follow the pairing instructions. You may be asked to enter the code displayed on the TV screen to confirm the connection security.
The main advantage of this method is the ability to control the TV with a keyboard and mouse. You can type text into the YouTube search bar on the TV using your computer's full keyboard, which is much more convenient than typing with the remote.
What should I do if the app doesn't detect the TV?
Make sure Windows Firewall isn't blocking the LG TV Plus app. Add it to the exceptions list in your network security settings (Private networks).
Connection Method Comparison Table
To help you choose the right method, we've prepared a comparison table of the key characteristics of each method. It will help you understand which option is best suited to your needs.
| Method | Latency | Image quality | Best use |
|---|---|---|---|
| Miracast | Low / Medium | High (up to 4K) | Presentations, browser, photos |
| DLNA | Absent | Original file | Watching movies and TV series |
| LG TV Plus | Low | Depends on the content | Management, YouTube, photos |
| HDMI (cable) | Minimum | No losses | Games, working with graphics |
As the table shows, for high-motion gaming, wireless methods may be inferior to cable connections due to the inevitable video stream compression. However, for watching movies, the difference is practically negligible.
Troubleshooting and error correction
Despite the standardization of technologies, users often encounter situations where the computer cannot see the TV or the connection constantly drops. One common cause is network configuration. Windows.
Check your network type. If your network is marked as "Public," Windows is blocking device discovery. Switch your network profile to "Private." You can do this through the network settings in the system tray or through the command line.
Another problem is the outdated standard Wi-Fi DirectIf your router is very old, it may not support the necessary data transfer protocols between devices within the local network. In this case, updating the router's firmware or replacing it will help.
- 🔄 Reboot: Simply turning your router, TV, and PC off and on solves 80% of connection problems.
- 🔒 Antivirus: Third-party firewalls may block ports required for Miracast. Try temporarily disabling them.
- 📶 Wi-Fi channel: Airwave congestion from neighboring routers can cause interference. Change the channel in your router settings to a less congested one.
⚠️ Note: Menu interfaces and item names may vary depending on the webOS version and your LG TV model. If you don't find the option described, check the "General" or "Connections" section in your TV settings.
☑️ Connection diagnostics
Optimizing your wireless connection
To ensure a stable picture without stuttering or choppy video, it's important to minimize the number of devices actively using the internet while streaming. If someone in the next room starts downloading torrents, the quality of the stream on the TV may degrade.
Use the standard Wi-Fi 6 (802.11ax), if your equipment supports it. This standard manages multiple connections much more efficiently and reduces latency. It's also worth considering installing a repeater or mesh system if the TV is located far from the router.
Keep in mind that metal objects, mirrors, and aquariums between the router and TV can significantly weaken the signal. Try to ensure a clear line of sight or minimize obstructions.
