Modern technologies make it possible to transform a living room into a fully-fledged multimedia center, and the key element here is the connection between a personal computer and a large screen. Wireless connection eliminates the need to run long HDMI cables across the room, preserving the aesthetics of the interior. If you own the equipment LG, you are lucky, because the system WebOS has excellent compatibility with Windows and third-party protocols.
There are several ways to establish interaction between devices, and the method you choose depends on your goals. You can simply stream photos from your hard drive or duplicate your desktop for games and presentations. In this article, we'll take a detailed look at How to set up a stable connection without lag, using the built-in functions of the router and TV.
Before proceeding with settings, make sure both devices are on the same local network. This is a fundamental requirement for most data transfer technologies to work. Below, we'll cover technical details that will help you avoid common synchronization errors.
Technical requirements and equipment preparation
Successful synchronization directly depends on the quality of your network equipment. Streaming heavy 4K video or gaming requires high bandwidth. If your router only supports the standard 802.11n (2.4 GHz), you may experience some lag when streaming in high quality.
The optimal solution is to use a range 5 GHzIt provides higher data transfer speeds and is less susceptible to interference from neighboring networks and household appliances. Make sure both your computer and TV LG connected to a 5 GHz network, if your router has this capability.
⚠️ Note: Some older router models may not correctly handle multicast traffic required for DLNA. If devices cannot see each other, try temporarily disabling the "AP Isolation" feature in your router settings.
It's also worth checking that your TV software is up to date. LG Go to the settings menu and find the system updates section. Make sure the latest drivers are installed on your computer. Wi-Fi adapter and network card.
Setting up a DLNA server in a Windows environment
Technology DLNA (Digital Living Network Alliance) is the de facto standard for streaming media content. In the Windows operating system, this feature is implemented through the "Streaming Media" component. It's the ideal way to watch movies stored on your PC on a big screen without using flash drives.
To enable this feature, open the Control Panel and go to "Network and Internet." Here you'll need to find "Streaming Media Settings." The system may ask you to confirm enabling this service.
Once activated, you'll see a list of available devices on your network. Find your TV in the list. LG Smart TV and make sure the "Allowed" box is checked. You can also adjust the access level by restricting viewing of specific folders.
- 📁 Open File Explorer and select the folder with the video or photo.
- 🖱️ Right-click and select "Enable media streaming".
- 📺 On the TV remote, press the "Input" button and select the "Device Connector" or "Smart Share" source.
- 💾 Find your computer's name in the list and enjoy the content.
☑️ DLNA Check
It's important to understand that DLNA doesn't mirror your screen; it only streams files. This method isn't suitable for working with documents or browsing. However, for viewing family archives or downloaded movies, it's the most stable option.
Screen casting via Miracast and WiDi
If your goal is to completely duplicate the image from your computer monitor to your TV LG, you will need technology MiracastIn the Windows ecosystem, this is often called "Connect" or "Wireless Display." This allows you to display a live image on your TV, which is useful for presentations or gaming.
On TVs LG This function may be called differently depending on the version. WebOSOn newer models, simply press the signal source selection button and select "Screen Share" or "Mobile Connection." On older models, you may need to launch a separate app.
On a Windows 10 or 11 computer, press the key combination Win + KThe "Connection" panel will appear on the right. The system will begin searching for available wireless displays. When your TV's name appears, click it to begin pairing.
⚠️ Note: Using Miracast significantly increases the load on your Wi-Fi network. If you notice audio and video out of sync, try lowering the display resolution in Windows display settings.
Input lag is important for gamers. Wireless streaming always introduces a small amount of delay, so it may not be ideal for fast-paced shooters or competitive games. However, for strategy games or video viewing, the delay is unnoticeable.
Why does the connection keep dropping?
Frequent connection drops when using Miracast are often caused by power-saving settings on your Wi-Fi adapter. Go to Device Manager -> Network Adapters -> Your adapter's properties -> Power Management and uncheck "Allow the computer to turn off this device to save power."
Using the LG TV Plus app and Smart Share
Company LG developed its own software to simplify interaction with technology. Application LG TV Plus (formerly known as LG Smart View) is available for download in the Microsoft Store. It provides a user-friendly interface for managing content.
After installing the app on your computer, launch it. The program will automatically scan the network and find compatible TVs. Select your device from the list. You may see a connection confirmation prompt on the TV screen—accept it using your remote.
The app interface is divided into several tabs: "Photos," "Videos," "Music," and "Screen." You can drag and drop files directly into the app window for instant playback. A "Screen Split" feature is also available, allowing you to split your TV screen into multiple windows.
| Function | DLNA (Standard) | LG TV Plus | Miracast |
|---|---|---|---|
| Transmission type | Files | Files + Management | Screen mirroring |
| Delay | Absent | Minimum | Depends on the network |
| PC control | Limited | Complete | Complete |
| Format support | Depends on TV | Depends on TV | Any (like on PC) |
Using proprietary software is especially convenient if you want to control playback without leaving the couch. The app turns your computer keyboard and mouse into a TV remote control.
Third-party solutions and browser streaming
Sometimes built-in tools are unstable or don't support the required file format. In such cases, third-party programs come to the rescue. One of the most popular solutions is Plex or KodiThese programs create a powerful media server with automatic downloading of covers and descriptions.
To install the server on a PC, download the distribution from the developer's official website. After installation, add folders with media files to the library. On a TV LG Find and install the Plex client app in the app store.
Another easy way is to use a browser Google ChromeIf you want to show a web page or video from a website, open the browser menu and select "Cast." Select your TV from the list of devices. This method uses the protocol Chromecast, which is supported by many modern LG models.
- 🌐 Open the Chrome browser on your computer.
- ⋮ Click on the three dots in the upper right corner and select "Broadcast".
- 📺 Select source: tab, desktop, or file.
- ▶️ Click on your TV's name to start broadcasting.
It's worth noting that browser streaming can consume more computer resources, as video decoding often relies on the CPU. If your computer is older, native DLNA methods are preferable.
Diagnosing problems and troubleshooting
Even with proper setup, issues may still occur. The most common issue is that the computer doesn't detect the TV, or vice versa. First, check the network type in Windows. If the network is marked as "Public," the system is blocking device discovery. Switch the network profile to "Private" in the Wi-Fi settings.
The second important aspect is firewall settings. Antivirus software or the built-in Windows Defender may block incoming connections. Make sure the firewall exceptions allow the "Media Sharing Services" and "System" applications.
If the image is transmitted but has artifacts or tearing, try rebooting your router. Running the router for a long time can cause the buffer memory to overflow and reduce speed. Also, check to see if your Wi-Fi channel is being overloaded by neighbors using specialized utilities for analyzing the airspace.
⚠️ Please note: TV interfaces and operating systems are updated regularly. The location of menu items or function names may differ from those described in the instructions. Always check the manufacturer's official website for the latest documentation.
If persistent errors occur and nothing else helps, reset your network settings. On a PC, this can be done via the command line with the command netsh winsock reset, and on the TV through the menu "General" -> "Reset to factory settings" (be careful, this will delete your settings).
