The first and most important step is to check the technical capability of your devices to communicate with each other. Most modern LG TVs released in the last 10 years are equipped with a Wi-Fi module and support the technology. Miracast (often labeled as Screen Share). However, older models may require an external adapter or wired connections.
You need to make sure both your laptop and TV are connected to the same wireless network. This is critical: if your computer is connected via Ethernet and your TV is connected via Wi-Fi, they must be on the same network segment (subnet), otherwise, the devices will not be discoverable. Your router must not have Client Isolation enabled, which prevents devices on the network from seeing each other.
Please note the operating system version on your laptop. Windows 10 and 11 support wireless displays natively, while older versions, such as Windows 7, may require additional drivers or third-party software. Check for updates to your network adapters.
Setting up Screen Share on an LG TV
Before searching for a TV from your computer, you need to activate signal reception mode on the display device itself. This is fairly easy to do in the webOS interface, but the menu layout may vary slightly depending on the firmware version. You'll need a remote control. Magic Remote or a standard LG remote control.
Press the "Home" or "Smart" button on the remote to open the main menu. Find the app called "Screen Share" (in some versions it may be called "Cast" or "Device Connector"). Launch it. A "waiting for connection" message will appear on the screen, and the TV will become discoverable by other devices on the network.
- 📺 Press the "Home" button on the LG remote.
- 🔍 Find and launch the "Screen Share" app.
- 📡 Make sure the status is displayed as "Ready to connect".
- ⚙️ If necessary, go to the app settings and allow the connection without confirmation (to speed up the process).
It's important to note that in newer versions of webOS, this functionality may be integrated into the "Connect to Mobile Device" menu. If you don't find a separate app, try searching in the "General" or "Network" settings. Also, make sure the feature is enabled. Wi-Fi Direct active because it is often used for direct connection.
What should I do if the Screen Share app is not found?
On some LG models, this feature is built into the system and doesn't have a separate app. Try simply searching for devices on your PC. If that doesn't help, check the list of apps in the LG Content Store—the component may need to be activated or updated.
Connecting a laptop to Windows 10 and 11
Windows 10 and 11 operating systems have a built-in tool for wirelessly connecting to displays, eliminating the need for additional software. To get started, press the following key combination. Win + K on your laptop's keyboard. This will open the "Connect" sidebar, which will search for available devices.
Your LG TV's name should appear in the list of available displays. Click on it. The system will attempt to establish a connection. A confirmation message may appear on the TV screen. Use your remote to select "Accept" or "Allow." Your laptop's desktop image will then appear on the big screen.
☑️ Windows connection algorithm
If the automatic search doesn't yield any results, you can use the system settings. Go to the Start menu, select Settings (the gear icon), then System, and then the Projecting to this PC tab. Here, you need to check whether the wireless display components are installed. If the feature doesn't work, it's possible that your graphics card driver doesn't support the technology. WiDi (Intel Wireless Display).
| Parameter | Description | Recommended value |
|---|---|---|
| Projection | Permission to connect | Available everywhere on secure networks |
| PIN code | Code requirement for pairing | First time only or Always |
| Detection | Visibility for other devices | Included |
Once successfully connected, you can control the display mode. Click Win + Pto choose between "Duplicate" (a copy of your screen), "Extend" (a second desktop), or "Second Screen Only" (the laptop screen goes blank). For watching movies, the duplicate or second-screen-only mode is best.
Using the LG TV Plus app and other utilities
In cases where standard Windows tools are unstable or advanced management functionality is required, you can use the official application LG TV PlusIt's available for download in the Microsoft Store. This software not only allows you to mirror your screen, but also use your smartphone or PC as a remote control and stream media files.
To use the app, you need to pair it. Launch the program on your laptop and follow the on-screen instructions. Typically, you'll need to enter the code displayed on the TV or confirm the connection by pressing a button on the remote. The app automatically detects LG TVs on your local network.

- 🔗 Launch the app and click "Connect to TV".
- 📺 Enter the PIN code that appears on the TV screen.
- 🎬 Use the "Screen Share" feature within the broadcast app.
An alternative could be third-party programs such as LetsView or AirPlay (for Mac users). They often offer more flexible quality and latency settings. However, it's worth remembering that using third-party software may require installing a client component on the TV, if the model supports it.
⚠️ Note: When using third-party streaming apps, ensure you download them from the developers' official websites to avoid malware. App interfaces may change with the release of new versions.
Broadcast via browser and DLNA servers
If your goal is not to duplicate your desktop, but to view a specific video file, photo or music, the most effective method would be to use technology DLNAIt allows media content to be streamed directly, without burdening the processor with real-time video encoding. The LG TV acts as a renderer, and the laptop acts as a server.
In Windows 10 and 11, the media server feature is built into the system. You need to open "Media Streaming Settings" in Control Panel and allow access for your TV. Then, open a video file on your computer, right-click it, and select "Cast to Device," selecting your LG TV.
Why is DLNA better for 4K video?
The DLNA protocol streams files directly, while Miracast encodes the video stream on the fly. For large 4K files, encoding can cause jerkiness, so DLNA provides smoother playback.
Many modern browsers (Chrome, Edge) also have a built-in Cast feature. After opening a video in your browser, click the three dots in the menu and select "Cast." Select your TV from the list of devices. This is a convenient way to show a presentation or video from a website without using system settings.
For advanced users, there is the option to deploy a full-fledged media server, for example, Plex or EmbyThese programs scan your laptop's file library, automatically find metadata (covers, descriptions), and present them on your TV in a beautiful interface similar to an online cinema.
Solving common problems and delays
Despite the ease of setup, users may encounter a number of issues. The most common is that the TV isn't visible in the list of available devices. In this case, try rebooting the router, as the network table cache may be full. Also, check whether your antivirus software or Windows Firewall is blocking the connection to public networks.
Another common issue is audio and video desync or low frame rate. This is often due to a congested Wi-Fi channel. If your router operates on the 2.4 GHz band, try switching your devices to the 5 GHz band, which has less interference and higher throughput. The distance between the router and your devices also plays a role.
- 🔄 Restart the router and both devices (TV and PC).
- 📶 Switch Wi-Fi to 5 GHz.
- 🛡️ Check your Windows Firewall settings.
- 🔌 Disable the VPN if it is active on your laptop.
⚠️ Note: If you're using a corporate network or a network with a complex structure (multiple access points), discovery protocols (SSDP) may be blocked by the network administrator. Such restrictions are rare in home environments.
If your connection is constantly dropping, update your laptop's wireless adapter drivers. Visit the laptop or chipset manufacturer's website (Intel, Realtek) and download the latest driver. Older drivers may not work correctly with the new WPA3 encryption standards.
