Connecting a laptop to an LG TV with an operating system WebOS Wirelessly access multimedia, games, and presentations in high quality. This method is especially convenient when the device is located at a distance and HDMI ports are occupied or physically inaccessible.
The synchronization process is based on standards Miracast and DLNA, which are built into most modern Windows and macOS operating systems. You don't need to purchase additional hardware if both devices support Wi-Fi Direct. Simply configure the network settings correctly and select the appropriate display mode in the TV menu.
In this article, we'll cover all connection steps in detail, including potential issues and solutions. You'll learn how to ensure a stable high-definition signal and which router settings can affect picture quality. Follow the instructions to turn your TV into a fully functional monitor for any task.
Technical requirements and equipment preparation
Before setting up, you need to make sure your equipment meets the minimum requirements for stable wireless operation. The key requirement is a Wi-Fi module in your laptop and support for the technology on your TV. Screen Share or MiracastMost LG models released after 2014 with the webOS shell have built-in support for these standards.
It's important to understand the difference between media streaming and full screen mirroring. For the former (DLNA), all that's required is for devices to be on the same local network, even without internet access. The latter (desktop mirroring) requires a more stable connection and protocol support. Wi-Fi Direct.
⚠️ Important: If your router is configured for AP Isolation, devices will not see each other even when connected to the same network. Make sure your router settings allow data exchange between wireless clients.
It's also worth paying attention to your Windows operating system version. Older versions, such as Windows 7, may lack Miracast support or require additional drivers. In Windows 10 and 11, this feature is integrated natively and works through the Action Center.

Setting up an LG WebOS TV to receive a signal
The first step is to activate signal reception mode on the TV. The webOS interface may differ slightly depending on the firmware version, but the steps remain the same. Open the application menu and find the system utility for wireless connection.
Press the button on the remote control Home (house icon) to open the main menu. Find the icon in the bottom app bar. Screen Share or Connecting to a mobile deviceIn some firmware versions, this function may be simply called "Broadcast" or integrated into the signal source menu. Input.
After launching the app, a connection waiting window will appear on the screen. Your TV's name may be displayed here, which will be visible in the list of available devices on your computer. In newer versions of webOS, the system may request permission to connect the first time you connect from a new device.
Menu path: Settings → All settings → Connection → Connection manager → Screen ShareIt's recommended to check for TV software updates before using the TV. Manufacturers frequently release patches that improve wireless connection stability and fix Miracast protocol errors. This is especially important if you're experiencing image lag.
☑️ Checking the TV's readiness
Connecting a laptop to Windows 10 and 11
In Windows family operating systems, the connection process is implemented as simply as possible thanks to technology ConnectYou don't need to install third-party drivers if your Wi-Fi adapter supports the required standards. The process only takes a few seconds when configured correctly.
Open the action bar by pressing the key combination Win + K or the "Notifications" button in the lower right corner of the screen. Your LG TV should appear in the list of available devices that appears. If the device isn't visible, make sure the Screen Share app is open on your TV and searching for it.
After selecting the TV, the system initiates the connection. A connection confirmation prompt may appear on the TV screen; use the remote control to grant access. After this, the desktop image will be mirrored to the big screen.
| Parameter | Description | Recommended value |
|---|---|---|
| Protocol | Transmission technology | Miracast / Wi-Fi Direct |
| Permission | Maximum quality | 1920x1080 (Full HD) |
| Frequency | Personnel update | 60 Hz |
| Delay | Response time | < 100 ms |
If the connection is established but the image appears stretched or blurry, check the resolution settings in Windows. Right-click on the desktop, select Screen parameters and set the recommended resolution for your TV.
What to do if Windows doesn't see the TV?
Make sure "Projecting to this PC" is enabled in the system settings. Go to Settings → System → Projecting to this PC and set it to "Available anywhere on secure networks." You may also need to add the "Wireless Display" component via the "Manage optional components" menu.
Streaming from macOS and using AirPlay
Apple laptop owners can take advantage of the technology AirPlay 2, which is supported by many modern LG models. This ensures more stable streaming and integration with the Apple ecosystem. However, if your TV doesn't natively support AirPlay, you'll need to use third-party solutions.
To check compatibility, look for the "Screen Mirroring" icon in the macOS Control Center. If your LG TV appears in the list, simply select it. Otherwise, make sure both devices are connected to the same Wi-Fi network and AirPlay support is enabled in the TV settings.
An alternative option for older models is to use AirPlay emulator applications installed on the TV through the store. LG Content StoreApplications such as AirScreen or Receiver for AirPlay, allow you to stream images from your Mac to any Smart TV.
⚠️ Please note: When using third-party AirPlay emulator apps on webOS, increased audio and video latency may occur. This isn't a problem for watching movies, but it can be inconvenient for gaming or word processing.
Image quality in macOS depends on your wireless network bandwidth. For 4K content streaming, we recommend using routers that support the 5 GHz band. This will prevent compression artifacts and connection interruptions.
- 🍎 Open Control Center on your Mac (the toggle switch icon).
- 📡 Tap "Screen Mirroring" and select LG TV.
- ⚙️ Enter the code from the TV screen if prompted.
- 🖥️ Select "Primary display" or "Duplicate" mode.
Using DLNA for media streaming
If your goal is not to duplicate your desktop, but to view movies or photos stored on your laptop's hard drive, it is better to use the protocol DLNAThis method is less resource-intensive and provides better image quality for video files, since the TV decodes the stream itself.
In Windows 10 and 11, the media server feature is built into the default player. Open the Streaming Media app or use the file context menu. Simply right-click the video file, select Transfer to device and indicate your LG TV.
For more advanced media library management, it is recommended to install a specialized server, for example, Universal Media Server or PlexThese programs allow you to organize a library with covers, descriptions, and automatic sorting of content that will be available on your TV.
Windows menu path: Control Panel → Network and Internet → Network and Sharing Center → Streaming MediaThe advantage of DLNA is that the laptop can be locked or used for other tasks while watching. The TV reads the data directly, without requiring a constantly active player window on the computer.
Troubleshooting and connection diagnostics
Despite the simplicity of the technology, users may encounter connection issues. The most common cause is an unstable Wi-Fi signal or IP address conflict. If the image is choppy or intermittent, try moving the router closer to the TV or using a repeater.
Another common issue is antivirus software or Windows Firewall, which can block incoming connections. When you first launch the broadcast feature, the system will usually ask for network access permission—make sure you select a private network, not a public one.
If the connection is completely lost, try rebooting both devices and the router. Sometimes resetting the TV's network settings to factory defaults helps. Also, check if your router has a speed limit for wireless clients.
⚠️ Note: Interfaces and menu item names may change with webOS firmware updates. If you don't see the options described, check the official documentation for your specific model on the manufacturer's website.
If all else fails, you can try alternative methods, such as a long HDMI cable or Chromecast if your TV has one built in. However, properly configured Wi-Fi Direct remains the most convenient method for everyday use.
- 🔄 Restart your router by unplugging it from the power outlet for 10 seconds.
- 🛡️ Check your Windows Firewall settings to see if they are blocking it.
- 📶 Make sure your laptop and TV are in the same frequency range (2.4 or 5 GHz).
- 🔌 Disable VPN connections on your laptop, as they may interfere with local browsing.
Why doesn't the TV see the laptop in the list of devices?
Most often, the problem is that the devices are connected to different networks (for example, one to a guest network and the other to the main network) or client isolation is enabled on the router. Also, make sure network discovery is enabled on the laptop.
Can you play games on TV via Wi-Fi?
Technically, this is possible, but input lag can make control uncomfortable. For fast-paced shooters or racing games, an HDMI cable is better. For turn-based strategy or card games, the lag won't be a problem.
How to improve the quality of a picture if it is blurry?
Check that your TV's native resolution (usually 1920x1080 or 3840x2160) is set in Windows display settings. Also, try switching your router to the 5 GHz channel to increase bandwidth.
Does the sound work over a wireless connection?
Yes, when using Miracast or AirPlay, audio is transmitted along with video. Make sure the "LG TV" or similar output device is selected in Windows sound settings so that audio is sent through the TV speakers, not the laptop.
