Modern Smart TVs LG have become powerful multimedia centers that allow you to display content from external devices without using cables. Wireless broadcasting Mirroring images from a laptop screen to a larger display has become the standard for watching movies, presentations, or playing games. Users often look for ways to eliminate unnecessary cables, and WiFi technology is a key enabler. The setup process may vary depending on your computer's operating system and TV software version.
There are several main protocols that TVs support. LG at the base webOS. The most common is the standard Miracast, which allows screen duplication in real time. The technology is also widely used DLNA for transferring media files and protocol AirPlay 2 for Apple devices. In this article, we'll cover each method in detail, address potential connection issues, and offer optimal solutions for different use cases.
Before you begin setting up, make sure your router is working properly. Connection stability Directly impacts image quality and latency. If you plan to stream high-resolution 4K video, your WiFi channel bandwidth must be sufficient. In some cases, using the 5 GHz frequency can significantly improve performance compared to the traditional 2.4 GHz band.
Checking compatibility and preparing equipment
The first step is to verify the technical specifications of your devices. Not all laptop and TV models support the same data transfer standards. wireless connection Both devices must be on the same local network. This means the laptop and TV LG must be connected to the same router. If you have a dual-band router, make sure the devices are connected to the same frequency, although modern routers often group networks under a single name.
Televisions LG with the operating system webOS Versions 3.0 and above have built-in support for Miracast technology, which may be called "Screen Share" or "Screen Casting" in the menu. Newer models released after 2018-2019 also support AirPlay 2, which is critical for MacBook owners. On laptops running Windows 10 and Windows 11, wireless display functionality is built into the system but requires a compatible WiFi adapter.
⚠️ Note: If your router is configured with AP Isolation, devices will not see each other on the network. This feature is often enabled on guest networks or corporate segments for security reasons.
Check the software version on your TV. Manufacturers regularly release updates that add support for new codecs and protocols. Go to the settings menu and select All settings, then General And About TV. Click the button Checking for updatesto make sure you have the latest version installed firmwareOutdated software can cause instability or missing features.
Using the built-in Screen Share (Miracast) feature
The easiest way to stream an image is to use the native function MiracastOn TV LG This feature is activated through the app. Screen Share or Screencasting, which is usually found on the home screen or in the app list. After launching the app, the TV enters connection standby mode and displays the device name, which will be visible in the list of available networks on your computer.
On a laptop running Windows 10 or 11, the connection process is extremely simple. Press the key combination Win + K on the keyboard. The "Connection" panel will appear on the right, where the system will begin searching for available wireless displays. Find your TV's name in the list. LG and click on it. The system will automatically establish a connection, and the desktop image will appear on the large screen.

- ✅ Accept the connection request if it appears on the TV screen.
It's important to note that Miracast technology creates a direct WiFi connection (WiFi Direct) between devices, although the control connection goes through the router. This may result in slight delays, noticeable in fast-paced games, but quite acceptable for watching videos or working with documents. If you're using a laptop with Windows 7 or an older version, there may not be built-in support and you will need to install third-party drivers or software.
Streaming via the LG TV Plus app and DLNA
If you don't need to duplicate the screen, but rather play specific video files, photos, or music stored on your laptop's hard drive, it's better to use the protocol DLNA. Televisions LG Works perfectly with this standard. You can use the official app to manage content. LG TV Plus (formerly known as LG Smart View) for Windows or macOS, which is available as a free download from the manufacturer's official website.
After installing the app and connecting to the same WiFi network, it will automatically detect a compatible TV. You can select files to play directly from the app interface, control the volume, and even use your smartphone or laptop as a remote control. Unlike Miracast, the video decoding load is transferred to the TV's processor, freeing up your laptop's resources.
An alternative method is to use Windows' built-in tools. Open File Explorer, find the video file you want, right-click it, and select Transfer to deviceIn the list that appears, select your TV. LGThe media player will open a playback window, and the file will begin streaming to the TV screen. This method is ideal for watching high-quality movies without the compression artifacts typical of screen mirroring.
| Method | Best use | Image quality | Delay |
|---|---|---|---|
| Miracast | Presentations, browser, photos | Depends on the signal | Average |
| DLNA | Movies, music, photos | Original (no loss) | Low |
| AirPlay 2 | Apple device content | High | Low |
| HDMI cable | Games, 4K HDR content | Maximum | Absent |
Connecting MacBook and Apple devices (AirPlay 2)
For laptop owners MacBook I was the luckiest one, because modern TVs LG support technology AirPlay 2 At the hardware level, this allows you to stream videos, photos, and even your entire Mac screen to your TV with minimal latency and high quality. This feature doesn't require any additional apps to be installed on your TV; your TV model must support this standard (usually 2019 models and newer).
To start streaming, make sure your MacBook and TV are connected to the same WiFi network. In the Mac's control panel (upper right corner), find the Control center (two switched lines) and select Screen mirroringYour TV should appear in the list of available devices. LGWhen you connect for the first time, you may see a message on your TV screen. confirmation code, which needs to be entered on the laptop.
⚠️ Note: AirPlay may be disabled by default on LG TVs. Check your privacy settings in the TV menu:

However, it's important to remember that most advanced features in such programs are paid or have limitations in the free version. Using third-party software also increases the load on the laptop's processor.
☑️ Diagnosing connection issues
Troubleshooting and quality adjustment
Even with proper setup, technical difficulties can arise. The most common issue is that the laptop doesn't detect the TV. In 90% of cases, this can be resolved by ensuring both devices are on the same subnet. Sometimes routers distribute the 2.4 GHz and 5 GHz frequencies as separate networks (for example, MyWiFi And MyWiFi_5G). Make sure that the laptop and TV are connected to the same network name.
The second common problem is desynchronization of audio and video, or a choppy picture. This indicates insufficient WiFi bandwidth. Try lowering the resolution of the streaming image in the Windows connection settings (click Win + P, then projector settings). Disabling other devices that actively consume bandwidth, such as torrents or online games on other devices, may also help.
If the problem persists, try resetting the network settings on your TV. Go to Settings → Network → WiFi Connection, select your network and press Modified/Disabled, then reconnect. On a Windows laptop, you can try resetting the TCP/IP stack via the command prompt with administrator rights by running the following command:
netsh winsock resetAfter running the command, be sure to restart your computer. Also, make sure your laptop's WiFi adapter drivers are updated to the latest version, as manufacturers frequently release patches to improve connection stability with multimedia devices.
Comparison of methods and final recommendations
Choosing the optimal broadcasting method depends on your specific needs. For business presentations and software demonstrations, it's best suited Miracast or a built-in Windows feature, as they provide interactivity. To view downloaded movies in high quality, it is preferable to use DLNA or connect your laptop with an HDMI cable to avoid image compression.
Users of the Apple ecosystem should rely on AirPlay 2, which provides the best integration and convenience. If none of the standard methods work satisfactorily, third-party intermediary applications are always an option, although they may introduce additional latency. The main thing is to ensure a high-quality network environment.
⚠️ Please note: The LG TV menu interface (webOS) may vary depending on the model year and firmware version. The location of settings items may be changed by the manufacturer.
In conclusion, wireless connection between laptop and TV LG Opens up a wide range of possibilities for enjoying home media content. Proper network setup and understanding the differences between data transfer protocols will allow you to enjoy content on the big screen without unnecessary wires and complications.
Why isn't my LG TV showing up in the list of available 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 the signal receiving app (Screen Share) is running on the TV if manual confirmation is required.
Is it possible to broadcast audio separately, without video?
Yes, when using the DLNA protocol or remote apps (LG TV Plus), you can only play the audio stream. When mirroring your screen (Miracast/AirPlay), the audio is transmitted along with the image, but you can disable it on the TV itself, leaving it running on your laptop, or vice versa, by changing the audio output device in your system.
Does broadcasting affect internet speed?
When using Miracast and AirPlay (screen mirroring), you may not use any internet connection at all, as data is transferred directly between devices over the local network. However, if you're streaming online video (for example, YouTube from a browser), your data usage will be normal.
How to improve picture quality during wireless broadcasting?
Use a router that supports WiFi 5 (AC) or WiFi 6 (AX) and connect devices to the 5 GHz band. Avoid physical obstructions between the router and devices. For critical image quality, an HDMI cable is still recommended.
