Modern technologies make it possible to transform any Smart TV into a full-fledged multimedia center without the use of unnecessary cables. Equipment owners LG often face the need to broadcast the contents of a laptop screen to a larger screen for watching movies, presentations, or games. Wireless connection via WiFi Provides sufficient bandwidth to transmit high-quality images, freeing the user from the tangled HDMI cables.
The process of synchronizing devices is based on standards Miracast And DLNA, which are built into Windows and macOS operating systems. However, despite their apparent simplicity, users may encounter device visibility issues or image lag. Proper network configuration and selection of the appropriate protocol can ensure a stable image with minimal input lag.
In this article, we'll take a detailed look at all the connection methods available in 2026 and explore the nuances of working with different operating systems. You'll learn how to set up LG Screen Share, use third-party apps, and optimize your network for optimal data transfer. It's important to understand that connection quality directly depends on the speed of your router and its location relative to the receiver.
Wireless video transmission technologies: Miracast and DLNA
Before you begin setting up, it's important to understand the basic technologies that enable streaming. The primary standard for screen mirroring is MiracastThis technology allows for real-time video and audio transmission without compression, which is critical for demonstrating presentations or playing games. In televisions LG This function is often labeled as Screen Share or Smart View.
The second popular standard is DLNAUnlike Miracast, it doesn't broadcast the entire desktop in real time, but allows you to open media files (videos, photos, music) on your TV, controlling the process from your laptop. This is convenient for watching downloaded movies, but not suitable for sharing a browser or working with documents. Modern Smart TVs support both protocols, switching between them automatically depending on the task.
⚠️ Important: Miracast and DLNA protocols work on a local network. Make sure your laptop and TV are connected to the same router, even if one uses a wired connection and the other uses WiFi.
There is also technology Apple AirPlay 2, which is integrated into many new LG TV models. It provides the best connection quality for macOS and iOS devices. For Windows laptops, AirPlay is only available through third-party emulators, which can reduce performance.
Preparing equipment and setting up the network
Successful synchronization is impossible without proper infrastructure preparation. The first step is checking device compatibility and updating the software. For TV owners LG On webOS, you need to make sure that the signal reception function is activated in the system. To do this, go to the settings menu and select General → Connection Manager → Connect to a mobile device.
The quality of your wireless network plays a crucial role. If your router supports dual-band, it's recommended to use the frequency 5 GHzThis band provides higher data transfer rates, which is critical for 4K video, but has a shorter range than 2.4 GHz. Make sure both devices are within a strong signal range.
To activate visibility mode on your LG TV, follow these steps:
- 📺 Click the button
InputorSettingson the remote control. - 📡 Select an app Screen Share or find the corresponding item in the start menu.
- 🔒 If confirmation is required, allow the connection on the TV screen when prompted.
Once the TV enters standby mode, it begins broadcasting its ID to the network, making it visible to external devices. At this point, you can proceed to setting up the laptop itself.
Streaming from a laptop to Windows 10 and 11
Microsoft operating systems have built-in support for Miracast technology, making the connection process extremely simple. You don't need to install any additional software. To get started, make sure the WiFi module is enabled, even if your laptop is connected to the internet via a cable.
Algorithm of actions for activating the projection:
- 💻 Press the key combination
Win + Kon the keyboard or go toSettings → System → Display. - 🔍 At the bottom of the window, click the button Connect to a wireless display.
- 📡 Find your TV in the list of available devices LG and select it.
The system will attempt to establish a connection. Once paired successfully, your laptop screen will be mirrored on the TV. You can change the projection mode by pressing Win + POptions available: second screen only, duplicate, extend, or computer screen only.
☑️ Windows Connection Checklist
If the system reports that the device is not found, check your WiFi adapter drivers. Laptop manufacturers sometimes disable Wi-Fi Direct to save power. Find your wireless adapter in Device Manager, go to Properties, and ensure that the power plan prevents it from being turned off.
Connecting MacBook and Apple devices (AirPlay)
Laptop owners MacBook have the advantage of native technology support AirPlay 2 on modern LG TVs. This provides a more stable connection and high-resolution support compared to Miracast. However, this feature is only available on LG models released after 2018 and supporting webOS 4.0 or higher.
To start a broadcast, follow these steps:
- 🍏 Make sure your MacBook and TV are on the same WiFi network.
- 🖥️ Click on the icon Control center in the menu bar (two switches) or use the button

When you first connect, a four-digit code may appear on your TV screen. Enter it on your MacBook to confirm it's a trusted device. Subsequently, whenever you're on your home network, the connection will be established automatically.
⚠️ Please note: Operating system and TV interfaces are subject to update. Button locations and menu item names may differ from those described in the instructions. Always consult the manufacturer's latest manuals.
What to do if AirPlay doesn't work on an old LG TV?
If your TV model doesn't natively support AirPlay 2, you can use third-party emulator apps available in the LG Content Store, such as AirBeam or TV Assist. These create a software bridge between Apple and DLNA/Miracast protocols, allowing you to stream images, although latency may be slightly higher than with a native connection.
Using Google Chrome Browser for Broadcasting
If standard methods don't work or you only need to broadcast a browser tab, the built-in function is a great solution Google CastThis method is universal and works on Windows, macOS, and Linux. It's especially convenient for presenting web content, YouTube, or Google Slides.
