Modern multimedia systems allow you to transform your living room into a full-fledged entertainment center, and pairing a Huawei smartphone with an LG TV is one of the most popular configurations on the market. Users often wonder how to display high-quality images on a large screen without unnecessary wires, relying solely on wireless networking. Wireless connection Provides freedom of movement and allows you to display content from any corner of the room, which is especially convenient when watching videos or giving presentations.
The process of synchronizing devices is based on several data transfer standards, such as Miracast, DLNA and proprietary protocols from manufacturers. For LG device owners, the webOS platform, which has built-in support for most popular streaming formats, often becomes a key tool. Meanwhile, Huawei smartphones running EMUI offer their own screen projection utilities, which can conflict with or, conversely, complement the standard features.
In this article, we'll cover all possible connection methods in detail, paying special attention to router settings and network security. You'll learn how to avoid image lag, which apps are best for streaming, and what to do if the automatic device search fails. Connection stability depends directly on the correct configuration of both gadgets, so it is important to follow the sequence of actions.
Preparing equipment and setting up the network
Before starting the pairing procedure, you must ensure that both devices are in good working order and have the latest software versions. Router The router must operate normally, supporting Wi-Fi standards 802.11n or higher, as older protocols may not provide sufficient throughput for high-definition video transmission. It is recommended to place the router in a visible location, minimizing the number of physical obstacles between it and the connected devices.
A mandatory requirement is that the smartphone and TV be on the same subnet. This means they must be connected to the same SSID (network name), even if the router broadcasts multiple frequency bands. Modern routers often use this technology. Smart Connect, combining the 2.4 GHz and 5 GHz bands under one name, which simplifies the task, but sometimes requires manual separation of networks for stable operation of discovery protocols.
⚠️ Note: If your router uses Client Isolation mode, devices will not be able to "see" each other on the local network. This mode is often enabled on guest networks or corporate Wi-Fi access points.
Check that Wi-Fi is enabled on both devices. On LG TVs, this can be done using the remote control by pressing the settings button or selecting the appropriate option in the menu. On Huawei smartphones, simply pull down the notification shade and enable wireless modules. Make sure that the TV is set to allow discovery of external devices, as this feature may be restricted by default for security reasons.
Using Screen Share on an LG TV
The primary tool for receiving a signal on LG TVs is a built-in feature, which may have different names depending on the webOS operating system version. On most models, you need to go to the app launcher menu and find the icon labeled Screen Share or "Connect to a mobile device." Launching this app puts the TV into connection standby mode, making it visible to external signal sources.
After activating standby mode, your TV may prompt you to confirm the connection or enter a PIN. This is a security measure to prevent unauthorized access to your screen in a crowded broadcast environment. The webOS interface typically prompts you to select the type of device you plan to connect: smartphone, tablet, or laptop, although in most cases, the system automatically detects the incoming signal type. Miracast.
- 📺 Press the Home button on the remote and find the Screen Share app.
- 📡 Make sure that the "Mobile TV On" feature or a similar option in the general settings menu is enabled in your TV settings.
- 🔒 If you're asked for a PIN, enter it on your smartphone or confirm that the numbers on both screens match.
- ⏳ Wait until your smartphone's name appears in the list of available devices on the TV screen.
It is important to note that in some older LG TV models the function may be called Smart Share, which has a slightly different interface but a similar operating principle. If automatic search doesn't produce results, try restarting the app on your TV without completely turning off the device, just closing the program. This often helps reset frozen discovery services.
Why is my TV not visible in the list?
Often, the problem is that the TV is in Hotel Mode or has limited network access rights. The signal may also be blocked by the router's antivirus software if the local network intrusion protection feature is enabled.
Mirroring your Huawei screen using your smartphone's menu
On a Huawei smartphone, the process is initiated through the system menu, which may be called "Projection," "Wireless Projection," or "Cast" in different EMUI versions. To access this function, you can usually pull down the top control menu and find the corresponding icon. If there's no standard icon, you can add one through the quick access editing menu, which is a standard procedure for customizing the interface.
After enabling the search function, the smartphone will begin scanning the air for compatible devices that support the protocol. MiracastOnce your LG TV appears in the list, click on its name. The system will establish a direct Wi-Fi Direct connection or connect via a router, depending on the selected method and network settings. Picture quality will depend on channel congestion and the distance between the devices.
Path to settings: Settings → Device connections → Screen projectionDuring operation, situations may arise where the image is transmitted with lag or artifacts. This is often due to the smartphone attempting to transmit content at a resolution exceeding the TV's decoder capabilities, or vice versa. In the projection settings on your Huawei, you can try changing the resolution or frame rate, if this option is available in the advanced settings.
☑️ Pre-broadcast check
Using the LG ThinQ app to control
An alternative and often more stable way of interaction is to use the official application LG ThinQ, which is available for download from the Huawei AppGallery or through third-party sources. This software not only allows you to mirror your screen but also use your smartphone as a remote control, expanding the functionality of the bundle. The app requires an LG account, which is a prerequisite for using cloud services.
After installation and login, the app will automatically scan the network and prompt you to add the detected TV. The pairing process is accompanied by a confirmation code appearing on the TV screen, which you must enter in the app. This ensures that you are connecting to your device and not to a neighboring TV of the same brand. After successful registration, a "Screen Casting" button or similar will appear in the control menu.
| Function | Description | Requirements |
|---|---|---|
| Photo/video projection | Transferring a media library from the gallery | Access to files |
| Cursor control | Using your phone as a touchpad | Installed application |
| Screencasting | Complete duplication of the interface | Stable Wi-Fi |
| Remote control | Replacing the physical remote control | Bluetooth or Wi-Fi |
The advantage of using LG ThinQ The app's ability to run in the background is a plus. You can minimize the app or even exit it while continuing to play videos or music on your TV, whereas standard screen projection often requires a constantly active window. Additionally, the app handles audio encoding better, reducing the likelihood of audio and video streams becoming out of sync.
⚠️ Please note: LG ThinQ app functionality may vary depending on the TV's year of manufacture and webOS operating system version. Some older models may only support basic control functions.
Broadcasting via AirPlay 2 protocol
Owners of newer LG TV models (starting from 2019) can take advantage of built-in support for the technology AirPlay 2, which was originally developed for the Apple ecosystem but is now available on Android devices via third-party apps or system functions. For Huawei, this means the ability to use native casting features if they support AirPlay, or install additional launchers that emulate this environment.
However, the most reliable way to use AirPlay on a Huawei-LG pair is to use third-party repeater apps such as Replica or AirScreen, installed directly on your LG TV via the LG Content Store. These apps create a virtual receiver on the TV that "masquerades" as an Apple device, allowing the Huawei smartphone to transmit a signal via standard AirPlay, if the system supports it, or through emulation.
If your LG TV supports AirPlay 2 natively, a corresponding icon will appear in the Input menu. When you select this source, the TV will prompt you for a connection code. On a Huawei smartphone, open the "Projection" menu, select your TV from the list, and then enter the code. This method often provides lower latency than classic Miracast, as it uses more efficient compression algorithms.
Troubleshooting connection and latency issues
Despite its apparent simplicity, a wireless connection is susceptible to numerous environmental factors. If you're experiencing constant connection drops or poor image quality, the first step is to analyze the wireless channel load. In apartment buildings, the 2.4 GHz band is often overloaded with signals from neighboring routers, leading to interference and packet loss during streaming.
Try switching both devices to the 5 GHz band if your router and TV support it. This will significantly increase bandwidth and reduce noise. It's also worth checking whether your router has any speed limits for certain devices or whether the Wi-Fi module's power-saving mode is enabled, which could reduce signal strength when idle.
- 🔄 Reboot your router by turning off the power for 10-15 seconds to clear the cache.
- 📶 Move closer to the router to eliminate the influence of physical obstacles.
- 🛡️ Disable the VPN on your smartphone, as it may redirect traffic through external servers, blocking local discovery.
- 📲 Close background apps on your phone that consume traffic (torrents, downloads).
In some cases, the problem may lie in the firewall or antivirus settings installed on the router or in the client app on the smartphone. Blocking ports used by DLNA or Miracast protocols prevents a handshake between devices. Temporarily disabling the protection will help diagnose the problem.
⚠️ Please note: Menu interfaces and item names may differ depending on your TV's firmware version and smartphone model. Manufacturers regularly update their software, changing the logic of how features work.
