Modern Honor smartphones offer powerful multimedia capabilities, but sometimes the screen size isn't large enough to comfortably view movies or photos. LG Smart TV owners often need to display content from their mobile device on a larger screen without the hassle of cables. Fortunately, wireless data transfer technologies make this possible quickly and efficiently, using only your home Wi-Fi network.
The connection process depends on the version of the Magic UI or Android operating system, as well as the year of your LG TV. There are various video transmission protocols, such as Miracast, AirPlay 2 and proprietary solutions from LG. Understanding how these technologies work will help you choose the most appropriate method and avoid common setup mistakes.
In this article, we'll take a detailed look at all available device synchronization methods. You'll learn how to set up a wireless monitor, use multimedia features, and troubleshoot potential connection issues. The key requirements for a successful operation are stable router operation and correct settings for both devices.
The key condition for most methods to work is that the Honor smartphone and LG TV are on the same Wi-Fi subnet. If your router is sharing a guest network or using AP Isolation, you won't be able to connect until you change your router settings.
Equipment preparation and basic requirements
Before setting up, make sure your equipment meets the minimum technical requirements. Older router models may not support the necessary protocols for transmitting high-definition video streams. It's also important to ensure that the software on both devices is updated to the latest version.
Make sure your LG Smart TV has the operating system installed. webOS Version 3.0 or higher is recommended, as older versions may not support modern wireless broadcasting standards. For Honor smartphones, Android 6.0 or higher is recommended, although modern models with Magic UI offer significantly more stable operation.
Check your internet connection speed and signal stability. Streaming 4K video requires high bandwidth. If the router is located far from your TV or phone, image quality may degrade and the video may flicker.
- 📡 Make sure both devices are connected to the same Wi-Fi network (2.4 GHz or 5 GHz).
- 🔄 Check for firmware updates in your LG TV's settings menu.
- 📱 On your Honor phone, enable wireless communication and Bluetooth for discovery.
- 🔌 Make sure Smart Share or a similar feature is activated in your TV settings.
⚠️ Attention: Some corporate or public Wi-Fi networks may block direct connections between devices (P2P). In these cases, wireless streaming will not work, even if both devices are connected to the same access point.
If you use a dual-band router, try connecting both devices to the 5 GHz network. This will ensure faster data transfer rates and lower latency. However, keep in mind that the 5 GHz band has a smaller coverage area than the 2.4 GHz band.
Using the built-in Wireless Monitor feature
The most common and universal screen sharing method is using Miracast technology, often referred to as "Wireless Monitor" or "Cast" in Honor phones. LG TVs support this standard natively, so installing additional software is usually not required.
To get started, pull down the notification shade on your Honor smartphone and look for the "Broadcast" or "Wireless Projection" icon. If the icon isn't in the quick menu, go to Settings → Other Connections → Wireless MonitorThe phone will start searching for available devices within the network range.
On your LG TV, you may need to launch the "Screen Share" or "Smartphone Display" app. On newer webOS models, this feature is often integrated into the source selection menu and launches automatically when prompted by a mobile device. On older models, you'll need to find the app in the list of installed apps.
☑️ Checking connection readiness
Once your TV is listed on your smartphone screen, simply tap its name. A connection request will appear on the TV screen, which you'll need to confirm with your remote control. After this, the image from your Honor phone will be fully mirrored on the LG Smart TV screen.
It's important to note that when using this method, your phone and TV screens are fully synchronized. This means notifications, incoming calls, and system sounds will be broadcast to the big screen. For a comfortable movie viewing experience, it's recommended to enable "Do Not Disturb" mode.
- 🖥️ Image quality automatically adapts to network capabilities.
- 🔊 The sound is also transmitted through the TV speakers.
- 🎮 Input lag may be noticeable when playing games, but is unnoticeable when watching videos.
⚠️ Attention: The Magic UI and webOS interfaces may be updated periodically. The location of menu items or function names may differ from those described in the instructions. If you can't find the item you need, use the search in your device settings.
If the connection drops immediately after setup, try rebooting your router. Often, the problem lies in a router buffer overflow or an IP address conflict on the local network. A static IP address for your TV can help stabilize the connection.
AirPlay 2 streaming on new LG models
Owners of modern LG TVs (2019 models and newer) can use the protocol AirPlay 2Although this is an Apple development, many Honor smartphones, especially newer models, have built-in support for this standard or allow it to be emulated through third-party applications.
The main advantage of AirPlay 2 is its support for multi-room audio and a more stable connection. The protocol offers lower latency and better picture quality compared to classic Miracast. It also allows you to use your phone for other tasks while watching video on your TV.
To check support, go to the LG TV settings section Support → AirPlay and HomeKitMake sure the feature is enabled. On your Honor phone, open the Control Panel and select "Screen Mirroring," or use the casting feature in the YouTube app by selecting the AirPlay icon.
What to do if AirPlay is not found?
If your Honor phone can't see your TV via AirPlay, make sure Bluetooth is enabled on both devices. The protocol uses Bluetooth for the initial handshake before switching to Wi-Fi Direct. Also, check if your router's firewall is blocking the ports used by the Bonjour protocol (5353 UDP).
When you first connect, a code may appear on your TV screen that you must enter on your smartphone. This is a security measure to prevent unauthorized access to your screen. Once the devices are successfully paired, reconnection will occur automatically.
Using AirPlay 2 is especially useful if you plan to stream content from apps optimized for this protocol. In this case, playback controls (pause, rewind) are controlled directly from your phone, without interrupting the stream.
- 🍏 Support for high-quality audio and video without compression.
- 📱 Possibility to lock your phone screen while watching.
- 🏠 Integration with HomeKit smart home (for Apple ecosystem users).
It's worth noting that not all Android apps support direct AirPlay output. In such cases, you'll have to use full screen mirroring, which drains your smartphone's battery.
LG TV Plus and Smart Share app
Official app LG TV Plus (or its newer version, LG ThinQ) offers advanced TV control and media streaming capabilities. Available for download from the Google Play Store, this software turns your smartphone into a powerful remote control.
To get started, install the app on your Honor phone and run a device scan. The app will find your LG TV on your local network. Once paired, you'll have access to your phone's photo and video gallery, with the option to display them on the big screen.
Unlike mirroring, Smart Share only allows you to transfer specific files. You can select a video file from your gallery, click the "Stream" button, and select the target device. The TV will open its built-in player and begin playing the file.
| Function | Screen mirroring | Smart Share / Cast | LG TV Plus |
|---|---|---|---|
| Transmission type | Full Screen (Live) | Media files | Management and media |
| Phone addiction | High (screen active) | Low (background) | Average |
| Battery consumption | High | Short | Average |
| Picture quality | Depends on the signal | Original | Original |
Using the official LG app guarantees maximum compatibility and stability. The developers regularly release updates that fix bugs and add support for new file formats.
If the default app doesn't work or seems inconvenient, you can consider alternatives from the app store. However, third-party apps often contain ads or have limitations in the free version, so the official solution from the TV manufacturer remains the preferred choice.
Streaming content from browsers and applications
Most modern video viewing apps, such as YouTube, Netflix, IVI, or Okko, have a built-in Cast feature. This allows you to stream video directly from the provider's servers to your TV, bypassing the smartphone's processor.
To use this feature, open the desired app on your Honor phone and look for the cast icon (a rectangle with waves in the corner). It's usually located in the upper right corner of the player. Tap it and select your LG TV from the list.
The advantage of this method is that the phone acts only as a remote control. You can minimize an app, answer a call, or even turn off the smartphone screen, and playback on the TV will not be interrupted.
Google Chrome also offers a tab casting feature. Open the browser menu (three dots), select "Cast," and choose a source: a tab or the entire screen. This is a convenient way to show a presentation or webpage on a larger screen.
- 🌐 Traffic is consumed directly by the TV (during streaming).
- 🔋 Save your smartphone's battery life.
- 🎬 Support for 4K and HDR quality without putting a strain on your phone.
⚠️ Attention: Some apps may block the output of protected content (DRM) over wireless protocols if the connection is unsecured. In this case, a black screen may appear even though the audio is working.
It's important to keep up to date with the latest versions of the YouTube app and other services. Outdated versions may not support the new communication protocols used by LG TVs. Regularly updating your apps in Google Play is key to ensuring stable operation.
Solution and troubleshooting
Despite the simplicity of the technology, users may encounter connection issues. The TV may not detect the phone, the image may lag, or there may be no sound. Most of these issues can be resolved with basic network diagnostics.
If devices can't find each other, first check if client isolation is enabled on your router. This feature is designed for security in public areas and prevents devices on the same network from exchanging data. For a home network, it should be disabled.
A common cause of problems is an overflowing app cache or a temporary glitch in the Wi-Fi modules. Try a hard reset of both devices: unplug the TV for 10 seconds and then reboot your smartphone. This will reset the temporary network settings.
To improve video transmission quality, we recommend disabling Wi-Fi power-saving mode on your router. You can also try manually entering DNS servers (for example, Google's: 8.8.8.8) in your TV's network settings; this can sometimes improve response times.
In rare cases, the issue may be related to the antivirus software or firewall installed on your Honor smartphone. Try temporarily disabling the protection and see if your device appears in the list of available devices for streaming.
- 🔄 Reset the network settings on your TV (Network → Reset Wi-Fi).
- 📡 Reboot your router.
- 📱 Delete and re-add the Wi-Fi network on your phone.
- 🛡️ Check permissions for streaming apps.
If all else fails, update your TV's firmware via a USB drive, downloading the latest version from the official LG website. Sometimes software bugs in older versions of webOS block Miracast protocols.
Frequently Asked Questions (FAQ)
Is it possible to connect an Honor phone to an LG TV without Wi-Fi?
Yes, this is possible with a cable. For modern Honor smartphones with a USB Type-C port, you'll need a USB-C to HDMI adapter. However, your TV must support MHL or HDMI-CEC technology for control transfer. It's important to note that not all Honor models support video output via the charging port; please check the specifications for your specific phone model.
Why is there no sound when broadcasting video?
Most often, the problem lies with the volume settings or the audio output device selected. Check that the volume on the TV itself isn't turned down. Also, in some apps (such as YouTube), you need to manually switch the sound to the TV after starting the broadcast. If the problem persists, try restarting the app.
Does phone connection affect internet speed?
When using screen mirroring (Miracast), the internet may not be used at all, as a direct connection is created between devices. However, when streaming online video (YouTube, Netflix), the traffic goes through the router. If the bandwidth is limited, the video quality may automatically be reduced to SD to compensate.
Will the broadcast work if the phone battery runs out?
No, turning off your phone or putting it into sleep mode (while mirroring) will interrupt the signal transmission. The TV will display a no signal message or return to the last source. When using Cast mode (within apps), some services allow you to continue watching from the same point on another device, but the streaming itself will stop.
