Wireless data transfer technology eliminates the need to search for adapters and tangled cables, making the process simple and fast.
There are several proven methods for projecting from a phone to an LG TV, and the specific method you choose depends on your device's operating system. Android device owners can use the built-in function Miracast or a branded application LG TV Plus, while iOS users rely on technology AirPlay 2It's important that both devices are on the same local network, as the router acts as an intermediary transmitting the video stream.
In this article, we'll cover all current connection methods in detail, troubleshoot common errors, and explore the nuances of working with different operating system versions. You'll learn how to adjust image and sound quality, and also understand why your phone sometimes doesn't detect your TV even when Wi-Fi is enabled. Follow our instructions to turn your TV into the center of your multimedia system.
Preparatory stage and network requirements
Before beginning the pairing process, you need to ensure your home network is ready to handle heavy video streaming. A key requirement for stable operation is that the smartphone and TV are on the same Wi-Fi subnet. This means that if the router broadcasts two networks (for example, 2.4 GHz and 5 GHz), both devices must be connected to one of them, or the router must correctly handle inter-network traffic.
To ensure high data transfer speed without delays and image artifacts, it is recommended to use the standard Wi-Fi 5 (802.11ac) or newer. Older routers that only operate in the 2.4 GHz band may not be able to handle high-definition streams, resulting in choppy images or out-of-sync audio.
⚠️ Note: If you're using a guest Wi-Fi network or AP Isolation on your router, devices may not be able to see each other. In your router settings, ensure AP Isolation is disabled for your primary network.
It's also worth checking your LG TV's firmware version. Manufacturers regularly release updates that improve the module's stability. Wi-Fi Direct and add support for new codecs. Go to your TV's settings menu and check for software updates before starting setup.
Broadcast from Android using built-in features (Screen Share)
Most modern LG TVs run on the platform webOS, which has built-in support for the technology MiracastThis allows you to mirror your smartphone's screen without installing any additional software. On your LG TV, you'll need to find the app. Screen Share (Screen Casting) in the channel list or app menu and launch it. The TV will then enter connection standby mode.
On an Android smartphone, the procedure may have different names depending on the model: "Cast," "Smart View," "Wireless Monitor," or "Screen Projection." This option is usually found in the notification shade (swipe down from the top) or in the connection settings. After scanning the network, the phone will detect your LG Smart TV.
When connecting for the first time, a confirmation request may appear on the TV screen. Use the remote control to select "Accept." From this point on, the phone's image will be mirrored on the big screen in real time. Picture quality depends on the strength of the Wi-Fi signal and the power of the phone's processor.
It's worth noting that when using Miracast, your phone continues to function normally, and all notifications will be visible on the TV. If you plan to view confidential messages, it's best to enable "Do Not Disturb" mode on your mobile device beforehand.
Using the LG TV Plus app to control
Official app LG TV Plus (formerly known as LG ThinQ or simply LG TV) offers more advanced functionality than simple screen mirroring. It is available for download at Google Play And App StoreAfter installing and launching the app, it will automatically scan the network and offer a list of available LG TVs.
The main advantage of this method is the ability to transfer files directly, without duplicating the entire phone interface. You can select a photo or video from your gallery, click the "Cast" button, and send the file to your TV. In this case, the phone acts as a remote control, and the TV decodes the video itself, reducing the strain on your smartphone's battery.
☑️ Check before connection
The app also has a feature available Magic Mobile Connection, which allows you to use your smartphone as a touchpad to control the cursor on your TV screen. This is especially convenient for entering text when searching for videos on YouTube or navigating the TV's web browser, as typing on the remote's virtual keyboard is time-consuming and cumbersome.
⚠️ Please note: The LG TV Plus app may request numerous file and location permissions. This is necessary for the local network device search feature to function correctly. However, you can always revoke these permissions in your Android settings after setup.
Connecting iPhone and iPad via AirPlay 2
Apple device owners will appreciate the technology's support AirPlay 2 in modern LG TVs. This function is built directly into the system webOS, so no third-party apps are required for connection. Simply ensure your iPhone and TV are connected to the same Wi-Fi router.
To start casting, open Control Center on your iPhone (swipe down from the upper-right corner or up from the bottom, depending on your model). Tap the Screen Mirroring icon (two rectangles) and select your LG TV from the list. If prompted, enter the code displayed on your TV screen on your mobile device.
AirPlay 2 enables high-quality video streaming, up to 4K, and supports surround sound. A key feature is the ability to use your phone while watching: you can switch to a messenger or browser, and the video streaming will not be interrupted, unlike simple screen mirroring via Miracast.
What to do if AirPlay isn't working?
Make sure AirPlay support is enabled on your TV in the settings (General → AirPlay). Also, check that your router's firewall isn't blocking the ports used by the Bonjour protocol (UDP 5353).
The system allows you to create groups of multi-room audio devices if you have multiple compatible LG speakers or TVs. This turns a regular living room into a full-fledged audio system with synchronized music playback in all rooms.
Comparison of connection methods and their features
The choice of connection method directly impacts the user experience. Each method has its own strengths and weaknesses, which should be considered depending on your needs. Below is a table to help you choose the best option.
| Method | Image quality | Latency | Battery consumption |
|---|---|---|---|
| Miracast (Screen Share) | High (depending on signal) | Average (noticeable in games) | High (encodes video) |
| LG TV Plus (Cast) | Maximum (decoding on TV) | Low | Average |
| AirPlay 2 | Maximum (4K HDR) | Minimum | Short |
| HDMI (cable) | No losses | Absent | Charging the device |
As the comparison shows, the "Cast" method via an app or AirPlay is best for watching movies, as they put less strain on the phone. However, if you need to show a presentation or photo gallery in real time, the built-in screen mirroring feature is more convenient.
The issue of format compatibility deserves special attention. With a direct connection (Cast), the TV may not support some rare video file codecs that are easily played on a phone. In this case, only full screen mirroring or using a third-party media player, such as VLC for Android, which has a built-in broadcast function.
Solution and troubleshooting
Despite the technology's refinement, users sometimes encounter connection issues. The most common is that the phone simply doesn't see the TV in the list of available devices. In 90% of cases, this can be resolved by rebooting the router, as accumulated errors in the ARP table can block the discovery of new clients.
Another common issue is connection interruptions or the "Buffering" message. This indicates insufficient bandwidth. If you have many devices connected to your Wi-Fi, try disabling downloads on other devices or moving the router closer to your TV.
⚠️ Warning: Antivirus programs or firewalls installed on your smartphone may block local connections. Try temporarily disabling network protection in your antivirus settings to check.
If the image is transmitted but there is no sound, check your audio output settings. On Android, sound should automatically go through the TV when mirroring, but sometimes you may need to manually select the output device in the volume menu. On iOS, make sure the TV is selected in Control Center, not the iPhone speaker.
Frequently Asked Questions (FAQ)
Is it possible to project a screen via Wi-Fi Direct without a router?
