Your router acts as an intermediary, creating a bridge between your mobile device and Smart TVIt's important that both devices are on the same subnet to ensure stable data transfer speeds and no lag during streaming.
In this article, we'll take a detailed look at all available synchronization methods, from built-in operating system features to specialized software. You'll learn how to set them up. Miracast protocol For screen mirroring or use DLNA to stream your media library. Properly configured network settings will ensure high-quality, tear-free images.
Preparing equipment and setting up the network
The first step to successful streaming is ensuring a stable connection between devices. Both devices must be connected to the same router, preferably using the same range. 5 GHz, which provides higher throughput compared to 2.4 GHz. This is especially critical when transmitting high-definition video. 4K.
Check your router settings: function WPS must be active for quick pairing, although manual password entry is also acceptable. Make sure that the TV LG Smart Share or a similar signal reception service, which is usually activated by default in modern models, is enabled WebOS.

LG TV Plus app for advanced control
Official app LG TV Plus (formerly known as LG TV Remote) offers a deeper level of smartphone-TV integration. It allows you to not only stream photos and videos from your gallery but also use your phone as an advanced remote control with support for text input from your smartphone's keyboard.
Download the app from Google Play or App Store and launch it. The program will automatically scan the network and find your TV. After pairing, which is confirmed by a code on the TV screen, go to the "Media" or "Gallery" section. Here you can select any files to display on the big screen.
The main advantage of this method over simple mirroring is the ability to control playback independently. You can scroll through your social media feed on your phone while a slideshow of your photos plays on your TV. The app also supports transferring files of various formats that the built-in player might not be able to read directly.
The app's interface is intuitive and divided into logical blocks. The "Display" tab lets you control image settings, while the "Remote" tab emulates all the buttons of a physical remote, including the scroll wheel. This is especially convenient if the standard remote is lost or its batteries are dead.
Comparison of data transfer methods
Choosing the optimal streaming method depends on your specific needs: whether you simply need to share a photo with friends, stream a movie from an online cinema, or showcase a work project. Each method has its own technical features and limitations.
The table below provides a comparison of the key features of the various protocols and applications available to equipment owners. LGThis will help you quickly navigate and choose the most suitable option for your situation.
| Method | Transmission type | Quality | Delay |
|---|---|---|---|
| Screen Share (Miracast) | Mirroring | High | Average |
| AirPlay 2 | Mirroring / Streaming | Very high | Low |
| LG TV Plus | Media files | Original | Absent |
| Google Home (Cast) | Stream from applications | Depends on the network | Low |
Please note that when using mirroring methods (Screen Share, AirPlay), the load is placed on the smartphone, and it actively consumes battery. When using the protocol DLNA or built-in applications (YouTube, Netflix) with a "Stream" button, the phone acts only as a remote control, and the video is downloaded by the TV directly from the Internet, which saves battery.
Troubleshooting connection issues
Despite the simplicity of the technology, users sometimes encounter difficulties: the TV doesn't detect the phone, the image flickers, or there's no sound. Most often, the problem lies in energy saving settings or IP address conflicts on the local network.
If the devices can't find each other, try rebooting the router by completely unplugging it for 10-15 seconds. Also, check if the router has speed limits for individual devices or guest Wi-Fi mode enabled, which often isolates clients from each other for security reasons.
⚠️ Warning: Antivirus programs or firewalls on your smartphone may be blocking the local connection. Try temporarily disabling network protection or adding your TV to the list of trusted devices.
If you see a picture but no sound, check the audio output settings in the app you're streaming from. Sometimes the sound remains on your phone if "Audio output to external device" isn't enabled. Also, make sure your TV isn't set to silent or low volume.
Frequently Asked Questions (FAQ)
Is it possible to share a screen without the internet, only via Wi-Fi?
Yes, Miracast and AirPlay don't require internet access. Both devices need to be connected to the same router, which creates a local network. Some LG TVs support Wi-Fi Direct, which allows the phone to connect directly to the TV module without a router.
Why is the image on the TV not full screen?
This is due to the different aspect ratios of smartphone and TV screens. Smartphones often have elongated screens, while TVs use the 16:9 standard. In the TV settings (P:Ratio or Aspect Ratio button on the remote), you can try changing the display mode to "Original," "Just Scan," or "16:9" to remove black bars or stretch the image.
The video is lagging while streaming, what should I do?
Lag is most often caused by Wi-Fi congestion or a weak signal. Try switching to the 5 GHz band if your router supports dual-band operation. Also, close unnecessary apps on your phone and make sure no one is currently downloading large files over the same Wi-Fi network.
Does my old LG TV support AirPlay?
Native AirPlay 2 support is available on LG TVs running webOS 4.0 and later (2019 models and later). Older models can use third-party apps from the LG Content Store that emulate AirPlay reception, or use an Android set-top box.
