Modern televisions LG Smart TV Smartphones have become powerful multimedia centers, but often the content stored in a smartphone's memory is much larger than the pre-installed apps. The ability to instantly display photos, videos, or even gameplay on the screen AndroidLarge-screen devices are one of the most sought-after features among users. This eliminates the need to find cables and create complex wired connections, allowing you to enjoy content in the best possible quality, whether with friends or alone.
There are several proven methods for establishing a wireless connection, each with its own technical features and software requirements. Standard protocols Miracast And DLNA, as well as the company's proprietary developments LG, such as Smart Share, ensure stable data transfer. It's important to ensure both devices are on the same local network, as this is a fundamental requirement for successful discovery of each other without a router.
In this article, we'll cover all available synchronization methods in detail, from built-in system functions to installing specialized software. You'll learn how to set up lag-free image transmission, which video formats are supported natively, and how to resolve common connection issues if your TV stops detecting your phone.
Preparing equipment and network for broadcasting
The first and most critical step is to ensure a stable connection between your devices. The router must support the standards Wi-Fi Direct or work in the mode 5 GHz, which is especially important for transmitting heavy high-resolution video streams. If your router is older and only operates on the 2.4 GHz frequency, you may experience some lag when viewing 4K content, although this is usually sufficient for regular photos and Full HD videos.
Both devices - and a smartphone based on Android, and TV LG webOS — must be connected to the same Wi-Fi network. Users often encounter an issue where the phone is stuck on a 4G/5G mobile network while the TV is connected to the home Wi-Fi, making them invisible to each other on the local network. Check the connection status in the phone's system tray and in the TV's network settings menu.
⚠️ Important: Make sure that the AP Isolation feature is not enabled on your router, which prevents devices within the same network from communicating with each other.
It's also worth updating the software of both gadgets to the latest versions. In TVs LG This is done through the menu Settings → All settings → General → About TV → Check for updatesFor a smartphone, the path may differ depending on the manufacturer's shell, but is usually located in the section Software update in the system settings.
☑️ Check before connection
Using the built-in Screen Share (Miracast) feature
The most universal method, which does not require the installation of additional applications, is based on technology MiracastOn TV LG This function is often called Screen Share or simply "Screen Casting." It allows you to mirror your smartphone's image to your TV in real time, creating a direct Wi-Fi connection.
To get started, launch the application Screen Share on TV LGIt's usually found in the app list on the main panel or in the "More" folder. Once launched, the TV's name and "Pending Connection" status will appear on the screen. On some models, you may be prompted to allow the connection via a pop-up window.
On a smartphone Android The process may be called differently depending on the manufacturer: "Cast," "Smart View," "Wireless Monitor," or "Projection." Go to the notification shade (swipe down from the top) and find the corresponding button. If it's not visible, open the full quick settings menu.
- 📱 Click on the broadcast icon and wait for the device search.
- 📺 Select your TV LG from the list that appears.
- 🔗 Confirm the connection on the TV screen if prompted.
- 🖼️ Your smartphone screen will instantly be displayed on your TV.
Streaming via the LG TV Plus app
Official app LG TV Plus (formerly known as LG TV Remote) provides advanced control and content sharing functionality. It allows you to not only mirror your screen but also transfer media files from your phone's gallery using the protocol DLNA, which often provides better picture quality than simple mirroring.
Download and install the application from Google Play MarketOnce launched, the program will automatically scan the network and find a compatible TV. LGFor initial setup, you'll need to enter the code displayed on the TV screen or confirm pairing with the remote. This ensures the security of your connection.
In the app interface, go to the "Media" or "Gallery" section and select the desired video or photo. In the upper-right corner or from the three-dot menu, select "Cast" or the Cast icon. The video will begin playing on your TV, allowing you to use your phone for other tasks, as streaming occurs directly from your device to the TV, bypassing the smartphone's processor.
| Function | Miracast (Screen Share) | LG TV Plus (DLNA) | Google Cast |
|---|---|---|---|
| Transmission type | Screen mirroring | File streaming | Streaming from the app |
| Impact on battery | High (screen is lit) | Low (the screen can be turned off) | Average |
| Video quality | Depends on Wi-Fi signal | Maximum (original) | Depends on the service |
| Control | From the phone | From your phone or remote control | From the phone |
Using Google Cast technology (Chromecast built-in)
Many modern TV models LG with the operating system webOS have built-in support for the technology Google CastThis allows you to stream content directly from apps like YouTube, Netflix, VLC, or the Google Chrome browser without having to mirror your entire smartphone screen.
For this method to work, make sure Cast is enabled on your TV. It's usually enabled by default, but in rare cases, you'll need to enable it in the connection settings menu. Open a supported app on your phone, such as YouTube, and look for the familiar rectangle icon with Wi-Fi waves in the corner.
Click on the icon and select your TV LG from the list. The video will play on the big screen, and your phone will become a remote control. You can pause, rewind, and adjust the volume without interrupting playback. This is ideal for watching online movies.
⚠️ Note: App and TV interfaces may be updated. If you don't see the Cast button, check the "Cast" or "Devices" options in the app settings.
Third-party apps for video and photo transfer
When standard methods don't work or additional features are required, third-party solutions come to the rescue. Apps like Web Video Caster, BubbleUPnP or AllCast They do an excellent job of transmitting video files of any format that are not natively supported by the TV.
They work similarly: you install an app on your phone and, in some cases, a companion app on your TV (via the LG Content Store). However, most modern solutions use the DLNA protocol without installing software on the TV. You select a file in the app on your phone, and it streams it to the TV.
Such programs are especially useful for playing videos with subtitles or files in formats .mkv And .avi, which have a built-in player LG It might not "understand." The phone app acts as a transcoder, converting the stream on the fly into a format understandable to TV.
- 📥 Install the selected application (for example, Web Video Caster) from the Play Market.
- 📡 Open the app and select the "Broadcast" tab.
- 📺 Find your TV in the list of available devices.
- 🎬 Select a video file or link to an online video to start.
What should I do if the video is lagging?
If the video is choppy when streaming through third-party apps, try lowering the bitrate in the app settings or switching your router to a less-interference-prone channel. Disabling Bluetooth on your phone may also help, as it operates on the same 2.4 GHz frequency.
Troubleshooting connection and image quality issues
Even with proper setup, issues may still occur. If the TV doesn't detect your phone, try rebooting your router—this solves 90% of local network issues. Also, check if your router has a limit on the number of connected devices (MAC filtering).
If you experience artifacts, image tearing, or audio lag, the problem is likely a weak Wi-Fi signal. Move closer to the router or TV. If you're using the 2.4 GHz band, try switching to 5 GHz, which is less congested with neighboring networks and provides better throughput.
If there's sound but no image (black screen), check your DRM settings. Some content-protected videos (such as those from paid subscriptions) may block screen recording or streaming to external displays if they're not certified for this.
Frequently Asked Questions (FAQ)
Is it possible to display a screen on an LG TV without Wi-Fi?
Without a Wi-Fi router, full wireless streaming is impossible. However, if your router is broken, some phone models can create a hotspot, but the TV must be able to connect directly to it via Wi-Fi Direct, which is not available on all TV models.
Why is there a lot of lag when streaming a game?
Miracast technology has inherent latency due to the video stream encoding and decoding process. This can be critical for fast-paced games. It's recommended to use a cable connection or play games that don't require instant reaction time.
Does my old LG TV support Screen Share?
Screen Share (Miracast) is now available on LG Smart TVs (NetCast 4.0 and later, as well as all webOS platforms). If you have a very old model, you may need an external adapter like a Chromecast or Miracast dongle.
Is it possible to stream video with the phone screen closed?
When using the mirroring method (Miracast/Screen Share), the phone's screen must be lit. If you want to turn off the screen and only listen to music or watch videos, use media player apps with DLNA support (such as VLC or LG TV Plus), which stream the actual file, not the screen image.
