Modern technology makes it possible to turn any smartphone into a powerful multimedia control panel, but often the mobile device's screen is too small for comfortable viewing of movies or photos. LG with support Smart TV This problem can be easily solved by wirelessly transmitting images and sound. Synchronizing a gadget and TV via a local Wi-Fi network has become standard, eliminating the need for unnecessary wires and adapters.
There are several proven methods, each of which has its own characteristics depending on the version of the operating system. Android and your TV model. We'll cover the main data transfer protocols, such as Miracast, DLNA And AirPlay 2We'll also explore the nuances of third-party applications. Understanding the differences between these technologies will help you choose the best option for specific tasks, whether it's presenting a presentation or viewing 4K content.
Connection stability directly depends on the performance of your router and the correct network settings. In this article, we'll detail a step-by-step procedure that will allow you to enjoy content on a large screen without lag or artifacts. Even if you're not a tech expert, following our recommendations will help you quickly establish communication between your devices.
Wireless Data Transfer Technologies: Miracast vs. DLNA
Before you get started, it's important to understand the fundamental differences between the protocols used for streaming. Miracast (often called Screen Share or Smart View) creates a direct wireless connection between devices, effectively mirroring your smartphone's screen to your TV. This means everything that happens on your phone's display, including notifications and system sounds, will be visible and audible on the big screen.
Unlike mirroring, the technology DLNA It works differently: it allows you to stream only media files (videos, photos, music) from the device's memory or the cloud, without hijacking the operating system interface. In this case, the TV acts as a renderer, receiving the data stream from the smartphone controller. This allows you to use the phone for other tasks while watching a movie, which is impossible in Active Mode. Miracast.
The choice of protocol depends on your goals. If you need to share a photo album with friends or play a movie from your gallery, DLNA will provide higher image quality and reduce battery drain. For gaming, app sharing, or viewing content from browsers that don't support external streaming, screen mirroring is the way to go.
Preparing equipment and setting up a Wi-Fi network
The foundation for successful broadcasting is the correct operation of the local network. Both devices—and the smartphone— Android, and TV LG — must be connected to the same Wi-Fi access point. A common mistake users make is connecting their gadget to a 4G/5G mobile network and their TV to a home router, making them "invisible" to each other.
It is recommended to use a range 5 GHz, if your router and TV support this frequency. It provides the higher throughput needed to transmit high-definition video and is less susceptible to interference from neighboring networks and Bluetooth devices. Make sure that AP Isolation is not enabled on your router, which prevents devices within the network from communicating.
☑️ Checking connection readiness
It's also worth checking for firmware updates for your LG Smart TVManufacturers regularly release patches that improve the stability of the Wi-Fi module and compatibility with new versions. AndroidLack of up-to-date software may result in connection interruptions or failure to find the device during a search.
⚠️ Note: If your router broadcasts two networks with the same name (2.4 GHz and 5 GHz), make sure both devices are connected to exactly one of them, preferably 5 GHz for best performance.
Screen Share (Miracast) method for screen mirroring
The most universal way to mirror your phone's content to an LG TV is to use the built-in Screen Share feature. On LG TVs, this technology is implemented through an app, often called Screen Share or Display and control. Launch it on your TV so that it goes into connection standby mode.
On a smartphone with Android The procedure may vary slightly depending on the manufacturer's shell. Typically, you need to open the notification shade and find the button Broadcast, Smart View, Wireless monitor or Screen mirroringOnce the search is activated, your phone will find your LG TV in the list of available devices.
What to do if the phone doesn’t see the TV?
Make sure the Screen Share app is running on your TV and the search process is in progress. Try rebooting the Wi-Fi module on both devices. In rare cases, temporarily disabling your antivirus or firewall on your router may help.
After selecting your TV from the list, a connection confirmation prompt may appear on its screen. Accept it using the remote control. Your smartphone's screen will now be fully displayed on the TV. To exit, simply press the "Home" button on your phone or the "Stop" button in the casting menu.
It is important to take into account that when using Miracast The phone actively encodes the video stream in real time, which can lead to device heating and increased power consumption. Additionally, there may be a slight delay between the action on the phone screen and its display on the TV, which is normal for this technology.
Using DLNA to Play Your Media Library
To view video files stored in the smartphone memory or streaming from cloud storage, the technology DLNA This is the best option. Unlike screen mirroring, the TV decodes the video itself, offloading the phone's processor. To use this method, you need a media center app installed on your smartphone, such as VLC for Android, BubbleUPnP or built-in player Google Photos.
Let's look at the process using a popular player as an example. VLCAfter installing the app, open the "Network" or "Local Devices" tab. Your TV should appear in the list of available renderers. LGTap it, and the player will prompt you to select a file to play. Once the video starts, playback controls (pause, rewind, and volume) remain on your smartphone.
The advantage of DLNA is the ability to manage the playback queue and the phone's screen orientation. You can set your device aside or use it for messaging while watching a movie on TV. Picture quality is often higher, as the original video stream is transmitted without the intermediate compression typical of Miracast.
| Characteristic | Miracast (Screen Share) | DLNA |
|---|---|---|
| Transmission type | Mirroring the entire screen | Media files only |
| Using the phone | The screen is busy and cannot be used. | Can be used for other tasks |
| Image quality | Depends on the signal, compression is possible | Original file quality |
| Battery consumption | High | Average |
AirPlay 2 support on LG TVs
Owners of new LG TV models equipped with the operating system webOS versions 4.0 and above can take advantage of the technology AirPlay 2Although this protocol was developed by Apple, many modern Android smartphones have also learned to work with it or have built-in support through system functions. This ensures a stable connection and high transmission quality.
To activate the function on your LG TV, go to the settings menu and select General and find the section AirPlayMake sure the toggle is enabled. On an Android device, when attempting to stream content (for example, from YouTube or Google Photos), your TV may appear in the list of available devices with the AirPlay icon.
Using AirPlay 2 often results in a smoother picture and better audio synchronization compared to standard Miracast. Furthermore, this technology supports multi-room audio, allowing you to sync your TV's sound with other compatible devices in your home. However, it's worth keeping in mind that not all Android apps support direct AirPlay output without using system features.
⚠️ Note: The LG TV menu interface may vary depending on the webOS version. If you don't find the AirPlay setting, check the "Support" section or update your TV's software.
Broadcasting from browsers and streaming apps
The Cast function, built into many popular applications such as YouTube, Netflix, Google Chrome And VKThis method is the most convenient for watching online content, as the TV downloads video directly from the internet, using the smartphone only as a remote control. This frees up Wi-Fi traffic and the phone's processor.
To use this feature, open the desired application on your smartphone and find the icon Cast (a rectangle with waves in the corner). Click it and select your LG TV from the list. The video will start playing on the big screen, and the playback control interface will appear on your phone.
In the browser Google Chrome On Android, you can cast an open tab. To do this, tap the three-dot menu and select Broadcast...You can choose to cast a specific tab or the entire device screen. This is a great way to show the content of a website that doesn't have a native Smart TV app.
Solution and troubleshooting
Despite the simplicity of the technology, users may encounter connection issues. One of the most common causes is IP address desynchronization or a temporary router malfunction. If devices stop seeing each other, try rebooting the router by completely unplugging it for 10-15 seconds. This will clear the network cache and renew DHCP leases.
Another common issue is antivirus software or router firewall settings, which can block the ports used for DLNA and Miracast. Try temporarily disabling protection or adding devices to the trusted list. Also, make sure your TV is configured to accept connection requests (usually by displaying an "Accept" pop-up window).
If the video streams but constantly buffers or cuts out, the problem may be a weak Wi-Fi signal. Move the router closer to the TV or use a Wi-Fi extender. For desktop LG TVs, it may be advisable to use a wired LAN connection for stability, reserving Wi-Fi for mobile devices only.
⚠️ Please note: Software specifications and interface are subject to change by manufacturers. Up-to-date instructions are always available in the "Support" section of the official LG website or in the "Help" menu on your TV.
