Modern televisions LG Smart TV They've ceased to be mere devices for receiving broadcast signals and have become powerful multimedia centers. The ability to display images from a smartphone on a large screen opens access to thousands of apps, games, and personal photo archives, which are much more enjoyable to view on a 55- or 65-inch screen. Connecting via local Wi-Fi network is the most convenient method, as it eliminates the need to look for adapters or run wires across the entire room.
The process of synchronizing devices is based on DLNA technology or proprietary solutions of the manufacturer, such as LG TV PlusYou don't need to be a networking expert to set up data transfer, but it's important to understand the basic principles of wireless protocols. Both devices must be on the same router subnet, even if one is connected by cable and the other by air., otherwise detection may not be possible.
In this article, we will examine in detail all available broadcast methods, from the built-in functions of the system WebOS Before using third-party software, we'll cover the nuances for owners. Android smartphones and devices based on iOSWe'll also cover connection stability and signal quality. A willingness to experiment and a working router are all you need to get started.
Preparing equipment and checking network settings
Before moving on to software settings, you need to ensure that your hardware is physically ready. The first and most important step is to check that your router Provides a stable signal. If your phone's internet connection is slow or intermittent, high-definition video streaming will be accompanied by buffering and image artifacts.
Make sure that on your TV LG The latest Wi-Fi module is installed. In older models, released before the widespread adoption of standards 802.11n, data transfer speed may be limited, which will impact image quality. Modern models support dual-band networks, which significantly increases channel throughput.
It is critical that both devices - the smartphone and the TV - are connected to the same networkUsers often encounter a problem where their phone is connected to a 4G/5G mobile network while their TV is connected to their home Wi-Fi. In this mode, they "cannot see" each other, as they are in different virtual spaces.
⚠️ Attention: If your router supports the "Guest Network" feature, do not connect streaming devices to it. This feature isolates clients from each other for security purposes, and the TV simply won't be able to receive the phone's signal.
To check the signal quality, you can use the built-in diagnostic tools. On TVs LG This is done through the network settings menu. You need to go to the section Settings → All settings → Network → Wi-Fi Connection and check the signal strength. If it's below 50%, we recommend moving the router closer or using a Wi-Fi repeater.
Using the built-in Screen Share feature on your LG TV
In the operating system WebOS, which is installed on most modern TVs LG, the image receiving function is already built in. It is based on the standard Miracast, which allows you to broadcast your smartphone's screen without using an additional router, creating a direct Wi-Fi connection between devices.
To activate standby mode on your TV, take the remote control Magic Remote and press the "Home" or "Input" button. Find the app in the list of signal sources or in the start menu. Screen Share (In some firmware versions, it may be called "Screen Casting" or "Connect to Mobile Device"). Launching this app makes the TV visible to external devices.
After launching, a message will appear on the TV screen indicating that the device is ready to connect, and possibly a confirmation request. At this point, the TV begins actively scanning the airwaves for smartphone requests. The interface may prompt you to select the connection type: computer or mobile device—select the latter.
☑️ Check before launching Screen Share
It is worth noting that when using technology Miracast The image is transmitted in real time. This means that any notifications coming to your phone (messages, calls) will be visible to everyone watching the TV screen. This may be undesirable when watching movies in a group.
Cast from Android: Smart View and Google Cast
For owners of smartphones based on Android The connection process is as simple as possible thanks to the integration of Google services. If you have a device from Samsung, the function is called Smart View, at Xiaomi - "Broadcast" or "Wireless Monitor", and on "clean" Android — "Cast Screen." The procedure is the same for everyone; only the menu item names differ.
Pull down the notification shade on your phone and find the casting icon. Once you tap it, your phone will begin searching for available devices. Your device should appear in the list. LG TVIf the TV is not displayed, make sure you have launched the app first. Screen Share on the TV itself, as described in the previous section.
After selecting a TV from the list, a connection permission prompt may appear on the TV screen. Use the remote control to press "Confirm" or "Accept." From this point on, the phone's image is fully mirrored on the big screen. Latency in this mode is minimal, but depends on the phone's processor speed and the quality of the Wi-Fi connection.
The technology is worth mentioning separately. Google Chromecast built-in, which is built into many new models LGIt works differently than Miracast: instead of mirroring your entire screen, you stream content from a specific app (like YouTube or Netflix). This frees up your phone: you can minimize the app, answer a call, or even turn off your smartphone's screen, and the video will continue playing on your TV.

Solving connection and signal stability issues
Despite the technology's refinement, users may encounter difficulties. The most common issue is that the TV isn't visible in the list of available devices. In 90% of cases, this can be resolved by simply rebooting the router. Electronics tend to accumulate errors in their cache, and rebooting network equipment often works wonders.
If the issue persists, check your router's firewall or antivirus settings. Some security features may block local connections between devices (DLNA/Miracast). Try temporarily disabling "Wi-Fi Protection" or "Client Isolation" in your router settings.
Another cause of problems could be outdated software. Go to your TV settings. Settings → All settings → Support → Software update and check for new versions. Manufacturers regularly release patches that fix wireless module bugs.
⚠️ Attention: The menu interface and item names may differ slightly depending on the version of the operating system installed. WebOS (3.0, 4.0, 5.0, 6.0 and later). If you don't find the specified item, look for a similar one in related settings sections.
It's also worth paying attention to channel congestion. If your apartment has many neighboring Wi-Fi networks, interference may occur. Switching your router to a less congested channel or using the 5 GHz band instead of 2.4 GHz can dramatically improve connection stability.
