Modern smartphones They have powerful multimedia capabilities, but even the highest-quality display won't replace a large TV screen for watching movies or playing games. Owners of these devices LG People often wonder how to quickly and easily stream images without unnecessary wires. Fortunately, built-in protocols Wi-Fi Direct and Smart TV technologies allow you to do this in a matter of seconds.
In this article, we'll cover all available connection methods in detail, from built-in system features to third-party apps. You'll learn how to avoid lag, set up high resolution, and what to do if devices can't see each other. The key condition for all methods is that the gadget and TV are located in the same local Wi-Fi router network., which ensures stable data transmission.
There are several main ways to accomplish this task, and the choice depends on the operating system of your phone. For owners Android native "Broadcast" or Smart View functions are available, while users iPhone can use AirPlay 2 technology built into new LG TV models. Let's look at each option step by step.
Equipment preparation and basic requirements
Before you begin setup, you need to make sure your equipment meets the minimum requirements. First and foremost, your TV must support Smart TV functionality, which is required for most LG models released after 2012 with the platform. WebOSOlder "dumb" TVs will require an external set-top box.
Proper network configuration is critical. Devices must be connected to the same network, not just have Wi-Fi enabled. Users often make the mistake of connecting their phone to a 4G/5G mobile network and their TV to their home router—in this case, the connection will fail.
- 📺 LG Smart TV (WebOS 3.0 or higher preferred).
- 📱 Smartphone with a current operating system (Android 8.0+ or iOS 12+).
- 📡 A stable router operating in the 2.4 GHz or 5 GHz range.
⚠️ Important: If your router broadcasts two networks with the same name (2.4 GHz and 5 GHz), make sure both devices can see each other. On some corporate networks or hotel Wi-Fi, broadcasting may be blocked by security settings.
It's also worth checking for software updates on both devices. Manufacturers regularly release patches that improve protocol stability. Miracast And DLNAGo to your TV settings and check for system updates to rule out software conflicts.
To check your network's readiness, you can use the built-in connection test on your TV. If the network is working correctly, we can move on to choosing a connection method, which depends on your smartphone brand.
Streaming from Android smartphones via Miracast
The most common method for devices based on Android - use of technology Miracast, which is built into the system. Depending on the smartphone manufacturer, this feature may be called differently: Smart View for Samsung, "Cast" for stock Android, "Wireless Monitor" for Xiaomi, or "Screen Mirroring" for Huawei.
The device search process is usually automatic. You don't need to enter IP addresses or complex passwords; simply select the TV from the list of available devices. The image from your phone's screen is mirrored to the TV in real time, allowing you to display presentations, photo galleries, or game interfaces.
☑️ Check before connection
It's worth noting that when broadcasting via Miracast, the phone's screen does not turn off, and battery consumption increases significantly. Permission The transmitted image quality is adapted to the capabilities of the TV, but may be limited by the bandwidth of your Wi-Fi channel.
- 🔍 Open the notification shade on your smartphone.
- 📺 Find the "Broadcast", Smart View, or Project icon.
- 📲 Wait until your LG TV's name appears in the list.
- ✅ Click on the name and confirm the connection on the TV.
If you don't find the option you need in the standard menu, try searching for it in the "Connections" or "Display" section of the general system settings. Sometimes the function is hidden in the "Other connection settings" submenu.
Using AirPlay 2 for iPhone Owners
Users of technology Apple are in an advantageous position, as modern LG TVs support native technology AirPlay 2This allows you to stream content directly from apps or mirror the entire screen without installing additional software on your TV.
To get started, make sure AirPlay support is enabled on your TV. This is usually done automatically, but some models require manual activation in the settings menu. This protocol often offers higher image quality than Miracast, with lower latency.
To start casting, open Control Center on your iPhone (swipe down from the upper-right corner or swipe up on older models) and tap the "Screen Mirroring" button. The system will automatically find a compatible LG TV on the network.
⚠️ Important: When connecting for the first time, a 4-digit code may appear on the TV screen. You must enter this code on your iPhone to verify that the device is trusted. Do not share this code with anyone.
The advantage of AirPlay 2 is the ability to control playback directly from your phone without interrupting the stream. You can minimize an app, reply to a message, or launch another game, and the image on your TV will continue playing, if the specific app supports it.
The official LG TV Plus app
For more in-depth control of the TV and streaming of multimedia files, manufacturers recommend using a proprietary application LG TV Plus (formerly known as LG Remote). It is available for download for free on Google Play and the App Store.
The app functions as a remote control and media center. You can not only mirror your screen, but also transfer specific photos and videos from your phone's gallery to the big screen, control the Magic Remote cursor, and even type using your smartphone's keyboard.
The pairing process is simple: launch the app on your phone, and it will begin searching for TVs on the network. After selecting your LG model, a connection permission request will appear on the TV screen. Once confirmed, your phone and TV will be connected.
What should I do if the app doesn't detect the TV?
If the automatic search doesn't yield any results, try manually adding the device by IP address. You can find the TV's address in the network settings of the TV itself (Settings -> Network -> Wi-Fi connection -> Advanced settings). Enter the numbers exactly, without extra spaces.
A key feature of the app is the ability to stream browser content. You can open a webpage on your phone and display it on your TV, which is convenient for viewing websites that don't have a dedicated Smart TV app.
Third-party streaming apps
When standard methods don't work or the functionality isn't sufficient, third-party solutions come to the rescue. The leader in this area is the app TV Cast (Web Video Caster), which allows you to stream video from your browser, avoiding file format issues.
Another popular solution is Miracast & TV CastThese apps often offer more flexible bitrate and resolution settings, which can improve image quality on weak Wi-Fi connections. However, be prepared for ads in the free versions.
Using third-party software is especially useful if you want to stream video files stored on your phone's memory in formats that your TV's native player can't read (for example, specific codecs like MKV or AVI). The app on your phone will handle the decoding.
| Application | Platform | Main function | Presence of advertising |
|---|---|---|---|
| LG TV Plus | Android / iOS | Remote + Photo/Video | No |
| Web Video Caster | Android / iOS | Broadcast from a browser | Yes (Free) |
| LocalCast | Android | File streaming | Eat |
| Replica | iOS | Full screen mirroring | Eat |
When choosing a third-party app, pay attention to the permissions it requests. To function correctly, the program requires access to the local network and media files. Without these permissions, streaming is impossible.
Stream via Chromecast built-in
Many modern LG TVs come with built-in support Google ChromecastThis allows you to stream content directly from apps like YouTube, Netflix, TikTok, or Spotify without mirroring your entire phone screen.
Unlike mirroring (Miracast), the phone only acts as a remote control. The TV downloads video directly from the internet, saving battery power and freeing it up for other tasks.
To use this feature, find the rectangle icon with Wi-Fi waves in the corner in an app (such as YouTube). Tap it and select your LG TV. The video will start playing on the big screen, and you can use your phone to type or access other apps.
Picture quality is typically superior when using Chromecast, as the TV decodes the stream itself using its powerful processors. Latency is virtually eliminated, making this method ideal for watching movies.
Troubleshooting and troubleshooting
Despite the simplicity of the technology, users may encounter problems: the TV isn't visible in the list, the image is choppy, or there's no sound. Most often, this is due to an unstable Wi-Fi signal or a software glitch.
If the devices can't find each other, try rebooting the router. This simple but effective action clears the network cache and redistributes IP addresses. Also, check if the "Guest Network" feature is enabled on the router—devices on a guest network are often isolated from each other.
- 🔄 Restart the TV (unplug it completely for 10 seconds).
- 📶 Check that your phone has not switched to a 4G mobile network.
- 🛡️ Disable the VPN on your smartphone if it is activated.
- 📲 Uninstall the LG TV Plus app and reinstall it.
⚠️ Note: Menu interfaces and item names may vary slightly depending on the webOS version and TV year. If you don't find an exact match, look for similar sections in the network or connection settings.
If the image is streaming but with delays, try lowering the resolution in the streaming settings on your phone or moving closer to the router. This method may not be suitable for gaming due to input lag; an HDMI cable is better.
Comparison of connection methods
Each of the methods discussed has its advantages and disadvantages. The choice depends on your goals: whether you need to duplicate the entire screen for a presentation or simply run a movie. Understanding the differences will help you choose the best option.
Built-in protocols (Chromecast, AirPlay) are best for watching videos, as they provide better quality and don't drain battery power. For sharing app or game interfaces, Miracast is indispensable, despite its resource consumption.
Keep in mind that the quality of your Wi-Fi signal directly impacts the picture. If your router is far away, even the best streaming method will be choppy. In such cases, consider using a Wi-Fi extender or switching to a wired connection.
Why doesn't my LG TV detect my phone?
The most common issue is that the devices are connected to different networks (for example, one to 2.4 GHz, the other to 5 GHz, and the router is isolating them). It's also possible that the Screen Share app isn't running on the TV, or that Stealth mode is enabled. Check the Wi-Fi privacy settings on your phone.
Is it possible to display the screen via USB cable?
Direct USB connection for image output (like HDMI) is generally not supported on LG TVs. USB ports are used for playing files from flash drives. For a wired connection, use a USB-C to HDMI adapter or MHL if your phone supports video output.
The video is lagging while streaming, what should I do?
Reduce the video quality in the app, close background apps on your phone, and move closer to the router. If you're using Miracast, try lowering your phone's screen resolution before connecting.
Does the operator charge for broadcasting?
No, Wi-Fi technology itself is free. However, if you stream online videos (YouTube, Netflix), your data plan will be used. If you're not connected to your home Wi-Fi but are sharing data from your phone, your data plan will be charged.
