Modern multimedia capabilities make it easy to stream content from a mobile device to a large screen, but users often face difficulties during initial setup. If you are the owner Apple iPhone and TV LG Smart TV, you're in luck: the ecosystems of these brands work seamlessly together when approached correctly. The core principle is the use of a single wireless network that connects devices into a local cluster for data exchange.
There are several video transmission protocols, each with its own characteristics and applications. The most popular and stable is AirPlay 2, built directly into the iOS operating system, ensuring high responsiveness. However, older TV models or specific tasks may require alternative methods, such as DLNA or a proprietary application LG TV Plus.
In this article, we'll take a detailed look at all available synchronization methods, focusing on the nuances of setting up your router and software components. You'll learn how to avoid image lag, why your TV might not recognize your phone, and which file formats are supported out of the box. Proper network configuration is the key to comfortable viewing of movies and presentations without the hassle of cables.
Preparatory stage: checking the network and compatibility
Before you begin pairing devices, you need to ensure that your infrastructure is ready to handle heavy video streaming. It is critical that iPhone, And LG Smart TV Connected to the same Wi-Fi access point. If you have a dual-band router, make sure both devices are on the same frequency band (e.g., 5 GHz), although modern routers usually correctly route traffic between 2.4 and 5 GHz within the same local network.
Please check your TV model as it does not support native AirPlay 2 appeared only in models released after 2018 and equipped with an operating system webOS 4.0 and above. For older models running on the platform NetCast or earlier versions webOS, you will need to install additional software or use third-party intermediary applications.
⚠️ Attention: Some corporate or public Wi-Fi networks (in hotels and offices) have client isolation (AP Isolation), which prevents devices from seeing each other. Under these conditions, wireless connection is impossible, even if the password is entered correctly.
It's also worth updating the software on both devices to the latest versions. On the TV, this is done through the settings menu, and on the smartphone, through Settings → General → Software UpdateOutdated Wi-Fi module drivers can cause unstable connections or a complete inability to detect devices on the network.
☑️ Checking connection readiness
Method 1: Stream via AirPlay 2 (Native Support)
This is the most preferred method for owners of modern TVs. LG, as it provides minimal latency and high image quality. Technology AirPlay 2 It's built right into the iOS interface, so there's no need to install any additional apps on your iPhone. Just make sure the feature is enabled in your TV's settings.
To enable the function on your LG TV, go to the settings menu and select the section Support, then find the item Apple AirPlay and HomeKit and move the switch to the position OnHere you can also set up a code requirement for connection, which will increase the security of your network and prevent unauthorized access to your screen.
To start casting, open Control Center on your iPhone (swipe down from the upper-right corner or swipe up on older models). Tap the "Screen Mirroring" icon (two rectangles), select your TV from the list, and, if prompted, enter the code displayed on the TV screen. Your smartphone's image will instantly appear on the big screen.
- 📱 Full integration with the iOS interface without any extra steps.
- 🎬 Support for high-quality audio transmission and multi-channel audio.
- 🔒 Data stream encryption to protect confidential information.
- ⏸️ Ability to control playback directly from the iPhone lock screen.
If the image is streaming but there's no sound, check the audio output settings in Control Center. Sometimes the system defaults to outputting audio through the phone speaker even when the video is playing on the TV. Also, make sure that "Video Only" mode isn't enabled on your TV, if this option is available in your firmware version.
Method 2: Using the LG TV Plus app
If your TV is an older model or you prefer to use the manufacturer's proprietary tools, the app LG TV Plus will be a great solution. It is available in App Store It's free and allows you to not only stream media files but also use your smartphone as a remote control with advanced functionality.
After installing the app, launch it and follow the on-screen instructions. The program will automatically scan your local network and find a compatible TV. When connecting for the first time, you may see a permissions request on the TV screen, which you must confirm using the remote. This is standard procedure. mating devices.
In the app, go to the "Media" or "Gallery" section, select the desired file (photo, video, or music), and tap the cast icon. Unlike AirPlay, you cast a specific file, not the entire smartphone screen, which saves battery life and allows you to use your phone for other tasks while watching.
| Function | AirPlay 2 | LG TV Plus | DLNA (Standard) |
|---|---|---|---|
| Broadcast type | Screen mirroring | Selective files | Selective files |
| Delay | Minimum | Absent | Absent |
| TV control | No | Complete | No |
| Requirements | webOS 4.0+ | Any Smart TV | Any Smart TV |
The app also lets you create playlists and manage playback queues, which is especially convenient for hosting parties or presentations. You can add files from different iPhone folders and even cloud storage services linked to the app, creating a unified content feed for on-screen display.
Method 3: Streaming via DLNA and third-party apps
In cases where native methods don't work or you need to play specific video formats that aren't supported by the standard LG player, technologies come to the rescue. DLNA and third-party transmitter applications. These programs, such as iMediaShare, Cast to TV or BubbleUPnP, act as an intermediary, converting the stream on the fly or simply transmitting data in a format understandable to the TV.
The principle of operation is simple: you install the application on your iPhone, it finds the TV on the network (often identifying it as DLNA Renderer), and you select the file to play. The main advantage of such programs is their support for a huge number of codecs and containers, including those that don't work via standard AirPlay.
⚠️ Attention: Free versions of third-party apps often contain ads or have video length limitations. Regular use may require purchasing a premium version.
Some apps allow you to stream not only files from your storage but also content from your Safari browser. To do this, copy the video link to the clipboard or use the "Share" feature in your browser and select the icon of the installed DLNA app. This is a great way to watch online videos from sites that don't have built-in AirPlay support.
It's important to note that using third-party software places a strain on the smartphone's processor, as it's responsible for decoding or transcoding the stream. Therefore, the battery may drain faster than when using native software. AirPlay, where some of the tasks are taken over by the TV chip.
Why does the video stutter when streaming via DLNA?
Most often, the problem lies in the slow write speed to the router's flash memory or a weak Wi-Fi signal. DLNA requires a stable connection, as buffering occurs in real time. Try lowering the source file quality or moving the router closer to the viewing area.
Screen Mirroring vs. Video Streaming
Users often confuse two concepts: screen mirroring and media file streaming. Mirroring It completely replicates what you see on your iPhone display, including notifications, the home screen, and app interfaces. This is useful for showing presentations, playing games, or navigating maps, but image quality may be lower due to video compression.
Video casting sends only a link to a file or stream to the TV, and the TV downloads and decodes the content itself. This ensures maximum quality (up to 4K HDR), and the phone can be used for calls or other tasks without interrupting playback. The choice of method depends on your ultimate goal.
If you want to show the interface of an application that does not support external broadcasting (for example, a banking application or games), only the mirroring mode will help you through AirPlayTo do this, you need to select "Screen Mirroring" in the Control Center, not the broadcast icon within a specific video player.
- 🎮 For games, use only mirroring.
- 🎥 For movies, select the built-in "Stream" button in the player for better quality.
- 🔋 Mirroring uses significantly more battery power.
- 📱 Notifications on your iPhone will be visible on your TV when in mirroring mode.
It's worth keeping in mind that some content-protected apps (such as Netflix or Disney+) may block screen mirroring due to copy protection policies. HDCPIn such cases, the TV screen will be black, although sound may still be transmitted. This is not an error, but normal behavior of the copyright protection system.
Solution: The TV doesn't detect the iPhone or the connection is interrupted
One of the most common problems is when devices are on the same network but cannot see each other. First, try rebooting your router, as temporary errors in the routing table can prevent protocols from discovering devices. mDNS And SSDPRestarting the Wi-Fi module on the TV itself via the network settings menu also helps.
If the problem persists, check your router's firewall settings. Some router models have an "IoT Protection" feature that isolates smart devices from each other by default. Find the local network section in your router settings and enable Local Network Access.
Another common cause is using a guest Wi-Fi network. Guest networks are, by definition, isolated from the main network, so if your phone is on the guest Wi-Fi and your TV is on the main network (or vice versa), they will never find each other. Make sure both devices are connected to the main SSID.
⚠️ Attention: Antivirus software or VPNs enabled on your iPhone may hide the device from your local network. To establish a connection, temporarily disable the VPN and firewall on your smartphone.
In rare cases, resetting the network settings on the TV helps. Go to Settings → Network → Wi-Fi connection, select your network, click "Edit" or "Delete," and then reconnect by entering the password. This will clear the network settings cache and force the TV to re-register with the network.
Frequently Asked Questions (FAQ)
Is it possible to connect an iPhone to an LG TV without Wi-Fi?
Yes, this is possible using a wired Lightning to HDMI adapter (or USB-C to HDMI for newer models). However, this method requires purchasing additional equipment and prevents full use of the smartphone while watching, as it will be busy transmitting the signal.
Why is there no sound when connecting via AirPlay?
Check that your Bluetooth headphones aren't connected to your iPhone. Also, make sure the audio output isn't limited in your TV's AirPlay settings. Sometimes switching the audio source in the iPhone's Control Center (the AirPlay icon in the music controls) can help.
Does my old LG TV support AirPlay?
Native AirPlay 2 support is available in 2018 and newer models (B8, C8, E8 series and above, as well as all 2019+ models). Older models (2014-2017) will require third-party repeater apps or a set-top box (Apple TV, Chromecast).
How to improve picture quality during broadcasting?
Use the 5 GHz band for your Wi-Fi connection, as it's less congested and provides higher throughput. Also, try to position your router within direct line of sight of your TV or use a Wi-Fi repeater to boost the signal in the viewing area.
Is it safe to stream personal photos to TV?
Yes, if you're on your home network. However, if you're in a remote location or using a complex router, we recommend setting a passcode in the AirPlay settings on your TV to prevent unauthorized access to your session.
