Apple smartphone owners often face the desire to display images from a small screen on a large home theater display. Modern Smart TV LG devices offer extensive integration with the iOS ecosystem. This allows you to not only watch videos or photos, but also show presentations or play games on the big screen without the hassle of wires. The synchronization process has become significantly easier with the advent of this technology. AirPlay 2, which is now built into many TV models.
There are several ways to accomplish this task, and the choice of a specific method depends on the year of manufacture of your TV and the version of the operating system. tvOSSome models support native wireless data transfer, while older devices will require additional software solutions. Understanding how it works local network This will help you avoid delays and audio desynchronization. In this article, we'll cover all current connection methods in detail, omitting complex technical terms where possible.
Before starting any manipulations, you must ensure that both devices—the smartphone and the TV—are working correctly. It is important that the software on both devices is updated to the latest available version. This ensures that the necessary security protocols and connection stability. We'll cover both standard Apple tools and specialized software available in the app store.
Preparation of equipment and network infrastructure
The foundation of successful wireless broadcasting is a stable local network. Both devices must be on the same Wi-Fi networksIf your router supports dual-band mode (2.4 GHz and 5 GHz), it is recommended to use the 5 GHz frequency for transmitting high-definition video streams, as it provides greater throughput. However, it is important to remember that this frequency range is shorter, so router and the TV should be located relatively close to each other.
Check your TV's energy saving settings. Some LG models may go into sleep mode or turn off Wi-Fi to save power, which will interrupt your connection. Go to the settings menu and find the section responsible for eco mode or automatic shutdown. Make sure the fast boot feature (Quick Start+) is activated, this will allow the TV to respond faster to external connection requests.
⚠️ Note: If you're using a guest Wi-Fi network or a corporate network with client isolation enabled, the devices won't be able to see each other. To stream, the smartphone and TV must be on the same network segment with data exchange enabled.
It's also worth paying attention to your network's congestion. If you're downloading large files or streaming 4K content on other devices, your TV's picture quality may deteriorate. Buffering Stuttering and jerky images are a direct consequence of bandwidth constraints. For the best experience, it's recommended to pause heavy downloads while viewing.
Using AirPlay 2 technology on LG TVs
Since 2019, LG has implemented support for the standard AirPlay 2 to your webOS-based Smart TVs. This is the preferred method, as it ensures minimal latency and high picture quality without installing additional software on the TV. This technology allows you to stream videos, music, photos, and even the entire device screen. This feature requires no cable, only a stable connection. wireless channel.
To activate the feature, take your TV remote and press the settings button (gear). In the menu that appears, select Connection or go to Settings → Support → AirPlayIn some firmware versions the path may differ, for example: Settings → General → AirPlay & Home Sharing. Make sure the switch is in the on position. OnIf the AirPlay option is not available in the menu, your TV model may not support this feature or may require a software update.
After activation, a code may appear on the TV screen. Take your iPhone, open Control center (swipe down from the top right corner or from the bottom up, depending on the model). Tap the icon Screen mirroring (two rectangles). Select your LG TV from the list of available devices. If prompted, enter the code displayed on the TV screen into the field on your smartphone.
- 📱 Open Control Center on your iPhone and tap the Cast icon.
- 📺 Select your LG TV from the list of available AirPlay devices.
- 🔢 Enter the four-digit code if it is displayed on the TV screen.
- 🎬 Content from your iPhone will appear on the big screen, and the phone can be used as a remote control.
It's important to note that AirPlay 2 supports multi-user mode. This means that multiple Apple devices can be connected to the TV simultaneously, although only one device is typically actively broadcasting. This technology also allows you to use your iPhone as a remote control for playback or volume adjustments, which is very convenient in the dark to avoid the bright light from your smartphone's screen.
What should I do if AirPlay isn't working on a supported model?
If your TV officially supports AirPlay 2 but the feature won't activate, try resetting your network settings. Go to Settings → Support → Self-Diagnostics → Smart Reset. Also, check if your antivirus or router firewall is blocking the ports required for the Bonjour protocol (5353).
Streaming via the LG TV Plus app
For models released before the introduction of AirPlay, or for users who require advanced file system management, LG has developed an official app LG TV PlusThis method allows you to not only mirror your screen, but also control your TV from your phone and stream media files directly. The app is available for free in App Store and requires LG account registration or login via social networks.
After installing the app, launch it on your iPhone. The app will automatically search for available TVs on your local network. When your LG TV appears in the list, tap its name. A connection permission prompt may appear on the TV screen. Confirm it using the remote. You can now go to the Settings tab. Media Link or Broadcastto select a photo or video from your phone gallery.
A unique feature of this method is the ability to use your phone as a touchscreen control panel. You can type text to search for videos on YouTube or Netflix directly from your iPhone keyboard, and the text will appear in the search bar on your TV. This eliminates the need to use the virtual keyboard on the remote, which is especially useful for complex queries or passwords. Wi-Fi networks.
☑️ Pre-launch check for LG TV Plus
It's worth keeping in mind that the image quality of third-party apps may be inferior to native AirPlay. Latency may be more noticeable, especially when watching fast-paced videos. Furthermore, the app may experience instability when switching between different types of content. This method is ideal for viewing static photos or slideshows, but for games or movies, it's better to consider other options.
Alternative apps for screen mirroring
If the built-in tools don't meet your needs or your TV model is too old, third-party apps can help. The App Store offers a wide range of programs, such as Cast to LG, TV Assist or ReplicaThese apps use DLNA protocols or proprietary video compression algorithms to transmit images. They often have more flexible settings, allowing you to adjust image quality based on your internet speed.
The operating principle of these programs is similar: you install the app on your iPhone, and a companion app from the LG Content Store is downloaded to your TV (if required). However, many modern solutions use the technology Cast, where the phone acts as a server and the TV simply receives the stream. This reduces the load on the smartphone's processor, but requires a very stable connection.
Some apps offer paid subscriptions to remove restrictions such as ads or session time limits. Before installing, carefully read reviews and iOS version requirements. Free versions often have limited functionality, suitable only for displaying photos, but not for full screen mirroring with sound.
| Application | Connection type | Sound support | Delay |
|---|---|---|---|
| AirPlay (Native) | Built-in | Yes (Synchronously) | Minimum |
| LG TV Plus | Official | Partially | Average |
| Cast to LG | Third party | Yes | High |
| TV Assist | Third party | No (video only) | Average |
⚠️ Warning: When using free third-party apps, your data may be transmitted through the developer's servers. Do not use such programs to share sensitive information, passwords, or personal photos unless you are confident in the security policy of the specific service.
Troubleshooting connection and buffering issues
Even with ideal settings, glitches can occur. The most common issue is that the TV isn't in the list of available devices. In this case, first check if it's turned on. DLNA in the TV settings. This protocol is responsible for discovering multimedia devices on the network. Also, try rebooting your router, as the ARP address table sometimes becomes full, causing devices to stop "seeing" each other.
If the image is streaming but is constantly interrupted or you see a message about low network speed, try lowering the resolution of the streamed video. You can often select the quality in your iPhone's settings or the streaming app. 720p instead of 1080p or 4KThis will significantly reduce the load on the communication channel. Also, make sure there are no thick concrete walls or metal structures between the router and the devices that could block the signal.
Sound issues where video plays but no audio are often resolved by switching the audio output. In the iPhone's Control Center (under Music or AirPlay), make sure the TV speaker is selected, not the phone speaker. Sometimes, simply turning Bluetooth on and off on your smartphone helps, as some systems use Bluetooth for the initial handshake before transmitting data over Wi-Fi.
- 🔄 Restart your router, TV, and smartphone one by one.
- 📡 Make sure both devices are connected to the same Wi-Fi frequency (2.4 or 5 GHz).
- 🔊 Check your audio output settings in your iPhone's Control Center.
- 📉 Reduce video quality in the app settings if your network is congested.
In rare cases, outdated router firmware can cause problems. Manufacturers regularly release updates that fix issues with new encryption standards and multicast protocols. If all else fails, try temporarily disabling WPA3 security on your router and switching to WPA2, as older LG devices may not work correctly with the latest security standards.
Comparison of wired and wireless methods
Despite the convenience of WiFi, a wired connection via an adapter Lightning to HDMI (or USB-C to HDMI for newer models) remains the benchmark for stability. The cable ensures uncompressed and latency-free signal transmission, which is critical for gamers or when displaying presentations with small text. Wireless always carries the risk of interference, especially in apartment buildings where the airwaves are clogged with signals from neighboring routers.
However, a cable limits mobility. You're tied to the length of the cord and can't move away from the TV to answer a call or get a cup of tea without interrupting the stream. A WiFi connection gives you the freedom to move around the room within the router's range. Furthermore, connecting a cable often requires purchasing an expensive, original Apple adapter, while software-based methods are free.
In terms of power consumption, wireless streaming significantly drains the iPhone's battery. Video encoding and constant high-load operation of the WiFi module can drain the battery in 2-3 hours. With a wired connection, the phone, on the other hand, charges from the TV or adapter. The choice of method depends on your priorities: maximum quality and reliability (wired) or convenience and wireless freedom (WiFi).
Is it possible to connect an iPhone to an LG TV without the Internet?
Yes, you can. AirPlay and most streaming apps don't require internet access. It's enough for the router to create a local area network (Local Area Network), even if the ISP cable is disconnected. Devices exchange data directly through the router. However, watching online videos from YouTube or Netflix will, of course, require internet access.
Why doesn't the TV see the iPhone in the AirPlay list?
Most often, the issue lies in privacy settings. Your TV's AirPlay menu may be set to "Current programs only" or "No code required," which can sometimes cause conflicts. Try selecting "Always allow" in the AirPlay settings on your TV or resetting the list of trusted devices. Also, make sure Bluetooth is enabled on both devices.
Does connecting a phone affect picture quality?
When using AirPlay 2 and modern codecs, the impact is minimal. However, if you use older DLNA protocols or cheap third-party apps, the image may be compressed, resulting in artifacts (blocky) during fast-moving scenes. Native AirPlay tries to maintain a balance between quality and bitrate automatically.
Will the sound come through the TV when mirroring the screen?
By default, audio should switch to the TV. If this doesn't happen, check if Bluetooth headphones are connected to your iPhone. Some apps (such as Zoom or Skype) require you to manually select the audio output device after you start broadcasting, as they may use your phone's speaker.
Do all LG Smart TV models support AirPlay?
No, AirPlay 2 support is available for models released in 2019 and later, as well as some updated 2018 models running webOS 4.0 and higher. Older models (2017 and earlier) do not have built-in support and require third-party apps or set-top boxes (Apple TV, Chromecast).
