Modern technology allows you to transform ordinary content viewing into a full-fledged cinematic experience right in your living room. Video broadcast Moving from a mobile device to a big screen isn't just convenient; it changes the way you experience media. If you own an Apple smartphone and an LG TV, you're in luck: the ecosystems of these brands work seamlessly together.
To get started, you don't need complicated cables or additional adapters if your equipment supports wireless protocols. Smart TV from LG are equipped with the webOS operating system, which has built-in support for technology AirPlay 2This means you can mirror your screen or stream video from apps with just a few taps. However, to ensure a smooth process, there are a few important technical details to consider.
The main requirement for a successful connection is that both devices are on the same local network. Wi-Fi router It should correctly transmit data packets between devices without blocking. In this article, we'll cover all available connection methods in detail, review security settings, and answer frequently asked questions users may have when setting up streaming.
Preparing equipment and a Wi-Fi network
Before attempting to sync devices, you need to make sure that the foundation for the connection is laid properly. LG TV And iPhone must be connected to the same wireless network. Users often encounter a problem when the phone is connected to mobile internet (3G/4G/5G) while the TV is connected to home Wi-Fi. In this case, device detection is impossible.
Check your router settings. Some modern routers separate the 2.4 GHz and 5 GHz frequencies into different SSIDs (network names). If your phone is on one frequency and your TV is on another, they may not be able to "see" each other, despite sharing the same internet connection. Ideally, use a single network that supports both bands or force both devices to connect to the same frequency.
⚠️ Note: If you're using a guest Wi-Fi network enabled on your router, devices may be isolated from each other for security purposes. AirPlay and DLNA require client isolation to be disabled.
It's also worth updating your software. On your LG TV, go to the settings menu and check for system updates. On iPhone, make sure you have the latest version of webOS installed. iOSOlder firmware versions may contain bugs that prevent a stable connection via the Bonjour protocol, which is used to search for devices on the network.
Using the built-in AirPlay 2 feature
The easiest and highest-quality way to display an image is to use Apple's native technology. LG models released in 2019 and later, as well as some earlier versions after an update, support AirPlay 2. This allows you to stream videos, photos, and even mirror your smartphone's entire screen without delays or loss of quality.
To activate this feature on your LG TV, press the "Home" button on the remote, find the "Apple AirPlay" app, or go to the connection settings. Make sure the feature is enabled. On your iPhone, open "Control Center" (swipe down from the upper-right corner or up from the bottom, depending on the model). Tap the "Screen Mirroring" icon (two rectangles).
From the list of available devices, select yours LG TVA confirmation code may appear on the TV screen. Enter this code on your iPhone to establish a trusted connection. The image from your phone will then appear on the big screen. You can rotate your phone to landscape mode, and the image will fill the entire screen.
- 📱 Open Control Center on your iPhone and tap Screen Mirroring.
- 📺 Select your LG TV from the list of available devices.
- 🔢 Enter the confirmation code if it appears on the TV screen.
- 🎬 Launch a video in the app or open a photo to view.
If you use streaming apps like YouTube, Netflix, or IVI, the player often has a dedicated streaming button (a square with waves). Pressing it allows you to control playback from your phone while the TV streams content directly from the internet, saving your smartphone's battery.
Streaming via the LG TV Plus app
If built-in AirPlay doesn't work for some reason, or your TV model doesn't support this protocol, you can use the manufacturer's proprietary app. LG TV Plus (formerly known as LG Remote) turns your smartphone into a remote control and media center. This solution operates using the DLNA protocol.
Download the app from the App Store and install it. When you first launch it, it will automatically scan the network and find your TV. You'll be asked to confirm the pairing on the TV screen. Once successfully connected, go to the "Media" or "Gallery" section within the app.
Here you can select photos or videos saved on your iPhone and send them to your TV. Please note that this method doesn't allow you to mirror the entire screen (for example, displaying the Safari interface or games). It's intended solely for browsing your media library. Compression quality may differ from AirPlay, but it's sufficient for viewing your family's archive.
| Function | AirPlay 2 | LG TV Plus (DLNA) | Third-party applications |
|---|---|---|---|
| Screen mirroring | Yes | No | Partially |
| Video quality | High (HD/4K) | Depends on the file | Average |
| Delay | Minimum | Absent | High |
| Control from your phone | Complete | Complete | Limited |
Using the official app guarantees stable operation, as the data transfer protocols have been optimized by the company's engineers. However, functionality may be limited compared to native iOS tools.
Using third-party repeater applications
In situations where standard methods fail, intermediary applications come to the rescue. Programs like Replica, TV Cast or Web Video Caster Allow you to stream screen content or web pages to your TV. They often use proprietary compression and video streaming algorithms.
The principle is simple: you install the app on your iPhone, and on your LG TV (through the LG Content Store), you may need to install a companion app, although many work through the TV's built-in browser. Once connected, you choose what you want to show: a browser tab, a file from your file manager, or the entire screen.
⚠️ Please note: Third-party apps can put additional strain on your smartphone's processor, causing the device to overheat. Furthermore, free versions often contain ads, which will also be displayed on your TV screen.
The unique feature of these solutions is their versatility. They can even work with devices that don't formally support AirPlay, emulating the signal. However, lag can be noticeable, making them unsuitable for fast-paced games but perfectly suitable for presentations or slideshows.
Why might the video be lagging?
Lag often occurs due to Wi-Fi congestion. If the router is simultaneously distributing internet to several devices and downloading torrents, the bandwidth may not be sufficient to transmit a high-definition video stream in real time.
Adjusting image and sound settings
Once successfully connected, it's important to properly configure the media output. When mirroring your iPhone, the aspect ratio often remains the same, resulting in black bars around the edges of the image on your TV. To fix this, use the scaling feature on your LG TV. Press the "Zoom" or "Aspect Ratio" button on the remote and select "Just Scan" or "16:9" mode.
The sound may also require adjustment. If you only hear sound from your phone when connecting via AirPlay, check the audio output settings in Control Center. If using DLNA, make sure your TV isn't in "Mute" mode and the volume is sufficient. Some LG models allow you to adjust the volume for media content and system sounds separately.
For those who appreciate high-quality audio, it's important to know that AirPlay 2 supports multichannel audio. If you have an external speaker system or soundbar connected to your TV, the audio will be transmitted at a high bitrate. In your TV settings, under "Sound," select "Auto" or "Hi-Fi" for the best results.
- 🖼️ Use the "Just Scan" mode on your TV to remove cropping from the edges of the picture.
- 🔊 Make sure that your iPhone settings are set to output audio to the TV, not to the phone speaker.
- 🌙 Turn off notifications on your iPhone ("Do Not Disturb") to prevent messages from interrupting your movie.
Please keep in mind that your TV screen brightness may differ from your phone's settings. For comfortable viewing in the dark, we recommend switching your TV to "Cinema" mode, which has a warmer color temperature.
Troubleshooting connection and stability issues
Even the most perfectly configured network can sometimes experience glitches. If your TV isn't detecting your iPhone, first try restarting both devices. This is a classic but effective method for clearing the network service cache. Unplug your TV for 10 seconds, and then restart your iPhone using the menu.
The issue may lie in your router's firewall settings or your PC's antivirus software if it's sharing Wi-Fi. Ensure that the Bonjour ports (UDP 5353) are open. Also, check that Cellular Data isn't enabled on your iPhone while Wi-Fi is disabled—in some iOS versions, this can block the search for local devices.
☑️ Connection diagnostics
If the connection drops while watching, check the signal strength. TVs often have weaker Wi-Fi modules than smartphones, especially if they are located far from the router or behind the screen (the metal back of the TV can block the signal). In this case, using a Wi-Fi repeater or connecting the TV via a LAN cable, if possible, may help.
⚠️ Please note: Operating system interfaces and TV menus are subject to update. The location of menu items or function names may differ from those described in the instructions. Always refer to the latest user manual on the manufacturer's official website.
Frequently Asked Questions (FAQ)
Is it possible to connect an iPhone to an LG TV without Wi-Fi?
Yes, this is possible with a wired connection. You'll need a Lightning to HDMI adapter (or USB-C to HDMI for newer iPhone models) and an HDMI cable. This ensures the best picture quality and the absence of lag, as the signal is transmitted directly, bypassing the wireless network.
Why isn't my LG TV showing up in the AirPlay list?
Most often, the problem is that the devices are on different networks (for example, one on 2.4 GHz and one on 5 GHz with different names). Also, check that AirPlay is enabled in the LG TV settings. Sometimes, temporarily disabling the VPN on your smartphone helps.
Video is lagging when streaming from iPhone to TV. What should I do?
Try lowering the video quality in the source app (for example, from 4K to 1080p). Make sure no other devices are downloading large files. If the issue persists, reboot your router.
Do older LG TVs support AirPlay?
Official AirPlay 2 support was added to LG models from 2019 and later (OLED, NanoCell, and UHD series). Older models can only work with third-party apps or the DLNA protocol, but lack native AirPlay.
