You no longer need to search for complicated adapters or HDMI cables if both devices are on the same network. This ensures maximum convenience and eliminates cable clutter in the living room.
In this article, we will examine in detail all available synchronization methods, starting from the built-in system functions iOS and ending with specialized apps. We'll cover the nuances of router setup, potential connection issues, and troubleshooting steps. Follow the instructions to enjoy high-quality content.
Preparing devices and checking the network
The first and most critical step is ensuring a stable connection between the devices. Both devices—and yours— iPhone, and TV LG — must be connected to the same Wi-Fi network. If you use a dual-band router, make sure both devices operate on the same frequency, preferably 5 GHz for high-definition video transmission.
Check your TV's software is up to date. On your TV, go to the Settings menu and find the updates section. For iOS devices, the path usually looks like this: Settings → General → Software UpdateOutdated firmware versions may not support modern data transfer protocols.
⚠️ Note: If your router is configured for AP Isolation, devices will not see each other. This feature is often enabled on guest networks for security.
Make sure Smart Share or a similar device discovery feature is enabled on your TV. Without this feature enabled in the TV's network settings, your TV will be hidden from external sources. This is a standard security measure to prevent unauthorized access to your screen.
Using the built-in AirPlay 2 feature
The highest quality and most stable translation method is available on models LG, released after 2018. Technology AirPlay 2 Allows you to transfer video, audio, and photos directly from standard applications. You don't need to install additional software, as the protocol is built into the system. iOS.
To start playback, open a video file or launch a streaming service on your phone. Find the AirPlay icon, which looks like a rectangle with a triangle at the bottom. Click it and select your TV from the list. LGIf prompted, enter the code displayed on the TV screen.

- 🔗 Click the "Screen Mirroring" button (two intersecting rectangles).
- 📡 Select your LG TV from the list of devices provided.
- ✅ Confirm the connection if an access request appears on the TV screen.
The quality of the transmitted image directly depends on the speed of your Wi-Fi Connection. A minimum bandwidth of 25 Mbps is recommended for viewing 4K content. If the signal is weak, the image may stutter or the resolution may automatically decrease.

Alternative streaming apps
There are many third-party solutions that can be even more effective than standard tools. Apps like Replica or TV Cast for LG They specialize in content delivery. They often have their own codecs, allowing them to play formats that aren't supported by the TV's native player.
Some services allow you to stream webpage content. You simply enter the video URL into the app's address bar, and it sends the stream directly to your TV, bypassing buffering on your phone. This saves battery life and reduces the load on your smartphone's processor.
⚠️ Note: Free versions of third-party apps often contain ads. Be careful when clicking on pop-ups while browsing.
When choosing software, pay attention to user reviews and the date of the last update. Developers should regularly maintain compatibility with new versions. iOS and firmware updates LG WebOSOutdated applications may become unstable or not connect at all.
Why are some videos not playing?
The video file format may not be supported by your TV. In this case, use converter apps or stream via a PC with a media server (DLNA) installed.
Setting up DLNA and local servers
For advanced users with a large movie collection on their computer or NAS storage, the ideal solution is DLNAIt allows you to organize your home media library, accessible to all devices on the network. Your LG TV will see your computer as a signal source.
On a Windows computer, open the media streaming settings. Make sure the network profile is set to "Private" and not "Public." Otherwise, the firewall will block the connection. Add the video folders to the list of shared resources.
On iPhone, use a client app that supports DLNA, such as VLC for Mobile or nPlayerThe app will detect your computer in the "Network" or "Local Area Network" section. Opening the folder will give you access to all files for playback on your TV.
☑️ DLNA Check
The advantage of this method is that there's no need to copy large files to your phone. You control playback from your smartphone, but the data goes directly from your computer to your TV. This ensures the best picture quality without compression.
Troubleshooting connection issues
Even with proper configuration, issues may still occur. The most common cause is desynchronization of IP addresses or the DNS cache. If the TV stops detecting your phone, try rebooting the router by completely unplugging it for 10-15 seconds. This will clear the routing table.
Another issue lies in your computer's antivirus or firewall settings if you're using a PC-TV connection. Security software may be blocking incoming connections from unknown devices. Add your TV and smartphone to the list of trusted devices.
- 🔄 Restart both devices (TV and iPhone) at the same time.
- 📶 Forget the Wi-Fi network on your phone and reconnect.
- ⏰ Check if the time and date are the same on all devices.
- 🛡️ Temporarily disable the VPN on your smartphone if it is activated.
If nothing helps, reset the network settings on your TV. In the menu Settings → All settings → General → Network Find the reset option. Remember that you'll have to re-enter your Wi-Fi password after doing this. This is a drastic, but often effective, method.
Why doesn't my LG TV detect my iPhone?
Most often, the devices are on different subnets (for example, one is connected to a guest Wi-Fi network and the other to the main network). Another possible cause is outdated router firmware that doesn't support multicast traffic, which is necessary for device discovery.
Is it possible to connect an iPhone to an old LG TV without Smart features?
Without a built-in Wi-Fi module, a direct connection is impossible. You'll need to purchase an external set-top box (Apple TV, Chromecast, or Android Box) that connects via HDMI and performs smart TV functions.
The sound is delayed during the broadcast, what should I do?
Audio lag often occurs when using third-party codecs or a weak router. Try lowering the video quality in the app settings or switching your TV to "Game" or "PC" mode in the picture settings, which reduces post-processing.
