Modern technologies make it possible to transform the living room into a full-fledged multimedia center, where content from a smartphone instantly appears on the big screen. iPhone 7 and televisions LG People often look for a way to sync these devices to view photos, videos, or play games comfortably. Wireless Wi-Fi connection is the most convenient and aesthetically pleasing solution, eliminating unnecessary cables and distance limitations.
The setup process may seem complicated due to differences in operating systems. iOS And webOSHowever, modern data transfer protocols have significantly simplified this task. You don't need to be a networking expert to establish a stable signal transmission. The main thing is to understand the principles of a local network and correctly configure the settings of both devices.
In this article, we'll take a detailed look at all available connection methods, from native Apple features to third-party apps. We'll also explore the nuances of how they work. AirPlay 2, protocol features DLNA and specific router settings that can affect streaming quality. Carefully following the instructions will help you avoid common mistakes and enjoy high-definition content.
Checking compatibility and preparing equipment
The first step before starting setup is to make sure your hardware supports the required features. iPhone 7 Equipped with an 802.11ac Wi-Fi module, which provides high data transfer speeds sufficient for streaming 4K video. TVs LG Smart TV They must also support wireless connectivity, which is true for most models released after 2014.
A critical requirement is that both devices are on the same local network. This means that router It should distribute a signal that both your phone and TV are connected to. If you have a dual-band router, make sure both devices are connected to the same frequency (e.g., 2.4 GHz or 5 GHz), although modern routers often combine them into a single network.
⚠️ Note: If your router is configured with AP Isolation, devices will not see each other. This feature must be disabled in the router settings.
It's also worth checking the software version on your TV. LG This is done through the menu Settings → All settings → General → About TV → Check for updatesFor a smartphone, the path looks like this: Settings → General → Software UpdateCurrent OS versions contain important fixes for protocols. AirPlay And DLNA.
Using built-in AirPlay 2 support
Starting with the 2018-2019 models, many TVs LG received native support for the technology AirPlay 2This is the easiest and highest quality way to stream images, as it's built directly into the Apple ecosystem.

The advantage of this method is the ability to stream not only the picture but also high-quality audio, as well as control playback directly from your phone. However, if your TV model was released before 2018, this method may not be available, and you'll have to resort to alternative solutions.
Setting up Smart Share and DLNA protocol
For older models LG or situations where AirPlay doesn't work, the technology is ideal DLNA, implemented in the application Smart ShareThis protocol allows you to transfer multimedia files (photos, videos, music) over a local network. Unlike screen mirroring, you select a specific file to play.

☑️ Check before connection
Using third-party apps for broadcasting
If built-in methods aren't suitable, universal translator apps come to the rescue. The leader in this niche is LG TV Plus (official) or popular third-party solutions like Replica And TV CastThey create a software bridge between iOS and webOS, emulating the operation of native protocols.
Application LG TV Plus It not only allows you to stream content but also use your smartphone as a remote control.

⚠️ Please note: Free versions of third-party apps often have session time limits or contain ads. A subscription may be required for continued use.
It's important to understand that using third-party apps puts a strain on your phone's processor, which can lead to the device overheating and increased battery consumption. Wi-Fi module In constant data transfer mode, it also works more intensively, so keep an eye on the temperature of the gadget.
Why might the broadcast not work?
A common cause is your router's power-saving settings. Some routers aggressively turn off sleeping devices or block multicast packets needed to find DLNA devices. Try rebooting your router.
Streaming video from browsers and streaming services
Streaming content from the internet deserves special attention. If you're watching videos in a browser, Safari or through streaming service apps (YouTube, Netflix, ivi), the connection mechanism is different. Here, the technology used Cast or built-in players.
In the appendix YouTube Just click on the broadcast icon (rectangle with waves) in the corner of the video and select yours LG TVThe video will start playing directly on the TV, using its internet connection, freeing up your phone. This ensures the best picture quality and no lag.

However, some services (e.g., Netflix) may block mirroring due to copyright protection. HDCP, showing a black screen instead of video. In such cases, only the native app on the TV helps.
Solving common connection problems
Even with proper setup, issues may still occur. If the TV isn't visible in the list of devices, try restarting both devices. Often, the problem lies in a frozen network module on the TV. It's also worth checking whether guest Wi-Fi mode is enabled on the router—devices on the guest network are isolated from the main network and cannot communicate with each other.
If the image is choppy or the audio lags behind the video, this indicates a weak signal. Move closer to the router or remove any physical obstructions. Range Usage 5 GHz It is preferable for video transmission as it is less congested and provides more bandwidth than 2.4 GHz.
In some cases, resetting network settings on your iPhone can help. Go to Settings → General → Transfer or reset iPhone → Reset → Reset Network SettingsThis will delete saved Wi-Fi passwords, but often resolves issues with device discovery protocols.
⚠️ Note: TV interfaces and iOS versions are updated regularly. The menu item layout may differ from what's described. If you can't find the option you need, use the search in your TV settings.
Why can't my iPhone 7 detect my LG TV?
Most often, the devices are on different networks (for example, one is connected to 2.4 GHz and the other to 5 GHz with isolation, or one is on guest Wi-Fi). The issue may also be due to outdated TV firmware that doesn't support modern Bonjour/AirPlay discovery standards. Check if Smart Share is enabled in the TV menu.
Is it possible to connect an iPhone to an LG without Wi-Fi?
Wireless connection is impossible without a Wi-Fi router or access point. AirPlay and DLNA technologies require a local network. A wired connection (Lightning to HDMI) is possible, but requires a special adapter and is not a wireless method.
The sound is delayed during the broadcast, what should I do?
Audio lag often occurs when using third-party mirroring apps. Try using native AirPlay 2 if your TV model supports it, or stream content through built-in apps on your TV (YouTube, Netflix) rather than screen mirroring.
Does connecting an iPhone affect internet speed?
When mirroring your screen (AirPlay), your phone actively uses Wi-Fi to transmit the video stream, which can reduce the available speed for other devices on the network, especially in the 2.4 GHz band. When broadcasting via Cast (YouTube), the load on your phone is minimal.
