Mirror your iPhone's screen to your TV (Screen Mirroring)

The most versatile way to mirror an image is to use Screen Mirroring. This action completely replicates the contents of your smartphone's display on your TV, including the iOS interface, notifications, and home screens. Open Control Center on your iPhone (swipe down from the upper-right corner or swipe up on older models).

Click the "Screen Mirroring" icon, which looks like two overlapping rectangles. Select your TV from the list of available devices that appears. LGIf you've set up a passcode, a 4-digit code will appear on your TV screen that you'll need to enter on your iPhone.

After successful pairing, the image from the phone will appear on the full screen. It is important to rememberIn this mode, your phone won't lock, and all notifications will be visible on the big screen. To stop broadcasting, open Control Center again and tap "Stop Repeating," or simply select the icon on the lock screen.

What to do if the screen goes black?

If you connect and see a picture but no sound, or the screen is black, check your video format settings. Some apps block the output of protected content via AirPlay due to licensing restrictions (HDCP).

Stream videos and photos from apps

A more energy-efficient option is to use the built-in cast button within apps like YouTube, Netflix, Vimeo, or Photos. This way, the TV streams data directly from the network, offloading the iPhone's processor and saving battery life.

Find the AirPlay icon (rectangle with a triangle at the bottom) or the "LG Connect" logo in the app. Tapping it will select the target device. Unlike full screen mirroring, you can minimize the app on your phone, reply to messages, or even turn off the smartphone screen—and playback on the TV will continue.

The quality of the transmitted video is often higher in this mode, as the TV decodes the stream itself, supporting formats up to 4K and HDR, if the model supports it. The process for the photo gallery is similar: open a photo, tap "Share," and select AirPlay to display a slideshow.

Using the LG ThinQ app to control

If standard methods are unstable or you need advanced functionality, use the official app. LG ThinQIt's available in the App Store and allows you to not only stream media files but also use your phone as an advanced remote control with a keyboard for text input.

After installing the app and registering an account, click "+" to add a device. The app will automatically find the TV on your local network. Once paired, select "Cast" or "Screen Share" in the app interface.

The advantage of this method is the ability to transfer files in various formats not supported by the native AirPlay player. Additionally, ThinQ can be used to control volume and navigate the Smart TV menu, which is convenient if the main remote is lost.

Troubleshooting connection and latency issues

The most common issue is when the iPhone simply doesn't see the TV in the device list. In this case, the first step is to reboot the router. The network services cache often gets full, and a simple restart restores the discovery protocols (Bonjour/mDNS).

If the issue persists, check your router's firewall or antivirus settings. Some IoT Protection or Guest Mode features may be blocking local communication between Apple and LG devices. Try temporarily disabling these features to test.

⚠️ Note: The webOS and iOS interfaces are updated regularly. The menu item layout may differ slightly from that described. If you don't find the option you need, use the search in your TV settings.

If you experience audio delays (desync between audio and video), try changing the delay mode in the AirPlay settings on your TV or disabling additional audio effects, such as AI Sound Pro, which can introduce lags when processing the signal.

Frequently Asked Questions (FAQ)

Is it possible to connect an iPhone to an old LG TV without Smart features?

Without a built-in Wi-Fi module and Smart TV, direct connection is impossible. You'll need to purchase an external set-top box (Apple TV, Chromecast, or Android TV box) that connects via HDMI and supports AirPlay.

Why is there no sound when connected, only a picture?

Check that your phone isn't set to silent mode, although sound should normally be present. Most often, the problem lies with the audio codec format, which isn't supported by the TV for direct mirroring. Try playing the video through YouTube or VLC, which have their own decoders.

Video is lagging when streaming from an iPhone. What should I do?

Reduce the video quality in the source app (e.g., from 4K to 1080p). Also, make sure no other devices are hogging the bandwidth by downloading large files. The 2.4 GHz Wi-Fi channel is often overloaded; switching to 5 GHz will solve the problem.

Does the operator charge for data transfer to the TV?

No, since the streaming is done within your home network via your router, it doesn't consume any internet traffic (if you're watching local files). If you're watching online videos, your data usage is the same as if you were watching them on your phone.
