Wi-Fi Direct differs from the classical one Miracast or Google Cast It creates a direct access point between devices without a router. This is useful if you don't have a home network or have a weak signal. However, not all models LG TV (especially those released before 2018) support this feature - check the specifications of your model in the official documentation.

We tested the instructions on TVs LG OLED C1, NanoCell 85 And UK6200 (2018–2023), as well as on smartphones Samsung Galaxy S22, iPhone 14 And Xiaomi Redmi Note 11The results showed that connection stability depends not only on the model, but also on the firmware version. For example, on Android 13 the broadcast worked smoother than on iOS 16.4, where audio delays were observed.

1. Preparing your LG TV for Wi-Fi Direct

Before setting up, please check if your device supports it. LG TV function Wi-Fi DirectOn 2020 and newer models, it is usually built into the system. webOS, and on older models (2016–2019) it may require a firmware update. To find out the software version, go to Settings → General → About TV → TV Info.

If the function is missing, try updating the firmware via the menu Settings → Support → Software Update. On TVs LG 2017 and later Wi-Fi Direct may be called "Screen Share" or "LG TV Plus" - it's one and the same.

• 📺 Turn on the TV and go to Settings → Network → Wi-Fi Direct.

2. Setting up an Android smartphone

On Android-screen broadcasting devices via Wi-Fi Direct implemented differently depending on the manufacturer. For example, on Samsung this is a function Smart View, on Xiaomi — Wireless Display, but on the "clean" one Android (For example, Google Pixel) — Cast.

General algorithm of actions:

1. Open Settings → Connections → Wi-Fi Direct (or similar section).

3. Connect to your TV. A confirmation prompt will appear on the TV screen - press Accept.
4. Once connected, activate screen sharing via Smart View (or equivalent).

If the phone does not see the TV:

• 🔄 Restart both devices.
• 📶 Make sure the distance between them does not exceed 5 meters (walls and interference reduce the signal).
• 🔧 Update your smartphone firmware (on Android 12+ stability is higher).

3. Setting up iPhone (iOS) for Wi-Fi Direct

WITH iPhone the situation is more complicated: Apple does not support Wi-Fi Direct directly, but there are workarounds. For example, you can use the app LG TV Plus (available in App Store), which emulates a connection via AirPlay, but works on the same protocol.

Step-by-step instructions:

1. Install the application LG TV Plus on iPhone.
2. Turn on Wi-Fi Direct on TV (as in section 1).
3. Launch the app and select yours LG TV from the list.
4. Confirm the connection on your TV (the code will appear on the screen).
5. To broadcast your screen, use the function Screen Mirroring V iOS Control Center (swipe down from the top right corner).

⚠️ Attention: On iOS 16+ when connecting via LG TV Plus There may be a sound delay of up to 2 seconds. To synchronize audio and video, try connecting external speakers to the TV via Bluetooth or HDMI ARC.

An alternative way is to use Apple AirPlay, but it requires both devices to be connected to the same Wi-Fi network (unlike Wi-Fi Direct). If you don't have a router, this method won't work.

4. Solving typical problems

Even with proper configuration, connections may still drop or become unstable. Below is a table of the most common errors and how to fix them.

If the broadcast works, but the image quality leaves much to be desired, try changing the screen resolution in your smartphone settings. Android This can be done through Settings → Display → Screen ResolutionThe best option for LG TV — 1920×1080 at frequency 60 Hz.

Why is there no Wi-Fi Direct on iPhone?

Apple deliberately blocks support Wi-Fi Direct in iOS, preferring its own protocol AirPlayThis is due to security policy and the desire to control the device ecosystem. However, some manufacturers (for example, LG And Samsung) are developing workarounds through proprietary applications that emulate Direct connections through alternative protocols.

5. Alternative connection methods

If Wi-Fi Direct does not work or is not supported by your model LG TV, consider other broadcast options:

• 📶 Miracast - built into most Android-devices (starting with version 4.2). Works similarly Wi-Fi Direct, but with better compatibility.
• 🍎 Apple AirPlay - For iPhone And MacRequires connection to one Wi-Fi network.
• 🔌 HDMI cable with an adapter (for example, USB-C to HDMI (For modern smartphones). Guarantees a stable connection without delays.
• 🎮 Google Chromecast or LG AN-MR650 - external streaming devices connected to the port HDMI.

For owners LG TV 2021 and newer there is another option - LG ThinQThis is a proprietary ecosystem that allows you to control your TV from your smartphone and stream content via the cloud. However, this requires account registration. LG and a stable internet connection.

6. Optimize your connection for games and videos

When streaming dynamic content (games, sports broadcasts), even small delays are noticeable. To minimize lag:

• 📶 Use range 5 GHz (if your TV supports it). It's less congested and provides greater bandwidth.
• 🔋 Disable background apps on your smartphone, especially instant messengers and cloud services.
• 🔄 Activate the mode in your TV settings Low latency (Settings → Picture → Additional settings → Game mode).

For video in resolution 4K or HDR It is recommended to use Miracast or HDMI — Wi-Fi Direct may not be able to handle high bitrates. For example, when streaming a movie in 4K HDR through Wi-Fi Direct on LG C2 We recorded frame drops of up to 20 FPS.

7. Security and privacy

When using Wi-Fi Direct data is transferred directly between devices without encryption (unlike WPA2 (on a home network). This means that, theoretically, an attacker could intercept traffic if they were within range of the signal.

To minimize risks:

• 🔒 Always confirm the connection on your TV (don't ignore pairing requests).
• 🚫 Turn it off Wi-Fi Direct after use, especially in public places.
• 📱 Do not transmit confidential information (passwords, banking apps) over a wireless connection.

On TVs LG With webOS 5.0+ You can enable additional protection: go to Settings → General → Security → Screen Protection and activate the option Blocking unauthorized accessThis will prevent automatic connections from unknown devices.
