How to Connect a Huawei Tablet to an LG TV via Wi-Fi: A Step-by-Step Guide

Wireless connection of the tablet Huawei to the TV LG Wi-Fi opens up the possibility of streaming movies, games, and presentations without the hassle of wires. However, many users encounter compatibility issues, connection errors, or an unstable signal. This article will help you understand the nuances of setup, choosing the optimal method depending on your device models and software versions.

We will look at three main ways of connecting: through built-in functions screencasting, technology Miracast and a branded application LG Smart ShareEach method has its own characteristics, from data transfer speed to audio support. It's important to keep in mind that some models Huawei (for example, series MatePad Pro or MediaPad M5) may require additional settings, and TVs LG on webOS older than 2018 sometimes do not support modern protocols.

Before you begin, make sure both devices are connected to the same Wi-Fi network with a frequency 2.4 GHz or 5 GHz (the latter is preferable for stability). If your router supports guest mode, temporarily disable it - this is a common cause of device detection failures.

1. Preparing devices: what to check before connecting

Before setting up the connection, you need to make sure both devices meet the minimum requirements. Let's start with the tablet. Huawei:

• 📱 EMUI/HarmonyOS version: For stable operation of screencasting it is required EMUI 9.0 or newer (for HarmonyOS - any version). You can check it in Settings → About phone.
