Synchronizing a Xiaomi smartphone with an LG TV opens up a lot of possibilities, from streaming high-resolution video to using the TV as a second screen for games or presentations. However, many users face problems โ devices can not find each other, connection breaks or image slows down. In this article, we will analyze all the current ways of connecting (including hidden MIUI and webOS functions), and also give a checklist to eliminate typical errors.
Itโs important to consider that the connectivity methods depend on the LG TV model (e.g., the OLED C2 series is configured differently than the budget NanoCell) and the Xiaomi version of MIUI. We tested the instructions on devices with MIUI 14 and webOS 23, but most of the methods work on older versions as well. If your TV is released before 2018, check out the alternatives section, which describes workarounds for legacy software.
Before you start, check two key points: 1. Both devices are connected to the same Wi-Fi network (for most methods). 2. The LG TV has Screen Share enabled (in the Settings menu โ Connect โ TV screen).
If one of the conditions is not met, further action is meaningless.
1. Connecting via Wi-Fi Direct (Miracast) is the most versatile way
Miracast technology (or Wi-Fi Direct in LG terminology) allows you to broadcast Xiaomi screen to a TV without wires and additional devices, this method works on all Xiaomi smartphones with MIUI 10 and later, as well as on LG TVs with webOS 3.0+ (released after 2016).

2.Using the Smart Share (LG SmartThinQ) function
If Miracast doesnโt work or you want to broadcast only media files (photos, videos, music), use LGโs SmartThinQ app, which allows you to control your smartphone content directly from the TV remote, which is suitable for LG models with webOS 4.0+ (2019 and later).
Instructions:
- Install LG SmartThinQ from Google Play on Xiaomi.
- Register an LG account (or sign in if you already have one).
