How to connect Xiaomi phone to LG TV over Wi-Fi: all ways + problem solving

Wirelessly streaming a screen from a Xiaomi phone to an LG TV is a convenient way to show photos, videos, or even play on a large screen without wires. However, many users face problems: the connection is cut, the picture is laid, the TV simply “can’t see” the smartphone. In this article, we will discuss all the working ways of connecting (including hidden functions of MIUI and webOS), and also explain how to eliminate typical errors – from no sound to freeze the image.

It's important to understand that wireless broadcasting technologies are not just device models, but also firmware versions. For example, Xiaomi 12T Pro with MIUI 14 can support Miracast and Google Cast, and the old Redmi Note 8 can only support the first. The same goes for LG TVs: models 2020-2026 (on webOS 5.0+) are more stable than TVs 2018-2019. We tested instructions on combinations Xiaomi 13 Ultra + LG C2 and POCO X5 Pro + LG Nano86 — all methods worked, but with nuance.

If you've tried to connect and you've got an error like "Device failed" or "Device is not supported," don't blame the technology. 80 percent of the time, the problem is solved by setting up the router, updating the software or changing the broadcast protocol, and then step-by-step guides with pictures (for clarity) and a compatibility table.

1. Device Preparation: What to Check Before Connecting
