Broadcasting a smartphone screen onto a big TV screen is a convenient feature for watching videos, games or presentations. But when it comes to connecting devices from different brands (Xiaomi and Samsung), users often face compatibility problems. In this article, we will discuss all the current ways of connecting, including wireless technologies and wired solutions, and also explain how to avoid typical errors.
Itโs important to understand that streaming methods depend on your Samsung TV model (QLED, Crystal UHD, The Frame, etc.) and Xiaomiโs MIUI firmware version. For example, older TVs without Smart View donโt support live Wi-Fi Direct, and smartphones with MIUI 12 and later have Miracast restrictions due to security policies. We tested all methods on current devices (2023-2026) and put together working solutions.
If you need to get your phone to the screen right away, start with the Smart View section, which is the most versatile method. For gamers or those who care about minimal latency, HDMI will do, and if you have a TV without Smart features, read about adapters at the end of this article.
Preparation of devices before broadcasting
Before you start setting up, make sure that both devices meet the minimum requirements:
- ๐ฑ Smartphone Xiaomi: version MIUI 10 and higher (older firmware may not work Miracast). โ The phone.
