Connecting Xiaomi’s smartphone to Samsung’s Smart TV opens up new possibilities, from viewing photos on the big screen to streaming games with minimal latency. However, users often face compatibility problems – especially when it comes to different ecosystems (MIUI and Tizen OS). In this article, we will analyze all the current ways of connecting (including hidden features), compare them in speed, quality of transmission and stability, and also provide solutions for typical errors like “device not found” or “no sound”.
Many people think that a single Wi-Fi or HDMI cable is enough to connect, but in practice, the choice of method depends on the phone model (Xiaomi 13 Pro vs Redmi Note 10), Samsung’s firmware version (2020-2026), and even the router used. For example, Samsung’s QLED 2023+ TVs only support Miracast through the company’s SmartThings app, not through the standard menu. We tested each method on real devices and highlighted key nuances.
