The display of images on the big screen of Xiaomi TV is a challenge faced by owners of smart TVs of this brand and users of other devices (smartphones, laptops, PCs). Despite the apparent simplicity, the process can be complicated by a variety of models (Mi TV 4A, Mi TV Q2, Redmi Smart TV), versions of the firmware of MIUI TV and types of connected devices. In this article, we will analyze all the current ways of transmitting images, from wireless protocols to wired connections, as well as typical errors and their solutions.
Xiaomi TVs are ambiguous in nature: they run on Android TV (premium model) or PatchWall (budget series) and affect the available screen duplication features. For example, the Mi TV P1 supports Google Cast out of the box, while the Redmi TV A2 may require manual Miracast tuning, and we have taken these nuances into account and prepared universal instructions that are relevant to most models in 2019-2026.
