How to turn Miracast on your Xiaomi 4S TV: full error-solving instructions

Miracast is a technology that allows you to duplicate an image from your device to a large screen without wires and additional adapters using direct communication over Wi-Fi Direct. Unlike DLNA (which broadcasts only media files) or AirPlay (works only with Apple devices), Miracast supports full screen mirroring with minimal latency – ideal for games, presentations or watching videos.

Xiaomi Mi TV 4S (all modifications including 4S 32, 43, 50, 55, 65" and 75") are equipped with built-in Miracast support, but the feature is often hidden in the depth of the menu or disabled by default.
