Dubbing a screen on a Xiaomi TV is a convenient way to stream content from your phone, tablet or computer to the big screen. Whether it's watching movies, presentations, games or just showing photos, wireless or wired image technology saves time and makes multimedia interaction more comfortable, but not all users know how to set up duplication correctly, especially if it comes to different devices and communication protocols.
In this article, we will analyze all the current ways to duplicate the screen on Xiaomi Mi TV, Redmi Smart TV and other models of the brand – from classic HDMI connection to Miracast wireless technologies, AirPlay and Mi Share proprietary solutions. You will learn what settings you need to turn on the TV and signal sources, how to eliminate typical errors (for example, image delay or lack of sound), as well as what limitations each method has.
We'll focus on device compatibility: not all smartphones and laptops support duplicate on Xiaomi TV out of the box. For example, the iPhone will require additional adapters for wired connectivity, and older TV models may not support Miracast without a firmware update. To avoid disappointment, we've compiled a compatibility table and checklists to prepare the equipment.
1. Preparing Xiaomi TV for screen duplication
Before you connect an external device, you need to make sure that the Xiaomi TV is ready to receive the signal. Most of the duplication problems arise from disabled features or outdated software.
