Many users of the Apple ecosystem are faced with the desire to display an image from their iPhone to the large screen of a Xiaomi or Mi TV. Often there is a misconception that it is enough to simply connect devices with a standard Lightning or USB-C charging cable. However, a direct connection via a USB port does not always provide video transmission without additional hardware or software intermediaries. iOS has a closed architecture, which requires a specific approach to organizing multimedia streaming.
Unlike Android devices, which often support MHL or DisplayPort Alt Mode out of the box via USB-C, iPhones require the Lightning Digital AV Adapter or wireless technology. However, physical cable connectivity remains the most stable way to transfer data, especially when minimal signal latency is important or there is no reliable Wi-Fi network. Understanding the technical nuances will help avoid frustration when trying to duplicate the screen.
In this article, we will discuss all possible options for physical connection, including the use of adapters, and also discuss software synchronization methods, which are often confused with direct connection. USB-You'll learn why simply inserting a cable into a TV port isn't enough and what components are needed to make the iPhone bundle work. + Xiaomi TV.
Technical limitations of direct USB-connection
The first thing that the user needs to realize is the fundamental difference in purpose. USB-ports on Xiaomi TVs.

The connection process is as follows: the adapter is inserted into the iPhone connector, a cable is connected to the adapter. HDMI, second end HDMI-The cable is inserted into the corresponding port on the Xiaomi TV. USB-Lightning is used only as part of the adapter, providing data and power, but does not directly connect devices to the cable».
After the physical connection, switch the signal source on the TV. To do this, on the Mi Remote remote, click the source select button (often indicated by a square with an arrow or a separate Input button) and select the HDMI 1 or HDMI 2 port into which the adapter was connected.
- 🔌 Stability: Wired connection via adapter eliminates delays typical of Wi-Fi, ideal for dynamic gaming.
- 🔋 Power: The adapter has an additional Lightning port for charging, as the broadcast process is energy intensive.
- 📺 Quality: Permission is maintained until 1080p HD, Providing a clear picture on Xiaomi matrices.
Software setting of the Xiaomi TV

For advanced users, there is the possibility of installing file sharing apps on the TV (for example, Send Files to). TV), which use a local area network but are initiated through QR-codes or web interfaces, again bypassing direct physical data transfers over the USB-cable.
Set up AirPlay wireless broadcast on Xiaomi
Because it's direct. USB-Connection to display images is impossible without expensive adapters, the most popular method is the technology AirPlay. Xiaomi TVs often have built-in support for this protocol, or it is implemented through a pre-installed application Mi Video or Mi Home.
