Broadcasting from Xiaomi phone to TV via USB: the full guide

You want to bring the screen of the Xiaomi smartphone to a large TV, but at hand only USB-It's real -- without Wi-Fi, without Miracast, without any adapters. USB-port, including hidden functions of the TV Universal solutions for all TVs.

The main problem with this connection is that most TVs today do not support direct USB video transmission in MHL mode (as they used to). However, Xiaomi has workarounds: from using the TV as a monitor over USB-C → HDMI to programmatic broadcasting via Mi Share with a USB cable as a physical bridge. We tested all methods on Redmi Note 12 Pro+ models, POCO X5 Pro and Mi TV P1/Mi TV Q2 – and we are ready to share the results.

Importantly, not all methods are equally effective. For example, direct image transfer via USB only works on Xiaomi TVs with a USB-C port, and the rest will require an adapter. But there are universal solutions - read on.

Direct USB-C connection → HDMI (only for Mi TV with USB-C)

This is the easiest way, but it only works on Xiaomi TVs with a USB-C connector (like the Mi TV Q2 75" or Mi TV P1 65").You'll need a USB-C → USB-C cable (better the original one from Xiaomi with DisplayPort Alt Mode support).

How it works:

• 🔌 Connect one end of the cable to the phone, the other to the port USB-C TV-wise.
• 📱 On the screen of the smartphone will appear a notification: select the mode "Share image" (or HDMI).
• 📺 The TV will automatically switch to the signal from USB-Port – the screen is duplicated with resolution up to 4K@30Hz.

⚠️ Note: On some models POCO (for example, POCO F5) This mode may not be activated due to firmware limitations, in which case, try to enable debugging on the USB in the developer settings (Settings) → The phone. → Version. MIUI — press 7 times).

💡

If the image on TV twitches, try in the phone settings (Settings → Display → Screen resolution) to reduce the resolution to 1080p.

2.Use of USB-Wi-Fi cable as a bridge for Mi Share (Wi-Fi Direct)

If your TV doesn't support USB-C → HDMI, you can trick the system into plugging your phone into a USB and streaming it through Mi Share (the Miracast equivalent), a method that works on all Mi TVs and most Android TVs.

Instructions:

1. Connect your phone to the TV through normal USB-cable (file transfer mode).
2. On your phone, open Settings → Connection and Sharing → Mi Share.
3. Turn on Wi-Fi Direct on your TV (in Mi TV: Settings → Network → Wi-Fi Direct).
4. In the list of available devices, select your TV – the broadcast will begin automatically.

🔍 Why does it work? USB-The cable here acts as a "physical confirmation" of the connection, and the broadcast itself is over Wi-Fi Direct. This eliminates the latency problems that occur with a regular Miracast.

• 🔋 For budget models (Redmi) 10C, POCO M5) adapter with external power (otherwise the image will flash).
• 🎮 For gamers: Look for low latency adapters (latency) < 50 ms).

💡
