Connecting the monitor to Xiaomiโs smartphone opens up new possibilities, from watching movies on the big screen to working with documents in multitasking mode. However, not all users know that modern devices Redmi, POCO and Black Shark support image output via USB-C, HDMI or wireless protocols. In this article, we will analyze all the current methods of connection, from wired adapters to Miracast and Mi Share technologies, and also explain how to avoid common errors.
Itโs important to understand that not every Xiaomi smartphone supports displaying images to an external display. For example, budget models Redmi 9A or POCO M3 do not have the DisplayPort Alt Mode function via USB-C, while flagships like Xiaomi 13 Ultra or Black Shark 5 Pro offer advanced features, including support for 4K@60Hz. We analyzed technical specifications and user tests to compile a compatibility checklist and detailed instructions for each method.
1. Check the compatibility of your Xiaomi smartphone
Before you buy adapters or set up a wireless connection, make sure your device supports image output.
- ๐ฑ Processor: Qualcomm Snapdragon chips 8xx (For example, Snapdragon 8 Gen 2 Xiaomi 13) MediaTek Dimensity 9000+ Almost always support DisplayPort Alt Mode.Budget Snapdragon 4xx/6xx โ often.
- ๐ Port port USB-C: Must maintain the standard USB 3.1+ (It's based on the data rate. USB 2.0 (e.g. Redmi Note 8) wired monitor connection is not possible.
- ๐ฅ๏ธ Version. MIUI: Starting with MIUI 12.5 adds built-in support for wireless screen duplication via Mi Share. Earlier versions may require third-party software.
Smartphones Xiaomi based on Snapdragon 7xx processors (for example, POCO X5 Pro with Snapdragon 778G) can support image output, but only with a resolution of up to 1080p@30Hz is a hardware limitation, and it can not be circumvented.
| Xiaomi model | Support USB-C โ HDMI | Max. resolution/frequency | Wireless duplication |
|---|---|---|---|
| Xiaomi 13 Pro | โ Yes. | 4K@60Hz | โ Miracast, Mi Share |
| POCO F5 | โ Yes. | 1440p@60Hz | โ Miracast |
| Redmi Note 12 Pro+ | โ Yes. | 1080p@60Hz | โ Mi Share |
| Black Shark 5 | โ Yes. | 4K@30Hz | โ No (required PO) |
| Redmi 10A | โ No. | โ | โ Only Miracast. |
If your model isnโt in the table, check the specifications on Xiaomiโs official website or use the DevCheck app (available on Google Play) to find out the USB-C port type and DisplayPort support.
2. Wired connection via USB-C โ HDMI
The most stable and versatile method is to use an adapter or cable that supports DisplayPort Alt Mode.

Common problems and solutions:
- ๐ No image: Try another cable or adapter. Cheap Chinese adapters often don't support 4K.
- โณ Delayed input (lag): For games, use adapters with USB 3.1 and cables not exceeding 1.5 m in length.
- ๐ No sound: In the smartphone sound settings (Settings) โ Select the sound HDMI output-wise.
๐ก
If the adapter doesnโt work with your Xiaomi, try connecting it through the phone. USB-externally powered hub, some models (e.g, POCO F4 GT) Require additional power source for stable operation of DisplayPort.
3. Wireless connection via Miracast
Miracast technology allows you to duplicate your smartphone screen on a monitor or TV wirelessly using Wi-Fi Direct.This method works on most Xiaomi devices, but has latency limits (up to 100 ms), making it unsuitable for gaming.
What you need:
- ๐บ Miracast-enabled monitor/TV (or adapter) HDMI โ Miracast, for example, Microsoft Wireless Display Adapter).
- ๐ถ Stable Wi-Fi 5 GHz (Lags are possible at 2.4 GHz).
- ๐ Charge of the smartphone at least 30% (wireless transmission consumes a battery).
Instructions for MIUI 13/14:
- On the monitor, activate Miracast mode (in the signal source menu).
- On your smartphone, open Settings โ Connection and Sharing โ Wireless display.
- In the list of available devices, select your monitor.
- Confirm the connection on both devices.
Features of Miracast on Xiaomi:
- ๐ฎ For games: 80-120 ms delay makes the method unsuitable for shooters or racing.
- ๐ถ Connection problems: If the monitor doesnโt appear in the list, restart the router and smartphone, then try again.
- ๐ Sound: Unlike wired sound, sound is transmitted automatically.
๐ก
Miracast on Xiaomi only works with monitors that support Wi-Fi Direct. If your TV is older than 2018, you will likely need an external adapter.
4.Using Mi Share to Duplication Screen
Mi Share is Xiaomiโs proprietary wireless screen technology, optimized for ecosystem devices (e.g. Mi TV or Redmi Smart TV). Unlike Miracast, it has less latency (50-70 ms), but only works with Xiaomiโs hardware.
How to connect:
