Do you want to show pictures from your vacation on the big screen, run a mobile game on your TV or stream a movie with Xiaomi without losing quality? Smartphone screen transmission on TV is one of the most popular features, but not everyone knows how to do it correctly. In this article, we will discuss all the current ways for Redmi, POCO and Mi devices (including models from 2023-2026), from wireless protocols to wired adapters, taking into account the features of MIUI and HyperOS firmware.
The main problem with users is unstable connection, image delays or lack of sound. Not only will we give step-by-step instructions, but we will also explain why some methods do not work on your model, how to circumvent manufacturer restrictions and what settings to optimize for smooth broadcasting. For example, did you know that Miracast is disabled by default on the Xiaomi 13 Pro with HyperOS and needs to be activated manually through the engineering menu?
At the end of the article, you'll find a comparative table of all the ways in terms of speed, quality and compatibility, as well as answers to common questions, from solving the black screen problem to adjusting the sound when broadcasting via HDMI.
1. Wireless streaming via Miracast (built into MIUI)
Miracast is a wireless screen transmission standard supported by most modern TVs (Samsung, LG, Sony, Xiaomi TV) and Xiaomi smartphones since the Redmi Note 5. The main advantage is that there is no dependence on the Internet: the connection is established directly between the phone and TV over Wi-Fi Direct.
To begin the broadcast:
- ๐ฑ On the phone: open Settings โ Connection and sharing โ Screen transfer (to HyperOS path may differ: Settings) โ Screen. โ Wireless display).

2. Streaming via Google Cast (Chromecast, Android TV)
If your TV is running Android TV (e.g. Xiaomi Mi TV 4S/5, Sony Bravia) or connected to Google Chromecast, use Google Cast protocol. Unlike Miracast, here the phone sends content (video, photos, music) rather than duplicate the entire screen.
Instructions:
- Make sure your phone and TV are connected to the same Wi-Fi network.
- Open a supported app (e.g. YouTube, Google Photos, Netflix).
- Slip on the Cast icon (๐ก) and choose your TV.
To duplicate the entire screen:
- Go to Settings โ Connected devices โ Connect to the device.
- Select Screen Broadcast and find the TV in the list.
โ ๏ธ Note: On Xiaomi phones with HyperOS (e.g. Xiaomi 14), Google Cast may conflict with Miracast. Turn off Miracast in the wireless display settings before connecting.
List of apps that support Google Cast:
| Category | Annexes | Features |
|---|---|---|
| Video | YouTube, Netflix, KinoPoisk | Supports 4K HDR with stable Wi-Fi |

| Games | NVIDIA GeForce NOW, Xbox Cloud Gaming | Delay ~100 ms (not suitable for shooters) |
3. a wired connection through HDMI-adapter (without delay)
If you want maximum quality (4K/60fps, HDR) or stable broadcast for gaming, use a wired connection via a USB-C โ HDMI adapter.This method works on all Xiaomi models, including the Redmi Note 12 and POCO F5.
What you need:
- ๐ adapter USB-C to HDMI (We recommend models with DisplayLink chip for support 4K).
- ๐บ HDMI-cable (version 2.0 or higher) 4K).
- โก Power supply for the phone (broadcast drains the battery in 1-2 hours).
Step-by-step:
- Connect the adapter to the USB-C port of the phone.
- Connect the adapter to the TV via HDMI.
- On the TV, select the appropriate HDMI-entrance.
- The phone may be asked to allow the transfer of the screen โ confirm.

4. Broadcast via Wi-Fi Direct (for old TVs)
If your TV doesnโt support Miracast or Google Cast (like pre-2018 models), try Wi-Fi Direct, which creates a direct network between your phone and TV, but has limitations:
How to connect:
- On the TV, activate Wi-Fi Direct (on the network menu).
- On Xiaomi phone, go to Settings โ Wi-Fi โ Wi-Fi Direct.
- Select the TV from the list and confirm the connection.
- Run the stream via the Mi Remote or LocalCast app (available on Google Play).
โ ๏ธ Note: When using Wi-Fi Direct, your phone will not be able to connect to the Internet at the same time. To stream online videos (such as YouTube), first download the content to your device.
Limitations of Wi-Fi Direct:
- ๐ Maximum authorization โ 720p (sometime โ 1080p artifact-like).
- ๐ต The sound is transmitted separately (may be unsynchronized with the video).
- ๐ข Latency up to 300 ms - unsuitable for gaming.

5. Use of third-party applications (ApowerMirror, TeamViewer)
If the built-in methods don't work, try specialized applications that are suitable for broadcasting on Windows/Mac and then output to TV or to bypass firmware restrictions.
Top.-3 apps:
