Cast on Xiaomi: A Complete Guide to Wireless Screen Broadcasting

What is the Cast feature on Xiaomi devices and why you need it

If you've ever wanted to show pictures from a vacation on a big screen, stream a movie from your smartphone to your TV, or even duplicate a Xiaomi screen on a PC monitor, that's exactly what Cast is designed for. It's a technology that wirelessly transfers content between devices using Miracast, DLNA or Google Cast protocols, depending on your gadget model. In the Xiaomi ecosystem, it's integrated into both smartphones (Redmi, POCO, Xiaomi 13/14) and TVs (Mi TV, Redmi Smart TV), as well as smart speakers and projectors.

The main advantage of Cast is that there's no wires. You don't have to plug in. HDMI-cables or adapters: it is enough that both devices are on the same Wi-Fi network (or live streaming over Wi-Fi Direct), but here lies the first pitfall: not all content formats are transmitted equally well, DRM-Protected videos (like Netflix or Disney)+) They can get blocked on the broadcast, and high-graphics can slow down. Why this happens and how to get around it, we'll go through it.

It is important to understand that Cast on Xiaomi is not one universal feature, but a whole set of technologies:

• 📱 Screen Mirroring – full duplication of the smartphone screen on the TV (1:1).
• 🎬 Media Cast – Video/audio broadcast only (without phone interface).
• 🔄 Mi Share – Xiaomi’s proprietary protocol for fast file sharing between brand devices.

In this article, we will focus on the first two options, because they are the most popular: if you just want to throw a photo on the TV, Mi Share is good, and if you want to broadcast the whole screen (for example, for a presentation or streaming a game) you need Screen Mirroring.

What Xiaomi devices support Cast and what protocols do you use?

Not all Xiaomi gadgets work equally well with Cast. It all depends on the model, firmware version. MIUI/HyperOS And the following is the key device compatibility table:

Please note: if your Xiaomi smartphone is released before 2019 (for example, Redmi Note 7 or Mi 9), then for stable operation of the Cast, you may need to update the firmware to the latest version of MIUI 14 or HyperOS. Check the current version in the Settings menu → About Phone → MIUI version.

Another nuance: Xiaomi Android TVs (like the Mi TV A2 2026) support Google Cast out of the box, while PatchWall models (like the Redmi Smart TV X55) only support Miracast and DLNA. This affects compatibility with other brands, such as Samsung’s smartphone will not be able to stream a screen on Xiaomi TV through Miracast unless it is certified by the Wi-Fi Alliance.

How to turn on and configure Cast on Xiaomi smartphone: step-by-step instructions

Set up Cast on Xiaomi smartphones takes less than a minute, but there are a few hidden things that can save you time. For example, not everyone knows that you don’t need to connect to a single Wi-Fi network to stream to your TV — you can use Wi-Fi Direct. Let’s consider both options.

Method 1: Broadcasting over a shared Wi-Fi network (recommended)

This method is suitable for stable video and audio transmission without breaks. Make sure that both the smartphone and the TV (or other device) are connected to the same network.

Smartphone and TV connected to the same Wi-Fi network|Cast mode is on on the TV (Miracast/DLNA)|On the smartphone turned off the energy saving mode|Background applications that consume traffic are closed-->

2. Turn on the Broadcast slider (or Wireless Display on older versions of MIUI).
3. From the list of available devices, select your TV or Xiaomi projector. If the device doesn't show up, click Update list.
4. Confirm the connection on both devices (entry may be required) PIN-TV-screen code).

Once successfully connected, the smartphone screen will be duplicated on the TV. To broadcast only video (without the phone interface), open the app (like YouTube or Gallery) and click on the Cast icon (usually in the upper right corner).

Method 2: Direct Wi-Fi Direct (without router)

If you don't have Wi-Fi or the router doesn't support multicast, you can use Wi-Fi Direct, which is less stable, but it works in the field.

1. On Xiaomi TV, go to Settings → Network & Internet → Wi-Fi Direct and turn on the feature.
2. On your smartphone, open Settings → Wi-Fi → Wi-Fi Direct and select the TV from the list.
3. Once connected, go back to the Cast menu and select the TV manually (it can be displayed as DIRECT-xx:MiTV).

If the broadcast is interrupted, try to reduce the screen resolution of the smartphone to 720p in the developer settings (Settings → About Phone → MIUI version – press 7 times).

Important: on Xiaomi TVs with Google TV (e.g. Mi TV Q2 2026), Google Cast is the priority, and on PatchWall models, Miracast is the priority, which affects compatibility with other brands.

How to stream Xiaomi screen to your computer (Windows/Mac)

If you need to duplicate the screen of Xiaomi smartphone on a laptop or PC, you can do without additional programs - built-in Windows or macOS is enough. However, for stable operation, you will need a Wi-Fi adapter with Miracast support (on PCs older than 2018 it may not be).

For Windows 10/11:

1. Press Win + K and select Connect to the wireless display.
2. On a Xiaomi smartphone, turn on Broadcast (as in the instructions above) and select your PC from the list.
3. Confirm the connection on both devices.

For macOS:

There is no built-in Miracast support on the Mac, but you can use AirPlay (if you have Xiaomi with HyperOS):

1. Install AirServer or Reflector (paid, but there are trial versions) on your Mac.
2. On your smartphone, turn on the Broadcast and select your Mac as an AirPlay receiver.

⚠️ Note: When broadcasting to PC via Miracast, there may be a delay of up to 500 ms, which is normal for this protocol. USB-C → HDMI Supported by DisplayPort Alt Mode.

• 👁️ Data Leak: Screen Mirroring sends all notifications to the TV screen, including messages from instant messengers and banking apps.
• 📡 Public Networks: Never use Cast in public Wi-Fi (cafes, airports) – this is a risk of connecting to other people’s devices.

To minimize the risks:

1. Use guest mode on your Xiaomi TV for temporary connections.
2. Turn off automatic connection to known devices in Cast settings.
3. To broadcast sensitive content (such as working documents), use a wired connection (HDMI or USB-C).

💡

If you are broadcasting a screen on someone else’s TV (for example, in a hotel or at work), after using it, be sure to remove it from the list of trusted devices in the Cast settings on your smartphone.
