How screen broadcasting works on Xiaomi devices: a complete guide

Broadcasting screens from Xiaomi devices to a TV or other display has become an integral part of the modern multimedia experience. Whether watching movies, presenting photos or streaming games, the ability to wirelessly duplicate the screen saves time and makes it easier to interact with content. However, many users have difficulty configuring this feature: the connection is interrupted, the picture slows down, the devices simply “don’t see” each other.

In this article, we will discuss how screen broadcasting works on Xiaomi, from Redmi and POCO smartphones to Mi TV and Xiaomi TVs. You will learn about supported standards (Miracast, AirPlay, Wi-Fi Direct), model restrictions, and get step-by-step instructions for different scenarios.

1. Screen broadcasting technologies in Xiaomi ecosystem

Xiaomi devices support several wireless image transfer protocols, and the choice of technology depends on the model of the gadget, the operating system and the target device (TV, projector, monitor).

• 📶 Miracast is a universal protocol that works via Wi-Fi Direct. supported by most Xiaomi smartphones (starting with the use of the most popular Wi-Fi Direct). MIUI 8) and Mi TVs TV. Does not require connection to the router, but is sensitive to interference.
• 🍎 AirPlay is Apple’s technology, but Xiaomi has added support for it to some TV models (e.g. Mi). TV Q1E It allows you to broadcast the screen from your iPhone or Mac.
• 🔄 Wi-Fi Direct, an alternative to Miracast, is often used to connect to projectors or older TVs. requires manual tuning on both devices.
• 📱 Google Cast (Chromecast) – supported by Xiaomi TVs with Android TV (Like Mi. TV Stick. It works through apps like YouTube or Netflix.

It's important to understand that not all technologies are compatible, for example, the Redmi Note 10 won't be able to stream a screen to a Samsung TV via AirPlay, but it will connect to Miracast without any problems, while the Mi TV A2 supports both Miracast and AirPlay, making it more versatile.

Also, consider the limitations of MIUI. For example, in older firmware (MIUI 9 and below), the Wireless Display function may not work as well. Upgrading to MIUI 12+ usually solves most problems.

2. Supported Devices: What Does Xiaomi Know?

Before you try to set up a livestream, check if your device supports this feature. Below is the compatibility table for popular Xiaomi models:

An important nuance: Xiaomi Android TVs (such as Mi TV Stick or Mi Box S) support Google Cast, but not always Miracast as a receiver, which means you can stream content from apps (YouTube, Netflix) on them, but not the entire screen of your smartphone.

If your model is not in the table, check the protocols in the settings:

• On a smartphone: Settings → Connections and Sharing → Wireless display.
• On TV: Settings → Network and Access → Wireless projection or Screen Mirroring.

💡

If the settings of the TV do not include "Wireless projection", update the firmware through Settings → About TV → Software Update. Often the manufacturer adds support for new protocols in the latest versions.

3. Step-by-step setting of the broadcast from smartphone to Xiaomi TV

Consider the most common scenario: streaming a Xiaomi/Redmi/POCO smartphone screen to a Mi TV or Xiaomi TV using Miracast protocol, both devices must be connected to the same Wi-Fi network (or use Wi-Fi Direct).

Make sure your TV and smartphone are connected to the same Wi-Fi network (2.4GHz recommended)

Update the firmware on both devices

Turn off VPN and energy saving modes

Close background applications on your smartphone-->

Instructions for the smartphone:

1. Open Settings → Connections and Sharing → Wireless Display (or Cast in newer versions of MIUI).
2. Turn on the function and wait until the smartphone finds available devices.
3. Select your TV from the list. If it's not available, click Update or check your TV settings.
4. Confirm the connection on both devices (entry may be required) PIN-code).

Instructions for television:

1. Go to Settings → Network and Access → Wireless projection (or Screen Mirroring).
2. Activate the reception mode (sometimes called Miracast or Wireless Display).
3. If the TV is not detected, try restarting it or changing the Wi-Fi channel in the router settings.

Once successfully connected, the smartphone screen will be duplicated on the TV, and the image latency is usually 50-150 ms, which is noticeable in games, but not critical for video.

4. Stream from iPhone to Xiaomi TV (AirPlay)

If you have a Xiaomi TV with AirPlay support (such as Mi TV Q1E or Xiaomi TV Q2 2023), you can stream the screen from an iPhone or iPad. This feature is useful for owners of Apple equipment, but has limitations:

• 📱 Only Android TVs are supported TV 10+ firmware not older than 2022.
• 🔒 Not all apps allow live streaming via AirPlay (for example, Netflix can block external screen output).
• 🎮 The delay in broadcasting games can reach 200 ms, which makes it unsuitable for shooters.

How to connect:

1. On TV: Settings → Network and Access → AirPlay → turn on the feature and remember the name of the device.
2. On iPhone: swipe up to call Control Point → press Screen Duplicate → select your Xiaomi TV.
3. The first connection may require you to enter a code that will appear on the TV screen.

If the broadcast is interrupted, check:

• Distance between devices (no more than 10 meters).
• No interference from other Wi-Fi networks (use a 5GHz channel for stability).
• Software updates on the TV (in older versions AirPlay could work incorrectly).

💡

AirPlay on Xiaomi TV supports not only screen duplication, but also music streaming (via Control Point → Playback Control on iPhone).

5. Common Problems and Their Solutions

Even when you set it up properly, users often encounter errors, and let's look at typical scenarios and how to fix them.

⚠️ Warning: If Miracast connects to a picture that slows or crumbles into squares, the problem may be the video codec. Xiaomi TVs older than 2020 do not support encoding H.265 (HEVC) For wireless broadcasting, try to turn on Performance mode in the wireless display settings on your smartphone.

Problem 1: The TV is not detected.

• 🔌 Check that both devices are connected to the same Wi-Fi network (not the guest one!).
• 🔄 Restart your router – sometimes DHCP-The server does not provide the correct IP-multicast addresses.
• 📱 On your smartphone, turn off Adaptive Brightness and Power Saving Mode – they can interfere with a stable connection.

Problem 2: Sound is broadcasted, but no images

• 🔊 Check if the TV is on sound only (sometimes activated accidentally).
• 📺 Switch the signal source on your TV to Screen Mirroring or Miracast.
• 🛠️ Update the TV firmware – in older versions there could be bugs with video decoding.

Problem 3: Large delay (lag) during broadcasting

• 📶 Switch to 5GHz network – it is less loaded and provides less latency.
• 🎮 If you play, reduce the broadcast resolution in the wireless display settings (for example, to 720p).
• 🚫 Disable other devices connected to the router – they can cause interference.

If none of these methods worked, try alternative streaming methods (e.g., through Google Cast for video or DLNA for photo).

6. Alternative methods of broadcasting

If standard methods don't work, you can use third-party solutions that require additional devices or programs, but often provide a more stable connection.

• 📦 Adapters Miracast/Wi-Fi Display (e.g. Xiaomi Mi) TV Stick or AnyCast. Connect. HDMI-They're ported to the TV and convert the signal, suitable for old TVs without Smart. TV.
• 💻 Wired connection through USB-C/HDMI. For Xiaomi smartphones with DisplayPort Alt Mode support (e.g. Xiaomi) 12 Pro or Redmi K50). Adapter required USB-C → HDMI.
• 🌐 Streaming apps (e.g. ApowerMirror or TeamViewer QuickSupport) run over a local network but can add additional lag.

Example of settings via USB-C → HDMI:

1. Buy a certified adapter (e.g. Baseus USB-C to HDMI).
2. Connect the adapter to the smartphone, and HDMI-cable.
3. On your smartphone, select Image Transfer mode (can appear automatically).
4. On the TV, select the appropriate HDMI-entrance.

The advantage of wired connection is zero latency and support for resolutions up to 4K@60Hz. The disadvantage is the limited length of the cable and the need for an adapter.

💡

Wireless technology (even Wi-Fi 6) does not provide a stable 60 FPS without artifacts.

7. Optimization of broadcasting for games and video

If you plan to stream games or videos in high resolution, standard settings may not work. Here's how to improve quality and reduce latency:

• 🎮 For games: Use 5GHz network and place router closer to devices. In the wireless display settings, select Performance Mode (if available). Close all background apps on your smartphone, especially instant messengers and social networks.
• 🎬 For video: If you're streaming a movie, use Google Cast through apps (YouTube, Kodi) - this will reduce the load on the smartphone's processor. HDR In video settings – some Xiaomi TVs incorrectly process it when broadcasting wirelessly.

You can use the Display Lag Tester app (available on Google Play) to test the delay. Normal values for Miracast are:

• 30-50 ms is excellent (suitable for most games).
• 50–100 ms – acceptable (notably in dynamic scenes)
• 100+ms is not comfortable for games, but it is normal for video.

If latency is critical (for example, for shooters), consider buying custom adapters like Razer Kishi with USB-C → HDMI support.

8.Security and confidentiality during broadcasting

Wireless screen broadcasting can pose privacy risks, especially if you connect to public networks (such as a cafe or hotel).

• 🔒 Use the home network. Public Wi-Fi is easy to intercept traffic. Miracast/Wi-Fi Direct.
• 🛡️ Turn off the broadcast after use. Some TVs keep the connection in the background.
• 👁️ Check the connected devices. In the settings of the TV (Settings) → Wireless projection → Connection history: You can see a list of devices that previously connected to your display.

⚠️ Attention: In the firmware MIUI Before version 12.5, there was a vulnerability that allowed you to connect to your smartphone through Miracast without confirmation!

If you need to broadcast sensitive information (such as documents or correspondence), it is better to use a wired connection or specialized applications with encryption (for example, TeamViewer with enabled communication). E2E-encryption).

For additional protection, you can turn on Filtration MAC-Addresses on the router, allowing only trusted devices to connect, and this will prevent unauthorized access to your network during the broadcast.
