Xiaomi’s modern smart TVs, powered by Android TV or PatchWall, offer users unlimited multimedia content. One of the most popular use cases is the ability to display images from a smartphone or tablet to a large screen without using extra wires, allowing them to show photos to friends, watch movies from online cinemas in high resolution, or even play mobile games with improved graphics.
The streaming setup process, often referred to as screencasting or casting, can vary depending on your TV model, software version and type of mobile device used. In some cases, the feature works instantly, in others it requires manual activation of certain data protocols. Understanding the differences between Miracast, DLNA and Chromecast technologies will help you choose the best method for your situation and avoid common connection errors.
In this article, we will take a closer look at all the available ways to set up a broadcast, look at the nuances of working with Android and iOS devices, and pay special attention to diagnosing connection problems. You will learn how to ensure stable video and sound transmission, what router settings can affect the quality of the picture, and how to use third-party applications to expand the functionality of your Xiaomi TV.
Preparation of equipment and network for stable operation
Before you start directly configuring your broadcast functions, you need to make sure that all your equipment is ready to work in a single ecosystem. The fundamental requirement for most wireless media transmission methods is to have all your devices on the same LAN. If your TV is connected to an Ethernet cable and your smartphone uses 4G mobile Internet, you won’t be able to establish a connection.
Owners of dual-band routers should note one critical caveat: Many modern routers broadcast two networks: 2.4 GHz and 5 GHz. Although they come from a single device, this can be a hurdle for some detection protocols (especially older versions of DLNA).
⚠️ Warning: Make sure that both the TV and smartphone are connected to the same thing SSID-If your router divides the ranges into different names (e.g,"Home_2.4" and"Home_5"), Connect both gadgets to the network 5 GHz for better video transfer speeds in 4K, or 2.4 GHz, if signal range is important, but don't mix them.
It’s also worth checking out software updates on the Xiaomi Mi TV or Redmi TV itself. Manufacturers regularly release patches that improve the stability of the Wi-Fi module and compatibility with new versions of mobile operating systems. Old firmware can cause the device to simply not see connection requests from new smartphones.
Use of the built-in Mi Remote function and wireless display
The most versatile way to do this without additional software is to use the native Wireless Display feature, which is based on the Miracast standard, which allows you to broadcast the image one-to-one: everything that happens on your smartphone screen is displayed on your TV, which is ideal for showing presentations, browsers or application interfaces that do not have a built-in Translate button.
To activate this feature on Xiaomi TVs with PatchWall shell or pure Android TV, you need to do the following: First, look for an icon on the list of applications on the home screen called “Wireless Display”, “Miracast” or “Translation” in some models, this feature is already built into the system settings and does not require running a separate application.
When you start, you'll have a wait for the connection on the TV, and now you'll get to the smartphone settings, and the path may vary depending on the phone manufacturer (MIUI shell, HyperOS, OneUI, etc.), but the logic is the same:
- 📱 Open the “Settings” of the smartphone and go to the “Connection and Sharing” or “Screen” section».
- 📡 Find the option “Translation”, “Wireless monitor”, “Smart View” or “Projection».
- 🔍 Wait for the name of your Xiaomi TV to appear in the list of available devices.
- ✅ Click on the TV name to initiate the connection.
Importantly, when using Miracast, the smartphone can get more hot as it encodes a video stream in real time, and in this mode, the phone screen does not go out, which can be inconvenient if you just want to listen to music or an audiobook through the TV.
💡
If the TV doesn’t appear on the list, try temporarily turning off mobile internet (data transfer) on your smartphone, leaving only Wi-Fi. This sometimes helps the system prioritize local device search.
Broadcast via Chromecast built-in for Android and iOS
Most modern Xiaomi TVs are Google certified and have Chromecast technology built in, which is more advanced than Miracast, because it allows you not only to duplicate the screen, but send a link to the TV to content that the TV plays itself, which frees the smartphone for other tasks and saves its battery power.
To work this method on your smartphone should be installed Google Home app (for basic configuration and management) or applications with support for casting, such as YouTube, Netflix, IVi, Okko. The algorithm of actions is extremely simple: you open the video on your phone, click the characteristic icon of the rectangle with Wi-Fi waves in the corner of the player and choose your TV.
However, if you want to stream the contents of the Chrome tab or the screen of apps that do not support casting natively, you can use the screen Translation feature through the Google Home app:
- Launch the Google Home app on your smartphone.
- Find your Xiaomi TV in the list of devices.
- Press the button “Cast my screen”
- Confirm the action on the phone by allowing the capture of the image.
⚠️ Note: When streaming via Chromecast, video quality depends on the speed of your Internet channel, not just the speed of your local Wi-Fi network, as the TV will download content directly from the network.
The advantage of this method is that it supports high resolution 4K HDR and can control playback from your phone as if from a remote control, so you can pause the video, adjust the volume or select other videos while the TV continues to play the movie.
☑️ Checking before launching Chromecast
Features of connecting Apple devices (AirPlay 2)
Owners of Apple (iPhone, iPad) are no less fortunate, as many new models of Xiaomi and Redmi TVs officially support the AirPlay 2 protocol. This allows you to broadcast images, videos and sound from iOS and macOS devices without installing any additional applications on the TV.
To check for support, make sure your TV model is no earlier than 2019 and is certified accordingly.The connection process is as simple as possible: just open the Control Point on your iPhone (swipe down from the upper right corner or bottom up, depending on the model), click on the Screen Replay button (two rectangles) and select your Xiaomi TV.
When you first connect to the TV screen, an access code may appear (PIN-The code that you're going to have to enter on your iPhone is a security measure that prevents unauthorized access to your screen. After a successful pair of devices, the code won't be asked unless you reset your TV settings.
| Parameter | Miracast | Chromecast | AirPlay 2 |
|---|---|---|---|
| Type of device | Android, Windows | Android, iOS, PC | iOS, macOS |
| Dependence on the phone | High (screen active) | Low (phone free) | Low (phone free) |
| Video quality | Depends on the phone. | Up to 4K HDR | Up to 4K HDR |
| Stability | Medium | Tall. | Very high. |
If your Xiaomi TV is older and doesn’t have AirPlay support built in, don’t despair. In the Google Play Store, you can find third-party emulator apps like AirScreen or AirPin that add this functionality artificially.
Broadcasting through DLNA-applications
The DLNA protocol is one of the oldest and most compatible ways to transfer media files, not live streaming, but allowing you to open files (photos, videos, music) stored in your smartphone memory or on a memory card connected to it, ideal for viewing a family archive of photos or movies downloaded in advance.
Xiaomi TVs often already have a DLNA-enabled media player pre-installed (like Gallery or Video) and you just have to run it and choose the Device or Network source. However, for more flexible management, it’s better to use third-party controller apps on your smartphone, such as BubbleUPnP, LocalCast or a standard VLC player.
So the process is, you open a video file in a player on your smartphone, you select the Translate or Cast option, and you see your TV in the device list, and the file starts to buffer and play on the big screen, and the main advantage of DLNA is that you can turn off the screen of your smartphone or even break the connection once you start playing, and the movie will continue to go.
Why can't DLNA see the files?
Note that DLNA does not support all video formats. If the TV cannot decode a specific codec (e.g., some variations of HEVC or AV1), playback may not start even if the file is successfully transmitted.
Resolving and eliminating delays
Despite the technology, users often face problems with setting up the broadcast, the most common being high lag between action on the smartphone and display on the screen, or periodic twitching of the picture, often due to overloading the Wi-Fi channel.
If you're seeing compression artifacts or audio and video desynchronization, try changing the router's settings. The 20 MHz channel width is more stable but slow, whereas 40 MHz or 80 MHz gives speed but is subject to interference. The 5 GHz band is strongly recommended for 4K video broadcasting.
⚠️ Warning: If you stream through Miracast, the sound is coming through the speaker of the phone, not the TV, check your Bluetooth settings. Sometimes the phone automatically connects to wireless headphones or speakers, intercepting the audio stream. Turn off Bluetooth to check.
Another common problem is not being able to find a device, and in this case, rebooting the network equipment down the chain helps: turn off the router, then the TV, then the phone, turn on the router, wait for the full load, then turn on the TV and then the phone. This sequence ensures the correct receipt of IP-Addresses and update routing tables.
💡
The stability of wireless broadcasting is 90% dependent on the quality of the Wi-Fi signal and the absence of interference in the air, not on the power of the TV itself.
In some cases, antivirus software on a smartphone or a built-in router firewall can block the ports needed to detect devices (usually 1900 ports for DLNA and 8008/8009 ports for Chromecast).If nothing helps, try temporarily disabling protection to test the hypothesis.
Using third-party applications to enhance opportunities
Xiaomi TV’s regular functionality can be expanded significantly with apps from the Google Play store. For example, the Web Video Caster app allows you to stream video from almost any site that opens in your phone’s browser, bypassing the limitations of embedded players. It independently extracts the video stream and sends it to the TV.
For gamers who want to play mobile games on a large screen with minimal latency, there are specialized applications that optimize video streaming. They may require the installation of a client part on both a TV and a smartphone, such as ApowerMirror or TeamViewer, although they are more remotely controlled.
Do not forget about the possibility of wired connection via the adapter. USB-C to HDMI. If your smartphone supports video output (technology) MHL, Slimport or just DisplayPort Alt Mode, you can connect it directly to the Slimport. HDMI-This ensures zero latency and maximum picture quality, which is critical for dynamic games or work.
