Xiaomi’s modern Smart TVs offer incredible multimedia capabilities, allowing you to turn a regular video viewing into a full-fledged theater. However, many users face difficulties when trying to bring an image from a smartphone or tablet to the big screen. This can be necessary to show presentations, watch photos from a vacation with the whole family or run games from a mobile device. Understanding how to broadcast a Xiaomi TV opens up access to the advanced functionality of your media system.
The process of synchronizing devices is not always intuitive, as it depends on the version of the operating system, the model of the TV and the application used. In this article, we will discuss in detail all the current methods of connection, from built-in Android functions to third-party utilities. You will learn how to configure wireless connection, eliminate delays and use the DLNA protocol to transfer heavy files without loss of quality.
Before you start setting up, make sure your devices are ready to go. A few basic conditions must be met to successfully implement wireless data, ignoring which will lead to connection errors. The stability of the Wi-Fi network is a key factor: if the router is overloaded or the signal is weak, the picture will be interrupted.
The first thing to check is that the gadgets are on the same local network. Often users connect the phone to 4G mobile Internet and the TV to home Wi-Fi, which simply “does not see” each other. It is also worth updating the TV firmware through the Settings menu → About TV → System Update, since older versions of MIUI for TV can have bugs in the wireless display module.
Using the built-in “Translation” function in Android
The easiest and fastest way to do this without additional software is to use the native Android operating system feature, which is called Translation, Wireless Monitor or Smart View (depending on the brand of the phone). Xiaomi Mi TV and Redmi TV support Miracast standard, which allows you to duplicate the screen in real time.
To start the process, open the Quick Settings Panel on your smartphone by swiping from top to bottom. Find an icon called Translation or Projection. If there is no icon, click on a pencil or three dots to edit the panel and drag the desired widget into the active area. Once activated, the phone will start searching for available devices within the network range.
When your TV name appears on the screen (like the Living Room MiTV), click on it. The TV screen may have a request to confirm your connection — use the remote to select "Allow" or "Accept," and then the image from the phone is fully copied to the big screen.
- 📱 Make sure that both devices have Bluetooth enabled for an initial handshake.
- 📶 Check that the Wi-Fi router frequency is 5 GHz to minimize delays.
- 🔄 Restart your router if the list of devices is not displayed within 30 seconds.
- 📺 Turn it off. VPN on a smartphone, as it can block local detection.
⚠️ Note: When using the screen duplication function, the smartphone can quickly discharge and the body itself can heat up. This is the normal reaction of the processor to encoding a video stream in real time.
Broadcasting through the Google Home app
If the standard Translation feature doesn’t work or your TV is powered by Android TV, the perfect solution is the official Google Home app, a versatile smart home management tool that also takes over content casting functions.
Download and install the Google Home app from the Play Market. After installation, launch it and log in to your Google account. The app automatically scans the network and finds connected devices. From the device list, select your Xiaomi TV. From the control menu that opens, click the "Cast my screen" button.
Unlike Miracast, Chromecast technology works differently: the phone doesn't send a video stream, it just tells the TV what to play and where to play, which reduces the load on the smartphone and saves battery power. However, it requires a stable Internet connection to work, since content is often downloaded directly from the cloud.
☑️ Preparation for broadcasting through Google Home
Importantly, picture quality is directly affected by Internet speed. If you stream video in 4K and the channel is narrow, the system will automatically lower the resolution to HD to avoid buffering. You can adjust the broadcast quality and resolution from the app menu by selecting Settings → Broadcast quality.
Use of receiver applications (AirScreen and analogues)
In situations where standard protocols are not supported or are not working properly (for example, when trying to connect an iPhone to an Android TV), third-party reciprocating applications come to the rescue.
To get started, find the AirScreen app in the Google Play Store on your Xiaomi TV. Install it and launch it. On the start screen, it will suggest enabling the necessary services — confirm the action. QR-code and name of the device ready to connect.
Now, take your smartphone. If you have an iPhone, just open Control Point and select Screen Replay by looking for the name listed in the TV app. For Android smartphones, the procedure is similar to using embedded broadcast. The AirScreen app provides a more stable connection and lower input latency, which is critical for gaming.
- 🍏 AirPlay protocol support allows easy connection of Apple devices.
- 🛡️ In the paid version, advertising is turned off and support appears HDR.
- ⚙️ Ability to fine-tune resolution and bitrate of video stream.
- 📡 It works even if the TV doesn’t have a Chromecast built-in.
⚠️ Warning: The free version of AirScreen can display banner ads in the corner of the screen during broadcast.For regular use without interruptions, consider purchasing a license.
Why can’t the AirScreen app run?
Transfer of photos and videos over a local area network (DLNA)
When the task is not to duplicate the screen, but to play a specific video file or slideshow photos, the most convenient way to use DLNA technology. This method allows the TV to directly (read) files from the memory of a smartphone or computer, using the Wi-Fi router as a transport highway.
To do this, you'll need a media server on your phone. As a client, Xiaomi TVs usually already have a built-in player or MediaPlayer app installed. You can use DLNA-enabled file managers, such as ES Explorer or specialized applications like BubbleUPnP.
Run a server app on your phone and allow access to your media folders. Open the Media section on your TV or launch a USB/Net video app. Your smartphone should appear on the list of available devices. Going to its folder structure, you can play video directly on your TV using your phone as a remote control.
| Protocol | Type of transmission | Phone load | Support for iOS |
|---|---|---|---|
| Miracast | Screen duplication | Tall. | No (indirectly) |
| Chromecast | Command/Flow | Low. | Yes (via annexes) |
| AirPlay | Flowing | Medium | Yes (indirectly) |
| DLNA | Local access | Minimum | Yeah (via software) |
The main advantage of DLNA is that you can roll the app on your phone, answer a call, or even turn off your smartphone screen — playback on your TV won’t be interrupted.This makes the method ideal for watching long movies or listening to music.
💡
For maximum speed transfer of large files over DLNA, use a router that supports 802.11ac (Wi-Fi 5) or later. Older routers may not be able to handle 4K streams.
Wired connection via HDMI and adapters
Wireless technology is convenient, but it doesn’t always guarantee a perfect picture without delay. If you want maximum stability, for example, for games or professional presentations, a wired connection will be the best choice. Xiaomi TVs are equipped with HDMI ports that receive digital signal without compression.
To connect a modern smartphone, you will need an adapter. For devices with a USB Type-C port, use a USB-C to HDMI adapter. It is important that your smartphone supports MHL or DisplayPort Alt Mode technology, otherwise video transmission over cable will not be possible. iPhone will require a Lightning to HDMI adapter (or USB-C for new models).
Connect the adapter to the phone and then connect it. HDMI-switch the signal source to the TV to the appropriate port (e.g, HDMI 1 HDMI 2) The image will appear instantly, without the need to set up a network or enter passwords.
- 🔌 Use quality cables HDMI version 2.0 or higher to support 4K.
- 🔋 Some adapters require additional power through USB.
- 📺 Don’t forget to switch the signal source to the desired one. HDMI-port.
- 🎮 Ideal for gaming due to lack of input-lag (input delays).
⚠️ Note: When using cheap Chinese adapters without a brand, you may have problems with resolution or sound.
Solution: Why there is no image or sound
Despite the ease of setting up, users often face technical problems, one of the most common is “device found but not connected.” 90% of the time, this is due to router settings, namely, isolation of AP clients. If this feature is enabled, devices on the Wi-Fi network cannot communicate with each other.
Another common problem is desynchronization of sound and video, which happens when the TV's processing power is not enough to decode the stream in real time, the solution is to reduce the broadcast quality in the application settings or switch to a wired connection, and rebooting the router also helps.
If there is no audio at all, check the audio output settings in the app itself (e.g. YouTube or Netflix). Sometimes the system defaults to the phone speaker over the TV. Click on the speaker icon in the player and select the Chromecast or Xiaomi TV output device.
💡
Most connectivity problems are solved by simply restarting the router and checking that both devices are on the same subnet (the same is true). IP-lock-house).
In conclusion, the choice of broadcast method depends on your specific tasks: Miracast is suitable for fast display of photos, Chromecast or DLNA is suitable for watching movies, and HDMI cable is for games. Xiaomi ecosystem is flexible and allows you to combine these methods to achieve the best result.
