Modern Xiaomi smartphones have powerful screens and processors that allow you to play content in high resolution, but sometimes a diagonal of 6 inches becomes not enough. You want to bring your favorite video, presentation or game to the big screen of the TV. Fortunately, the ecosystem of MIUI and HyperOS offers many built-in tools to solve this problem without having to buy complex adapters.
The broadcast process, often referred to as casting or mirroring, can be done wirelessly over Wi-Fi or wired through a wired channel. HDMI-The choice of method depends on the model of your TV, the version of the smartphone operating system and the quality of the wireless network. In this article, we will discuss in detail all the available ways so that you can enjoy content on the maximum screen.
It is worth noting that the stability of the connection directly affects the quality of the picture and the absence of delays. Before setting up, make sure that both devices are serviceable and charged. For wireless video transmission in 4K resolution, it is recommended to use a 5 GHz Wi-Fi network. This is a critical nuance that is often ignored, getting jerks and desynchronization of sound at the output.
Wireless broadcasting through the built-in function "Translation"
The easiest and fastest way to display an image is to use a native system function. In the MIUI and HyperOS shells, this tool is called Translation (or Cast in global versions), it is based on the Miracast and DLNA protocols that are supported by most modern Smart TVs. You do not need to install third-party apps if the TV is on the same network.
To activate the function, open the notification curtain and find the Translation icon. If it is not on the visible panel, click on the edit button (usually a three-dot icon or a pencil) and drag the desired widget into the active zone. Once turned on, the smartphone will begin to search for available devices on the local network.
If the TV isn't listed, check the Smart TV settings. Many Samsung, LG or Sony models need to manually allow mobile connection, either through the network menu or under the "Connect with Mobile Device" section, without which the TV will ignore smartphone requests.
Once you select your TV, you'll see a confirmation request on your smartphone screen, and some TV models may see a window with the code you want to enter on your phone, or simply a request for "Allow Connection," and once confirmed, the screen of your smartphone will be fully copied to the TV.
⚠️ Note: When using the Translation feature, the smartphone screen must be turned on. If the phone locks or goes into sleep mode, the image transfer will stop and the TV will go into standby mode.
💡
To save battery power during a long broadcast, reduce the brightness of the smartphone screen, as it does not affect the brightness of the image on the TV.
Using Google Chromecast built-in technology
Many modern TVs have built-in support for Google Chromecast technology. Unlike full screen mirroring, this method allows you to stream content directly from apps like YouTube, Netflix or Google Photos. This is a more energy-efficient way, since the phone acts only as a remote control, and the video is downloaded by the TV directly from the Internet.
To start the broadcast, open the supported app on your Xiaomi smartphone. In the corner of the video player or in the app menu, find the characteristic rectangle icon with Wi-Fi waves in the corner. Click on it and select your TV from the proposed list of devices.
The advantage of this method is that you can fold the app or even lock the phone, and the playback on the TV will not be interrupted. Also, the video quality is often higher, since it is not compressed to transmit over the air, but streamed in its original quality.
If the Chromecast icon doesn’t appear, make sure:
- 📱 Smartphone and TV connected to the same Wi-Fi network.
- 📺 Chromecast service is enabled on the TV (usually enabled by default).
- 🌐 Both devices have internet access for an initial handshake.
Broadcasting through TV manufacturers' applications
TV makers often develop their own apps to improve compatibility with smartphones. For Xiaomi owners, this can be an even more stable solution than the standard Miracast, especially if there are connection problems.
Popular solutions include LG TV Plus for LG TVs, SmartThings for Samsung and Video & TV Cast for universal use.The setup process is usually standard: download the app from Google Play, connect to the same Wi-Fi network and follow on-screen instructions.
Some apps allow you to broadcast not only the picture, but also the sound separately, or use the phone as a touchpad to control the cursor on the TV screen, which is especially convenient when working with web pages or office documents on a large screen.
Below is a table of compatibility of popular apps with TV brands:
| Brand TV | Official annex | Miracast support | Support for AirPlay 2 |
|---|---|---|---|
| Samsung | SmartThings | Yes. | Yes (new models) |
| LG | LG TV Plus | Yes. | Yes. |
| Sony | Video & TV SideView | Yes. | Yes. |
| TCL / Xiaomi TV | Google Home / Mi Remote | Yes. | No. |
What to do if the app can’t see the TV?
Connecting via HDMI adapter
When wireless connectivity is unstable or requires maximum image quality without compression, wired connectivity comes to the rescue. For Xiaomi smartphones with USB Type-C port, there are special adapters that support the MHL or DisplayPort Alt Mode standard, which allows you to turn the phone into a full-fledged media center.
It is important to understand that not all Xiaomi models support video output via USB. Flagship series such as Xiaomi 13, Xiaomi 14, Mi 10 and some Mi Mix series models are equipped with USB 3.0/3.1 ports with video output support. Budget models (Redmi Note series, POCO M) often have only USB 2.0, which does not transmit video.
You'll need a USB-C to HDMI adapter to connect to your smartphone, and you'll need an HDMI cable to connect to your TV, and then you'll need to select the appropriate signal source (e.g. HDMI 1) on your TV, and the image will automatically appear.
The advantages of the wired method are obvious:
- 🎮 No delay (input lag), which is critical for mobile games.
- 🔋 The phone can be charged while running (if the adapter has a charging port).
- 📉 Stable picture without compression and interruption artifacts.
☑️ Checking before buying an adapter
Configure via Mi Remote and IR port
While it’s not a live screen, controlling the TV through the IR port of a Xiaomi smartphone is an important part of the ecosystem. Many Xiaomi models feature an integrated IR transmitter. The Mi Remote app (or “Remote”) lets you control the TV, turning the phone into a universal remote.
This is useful if you want to start a Smart TV, switch the signal source to an HDMI where the adapter is connected, or simply add volume while you stream content in another way.
To set up, open the app, press +, select the TV device type and brand. Follow the on-screen instructions by pressing the buttons that appear on the display until the TV responds. Once you save the profile, the remote will always be at hand.
If you don't have an IR port on your smartphone, you can use Wi-Fi control for smart TVs, and the principle is the same, but both devices need to be on the same network, so you can not only switch channels, but also type text from the phone's keyboard, which is much more convenient.
⚠️ Attention: IR remote only works in line of sight. Make sure there are no obstacles between the top end of the smartphone and the TV receiver.
Solution: Delays, black screen and out-of-synchron
When broadcasting wirelessly, users often face technical problems, the most common being the desynchronization of sound and video ( lipsync), which can be ahead of the image or behind by a few seconds, usually due to overloading of the Wi-Fi channel or insufficient power of the TV processor when decoding the stream.
Another problem is the black screen when running video. Some applications (e.g. Netflix, Disney+) use HDCP content protection. If your HDMI adapter or broadcast method doesn't support this standard of protection, you'll see a black image, although the sound will go, in which case only using official apps on a Smart TV or a wired connection with a certified cable helps.
To minimize delays, try the following:
- 📶 Connect the TV to the router via cable LAN, If the Wi-Fi signal is weak.
- 📱 Close background apps on your smartphone that consume the Internet.
- 🔄 Restart the router to clear the cache and select a less loaded channel.
💡
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 just the power of the smartphone.
