Xiaomi’s modern smartphones have evolved into powerful multimedia centers that can not only play content locally, but also broadcast it to large screens. The display of images on the TV allows you to enjoy movies, photos and games with maximum comfort using a diagonal of 40, 55 or even 65 inches. This is especially true when you want to show friends pictures taken or launch videos from an online cinema that does not have a native app on your TV.
There are several ways to broadcast the screen, each with its own features and hardware requirements: some work at the level of the MIUI or HyperOS operating system, others require the installation of third-party software, and others depend on the capabilities of the TV itself. It is important to understand the difference between simple mirroring and content streaming (Casting) to choose the best option for your situation.
In this article, we will take a look at all the ways Xiaomi can connect to your TV, from built-in features to specialized applications, how to set up a Wi-Fi connection, what to do if devices can’t see each other, and how to ensure stable signal transmission without delay.
Preparation of equipment and network
Before you start setting up, you need to make sure your hardware is ready to go. The fundamental requirement for wireless data is to have a common LAN. The smartphone and TV must be connected to the same router, otherwise they will not be able to detect each other.
Note the frequency of Wi-Fi connections. For high-resolution video, especially in 4K, it is preferable to use the 5GHz band. It provides higher bandwidth and less interference compared to the 2.4GHz standard.
- 📡 Make sure the router is turned on and dispensing IP-addresses to both devices.
- 📱 Check that the Xiaomi smartphone is enabled Wi-Fi and Bluetooth.
- 📺 The TV should support Smart Technology TV or be connected to a TV set-top box.
If you use a wired connection via a USB-C to HDMI adapter, the network requirements are eliminated, in which case the smartphone transmits the video directly through the cable, which guarantees no delays, but limits the mobility of the device.
Use of the built-in "Translation" function
The MIUI shell and the new HyperOS already have a system-based image output tool pre-installed, which is based on the Miracast protocol and does not require any additional software installation, ideal for fast mirroring of the desktop or settings menu.
To activate the function, lower the notification curtain and find the Translation icon. If it's not on the visible panel, click on the edit button (usually three dots or a pencil icon) and drag the icon to the active area.
☑️ Pre-broadcast checks
You might have a request on your TV to confirm your connection, and you'd have to take the remote control and agree to the session, and from that point on, everything that happens on your smartphone screen will be duplicated on a large display.
⚠️ Note: When using the built-in broadcast, the smartphone screen should be turned on. If the phone screen goes out, the broadcast is also interrupted, since this is a mirror display, not streaming.
Broadcasting via Google Home and Chromecast
Most of today's TVs and media consoles support Google Cast, a more advanced protocol that allows you to stream content directly from apps without loading your smartphone processor, and Google Home is used to manage this process.
First, you need to download and install the app from the Google Play store. Once launched, the program will automatically scan the network and find available Chromecast devices or TVs with built-in Android TV.
In the application interface, click on the "Translate screen" or "Translate audio / video" button. The system will prompt you to select a source. If you want to show the contents of the browser or game, select the "Translate screen" option.
- 🎥 Supports high quality audio and video transmission.
- 📱 The smartphone can be used as a control panel (volume, pause).
- 🌐 Miracast works more consistently on devices with Google ecosystem.
It is important to note that to work through Google Home, the TV must be installed appropriate services, and older models of Smart TV may require a firmware update or use an external console.
Why is Google Home streaming better?
Smart TV apps: Mi TV and third-party solutions
Xiaomi has developed its own Mi TV app (formerly known as Mi Remote or part of the Mi Home ecosystem) that allows not only control of the TV but also broadcast media files.
One of the most popular third-party applications is Web Video Caster or TV Cast, which can pull video streams from the browser and send them directly to the TV, bypassing buffering on the phone, and is especially useful for viewing videos from sites that do not have official apps.
The installation process is simple: download the app to a Xiaomi smartphone and then install the companion app on your TV if required (often available from the Samsung, LG or Android TV app store). After pairing over Wi-Fi, you can select files in the gallery or video in the browser and send them to the big screen.
| Annex | Type of broadcast | Do I need a TV client? | Best for you. |
|---|---|---|---|
| Mi TV Cast | Media files | Yes (on some TV) | Photo and video from the gallery |
| Google Home | Screen + Media | No (built into Android TV) | Universal use |
| Web Video Caster | Streaming video | Yes (or through DLNA) | Online cinemas in the browser |
| Built-in "Translation" | Screen mirror | No (Miracast needed) | Demonstration of menus and games |
Connecting through an adapter
If the wireless connection is unstable or requires maximum image quality without compression, it is worth considering the wired option. For Xiaomi smartphones with a USB Type-C port, there are special adapters for HDMI.
It is important to understand that not all models support video output via USB. DisplayPort Alt Mode is usually available in flagship series (for example, Xiaomi 13, 14, 15 or Mix series). In budget models, the port can be limited to the USB 2.0 standard, which will not allow you to transfer video.
To connect you will need:
- 🔌 adapter USB-C to HDMI video-enabled.
- 📺 Cable HDMI (It usually comes with an adapter or TV).
- 🔋 External power (it is desirable to connect the charging to the adapter).
Once the devices are connected, the TV will automatically determine the new signal source, and you will only have to select the appropriate input (HDMI 1, HDMI 2, etc.) from the signal source menu on the remote control.
⚠️ Note: When using cheap adapters without additional power, the image may blink or disappear.
💡
If you frequently connect your phone to your TV via cable, buy a quality fast charging (PD) adapter to keep your smartphone charging while watching a movie.
Solving Connection Problems
Even when set up correctly, there can be technical failures. Often users are faced with a situation where the TV simply does not see the smartphone in the list of available devices. First of all, check the settings of the firewall on the router - sometimes it blocks local interaction between devices.
Another common problem is desynchronizing audio and video, which is common when using Miracast on congested networks, so try lowering the broadcast quality in your application settings or restarting your router.
If there is an image but no audio, check the audio output settings in the broadcast app itself or in the Android sound system settings. Sometimes the sound continues to go through the phone's speaker until you manually switch it to a Bluetooth or Cast output device.
💡
90% of connection problems are solved by restarting the router and reconnecting both devices to the Wi-Fi network.
In rare cases, you may need to reset your network settings on your smartphone. Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth.This action will delete saved passwords, but can correct network drivers errors.
