Xiaomi’s modern smartphones have powerful multimedia capabilities that allow you to stream content to the big screen without losing quality. Users often wonder how to display an image from a mobile device to a TV to enjoy movies, photos or games with friends. The synchronization process may seem difficult only at first glance, but in fact it takes only a few minutes with the right approach.
There are many ways to (implement) a connection, from Miracast and DLNA wireless protocols to physical connection via HDMI cable. The choice of a particular method depends on the model of your TV and the version of the MIUI or HyperOS operating system. In this article, we will discuss all the current options in detail so that you can choose the most suitable for your situation.
Before you start setting up, make sure that both devices are running correctly and have up-to-date software updates, which will help avoid most common compatibility errors and ensure a stable video stream.
Wireless connection via built-in broadcast function
The easiest and most popular way to do this is to use a built-in MIUI shell tool called Translation (or Cast in global versions), which is based on Miracast technology, which allows you to duplicate your smartphone screen on your TV without having to install additional software.
To activate the mode, lower the notification curtain and find the "Translation" icon. If it is not on the first screen, click on the edit button (usually a square with a pencil or three dots) and drag the icon to the active area. Once turned on, the system will automatically search for available devices on the local network.
You may also need to run an app on your TV screen to receive the signal, and depending on your TV brand, it can be called by different names:
- 📺 Samsung's Screen Mirroring or Smart View feature
- 📺 LG — Screen Share appendix
- 📺 Sony – Screen Duplication Mode or Miracast
- 📺 Philips – Miracast option on the network menu
⚠️ Note: If the TV doesn't appear on the list, try rebooting the router.Dual-band routers sometimes isolate devices if the phone is connected to 5GHz and the TV is to 2.4GHz, although modern routers usually combine them into a single network.
Once you select your TV from the list on your Xiaomi smartphone, you will see a request for confirmation of connection on your TV screen. Use the remote to agree, and the image from the phone will instantly appear on the big screen. Latency in this mode is minimal, allowing you to comfortably view photo galleries or presentations.
Using the DLNA protocol for multimedia
If your goal is not to duplicate the screen, but to play a specific video file, music or photo shoot, then the technology is the same. DLNA Unlike Miracast, it doesn't load the processor with a constant encoding of the video stream, but just transfers the file to the decoder of the TV. 4K-film.
In Xiaomi smartphones, the standard video player already has built-in DLNA support. Open the video file, click on the icon "TV" or "Cast" in the corner of the player screen. The system will suggest choosing a playback device. The TV should support DLNA Renderer technology, which is found in 99% of modern Smart TVs.
The advantage of this method is that it's autonomous: once you start playing, you can roll up the player, go online, or even lock the screen, and the video on the TV will continue to go, but the control of rewinding or volume in this mode is often limited.
For more advanced users, there are third-party applications such as BubbleUPnP or Xiaomi Video (in the global version) that are able to find media files not only in the phone’s memory, but also on NAS network storage, streaming them directly to TV.
💡
When using DLNA for heavy movies (over 20 GB), make sure your router supports 802.11ac (Wi-Fi 5) or later, otherwise image slowdowns are possible.
Broadcasting through the Google Home app
Owners of TVs with Android TV or Chromecast can use the official Google Home app, which often works more consistently than Xiaomi’s standard Translation, especially if protocol compatibility issues arise.
You first need to download the Google Home app from the Play Market and log in to your Google account. Once opened, the program will automatically scan the network and find all compatible devices, including smart speakers, lamps and, of course, a TV.
The algorithm of actions is very simple:
- Launch the Google Home app on your smartphone.
- Find your TV card in the list of devices.
- Press the button “Cast screen” (Cast screen).
- Confirm the action by pressing “Translate screen” in the pop-up window.
This is particularly useful because it allows you to stream content from individual apps (like YouTube or Netflix) without loading your phone's processor, so you click the broadcast icon inside the source app itself, select the TV, and the phone becomes a remote control.
| Method | Delay. | Quality. | Battery consumption |
|---|---|---|---|
| Miracast (Translation) | Low. | High (depends on Wi-Fi) | High-pitched |
| DLNA | Absent. | Maximum (original) | Low. |
| Google Home | Medium | High. | Medium. |
| HDMI Cable | Absent. | No loss. | Charging the phone |
Physical connection via HDMI adapter
For those who require maximum image quality and no delays (such as gaming), wireless methods may not work, in which case a wired connection saves. However, since modern Xiaomi does not have a mini-HDMI port, a special USB-C to HDMI adapter will be required.
It is important to understand that not all Xiaomi smartphones support video output via the charging port. Video output function (Video Out) is usually only present in the flagship models of the Mi series, Xiaomi 11/12/13/14 and some models of the Black Shark series. Budget models Redmi and Poco often lack this hardware capability, and the adapter will not work.
The connection process is elemental: insert the narrow end of the adapter into the USB-C connector of the smartphone, and at the other end insert the HDMI cable that goes to the TV. Switch the signal source to the TV to the appropriate port (for example, HDMI 1).
⚠️ Note: When using an adapter, the phone can heat up quickly, as the video chip is active.

Setting up image and sound parameters
After successful connection, it is often necessary to fine tune the screen resolution of the smartphone (for example, 2400×1080) may not coincide with the resolution of the TV (1920×1080 or 3840×2160). In most cases, the system adjusts automatically, but sometimes the picture may be cropped or have black stripes.
To change settings, go to Settings → Connection and Sharing → Broadcast. In the settings menu (cogs), you can try changing the resolution or disabling the option “Hide black edges” if the image looks incorrect. Also available is the “Private Mode” feature, which hides notifications from messengers during the broadcast.
Sound is also a must-have. Audio is also transmitted to the TV by default. If you want to leave sound on your phone (for example, to listen to headphone comments while others are watching video), there is often an audio output switch in the Quick Settings menu. However, in Miracast, audio and video are not technically possible at the protocol level.
☑️ Diagnosing Connection Problems
Solving Connection Problems and Errors
Despite the simplicity of the technology, users often face difficulties. The most common problem is that the TV simply cannot see the phone. 80% of the time, this is solved by checking the Wi-Fi range. Make sure that both devices are connected to the same frequency (preferably 5 GHz for speed or 2.4 GHz for compatibility with old TVs).
The second common mistake is to desynchronize audio and video, which occurs when there is a weak Wi-Fi signal, try to get closer to the router or reduce the quality of the video you are streaming in the app settings, and close the background apps on your smartphone that may consume traffic also helps.
If the connection is broken immediately after the start:
- 🔄 Restart both devices (total shutdown and on).
- 📶 Forget the Wi-Fi network on your phone and connect again.
- 🛡️ Check for antivirus or firewall that can block local connections.
In some cases, the problem is with the TV's outdated firmware, go to the Smart TV settings and check for system updates. Manufacturers often release patches that improve compatibility with newer versions of Android and MIUI.
💡
The stability of a wireless connection is 90% dependent on the quality of the Wi-Fi router signal and the absence of physical obstacles between it and the devices.
