Modern Xiaomi smartphones have powerful screens, but to watch movies or games in the company it is much more pleasant to use a large TV display. Connect the device to the home theater in several ways, and the choice of method depends on the model of your TV and the availability of certain ports. Owners of Redmi and Poco equipment often face the question of how to display the image without delay and loss of quality.
There are wired solutions that provide maximum stability, and wireless technologies that allow you to manage content remotely. Wireless streaming has become the standard thanks to the built-in features of the MIUI and HyperOS system that do not require complex router configuration. However, for gamers or those who want to broadcast a screen in 4K, a cable option may be required.
In this guide, we'll take a look at all the current synchronization techniques, from simple built-in tools to the use of specialized adapters. You'll learn how to adjust sound, avoid out-of-synchronization, and what nuances different versions of firmware have. Competent setting will turn your smartphone into a multimedia center control panel.
Wireless connection via built-in translator
The most popular and convenient way is to use Miracast technology or Google Cast protocol. In Xiaomi smartphones, this feature is built deep into the system and does not require installing third-party applications. To get started, make sure your TV supports Smart TV or has a built-in Wi-Fi Direct module.
The setup process takes only a couple of minutes. Open the notification curtain and find the Translation icon (sometimes called Translate or Wireless Display). If the icon is not there, go to Settings → Connection and Sharing → Broadcast. The system will automatically start searching for available devices on the LAN.
You also need to activate the reception mode on the TV screen, and on the Smart TV menu, this can be called Screen Share, Miracast, or simply "Mobile Translation." Once the devices find each other, confirm the connection on the TV remote.
- 📱 Open the broadcast menu on the Xiaomi smartphone.
- 📺 Turn on the reception mode on the TV (Screen Share).
- 🔗 Select the name of your TV in the list of available devices.
- ✅ Confirm the connection request if it appears on the screen.
It's worth noting that the quality of the picture depends on the speed of your Wi-Fi router. If the network is congested, you can see jerks of the image. For viewing video in high resolution 5 GHz network is preferable to a standard 2.4 GHz.
⚠️ Warning: When broadcasting via Miracast, the smartphone screen does not go out, which can lead to accelerated battery discharge.
💡
To reduce latency when streaming games, close background apps that consume traffic, such as torrents or cloud photo syncs.
Some older TVs may not support Xiaomi’s native protocol, in which case the system will suggest installing a special app on TV, following the instructions on the smartphone screen, a standard procedure for compatibility.
Using Google Chromecast technology
If your TV is running Android TV or has Chromecast built-in support, the process becomes even easier. This technology allows you to stream content from specific applications without duplicating the entire screen of your smartphone. This frees up the phone's processor and saves power.
To work, both devices must be on the same Wi-Fi network. Open an app like YouTube, Netflix or Google Photos. Find the rectangle icon with the waves in the corner, which is the broadcast button. Click on it and select your TV from the list.
Unlike Miracast, here the smartphone acts as a remote control, you can fold the app, answer the call or go to the menu, and playback on the TV will not be interrupted. Video quality is adjusted automatically depending on the speed of the Internet.
It is important to distinguish between two modes: broadcasting the browser tab and broadcasting the entire screen. In Google Chrome on Android, you can select the option “Translate the screen”, which will allow you to show the content of the site on a large display.
- 🌐 Make sure that your TV and phone are on the same Wi-Fi network.
- ▶️ Click the Cast icon in the app (YouTube, Movie Search).
- 📲 Select the target device to display the image.
- 🎮 Use your phone as a remote control to control playback.
If the broadcast button is not active, check for app updates. Often, support for new codecs and protocols is added through a software update.
Connection via HDMI cable and adapters
For users who want maximum stability and minimal latency (such as gaming), wired connectivity is the best choice. Xiaomi smartphones with USB Type-C port often support video output via the DisplayPort Alt Mode standard.
You'll need a special USB-C to HDMI adapter, just plug one end of the adapter into your phone and connect the other end to your TV via an HDMI cable, and the system automatically recognizes the external device and switches the video output.
In Settings → Connection & Sharing → Connecting to TV, you can select resolution and refresh rate. Some models, such as the Xiaomi 13 Pro or Mi 11 Ultra, support 4K output at 60Hz.
| Type of connection | Delay (Latency) | Quality. | Dependence on Wi-Fi |
|---|---|---|---|
| Miracast | Medium (50-100 ms) | Up to 1080p/4K | Tall. |
| Chromecast | Low (flow) | Up to 4K HDR | Tall. |
| HDMI (USB-C) | Minimum (<10 ms) | Up to 4K 60Hz | No. |
| DLNA | Low. | Depends on the file. | Medium |
Not all budget models support video output via USB. If nothing happens when you connect the adapter, it’s likely that your smartphone port is limited to USB 2.0 without a video output.
⚠️ Note: When using cheap adapters without additional power, the smartphone may not be able to pull the load (PD).
Once connected by cable, the phone can go to Desktop mode (if supported), turning the interface into a desktop-like experience, which is convenient for presentations or document handling.
Broadcasting through TV manufacturers' applications
Many TV makers are developing their own ecosystems that can run more stable than standard protocols, with Samsung’s SmartThings app, LG’s LG ThinQ app, and Sony’s Video & TV SideView app.
Install the app from Google Play on your Xiaomi. Once launched, the program will find the TV itself on the network. Inside the app, there is often a screen Translation or Smart View feature that uses proprietary algorithms to improve quality.
The advantage of these apps is that they can control not only the media, but the TV itself: adjust volume, switch channels, access to image settings, and that makes the smartphone a full-fledged universal remote.
Why can't the app see the TV?
In some cases, input is required. PIN-It's a security measure to prevent neighbors from accidentally connecting to your screen.
- 📥 Download the official brand app of your TV.
- 🔐 Allow access to the local network on the first run.
- 📡 Wait for the TV to be found on the list of devices.
- 🖥 Activate the screen duplication mode in the application menu.
Using native software often solves problems with black fields on the edges of the screen that can occur during standard broadcasting.
Customization of sound and audio systems
When you connect Xiaomi to your TV, it's important to set the audio output correctly. By default, sound can go through the phone's speakers, even if the picture is on the TV. To fix this, after connecting in the notification curtain or in the broadcast menu, select the audio output device.
If you use HDMI, the sound is digitally streamed directly to the TV or receiver. In the Sound and Vibration settings → Sound output, you can choose the priority device. For advanced users, Bluetooth Audio mode is available when the picture is on Wi-Fi and the sound is output to wireless headphones or speakers.
You can have a desynchronization situation where the sound is ahead of the video or lags, and in such cases, you can add audio delay to the broadcast settings (if the application allows), and you can also reboot the router.
💡
For home theater, use an HDMI or Chromecast with Dolby Digital support to get 5.1 or 7.1 surround sound through the receiver.
Remember to check the volume on both devices, and sometimes the TV is turned to the minimum and the phone is turned to the maximum, which creates noise.
Troubleshooting and troubleshooting
Even when set up correctly, there can be failures, and the most common problem is that devices can't see each other, and make sure that both devices are connected to the same network (2.4 GHz or 5 GHz) rather than to the guest or guest network.
If the broadcast is interrupted or the image is “crumbling”, try to reduce the output quality in the phone settings, and rebooting the Wi-Fi module helps: turn on and off the air mode.
In rare cases, the culprit is an antivirus or firewall on your smartphone that blocks outbound connections. Try temporarily disabling the protection for check.
☑️ Diagnostics of connection
Models with MIUI 12/13/14 shells are characterized by aggressive energy savings that can kill the background broadcasting process. Add the broadcast app to the battery exception list.
⚠️ Attention: If you are using VPN On a smartphone, local broadcasting won't work because traffic is going through an external server. VPN before connecting to the TV.
The last measure is to reset network settings on both devices, which will remove stored Wi-Fi passwords, but often resolve complex protocol conflicts.
