Modern multimedia capabilities allow you to turn any Smart TV into a full-fledged entertainment center, but this often requires the output of images from a mobile device. Owners of Xiaomi equipment often wonder how to synchronize your smartphone or tablet with a large screen to watch movies, photos or games. The process of pairing can seem difficult only at first glance, but modern data transfer protocols make this procedure as automated as possible.
There are several proven ways to connect your gadget to your TV, each with its own advantages: You can use wireless technologies like Wi-Fi Direct or Chromecast built-in, or you can use a classic cable connection via an HDMI port. The specific method depends on your TV model, Android TV or PatchWall operating system version, and the type of smartphone you use.
In this guide, we will take a detailed look at all current connectivity methods, focusing on network settings and eliminating common errors. You will learn how to activate screen duplication mode, what applications are needed for stable operation and why sometimes wireless connection is unstable.
Preparation of equipment and Wi-Fi network
Before you start setting up, you need to make sure that all devices are in the same connection conditions, a fundamental requirement for most wireless broadcast protocols to work. If your smartphone is connected to 4G/5G mobile Internet and your TV is running via a Wi-Fi router, direct detection of devices will not be possible.
Make sure your router supports 2.4GHz or 5GHz frequency standards. For high-resolution video, especially in 4K, it is recommended to use the 5GHz band, as it provides higher bandwidth. However, it is worth remembering that the range is shorter and walls can significantly weaken the signal.
⚠️ Warning: Make sure the router has disabled the “Customer Isolation” feature» (AP If this option is active, devices connected to the same network will not “see” each other, making wireless broadcasting impossible.
Also check the operating system version on your mobile device. Modern mirroring features often require an up-to-date version of Android or iOS to work properly. Outdated software may not support the necessary codecs or security protocols, leading to errors when trying to connect.
Wireless connection through built-in Android features
The most common way is to use the built-in functionality of the operating system. In Xiaomi smartphones with the shell MIUI or HyperOS, this feature is often called “Translation” or “Wireless Monitor”. Xiaomi TVs running on Android TV automatically support the Google Cast protocol, which makes it easier to find devices.
To start the broadcast, open the notification curtain on your smartphone and find the Translation icon. If it's not on the home screen of the Quick Access menu, click on a pencil or three dots to edit the list and add the widget you want, and once activated, the phone will start scanning the available devices on the local network.
When the name of your TV appears in the list (usually a TV model or a name given in the settings), click on it. A connection confirmation request may appear on the TV screen, which must be received by the remote control, and then the image from the smartphone will be duplicated on the large screen in real time.
💡
If the phone doesn't find the TV, try restarting the router, and often the problem is the router's overcrowded network cache, which blocks discovery packets.
It is important to note that when using this method, the smartphone screen should be turned on, as the video stream is generated in real time.This can lead to faster battery discharge, so it is recommended to keep the device on charge for long periods of viewing.
Using the Mi Remote app and the Mi Home ecosystem
Owners of Xiaomi equipment should pay attention to branded applications that expand the functionality of interaction. Mi Remote app is primarily designed to control the TV using a smartphone, simulating the remote control, but it also allows you to quickly transfer media files.
For deeper integration, use the Mi Home app, which allows you to not only manage your smart home, but also find devices online. If your TV supports DLNA, you can stream photos and videos directly from the gallery by selecting the output device from the Send to menu.
- 📱 Download the official Mi Home app from Google Play or App Store.
- 🔗 Sign up for your Mi Account and add your TV to your device list.
- 📂 Open the media file in a gallery or video player and select the broadcast icon.
- ✅ Confirm the connection on the TV screen if required.
The advantage of using branded apps is to better optimize and support specific features of Xiaomi TVs, such as voice control or adjusting image settings during broadcast.In addition, the app can offer a firmware update to the TV, which often solves compatibility problems.
Why does the Mi Home app not see TV?
Broadcasting via Google Home and Chromecast
Because many Xiaomi TVs run on a pure Android TV operating system, they have built-in support for Chromecast technology, which allows you to stream content from applications that do not have their own interface for Smart TVs, such as browsers or specific video players.
To work with this method, the Google Home app must be installed on your smartphone. Once you install and configure the device, the app will display your TV icon, click on it, then select the "Cast my screen" option.
| Parameter | Description | Requirements |
|---|---|---|
| Protocol | Google Cast / Chromecast | Android 5.0+ / iOS 11+ |
| Quality. | Up to 4K HDR | Stable Wi-Fi 5 GHz |
| Delay. | Low (for video) | Not suitable for dynamic games |
| Battery | Average expenditure | Phone screen is active |
This method is ideal for watching videos from YouTube, Netflix or other streaming services, since the video file is transmitted directly from the server to the TV, bypassing the phone, which reduces the load on the smartphone processor and saves battery power.
💡
Using the built-in Chromecast provides the best picture quality when watching online video, as the TV itself decodes the stream without loading the smartphone.
Cable connection via HDMI and adapters
If the wireless connection is unstable or requires maximum image quality without compression, the best choice will be a cable connection. For Xiaomi smartphones with a USB Type-C port, you will need a special USB-C to HDMI adapter.
It’s important to consider that not all smartphones support video transmission via USB.MHL or DisplayPort Alt Mode must be hardware-implemented on your device. Xiaomi flagship models typically support this feature, whereas it’s often absent in budget segments.
Checking for HDMI support:
1. Connect the adapter to the phone.
2. Connect the HDMI cable to the adapter and TV.
3. switch the signal source to the TV to the appropriate HDMI port.
4. If the image appears, there is support.The advantage of cable is that it has no latency, which is critical for gaming, and that the quality of the image is native, without the compression artifacts that are characteristic of wireless protocols when the signal is bad.
Configure permission and frequency of update
Once you've successfully connected, you need to set up your output settings for comfortable use. Go to your phone settings, Connected Devices → Connection settings (the path may vary depending on the version of MIUI).
You should set the resolution to the TV matrix. If you have a 4K TV, but the phone is 1080p, the picture will be stretched programmatically, which can reduce font clarity. Conversely, if the phone is more powerful, you can try to set 3840×2160 at 60Hz.
⚠️ Warning: Setting too high an update rate or resolution that is not supported by the TV can result in a black screen.In this case, unplug the cable or restart the phone to reset the display settings.
Also note the aspect ratio: some old apps or games may not show correctly on the wide screens of modern TVs, leaving black bars on the sides. The TV settings often have zoom modes ("Size of the screen", "Original", "Wide") that help to correct this nuance.
☑️ Image quality check
Troubleshooting and troubleshooting
Even when you're set up correctly, you can have technical difficulties, and one of the most common problems is that you can desynchronize your sound and your image, and this often happens when you overload your Wi-Fi channel, so you can try to turn off other devices that consume traffic, or switch to a cable.
If the connection is cut off immediately after the broadcast begins, check the power saving settings on the phone. Aggressive energy saving modes can block the background processes needed to maintain a stable Wi-Fi Direct or Chromecast connection.
- 🔄 Reboot your router, phone, and TV – it solves 80% of network problems.
- 📡 Get closer to the router if the Wi-Fi signal is weak.
- 🔒 Check if the antivirus or firewall is blocking the local connection.
- 📺 Update the TV firmware through the Settings menu → On TV. → Updating the system.
In rare cases, the problem may be codec incompatibility. If the video is played but no sound, try changing the format of the audio stream in the settings of the player app or the TV itself (for example, switch from Dolby Digital to PCM).
