Modern TVs Xiaomi and Mi TV open up wide multimedia opportunities for users, but often there is a need to display the image from the smartphone to the big screen.
This may be required to view photos, video conferencing, or play games with better graphics, and there are several proven methods that allow you to sync devices without unnecessary complexity.
In this article, we’ll take a closer look at wireless and wired connectivity options, and look at typical setup errors.You’ll learn to use Miracast and Chromecast for instantaneous content streaming.
Preparing devices for synchronization
Before starting the process, it is important to make sure that both devices are working correctly and within sight of each other, and most connectivity problems arise from the banal disregard of basic network requirements.
Make sure your smartphone and TV are connected to the same Wi-Fi network. If the router is signaling at 2.4 GHz and 5 GHz, both gadgets must be on the same subnet for stable detection protocols.
- 📱 Check if the Wi-Fi module on your smartphone is enabled and if geolocation is activated (GPS), In Android, this is often required to find devices.
- 📺 Make sure that the latest version of the PatchWall or Android operating system is installed on Xiaomi TV TV.
- 🔋 Charge your mobile device to at least 30% so that the setup process is not interrupted due to energy savings.
Note that older router models may not properly handle the multicast traffic needed to find a TV, in which case a router reboot often solves the problem of the device disappearing from the list of available devices.
☑️ Checking before connection
Wireless connection via built-in Chromecast
The most popular way to stream content is by using Google Cast technology, built into most Xiaomi TVs, which is ideal for YouTube, Netflix and browsers that support the protocol.
You don’t need to install additional apps if your smartphone already has Google services, and the process starts directly from the interface of the app.
Open a video or a photo, click on the Cast icon and select your TV from the list. The connection is set in a few seconds, after which the phone turns into a remote control.
💡
If the stream icon doesn’t appear, make sure that the YouTube or Google Photos apps are updated to the latest version through the Play Market.
The quality of the transmission depends on the speed of the Wi-Fi channel. To view video in 4K, it is recommended to use the 802.11ac (5 GHz) network to avoid buffering.
Duplicate the screen of the smartphone (Miracast)
If you need to bring to your TV exactly what is happening on your phone screen (such as the settings menu or a game without Cast support), use the Broadcast or Miracast feature.
Unlike the Chromecast, here the image is encoded and transmitted in real time, which can create minimal latency. On Xiaomi TVs, this feature is often built into the system.
On your smartphone, lower the notification curtain and look for the Broadcast, Smart View or Wireless Monitor button.The name depends on your phone model (Samsung, Xiaomi, Huawei).
⚠️ Attention: When you duplicate the screen, the default sound can go through the phone's speaker. Switch the output to the Bluetooth settings or the app's menu itself.
Once you select the TV in the list, you may see a request on the Mi TV screen to confirm your connection. Use the remote to allow access.
Using the Mi Remote application for management
For full control of the TV, not just for broadcasting pictures, the official Mi Remote or Google Home app is best suited, which turns the smartphone into an advanced remote with the ability to enter text.
Download the app from Google Play and search for your devices, and it will find your TV on the local network.
| Function | Description | Convenience |
|---|---|---|
| Virtual keyboard | Enter text to search in YouTube or browser | High. |
| Voice search | Control via smartphone microphone | Average. |
| File transfer | Sending photos and videos to TV | High. |
| Game mode | Using a phone gyroscope as a steering wheel | Low. |
Some Xiaomi phones are equipped with an infrared port (IR Blaster), in which case the Mi Remote app can control the TV even without a Wi-Fi connection, simulating a conventional remote.
What to do if your phone can’t see TV?
Wired connection through HDMI-cable
For tasks that require minimal latency and maximum quality, use a wired connection. You will need a USB-C to HDMI adapter or an MHL adapter.
Connect the cable to your smartphone and HDMI free port on your TV. Switch the signal source to the TV with the Input button or through the source menu.
This method ensures a stable picture without compression artifacts, which is critical for games or presentations, but the phone will discharge faster if you do not use a charging adapter.
- 🔌 Use certified cables no longer than 2 meters long to avoid signal loss.
- ⚡ It is advisable to connect the phone to the charger in parallel with the transmission of video.
- 🎮 For games, horizontal screen orientation and disabling notifications on the phone are recommended.
⚠️ Note: Not all smartphones support video output via USB-C. Technology should support the standard MHL DisplayPort Alt Mode.
Bluetooth settings for sound transmission
Although Bluetooth is rarely used for video transmission because of its low bandwidth, it's great for organizing a wireless audio system. You can connect your phone to your TV as if it were a speaker.
Go to the settings of the Xiaomi TV in the section Settings → Remote and accessories → Add accessory. Enable search on the phone and pair.
This is convenient if you want to listen to a podcast or music through a quality TV acoustic system without being distracted by the visual range.
💡
Always use Wi-Fi to watch videos (Chromecast/Miracast) or HDMI-cable because Bluetooth will not synchronize audio and video.
