Modern multimedia capabilities allow you to turn the living room into a real cinema using only your smartphone and smart TV Xiaomi Mi TV or Redmi Smart TV. The process of broadcasting content has become much easier thanks to the introduction of wireless standards and the development of the Mi Home ecosystem.
However, users often face the nuances of customization, which depend on the version of the Android TV or PatchWall operating system. The correct network configuration and choice of the appropriate method of data transfer play a crucial role in the stability of the connection. In this guide, we will discuss in detail all the current ways that will provide a quality picture without delay and desynchronization of sound.
Preparation of devices for wireless connection
Before you start setting up, make sure that both devices are in the same network conditions. A critical condition is to connect your smartphone and TV to the same Wi-Fi network. If your router is giving signals at 2.4 GHz and 5 GHz with different names, make sure that the gadgets are connected to one of them, ideally to the 5 GHz band for high speed.
Check the software’s relevance on both devices. On Xiaomi TV, go to Settings → About TV → System information and check for updates. Outdated Wi-Fi module drivers can prevent devices from being found on the local network.
It is also necessary to temporarily disconnect VPN-Proxy connections often change the virtual address of the device, which causes the TV to stop “seeing” the phone on the local network, believing it is in another geographical location.
⚠️ Note: Guest Network (WIFI) often blocks the ability to exchange data between devices within the LAN.
Make sure the detection feature is enabled on the TV. Depending on the model, this can be called Cast, Broadcast or Screen Mirroring. Usually this feature is active by default, but after resetting, it needs to be enabled manually through the Application → Wireless Transmission application.
Broadcasting through the built-in Translation function (Miracast)
The most versatile method, which does not require additional software, is based on Miracast technology, which is supported by most Android smartphones and Xiaomi TVs with PatchWall or Android TV shells, and allows you to duplicate the screen in real time, which is ideal for showing presentations or viewing photo galleries.
To start, open the notification curtain on your smartphone and look for the Broadcast, Transfer or Smart View button (name depends on the phone manufacturer). Once you activate the search, the device will start scanning the available receivers.
As soon as your Xiaomi Mi TV appears on the list, click on it. On the TV screen, you may see a request to confirm the connection - select "Allow" from the remote control. From now on, the image from the smartphone will be completely cloned to the large screen.
- 📱 Open the control center on your smartphone (swipe down).
- 📡 Click the "Translation" or "Projection" button".
- 📺 Select your Xiaomi TV from the list of found devices.
- ✅ Confirm the connection on the TV screen if you receive a request.
It should be noted that when using Miracast smartphone does not block the screen, but the battery consumption increases significantly. Miracast technology transmits video stream directly through Wi-Fi Direct, bypassing the router, which reduces latency, but requires close location of devices.
☑️ Checking before connection
Using Google Chromecast technology
Owners of Android TVs can use Google Chromecast’s built-in functionality, which differs from Miracast in that it doesn’t broadcast the entire screen, but rather specific content from apps (YouTube, Netflix, Kinopoisk), allowing the phone to be used for other tasks while watching.
To work, make sure your smartphone has a Google Home app installed, which is necessary for initial setup and management of the casting process. Open the app, find your TV in the list of devices, and make sure that the "Translation of my screen" status is active.
To run a video, open a support app (like YouTube) on your phone. Click on the Chromecast icon in the video corner and select your Xiaomi TV. The video will play on a smartphone-controlled TV.
This is a way to provide better picture quality, because the TV itself downloads the stream from the Internet, and the phone acts only as a remote, which reduces the load on the smartphone processor and saves battery power.
⚠️ Note: Chromecast requires a stable Internet connection on the TV itself, and if the router blocks access to Google’s external servers, the broadcast will not start.
Third-party applications for enhanced capabilities
If standard methods are unstable or require additional features (such as file transfer without compression), you should turn to third-party solutions, the leader in this niche is the Xiaomi Mi Remote application or universal utilities like Cast to TV and LocalCast.
LocalCast allows you to transfer almost any video file stored in the phone’s memory to the TV, even if the format is not supported by the built-in TV player.
Send Files to TV is a great application for transferring photos and documents. It works on the Wi-Fi Direct protocol and provides a very high speed of copying files between devices without loss of quality.
The table below compares popular content transfer methods:
| Method | Delay. | Quality. | Battery consumption |
|---|---|---|---|
| Miracast | Low. | High. | High-pitched |
| Chromecast | Minimum | Maximum. | Low. |
| HDMI Cable | Absent. | Maximum. | Charging. |
| DLNA (Local Area Network) | Medium | Depends on the file. | Medium. |
Using third-party software is especially important for older TV models, where embedded protocols may not work properly, but remember that free versions of apps often contain ads.
What if there is sound and no image?
Wired connection via HDMI and USB-C
To achieve maximum stability and quality, especially when viewing 4K HDR content, nothing beats a wired connection, which eliminates any interference from neighboring Wi-Fi networks and ensures data transfer with maximum bandwidth.
You will need a USB-C to HDMI adapter. Note that the USB-C port on your smartphone should support the DisplayPort Alt Mode standard. Budget phone models may have a port only for charging and data transfer, but not for displaying images.
Connect the adapter to your phone, and connect the HDMI cable to your TV. Switch the signal source on your TV to the appropriate HDMI 1 or HDMI 2 port. The image will appear automatically, often the phone will go into special mode.
- 🔌 Prepare the adapter. USB-C on HDMI cable HDMI.
- 📺 Connect the cable to the port HDMI on Xiaomi TV.
- 📲 Connect the adapter to your smartphone.
- 🖥️ Select the correct source of the signal (Source) on the TV remote.
The advantage of this method is that the phone is simultaneously charged from the network (if the adapter has a power port), which allows you to watch long movies without fear of draining the device.
⚠️ Note: Not all cables HDMI It's the same for transmission. 4K 60Hz images make sure you use a standard cable HDMI 2.0 or higher (High Speed).
Solving Connection and Quality Problems
Even if you set it up properly, you can have some kind of failure, like desynchronization of sound, artifacts on the screen, or connection breaks, and most often, the problem is that you have congested Wi-Fi, and try to reboot your router and change the channel in its settings.
If the image twitches, try lowering the output resolution on your smartphone. Go to Settings → Screen. → Resolution and select a lower option, or disable the option HD-quality in the settings of the broadcast itself.
In some cases, cleaning the cache of the Wireless Transfer system application on your TV helps. Go to Settings → Apps → All Apps → Wireless Transfer → Clear the data.
💡
If the broadcast is permanently interrupted, try temporarily disabling Bluetooth on your smartphone. In some chipsets, Wi-Fi and Bluetooth modules work at the same frequency and create interference.
It’s also worth checking if the router is enabled with AP Isolation, which, if it’s active, can see the router on the network but can’t communicate with each other, making it impossible to stream.
💡
The stability of wireless broadcasting depends on the quality of the Wi-Fi signal and the absence of physical obstacles between the router and devices.
