We will look at the algorithms of actions Step-by-step, so that even a beginner can cope with the task without difficulty.

Wireless connection via built-in Mi Cast function

The most popular and convenient way for owners of the Xiaomi ecosystem is to use the built-in Mi Cast feature (formerly known as “Translation” or “Wireless Display”). The technology is based on the Miracast standard, which allows you to transmit images without the loss of quality and delays that are characteristic of some streaming services. TV, Even if they are not made by Xiaomi.

If your router is broadcasting at 2.4 GHz and 5 GHz, make sure the phone and TV are connected to the same frequency, otherwise the devices may not be able to see each other. The setup process takes only a few minutes and does not require the installation of additional software.

To start streaming, open the control center on your smartphone (swipe down from the top right corner) and find the Broadcast icon or Mi Cast. If the icon is not in quick access, go to settings via the Settings path → Connection and Sharing → Broadcast. The system will automatically start searching for available devices within the network range.

⚠️ Note: When using wireless method in rooms with a large number of Wi-Fi networks (apartment buildings), picture instability is possible. In such cases, it is recommended to switch the router to a less busy channel or use a wired connection.

Once you find your TV on the list, click on its name. On the TV screen, you may request confirmation of connection — select "Allow" or "Accept" using the remote control. From now on, the smartphone screen will be duplicated on the large display.

Using Google Chromecast technology

Many modern Xiaomi Mi TVs run on the Android TV operating system, which has built-in support for Google Cast (Chromecast) technology. This method differs from Miracast in that it allows you not only to duplicate the screen, but to broadcast specific content (video, photos, music) directly from applications without loading the phone’s processor, which is especially useful for watching movies in high resolution.

To use this feature, make sure your smartphone has Google Home app or related Google Play Services installed. Unlike Mi Cast, here management is done through the interface of the source apps themselves, such as YouTube, Netflix or the Chrome browser.

The algorithm of actions is as follows:

• 📱 Open an app with the video or content you want to watch.
• 📡 Find the broadcast icon (a rectangle with waves in the corner), usually in the upper right or left corner of the interface.
• 📺 Select your Xiaomi TV from the list of available devices.

If you use Google Chrome on your phone, you can stream a whole tab. Click on the three-dot menu in the upper right corner of your browser and select Translate. In the window that opens, select Translate Screen for full duplication or Translate Tab for a specific site.

💡

To reduce latency when playing mobile games on your TV via Chromecast, close the background apps on your phone and turn off downloads to free up the Wi-Fi channel.

Image quality is often better when using Chromecast than when using direct screen duplication, since the TV itself decodes the video stream, receiving data directly from the Internet.

Connection via HDMI cable and adapters

If wireless methods are problematic or you need maximum stability and minimal latency (for example, for gaming), the best solution is wired connection. To implement this method, your smartphone must support video output technology, most often this is the MHL (Mobile High-Definition Link) standard or DisplayPort Alt Mode via a USB Type-C port.

You will need a special USB-C to HDMI adapter. Note that not all cables and adapters are the same: cheap models can only transmit charging or data, but not a video signal.

The connection process is as simple as possible:

1. Connect the HDMI cable to your TV and remember the port number (e.g. HDMI 1).
2. Insert the narrow end of the adapter into the smartphone charging connector.
3. Connect the adapter and TV HDMI cable.
4. On the TV remote, click the button to select the source of the signal (Input or Source) and select the appropriate port.

The image should appear automatically. In some cases, you may need to allow access on the phone screen, and the advantage of this method is that it does not depend on the speed of Wi-Fi and does not create additional strain on the wireless network.

⚠️ Note: When connecting through HDMI The phone may not charge if the adapter does not have an additional power port. For long sessions, it is recommended to use a Pass-Through Charging adapter.

Broadcasting through the Xiaomi TV Assistant app

For deeper integration with Xiaomi and Redmi smart TVs, the official Xiaomi TV Assistant app (formerly Mi Remote or Mi TV) not only allows you to control the TV as a remote control, but also act as a media server.

The app is available from Google Play or GetApps, and once installed and launched, it automatically scans the local network for compatible TVs, and requires authorization from a Mi Account account to ensure a secure connection between devices.

The functionality of the annex shall include:

• 🖼️ Broadcasting photos and videos from the gallery to the big screen.
• 🎮 Using a Smartphone as a Gamepad for TV.
• ⌨️ Enter text from the phone keyboard (convenient for searching in YouTube or browser on TV).

Using the official assistant guarantees better compatibility with branded TV features, such as voice control or access to the system settings of the screen, which is especially true for users who have multiple ecosystem devices in their home.

Solutions and Connection Problems

Despite the ease of settings, users may encounter difficulties: the TV can’t see the phone, the image twitches or there is no sound. Most often the problem lies in the network settings. Make sure that the router has turned off the AP Isolation function, which prevents devices inside the network from communicating.

If the connection is interrupted or the quality is low, try rebooting the router. It is also worth checking whether the router is not subject to speed limits for certain devices. In rare cases, resetting network settings on a smartphone through the Settings menu → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth helps.

Another common problem is the desynchronization of audio and video, which is often the case with cheap Bluetooth headphones coupled with wireless video, so you'd better switch the sound to the TV speakers or use a wired headset.

For older TV models that don't support Smart TVs, there are set-top boxes (such as the Mi TV Stick or Chromecast) that add this functionality, which plug into the HDMI port and operate on the same principles as the embedded systems.
