The modern smart home ecosystem requires the integration of all devices, and the bundle of a smartphone with a TV is one of the most popular features. Owner Xiaomi Mi TV or Redmi Smart TV gets at his disposal not just a large screen, but a powerful multimedia center controlled from the palm of the hand. The synchronization process allows access to the broadcast of content, use of the smartphone as a remote control and advanced system settings through a mobile application.
There are several ways to connect, each with its own technical features and use cases. Wireless technologies such as Mi Remote and Chromecast allow you to instantly display photos and videos on the big screen, while wired connection via HDMI provides maximum signal stability. Understanding the differences between these methods will help you choose the best option for your situation.
In this article, we will take a look at all the available methods for integrating Android and iOS mobile devices with the Chinese manufacturer’s TV panels. You will learn about the nuances of DLNA configuration, the features of working through an infrared port and how to fix typical connection errors. Ready to work will take only a few minutes if you follow the proven algorithms of actions.
Preparation of equipment and network
Before starting the synchronization process, you need to make sure that all devices are in a single information space. A critical condition for most wireless protocols is to connect your TV and smartphone to the same Wi-Fi network. If the router is sending out a signal at 2.4 GHz and 5 GHz with different network names (SSIDs), both gadgets must be connected to the same name.
Check the software's relevance on both devices. Xiaomi and Redmi TVs running Android TV or PatchWall's proprietary shell often come out with updates to fix vulnerabilities in data protocols. Go to the settings menu and check for system updates.
⚠️ Warning: If your router is set up to isolate customers (AP Isolation, devices on the network will not see each other. Make sure that this feature is disabled in the router settings, otherwise the phone will not find a TV.
The process of finding and shaking hands between devices can consume a significant energy resource, especially when using Bluetooth Low Energy or active Wi-Fi Direct. It is recommended to have chargers on hand or make sure that the charge level exceeds 20%.
☑️ Preparation for connection
Using the Mi Remote application for management
One of the most popular ways to interact is to turn a smartphone into a universal remote control, using the official Mi Remote (or Mi Remote Controller) app, which is pre-installed on many Xiaomi, Redmi and POCO smartphones, but is available for download on Google Play and other models.
The binding process starts with launching the application and selecting the type of device, you need to find the category "TV" and the manufacturer "Xiaomi", then the system will suggest choosing the method of connection: through an infrared port (if you have one in your phone) or via Wi-Fi. For modern Smart TVs, it is preferable to choose Wi-Fi, since this provides two-way communication and the ability to enter text from the phone keyboard.
When you select a network connection, the app will automatically scan the local network and find available TVs, you will only need to confirm the code displayed on the screen, or click the pairing button on the virtual remote, and once successfully linked, the phone will be able to completely replace the physical remote, including voice search functions through Google Assistant.
What to do if the IR port is not working?
Broadcasting the screen via Chromecast and Google Home
Chromecast built-in technology is the standard for the Android TV ecosystem that Xiaomi Mi TVs are equipped with.It allows you to stream the contents of the smartphone screen or individual browser tabs directly to the large display.To implement this feature, the Google Home application must be installed on an iPhone or Android smartphone.
Once you install the app, launch it and wait for the TV to be detected. Click on the device icon and select "Cast screen"; the system will request permission to record the screen content and transmit audio; once confirmed, the image from the phone will appear on the TV with minimal latency.
This method is particularly useful for presentations, photo albums or games that do not support the native Smart View function. For video transmission in 1080p or 4K resolution, it is recommended to use the 802.11ac network (Wi-Fi 5) or later.
Connecting iPhone via AirPlay
Apple device owners can take advantage of AirPlay proprietary technology, which is now supported by many models of Xiaomi and Redmi TVs based on Android TV. This allows you to broadcast videos, photos and even duplicate the screen without installing additional applications on the TV itself, if the function is activated in the settings.
To activate, you need to make sure that your TV settings include AirPlay support. Usually this option is in the Settings → Applications → AirPlay or in the Quick Settings menu. On an iPhone, you just need to open the Control Point, click on the Screen Replay button and select your TV from the list of available devices.
The first connection on the TV screen may have a four-digit code that you need to enter on the iPhone to confirm trust, and once successfully linked, the devices will connect automatically when they are on the same network, which ensures high-resolution video transmission stability.
⚠️ Note: AirPlay can be called differently depending on the region and firmware version, and in some models it is integrated into Apple's HomeKit service, which requires additional authorization through the Home app on iOS.
Wired connection via HDMI and adapters
When wireless connectivity is unstable or maximum image quality is required without compression, wired connectivity is the best solution. Modern smartphones with USB Type-C port will require a special Type-C to HDMI adapter that supports MHL or Alt Mode.
The connection is simple: one end of the adapter is inserted into the phone, and the second connects the HDMI cable that goes to the TV. On the TV remote, you need to switch the signal source (Input) to the corresponding HDMI 1 or HDMI 2 port. The image will appear automatically, often in mirror mode.
This method is ideal for gaming, as it provides minimal input lag, and for watching 4K HDR video, which may not be supported over Wi-Fi due to channel bandwidth limitations.
💡
Use HDMI 2.0 or 2.1 cables to support 4K resolution at 60Hz. Older HDMI 1.4 cables can limit frame rates to 30Hz or reduce color quality.
Comparison of Connection Methods and Problem Solving
The variety of ways to connect can be confusing for the user, so it is important to understand which method is best suited for a particular task. Below is a comparative table of the main characteristics of each of the methods considered.
| Method | Type of connection | Delay (Latency) | Video quality |
|---|---|---|---|
| Mi Remote | Wi-Fi/IK | Low (management) | Doesn't broadcast video |
| Chromecast | Wi-Fi | Medium | Up to 4K (network dependent) |
| AirPlay | Wi-Fi | Low/Mediocre | High (Apple Lossless) |
| HDMI cable | Wired | Minimum | Maximum (no compression) |
If the TV doesn't show up on the list of available devices, try restarting the router. Often the problem is overflowing the table. ARP-The router's addresses, which causes new connections to be blocked, also helps clear the cache of the Google Play Services app on the phone.
In some cases, antivirus programs or firewalls on your smartphone may block local network detection. Try temporarily disabling network protection or adding a TV to the exception list. Make sure that the TV does not have a guest network mode that isolates devices from each other.
💡
For all wireless functions to work smoothly, it is critical that the TV and phone are on the same subnet (the same is true). IP-gateway address) rather than simply being connected to a single router via different frequency ranges with isolation.
