Modern multimedia systems require flexibility, and owners of smart technology often face the need to stream content from a mobile device to a large screen. Xiaomi Mi TV 4A is a popular model that supports many wireless data protocols, but the setup process can seem difficult for beginners. Understanding the principles of Mi Home and the Android TV operating system opens up access to advanced features of your device.
In this article, we will take a look at all the ways you can connect your smartphone and TV, including wired and wireless options, learn about the nuances of Miracast and Chromecast, and get answers to questions that arise when there is no stable signal.
Before you start syncing, make sure both devices are working correctly and have up-to-date software versions. For wireless connections, it is critical that both Xiaomi phone and TV are on the same local Wi-Fi network. Ignoring this basic requirement is responsible for 90% of all connectivity issues.
Device preparation and network verification
The first step should always be to diagnose the network environment, as the router is the link between the gadgets. Go to your router's settings and make sure that the client isolation function is turned off, otherwise the devices will not simply "see" each other on the local network. Also check that the router does not have a limit on the maximum number of connected devices, which is often found in public networks or when using guest modes.
Update the software on the Xiaomi Mi TV 4A by going to the settings menu. Often manufacturers release patches that fix media protocol errors, so you should not ignore this step. On the smartphone, it is also recommended to update the system components of Google Play Services, which are responsible for the broadcast function.
For wireless technology to work smoothly, it is advisable to use a 5GHz frequency if your router and TV support this standard, which will provide higher channel bandwidth and reduce the likelihood of image artifacts or sound dissynchronization.
☑️ Checking before connection
⚠️ Attention: Use VPN-When trying to connect to a TV, the devices are often blocked from being detected on the local network.
Use of the built-in Cast function (Wireless connection)
The easiest and most common method is to use the native streaming feature built into the Android shell. On Xiaomi TVs, this feature is often called Translation or Cast, and it is based on Google Chromecast built-in technology. You don't need to install additional apps if your smartphone is running Android version 5.0 and higher.
To start the process, open the notification curtain on your smartphone and look for the “Translation”, “Smart View” icon (on Samsung) or “Projection”. After scanning the network, the phone will offer a list of available devices. Select your Xiaomi Mi TV 4A from the list, and the TV screen will see a request for confirmation of connection, which must be received by the remote.
If automated search doesn't work, try using Google Home, which allows you to control smart home devices and has a built-in screen mirroring feature. Click on your TV icon in the app and select "Translate screen," a method that often works more stable than the system button in the curtain.
- 📱 Open the Quick Access settings on your smartphone.
- 📡 Choose the option of wireless projection or Smart View.
- 📺 Wait for the Xiaomi Mi name to appear TV 4A list.
- ✅ Confirm the pairing on the TV screen.
It is worth noting that when using the built-in Cast, the image is transmitted in high quality, but there may be a slight delay, which is normal for this protocol.
Broadcasting through Mi Remote and the Mi Home ecosystem
Owners of Xiaomi smartphones and devices with MIUI+ or Mi Home installed have access to advanced management features. Mi Remote, which is often pre-installed on Xiaomi phones, allows not only remote control, but also media content broadcasting. This is especially convenient if Google’s standard protocol is unstable.
Launch the Mi Remote app and add your TV to the list of devices. After successfully pairing over Wi-Fi (the TV must be turned on), the remote interface will have a broadcast button or the ability to select files to play, the system will select the optimal codec for the transmission of the video stream.
Xiaomi ecosystem users can access the “Mi Play” feature or similar services that allow you to transfer photos and videos from the gallery with a single touch. The MIUI gallery interface often displays a TV icon in the corner of the screen when selecting a photo, which duplicates the Cast function, but is optimized specifically for the brand’s technology.
⚠️ Note: Mi Remote requires an IR port on your smartphone to initially configure the remote, but for transferring media files over Wi-Fi, the presence of an IR emitter is not necessary.
The advantage of using branded utilities is better optimization for the processors of Xiaomi TVs. This can reduce the load on the network and reduce the amount of buffering when watching heavy TV. 4K-content.
Connection through HDMI-cable
If wireless connection is not possible or you need maximum image quality without compression, use a wired method. For this you will need a USB-C to HDMI adapter (or Lightning to HDMI for iPhone), since it is impossible to directly connect the phone with an HDMI-HDMI cable due to different connectors.
Connect the adapter to the smartphone, and then connect it with a cable HDMI with a Xiaomi Mi TV TV 4A. Switch the signal source on the TV to the appropriate port (e.g, HDMI 1 HDMI The image should appear automatically if the phone supports the technology. MHL DisplayPort Alt Mode.
It is important to understand that not all smartphones of the mid- and budget segment support the output of video signals through the Internet. USB-Flagship models usually have this feature, but before buying an adapter, it is worth checking the specification of your device. If there is no image, try changing the output resolution in the phone settings.
| Type of connection | Quality. | Delay. | Difficulty |
|---|---|---|---|
| Wi-Fi (Cast) | High (up to 1080p/4K) | Medium | Low. |
| HDMI Adapter | Maximum. | Absent. | Medium |
| DLNA Player | Depends on the file. | Low. | Medium |
Why is there no sound when connected via HDMI?
Broadcasting via DLNA and third-party players
The DLNA (Digital Living Network Alliance) method is ideal for playing files (video, music, photos) already downloaded to your phone without mirroring the entire screen. To do this, you need to install a DLNA-enabled player app on your Xiaomi Mi TV 4A, such as S/P No. 1 or a built-in Media Player.
On the smartphone will also need an application that can work with DLNA-You can use servers, or you can use the built-in Translation in the gallery, and you can open the video file on your phone, you can click the Cast button, and you can select the TV. Unlike Miracast, it only transfers the file itself, and the phone can be used for other tasks.
Popular video players like VLC or MX Player have built-in support for Chromecast and DLNA. Run the video in the player, click on the broadcast icon and select your Xiaomi. This is the best way to watch movies in formats that are not supported by standard system tools, such as MKV with specific subtitles.
- 📂 Install a compatible media player on TV and phone.
- 🔗 Make sure that devices are on the same network.
- ▶️ Launch the file and select the broadcast icon.
- 🎬 Enjoy watching without loading on your smartphone.
The main advantage of DLNA is the ability to control playback from the phone, pausing or rewinding, while the smartphone battery is consumed minimally, since the TV is decoding.
💡
If video slows down when streaming over DLNA, try lowering the file bitrate or switching the router to a less loaded channel (1, 6, or 11 for 2.4 GHz).
The solution: problems and their elimination
Even if you set it up properly, there may be some problems with software conflicts or network hardware. If the Xiaomi TV isn’t visible on the list of available devices, try restarting the router completely shutting it down for 10-15 seconds, which will clear the DNS cache and update the routing tables.
A common problem is to desynchronize sound and image, and this is treated by changing the audio output settings in the TV menu: switch from Automatic to PCM or HDMI, and check if the phone is power-saving, which can limit the Wi-Fi module.
In some cases, resetting your network settings on your smartphone helps, and it won't delete your data, but it will return the network settings to factory values, which often solves the problem of invisibility of devices on the local network, and you will need to reset your Wi-Fi password after the reset.
⚠️ Note: If you have frequent connection breaks, check if you are using a dual-band router with the same network names (SSID) For 2.4 and 5 GHz, divide them into different names to avoid confusion when switching frequencies.
💡
Rebooting the router and cleaning the app cache on the TV solve 80% of device detection problems.
