Modern smartphones have high-resolution screens, but sometimes you want to share what you see with friends or family on the big screen. Owners of the popular Xiaomi Mi TV 4A often face the need to broadcast content, but do not know what method will be most effective. Fortunately, the Android ecosystem offers many built-in and third-party solutions for this task.
In this article, we will take a look at all the available methods, from wireless protocols to cable connectivity, and learn how to set up Miracast, use Google Cast technology, and even connect your device via a physical HDMI port, which will allow you to enjoy photos, videos and games in the highest quality possible.
Some methods require minimal preparation, such as installing additional applications, while others work out of the box. It is important to understand the difference between broadcasting (duplication) and sending media content (when the phone acts as a remote).
Before you start, make sure your hardware is working properly. Sometimes the connection problems are not software settings, but the banal lack of firmware updates. Both devices must be on the same Wi-Fi network for wireless protocols to work, which is a critical condition.
⚠️ Note: When using wireless data transmission methods, picture quality may depend on the load of the Wi-Fi channel. If there are delays, try to free the air from other active downloads.
Use of the built-in "Translation" (Wireless Display) function
The easiest and fastest way to do this without having to install any additional software is to use the built-in MIUI shell or pure Android functionality. The technology, known as Miracast, allows you to duplicate the screen of your smartphone on your TV in real time. On Xiaomi Mi TV 4A, this receiver is often already integrated into the system.
To get started, you need to activate the standby mode on the TV, depending on the firmware version, it can be a separate application or item in the signal source menu, and then the phone will start searching for available devices within the network range.
☑️ Readiness for wireless broadcasting
The adjustment process is as follows:
- 📺 On the TV remote, click the source select button and find the “Wireless Display” item or run the application of the same name.
- 📱 On your smartphone, lower the notification curtain and find the icon “Translation”, “Projection” or “Cast».
- 🔗 In the list of available devices, select your Xiaomi TV 4A.
- ✅ Confirm the connection if a request for permission to connect appears on the TV screen.
It's worth noting that when you duplicate the screen, the smartphone keeps working and all the notifications will be visible on the big screen. This can be uncomfortable when watching movies, but great for presentations or showing a photo album. If the connection is interrupted, try bringing the phone closer to the router.
⚠️ Note: The “Translation” function can significantly consume the battery of the smartphone, since the Wi-Fi module operates in a constant high load mode.
What to do if the TV is not found?
Streaming through Google Home and Chromecast built-in
The Android TV platform on which Xiaomi Mi TV 4A is based has deep integration with Google services.This means you can use the Chromecast protocol to transfer content. Unlike Miracast, it often transmits not a picture from the screen, but a link to the stream, which unloads the phone.
To implement this method, you will need the Google Home app, which you can download from the official Play Market Store. Once installed, the app will automatically scan the network and find your TV. This is one of the most stable ways to stream videos from the Chrome browser or YouTube.
The algorithm of actions is very simple:
- 📲 Open the Google Home app on your smartphone.
- 📺 Find your Xiaomi listing TV 4A and press it.
- 🖥️ Select the option “Cast my screen).
- 🔊 The sound will also be transmitted to the TV, providing a full immersion.
The advantage of this method is that you can control playback from your phone without interrupting the stream, so you can fold an application, answer a call, or play another game, and the video on the TV will continue to play without interference.
💡
Use the Chrome browser to stream tabs: Open a three-dot menu and select Translate to bring the contents of a particular tab to the big screen.
Connection through HDMI-cable)
If wireless networks are overloaded or you want maximum image quality without compression artifacts, consider a wired connection. For this you will need a special adapter, since modern smartphones rarely have a full HDMI port.
The owners of USB Type-C phones are the most fortunate. Many flagship models support the MHL or DisplayPort Alt Mode standard, which allows video transmission directly through a cable adapter. Models with a Micro-USB connector will require more sophisticated OTG-enabled adapters.
The connection scheme looks like this:
- Connect the USB-C to HDMI (or Micro-USB to HDMI) adapter to your smartphone.
- Insert the HDMI cable into the adapter and into the free port on the back of the Xiaomi Mi TV 4A.
- Switch the signal source on the TV to HDMI 1 or HDMI 2.
- The image should appear automatically; if not, check the resolution settings in the phone menu.
This method is ideal for gaming, as input lag is minimal. However, it is worth remembering that not all budget smartphones support video output through the charging port.
| Type of connection | Quality. | Delay. | Battery consumption |
|---|---|---|---|
| Miracast (Wireless) | High (depends on Wi-Fi) | Medium | High-pitched |
| Google Cast | Up to 4K (stream) | Low. | Medium. |
| HDMI Cable | Maximum. | Minimum | Low (charging) |
Use of third-party applications for duplication
Embedded tools don’t always work perfectly with all phone models. Sometimes, Xiaomi’s Android TV system may not see another manufacturer’s device, and in such cases, specialized apps that are installed from the Google Play store directly onto the TV come to the rescue.
One of the most popular solutions is the AirScreen or AirPin app, which emulates different reception protocols, making the TV visible for iOS (AirPlay) and Android devices, and is installed directly from the remote via the built-in app store.
The process of installing third-party software:
- 📺 Go to the Google Play Store on your TV.
- 🔍 In the search, type the name of the application, for example, “AirScreen».
- ⬇️ Click “Install” and wait for the download to be completed.
- 🚀 Launch the application and press the “Start” button to activate the receiver.
Once the app is launched, your phone will see the TV as a native device, which is especially true for iPhone owners who want to display the image on Xiaomi TV, as native AirPlay support in MIUI TV can work unstable.
⚠️ Warning: Free versions of such apps often contain ads or have session time limits. For ongoing use, it is better to consider paid versions or open source alternatives.
Broadcast from specific applications (YouTube, Netflix, Movie Search)
Special attention should be paid to native broadcasting from player apps, services like YouTube, Netflix or HD Film Search have a built-in “Translate” button (a wave screen icon), which is considered the most energy-efficient method.
In this case, the phone does not transmit a video stream, but only sends a command to the TV: “Take a video on this link and show it.” The Xiaomi Mi TV 4A itself decodes the stream using its processor, which guarantees better quality and no jerks.
To take advantage of this function:
- Open the video in the application on your smartphone.
- Click on the broadcast icon in the corner of the player.
- Choose your Xiaomi TV 4A from the list.
- Control playback, pause and volume from your phone.
The main advantage is that you can turn off your phone screen or use other apps, and you can't stop watching on TV. This is the perfect scenario for long-term movie watching.
💡
Native streaming from apps (YouTube, Netflix) always gives better picture quality and less load on the phone’s battery than full screen duplication.
Solving problems and signal delays
Despite the ease of setting, users may experience audio and video out-of-sync or intermittent connection breaks, most often due to the router's Wi-Fi frequency range. The 2.4GHz standard is often overloaded with neighborhood networks and appliances.
For stable high-resolution image transfer (1080p and above), it is highly recommended to use the 5GHz band. Make sure that both the TV and smartphone are connected to a 5GHz network if your router supports dual-band operation.
If the problem persists, follow the following steps:
- 🔄 Reboot the router, TV and smartphone.
- 📶 Get closer to the Wi-Fi hotspot.
- 🛑 Close background apps on your phone that consume traffic.
- ⚙️ In the router settings, try changing the broadcast channel to a less loaded one.
It’s also worth checking for updates to the Android TV system on the TV, and manufacturers regularly release patches that improve the stability of wireless modules.
