With the modern multimedia capabilities of smart TVs, it is possible to turn a regular video viewing into a full-fledged theatrical experience. Xiaomi Mi TV 4S 43 is equipped with a powerful processor and supports HDR standards, making it an ideal screen for displaying content from mobile devices. However, many users face difficulties when trying to synchronize their smartphone and TV bar without knowing which data protocols are supported by the Android TV system.
There are several ways to organize the output of the image, from the built-in functions of the operating system to the use of third-party applications. The choice of method depends on whether you have a phone based on Android or iOS, as well as the type of content you plan to watch. In this article, we will discuss in detail all available options, including wired and wireless solutions, so you can enjoy photos and videos on the big screen without delay and loss of quality.
Before we get to the settings, we need to make sure that both devices are running correctly and are on the same LAN, which is a basic requirement for most wireless media technologies, and if we ignore this, the search for devices can go on forever or end up with a connection error.
Preparatory phase and network verification
The first step is to ensure a stable connection between gadgets.The Xiaomi Mi TV 4S 43 should be connected to the router, preferably via a LAN cable for maximum speed, although 5GHz Wi-Fi will be enough for streaming video in 4K. The smartphone also needs to be connected to the same network, otherwise the devices simply "will not see" each other in the list of available receivers.
Check the software version on your TV, as old firmware may contain bugs in the wireless modules. Go to Settings → About TV → System and check for updates. If the system offers to upgrade, be sure to agree, as this often fixes problems with Miracast and Chromecast protocols.
⚠️ Note: If your router supports Guest Network, don’t connect your devices to it. Guest mode client isolation prevents device-to-device communication within the same network, making it impossible to stream.
You should also pay attention to the date and time settings, so if the TV is down, security certificates may conflict, and some apps will refuse to transmit content, and set up automatic Internet time synchronization in the system settings.
☑️ Checking before connection
Use of the built-in Chromecast feature
The Android TV operating system installed on Xiaomi Mi TV 4S 43 has built-in support for Google Chromecast technology.This is one of the most convenient ways to stream content from apps such as YouTube, Netflix or the Chrome browser. You do not need to duplicate the entire screen of your smartphone, just send a specific video or browser tab.
To get started, open the app on your phone, find the broadcast icon (the rectangle with the waves in the corner) and select your TV from the list. The device should be identified as an Android TV or model name. Once connected, the image will appear on the screen, and the phone can be used as a remote control.
If the broadcast icon doesn’t appear, make sure that the smartphone has Google Play Services and Google Home, which is responsible for detecting and initially configuring devices in the Google ecosystem, and in some cases, you need to allow the app to access the local network in the phone’s privacy settings.
What to do if Chromecast doesn’t work?
Screen broadcast via Miracast (Wireless Display)
When you want to show a video from an app, but completely mirror the screen of a smartphone — for example, to show a presentation, photo gallery or game — Miracast technology is used. On Xiaomi TVs, this feature is often called “Wireless Display” or “Screen Mirroring.” Unlike Chromecast, it transmits real-time video stream from the entire interface of the phone.
To activate on the remote, click the signal source select button (Input or the arrow square icon) and select Wireless Display. The screen will have a wait for connection. On an Android smartphone, open the notification curtain and find Translation, Smart View (on Samsung) or Wireless Projector. On an iPhone, this feature is called Screen Replay and should also see the TV if AirPlay is installed.
Image quality when using Miracast is highly dependent on the power of the Wi-Fi signal. If there are jerks or desynchronization of the sound, try to approach the router or reduce the resolution of the output image in the phone settings.
AirPlay setup for iPhone and iPad owners
Apple owners can use the built-in AirPlay 2 protocol, which is supported by modern versions of the Xiaomi Mi TV 4S 43 firmware. This allows you to broadcast video, photos and even the entire screen of the iPhone without installing additional applications on the TV, while the transmission quality remains high and the delay is minimal.
Make sure your TV has AirPlay support on. Go to Settings → AirPlay and activate the function. You can set the access code there so that outsiders can’t connect to your TV. On your iPhone, open Control Point (swipe down from the top right corner) and click on the icon of two rectangles (Screen Replay).
If the TV doesn’t appear on the list, check to see if the router firewall blocks the ports required for Bonjour/Avahi (Apple Detection Protocols) to work.
💡
To reduce latency when playing with your iPhone on your TV via AirPlay, close the background apps on your smartphone and make sure the phone is connected to a 5GHz network, not 2.4GHz.
Wired connection via HDMI and adapters
Wireless technology is convenient, but not always stable. If you want maximum reliability and quality of the picture without compression, you better use a wired connection. This will require a special adapter, because you can not directly plug the phone into the HDMI port of the Xiaomi Mi TV 4S 43 TV.
Modern Android devices with USB Type-C ports need adapters that support MHL or DisplayPort Alt Mode. iPhones with Lightning connector need a Lightning to HDMI adapter, and new models with USB-C need an adapter that connects the adapter to the phone, and then connect it with an HDMI cable to the TV.
Once connected, switch the signal source on the TV to the appropriate HDMI 1 or HDMI 2 port. The image should appear automatically. The advantage of this method is that the phone does not consume a battery to transmit a video signal, and often even charges from the network (if the adapter has a power port).
| Type of connection | Image quality | Delay (Latency) | Battery consumption |
|---|---|---|---|
| Chromecast (Video) | High (up to 4K) | Low. | Minimum |
| Miracast (Screen) | Medium/High | Medium | High-pitched |
| AirPlay 2 | High. | Low. | Medium. |
| HDMI Cable | Maximum. | Absent. | Charging is possible. |
Third-party broadcast applications
If standard methods do not work or the functionality is not enough, applications from the Google Play store come to the rescue. Castify or Web Video Caster allows you to broadcast video files that are not supported natively, or broadcast browser content with advanced features.
Install the app on both your phone and your TV (if you have an Android TV version), or simply use the in-app device search feature on your smartphone. These programs often can “flip” video files directly to the TV’s media player, bypassing the phone’s screen, saving you charge.
Another option is to use the Xiaomi TV app (or Android TV Remote Control), which allows you not only to control the TV, but in some cases to send media files from the phone gallery to the big screen using the DLNA protocol.
⚠️ Note: When installing third-party applications from unknown sources (APK-Please be careful: download software only from the official Google Play Store to avoid the introduction of malware that can slow down the TV.
Solving Connection Problems and Errors
Even with the right setup, there can be failures. A common problem is that the Xiaomi Mi TV 4S 43 is visible on the list, but when connected, it says "Error" or "Unconnected." In this case, try restarting both devices completely by pulling the power cord out of the socket for 10-15 seconds, which will clear the memory buffer and reset network errors.
If there is an image but no sound, check the audio output settings in the app from which the broadcast is coming or in the TV sound settings (Settings → Sound → Audio Output). Sometimes switching the audio design mode from Original to Standard helps.
In cases where the broadcast is constantly interrupted, it is possible that the Wi-Fi channel is overloaded with neighboring networks. Go to the router settings and change the broadcast channel to a freer one (for example, 1, 6 or 11 for 2.4 GHz, or any free one for 5 GHz).
💡
90% of connection problems are solved by simply restarting the router and TV and checking that both devices are on the same subnet (the same is true). IP-lock-house).
