Modern multimedia content requires large screens and high-quality sound, making displaying images from a smartphone to a TV display one of the most popular features. Owners of Xiaomi Mi TV 4S often face the desire to showcase photos, videos or run a mobile game on a large diagonal, but the process of setting up can seem confusing due to the features of the Android TV shell. Unlike simple “smart” consoles, this model has built-in wireless communication modules, but requires the right configuration for stable operation.
There are several proven ways to broadcast the screen, each of which depends on the operating system of your mobile device and the version of the TV firmware. We will look at the standard Mi TV system, the use of Google Cast protocols and third-party solutions that guarantee minimal signal latency. It is important to understand that for successful connection both devices must be on a single local network, which is a basic but critical condition.
In this article, we will take a detailed look at the algorithms for different scenarios so you can enjoy content without unnecessary wires and complex settings. Whether you use a flagship smartphone or a budget model, the basic principles of video streaming remain similar, differing only in the names of items on the menu.
Device Preparation and Network Environment
Before you start setting up, make sure your Xiaomi Mi TV 4S is connected to the internet and works correctly. Go to the TV settings menu and select the Network section to check the connection status. If you use a wired connection, make sure that the Ethernet cable is securely inserted into the connector, as Wi-Fi bandwidth may not be enough to transmit high-resolution (4K) video.
A mobile device must be connected to the same Wi-Fi network as a TV, a fundamental requirement of the DLNA and Chromecast protocols on which most transmission methods are based. If your router supports dual-band, it is better to use a 5 GHz network to ensure high data speeds and reduce latency.
⚠️ Note: Use of guest Wi-Fi or mobile data (4G/5G) on the phone with a TV connected to Wi-Fi will make broadcasting impossible, since the devices will be in different subnets.
💡
For maximum stability when viewing 4K-Video recommends connecting the TV with an Ethernet cable and leaving the phone on the 5 GHz Wi-Fi network.
Check that the device detection feature is enabled on the TV. In some versions of MIUI for TV firmware, this option can be hidden in the depth of the menu or disabled by default for security purposes. Go to Settings → Network and Internet → Network environment and make sure that the switch is active.
The Wireless Display (Miracast)
The most versatile way to install no additional apps on your TV is to use Miracast technology, which in the Xiaomi ecosystem is often called Wireless Display, which allows you to completely duplicate the smartphone screen, including the interface, notifications and system sounds.
To run on a Xiaomi 4S TV, you need to find the "Wireless Display" or "Wireless Monitor" app in the installed program list or in the "Applications" folder. After launch, the screen will wait for connection. On an Android smartphone, the process may differ depending on the shell manufacturer.
- 📱 For Samsung: Lower the notification curtain and select Smart View".
- 📱 For Xiaomi/Redmi: Go to the Management" → "Broadcasting".
- 📱 Huawei: Projection feature in the control center.
- 📱 For other Android: look for “Translation”, “Cast” or “Wireless Projector".
Once you find a TV, click on the name on the list, and you may see a request for confirmation of connection on the TV screen, which you need to coordinate with the remote, and the quality of the image depends on the power of the router and the distance to it.
Using Google Chromecast technology
Xiaomi Mi TV 4S is based on the Android TV operating system, which means built-in support for Google Cast technology. This is a more advanced method compared to Miracast, since it allows you not only to duplicate the screen, but also to transfer a command to play the content directly by the TV, saving battery power of the smartphone.
To use this method, make sure that the app you want to stream the video from (e.g. YouTube, Netflix, VK Video) supports Cast. In the application interface, find the rectangle icon with waves in the corner.
If the TV is not displayed, check that the mobile device has installed and updated the Google Home app, which is necessary for the initial configuration and management of Chromecast devices, and make sure that you use the same Google account on your phone and TV on the YouTube app, although this is not a strict requirement for basic work.
Why is Chromecast better than Miracast?
Broadcast from iPhone and iPad (AirPlay)
Owners of Apple devices should not despair, as modern firmware Xiaomi Mi TV 4S often have built-in support for the AirPlay 2 protocol. However, if your version of the software this feature is missing or unstable, the best solution is to install a third-party application.
You should install AirScreen or AirPin from the Google Play Store on the TV itself. Once installed, run the app on your TV and follow the instructions on the screen. It emulates the AirPlay receiver, making the TV visible to your iPhone.
On your iPhone, open Control Point (swipe down from the top right corner or bottom up on older models) and click Screen Replay. Select your TV from the list. Image will appear instantly.
| Parameter | Miracast | Google Cast | AirPlay (via the app) |
|---|---|---|---|
| Quality. | Up to 1080p. | Up to 4K HDR | Up to 1080p/4K |
| Delay. | Tall. | Low. | Medium |
| Battery consumption | High-pitched | Low. | Medium. |
| Sound. | Synchronization can be lame | Great. | Good. |
Specialized applications for broadcasting
If the standard methods don’t work or require advanced functionality, such as streaming local files of certain formats, it’s worth turning to specialized applications. One of the most popular solutions for the Xiaomi ecosystem is the Mi Remote app (although it’s more for management) and LocalCast.
LocalCast allows you to stream video files, photos and music directly from your phone’s memory or from Google Drive (Dropbox) to your TV, and automatically selects the best codec to play on Xiaomi 4S.
Another powerful tool is Web Video Caster, which is unique in that it allows you to pull video streams from sites that don't have official Cast support, so you open a site inside the app, it finds a video file, and it sends a link to the TV to play.
☑️ Checking before installing applications
When installing third-party applications, pay attention to the permissions they request. They need access to the local network and file system to work properly.
Connection problems and their solution
The most common problem is that the TV just can't see the phone or vice versa, and 90 percent of the time it's connected to the router settings, and many of today's routers have AP Customer Isolation, which prevents devices on the same Wi-Fi network from sharing data with each other.
To solve this problem, go to the router settings (usually through 192.168.0.1 or 192.168.1.1 in the browser). Find the Wireless Settings section and make sure that the AP Isolation tick is removed. Change the Wi-Fi channel to a less loaded one (1, 6 or 11) can also help.
⚠️ Warning: Antivirus programs on a smartphone or firewalls on a router can block ports used for protocols DLNA Try temporarily disabling the security for the check.
If the image is broadcasting but with delay or artifacts, try lowering the output resolution in your phone settings or bringing your smartphone closer to the router.
💡
The stability of the broadcast depends on the quality of the Wi-Fi signal and the lack of isolation of customers on the router, not on the power of the TV.
Broadcasting via cable (wired connection)
For situations where wireless communication is not possible or maximum quality is required without compression, you can use a cable connection. Xiaomi Mi TV 4S is equipped with HDMI ports, which allows you to connect the smartphone via an adapter.
You'll need a USB-C to HDMI adapter (for modern Android) or Lightning to HDMI (for iPhone). Connect the adapter to your phone, and an HDMI cable connects the adapter and the TV. Switch the signal source to the TV with the Input button on the remote to the appropriate HDMI port.
This method ensures no delays, which is critical for gaming, but it is worth considering that not all smartphones support video output through video. USB The video output support technology is often called the port. MHL SlimPort.
