The modern multimedia capabilities of the Xiaomi Mi TV 4S 65 allow you to turn the living room into a real home theater, but this often requires streaming content from a mobile device. Users often face the need to bring photos, videos or the desktop of a smartphone to the big screen to share the experience with family or colleagues. In this article, we will discuss in detail all the current ways of connecting, from simple wireless methods to professional wired solutions.
The setup process can vary depending on your phone’s operating system, whether it’s Android or iOS. It’s important to understand that wireless connectivity requires a stable router, whereas cable provides maximum image quality without delay. The choice of method depends on your priorities: connection speed or maximum picture resolution.
Owners of the 4S 65 often note the presence of built-in Chromecast and support for the Mi Drop protocol, which makes life much easier. However, if you use an iPhone or a phone with a non-standard shell, additional applications or settings may be required. Below we will look at each method Step-by-step so you can choose the most suitable option for your situation.
Wireless screen projection via Wi-Fi (Miracast)
The most common and convenient way is to use Miracast technology, which is built into most modern Android smartphones. To get started, make sure that both the Xiaomi Mi TV 4S 65 and your phone are connected to the same Wi-Fi network. This is a critical condition, since when using a guest network or different frequencies (2.4 GHz and 5 GHz), devices may simply not see each other.
On the TV remote, find a button with the remote or application icon and go to the signal source selection menu. You need to select the option of Wireless Display or Wireless Display. Once this function is started, the TV will go into the connection standby mode, displaying the device name on the screen.
💡
For maximum picture stability in wireless projection, it is recommended to connect both devices to a 5GHz network if your router supports this range.
Now take your smartphone and lower the notification curtain. Find a feature that can be called differently depending on the brand: Broadcast, Smart View (Samsung), Projection (Xiaomi) or Screen Replay. After scanning the network, your Xiaomi TV should appear in the list. Click on it, and the image from the smartphone instantly appears on the 65-inch panel.
- 📱 On Xiaomi smartphones: Open the control center and click on “Translation».
- 📺 On Samsung: The feature is called “Smart View” in the notification curtain.
- 🍏 On iPhone: Use Screen Replay through Control Point (Cromecast needed).
- 🔌 Make sure that the “Wireless Display” app is running on TV».
It's worth noting that when you use Miracast, the image quality may be slightly inferior to the wired connection due to compression of the video stream, but for viewing photos, presentations or YouTube, this is quite enough. If you notice a desynchronization of sound and video, try rebooting the router.
Use of built-in Chromecast and Google Home
Xiaomi Mi TV 4S 65 is powered by Android TV, which means it has built-in support for Google Chromecast technology, which allows you to stream content directly from apps like YouTube, Netflix, Spotify or Google Chrome without duplicating the entire screen of your smartphone, a method that is more energy efficient for your phone battery.
To get started, make sure your smartphone has a Google Home app installed. It's necessary for initial setup and device management, although many apps can find a TV without one. Open the app and it will automatically detect your TV on the local network.
To start the broadcast, open a supported app (like YouTube) on your phone. At the top of the video or in the corner of the interface, a Cast icon (rectangle with waves in the corner) will appear. Click on it, select your Xiaomi Mi TV 4S from the list. The video will play on the TV, and the phone can be used as a remote control or switch to other tasks.
⚠️ Note: If the Chromecast icon doesn’t appear, check that the Google Home app has all the necessary permissions, and also make sure that the antivirus on the router does not block local device detection.
The advantage of this method is that the TV itself decodes the video stream, unloading the processor of the smartphone, you can receive calls or respond to messages without interrupting the playback of the movie on the big screen, the quality of the picture in this mode is often higher than with simple duplicate screen.
iPhone and iPad (AirPlay and third-party solutions)
Apple owners are less fortunate with native support, as the Xiaomi Mi TV 4S 65 does not have an AirPlay 2 built-in module in standard firmware (although new MIUI for TV updates may have this feature), but this does not mean that broadcast content is impossible. There are several proven ways to circumvent this limitation.
The first and most reliable option is to use third-party apps on the TV itself. Go to the Google Play Store on your TV and find the AirScreen or Receiver for AirPlay app. Once you install and launch this app, the TV will start emulating the AirPlay receiver, and your iPhone will see it as a native device.
Once you run the emulator on TV, open Control Point on your iPhone (swipe down from the top right corner or up from the bottom on older models). Click on the Repeat screen icon (two rectangles). The name given in the app on your TV will appear in the list of available devices. Click on it to connect.
- 🍎 Install AirScreen from the Play Market Store on TV.
- 📡 Launch the app on your TV and click “Start».
- 📱 On iPhone, select Screen Replay and find the device.
- 🎮 For games, use Game mode in AirScreen settings to reduce latency.
Alternatively, using intermediary apps like Cast to TV or Web Video Caster, which allow you to send video files or streaming links directly to your TV without using the standard AirPlay protocol, is especially useful if you want to watch videos from a Safari browser that doesn’t support standard streaming.
Wired connection via HDMI and USB-C
If wireless methods don’t provide the stability you need or you plan to play games with minimal latency, a wired connection is the best choice. For this, you will need a special USB-C to HDMI adapter or Lightning to HDMI for the iPhone, as well as a regular HDMI cable. Xiaomi Mi TV 4S 65 model comes with several HDMI ports, usually located on the back or side.
Connect the adapter to your smartphone, then connect it with an HDMI cable to your TV. Switch the TV signal source to the appropriate port (e.g. HDMI 1 or HDMI 2). Unlike Wi-Fi, you don't need to set up the network, the image is digitally transmitted without loss of quality or compression.
☑️ Checking before buying the cable
It's important to know that not all smartphones support image output via the charging port.The flagship models of Samsung (S and Note series), Huawei (P and Mate series), Xiaomi (flagships) and iPhone (starting with the Model 5) usually have this feature. Budget devices may not transmit video via USB, even with an adapter.
⚠️ Note: When connecting through HDMI The phone can run out quickly, as it powers the video output. It is recommended to use an adapter with an additional port for charging (PD), to simultaneously broadcast the image and charge the device.
This is ideal for high-resolution presentations or games where every millisecond of response is important, and the picture is clear, without the compression artifacts that are characteristic of wireless technology.
Broadcasting through the Mi Home app
Xiaomi’s ecosystem offers its own Mi Home app, which serves as a single control center for all smart devices. Although its main function is to manage a smart home, it also allows you to interact with your TV, especially if you want to stream media files stored in your phone’s memory.
To get started, install the app on your smartphone and make sure your Mi Account is authorized on both devices. Add a TV to the app if it doesn't already appear on the device list. This will create a bridge between your phone and TV, allowing you to send files directly.
Open a media file (photo or video) in the phone gallery or file manager. Click Share and select Mi TV or Cast. The file will open on the TV. This method is convenient because it does not require you to run additional apps on the TV itself, if they are already installed.
| Connection method | Image quality | Delay (Latency) | Difficulty setting up |
|---|---|---|---|
| Miracast (Wi-Fi) | High (Full HD/4K) | Medium | Low. |
| Chromecast | Very high (4K HDR) | Low (for video) | Very low. |
| HDMI Cable | Maximum (no compression) | Minimum | Medium (needs adapter) |
| AirPlay (via the app) | High. | Medium | Medium |
Using the Mi Home ecosystem is especially relevant if you want to create a smart home scenario, such as “Cinema,” where the lights automatically dim when you start a stream, but for simply watching YouTube videos, this method can be redundant compared to Chromecast.
Solving and eliminating connection errors
Even if you follow all the instructions, you can have technical difficulties. One of the most common problems is that the TV can't see the phone. 90% of the time, it's because the devices are on different subnets or because the client isolation on the router is turned on. Try rebooting the router and reconnecting both devices.
Another common mistake is lag and interrupting the picture when wirelessly connected, which often happens if the Wi-Fi channel is overloaded with neighbor networks, go to the router settings and change the broadcast channel to a freer one, or switch the TV to a 5 GHz band that is less crowded.
What if there is no sound when connecting via HDMI?
If the problem is that the picture is not full screen or stretched, check the aspect ratio settings on the TV. Press the menu button on the remote (usually a three-dot or gear button) and find the screen format or Aspect Ratio. Select the screen size or 16:9 mode to remove the black bars.
- 🔄 Reboot the router, phone and TV.
- 📡 Check if the “Guest Network” mode on Wi-Fi is enabled.
- 📺 Update the TV firmware through the settings menu.
- 🔌 Try another port. HDMI cable.
In rare cases, the problem may be in an outdated version of the Google Play Services app or Android TV system components. Go to the TV settings, App section, find the relevant services and check for updates.
💡
The stability of a wireless connection depends on the quality of the router and the distance to it; with constant problems, switching to an HDMI cable is the most reliable solution.
