Xiaomi’s modern smartphones have powerful screens and processors, but sometimes 6.7-inch diagonals are not enough to view content. You need to stream videos, photos, or even desktops to a large home theater display. Fortunately, the MIUI and HyperOS ecosystem offers many built-in tools to do this without buying additional hardware.
There are several basic signaling protocols, each with its own hardware and features. Wireless methods like Miracast and Google Cast can eliminate unnecessary wires to ensure decent picture quality. However, for games with minimal latency or watching video in 4K HDR, a more stable wired connection may be required.
In this article, we will take a look at all the available connectivity options, from standard system functions to third-party applications, how to set up Wi-Fi broadcasts, which cables are best used for wired connections, and what to do if the TV can’t see the smartphone. Understanding the technical nuances will help to avoid dissynchronizing sound and image.
Wireless broadcasting through the built-in function "Translation"
The easiest and most popular way to display an image on a TV screen is to use a native feature of the Android system, which in Xiaomi shells is called Translation. This technology is based on the Miracast standard, which means that you can transfer video stream directly from device to device without the need for a router, if the TV supports the Wi-Fi Direct function.
To get started, make sure your Smart TV and Xiaomi smartphone are connected to the same Wi-Fi network. If the router is dual-band, it is advisable to use a 5 GHz network, as it provides higher bandwidth, which is critical for high-resolution video transmission. On the TV remote, you must choose the source of the signal "Screen Mirroring", "Translation" or similar, depending on the Samsung, LG or Sony brand.
- 📱 Open the control menu on your smartphone swipe down and find the icon “Translation».
- 📺 Enable the device search mode on the TV through the network settings menu.
- 🔗 Select the TV that appears in the list on the smartphone screen.
- ✅ Confirm the connection if a connection request appears on the TV screen.
Once paired successfully, the image from the phone will appear on the big screen. It is worth noting that using this method, the smartphone can significantly heat up, as the process of encoding the video stream falls on the shoulders of the processor. The Translation function in Xiaomi broadcasts the entire screen of the smartphone, including notifications and system sounds, so it is better to turn on the Do Not Disturb mode before you start watching.
Using Google Chromecast technology built-in
Unlike mirror display, Chromecast (or Google Cast) allows you to stream content directly from apps, which means that the video file is downloaded by the TV directly from the Internet, and the smartphone acts only as a remote control, which significantly saves battery power and reduces the load on the phone processor.
Most modern Smart TVs have built-in Chromecast support. To check this out, open a YouTube or Netflix app on a Xiaomi smartphone. The top right corner of the player should have a distinctive wave rectangle icon. If you click on it, your TV is available in the list, then the technology is working correctly.
It's important to understand the difference between Miracast and Cast. In the first case, the phone encodes the image and sends it in a stream, which can lead to lags with weak Wi-Fi. In the second case, the phone simply tells the TV to "please play this video on this link." Android TV and many Tizen or WebOS firmwares are great at decoding heavy formats on their own.
What to do if the Chromecast icon doesn’t appear?
Wired connection via USB Type-C and HDMI
For users who want maximum signal stability and no delays (input lag), wired connection is the best solution. However, not all Xiaomi smartphones support image output through the charging port. USB 3.1 with DisplayPort Alt Mode or Thunderbolt.
Flagship models such as the Xiaomi 13 Ultra series, Xiaomi 14 or the old Mi 10 Pro are usually equipped with a USB 3.2 port that allows you to transmit a video signal. Budget and medium-sized models (Redmi Note series, Poco M/X) most often have a USB 2.0 port that physically cannot transmit video stream, limited only to charging and data transfer.
You'll need a USB Type-C to HDMI adapter to connect, and you won't be able to just insert a Type-C cable into a Type-C cable, because you rarely see USB-C inputs with a video input on TVs, and the adapter converts the digital signal into a format that the TV can understand.
☑️ Compatibility check for HDMI
If your smartphone supports video output, the cable will automatically show the image on TV. In Settings → Connected devices → USB, you can select the mode of operation. The advantage of this method is that the phone charges simultaneously, and the picture quality corresponds to the native resolution of the screen without compression.
💡
When buying an adapter, make sure it supports a minimum of 1080p resolution at 60Hz. Cheap cables are often limited to 30Hz, making the cursor movement or interface animation jiggley and unpleasant for the eyes.
Broadcasting through Smart TV apps
If the built-in features are not working properly or the TV is not a Smart TV, specialized applications come to the rescue, and the leader in this niche is the Google Home app, which allows you to manage media files and broadcast the screen to devices with Chromecast support.
For TVs without Android TV, applications from manufacturers are often used, for example, LG TV Plus or Samsung SmartView. Also, the universal solution is the Xiaomi Mi Remote application, which can control the IR port, but third-party solutions like Web Video Caster or BubbleUPnP are better suited for video broadcasting.
The setup process usually involves installing the app on your smartphone and, in some cases, on your TV (if you have an app store), and then you scan the network and you ask them to select the target device. TV-Android-box.
⚠️ Note: When using third-party free broadcast apps, be prepared for the presence of advertising. Some programs may compulsively offer paid subscriptions to remove ads or access features 4K.
Comparison of Connection Methods and Their Characteristics
To choose the best way, you need to consider the purpose of use. For watching movies, the quality of the picture and the absence of compression artifacts are more important, and for presentations or demonstrations of the interface, the stability of the connection.
| Method | Delay (Latency) | Image quality | Battery consumption | Requirements |
|---|---|---|---|---|
| Miracast (Translation) | Medium (100-300 ms) | Good (depends on Wi-Fi) | High-pitched | Wi-Fi Direct, TV Support |
| Chromecast | Low (management) | Excellent (native TV) | Low. | Internet, Annex |
| HDMI (Adapter) | Minimum | No loss. | Charging is coming. | USB 3.1+, Adapter |
| DLNA (Media) | No (files only) | Excellent. | Medium. | Local area network |
As you can see from the table, wired connections win in all technical aspects, but lose in usability. Wireless methods require careful network configuration. If the router is old or overloaded by neighbors, even the best Xiaomi smartphone will show jerks when broadcasting.
💡
For games and text, use only HDMI cable. Chromecast is ideal for watching videos from online cinemas. Miracast is ideal for quickly showing photos.
Solution: Problems and their elimination
Despite the technology, users often experience a TV that doesn't see the phone or the connection is constantly broken, most often the problem lies in the router's security settings. Many providers default to isolating customers. AP (AP Isolation, which prevents devices on the same network from seeing each other.
Another common reason is the use of different frequency bands: If the phone is connected to 5 GHz and the TV (especially the old one) only runs at 2.4 GHz, they may not detect each other for direct connection, although the router will transmit data, in which case setting up a single network name (SSID) for both bands helps.
- 🔄 Reboot your router and both devices – it solves 80% of network problems.
- 🛡️ Turn it off. VPN on a smartphone, as it changes the virtual location.
- 📶 Check if the traffic saving mode in the browser or system is enabled.
- 📲 Update your YouTube or Netflix app to the latest version.
⚠️ Note: If the sound is broadcasting over Wi-Fi and the images are not (black screen), the content is most likely protected. DRM-protection (HDCP), The method of transmission chosen does not support the transfer of protected content. HDMI cable.
In conclusion, Xiaomi’s ecosystem provides flexible tools for interacting with the outer periphery. Whether you’re using the latest flagship or budget Redmi, you’ll be able to find the right way to display your image, and the key is to properly evaluate your TV’s capabilities and the quality of your home network.
