With modern multimedia capabilities, any smartphone can be turned into a powerful control center for the home theater. Xiaomi device owners often face the need to stream content to the big screen to enjoy high-resolution movies with the whole family. The company’s ecosystem provides several efficient synchronization methods, each with its own unique advantages and use cases.
The best way to choose depends on your TV model, the version of the MIUI or HyperOS operating system, and the availability of a wired connection. In this article, we will discuss in detail wireless protocols, cable connections and specialized streaming applications, learn how to eliminate common connection problems and achieve stable video streaming.
It is important to understand that for quality image transfer, the stability of the Wi-Fi network plays a critical role. Before setting up, make sure that both devices are on the same LAN or have serviceable ports for a physical connection. We will look at both standard Android features and proprietary developments of Xiaomi engineers.
Wireless streaming via Miracast and built-in features
The most common and convenient way is to use Miracast technology, which is built directly into the MIUI shell. This feature allows you to duplicate the smartphone screen on the TV without the use of additional accessories or complex router configuration.
To activate, you need to lower the notification curtain and find the "Translation" or "Cast" icon. In some versions of the firmware, this feature may be hidden in the quick button editing menu. Once turned on, you will start searching for available displays within the range of the signal.
- 📺 Open the “Translation” menu in the notification curtain of your smartphone.
- 📡 Make sure your TV supports Miracast or has a built-in Wi-Fi module.
- 🔗 Select your TV name from the list of available devices.
- ✅ Confirm the connection on the TV screen if you need permission.
It's worth noting that this is a real-time image that can create minimal latency. It's not critical for watching movies, but for dynamic games, the delay can be noticeable. Miracast's protocol broadcasts the image from the screen, not the video stream, which increases the load on the phone's processor.
Using Google Chromecast built-in technology
Unlike simple screen duplication, Chromecast technology allows you to send content directly to the TV, freeing up your smartphone for other tasks. Many modern Xiaomi Mi TVs and Android TVs have built-in support for this standard.
When you run a video on a YouTube, Netflix or Kinopoisk app, the player interface has a characteristic wave rectangle icon, and you tap it to select the target device, so the phone acts as a remote control, and the TV takes over the buffering and decoding of the video.
The advantage of this method is that you can use your smartphone while watching a movie, you can answer calls, check messages, or play games without interrupting the playback on the big screen, and the quality of the picture is often higher, because the TV itself decodes the stream.
⚠️ Note: Both devices must be connected to the same Wi-Fi network to work with Chromecast. If the router has a band-sharing (2.4 GHz and 5 GHz), make sure the phone and TV are in the same frequency segment.
Connection via HDMI cable and adapters
For users who require maximum image quality and no delays, the optimal solution is wired connection. HDMI The type of adapter depends on the version. USB plug-in.
Flagship models with USB Type-C 3.0 and higher support video transmission via the DisplayPort Alt Mode protocol. Owners of such devices can purchase a simple USB-C to HDMI cable. Budget models with USB 2.0 require an active adapter with support for MHL or DLNA, which often needs additional power.
The connection process is as simple as possible and does not require complex software configuration. After connecting the cable to the phone and TV, you need to switch the signal source to the TV to the appropriate HDMI 1 or HDMI 2 mode.
☑️ Checking the compatibility of the cable
If the image does not appear automatically, check the resolution settings in the developer menu or in standard screen settings. The cable connection guarantees a 4K signal at 60Hz resolution if both devices support it.
Comparison of connection methods: Characteristics table
To make it easier for you to choose the right way, we have prepared a comparative table of the main characteristics of various connection methods: Pay attention to the network requirements and the effect on the battery charge of the device.
| Method | Image quality | Delay (Latency) | Battery consumption |
|---|---|---|---|
| Miracast | High (up to 1080p/4K) | Medium (notable in games) | High-pitched |
| Chromecast | Maximum (depending on TV) | Low (for management) | Low. |
| HDMI cable | Maximum (no compression) | Absent. | Charging the phone |
| DLNA | High (media only) | Low. | Medium. |
As you can see from the table, cable is best for gaming, and Chromecast is best for watching movies from online services. Wireless screen duplication is universal, but requires a charged battery.
💡
Cable connection is the only way to get an image without compression and delay, which is critical for gamers and professionals.
Broadcasting through applications and DLNA
In addition to system features, there are many third-party applications that extend synchronization capabilities. The DLNA protocol allows you to transfer media files (photos, videos, music) from your phone to your TV without duplicating the entire screen, which is convenient when you need to show a specific video from the gallery.
A popular solution is the Mi Remote app or the built-in Xiaomi Video video player, which can find devices on the network, and you can also use universal media servers such as BubbleUPnP or VLC for Android, which scan the local network and offer a list of available renderers.
You don't have to duplicate the system interface to use DLNA, you pick a file in the gallery, you click on the Translate button, you pick the TV, the video starts playing on the big screen, and the phone can be locked or used for other tasks.
⚠️ Attention: When in use DLNA If the file codec is not supported by the TV, playback may not start or go without sound.
What to do if the TV can’t see the phone?
Troubleshooting and troubleshooting
Even when set up correctly, there can be situations where the connection is unstable or non-existent. Often the problem lies in MIUI energy saving settings, which aggressively restrict background processes. If the broadcast stops, add the casting app to the battery exceptions.
Another common reason is an outdated version of Wi-Fi drivers or system software. Check for updates in the Settings menu → About phone → System update. Sometimes a simple restart of both devices helps, which clears the cache of network services.
If you're using cable and you don't have images, try lowering the output resolution. Some older TVs can't process 4K HDR signals from modern smartphones. You can change the settings in the engineering menu or through special display tuning apps.
- 🔄 Reboot your router, phone, and TV to reset network settings.
- 🛡️ Turn it off. VPN on a smartphone, as it can block local detection.
- 🔌 When using an adapter, make sure it gets enough power.
- 📶 Get closer to the router if the Wi-Fi signal is weak.
In difficult cases, when software methods don't help, it may be necessary to reset the phone's network settings to factory settings.This will remove stored Wi-Fi passwords, but often resolves conflict issues. IP-address.
💡
For stable 4K video transfer, use a router that supports Wi-Fi 5 (ac) or Wi-Fi 6 (ax) and connect devices to the 5 GHz band.
