Xiaomi’s modern smartphones have powerful screens and multimedia capabilities, but sometimes 6 inches diagonal isn’t enough to comfortably watch movies or present photos. Fortunately, wireless image technology allows instantaneously streaming content from your phone to a large TV screen, eliminating the need to search for cables and adapters. This is especially convenient when you need to show colleagues a presentation or launch a film from an online cinema in a home theater.
The connection process can vary depending on your TV model and the MIUI or HyperOS shell version. There are several major protocols, such as Miracast, DLNA and Google proprietary solutions, that are built into the Android operating system. Understanding the differences between these technologies will help you choose the most stable method for your particular situation and avoid image delays.
In this article, we will take a look at all the available ways to sync devices, from standard system functions to third-party applications. You will learn how to configure high-resolution audio and video transmission, what router settings can affect streaming quality, and what to do if the TV does not see the smartphone. Follow the instructions to enjoy content on the big screen without unnecessary hassle.
Wireless Image Transmission Technologies: What’s the Difference
Before you start setting up, it’s important to understand what technologies are behind the Translation feature. Most people are familiar with the term Miracast, which is the wireless media standard. This technology allows you to duplicate a smartphone screen on a TV in real time, creating a direct connection between devices without the help of a router, although the presence of Wi-Fi modules in both gadgets is mandatory.
Another popular standard is Google's Chromecast built-in. Unlike Miracast, which simply mirrors the screen, Chromecast lets you stream content directly from the app on your TV, using the phone as a remote control, freeing up the smartphone for other tasks and allowing for more stable high-resolution video playback, as data flows directly from the Internet to the TV.
Also worth mentioning is the DLNA protocol, which is more often used to transfer media files (photos, videos, music) from the phone’s memory to TV, rather than duplicate the system interface. Many modern Smart TVs support all these standards simultaneously, but on the menu they can be called differently: Screen Share, Wireless Display, Smart View or simply “Device Connection”.
- 📡 Miracast is perfect for full screen and game duplication.
- 📺 Chromecast is the best choice for watching YouTube and Netflix videos.
- 🎵 DLNA — Suitable for playing files from the gallery without downloading to a flash drive.
⚠️ Note: For Miracast and Chromecast to work, both devices must be on the same local Wi-Fi network unless Direct Connection is used).
The choice of technology depends on your goals. If you need to show an app interface that is not on your TV or run a mobile game, use Miracast. For viewing movies, the built-in features of video services through Chromecast are better suited, which provides a better picture and less battery load on your smartphone.
Preparing devices for synchronization
Successfully connecting a Xiaomi phone to a TV starts with properly preparing both devices.The first step is to make sure your Smart TV supports wireless display. On most current models from Samsung, LG, Sony and Android TV, this feature is built-in by default, but on some budget models, you may need to activate in the network settings menu.
On a Xiaomi smartphone, there are also a number of pre-actions to take: Make sure the Wi-Fi module is on and the phone is connected to the same network as the TV. If you use a guest Wi-Fi network or customer isolation on the router, the devices may not be able to "see" each other, so it's best to use the main home network.
Check the software’s relevance. Xiaomi owners should go to Settings → About Phone and make sure the latest version of MIUI or HyperOS is installed. The TV also recommends updating the firmware through the support menu or system, as older versions of the software may contain bugs in the wireless protocols.
☑️ Preparation for connection
The aggressive optimization of the battery in the shell of Xiaomi sometimes blocks the background processes necessary for stable connection. Before the broadcast, it is recommended to temporarily turn off the energy saving mode so that the system does not interrupt the connection when the screen goes out.
Using the built-in Translation feature in Xiaomi
The easiest and fastest way to connect a Xiaomi phone to a TV is to use an integrated system function, which in different versions of the shell can be called “Translation”, “Wireless Monitor” or “Cast” – this method is based on the Miracast standard and does not require the installation of additional software.
To activate the function, open the notification curtain control center and find the Broadcast icon. If the icon is not in quick access, click on a pencil or three dots in the corner of the curtain to edit the list of switches, and add Translation to the panel. Once turned on, you will start searching for available devices within Wi-Fi range.
On the TV, you need to run an app to receive the signal. On Android TV, this is often called "Translation" or "Screen Mirroring", on Samsung, "Smart View", and on LG, "Screen Share", and once the TV goes into standby mode, its name will appear on the list on the smartphone.
Path to function: Settings → Connection and sharing → BroadcastOnce you select a TV from the list, you may have a request for confirmation of connection on your smartphone screen. Accept it, and the image of the Xiaomi desktop will appear on your TV. The quality of the picture and the presence of delays will depend on the power of the router and the distance between the devices.
- 📱 Use the notification curtain or connection settings to activate.
- 📺 You need to start the signal reception application (Miracast) on TV).
- 🔒 At the first connection, confirmation on the TV remote may be required.
⚠️ Note: When using the built-in broadcast, the smartphone screen should be turned on. If the screen goes out, the broadcast may be interrupted if special settings are not configured in the "Developers" section».
In some cases, especially in older versions of MIUI, the feature may be called Wireless Monitor, and the way it works is the same: find the device and connect. If the TV isn't there, try bringing the phone closer to the router or restarting the Wi-Fi module on both devices.
Broadcasting through the Google Home app
If the built-in Xiaomi feature is unstable or your TV is running on Android TV / Google TV, the official Google Home app is a great solution.This is a versatile tool for managing a smart home that also does a great job of screen duplication (Chromecast built-in).
Download and install Google Home from the Play Market store if it hasn't already been installed. Sign in to your Google account. The app will automatically scan the network and find compatible devices, including TVs, speakers and set-top boxes. Find your TV in the device list and click on its icon.
In the TV control menu that opens, click the Cast my screen button, and the system will warn you that the sound and image from your smartphone will be broadcast on TV. Confirm the action, and in a few seconds the phone screen will appear on a large display.
The advantage of the method through Google Home is a more stable connection and support for sound management. In addition, this method often provides lower latency, which is critical when demonstrating dynamic content.
Video streaming from YouTube and other apps
To view video content from online cinemas (YouTube, Netflix, IVI, Okko) you do not need to duplicate the entire screen of a smartphone. Most popular applications support Chromecast or DIAL technology, which allows you to run video directly on the TV, using the phone as a remote.
Open an app like YouTube on a Xiaomi smartphone. Make sure the phone is connected to the same Wi-Fi network as the Smart TV. In the upper right corner of the video or in the app interface, find the Broadcast icon (a rectangle with waves in the corner). Click on it and select your TV from the list.
The video will run on the TV, and the smartphone screen will appear control panel with buttons Play/Pause, rewind and adjust volume, the main advantage of this method is that you can turn down the YouTube app, respond to a message or even turn off the phone screen — playback on the TV will not interrupt.
| Parameter | Screen Duplication (Miracast) | Video broadcast (Chromecast/DIAL) |
|---|---|---|
| Battery load | High (screen is constantly on fire) | Low (screen can be extinguished) |
| Image quality | Depends on the power of the phone. | Maximum (depending on TV and network) |
| Multitasking | Impossible (all seen) | Possible (you can use the phone) |
| Delay. | Present. | Absent. |
This method is the most energy efficient and convenient for long-term movie watching, and it also avoids overheating of the smartphone, since the process of decoding video takes over the TV, not the mobile processor.
Third-party applications and solutions for old TVs
Owners of TVs without Smart TV Or the old operating system may be faced with a lack of support for Miracast or Chromecast, in which case third-party applications come to the rescue, which are installed on both the smartphone and (if possible) on the TV, or use the device. DLNA-server.
One popular solution is the Web Video Caster or LocalCast app, which allows you to stream video files from your phone's memory or browser links to your TV. If the TV doesn't have an OS but supports DLNA, you can use the Xiaomi-built player or Mi Video app by selecting the Translation option (DLNA) and finding a renderer on the network.
For older models that don’t have any smart functionality, the only wireless solution is to buy an external adapter like Google Chromecast, Mi, and other devices. TV Stick or any analogue with HDMI-These devices are inserted into the port. HDMI TV, after which it becomes a full Android TV, Supports all of the above-described connection methods.
What to do if the TV does not support Wi-Fi?
Using third-party software often circumvents the manufacturer's limitations by adding support for codecs or file formats that the TV's built-in player cannot read, but the stability of the connection depends entirely on the quality of the application's implementation.
The solution: problems and their elimination
Despite the simplicity of the technology, users often face typical problems: the TV can not see the phone, the image twitches or no sound. Most often the reason lies in network settings. Make sure that both devices are connected to the same frequency (for example, 2.4 GHz or 5 GHz), although modern routers must correctly handle traffic between different bands of the same network.
If the connection is permanently broken, try restarting the router. A crowded Wi-Fi channel or a large number of connected devices can cause interference, and check if the router has an AP Isolation mode that prevents devices on the network from communicating with each other.
If you have a sound problem, check the volume settings on both devices. Sometimes the sound stays on the phone even if the picture is on TV. In the broadcast settings (notification curtain) there may be an audio output switch. Some apps (such as Netflix) block the output of sound through Miracast due to DRM restrictions, requiring the use of Chromecast.
💡
If the broadcast is slowing down, try lowering the screen resolution in your phone’s settings or turning off Bluetooth on your smartphone, as it can cause interference in the 2.4GHz range.
⚠️ Warning: Antiviruses and firewalls on the router or in the client app on the phone can block ports needed to run Miracast. Try temporarily disabling protection to check.
If nothing works, reset your network settings on your TV and smartphone. Remove the stored Wi-Fi network on both devices and connect again. In rare cases, the problem may be incompatibility of protocol versions, and then the only way out is to use a physical HDMI cable with a USB-C to HDMI adapter.
