Modern smartphones have powerful screens and processors, but high-quality content or presentations often require a large diagonal. Owners of the Xiaomi ecosystem have a unique advantage, as the MIUI software and Android TV operating system installed on the brand’s TVs are deeply integrated, allowing you to set up a wireless connection in seconds without buying additional cables or adapters.
The mirroring process, which is technically called Miracast, is built into the basic functionality of most modern devices. You don't have to be an expert in networking technology to run a broadcast. However, there are many nuances that depend on the version of the operating system and the particular TV model that can affect connection stability and picture quality.
In this article, we will take a look at all the ways you can connect, from the standard system to the advanced methods for users who need minimal latency, and look at why sometimes the TV can’t see the phone, and how to solve the problem of desynchronizing sound and video.
Basic requirements for wireless connection
Before you start setting up, you need to make sure that both devices are ready to communicate. A fundamental condition for most media protocols to work is that the smartphone and TV are on the same local network, which means that both gadgets must be connected to the same Wi-Fi router.
If your router supports dual-band (2.4 GHz and 5 GHz), it is highly recommended to use a 5 GHz frequency.It provides higher bandwidth, which is critical for transmitting a video stream in 1080p or 4K resolution without compression artifacts and delays.
⚠️ Note: If your router gives away two different networks with the same name (SSID) For different frequencies, make sure that the phone and TV are connected to one of them, otherwise the devices may not “see” each other in the list of available frequencies.
Also worth checking is the software’s relevance. On your TV, go to Settings → About TV → System Update, and on your phone to Settings → About Phone → MIUI version. Outdated Wi-Fi drivers often cause the Translation feature to work unstable.
Use of the built-in Translation function in MIUI
The easiest and fastest way to do this, which doesn't require you to install any additional software, is to use a system utility, which can be called "Translation" or "Wireless Monitor" or "Cast" in the MIUI shell, and can be found through the control panel or in the connection settings.
To activate the function, lower the notification curtain and find the corresponding icon. If it is not in the visible part, click on the edit button (usually a pencil icon or three dots) and drag the widget to the desktop of the panel.
☑️ Pre-launch checks
When the TV appears on the list, click on it. The TV screen may pop up a request for confirmation of connection, which must be accepted by the remote control, then the image from the phone is completely copied to the big screen. If you want to broadcast only a specific application (for example, YouTube), and not the entire screen, this method can be redundant, and better use the built-in functions of the applications themselves.
💡
To reduce the delay in games, turn on the Game mode on the TV or turn off all post-processing images in the TV picture settings.
Broadcasting via Mi Remote and Chromecast
An alternative and often more stable method is to use Google Chromecast technology, which is built into most Xiaomi TVs with Android TV operating system.
Unlike Miracast, which broadcasts the entire screen, Chromecast allows you to transfer content directly from the app to the TV, using the phone as a remote control, which frees up the resources of the smartphone and allows you to continue using messengers or answering calls without interrupting the playback of video on the large screen.
To start the broadcast, open the app that supports this feature (YouTube, Netflix, Chrome browser). Find the broadcast icon (rectangle with waves in the corner) and select your Xiaomi Mi TV. The system will automatically identify the device and establish a connection.
⚠️ Note: When using Chromecast via Chrome browser, the picture quality may be lower than with direct mirror display of the screen, since the stream is first processed by the browser.
You can use your phone as a touchpad to control playback, and swipes on your smartphone screen allow you to change the volume or timeline of a video, which is especially useful when the remote control of the TV is lost or far away.
Third-party applications for advanced broadcasting
Staff tools don’t always work perfectly, especially if you need to stream a screen from a device that doesn’t support standard protocols, or if you want to stream sound from an application that blocks screen recording, in which case third-party solutions like AirScreen, ApowerMirror or Web Video Caster come to the rescue.
The AirScreen app turns your Xiaomi TV into a receiver for AirPlay (for iPhone owners) and DLNA. Once installed on your TV through the Google Play Store, launch the app and follow the instructions on the screen. It will create a virtual device that will be visible to your smartphone.
For users who are interested in maximum performance and minimal latency, the method of connecting via the Internet may be suitable. USB-cable-debugging ADB, But it requires you to install drivers on your PC and have root rights or special permissions on your phone.
| Method | Delay (MS) | Quality. | Difficulty |
|---|---|---|---|
| Miracast (Translation) | Low (50-100) | High. | Low. |
| Chromecast | Medium (depending on the network) | Maximum. | Low. |
| AirScreen (DLNA) | Tall. | Average. | Medium |
| HDMI cable | Absent. | Perfect. | High (needs adapter) |
Solving Connection and Delay Problems
Even with a perfect setup, users may find that the TV doesn't find the phone or the picture is "crumbled." Most often the problem lies in the router settings. Make sure the router doesn't turn on the "Customer Isolation" feature. AP» (AP Isolation, which prevents devices within the network from communicating with each other.
Another common cause is a crowded Wi-Fi channel. If an apartment building has a lot of networks, the signal can be unstable.Try changing the broadcast channel in the router settings or switching to a 5 GHz frequency if it is not already in use.
The secret to a stable connection
If the sound is behind the video, try changing the audio output settings on your TV. Go to Settings → Sound → Output and select Passive Speakers or Optical Output, even if you use built-in speakers. This can switch the codec and sync the stream.
Comparison of wireless methods and wired connection
Despite the convenience of wireless technologies, they have their limitations. Wi-Fi network divides bandwidth between all devices, and any spike in Internet speed or background download of updates on another gadget can cause buffering. USB-C to HDMI lacking these shortcomings.
However, to use the cable, your smartphone must support MHL or DisplayPort Alt Mode technology. Not all Xiaomi models, especially low-end and mid-range, have this feature.
The choice of method depends on your goals. Wireless streaming is ideal for viewing photos, surfing the web or showing documents. For gaming without lags or watching movies in maximum bitrate, it is better to consider the wired version or make sure that there is a powerful Wi-Fi 6 router.
💡
Wireless is a trade-off between convenience and stability. For critical impressions, always have an HDMI cable on hand as a backup option.
In conclusion, Xiaomi's ecosystem provides a flexible enough tool for displaying images. Start with the Translation method, and if you don't like the result, experiment with Chromecast or third-party apps.
