Xiaomi’s modern smartphones feature powerful multimedia capabilities that allow you to display images on large displays without using cables. A wireless screen feature, also known as Miracast or Translation, allows you to watch photos, videos and games on your TV or monitor, which is especially convenient when you need to show a presentation to colleagues or run a film in high resolution at home theater.
Activation of this option may vary depending on the version of the MIUI or HyperOS operating system. Users often find that the icon is hidden in the menu or the switch does not work due to network restrictions. In this article, we will discuss in detail all the nuances of the configuration, possible problems and ways to solve them for stable connection operation.
Successful device synchronization requires several technical aspects, such as support for Wi-Fi Direct standards and signal frequency. Wireless data transfer requires a stable communication channel, so router quality and distance between gadgets are critical. Understanding the technology will help to avoid image delays and sound dissynchronization.
The principle of Miracast technology on Xiaomi smartphones
Miracast technology is based on the Wi-Fi Direct standard, which allows you to transmit video signals directly between devices without having to connect to the local network via the router. Xiaomi smartphone in this case acts as a source of the signal (source), and the TV or console accepts this stream, which provides high-resolution image transmission, up to 4K, with minimal quality losses.
Unlike Chromecast, which requires a middleman app and an internet connection to stream content from the cloud, a wireless screen broadcasts exactly what’s happening on a phone’s display in real time. The signal is transmitted directly over Wi-Fi, so you may not need to have internet at all if the devices support a direct connection, making it ideal for showcasing games or working with documents in places without access to the global network.
MIUI has a built-in decoder that compresses the video stream before sending it and unpacks it on the receiving side. This process requires processing resources, so older smartphone models can have a slight cursor delay or game movement. However, for viewing static content or video files, this delay is almost invisible to the human eye.
⚠️ Attention: When using the wireless screen, the smartphone battery discharges much faster due to the high load on the Wi-Fi module and the processor. It is recommended to keep the device connected to charging or have a power bank on hand.
Preparation of devices for connection
Before attempting to enable the feature, you need to make sure that both devices are ready to exchange data. The first step is to check the compatibility of the TV or projector. Most modern Smart TVs from Samsung, LG, Sony and other manufacturers support the Wi-Fi Direct standard natively. If you have a regular TV, you will need a separate console, for example, Android TV Box or Chromecast.
The second important aspect is the software version. Make sure your Xiaomi has the latest security and system updates installed. Often, manufacturers release patches that fix communication protocol errors. Check for updates in Settings → About Phone → MIUI version.
Also worth paying attention to the frequency of the Wi-Fi module. To transmit a high-quality video stream without artifacts and brakes, it is preferable to use the 5 GHz bandwidth. It provides higher bandwidth, although it has a smaller range compared to 2.4 GHz. If the router is dual-band, it is better to connect both devices to a 5 GHz network.
☑️ Checking before connection
Remember that Bluetooth should also be activated on a smartphone, as it is often used to initially detect devices and pair before starting to transmit a video stream.Bluetooth disabling can result in the TV simply not showing up on the list of available devices.
How to turn on the wireless screen through the notification curtain
The fastest way to activate the broadcast is to use the control panel. On Xiaomi smartphones, this is done by swiping down from the top of the screen. In the icon menu that opens, you need to find an item called Translation or Wireless Screen. If there is no such icon in the visible part, you should click on the edit button (usually a pencil icon or three dots) and add the desired switch.
Once you click on the icon, the system will automatically search for available devices within range. A list of found TVs and consoles will appear on the screen. Select your device from the list, and in a few seconds the image from the phone should appear on the large screen. The process takes no more than 10-15 seconds with a stable signal.
In some versions of the HyperOS shell, this switch may be called Translation and have an icon in the form of a rectangle with waves. Once activated, the phone may suggest that you choose to operate: mirror the entire screen or broadcast only multimedia content.
⚠️ Note: If you click on the Translation button and you see a message saying “Device not found”, make sure that the signal reception function (Screen Mirroring, Smart View or similar) is enabled on the TV).
It’s worth noting that in horizontal orientation mode, some apps can automatically expand the image to the entire TV screen, hiding the status bar of the smartphone, which creates a full immersion effect, but limits access to the phone’s system notifications while watching.
Configure through the system settings menu
If the fast access is not working or the icon is missing, you can use the deep settings menu. The path to the function may vary slightly depending on the version of MIUI, but the general logic is saved. Go to Settings → Connection and Sharing → Broadcast. In some cases, this item may be in the “Connections” or “Additional Features”.
In the menu that opens, you need to activate the "Enable" slider, and then the phone goes into search mode, and there are often additional settings available, such as the name of the device that will see the TV and security requirements, for example, you can set a password request for each new connection, so that neighbors can not accidentally broadcast their screen to your TV.
Inside the menu, you can also have a "Start Automatically" feature that allows the phone to search for the TV itself when connecting to a home Wi-Fi network, which is convenient for constant use, but can consume battery if you are in places with many open networks.
For users who often use projectors for work, it is possible to adjust the output resolution separately, which allows you to reduce the load on the smartphone if the projector does not support high resolution, thereby extending battery life.
Use of Mi Remote and Third Party Solutions
Xiaomi’s ecosystem preinstalled Mi Remote (Mi Remote) app, which is primarily designed to control infrared hardware. However, in some regions and firmware versions, it is integrated with smart home features and can offer a connection to Mi TV. If you have a Xiaomi or Redmi TV, this app will provide the best compatibility and minimal latency.
For other brands that don't support Miracast natively or are not stable, you can use third-party apps. A popular solution is AirScreen or ApowerMirror. They install a special server on the TV (if it's a Smart TV on Android) that receives a signal from the phone. This is a workaround that often helps when standard methods are powerless.
Third-party apps often provide advanced functionality, such as the ability to control your phone from a TV remote, transmit sound separately from the image, or record a screen during a broadcast. However, it is worth considering that free versions of such programs may contain advertising or have session time limits.
| Connection method | Required SOUTH | Delay (Latency) | Quality. |
|---|---|---|---|
| The curtain (Miracast) | Systemic | Low. | High. |
| Mi Remote (Mi TV) | Mi Remote / MIUI TV | Minimum | Maximum. |
| Third-party annexes | AirScreen et al. | Medium | Depends on the network. |
| Google Home | Google Home | Tall. | streaming |
When using third-party solutions, it is important to carefully read the permissions the application requests. Access to a microphone or file system may be necessary to transmit audio or media, but excessive access rights pose risks to privacy.
The solution: Why the connection is not working
One of the most common problems is when the phone simply doesn't see the TV, and most often, the reason is that the devices are connected to different Wi-Fi networks. Even if the router is single, but the guest network is turned on, or the 2.4 and 5 GHz division with different names (SSIDs), the devices may not be detecting each other. Make sure the network names are identical.
The second common reason is antivirus programs or firewalls on the router that block ports used for Wi-Fi Direct. Try temporarily disabling traffic filtering or creating an exception for local devices. Also helps reboot router, which clears the cache DHCP and resolve conflicts IP-address.
If there is an image but no sound, check the audio output settings in the app itself that you are broadcasting. Some video players default to only send audio to the phone speaker. System audio settings may also have Mono mode active or the device output selected incorrectly.
What to do if the image twitches?
⚠️ Attention: When in use VPN On a smartphone, the wireless screen often stops working because the virtual network changes the device's local address. VPN before the session.
Optimizing Productivity and Safety
For gamers who use a wireless screen to display games on the TV, input lag is critical. To minimize this, the phone settings should enable Game or Game Turbo mode, which prioritizes the game's network traffic, and it is also recommended to turn off the automatic brightness of the smartphone screen so that the light sensor does not consume the processor resources.
Security issues can't be ignored either. Screen broadcasting means anyone who connects to your session will see all your notifications, including SMS codes and messaging messages.Be sure to turn on Do Not Disturb mode before connecting to public displays (in hotels, conference rooms) and hide confidential notifications.
Regularly cleaning the system cache can help if the function has started to work unstable over time. Go to Settings → Apps → All Apps → Broadcast (or Wireless Display) and click Clear Cache. This will not delete your personal data, but reset the settings of the network module responsible for this function.
💡
Use Screen Replay mode only for trusted networks. In public areas, it is safer to stream content directly from an app (like YouTube) using the Cast button inside the player, rather than duplicating the entire screen.
Remember that long-term broadcasting leads to heating of the smartphone case. Remove the case if it is dense and does not remove heat well to avoid trottling (reduced performance) of the processor, which can cause image jerks.
💡
The stability of the wireless screen is 90% dependent on the quality of the Wi-Fi signal and the absence of interference in the air, so the router must be in line of sight from the devices.
