Modern Xiaomi smartphones have powerful screens, but 6-inch diagonals are often not enough to watch family movies or presentations. Fortunately, the Mi Home ecosystem and the MIUI (or HyperOS) operating system provide built-in tools for wireless image transfer. You don't need complex HDMI cables or adapters if you have a stable Wi-Fi network at hand. The process of synchronizing a device with a large screen takes only a couple of minutes, if you know the right sequence of actions.
There are several ways to do this, from the standard Translation feature to third-party applications that support DLNA and AirPlay protocols. The choice of method depends on the type of your TV: whether it is a Smart TV with Miracast support or a regular screen with a console. In this article, we will discuss all current connectivity options, possible problems with audio and video codecs, and ways to minimize image latency during games.
Before you start setting up, make sure that both your smartphone and your TV are connected to the same wireless network, a critical condition that makes detecting devices impossible. The router must support the 5 GHz standard for high-resolution video without buffering, although it can also work at 2.4 GHz with lower picture quality.
Preparation of equipment and network
The first step is to check the compatibility of your TV.Most modern smarts TV Samsung, LG, Sony and Philips have built-in Miracast (Wi-Fi Direct) support, and if you have a TV without Smart features, you'll need to use an external set-top box, such as a TV set-top box, MI TV Stick or Chromecast connected to HDMI-port.
The quality of the broadcast depends on the speed of the router and the distance to it. If you plan to watch movies in 4K, make sure that your router supports the standard Wi-Fi AC or AX. In densely built apartment buildings, the channels can be congested, which leads to jerks of the image.
- ๐ก Connect both devices to the same Wi-Fi network (SSID must be completely identical).
- ๐บ Activate the signal reception mode on your TV (often called Screen Share, Miracast, or simply Translationยป).
- ๐ฑ Make sure that your Xiaomi phone has Wi-Fi and Bluetooth enabled (for initial search).
- โก Check the battery power of your smartphone, as active video transmission consumes energy quickly.
โ ๏ธ Note: If your router gives away two networks with the same name (2.4 GHz and 5 GHz), try switching your phone and TV to one of them forcibly, as some older TV models do not see the device in different frequency bands.
For stable operation, it is also recommended to update the TV firmware to the latest version. Manufacturers often release patches that improve compatibility with Xiaomi mobile devices. You can check for updates in the TV settings menu, usually in the Support โ Software Update section.
Use of the built-in "Translation" function
The easiest and fastest way to display an image is to use Xiaomiโs system utility, which is built into the MIUI shell and does not require additional software, which is based on the Wi-Fi Certified Miracast standard, which is supported by most TV manufacturers.
To start, open the notification curtain control center and find the Translation icon. If it's not on the first screen, click the edit button (usually three dots or a pencil icon) and drag the icon to the active area. Once turned on, automatically search for available devices within network range.
โ๏ธ Pre-broadcast checks
When the name of your TV appears on the list, tap it. The TV screen may have a request for confirmation of connection, it must be confirmed by the remote control, then the smartphone screen is completely copied to the large display, you can flip the phone into horizontal mode, and the image will occupy the entire screen.
Importantly, this method broadcasts the entire screen of the smartphone, which means that incoming notifications, messaging messages and system sounds will be visible and audible to everyone in the room, and for privacy, it is better to turn on the Do Not Disturb mode.
Broadcasting through YouTube and streaming services
If your goal is to watch videos, rather than show the phone interface, youโd better use the built-in โCastโ feature inside the apps themselves. Services like YouTube, Netflix, IVI, and Kinopoisk use Google Cast or DIAL, which provides better picture quality and less battery load.
Unlike system broadcasting, the phone is just a remote control, and the video is buffered and played directly from the Internet by the TV itself, allowing you to roll up the YouTube app on your phone, read the news, or even turn off the screen of your smartphone while the movie is on the TV.
The algorithm of actions is very simple:
- Launch the YouTube app on Xiaomiโs smartphone.
- Click on the icon of the rectangle with waves (usually in the upper right corner).
- Select your TV from the list of available devices.
- The video will automatically run on the big screen.
โ ๏ธ Note: If the broadcast icon doesnโt appear or is grey, make sure your Google accounts are on your phone and smart. TV (if it's Android. TV) The devices are in the same subnet or in the same subnet.
Why does video slow down when streaming via YouTube?
The advantage of this method is to support high resolution 4K and HDR, if your tariff and hardware allow it. System broadcasting is often limited to Full HD due to the bandwidth of the Wi-Fi Direct channel.
Using third-party apps for Xiaomi
Embedded tools donโt always work perfectly, especially with older or brand-specific TVs, and in these cases, customized apps from GetApps or Google Play come to the rescue, allowing you to customize more flexible codec options and resolutions.
One popular solution is Web Video Caster or TV Cast, which can pull video streams from sites that don't have official apps and send them to TV, and it's important for watching videos from various online cinemas that don't support the standard Cast protocol.
| Annex | Protocol | Features | Advertising |
|---|---|---|---|
| Mi Remote | IR / Wi-Fi | Official, IR port management | No. |
| Web Video Caster | DLNA / Cast | Support for subtitles, many formats | Got it. |
| LocalCast | DLNA / AirPlay | Working with local files | There is. |
| Screen Mirroring | Miracast | Alternative to System Translation | There is. |
When installing third-party software, be sure to check the permissions requested. The screen broadcasting app doesn't need access to your contacts or SMS. Limit your rights to media files and a local network for data security.
Sound problems and their solution
A common problem with wireless connectivity is the lack of sound on the TV or its desynchronization with video, which is because the Miracast protocol by default can transmit the audio stream separately or not at all if the codec is not supported by the TV.
If you have an image and no sound, check the media settings in the broadcast menu. On some Xiaomi models, when you activate the Translation screen, a floating window with settings appears, you can force the output of sound to an external device, and it is also worth checking whether the phone has Vibration Only mode.
In case of desynchronization (when the actorsโ lips move earlier or later than the sound), try to reduce the video quality in the streaming service settings. High bitrate takes time to decode, and the audio track can outpace the video. Rebooting the router also often solves problems with data packet delays.
โ ๏ธ Note: When viewing content with protected DRM (licensed films 4K) The system broadcast of the screen can show a black screen instead of an image. This is a protection against piracy. In such cases, use only the built-in Cast in the service application.
For games, sound delay can be critical. Xiaomi's built-in stream has a Game mode that prioritizes the video stream, but it's impossible to completely remove the lag over Wi-Fi. For competitive shooters, it's better to use a wired connection or broadcast only a picture, and leave the sound on the phone.
Alternative methods: Cable and consoles
If the wireless connection is unstable or the picture quality does not meet the requirements, there is always the option of using cable. For modern Xiaomi smartphones with a USB Type-C port, you can use a Type-C to HDMI adapter.
However, not all Xiaomi models support video output via USB. the DisplayPort Alt Mode feature is available mainly in the flagship series (Mi 10, Mi 11, Xiaomi 12/13/14 Pro). Budget models Redmi and POCO often do not have this capability, and the adapter will not work.
๐ก
If you have a Mi Box or Mi TV Stick, use Google Home to create a pair, which provides the most stable connection in the Android ecosystem.
Using Android TV or Apple TV is a great way to bring your iPhone to your Xiaomi TV via AirPlay, or vice versa, and the versatility of the platform allows you to combine devices from different brands into a single multimedia system.
In conclusion, the choice of method depends on your tasks: for quick display of photos, the built-in feature is suitable, for movies - YouTube Cast, and for games with minimal latency - only cable or specialized gaming streaming services.
