Modern Smart TVs from Xiaomi, running on the operating system Android TV or proprietary interface PatchWall, offer a wide range of multimedia content options. However, built-in apps can't always play specific video file formats or content from a restricted website that's conveniently launched in a smartphone browser. In such situations, it becomes necessary to broadcast images directly from the mobile device's screen to a larger screen.
There are several proven ways to accomplish this task, and the specific method you choose depends on your phone model, TV firmware version, and the type of content being streamed. Wireless connection This method is the most convenient, as it eliminates unnecessary wires and distance restrictions. In most cases, the process takes no more than a minute if both devices are on the same local network.
In this article, we will take a detailed look at the technical nuances of various data transfer protocols, such as Miracast, Google Cast And DLNAYou'll learn how to configure your equipment to ensure stable, high-resolution video without lag or compression artifacts. We'll also cover common connection errors and how to quickly resolve them.
Technical requirements and equipment preparation
Before you begin setting up, make sure your TV is Xiaomi Mi TV or prefix Mi Box Connected to the same Wi-Fi network as your smartphone. This is a fundamental requirement for all streaming methods except wired HDMI. If your router supports dual-band mode, it's recommended to use the network. 5 GHz, as it provides the higher bandwidth required to transmit 4K video.
Check the operating system version on both devices. On Xiaomi TVs, software updates often bring new codecs and improve module stability. Wi-Fi DirectGo to the Settings menu, select "About device," and tap "System update." It's also a good idea to install the latest security updates on your smartphone.
⚠️ Note: If your router is configured with AP Isolation, your phone and TV won't be able to see each other, even if they're on the same network. This feature is often enabled on guest networks or corporate configurations.
For a comfortable viewing experience, make sure the Wi-Fi signal strength is sufficient in the area where the TV is located. A weak signal will result in constant buffering and reduced picture quality. Ideally, the distance between the router and TV should not exceed 10 meters if there are walls.
Using the built-in "Broadcast" function (Miracast)
The most universal method that does not require installing additional software is to use technology MiracastIn the Xiaomi ecosystem, this feature is often referred to as "Broadcast" or "Wireless Display." It allows you to mirror your smartphone's screen to a TV in real time, transmitting video and audio.
On TVs Xiaomi with shell PatchWall The signal reception app may be called "Mi Remote" or "Broadcast." You need to launch it on your TV to put the device into connection standby mode. On Android smartphones, the path to this feature may vary depending on the OS manufacturer.
☑️ Miracast connection algorithm
After selecting the TV from the list of available devices on your smartphone, a connection confirmation prompt will appear on the TV screen. Use the remote to accept the request. The phone's image will instantly appear on the big screen. It's important to understand that in this mode, the phone won't be locked, and all notifications will be visible to viewers.
Transmission quality depends on the smartphone's processor power and Wi-Fi speed. When viewing dynamic content, a slight input lag may be observed, so this method is not suitable for games that require instant reactions, but is ideal for viewing photos and videos.
Why might Miracast not work?
This feature may not be available if your phone has power-saving modes that limit background Wi-Fi usage. Some carriers also block this feature on budget plans, although this is rare.
Streaming via Google Home (Chromecast built-in)
Most modern televisions Xiaomi have built-in support for the technology Google CastThis is a more advanced protocol than simple screen cloning, as it allows you to transmit a link to the content, and the TV automatically downloads the video, freeing up the smartphone's resources.
To implement this method you will need an application Google Home, available in Play MarketAfter installation and authorization with your Google account, the app will scan the network and find your TV. Make sure you're signed in to the same account on your TV, although this isn't always a requirement for basic streaming.
Open the app Google Home, find your TV in the list of devices and tap it. In the control menu that opens, select "Cast my screen." This will start mirroring your Android desktop to your TV using Google codecs.
| Parameter | Miracast | Google Cast | DLNA |
|---|---|---|---|
| Transmission type | Screen mirroring | Mirroring / Streaming | Media files only |
| Phone addiction | High (screen should be lit) | Average | Low (can turn off the screen) |
| Video quality | Depends on the signal | Stable (adaptive) | Original (lossless) |
| iOS support | No (without third-party software) | Through applications | Yes |
The advantage of the method is through Google Home The advantage lies in better optimization of the video stream and lower smartphone power consumption. Furthermore, this protocol better handles screen orientation changes and image scaling to the TV's resolution.
Streaming content from apps (YouTube, Netflix, VK)
The best way to watch videos is to use the built-in casts feature in the apps themselves. Services like YouTube, Netflix, IVI or VK Video have a special button that allows you to send a video stream directly to the TV Xiaomi.
In the app interface, find the rectangle icon with waves in the corner (the Chromecast logo). Click it and select your TV from the list. The video will start playing on the TV, and your smartphone will act as a remote control. You can then use your phone for other tasks or even lock it.
This method is critically dependent on internet speed, as the TV will download the stream directly from the network, bypassing the smartphone. Make sure your TV has the latest versions of apps installed, as older versions may not support new codecs or authentication protocols.
⚠️ Note: Some apps may not be visible to your TV if they are installed from third-party sources (APK files) and not from the official store. Google Play on your TV. Licensed versions of the services require official apps to use Cast functions.
If the cast button is disabled, check if you're using a VPN on your smartphone or TV. Streaming video services often block content if the sender and recipient IP addresses are in different countries or are virtual.
Playing files via DLNA and local network
For viewing heavy video files stored in the phone's memory (for example, 4K HDR movies), it is best to use the protocol DLNA. Televisions Xiaomi have a built-in media player that can see shared folders on the local network.
You will need a media server app on your smartphone, for example, VLC for Android, BubbleUPnP Or a standard file manager with DLNA support. Enable the "Renderer" or "Cast to Device" function in the app settings. The TV must be on and in standby mode or on the desktop.
Open the video file on your phone, select “Play to” or “Cast” from the menu and select your Xiaomi TVThe file will begin streaming. The advantage of this method is that the TV decodes the video itself using its powerful processor, ensuring smooth playback even with complex formats.
Example path for manually adding a server (if automatic search doesn't work):Phone IP address: 192.168.1.55
Port: 8080 (standard for many media servers)
The stability of large file transfers directly depends on the quality of your Wi-Fi router. If the video starts to lag, try lowering the bitrate in your phone's player settings or moving your smartphone closer to the router.
Solution: The TV doesn't detect the phone.
One of the most common problems is when devices are on the same network but cannot detect each other. This is often due to router security settings or antivirus software on your smartphone, which blocks incoming connections to the local network.
Try rebooting your router, phone, and TV. This simple action flushes the DNS cache and updates DHCP leases, which often resolves the "invisibility" issue. Also, check if "Data Saver" mode is enabled on your phone in the Wi-Fi settings for your current network.
A secret method for old routers
If you have an older router that doesn't properly support Multicast, streaming may not work. In this case, updating your router's firmware or purchasing a modern dual-band device will help.
In some cases, resetting the network settings on your TV can help. Go to Settings → Network → Reset network settingsAfter reconnecting to Wi-Fi, the TV will re-register with the network and become discoverable.
If you're using an antivirus or firewall on Android, temporarily disable it to test. The port required for device discovery via the SSDP protocol, which is used to search for Cast devices, is often blocked.
Frequently Asked Questions (FAQ)
Is it possible to mirror an iPhone's screen to a Xiaomi TV without an Apple TV box?
Yes, it is possible. Since Xiaomi TVs don't have native AirPlay 2 support across all models, you'll need to install a third-party app from the TV's app store, such as AirScreen or Receiver for AirPlayOnce you launch the app on your TV, your iPhone will see it as an AirPlay device in Control Center.
Why is there no sound when broadcasting a video, although there is a picture?
Most often, the problem is that the wrong audio output is selected. Check the audio settings in the app you're streaming from. It's also possible that the TV is using an unsupported audio codec (such as DTS), and the sound simply isn't being decoded. In this case, installing an app can help. VLC to a TV that has built-in codecs.
Does broadcasting affect internet speed in an apartment?
Yes, when using methods where the TV downloads content from the internet (YouTube, Netflix), traffic is consumed directly from the internet. When using screen mirroring (Miracast), traffic is transmitted within the local network between the phone and the router/TV and doesn't consume external internet bandwidth, but it may consume Wi-Fi bandwidth.
How to reduce lag when playing games from your phone on TV?
For gaming, use "Game" mode in your TV's picture settings, if available. Also, make sure your phone is connected to a 5 GHz network. It's impossible to completely eliminate lag with wireless streaming due to video stream encoding technology, so for shooters, it's best to use a wired connection or play directly on your console.
