Xiaomi’s modern smartphones have long been powerful multimedia centers that can replace laptop computers and game consoles. However, the diagonal of even the largest smartphone is often not enough to comfortably watch movies in 4K or show presentations to colleagues. This is where the Wireless Display feature comes to the rescue, allowing you to instantly stream an image from your phone screen to your TV, projector or monitor.
This Miracast-based technology is built into the default MIUI or HyperOS shell, and doesn't require third-party applications to be installed. You don't need complex adapter cables or expensive hardware. It's enough that both devices are on the same LAN, and you can enjoy content on the big screen. In this article, we'll go through all the nuances of customization, possible problems and ways to solve them.
The main advantage of using built-in functionality is that it has minimal latency, which is critical not only for video, but also for gaming. Unlike streaming services, where buffering can interrupt browsing, a direct Wi-Fi Direct connection provides a stable data channel. Let's look at how to activate this capability on your device.
What is a Wireless Display and How Does It Work?
The technology behind the name “Wireless Display” on Xiaomi’s menu is an implementation of the Miracast standard. It’s a protocol developed by the Wi-Fi Alliance that allows devices to share multimedia content without using HDMI cables. Unlike Chromecast, which requires support from apps (YouTube, Netflix), Miracast broadcasts exactly what you see on a smartphone screen in real time.
This feature uses Wi-Fi Direct technology.This means that your Xiaomi phone and the receiving device (TV or set-top box) create a direct connection between themselves, bypassing the router, although often they need to be connected to the same network for initial detection.The channel bandwidth allows you to transmit high-resolution video, up to 1080p and 4K, depending on the power of the transmitter and receiver.
⚠️ Note: The Wireless Display function does not work via mobile internet (3G/4G/5G). Both devices must support Wi-Fi modules and be in the range of the wireless network.
It's important to understand the difference between streaming and mirroring. When you use an embedded button in apps like YouTube, the phone sends a link to the video stream to the TV, and the TV itself downloads content from the Internet. When you activate the Wireless Display, the phone encodes the image of its screen and sends it to an external device, which creates an exact copy of what's happening on the smartphone.
Preparation of devices for connection
Before you try to find a TV in a smartphone menu, you need to make sure that the receiving device is ready to go. Most modern Smart TVs from Samsung, LG, Sony, Philips and other manufacturers have built-in support for Miracast, but it can be called differently. For example, Samsung has Smart View, LG has Screen Share, and Sony has Duplicate screen.
You have to open the app or mode on your TV, and often you just click "Input" or "Source" on the remote and select the source of the signal "Screen Mirroring" or "Wireless Display." Then you'll have a waiting list on your TV screen. If you have an old TV without Smart features, you'll need an external console, like an Android TV Box or a special Miracast adapter that connects via HDMI.
- 📺 Make sure the TV is on and put into standby mode to connect to the wireless display.
- 📶 Check that both devices (Xiaomi smartphone and TV) are connected to the same Wi-Fi network.
- 🔋 Make sure your phone battery is at least 20% charged, as video transmission consumes a lot of energy.
- 📡 If the router is dual-band, it is advisable that both devices operate in the 5GHz band for better speeds.
Special attention should be paid to the frequency of the Wi-Fi network. To transmit high-quality video stream without artifacts and delays, it is preferable to use the 5 GHz band. In the congested 2.4 GHz band, micro-twitching of the image is possible, especially if other wireless devices are working nearby. You can check the current frequency in the router settings or in the connections on the phone.
☑️ Checking before connection
Instructions: How to turn on the Wireless Display on Xiaomi
The MIUI shell interface may vary slightly across models, but the logic remains the same. The fastest way to activate the feature is to use the control panel. Unlock the smartphone screen and swipe down from the top right corner (or bottom up, depending on the navigation settings) to open the Control Point.
In the icon menu that opens, find an icon called "Wireless Display" or "Cast." If you don't see it on the first page, scroll through the list to the left and click the edit button (usually a pencil icon or a tripod). In the list of available widgets, find the one you want and add it to the active panel. Once you click on the icon, the phone will start looking for available devices within range.
⚠️ Note: If after turning on the search function does not give results for more than 10 seconds, try restarting the Wi-Fi module on the phone or temporarily disabling Bluetooth, which can cause interference in the 2.4 GHz band. Go to Settings, select Connect and Sharing (or “Additional Features” on older versions) MIUI). You'll find Wireless Display on the screen, and when you turn on the slider, you'll start scanning, and when your TV name appears on the list, click on it, and you'll see a request on the TV screen for confirmation of connection, which you'll need to take by remote control. Model/Version MIUI Name in the Xiaomi 13 menu / HyperOS Control Point Broadcast Redmi Note 12 / MIUI 14 Settings -> Connecting Poco Wireless Display F5 / MIUI 13 Control Point Cast Xiaomi 11 / MIUI 12 Settings -> After successful pairing, the phone screen will appear on the TV. The orientation of the image will change automatically when you turn the smartphone. To exit the broadcast mode, it is enough to open the notification curtain again and press the turn off button or simply lock the phone screen, unless otherwise specified in the settings. MIUI When you connect, you can tap the gear next to the device name (720p, 1080p) Decreasing the resolution can help if the connection is unstable. Xiaomi's display and sound settings allow you to flexibly adjust the system's behavior during broadcast. One of the most useful options is the ability to turn off the smartphone screen to save battery power. This is true when watching long movies or listening to music. To activate this mode, the Wireless Display menu after connecting you need to find the appropriate switch "Switch off the screen." It is also worth paying attention to the audio settings. By default, the audio stream is transmitted to an external device. However, if you want to leave the sound on your phone (for example, to not disturb others in the room while on the TV), some audio transmission power depends on the video channel. 🔊 Sound is transmitted in stereo format, codecs are supported AAC and SBC. 🎮 In the Game mode, the input delay can be reduced by software methods, but it is impossible to completely eliminate the lags. 🔋 Turning off your phone's screen saves up to 30 percent of power during a long broadcast. If you use your phone for presentations, look at the aspect ratio. Modern phones have elongated screens, while TVs use the 16:9 standard. This can cause black bars to appear on the sides of the image, which is normal behavior of the system to prevent distortion of the image, and it is recommended that you stretch the image to the full screen of the TV through the settings of the TV itself, not the phone. 💡Use horizontal mode for games and videos. In vertical mode, the image will occupy only the central part of the TV screen, which reduces immersion and viewing convenience. The wireless display feature on Xiaomi is not only entertainment, but also a powerful tool for productivity. Connecting your phone to a large monitor or TV, you can use it as a full-fledged computer. It conveniently connects your wireless keyboard and mouse to your smartphone via Bluetooth. The mouse mouse will be broadcast to the big screen, allowing you to work comfortably with documents, tables or a browser. This method is especially effective in conjunction with office packages such as WPS Office or Google Docs. You can edit text on your phone, seeing the result comfortably on the screen with multiple applications, and the system makes it work with the need for a large-screen viewing system to run the Android application. ⚠️ Warning: When dealing with sensitive documents, make sure your Wi-Fi network is password protected.Broadcasting the screen over open networks in offices or cafes can put your data at risk of interception. For designers and photographers, the ability to display images on a calibrated monitor via a wireless connection can be useful for quickly demonstrating layouts to the customer. Although color rendering over Wi-Fi may differ slightly from the original due to compression of the video stream, for the overall evaluation of the composition, this is quite enough. Despite the declared universality, users often face a situation where Xiaomi simply does not detect the TV in the list of available devices. This often happens on office networks or if the router distributes the guest network in isolation from the main network, and the problem may lie in the antivirus settings on the PC if you try to stream the image to the computer. If the TV is old and doesn't have Miracast built-in support, the phone won't see it, so you need to buy an external receiver. If the devices are new and should work, try the following steps: Turn off and turn on Wi-Fi on both devices completely, restart your router, and make sure the latest firmware updates are installed on your TV. 🔄 Restart your router and modem even if the internet is stable. 📱 Update the “Security” app and Xiaomi system services through GetApps. 📡 Check if the router is not included in the isolation mode of customers AP (AP Isolation). 🔌 For PCs, make sure that Windows projection settings allow "Everywhere" or "Available Networks" connectivity. In some cases, the problem lies in the Wi-Fi adapter drivers on your TV or console. Manufacturers rarely release updates for older models, so the functionality can degrade over time.If nothing helps, consider using alternative broadcast apps like Google Home or TvCast that use other data protocols. 💡90% of connection problems are solved by restarting the router or switching devices to the same Wi-Fi frequency (5 GHz). Alternative Screen Translation: If the standard Wireless Display feature is unstable or not supported by your TV, the Android ecosystem offers other options. The most popular is using Google Chromecast devices or TVs with Android built-in TV. In this case, you're not using Miracast, but rather Google Cast. It's more stable for streaming videos from the Internet, because the TV loads the content on its own, saving the battery of the phone. For owners of Apple appliances and AirPlay 2-enabled TVs (many modern Samsung models, LG, Sony, iPhone and iPad can stream the screen without additional consoles. Xiaomi smartphones also received AirPlay support in some shells MIUI for regions, but more often this requires the installation of third-party applications-receivers on Smart TV. There are also wired alternatives that ensure there is no delay. USB-C to HDMI It allows you to connect your phone directly to any monitor. This is ideal for gamers playing cloud services or shooters, where every millisecond of delay over Wi-Fi can become critical. However, this method deprives you of mobility and requires the presence of a cable. Why does the picture twitch when broadcasting? The twitching of the picture (freezes) is usually caused by low Wi-Fi bandwidth or high interference. Try to get closer to the router, turn off downloads on other devices or switch to the 5 GHz band. Also, the reason can be overheating of the smartphone, because of which the processor reduces the frequency and does not have time to encode the video (you can play with the card games). However, for dynamic shooters, races or fighting games, the 100-200 ms delay that is characteristic of Wi-Fi connection will make the game uncomfortable. In such cases, it is better to use a wired connection. Is the notification sound broadcast to the TV? Yes, when the Wireless Display mode is active, the entire sound of the system is broadcast. If you receive a message or call, the sound will be played through the TV speakers. To avoid awkward situations, it is recommended to switch the phone to Do Not Disturb mode before connecting or turn off the notification sounds.
