Modern multimedia capabilities allow you to turn a regular TV into a full-fledged entertainment center using only your smartphone. Owners of Xiaomi and Redmi equipment often wonder how to make the most of the bundle of gadget and large display to watch movies, photos or games. The process of synchronizing devices has become much easier thanks to the introduction of advanced wireless protocols.
The main purpose of this guide is to take a detailed look at all available connection methods, from built-in MIUI functions to the use of specialized software, learn how to ensure stable video streaming in high resolution without delay, and we will look at the nuances of operation on different operating systems and possible compatibility issues.
If you set up your hardware correctly, you'll be able to use media content in a new way, whether it's showing a presentation to your colleagues or watching a family video archive on a big screen, understanding how your screen works will be a key skill. Let's move from theory to practice.
Technology of wireless image transmission
Before you start setting up, you need to understand the fundamental differences between the technologies that Xiaomi TV uses and smartphones of this brand. Understanding the principles of operation of each protocol will help to avoid confusion and choose the best option for your situation.
The most common standard is Miracast, which allows real-time displays of the screen, which is operating system-level and doesn't require an Internet connection using only a local Wi-Fi network, which is most often referred to as "Translation" on the smartphone menu.
The second key player is the Google Chromecast ecosystem, which, unlike mirroring, is not a replica of the screen, but a link to content that the TV plays itself, which reduces the load on the phone's battery and allows it to be used for other tasks while watching.
Also worth mentioning is the DLNA protocol, which is designed primarily for transferring media files (photos, videos, music) from your phone to TV. It does not know how to duplicate the application interface, but it is great at playing heavy video files from the device’s memory.
⚠️ Warning: Make sure your router supports 5GHz High-resolution Video Streaming (FullHD and High-Resolution) 4K) 2.4 GHz network can cause jerks and desynchronization of sound.
The choice of a specific technology depends on your goals: for games and displays, you need Miracast, and for watching videos from online cinemas, Chromecast is better suited.
Preparation of equipment and network
Successful connections depend on proper pre-preparedness of both devices, and ignoring basic requirements often results in the TV simply not seeing the phone.
The first and most important rule is that both devices must be on the same LAN, if your smartphone is connected to a guest Wi-Fi network and your TV is on the main Wi-Fi network, or one of them uses 4G mobile Internet, you can't set up the connection. Check the router's settings and make sure that the AP Isolation is turned off.
The second step is to update the software. Manufacturers regularly release patches that improve the stability of wireless modules. Go to the settings of the Xiaomi Mi TV and check for PatchWall or Android TV updates.
It is also recommended to restart the router before setting up. Prolonged operation of network equipment can lead to buffer overflows or IP-address conflicts, which prevents the detection of devices on the local network.
☑️ Checking before connection
Performing these simple steps eliminates 90% of connection problems during the device discovery phase.
Use of the built-in "Translation" function
Xiaomi, Redmi and POCO smartphones have a built-in tool for quick image output, which is the most convenient method, since it does not require additional software installation and works out of the box.
To activate the function, lower the notification curtain and find the Translation icon (sometimes called Projection or Cast). If the icon is not available in quick access, click on the menu edit pencil and add it from there. Alternative path: go to Settings → Connection and Sharing → Broadcast.
Once the feature is enabled, the phone will start searching for available devices on the network. On the Xiaomi TV screen, a connection request may appear, which must be confirmed by the remote control. In some TV models, you need to pre-start the Media or Wireless Monitor application.
The quality of the picture depends on the power of the Wi-Fi module. Using this method, the phone screen is completely duplicated on TV, so notifications and calls will also be visible on the large screen.
⚠️ Attention: Translation significantly increases battery consumption and smartphone heat. For prolonged use, it is recommended to keep the phone connected to the charger.
If the list of devices is empty, try turning off and re-enable Wi-Fi on your smartphone, sometimes helping to temporarily disconnect the mobile Internet.
Broadcasting via Google Home (Chromecast)
For Android TVs, which include Xiaomi Mi TV models, native support for Chromecast technology is standard.This allows you to stream content from apps directly without straining the phone's processor.
To work, you’ll need the Google Home app, which is often pre-installed on Google-enabled smartphones: Open the app, find your TV in the list of devices, and click the “Cast my screen” button.
This is particularly effective for watching videos from YouTube, Netflix or online cinemas, and the player apps themselves also have a button with a TV icon, and you click on it and you tell the TV to play, and the phone acts as a remote control.
The main advantage of Chromecast over Miracast is the ability to use your phone independently of your TV. You can roll up a video, respond to a message, or even turn off your smartphone screen, and the video on your TV will go on.
What if Google Home doesn’t see TV?
Connection stability in this mode is usually higher, as the data flow goes directly from the router to the TV, bypassing the phone after initiation.
Third-party applications for enhanced capabilities
Staff funds are sometimes not enough, especially if you need to broadcast content from the Internet. DRM-And in these cases, third-party solutions come to the rescue.
One of the most popular apps is AirScreen, which is installed on a TV (via Google Play Store on TV) and emulates various protocols, including AirPlay for iPhone owners, making it possible to connect Apple appliances to a Xiaomi TV without crutches.
For advanced users, an interesting use case DLNA-By installing an application like BubbleUPnP or VLC You can share a folder of video on your phone and open it through the TV's built-in player, and it allows you to play files of any format that the TV can "know" to rip off.
There are also paid applications that offer audio transmission separately from video or control of a computer via a phone with an image output to TV. However, for basic tasks, there are usually free analogues.
| Annex | Type | Platform TV | Features |
|---|---|---|---|
| AirScreen | Receiver | Android TV | Support for AirPlay, Miracast, DLNA |
| LocalCast | Client | Any (with Chromecast) | Working with cloud storage |
| Web Video Caster | Client | Anybody. | Broadcasting video from the browser |
| TeamViewer Host | Remote access | Android TV | Full control of the PC/Phone screen |
Using third-party software gives flexibility, but can introduce additional latency, which is critical for dynamic games.
Wired connection: HDMI and USB-C
Wireless technology is convenient, but it doesn’t always provide the quality and stability needed. Cable is better for eSports games or 4K HDR content without compression.
You’ll need a USB-C to HDMI adapter. It’s important to understand that the USB-C port on your phone should support the DisplayPort Alt Mode standard. Budget Redmi and POCO models often have a charging and data only port (USB 2.0) that doesn’t support video output.
If your flagship Xiaomi smartphone supports video output, just connect the adapter to the phone and HDMI-Connect the adapter to the TV, and the source switching on the TV is usually automatic.
This method ensures zero latency and maximum picture quality, and the phone will charge during use if the adapter has an additional power port.
💡
When buying a USB-C to HDMI adapter, pay attention to support for 4K@60Hz resolution. Cheap cables are often limited to 30Hz, making cursor and video movement jittery.
You can check the video output support in the model specifications on the official website or try to connect the adapter. If there is no image, unfortunately, software cannot fix this.
Addressing problems and delays
Even with a perfect setup, there can be failures, and let's look at the most common scenarios and how to fix them.
If there is an image but no sound, check the audio output settings in Android. Sometimes the sound continues to go through the phone's speaker while the picture is on TV. In the notification curtain or in the Bluetooth/Connection settings, select the audio output device - your TV.
A black screen when running protected video (Netflix, Disney+) through mirroring (Miracast) is normal behavior due to HDCP protection. In this case, only using an embedded app on a TV or Chromecast technology helps, but not Screen Translation.
High latency makes it impossible to play shooters, and the only way to reduce it is to switch to a wired connection or use Game mode in the settings of the TV, which disables excessive post-processing of the image.
