Modern mobile devices have performance comparable to the gaming consoles of the previous generation, but the diagonal of the smartphone screen often limits the enjoyment of the process. Owners of Xiaomi equipment are in a winning position, as the brand ecosystem offers many convenient ways to broadcast images to the big screen. Connecting a smartphone to a TV allows you not only to watch movies, but also turns the gadget into a full-fledged controller for games, providing immersion in the virtual world.
There are several proven methods of organizing wireless connection, each of which has its own characteristics depending on the model of your TV and the version of the Android operating system. Wireless data transfer requires a stable channel, while wired connection guarantees minimal input delay, which is critical for dynamic shooters and racing. The choice of the optimal method depends on your priorities: image quality or response speed.
In this guide, we will take a detailed look at all available synchronization options, starting with the built-in system functions. MIUI You'll learn how to set up Miracast, use Google Cast protocol, and what cables are needed to create direct communication. HDMI-The right network settings and display will allow you to enjoy high-resolution gameplay without annoying lags.
Preparation of equipment and network for broadcasting
Before you start setting up, you need to make sure that all devices are ready to interact. The fundamental condition for most wireless methods is to have your smartphone and TV on the same LAN. If your router supports dual-band, it is highly advisable to connect both devices to a 5 GHz network, as it provides higher bandwidth and less interference compared to the 2.4 GHz band.
Make sure that Xiaomi TV (Mi TV or Android TV) has the latest firmware installed. Manufacturers regularly release updates that optimize Wi-Fi modules and media transfer protocols. You can check by going to Settings → About TV → System Update. It is also recommended to update system components on your smartphone, especially if you use a MIUI or HyperOS shell.
⚠️ Note: If your router distributes networks with the same name (SSID) For 2.4 and 5 GHz, devices can automatically switch between them, which will cause a connection break. For stable play, it is better to split networks or force the gadgets to 5 GHz.
For wired connection, you will need a special adapter, since most Xiaomi smartphones do not have a native HDMI port. The type of adapter depends on the charging connector of your phone: USB Type-C or outdated Micro-USB. It is important to purchase cables that support the MHL or Slimport standard, which allow you to transmit a video signal through the charging port.
☑️ Connection readiness
Use of the built-in Mi Drop and Broadcast function
The easiest way to do this without having to install additional software is to use the built-in MIUI shell functionality, which is called "Translation" or "Wireless display" on most Xiaomi models, which is based on the Miracast protocol, which allows you to duplicate the screen of your smartphone on your TV in real time, which is ideal for turn-based strategies or card games where you don't need an instant reaction.
To activate, open the notification curtain and find the Translation icon or go to Settings → Connection and Sharing → Broadcast. Once you turn on the search, the phone will start scanning available devices. On a Xiaomi TV with PatchWall or Android TV, you may need to run the “Miracast” or “Wireless Display” app from the installed list to make the device visible.
Once the connection is established, the image from the phone is completely copied to the large screen. However, it should be noted that in this mode the phone can force the image to orient vertically if the game does not support horizontal mode, or stretch the image to the entire TV screen, distorting the proportions. To correct, click on the gear in the broadcast menu and select "All screen" or "16:9".
Why can the broadcast be interrupted?
Broadcasting via Google Home and Chromecast
A more advanced and stable method is to use Google Cast technology. Xiaomi TVs running on Android TV have built-in Chromecast support. To implement this method, you will need the Google Home app, which can be downloaded from the Play Market. This method often provides better picture quality and lower latency than the standard Miracast.
Launch the Google Home app on your smartphone and find your TV in the list of devices. Click on the TV name, then select the "Cast my screen" button. The system will warn you that all activities on the phone will be visible on the TV, including notifications and calls. Confirm the action, and the screen of the smartphone will appear on the TV panel.
The advantage of this method is that you can control the broadcast directly from the application. You can adjust the volume, stop the transmission or switch devices without interrupting the game. In addition, many modern games have a built-in Cast button that allows you to output only gameplay, leaving the control interface on the phone, which is much more convenient.
| Parameter | Miracast (Translation) | Google Cast (Chromecast) | Wireless (HDMI) |
|---|---|---|---|
| Delay (Input Lag) | High (100-300 ms) | Medium (50-150 ms) | Minimum (<10 ms) |
| Image quality | Depends on the Wi-Fi signal. | Adaptive (up to 1080p/4K) | Native (up to 4K HDR) |
| Battery consumption | High-pitched | Medium. | Charging the phone |
| Difficulty setting up | Low. | Medium | Low (need cable) |
💡
To reduce latency when using Google Cast, close all background apps on your phone to free up the CPU resources to encode the video stream.
Third-party apps for gamers
If standard tools don't deliver the right performance, you should look at specialized software. Applications like ApowerMirror or TeamViewer offer advanced control capabilities, which allow you not only to broadcast an image, but also to use your phone as a touchpad or connect a physical gamepad to your TV, controlling it via a smartphone.
Steam Link technology is particularly noteworthy. If your games are installed on your computer, you can stream them to your phone and then display the image from your phone to your Xiaomi TV. However, there is a more direct way: the Steam Link app is available in the Google Play store on the Xiaomi TV itself (Android TV), in which case the phone is used exclusively as a controller, and all heavy graphics are processed by the PC, which gives the best quality.
For owners of Xiaomi devices with support for desktop mode (similar to Samsung DeX, found in flagship models), connecting to a TV can turn the interface into a kind of Windows. This allows you to run mobile games in window mode, while opening the browser or messengers on the large screen, activation of this mode usually occurs automatically when you connect through the Internet. HDMI-adapter.
⚠️ Note: When using third-party broadcast apps, make sure you grant them all the permissions you request, including "Mapping Up on Other Apps." Without this right, game management can be blocked by Android security.
Wired connection through HDMI-adapter
For esports disciplines like PUBG Mobile, Call of Duty or Asphalt, where the bill goes on milliseconds, wireless methods may not be effective enough. The only solution to achieve zero latency is wired connectivity. Xiaomi smartphones with a USB Type-C port (Mi, Xiaomi, Redmi Note Pro series) need adapters that support the USB-C to HDMI standard.
It is important to understand that not all USB-C ports in Xiaomi smartphones support video output. DisplayPort Alt Mode feature is usually present in flagship models (the Mi 9 series, Mi 10, Mi 11, Xiaomi 12/13/14 and their Pro/Ultra versions). In budget models of Redmi and POCO, this port is often limited to USB 2.0 speed and can not transfer video. Before buying an adapter, it is recommended to check the specifications of your model on the official website.
The connection process is elemental: insert the adapter into the phone charging connector, connect the HDMI cable from the adapter to the TV and select the appropriate signal source (Input) on the TV remote. The phone automatically recognizes the external display. Unlike wireless methods, there is no compression of the video stream, which ensures the absence of artifacts and “squares” in dynamic scenes.
Procedure for wired connection:
1. Connect the USB-C -> HDMI adapter to the smartphone.
2. Connect the adapter and TV with an HDMI cable.
3. On the TV remote, press the "Input" button and select a port (e.g. HDMI 1).
4. on the phone to accept a request for debugging / access permission (if available).💡
Wired connection is the only way to get a stable 60 FPS and no input delay required for competitive online play.
Optimizing settings for a comfortable game
After successfully displaying the image on the Xiaomi TV, it is recommended to perform the final configuration of the display parameters. Go to the settings of the TV image and switch the mode to the Game Mode position. This disables various post-processing algorithms such as noise reduction and motion smoothing, which add significant input delay.
Also, check the resolution settings. If the phone displays a picture in non-standard resolution, the TV can scale it, which blurs the interface. In the phone settings (Screen or Translation section), try changing the output resolution to 1920×1080 or 3840×2160 depending on the capabilities of your panel. The refresh rate is preferably set to 60 Hz or higher if the TV supports 120 Hz.
Remember to use sound. When broadcasting, audio can be transmitted with a delay relative to video. In the settings of Bluetooth audio systems or Xiaomi TV (Settings → Sound → Synchronization of sound), you can adjust this setting. For best effect, use an external acoustic system or soundbar connected via optical output or ARC.
In conclusion, the choice of method depends on your goals: for casual games, there is enough built-in broadcast, and for hardcore gaming, you should use cable. Xiaomi ecosystem provides flexible tools for any scenario, turning a regular TV into a center of home entertainment.
