Modern Xiaomi Smart TVs have long since ceased to be just screens for viewing air channels, becoming powerful multimedia centers capable of playing content from any source. The ability to stream an image from a tablet to a large screen opens up access to high-resolution movies, mobile games with improved graphics and full-wall presentations. Owners of Mi Pad, Samsung Galaxy Tab or budget Chinese tablets often face the need to quickly organize viewing photos or video files stored on an internal drive.
The connection process can vary depending on your tablet’s operating system and the firmware version of your Android TV or PatchWall. There are several proven methods, ranging from wireless data protocols to a physical cable connection. The best way to choose depends on what you plan to do: watch videos from the gallery, play games or demonstrate the desktop in real time.
In this article, we will take a closer look at all the connectivity options available, focusing on network settings and eliminating common synchronization errors, how to minimize latency in games and how to ensure stable video streaming in 4K resolution without jerks and artifacts. Properly configured will turn your tablet into a universal multimedia content management remote.
Wireless streaming via built-in Mi Cast function
The easiest and most popular way to do this without additional software is to use native Mi Cast technology built into the shell of Xiaomi TVs, which is based on Miracast and DLNA protocols, allowing you to duplicate the tablet screen almost instantly. It is critical to work successfully that both devices are on the same local Wi-Fi network, preferably at 5 GHz to ensure sufficient channel bandwidth.
To activate reception on the TV side, you need to go to the application menu and find the standard Wireless Monitor (or Mi Cast) application. After launch, the connection wait interface will appear on the screen, which will display the device name and readiness status. Some TV models require manual switching of the signal source in the input menu (Input) to the corresponding wireless port.
On a tablet, the procedure may vary depending on the manufacturer and version of the Android operating system. Usually, just unlock the screen, swipe the notifications down and find the Broadcast, Smart View or Projection button. After scanning the network, the name of your Xiaomi TV will appear in the list of available devices, which you need to click on to start pairing.
💡
To minimize latency when playing, use a router that supports the Wi-Fi 6 standard and make sure the tablet is in line of sight from the access point.
Using Google Chromecast built-in technology
Most modern Xiaomi TVs run Android TV, which includes built-in support for Google Chromecast technology. This method differs from simple screen duplication in that it allows you to stream content directly from applications without loading the tablet processor. The TV itself downloads video stream from the Internet while the tablet acts as a remote control.
To get started, make sure that the tablet has the latest versions of Google Home and YouTube apps. When you try to play a video in a supported app (for example, YouTube, Netflix, Vimeo), a characteristic wave rectangle icon will appear in the corner of the video player.
If you want to broadcast your desktop (browser tabs, games, documents), use the Google Home app. Select your TV from the list of devices, click Broadcast and confirm permission to access. Image quality in this mode may be lower than when using native Mi Cast, but compatibility with various applications is much higher.
☑️ Check before connecting Chromecast
Connection via HDMI cable and adapters
When you want maximum image quality without compression or the wireless network is overloaded, the only right solution is to physically connect through the HDMI port. Tablets rarely come with full-size ports, so you will need a special adapter (adapter) depending on the type of charger your device: USB Type-C, Micro-USB or Lightning (for iPad).
It is important to understand that not all tablets support video output via a charging port. MHL (Mobile High-Definition Link) or DisplayPort Alt Mode technology must be hardware implemented in the device. Cheap models of the budget segment often do not have this feature, and connecting the cable in this case will not give any result, except charging the battery.
The connection process is elemental: insert the adapter into the tablet connector, connect the HDMI cable to the adapter and TV, then select the appropriate signal source in the TV menu (for example, HDMI 1). The image should appear automatically, but in some cases you need to activate debugging mode or select the output mode in the developer settings.
⚠️ Note: When using long cables HDMI (more than 3 meters) without an active signal amplifier, interference, flickering or complete absence of image, especially at resolution, may occur. 4K.
Broadcasting through third-party applications and DLNA
If the built-in functions are not working properly or require extension of functionality, third-party applications using the DLNA protocol come to the rescue. Programs such as LocalCast, BubbleUPnP or XCast allow you to stream media files (video, photos, music) directly to the TV, bypassing the system limitations of the tablet operating system.
The principle is that the app scans the local network, finds the media server (in this case, a Xiaomi TV), and sends it a link to the file or the data stream itself, which is ideal for viewing video files in formats that the built-in TV player does not support, since the TV itself decodes.
To set up, you just need to install the selected application on the tablet, open the desired video file in it and click the connection button (usually the TV icon). In the list of devices, select your Xiaomi TV. Some applications allow you to create playlists and manage the playback queue, which is convenient for organizing a home theater.
Why is the sound lost when broadcasting via DLNA?
Comparison of Connection Methods and Their Characteristics
The choice of connection method directly affects the user experience. Wireless methods are convenient for their simplicity, but are subject to interference and delays. Wireless connection guarantees stability, but limits the mobility of the device. Below is a comparative table of the main characteristics of different methods of image transmission.
| Method | Image quality | Delay (Latency) | Stability | Requirements |
|---|---|---|---|---|
| Mi Cast (Miracast) | High (up to 4K) | Medium | Depends on Wi-Fi. | One Wi-Fi network |
| Google Chromecast | High (up to 4K HDR) | Low (for streams) | Tall. | Internet, Google account |
| HDMI Cable | Maximum (Lossless) | Minimum | Absolute. | Adapter, cable. |
| DLNA (LocalCast) | Depends on the file. | Low. | Tall. | Client application |
From the data, we can conclude that Chromecast and DLNA are optimal for watching movies, since they unload the tablet. Mi Cast or cable is better for showing presentations or working with documents, since they provide accurate real-time duplication of the interface.

HDMI cable connection is the only way to get a picture without compression and with zero latency, which is critical for dynamic games.
Troubleshooting and troubleshooting
Even when set up correctly, there can be technical failures. One of the most common problems is that the TV doesn't see the tablet on the list of available devices. 90% of the time, this is because the devices are connected to different networks (for example, one to the 2.4 GHz guest network and another to the main 5 GHz) or because client isolation on the router is enabled.
Another common issue is desynchronizing sound and image or twitching images periodically, which indicates a lack of bandwidth, try turning off other devices that consume traffic, or move the router closer to the TV, and rebooting the Wi-Fi module on both devices also helps.
If you connect to an HDMI black screen, check the output resolution. Some older TVs or cables don't support 4K at 60Hz. Try lowering the refresh rate or resolution to 1080p in your tablet settings (Developers or Screen).
⚠️ Note: When using cheap Chinese adapters HDMI If the image blinks, connect the adapter to an external power source through the USB, Not just the port of the tablet.
