The process of synchronizing devices is based on technology Miracast or proprietary solutions from the manufacturer, such as Google Chromecast built-in. Both devices must be on the same local Wi-Fi network to successfully transmit the video stream. Xiaomi device owners often encounter shell nuances MIUI, where the broadcast functions may be named differently depending on the firmware version.
In this article, we'll take a detailed look at all available connection methods, from built-in system tools to third-party applications. You'll learn how to set up wireless display, which apps are best for streaming, and what to do if your TV doesn't detect your phone. A thorough network setup and understanding of how protocols work will help you avoid common mistakes.
Preparatory stage and checking network settings
Before starting the active setup phase, you need to make sure that your home network infrastructure is ready to transmit a heavy video stream. Connection stability — a key factor affecting the absence of lag and image artifacts. Make sure the router is working correctly and assigning IP addresses to both devices.
It is critical that the smartphone Xiaomi and Smart TV TCL were connected to the same access point. If your router broadcasts two networks (2.4 GHz and 5 GHz), it is advisable to use the range 5 GHz to achieve maximum throughput. In some cases, frequency separation may have different network names; check this in your router settings.
It is also worth checking if the function is enabled Wi-Fi Direct or similar device discovery services on the TV. In the TCL menu, these are often hidden under the network connections section. Without these services enabled, the phone simply won't be able to "see" the TV in the list of available devices for casting.
⚠️ Note: If you have configured Guest Network mode for Wi-Fi, devices may be isolated from each other. In this mode, streaming to your TV will not work, as the router blocks local traffic between clients.
Updating your software is another important step. Check for system updates. Android TV on TV and for the shell MIUI on a smartphone. Manufacturers often release patches that fix protocol errors. DLNA And Miracast, which directly affects the stability of the connection.

The easiest and fastest way to display an image is to use the system's native function. On smartphones Xiaomi And Redmi It's called "Broadcast" or "Wireless Monitor." This method doesn't require any additional software and works at the system level.
To activate, pull down the notification shade and find the "Broadcast" icon. If it's not on the home screen, tap the pencil or three dots to edit the quick access panel. Once enabled, it will automatically search for available receivers on your local network.
When your TV's name appears on the screen TCL, tap it. The image from your phone will instantly appear on the big screen. In this mode, the full mirroring, that is, everything that happens on the smartphone screen is visible on the TV, including notifications and desktops.
☑️ Check before starting the broadcast
It's worth noting that image quality depends on the radio channel load. If you notice audio and video desync, try closing background apps on your phone that are consuming internet traffic. Also, this feature may not work with protected content (DRM) from some streaming services due to security policies.
Using Google Chromecast technology
Most modern televisions TCL run on an operating system Android TV or Google TV, which implies built-in support for the technology ChromecastThis is a more advanced streaming method that allows you to transmit content directly from apps, bypassing the smartphone screen.
Unlike simple mirroring, here your phone acts as a remote control. You open a video in an app (such as YouTube or Netflix), tap the rectangle icon with waves, and select your TV. The video stream is sent directly from the server to the TV via Wi-Fi, saving your phone's battery.
