How to connect Xiaomi phone to TCL TV via Wi-Fi: all working methods

Wirelessly streaming your smartphone screen to a TCL big screen over Wi-Fi offers a range of possibilities, from watching high-resolution movies to showing presentations or running mobile games on a wide display. However, Xiaomi users often face compatibility issues — not all TCL TV models work equally well with Miracast protocols, DLNA or branded solutions like Xiaomi Screen Mirroring. In this article, we will discuss all the current ways of connecting with the features of MIUI 14/15 firmware and TCL TVs on Android TV or Roku OS, and give recommendations for eliminating typical errors.

The main difficulty is that TCL uses different operating systems depending on the model and year of release: old TVs run on Roku TV, new ones run on Android TV or Google TV. Xiaomi smartphones (such as the Redmi Note 12 or POCO X5 Pro) support several wireless transmission protocols, but not all of them are compatible with TCL out of the box.

1. Device Preparation: What to Check Before Connecting

Before trying to connect Xiaomi and TCL, make sure both devices meet the minimum requirements:

• 📱 Smartphone Xiaomi: version MIUI 12 or later (older firmware may not support Miracast). → The phone.
• 📺 Television TCL: The model supports Wi-Fi Direct, Miracast or DLNA. On the box or in the menu (Settings) → Network) should be marked about wireless broadcasting.
• 🔄 Shared Wi-Fi network: Both devices must be connected to the same network (except for Wi-Fi Direct, where the network creates the TV itself).
• 🔋 Battery charge: the smartphone should be at least 30% of the charge – broadcasting the screen actively consumes energy.

Pay special attention to TV firmware: Outdated versions of TCL software (especially on 2019-2020 models) may not support modern protocols. Update TV through Settings → Support → Software Update. If no updates, use alternative connectivity methods (see section 4).

⚠️ Attention: On TVs TCL rogue OS (for example, series 3-Series or 4-Series) Screen Mirroring can be disabled by default. Activate it in Settings → System system → Screen mirroring.

Method 2: Screen Mirroring by Miracast (Native Method)

Miracast is a wireless screen broadcast standard supported by most modern devices, and on Xiaomi smartphones it is implemented through the Wireless Display feature, and on TCL TVs via Screen Mirroring or Wi-Fi Display.

Instructions for connection:

1. On TCL, open Settings → Network → Screen Mirroring (or Wi-Fi Direct) and remember the name of the device that appears on the screen (e.g. TCL-55C715).
2. On a Xiaomi smartphone, go to Settings → Connections and Sharing → Wireless display.
3. Turn on the Wireless Display slider and wait until the name of your TV appears on the list.
4. Confirm the connection on both devices (entry may be required) PIN-TV-code).

If the connection fails, check:

• 🔌 Both devices are connected to the same Wi-Fi network (or the TV has created its own access point).
• 🔄 Device Detection mode is enabled on the TV (in some models) TCL It needs to be manually activated).
• 📵 On the smartphone, the mode Saving the battery is turned off - it can block background processes.

3. Method 2: Using Google Cast (for Android TV)

If your TCL TV is running on Android TV or Google TV (models 5-Series, 6-Series, C-Series and later), you can use the Google Cast protocol. It allows you not only to duplicate the screen, but also to stream individual applications (for example, YouTube or Netflix) directly to the TV.

Step-by-step:

1. Make sure that your TV and smartphone are connected to the same Wi-Fi network.
2. On your TV, open the Google Home app (if not, install it from the Play Market on TV).
3. On a Xiaomi smartphone, install the Google Home app (if not already installed) and log in.
4. In the Google Home app on your phone, tap the Cast icon (in the upper right corner) and select your TCL TV.
5. To duplicate the screen, select Translate screen, to transfer content from the application (for example, video) – just run it, and the Cast icon will appear in the player.

Advantages of this method:

• 🎮 Support for audio broadcast only (good for music).
• 📺 The ability to continue using the phone while broadcasting (unlike Miracast, where the screen is completely duplicated).
• 🔄 More stable connection compared to Wi-Fi Direct.

⚠️ Note: On some models TCL rogue OS Google Cast may not be available, in which case use method 1 (Miracast) or method 4 (third party applications).

4. Method 3: DLNA/UPnP for transferring media files

DLNA does not duplicate the screen of a smartphone, but allows you to broadcast photos, videos and music from a gallery or file manager to a TCL TV, which is suitable if you do not need to mirror the screen, but only watch media.

How to set up:

1. On TCL, turn on the DLNA or Media Server function (path: Settings → Network → Home Network).
2. On a Xiaomi smartphone, install a DLNA management app, such as: BubbleUPnP (for power users), LocalCast (a simple interface), Xiaomi File Manager (built-in DLNA support in MIUI).

Limitations of the method:

• 🚫 No screen duplication – only transfer of individual files.
• 🎵 Not all video formats are supported (e.g..mkv may not play).
• 📶 Quality depends on the speed of Wi-Fi – with a weak signal, slowdowns are possible.

5. Method 4: Third-party applications

If standard methods don’t work, use specialized applications that often offer additional features, such as high-resolution broadcasting or support for game controllers.

Top.-3 Proven applications for Xiaomi:

• 📱 ApowerMirror - supports screen mirroring with minimal latency, there is a Game Mode for gamers.

Instructions for ApowerMirror:

1. Run ApowerMirror on both devices and select Phone Screen Mirroring mode.

⚠️ Note: When using third-party apps, disable Battery Optimization for them in Xiaomi settings (Settings) → Annexes → Permits → Auto-start, otherwise the connection may be interrupted.

💡

If the broadcast slows down, reduce the screen resolution in the app settings (for example, from 1080p to 720p) and this will reduce the load on the network and the smartphone processor.

6. Resolve connection errors

Even with the right setup, there can be problems, and let's look at the most common mistakes and their solutions.

If none of the methods worked:

1. Reboot both devices.
2. Reset the network settings on the TV (Settings → System → Network Reset).
3. Try connecting via USB-OTG (if the TV supports MHL).

💡

On TCL TVs with Roku OS, before connecting to Miracast, be sure to turn off the Bandwidth Saver feature in network settings – it limits data transfer speed and can block broadcasting.

7. Optimization of broadcast quality

To make the picture on the TV clear, and the sound synchronous, follow these recommendations:

• 📶 Use 5GHz Wi-Fi instead of 2.4GHz – this will reduce latency and improve stability.
• 🔌 Connect the TV to the router via Ethernet cable (if there is a port), and leave the smartphone on Wi-Fi.
• 🎛️ In the broadcast settings (for example, in ApowerMirror) select: 1080p (for films or 720p (Frequency of frames: 60 FPS (Bitrate: 10–15 Mbps (optimum for most networks).
• 🔇 Turn off background apps on your smartphone that consume the internet (such as downloads or cloud syncs).

For gamers:

• 🎮 Turn on Game Mode on your TV (Settings) → Picture → Image mode).
• 🕹️ Use a gamepad connected to your smartphone via Bluetooth – so the delay will be less than when controlling the sensor.
