Using the built-in Screen Mirroring (Miracast) feature
The most versatile way to broadcast your screen is by using technology Miracast, which is built into most TCL Android TVs. This feature allows you to mirror your smartphone's image to your TV in real time without installing any additional software. The protocol works directly between devices, creating a direct Wi-Fi connection.
Activating the mode on your TV often requires no action if the feature is enabled by default. However, on some models, you may need to manually launch the app. Wireless Display or Screen Mirroring in the app list. After this, the TV will go into connection standby mode.

|---|---|---|---|
| Platform | Android / Windows | Android / iOS / PC | iOS / macOS |
| Phone CPU usage | High (encodes video) | Low (control only) | Low |
| Quality | Depends on the signal | High (up to 4K HDR) | High |
| Work in the background | No (screen active) | Yes | Yes |
The advantage of this method is the ability to control playback from other devices on the same network. You can pause a video while you're in the kitchen and then continue watching later. Casting Chrome browser tabs from a computer is also supported, as long as it's on the same Wi-Fi network.
Connecting Apple devices (AirPlay 2)
iPhone and iPad owners can take advantage of the technology AirPlay 2, which is natively supported by modern TCL models. This ensures seamless integration of the Apple ecosystem with the TV. The image is transmitted in high quality with minimal latency, and the sound can be streamed to a connected HomePod speaker system.
To activate the feature on a TCL TV, you need to go to Settings and make sure AirPlay is enabled. It's usually located in Settings → System → Apple AirPlay and HomeKitHere you can also set up security requirements, such as requiring a code upon first connection.

⚠️ Attention: AirPlay may not be available on older TCL TV models released before AirPlay support was implemented. In this case, you will need to use third-party emulators.
A key feature of AirPlay 2 is its ability to sync media. You can listen to music on your TV while in another room, or use Siri to control playback. Voice commands work effectively if the TV is connected to the same iCloud account or configured accordingly.
What should I do if AirPlay doesn't detect my TV?
Make sure AP Isolation isn't enabled on your router. Also, check that your firewall isn't blocking the ports required for Bonjour/mDNS protocols (usually port 5353).
Stream via the TCL Home (T-Cast) app
Official app TCL Home (formerly known as T-Cast) offers advanced TV control and content streaming capabilities. It not only allows you to mirror your screen but also stream media files (photos, videos, music) from your phone directly to your TV. It's a convenient way to share a family album or play a locally stored movie.
Download the app from Google Play or App Store and start a network scan. The program will find your TV and offer pairing. Unlike system methods, this interface is tailored specifically to TCL features, simplifying navigation through the smartphone's file system.
- 📂 Select content type: Photo, Video, or Music.
- 📱 Select the file to play from the list.
- ▶️ Click the connect to TV button in the app interface.
The app also lets you use your phone as a full-fledged keyboard for text entry, which is especially convenient when searching for videos on YouTube or Netflix on your TV. Typing via the smartphone's virtual keyboard is much faster than navigating the on-screen keyboard with the remote.
Solution and troubleshooting
Even with proper setup, technical difficulties may arise. Most often, problems are related to an unstable Wi-Fi signal or outdated software. If the TV isn't visible in the list of available devices, try a full reboot: unplug the TV from the power outlet for 10 seconds, then plug it back in.
Another common cause is the use of different Wi-Fi frequencies. If the router broadcasts two networks (2.4 GHz and 5 GHz) with different names (SSIDs), make sure both devices are connected to the same one. Mixing networks can sometimes prevent devices from being detected by DLNA and Cast protocols.
adb shell settings put global development_settings_enabled 1For advanced users experiencing lag issues while gaming or watching, changing the DNS servers in the TV's network settings can help. Using public DNS servers, such as Google (8.8.8.8) or Cloudflare (1.1.1.1), often speeds up system response and improves streaming stability.
If none of these methods work, check the date and time on your TV. An incorrectly set time can cause security certificate errors, which will cause secure data transfer protocols (HTTPS) to block the connection.
Frequently Asked Questions (FAQ)
Why is there no sound when streaming video from my phone to TCL?
This may occur if the source app doesn't support audio transmission via Cast, or if the wrong sound mode is selected on the TV. Try changing the audio output settings in the TV menu or use the screen mirroring mode (Miracast), which transmits system audio.
Is it possible to broadcast a screen if there is no internet access, only a router?
Yes, local streaming (Miracast, DLNA) doesn't require internet access. It's enough for the router to create a local Wi-Fi network and for both devices to be connected. However, Google Cast and AirPlay may require internet access for initial authorization.
How to reduce image lag when streaming games?
The ideal solution is to use Game Mode on your TV, if available. It's also recommended to connect the TV and router via an Ethernet cable and use the smartphone on the 5 GHz band. Miracast typically offers lower latency than Chromecast because it doesn't buffer the stream.
The TCL TV stopped detecting the phone after updating the router.
It's likely that the security settings or network name changed after updating your router. Go to the Wi-Fi settings on both devices, select "Forget Network," and reconnect using the password. This will update the network licenses and permissions.
