Preparatory stage and network requirements
Before setting up the broadcast, you need to ensure that both devices are in the same network environment. This is a basic requirement, without which hardware detection is simply impossible. Both devices must be connected to the same network. WiFi networks, be it a home router or a mobile hotspot.
⚠️ Important: If your router supports dual-band mode (2.4 GHz and 5 GHz), make sure your laptop and TV are connected to the same frequency. Sometimes devices on different frequencies cannot see each other due to client isolation settings on the router.
Check that your TV's firmware is up to date, as older firmware versions may not support modern video encoding standards. Go to your TV's settings menu. TCL, find the "System" or "About TV" section and select "Check for updates." Having the latest software ensures known bug fixes and improved protocol stability. Miracast And DLNA.
It's also worth paying attention to your wireless network signal. If the router is in another room or behind thick walls, the data transfer rate may be insufficient to stream high-definition video. Ideally, the distance between the access point and the receiver should be minimal to ensure a smooth picture without stuttering or buffering.
Mirror your screen using Miracast (Windows 10 and 11)
The easiest and fastest way, which does not require installing additional software, is to use technology Miracast, built into Windows 10 and 11 operating systems. This protocol allows you to mirror your screen or extend your desktop onto a TV, creating the effect of a second monitor. To get started, make sure the "Wireless Display" feature is enabled on your TCL TV.
On the remote control, press the Home or Menu button, then go to the apps section. Find the app named Wireless Display, Mirkast or T-Connect (The name may vary depending on the model and region.) After launching the app, a message will appear on the screen indicating that a connection is pending, and the device will become discoverable.
Now let's move on to the laptop settings. Press the key combination Win + K on your keyboard to open the "Connection" panel. Your TV should appear in the list of available devices. Click it, and after a few seconds, the image from your desktop will appear on the big screen.
Miracast Connection Checklist
It's important to note that this method may cause a slight mouse cursor lag, which is normal for wireless technologies. If you plan to work with text or watch videos, the delay won't be noticeable. However, for fast-paced games, this method may be less preferable due to latency.
Using DLNA to play media files
If your goal is not to duplicate the desktop, but to play specific video files, photos or music stored on your hard drive, then it is better to use the protocol DLNAThis method is less resource-intensive and ensures more stable playback of heavy content, since the TV decodes the stream itself rather than receiving a pre-programmed image from the screen.
To implement this method on a Windows laptop, you need to set up folder sharing. Open Settings (you can do this via Start → Settings), go to "Network & Internet," then select "Sharing Options." Turn on network discovery and file and printer sharing for your current network.
After that, find the folder with your media files, right-click it, and select "Share with" → "Specific people." Add the "Everyone" user with read access. Now, launch the built-in app on your TCL TV. Media player or My files, select the "Network" or "DLNA" source and you will see your computer in the list of devices.
| Protocol | Purpose | Delay | Quality |
|---|---|---|---|
| Miracast | Screen mirroring | Medium/High | Depends on the signal |
| DLNA | Viewing files | Absent | Original |
| Chromecast | Broadcast from a browser | Low | High |
| HDMI (cable) | Universal | No | Original |
It's important to note that DLNA doesn't allow you to manage Windows windows or share the desktop. It's purely a media server. If you need to show a PowerPoint presentation in editing mode, this method won't work, but for watching a movie from a folder, it's the optimal solution.
Broadcasting via Google Chrome (Chromecast built-in)
Many modern TCL TV models operate on the platform Android TV or have built-in support for the technology Google CastThis allows you to use the Google Chrome browser on your laptop as a TV remote control. This method is especially convenient if you want to display the contents of a specific tab or the entire screen.
Open the Chrome browser on your computer. Make sure you're signed in to your Google account (this isn't always required, but it's recommended). Click the three dots in the upper-right corner of the browser (the menu) and select Broadcast... (Cast). The browser will begin searching for available devices on the network.
In the window that opens, you'll see a list of sources. You can select "Cast Tab" to show a specific website or "Cast Screen" for full mirroring. Click the name of your TCL TV, and the content will begin playing on the big screen. Playback controls (pause, volume) are available directly from the browser interface.
The advantage of this method is its cross-platform compatibility: it works equally well on Windows, macOS, and Linux. Furthermore, Google Cast often provides better stream stabilization than native Miracast, especially when watching YouTube videos or other streaming services directly from the browser.
Solving common connection problems
Despite their apparent simplicity, wireless technologies can encounter interference and software conflicts. If your laptop can't detect your TV or the connection keeps dropping, first check your computer's WiFi adapter drivers. Outdated drivers often don't work correctly with new encryption and media transfer standards.
Another common cause of problems is firewall or antivirus settings. They can block incoming connections required to establish a handshake between devices. Try temporarily disabling protection or adding your home network to the list of trusted (private) networks in Windows settings.
⚠️ Note: Menu interfaces and item names may vary slightly depending on the TV's year of manufacture and the version of the TCL operating system (Google TV, Android TV, or Roku TV). Always consult the official documentation for your specific model if you cannot find the function described.
If the image is choppy or low-resolution, try reducing the bandwidth usage. Close torrents and other bandwidth-hungry programs. It's also a good idea to switch your router to a less congested WiFi channel, especially if you live in an apartment building with multiple neighboring networks.
Alternative applications and third-party software
When built-in tools are unstable, specialized apps can help. For Android TVs (often found on TCL), you can install an emulator on your laptop or use client programs. A popular solution is to use streaming apps such as LetsView or ApowerMirror.
These programs often offer more flexible settings, such as the ability to control your computer from the TV screen (if a mouse/keyboard is connected to the TV) or screen recording. Setup is usually simple: download the app on your PC and the corresponding app from the Google Play store on your TV, then scan the QR code to pair.
However, it's worth remembering that third-party software may be paid or contain ads. Free versions often have session time or image quality limitations. Therefore, using native Windows and Android features is always preferable for basic tasks.
Frequently Asked Questions (FAQ)
Why isn't my TCL TV showing up in the list of available devices?
Most often, the problem is that the devices are connected to different networks (for example, one to the router's guest network and the other to the main network). Also, make sure the appropriate signal-receiving app (Miracast/Cast) is running on your TV, as some models don't constantly scan the network in the background to save power.
Is it possible to connect a MacBook to a TCL TV wirelessly?
Yes, it's possible, but not all TCL models support AirPlay directly. If your TV doesn't have built-in AirPlay 2 support, you'll need to install a third-party app on Android TV (such as AirScreen) or use the Chrome browser to cast a tab, as described above.
Is there any audio delay when connected via WiFi?
Minor audio and video sync issues are possible, especially when using Miracast. Your TV's settings often include an "Audio Delay" or "Audio Sync" option that allows you to manually adjust this setting. When using DLNA for file playback, such issues usually don't occur.
Do you need internet to connect a laptop to a TV?
The image transfer process itself doesn't require internet access; a local WiFi network is sufficient. However, if you're streaming online video (YouTube, Netflix), internet access is, of course, necessary. Some Smart TV features may require initial network authorization.
