Owning an Honor 20 smartphone opens up a wide range of multimedia possibilities for the user, which are significantly expanded when displayed on a large screen. Modern interface The EMUI system allows you to instantly stream content, whether it's a movie from an online cinema or a presentation to colleagues. However, despite the advanced technology, setting up a wireless connection often raises questions among device owners.
The main principle of operation is the use of protocols Miracast or DLNA, which are built into the Android operating system. To get started successfully, you don't need complicated cables or adapters; all you need is a stable network. local networkIt's important to understand that image quality and the absence of lag directly depend on the data transfer speed and the router's power.
In this article, we'll take a detailed look at all the available methods for syncing your gadget with your home entertainment center. We'll cover the built-in system tools, third-party apps, and potential compatibility issues. Correct configuration network parameters will guarantee comfortable viewing of content in high definition.
Preparatory stage and network requirements
Before you begin the active setup phase, you need to make sure all components of your multimedia system are ready for use. The first and most critical requirement is that all devices are in the same location. local networkThis means that both the Honor 20 smartphone and your Smart TV must be connected to the same router.
Pay attention to the signal frequency your router broadcasts. For high-resolution video streaming, such as 4K or Full HD, it is highly recommended to use the frequency band 5 GHz. Standard 2.4 GHz may not provide sufficient bandwidth, resulting in constant buffering and audio desynchronization.
⚠️ Note: If your router supports dual-band operation, make sure that both devices are connected to the same frequency, as some older TV models may not see devices on the 5 GHz network, even if they are connected to the same router.
It's also worth checking the software version on your Honor 20. The manufacturer regularly releases security and optimization updates for the module. Wi-Fi, which can fix connection errors. Current firmware is the foundation for stable operation of all network functions.
Using the built-in Screen Projection feature
The fastest and most reliable way to display an image is to use the native system function, which is called "Screen Projection" in the Honor menu. This method is based on technology Miracast and doesn't require any additional software. The process is extremely simple and takes just a few minutes.
To get started, pull down the notification shade and find the icon labeled "Screen Projection." If the icon isn't available in quick access, tap the edit icon (usually a pencil or four dots) and drag the desired widget to the active panel. An alternative approach is through the settings menu: go to Additional functions and select the appropriate item.
☑️ Check before launching the projection
Once enabled, your smartphone will automatically search for available displays. Once your TV's name appears in the list, tap it. A connection confirmation prompt may appear on the TV screen, which you'll need to accept with your remote. Your phone's image will instantly be mirrored on the big screen.
It is important to note that when using this method, the smartphone and TV form a direct Wi-Fi Direct connection. This ensures minimal latency, which is especially important for gaming or watching fast-paced videos. However, this mode drains the phone's battery faster than usual.
Setting up DLNA via the Video app
If your goal is not screen mirroring, but viewing photos or video files stored in the smartphone’s memory, it is better to use the protocol DLNAUnlike Miracast, it doesn't put a strain on the phone's processor, as it only streams the media file, not the entire system interface. For this purpose, the Honor 20 comes pre-installed with the "Video" app.
Open the default Video app and go to the Me tab. Here you'll see a "DLNA" section or the casting icon (a rectangle with waves in the corner). Click it, and the system will prompt you to select an available device. Select your TV from the list.
Once successfully connected, the app interface will change, revealing a control panel. Now you can select any file from your phone's gallery, and it will play on your TV. You can use your smartphone for other tasks, lock the screen, or make calls—playback will continue uninterrupted.
Connecting via the TV Assist app
A special application has been developed for owners of Huawei and Honor devices. AI Life (formerly Huawei AI Life), which allows you to control smart home appliances. While its primary function is to configure routers and IoT devices, it also has functionality for interacting with TVs from certain brands.
Download the app from the store AppGallery or Google Play (if Google services are enabled on your device). After installation, run a device scan. If your TV supports Huawei protocols, it will appear in the list of available devices.
The app's functionality not only allows you to mirror your screen but also use your smartphone as an advanced remote control. You can enter text using the phone's keypad, control the volume, and change channels. This is especially convenient when the TV's built-in keypad is slow or awkward.
| Parameter | Miracast (Projection) | DLNA (Video/Photo) | AI Life app |
|---|---|---|---|
| Transmission type | Full screen mirror | Media files only | Management and broadcasting |
| Impact on battery | High | Low | Average |
| Background work capability | No (screen active) | Yes | Partially |
| Latency | Minimum | Absent | Depends on the TV model |
Troubleshooting connection issues
Despite the standardization of technologies, users often encounter a situation where the Honor 20 "doesn't detect" the TV. First, check whether the function is enabled on the router. AP Isolation (Client Isolation). When enabled, devices on the Wi-Fi network cannot communicate with each other, blocking the TV search.
The second common cause is firewall or antivirus settings on your router. Try temporarily disabling traffic filtering. Also, make sure your TV has the latest firmware update, as manufacturers frequently fix compatibility issues with new versions of Android.
⚠️ Note: Honor TV interfaces and firmware versions may vary. If the menu items described differ, please refer to your device's official documentation or check the "About" section to confirm the software version.
If the problem persists, try resetting the network settings on your smartphone. Go to Settings → System & updates → Reset and select "Reset Network Settings." This will delete saved Wi-Fi passwords and Bluetooth settings, but it often resolves device visibility issues.
Hidden reasons for lack of connection
Sometimes, antivirus software on your router blocks the ports required for DLNA (usually port 80, 8080, or 1900). The issue may also be due to an outdated Wi-Fi security standard (WEP instead of WPA2/WPA3).
Using third-party applications
Built-in tools aren't always sufficient, especially if you want to stream content from apps that block screen recording (for example, some DRM-protected online movie theaters). In such cases, third-party solutions such as Web Video Caster or BubbleUPnP.
These apps work by bypassing restrictions. You copy a video link or select a file in the app, and it sends a command to your TV to play the stream directly from the internet. In this case, your phone acts only as a remote control, saving battery life and data.
Install the selected app from a trusted source. Once launched, it will scan the network and offer a list of available receivers. Select your TV and enjoy the content. Most of these apps offer free basic functionality, sufficient for comfortable use.
Why doesn't the Honor 20 find the TV in the list of devices?
Most often, the problem is that the devices are connected to different networks (for example, one to a guest Wi-Fi network and the other to the main network) or that client isolation is enabled on the router. Also, check that Miracast/Screen Share is enabled in the TV settings, as it doesn't activate automatically on some models.
Is it possible to connect the Honor 20 to a TV without Wi-Fi?
Yes, this requires a USB-C to HDMI adapter. This will ensure the most stable connection without lag, but will require an available HDMI port on your TV and the purchase of an additional cable. Wireless connectivity is not used in this case.
Does connecting to 5GHz Wi-Fi affect picture quality?
Yes, using the 5 GHz band is critical for transmitting 4K or high-bitrate video. The 2.4 GHz band is often overloaded by neighboring routers and has lower throughput, resulting in artifacts and interruptions.
