Modern smartphones of the series Honor Mobile phones have powerful screens, but for viewing photos or videos with family, the screen size of a mobile device is often insufficient. Fortunately, wireless signal transmission technology allows you to instantly display images on a larger display without the hassle of wires. This is especially convenient when you need to share a presentation with colleagues or watch a movie from a streaming service.
The process of synchronizing devices is based on standards Miracast And DLNA, which are built into the shell EMUI or Magic UIYou won't need complicated adapters or HDMI cables if both devices are on the same network. In this article, we'll cover all available connection methods in detail, from built-in system tools to third-party apps.
Before starting the procedure, make sure your router supports the 5 GHz standard for stable high-definition video transmission. Slow network speeds can cause delays or desynchronization of audio and video. We'll cover setup details for different TV and phone models.
Technical requirements and equipment preparation
For a wireless connection to be successful, both devices must be in the same information space. This means that the smartphone Honor and Smart TV must be connected to the same access point WiFiIf you have a dual-band router, make sure both devices are operating in the 2.4 GHz or 5 GHz band, as mixing bands can sometimes block detection.
It is important to consider the version of the operating system installed on your phone. Older versions Android may have restrictions on the transfer of protected content (DRM), which will result in a black screen when playing videos in applications like Netflix or KinopoiskNew models Honor with services Google Mobile Services or your own store AppGallery are usually free of these problems.
⚠️ Note: If your TV is not a Smart TV but has an HDMI port, you will need a special adapter (such as a Chromecast or Miracast dongle) that connects to the TV and creates a signal reception point.
It's also worth checking for TV firmware updates. Manufacturers often release patches that improve protocol stability. MiracastGo to your TV's settings menu and find the "Support" or "About" section to initiate a search for new software versions.
Using Honor's built-in Cast feature
The fastest and most reliable way to mirror your screen is to use the system's native feature. On smartphones Honor It's often called "Broadcasting" or "Wireless Projection." This method requires no additional software and operates at the system kernel level, ensuring minimal latency.
To activate it, pull down the notification shade. Find the icon with the name Broadcast or Wireless ProjectionIf the icon isn't visible in the menu, click the pencil or three dots to edit the quick toggles list and drag the desired item to the panel. Once enabled, it will automatically search for available devices within range.
When the list of found devices appears on your phone screen, select the name of your TV. The TV display may prompt you to confirm the connection—use your remote to confirm. The image from your phone will instantly appear on the big screen in mirroring mode.
☑️ Check before connection
It is worth noting that in some versions of the shell Magic UI The menu may look different. If the standard path doesn't work, try going to Settings → Other connections → Screen projectionMore detailed settings can be found here, including transmission resolution and image orientation.
Setting up signal reception on different TV models
Not all TVs use the same name for their signal reception function. Depending on the brand and year of manufacture, you'll need to find the corresponding option in the Smart TV menu. Below is a table of common function names for different manufacturers.
| TV brand | Function name | Menu location | Additional actions |
|---|---|---|---|
| Samsung | Screen Mirroring | Menu → Network → Broadcast | Confirmation required on the remote control |
| LG (WebOS) | Smart Share / Miracast | Home → Apps → Screen Share | You need to launch the app on TV |
| Sony (Android TV) | Screencasting | Embedded system | Available immediately after activation |
| Xiaomi (Mi TV) | Wireless display | Applications → Miracast | Application launch required |
For TVs based on Android TV (Sony, Philips, Xiaomi) often there is no need to configure anything manually - they are visible for phones Honor By default. However, if the device isn't found, check your network security settings. Sometimes routers with the "Client Isolation" feature prevent devices from seeing each other, even when they're on the same network.
For TV owners Samsung And LG Be careful: on these models, the receiving function is often disabled by default to save resources. You'll have to open the appropriate app or menu each time before broadcasting from your phone.
Broadcasting via the Huawei Video app or third-party software
If the standard "Broadcast" feature is unstable or you only want to broadcast content from a specific app (for example, a video file from your gallery), you can use specialized software. Honor often the app is pre-installed Huawei Video or similar media players with the function DLNA.
Open a video file or launch an online movie theater. In the player interface, find the "Stream" icon (the rectangle with waves in the corner). Clicking it will display a list of available devices. Unlike full screen mirroring, the TV decodes the video stream itself, reducing the drain on your phone's battery.
Among the third-party applications available in AppGallery or Google Play, stand out LocalCast And Web Video CasterThey allow you to stream video from your browser or local storage to your TV, supporting more codec formats than the system's standard tools.
⚠️ Important: When using third-party video streaming apps, make sure they have permission to access your local network. Without this permission, the app won't be able to "see" your TV.
The advantage of DLNA app-based streaming is the ability to control playback from your phone. You can pause, rewind, or turn down the volume without interrupting the stream, unlike with mirroring mode, where any notification on your phone will appear on the TV screen.
Troubleshooting connection and latency issues
Even with proper setup, users may encounter issues such as choppy video, out-of-sync audio, or a complete loss of connection. Most often, the cause is radio channel congestion. If there are many neighboring Wi-Fi networks nearby, the signal may be interrupted.
Try switching your router to 5 GHz only. This band provides the higher data transfer speeds needed for high-definition video and is less susceptible to interference from microwave ovens and Bluetooth devices. However, it has a shorter range, so keep your phone and router relatively close.
What should I do if a black screen appears when streaming video?
A black screen with working sound usually indicates DRM-protected content. This is a form of piracy protection. Solution: Use the built-in Cast button within the app itself (YouTube, Netflix), rather than a shared screen mirror.
Another common problem is antivirus software or a firewall on the router. Some router models have security settings that block media transfer protocols. Check your router settings through the web interface (usually at 192.168.0.1 or 192.168.1.1) and ensure that the functions are enabled. UPnP And Multicast activated.
If the image is choppy, try lowering the output resolution. In the projection settings on your phone Honor Sometimes you can select the quality. Also, close background apps on your smartphone to free up CPU resources for encoding the video stream.
Technology Comparison: Miracast vs. DLNA and Chromecast
Understanding the differences between technologies will help you choose the optimal use case. Miracast Creates a direct connection between your phone and TV, broadcasting a 1:1 picture. This is ideal for gaming, demonstrating menus, or working with documents where interactivity is essential.
DLNA It works differently: the phone acts as a remote control, telling the TV which file to download and play from the network. The phone is free at this point: you can minimize the app, answer a call, or even turn off the screen, and the video will continue playing on the TV. This is the best choice for watching movies.
Technology Chromecast built-in (Google Cast) is a proprietary Google development, but is supported by many modern TVs. It combines the advantages of both methods: high quality and the ability to control it from a smartphone. Phones Honor Google services work great with this protocol.
The table below provides a comparison of key features:
| Characteristic | Miracast (Broadcast) | DLNA (Media Server) | Chromecast |
|---|---|---|---|
| Phone addiction | High (screen should be lit) | Low (you can turn off the screen) | Average |
| Picture quality | Depends on the WiFi signal | Maximum (decodes TV) | Adaptive |
| Control | Full cursor control | Playlist only | Via the app |
Is it possible to display the Honor screen on a TV without WiFi?
Yes, this is possible using a USB-C to HDMI cable. This requires a special adapter that supports the MHL protocol or DisplayPort Alt Mode. However, not all Honor models support video output via the charging port. Check your device's specifications on the official website.
Why is there no sound when screencasting?
Often, audio remains on the phone due to Bluetooth settings or the selected output mode. Check that wireless headphones are not connected to the phone. Also, in some apps (such as browsers), video audio may not automatically switch to the TV—you need to select the output device in the player itself.
Does broadcasting affect internet speed?
When using Miracast (mirroring), you may not use the internet at all, as data flows directly between devices. However, if you're streaming online video, the traffic goes through the router to your phone and then to your TV, which doubles the load on the WiFi channel and can reduce speeds for other devices.
How do I turn off the broadcast?
To terminate the connection, simply unlock your Honor phone and press the disconnect button or select "Disconnect" in the "Broadcast" menu. You can also simply turn off WiFi on your smartphone, although this will also interrupt network access.
