Modern Honor smartphones feature powerful displays and cameras that allow for the creation and consumption of high-quality content, but the screen size of a mobile device is often insufficient for watching group videos or analyzing photos in detail. Wireless technology allows for instant streaming of media content to a large screen, transforming a regular TV into a multimedia center without the hassle of cables.
In this article we will examine in detail all the available methods. screen broadcasts and file transfer, focusing on the features of the Android operating system and Magic UI. You'll learn the nuances of the Miracast and DLNA protocols, and get answers to questions that arise when connecting to TVs of various brands.
It's worth noting that the success of the connection directly depends on the stability of your local network and the software version on both devices. Menu interfaces may vary slightly. It depends on the specific smartphone model and year of TV production, but the basic principles remain the same across the entire ecosystem.
Preparing equipment and network for work
The first and most critical condition for stable wireless data transmission is that both devices are on the same local network. Your smartphone Honor and the TV must be connected to the same router, otherwise they simply “will not see” each other in the list of available devices.
Make sure AP Isolation isn't enabled on your router, as this security feature specifically blocks communication between devices within the network. It's also recommended to use the 5 GHz band if your router supports dual-band operation, as it provides higher throughput for the video stream.
Make sure your TV has Smart TV enabled or the appropriate Wi-Fi module installed. Some older models may require manual activation of Screen Share or Miracast in the app menu.
⚠️ Attention: If your router distributes two networks (2.4 GHz and 5 GHz) with different names, make sure that both the phone and TV are connected to exactly one of them, even if they are on the same subnet.
Before starting setup, update the Projector or Broadcast app on your smartphone via the AppGallery or Google Play store, if available. This will avoid compatibility issues with new protocol versions.
Miracast wireless projection method
The most common way to display an image from an Honor phone on a TV screen is to use technology Miracast, which is built directly into the operating system. On Honor smartphones, this feature is often called "Wireless Projection" or "Screen Projection" and does not require any additional software.
To activate it, pull down the notification shade and look for the "Projection" or "Wireless Projection" icon. If it's not visible, tap the edit icon (usually a pencil or four dots) and add the toggle to the active panel.
Once enabled, your phone will begin searching for available devices. On your TV, open the app responsible for signal reception. This app may have different names depending on the brand:
- 📺 Samsung: Screen Casting or Smart View app.
- 📺 LG: Screen Share application.
- 📺 Sony/Philips: Enter signal sources (Inputs) -> Miracast or just wait for connection.
- 📺 Xiaomi/Redmi: “Mi Wireless Display” application.
Once the TV appears in the list on your smartphone screen, tap it. The connection process will take a few seconds, after which the image from your phone will be fully copied to the big screen.
It's important to understand that when using Miracast, the phone and TV screens are fully synced. This means any notifications, incoming calls, or messages will be visible to everyone in the room.
☑️ Check before connection
Using DLNA technology for media files
If your goal is not screen mirroring, but viewing photos, videos or listening to music stored in the phone’s memory, then the technology DLNA It's perfect. It allows you to stream a specific file without overloading your phone's processor with the system interface.
To use this method, your TV must have a DLNA-compatible receiver app installed (often built into Smart TVs), while on an Honor phone, the standard Gallery or Video app is sufficient. Open the desired file, click the "Cast" button (the triangle icon in a rectangle), and select your TV.
The advantage of DLNA is that you can minimize an app or even lock your smartphone's screen, and playback on your TV won't be interrupted. This frees up your mobile device for other tasks.
| Characteristic | Miracast (Projection) | DLNA (Streaming) |
|---|---|---|
| Transmission type | Full screen mirroring | Media files only |
| Impact on the phone | The screen is active, battery consumption is high | The screen can be turned off, consumption is lower |
| Interface | Visible on TV | Hidden, only content is visible |
| Delay | Possible (depending on the router) | Minimum |
Some third-party video players such as VLC for Android or MX Player, have more advanced algorithms for searching DLNA devices and can better handle "heavy" video formats that the standard gallery cannot read.
Apps from TV manufacturers
Major TV manufacturers often develop their own ecosystems that provide a more stable connection and expanded functionality compared to standard Android protocols. For Honor owners, using the brand's proprietary TV app often solves audio and video out-of-sync issues.
For example, for Samsung TVs, the optimal solution would be an app SmartThingsAfter installation and authorization, it automatically finds your TV on the network. Select "Smart View" from the app menu, which allows you to not only mirror your screen but also use your phone as a remote control.
LG TV owners should pay attention to the app LG ThinQ or "LG TV Plus." These apps allow you to stream photos and videos from your Honor gallery to your TV, as well as control playback. The interface of these apps is typically more user-friendly than the standard Android menu.
⚠️ Attention: When installing third-party apps from TV manufacturers, carefully check the requested permissions. Access to the gallery and microphone is necessary for operation, but access to contacts or SMS is often unnecessary.
For Sony TVs running Android TV, a separate app may not be required, as the system is deeply integrated with Google services. However, the app Video & TV SideView can add remote control and program scheduler functionality.
What should I do if the app doesn't detect the TV?
Make sure your router doesn't have a guest network. Guest networks are often isolated from the main network, so a phone on the guest Wi-Fi won't be able to find a TV connected to the main network. Switch both devices to the main network.
Streaming via Google Home and Chromecast
If your TV has a built-in module Chromecast Or if you're using an external set-top box with this functionality, the most reliable way is to use the Google Home app. This is Google's official tool, which works on all smartphones with Google Play services.
After installing the Google Home app and setting up your device (if it's new), you can tap the "Cast Screen" button in the app menu. This will ensure the most stable image transmission with minimal latency, as the protocol is optimized by the OS developer.
Many modern video streaming apps (YouTube, Netflix, IVI) have a built-in Chromecast button. By clicking this icon inside the video player, you can start playback directly on your TV, using your phone only as a remote.
The advantage of the Google Home method is its high-resolution support and adaptive bitrate, which reduces the likelihood of image freezing on unstable internet connections. However, a Google account and an active Google session are required.
Troubleshooting connection and latency issues
Even with proper setup, users may encounter problems: the image flickers, the audio lags behind the video, or the connection constantly drops. Most often, the cause is radio congestion or a weak signal.
Try rebooting your router by unplugging it for 10-15 seconds. This will clear the device's memory buffer and force it to select a less crowded Wi-Fi channel. Also, check that your phone isn't too far from the router.
If the issue only occurs with certain apps, try clearing the cache for the Projector or Cast app in your phone's settings. To do this, go to Settings → Applications → Projection → Storage → Clear cache.
In some cases, disabling Bluetooth on your smartphone while broadcasting can help, as operating in the 2.4 GHz band can interfere with the Wi-Fi signal if your router also operates on this frequency.
⚠️ Attention: Menu interfaces and item names may be changed by manufacturers in software updates. If you can't find an exact match, look for synonyms or similar icons.
Frequently Asked Questions (FAQ)
Why isn't my TV showing up in the list of available devices?
Most likely, the devices are on different networks (for example, one on a guest network and the other on the main network) or client isolation is enabled on the router. Also, check if the TV requires connection confirmation (pressing the "Accept" button on the remote).
Is it possible to transmit an image if there is no internet, only a local network?
Yes, Miracast and DLNA don't require internet access; the router simply needs to create a local network to which both devices are connected. Some TVs can create a Wi-Fi Direct hotspot, which the phone can connect to without a router.
Why is there no sound when watching a video from my phone on TV?
Check the audio settings in the app you're streaming from. Sometimes the audio remains on your phone. Also, make sure your TV isn't set to "Mute" and the volume is turned up. In rare cases, restarting the source app helps.
Does transferring images to an Honor phone affect its battery?
Yes, wireless projection is power-intensive, as it involves the Wi-Fi module, processor, and screen. It's recommended to keep your phone charged or monitor its battery level to prevent it from shutting down mid-movie.
Do all Honor TVs support Magic Cast?
Honor Magic Cast technology (or similar names in newer models) works with most modern Smart TVs that support Miracast and DLNA protocols. Older models may require the purchase of an external set-top box.
