Modern smartphones such as Honor 9, have powerful displays, but for the full viewing experience of movies or presentations, you often want to see the image on a larger screen. Fortunately, wireless data transmission technologies make it easy to stream content without unnecessary wires. Device owners Huawei And Honor can use built-in system functions that do not require the installation of additional software.
The basis for image transmission is a standard home network. WiFiIt provides sufficient bandwidth for streaming high-definition video. It's important to understand that image quality directly depends on the stability of the router's signal and the TV's support for the relevant protocols. In this article, we'll cover all the available methods for connecting your smartphone to your TV.
Before you begin setup, make sure both devices are working properly. Smartphone Honor 9 supports current wireless standards, making the connection process as simple as possible. We'll look at how the system's native tools EMUI, as well as specialized applications for older TV models.
Technical requirements and network preparation
The foundation of successful streaming is a properly organized local network. Both devices—the smartphone and the Smart TV—must be connected to the same access point. If you have a dual-band router, make sure the devices aren't on different frequencies, although modern routers typically combine them into a single logical network.
Connection stability is critical to transmitting a video stream without delays and artifacts. Protocol Miracast, which is often used for screen mirroring, is very sensitive to interference. If there are many neighboring networks in the air, the signal may be interrupted, leading to audio and video being out of sync.
⚠️ Important: If your router is using a guest network, connect your devices to the main network. Guest modes often isolate clients from each other, making it impossible for your phone to detect your TV.
It's also worth checking the software versions. Honor 9 It is advisable to update the system to the latest available version via the settings menu. Manufacturers regularly release patches that improve compatibility with various TV models and fix protocol errors. DLNA.
Using the built-in Wireless Projection feature
The most direct way to display an image from Honor 9 on the TV screen - using the system's native function. In the shell EMUI It's called "Wireless Projection." This method is based on technology Miracast, which allows for real-time video streaming without the compression typical of some streaming applications.
To activate the feature, pull down the notification shade. In the quick settings panel, find the icon labeled "Projection" or "Wireless Projection." If the icon isn't visible, tap the edit button (usually a pencil or square with a pencil) and drag the desired item to the active panel. Once enabled, the phone will begin searching for available devices within range.
On the TV, you also need to activate signal reception mode. This feature may be called "Screen Mirroring," "Screen Casting," "Mirroring," or "Cast" in the Smart TV menu. Once the TV appears in the list on your smartphone, tap it to pair it.
☑️ Check before connection
During the connection process, you may be asked to confirm with a code. This is a standard security procedure to prevent unauthorized access to your screen. After confirmation, the display image Honor 9 The image will be fully copied to the large screen. Please note that in this mode, the phone can operate in landscape or portrait orientation, scaling the image to fit the TV matrix.
Broadcast via YouTube app and streaming services
If your goal is to watch video content, rather than duplicate the entire smartphone interface, it is more convenient to use the built-in broadcast function in applications. YouTube, Netflix and other popular platforms use the protocol Google Cast or its equivalent. This allows the phone to act as a remote control while the TV downloads video directly from the internet.
This approach has a significant advantage: it does not load the processor. Honor 9 and doesn't drain battery as much as full screen mirroring. Video is buffered by the TV itself, ensuring smoother playback even with an unstable signal between the phone and the router.
To start broadcasting, open the application, for example, YouTube, on your smartphone. In the upper right corner or at the bottom of the interface, find the "Cast" icon (a rectangle with WiFi waves in the corner). Click it and select your TV from the list. It's important that the accounts on both devices are synced or simply on the same network.
What should I do if the broadcast icon doesn't appear?
If the Cast icon isn't visible, check that the YouTube app is updated to the latest version. Also, make sure the YouTube app is running on your TV or is accessible in the Smart Hub menu. Sometimes you need to restart your router for the devices to "see" each other again.
It's worth noting that using this method, the phone's screen can be used for other tasks, such as messaging, browsing, or gaming. Videos on the TV will play independently. However, some content-protected movies may block display through third-party apps due to privacy policy. DRM.
Using DLNA technology for multimedia
Protocol DLNA (Digital Living Network Alliance) is a standard that enables the sharing of multimedia content between devices within the same network. Unlike Miracast, which streams a screen video, DLNA is designed for transferring specific files: photos, music, and videos stored in memory. Honor 9.
To use this feature, the appropriate service must be running on your TV (often built into the system and called "Media Server" or something similar). On your smartphone, you can use a standard player or file manager. Open the video file, click the "Stream" button (or the triangle icon), and select your TV.
| Characteristic | Miracast (Projection) | DLNA (Media) | YouTube Cast |
|---|---|---|---|
| Transmission type | Full screen mirroring | File transfer | Streaming link |
| Phone addiction | High (screen on) | Medium (player active) | Low (can be folded) |
| Quality | Depends on the WiFi signal | Original file | Adaptive (up to 4K) |
| Sound | Transmitted with video | Transmitted with video | Transmitted with video |
Using DLNA is especially convenient if you have a collection of video files on your phone that you want to show on the big screen without first copying them to a flash drive. Data transfer speed on a local network WiFi Typically allows you to play high-definition content without buffering.
Third-party screen mirroring apps
In some cases, built-in tools Honor 9 may not be able to find the TV, especially if it is an older Smart TV model or a specific brand such as Philips or ToshibaThis is where third-party applications come in handy, implementing their own search and connection algorithms.
One of the popular solutions is the application TV Cast or similar software. They scan the network, find devices, and offer several connection modes. Some can emulate a signal compatible with specific TV models. Installing such software can be a lifesaver if your standard projection system is unstable.
⚠️ Please note: When using free versions of third-party apps, be prepared for ads. Additionally, some features, such as 4K video transfer or the removal of watermarks, may only be available in paid versions.
Another option is to use intermediary applications that are installed on the TV (if it is based on Android TV), and on the phone. An example is AirScreen or ApowerMirrorThey create a virtual bridge, providing a more stable connection and allowing you to control your phone with your TV remote, although for Honor 9 This may require system permissions.
Solution and troubleshooting
Even with proper setup, problems can still occur. A common situation is when the phone sees the network but can't find the TV. In this case, the first thing to do is reboot the router. This will clear the DHCP server cache and refresh the list of connected devices, which often resolves the "invisibility" issue.
Another common problem is audio and video desynchronization. This almost always indicates channel congestion. WiFiTry switching your router to a less crowded frequency (for example, from 2.4 GHz to 5 GHz, if your TV supports this range). Honor 9 Works great with both ranges.
If the image is choppy or has low resolution, check the screen resolution settings in the projection menu. Sometimes the system automatically selects a resolution that is too high for your router to handle without loss. Reducing the quality to 720p can dramatically improve smoothness.
Frequently Asked Questions (FAQ)
Is it possible to stream the Honor 9 screen to a TV without a WiFi router?
A direct WiFi Direct connection is possible if your TV supports this feature and allows you to connect your phone directly without going through a router. However, for most services (YouTube, online movie theaters) to work reliably, an internet connection is still required.
Why is there only a picture but no sound?
This could be due to DRM restrictions in some apps or incorrect audio settings in Android. Check that "Video Only" mode isn't selected in the projection settings. Also, try increasing the volume on your phone itself, as sometimes the audio doesn't automatically switch to the output device.
Does broadcasting affect internet speed at home?
Yes, screen mirroring and video streaming consume a significant amount of WiFi bandwidth. If you're watching a 4K movie from your phone to your TV, other devices on the network may have difficulty loading pages or playing online games.
Does the Honor 9 support Bluetooth audio streaming to TV when casting?
When using Miracast, audio is transmitted along with the video stream via WiFi. Bluetooth is typically not used to transmit audio to the TV in this setup, as Bluetooth bandwidth is insufficient for synchronous, high-quality video. If the TV doesn't support the Miracast audio channel, there may be no audio.
