The question of how to output video from a phone to a TV via WiFi becomes especially relevant when you want to show off vacation photos or watch a movie on a big screen without the hassle of wires. Fortunately, wireless data transfer technologies make this possible in minutes using built-in wireless projection protocols.
Unlike older methods with HDMI cables, wireless connection gives you complete freedom of movement. Wireless projection at the base Miracast or technology DLNA Built into the EMUI shell, this significantly simplifies the process for the user. You don't need to look for special adapters or navigate complex network settings if both devices are on the same local network.
However, there are many nuances that can affect image quality and connection stability. In this article, we'll detail all available methods, from system functions to third-party apps, and also examine common errors Honor 9 owners encounter when trying to sync with Smart TV.
Preparatory stage and network requirements
Before you begin setting up the broadcast, you need to make sure your equipment is ready to use. A fundamental condition for a successful connection is the location of the smartphone. Honor 9 and TV on the same Wi-Fi network. If your router supports dual-band mode, it's highly recommended to connect both devices to the 5 GHz network, as this will provide higher throughput for transmitting high-definition video.

To activate the feature, pull down the notification shade and find the "Wireless Projection" icon. If it's not on the home screen, tap the edit button (usually a pencil or four dots) and drag the icon to the active area. Once enabled, your phone will begin searching for available devices within range.
When your TV's name appears in the list, tap it. A connection permission request may appear on the TV screen, which you'll need to confirm with your remote. After that, the image from your smartphone's screen will be copied completely to the big screen.
- 📱 Open Control Panel and select "Wireless Projection".
- 📡 Wait for the phone to detect yours Smart TV.
- 📺 Confirm the connection on the TV screen if prompted.
- 🔄 To end the broadcast, tap the icon in the notification shade again.
It's important to note that when using this method, the phone's screen may turn off to save power, but the streaming will continue. However, some copyrighted apps (such as Netflix or online movie theaters) may block the image output through Miracast, showing a black screen instead of a video. This isn't a phone error, but rather a content protection issue. DRM.
☑️ Check before connection
Broadcast via YouTube app and streaming services
If your goal is to watch videos from platforms like YouTube, Vimeo, or Twitch, using the screen mirroring feature isn't always optimal. It's much more efficient to use the built-in protocol. Google Cast (Chromecast built-in). This method allows you to play videos on your TV using your phone only as a remote control, freeing up your smartphone for other tasks and saving battery life.
The setup process is extremely simple. Make sure the YouTube app is running on your TV (or is built into your Smart TV). Open the same app on your Honor 9In the top corner of the interface, you'll see a rectangle icon with waves—this is the broadcast button.
By tapping this icon, you'll see a list of available devices. Select your TV from the list. The video will begin playing on the big screen, and a control interface will appear on your phone: you can pause, rewind, or adjust the volume without interrupting your viewing.
The advantage of this method is that it supports high resolution. 4K (if the TV supports it) and eliminates the lag typical of mirroring. Furthermore, picture quality is automatically adjusted based on internet speed, not the speed of the local Wi-Fi network.
⚠️ Note: The app interface and button layout may change after updates. If the broadcast icon isn't visible, check if it's hidden in the "More" menu (three dots).
Third-party apps for advanced features
Built-in tools are good, but sometimes they don't detect the TV or work erratically. In such cases, third-party apps from Google Play MarketThey can emulate various protocols and ensure compatibility even with older TV models.
One of the popular solutions is the application TV Cast or BubbleUPnPThese programs allow you to stream not only videos from your gallery, but also files in various formats that a standard TV player might not understand. They also often have a built-in browser for displaying web pages on the big screen.
Another option is to use receiver apps such as AirScreen, if you install them directly on an Android TV set-top box connected to your TV. This turns a regular TV into a fully-fledged AirPlay or Miracast receiver.
| Application | Connection type | Format support | Complexity |
|---|---|---|---|
| Wireless projection | Miracast / Wi-Fi Direct | Video, Photo, Screen | Low |
| YouTube App | Google Cast | Video streaming | Low |
| BubbleUPnP | DLNA | All media formats | Average |
| ApowerMirror | Wi-Fi / USB | Full duplication | High |
Using third-party software gives you more control over bitrate and resolution. For example, in BubbleUPnP You can manually adjust the quality of the streamed video if the network is overloaded. This is especially important for owners Honor 9, which store a lot of content in high resolution.
Why might the video be lagging?
Lag in wireless transmission is often caused by Wi-Fi channel congestion. If your router operates on the 2.4 GHz frequency, neighboring networks may be interfering. Switching to 5 GHz or changing the router's channel to a less congested one (1, 6, or 11) can significantly improve the situation.
Compatibility issues and their solutions
Despite the standardization of technologies, users often encounter a situation where their phone simply doesn't detect their TV. This may be due to router security settings or the operation of the TV's firewall. On some TV models, you must manually launch the "Screen Share," "MirrorShare," or "Cast" app before the phone can detect it.
Another common issue is different encryption standards. If the router is configured to only operate in encryption mode WPA3, and the TV only supports WPA2, the connection may fail. In this case, you should go to your router settings and enable mixed mode or temporarily use WPA2/WPA3 Mixed mode.
It's also worth checking your firewall settings. Sometimes antivirus software on your router or ISP's network blocks ports used for DLNA And MiracastTry temporarily disabling the firewall for diagnostic purposes.
- 🔌 Restart your router, phone, and TV one by one.
- 🔒 Check the Wi-Fi network security type (must be WPA2-PSK).
- 📡 Make sure that the "Discover new devices" feature is enabled on your TV.
- 📱 On the Honor 9, in the Wi-Fi settings, disable "Random MAC address" for the current network.
Alternative methods: USB and HDMI
If a wireless connection is not possible for some reason or the signal quality is unsatisfactory, you can always use wired methods. Honor 9 equipped with a port USB Type-C, which supports technology MHL (Mobile High-Definition Link) or DisplayPort alternative mode, which allows you to output an image through an HDMI adapter.
To do this, you'll need a special USB-C to HDMI adapter. Plug one end into your phone, and the other into your TV's HDMI port. Once connected, the TV will automatically detect the new signal source. All you need to do is select the appropriate input on your TV remote.
This method guarantees a stable image without lag or compression artifacts, which is critical for gaming or watching 4K video. However, it's worth keeping in mind that with this connection, the phone may discharge faster if the adapter doesn't have an additional power source, or, conversely, it may charge faster if the adapter supports it. Power Delivery.
⚠️ Note: Not all USB-C cables support video. Make sure your cable or adapter is marked with a lightning bolt or is labeled "Video Support" / "4K." Regular charging cables will not work.
You can also connect via the TV's USB port if it supports reading media files from external drives. In this case, you'll need to switch your phone to "File Transfer" (MTP) mode. The TV will see your phone's storage as a flash drive, and you'll be able to play videos through the TV's built-in media player, but you won't be able to control playback from your phone.
