Modern smartphones such as Honor 9A, often become the central storage for multimedia content that wants to be displayed on a large screen. Device owners often need to display photos, videos, or games on a TV, and a wireless connection is the most convenient solution. The absence of an HDMI cable eliminates the clutter of cables and allows you to control content directly from your phone screen from anywhere in the room.
Wireless data transmission technologies make it possible to implement screen broadcast There are several ways to stream files or connect to a TV. Depending on your TV model and smartphone firmware version, connection quality and stability may vary. In this article, we'll cover all current connection options, from built-in system features to specialized apps.
Before you begin setup, you need to make sure both devices—your smartphone and TV—are on the same local network. This is a fundamental requirement for most data transfer protocols, such as Miracast or DLNAIf your router broadcasts a signal at 5 GHz, make sure both devices are connected to this band to minimize latency.
Checking compatibility and preparing equipment
The first step is to analyze your TV's technical capabilities. Most modern Smart TVs support the Wireless Display System standard, but older models may require additional adapters. Honor 9A runs on a shell Magic UI (or EMUI (depending on the region), which has built-in tools for finding external displays.
You'll need a stable Wi-Fi signal. If the router is located far from the viewing area, image quality may suffer from compression artifacts or audio desync. Ideally, the distance between the access point and receivers should be no more than 10 meters, with no obstructions such as load-bearing walls.
It's also worth checking your operating system version. The developers regularly release updates that improve the module's stability. Wi-Fi DirectGo to your phone's settings and check for available software updates to rule out software errors during the connection.
⚠️ Please note: Some budget TV models may not support direct connection via Miracast without using external dongles (such as Chromecast or Miracast adapters), even if the Smart TV function is declared.
Make sure your TV is in connection standby mode. In the TV menu, this may be called "Screen Share," "Wireless Display," or "Cast." Without this mode enabled, your TV will be hidden from your smartphone.
Using the built-in Projection feature on the Honor 9A
The fastest and most native way to display an image is to use the system's "Projection" function. This method is based on the protocol Miracast, which broadcasts a 100% picture, without the lag typical of streaming video. To launch, pull down the notification shade and look for the "Projection" or "Wireless Projection" icon.
If the icon is not in the quick menu, go to Settings → Other connections → ProjectionYour smartphone will begin scanning for available devices on the network. The list may not appear immediately, so please be patient. When your TV's name appears in the list, tap it to pair it.
Once successfully connected, your phone's screen will be mirrored to your TV. You can switch between apps, play games, or present presentations. It's important to note that in this mode, your smartphone's screen will remain lit, which can drain your battery faster.
For control, the phone's touchpad is often used as a trackpad, or a Bluetooth mouse can be connected. Some TVs allow cursor control with the remote, but this depends on the specific TV model and its firmware version.
☑️ Check before connection
Streaming via Multimedia Content (DLNA)
If your goal is not screen mirroring, but viewing a specific video or photo gallery in high quality, it is better to use the protocol DLNAIn this case, the phone acts as a remote control, and the TV decodes the video stream itself, reducing the load on the smartphone and improving picture quality.
In smartphones Honor And Huawei This feature is often implemented through the Gallery app or a built-in video player. Open the video you want, tap the "Broadcast" icon (the rectangle with waves), and select your TV. The file will begin playing on the big screen, leaving you free to use your phone for other tasks.
The advantage of this method is that image quality doesn't depend on the phone's Wi-Fi module's power, as data flows directly from the router to the TV. However, supported video formats are limited by the TV's capabilities, not the smartphone's.
⚠️ Please note: The DLNA protocol does not support 5.1 surround sound through some apps, often limiting itself to stereo unless the TV decodes the original format itself.
For more advanced media library management, you can install third-party DLNA servers from the store. AppGallery or Google Play (if services are available). They allow you to create complex playlists and manage the playback queue.
Broadcasting via YouTube apps and streaming services
The most popular usage scenario is watching videos through YouTubeIt uses a proprietary transmission protocol that works even if the phone and TV are on different subnets, as long as there's internet access. To connect, open the YouTube app on your phone and tap the cast icon in the top corner.
The system will prompt you to enter a code displayed on the TV screen or will automatically find the device if the accounts are synced. This method ensures the highest picture quality, as the TV downloads video directly from the network, bypassing the phone.
Services work in a similar way Netflix, IVI, Kinopoisk and others. The main requirement is having the app on your Smart TV and logging in to the same account. This eliminates the need to keep the phone screen on.
What should I do if the broadcast icon doesn't appear?
If the icon is inactive, make sure the YouTube app is running on your TV and is on the home screen. Also, check if AP client isolation mode is enabled on your router, which prevents devices from seeing each other on the local network.
It's important to note that when streaming via YouTube, playback controls (pause, rewind) are fully synchronized. You can pause the video on your TV, and it will also stop on your phone, which is very convenient for incoming calls.
Using third-party apps for broadcasting
If built-in methods don't work or your TV doesn't support standard protocols, third-party solutions can help. Apps like Web Video Caster or TV Cast They can “trick” the system by redirecting the video stream to the TV’s address.
These programs often have built-in browsers. You open a website with a video within the app, it analyzes the stream, and offers a "Connect to TV" button. This is a universal solution for older Smart TVs or TVs with non-standard DLNA implementations.
| Application | Connection type | Advertising support | Difficulty of setup |
|---|---|---|---|
| Honor Projection | Miracast | No | Low |
| Google Home | Chromecast | No | Average |
| Web Video Caster | DLNA/Cast | Yes (in Free) | Average |
| TV Assist | Proprietary | No | High |
When using third-party software, keep in mind that free versions may contain ads or have session time limits. Paid versions typically offer codec support. HEVC And 4K.
Solution and troubleshooting
Users often encounter a situation where their phone simply "doesn't detect" the TV. In 90% of cases, the problem lies in the router settings. Check if this feature is enabled. AP Isolation (Access Point Isolation). This feature is designed for security on public networks and prevents devices from exchanging data with each other.
Another common issue is audio and video desync. This can be resolved by reducing the load on the Wi-Fi channel. Try switching your router to a less congested channel or using the 5 GHz band, which is less polluted by neighboring networks.
In some cases, rebooting the Wi-Fi module helps. Turn on airplane mode for 10 seconds, then turn it off and try searching for devices again. It's also worth clearing the cache for the Projection app in your phone's app settings.
⚠️ Note: Menu interfaces and item names may vary depending on the Magic UI version and TV model. If you don't see the options described, please consult the manufacturer's official documentation in the support section.
