Modern Honor smartphones have powerful multimedia capabilities that allow you to stream content to large screens without using wires. Technology Wi-Fi Direct It's one of the most reliable ways to transmit images, as it creates a direct connection between devices, bypassing the router's home network. This ensures minimal latency and high image quality, which is especially important for watching 4K movies or playing mobile games on a TV.
The setup process may seem complicated at first, but if you follow the steps, it only takes a couple of minutes. You won't need additional HDMI cables or complicated adapters if your TV supports the standard. Miracast or has a built-in wireless module. In this article, we'll cover in detail how to properly initiate a device search, configure security settings, and resolve common connection issues.
It is worth noting that the shell interfaces Magic UI And EMUI The protocol may vary slightly depending on the Android operating system version. However, the basic principle of the data transfer protocol remains the same for all models, from the budget Y series to the flagship Magic line. The main thing is to ensure software compatibility and proper operation of the communication modules at both ends of the transmission channel.
How wireless broadcast technology works
Wi-Fi Direct technology is a standard that allows two devices to connect directly to each other, without the need for an access point or router. Unlike traditional Wi-Fi, where all devices communicate through a router, the Honor smartphone and TV create their own mini-network. This allows for high-speed transfer of large files and video streams without overloading the main home network.
When you launch the casting function on your smartphone, it begins scanning the airwaves for compatible receivers. Your TV, in turn, must be in standby mode or have the function activated. Screen MirroringThe protocol encrypts transmitted data, which protects your content from being intercepted by neighbors if they accidentally try to connect to your session.
⚠️ Please note: When connected via Wi-Fi Direct, your smartphone may consume more power than usual. We recommend monitoring the battery level or using a charger during extended viewing sessions.
It's important to understand the difference between simple DLNA rendering and full screen mirroring. DLNA only allows you to stream media files (photos, videos, music) that are manually selected through the app. Miracast (an implementation of Wi-Fi Direct for video) mirrors absolutely everything that happens on the smartphone screen, including menus, notifications, and games, to the TV. This makes the technology a versatile tool for presentations and demonstrations.
Equipment preparation and compatibility testing
Before you begin setup, you need to make sure your equipment is technically ready. Not all older TV models support modern wireless transmission standards, even if they have Smart TV functionality. First, check your TV's specifications to see if it supports the standard. Miracast or Wi-Fi Direct.
Honor smartphones released in the last 5-6 years have built-in support for this feature. However, on some budget models or with specific regional firmware versions, access to this feature may be restricted by software. Make sure your device is running the latest version of the operating system, as updates often contain fixes for wireless modules.
It's also worth checking the condition of the antennas. If the smartphone's case is damaged or has been repaired, the Wi-Fi signal strength may be reduced. For stable operation, the distance between the phone and TV should not exceed 5-7 meters, although under ideal conditions it can be greater. Obstacles such as concrete walls or metal structures can significantly reduce connection quality.
☑️ Check before connection
If your TV isn't smart but has an HDMI port, you can use an external adapter. There are special dongles that connect to the TV's HDMI port and receive the Wi-Fi Direct signal from your smartphone. In this case, the adapter can be powered by the TV's USB port or an external power outlet, making this method universal for any device.
Step-by-step instructions for connecting Honor to TV
The connection process can be divided into several logical steps. First, you need to activate the receiving mode on your TV. Modern remote controls often have a dedicated button labeled Input, Source or the dedicated "Broadcast" icon. Select the signal source in the TV menu. Wireless Display, Screen Share or similar.
After preparing the TV, proceed to the Honor smartphone settings. Open the notification shade by swiping down from the top and find the icon Wireless projection (Wireless Projection). If the icon is not in the quick menu, go to Settings → Other Connections → Wireless ProjectionThe system will automatically begin searching for available devices within range.
Path to settings:
Settings → Other Connections → Wireless Projection → Search for Devices
When your TV's name appears in the list on your smartphone screen, tap it. A connection confirmation prompt may appear on the TV screen. Use your remote to select "Allow" or "Accept." Once the handshake is successful, your smartphone screen will be mirrored to the TV, and you'll see the image in real time.
What to do if the TV is not found?
Make sure the TV is running a signal-receiving app (not just Wi-Fi enabled). Restart your router, even if you're not using it directly, as Wi-Fi modules can conflict when scanning channels. Try temporarily disabling mobile data on your smartphone.
Adjusting image and sound settings
After successful connection, you may encounter a situation where the image on the TV does not occupy the entire screen or has black bars on the sides. This is due to differences in aspect ratio Smartphone and TV matrices. Most modern TVs have a 16:9 aspect ratio, while Honor smartphones often use longer formats, such as 19.5:9 or 20:9.
To adjust this setting, use your TV settings. On the remote, find the button responsible for image scaling (often labeled as P.Size, Zoom or Aspect). Select "Fit to Screen," "Just Scan," or "Original" to remove edge cropping. Some Honor or Huawei TVs have automatic adjustments, but manual adjustments often produce better results.
| Parameter | Description | Recommended value |
|---|---|---|
| Permission | The number of pixels in the transmitted image | 1920x1080 or 3840x2160 |
| Frame rate | Frame rate (FPS) | 60 Hz (for games), 24/30 Hz (for movies) |
| Audio codec | Audio transmission format | AAC or SBC (automatic) |
| Latency | Control response time | Minimum Possible (Game Mode) |
When connected via Wi-Fi Direct, audio is usually automatically transmitted to the TV speakers. If you want to use an external speaker connected to the TV, make sure the correct output channel is selected in the TV's audio settings. In rare cases, you may need to switch the audio output in the "Wireless Projection" settings on your smartphone, if this option is available in your version. Magic UI.
Using the feature for games and work
Gamers often connect their Honor devices to their TVs to play on the big screen with minimal latency. Wi-Fi Direct is superior to cloud services in this regard, as the signal is transmitted directly. However, a stable connection is crucial for a comfortable gaming experience. Make sure there are no microwave ovens or other strong sources of interference in the 2.4 GHz band nearby.
For business meetings and presentations, mirroring your smartphone's screen is indispensable. You can display documents, spreadsheets, or websites directly from your phone on your TV. This mode is convenient for using your smartphone as a remote control or laser pointer. Some presentation apps have a special mode that hides messenger notifications from prying eyes.
⚠️ Important: When connecting to other people's or public displays via Wi-Fi Direct, always disable the display of sensitive notifications (bank codes, private messages) in the Honor system settings to prevent them from being displayed on the big screen.
If you plan to frequently use your smartphone to work with documents on your TV, consider connecting a Bluetooth keyboard and mouse to your phone. The on-screen keyboard on your TV can be inconvenient, but external input devices connected to your smartphone will allow you to comfortably type text that will be displayed on your TV.
Troubleshooting connection issues and errors
Despite the simplicity of the technology, users may encounter difficulties. The most common issue is that the TV simply doesn't detect the smartphone, or the connection drops after a few seconds. This is often due to a congested connection or a software glitch in the Wi-Fi module. First, try rebooting both devices: unplug the TV for 10 seconds and then reboot the smartphone.
Another common issue is audio and video desynchronization. While the video plays, the audio lags behind or precedes the image. This can be resolved by adjusting the audio settings in the TV menu (see "Audio Delay"). It's also worth checking that your smartphone isn't running any heavy downloads in the background, which could be clogging up the data connection.
- 📶 Problem: Poor picture quality, artifacts, and blocky images. Solution: Move closer to the TV, remove any obstructions, or switch your router (if using it as a bridge) to a less congested channel.
- 🔒 Problem: Password prompt when connecting. Solution: Enter the PIN displayed on the TV screen or confirm that the codes match on both devices.
- 📱 Problem: The screen goes dark on my phone, but the video continues playing on the TV. Solution: This is normal behavior to save power, but if the TV also goes dark, check the sleep timer settings in
Settings → Display & Brightness.
If all else fails, try resetting your smartphone's network settings. This will delete saved Wi-Fi passwords and Bluetooth settings, but it often resolves deep software conflicts in Android's network stack. Here's how to reset: Settings → System & updates → Reset → Reset network settings.
Alternative ways to broadcast content
If classic Wi-Fi Direct isn't working or doesn't meet your needs, there are other methods. Third-party apps like TvCast or Web Video Caster, allow you to stream content over a local network. They are often better at playing video files in certain formats that the TV's native player doesn't understand.
Another option is to use Chromecast, which is built into some apps or available through external Google dongles. The Cast protocol works differently than Miracast: the phone acts only as a remote control, while the TV downloads the stream from the internet. This reduces the load on the smartphone and saves battery life, but requires a stable internet connection on the TV.
⚠️ Note: Interfaces and menu item names may change after TV or smartphone firmware updates. If you can't find the option described, look for synonyms in the menu or refer to the manufacturer's manual for your specific TV model.
Huawei and Honor device owners also have access to the Huawei Share ecosystem feature. If you have a Huawei laptop or tablet, or a Huawei Smart Screen, content can be shared instantly by tapping the devices (NFC) or via the "Share" menu. This is the most integrated and fastest way to share content within the ecosystem.
