Modern smartphones Huawei Televisions offer powerful multimedia capabilities that are often lost on a small screen. Viewing photos, YouTube videos, or presentations is much more comfortable on a larger TV. Fortunately, wireless technology eliminates unnecessary wires and cables while ensuring stable signal transmission.
There are several proven methods for streaming images, each with its own characteristics and hardware requirements. The method you choose depends on your TV model and operating system version. Android or HarmonyOS, as well as what exactly you plan to stream. In this article, we'll take a detailed look at all the current connection options.
You don't need complex technical knowledge or specialized third-party software to get started. Most of the necessary functions are already built into the shell. EMUI or Magic UIThe main thing is to make sure that both devices are on the same local network and ready to exchange data.
Wireless image transmission technologies
Before you begin setting things up, it's important to understand what protocols are used for communication. Miracast — is a wireless media streaming standard that allows you to mirror your smartphone's screen to your TV in real time. This technology doesn't require an internet connection, as it creates a direct connection between devices via WiFi Direct.
The second popular standard is DLNAIt works differently: the phone acts as a server, and the TV plays content (videos, photos, music) from the smartphone's memory. Unlike Miracast, it doesn't mirror the screen; only a specific media file is streamed. This saves battery life and reduces processor load.
Huawei has also developed its own ecosystem Huawei Share, which combines the benefits of both protocols. It provides a faster connection and better stability, especially if the TV also supports Huawei technologies or has a built-in NFC module.
What is the difference between casting and screen dubbing?
Casting (DLNA) transfers only the media file, allowing you to control your phone independently. Mirroring (Miracast) copies the entire smartphone screen, including notifications and the home screen.
Preparing equipment and network
A successful connection directly depends on properly configured network settings. Both devices—the smartphone and the Smart TV—must be connected to the same WiFi access point. If you have a dual-band router, make sure both devices operate on the same frequency (2.4 GHz or 5 GHz), although modern routers often combine them into a single network.
Check your software is up to date. Your TV may require a firmware update for Miracast protocols to work properly. On your Huawei smartphone, you should also check for updates in the [Unknown] section. Settings → System and updates.
⚠️ Warning: Antivirus software or firewall settings on your router may be blocking the search for devices on your local network. If the search doesn't produce any results, try temporarily disabling AP Isolation in your router settings.
The distance between devices should also be considered. For stable high-resolution video transmission (4K or Full HD), the distance should not exceed 5-7 meters, especially if the room contains many concrete walls or other sources of radio interference.
Wireless Projector Method (Screen Mirroring)
The most universal way to project an image is to use the built-in "Wireless Projector" feature. This method works on most Miracast-enabled TVs, regardless of brand. First, activate the signal reception feature on your TV. In your Smart TV menu, this may be called "Screen Mirroring," "Cast," "Miracast," or "Screen Mirroring."
On your Huawei smartphone, pull down the notification shade and find the "Wireless Projector" icon. If it's not on the first page, tap the edit icon (usually a pencil or four dots) and add the widget to the quick access panel. Tap it, and your phone will begin searching for available devices.
When your TV appears in the list, tap its name. A connection confirmation prompt may appear on the TV screen. Accept it using the remote. After that, the image from your phone will be fully displayed on the big screen.
☑️ Check before connection
Broadcasting via the Huawei Share app
Huawei smartphone owners can use a more advanced method via the "More" menu in Settings. Open Settings → More connections → Huawei ShareHere you can activate not only file transfer, but also the "Stream to PC/TV" function.
This method is often more stable than standard Miracast, as it uses optimized Huawei codecs. It also allows you to stream audio separately or along with video, which isn't always possible with standard mirroring. If your TV supports the DLNA protocol, it may be detected as a media device in this menu.
For users with Huawei or Honor laptops, there's a "Multi-Screen Collaboration" feature, but it's not designed for TVs. However, if you have a Huawei TV box, this will be your primary and fastest method.
Using the YouTube app and streaming services
If you're watching videos from YouTube, Netflix, or other streaming platforms, screen mirroring isn't necessary. These apps use their own casting technology (Google Cast), which often provides better picture quality.
Open the YouTube app on your phone and find the video. In the upper right corner of the player, tap the rectangle icon with waves (broadcast). Select your TV from the list. The video will start playing on your TV directly over the internet, and you can use your phone as a remote or set it aside.
The advantage of this method is that the phone doesn't drain battery power decoding the video and streaming it. The TV downloads the content itself, ensuring the highest quality possible for your internet speed.
| Method | Quality | Battery consumption | Best for |
|---|---|---|---|
| Miracast (Projector) | Depends on the signal | High | Games, photos, browser |
| DLNA / Huawei Share | High | Average | Local video files |
| YouTube Cast | Maximum | Short | Online video |
| HDMI cable | Ideal | Charging is in progress | Presentations, 4K content |
Solution and sound settings
Users often encounter a situation where the image is present, but the sound continues to come only through the phone's speaker. In this case, check the audio settings in the "Wireless Projector" menu or in the Bluetooth settings, as sometimes the audio channel can switch independently.
If your connection is constantly dropping or the image is choppy, try lowering the streaming resolution. On some Huawei models, this can be done in the engineering menu or by simply disabling background downloads on your phone. You should also reboot your router, as network buffer overflow is a common cause of problems.
⚠️ Note: When connecting via Miracast, some DRM-protected apps (such as online movie theaters) may display a black screen instead of video due to copy protection. In this case, only the built-in Smart TV app or an HDMI cable will help.
Keep in mind that it's best to keep your phone's screen on while actively streaming, as some models may interrupt data transfer to save power. It's also a good idea to disable Do Not Disturb mode to prevent notifications from obscuring content on the big screen.
Alternative connection options
If wireless methods don't work or you're not satisfied with the quality, there's always the option of a physical connection. For modern Huawei devices with a port USB Type-C You can use an HDMI adapter. This ensures lag-free signal transmission at maximum resolution.
You can also use external devices such as Google Chromecast, Apple TV, or Android set-top boxes. They connect to the TV's HDMI port and receive the signal from your phone through their apps, often offering more stability than the TV's built-in Smart features.
In conclusion, the choice of method depends on your needs. Miracast is suitable for quickly sharing photos, YouTube Cast is suitable for watching movies, and a wired connection is best for lag-free gaming.
Why can't the TV detect my Huawei phone?
Most often, the problem lies in the devices being connected to different networks (for example, one to a guest network and one to the main network) or access point isolation being enabled on the router. Also, check if the TV is hidden in the privacy settings.
Is it possible to display a screen on an old TV without Smart TV?
Yes, you'll need to purchase an external adapter (such as an AnyCast or Miracast dongle) that plugs into your TV's HDMI port. This will create a signal receiving point that your Huawei will see.
The video is lagging while streaming, what should I do?
Try moving your phone closer to the router, closing background apps on your smartphone, or lowering the video quality in the app itself. Restarting the WiFi module on both devices may also help.
Does the projector transmit sound wirelessly?
Yes, Miracast transmits both video and audio. However, if you don't hear any sound, check the media settings in the connection menu or change the audio output in the Bluetooth settings.
