Modern Huawei smartphones boast powerful multimedia capabilities, allowing you to store huge libraries of high-resolution photos and videos. However, viewing content on a small screen isn't always convenient, especially when you're at home and want to share the experience with family or simply enjoy high-quality images on a larger display. Fortunately, wireless data transfer technologies allow you to instantly stream content without the need for unnecessary wires or complicated adapters.
In this article, we'll take a detailed look at all the current methods for connecting your gadget to your TV via a local network. We'll cover both built-in system features of EMUI and HarmonyOS, as well as third-party solutions that can help if standard methods fail for some reason. You'll learn the nuances of the Miracast and DLNA protocols, and understand why streaming quality depends on the stability of your router.
Before setting up, it's important to ensure your equipment is ready for use. Outdated firmware versions or incorrect network configurations can cause delays or even a complete loss of connection. We'll walk you through the preparation steps to minimize the risk of errors and ensure smooth video playback without stuttering or compression artifacts.
Preparing equipment and a Wi-Fi network
The foundation of successful wireless broadcasting is a properly organized local network. Both devices—and your smartphone— Huawei, and the TV must be connected to the same Wi-Fi access point. If you have a dual-band router, make sure the devices operate on the same frequency band, preferably 5 GHz, as it provides the higher bandwidth required to transmit 4K video.
Make sure your TV is set to receive external connections. This feature is enabled by default on most modern Smart TV models, but in some cases, manual activation is required. Screen Mirroring or DLNA in the network settings. Without this step, the phone simply won't see the display in the list of available devices for displaying images.
⚠️ Attention: If your router is configured for AP Isolation, devices on the same network will not be able to see each other. This option must be disabled in the router's admin panel to enable broadcasting.
Signal stability is critical. If the phone is far from the router or there are thick concrete walls between it and the receiver, image quality may drop sharply. In such situations, the system will automatically reduce the stream resolution to compensate for packet loss, resulting in blurry images.
Using the built-in Screen Projection feature
The easiest and fastest way to transmit an image is to use the native shell feature, which in Huawei phones is called "Screen Projection" or "Wireless Projection." This technology is based on the protocol Miracast, which allows for real-time video transmission with minimal latency. The process is extremely simple: pull down the notification shade, find the "Screen Projection" icon, and tap it.
The system will begin searching for available displays within range. Once you see your TV's name in the list, tap it. A connection confirmation prompt may appear on the TV screen, which you'll need to accept with the remote. Your smartphone's screen will then be fully mirrored to the large monitor, including the desktop, menu, and running apps.
☑️ Check before connection
It's important to note that when using this method, your phone's screen must be on. If the device goes to sleep or you lock it, the streaming will be interrupted. This distinguishes screen mirroring mode from media library mode, where video can play in the background.
What to do if the button is not found?
If you don't see the icon in the notification shade, tap the edit icon (usually a pencil or three dots) and add the "Screen Projection" widget to the active menu. In some EMUI versions, it may be called "Cast."
Broadcast via YouTube app and streaming services
If your goal isn't mirroring your desktop, but rather watching videos from platforms like YouTube, Netflix, or online movie theaters, it's better to use the built-in Cast feature. This method is much more battery-efficient and often provides better picture quality, as the TV downloads the stream directly from the internet, and the phone acts only as a remote control.
To get started, open an app like YouTube on your Huawei device. Find the casting icon—the rectangle with Wi-Fi waves in the corner—and tap it. Select your TV from the list. The video will start playing on the big screen, and you can control the volume, skip videos, or even exit the app without pausing playback.
- 📺 Advantage: The phone does not heat up or drain its battery because it does not decode the video stream.
- 🌐 Independence: You can use your smartphone for other tasks while watching a movie.
- 🎬 Quality: The maximum bitrates available for your subscription and internet speed are supported.
It's important to note that app accounts may require authorization for this feature to work. Also, make sure the latest version of the YouTube app or corresponding service is installed on your TV, otherwise the data exchange protocol may not work correctly.
⚠️ Attention: The Cast feature only works within specific apps. If you try to cast a video from your gallery or browser using this button, it may be grayed out, and you'll have to use the screen mirroring method.
Transfer files via DLNA and media servers
For viewing video files stored in the phone's memory (downloaded movies, home recordings), the technology is ideal DLNAUnlike Miracast, it doesn't mirror the screen, but sends the media file itself to the TV for decoding. For this, you can use the built-in "Video" player on Huawei or third-party apps like BubbleUPnP or VLC.
In the standard Video app, open the desired file and tap the (TV) icon in the corner of the interface. Your phone will find a compatible TV on the network. Once connected, the file will begin playing on the TV. This method is advantageous because it supports subtitles and allows you to control rewinding without the lag typical of screen mirroring.
If your TV doesn't recognize the default player, try installing VLC for Android. In this app, open the menu, select "Rendering" (or "Cast"), and select your device. VLC has powerful built-in codecs and can handle virtually any video file format that your TV's native player can't handle.
| Characteristic | Miracast (Projection) | DLNA (Media Server) | Google Cast (YouTube) |
|---|---|---|---|
| Transmission type | Real-time screen stream | File transfer | Link to the stream |
| Phone addiction | High (screen on) | Average (control) | Low (remote control only) |
| Image quality | Depends on Wi-Fi signal | Original file | Maximum network |
| Subtitle support | As part of the picture | Separate stream (often) | Depends on the service |
Troubleshooting connection and latency issues
Despite technological advances, wireless connections sometimes experience issues. The most common problem is audio and video desynchronization or intermittent image flickering. This almost always indicates insufficient channel bandwidth or interference from neighboring Wi-Fi networks.
Try rebooting your router and both devices. Often, simply resetting the network module cache can help restore a stable connection. Also, check that your phone isn't running any background downloads of large files that could be choking the video stream. For viewing high-definition video, a network speed of at least 20-30 Mbps.
If your TV is old and doesn't support modern standards, and you don't want to buy a new one, you can purchase an external MiraScreen adapter or a similar dongle. It plugs into the HDMI port and creates an access point to which your phone connects directly, bypassing the main router, often solving compatibility issues.
In some cases, the problem lies with Huawei's power saving settings. Aggressive optimization algorithms can "kill" the streaming process to save battery. Go to battery settings, find the app you're streaming through, and set it to "Run in background" or disable power saving for it.
Alternative apps and third-party solutions
When standard tools fail, specialized apps from the AppGallery or Google Play Store come to the rescue. One of the most popular solutions is TV Assist or LocalCastThey can detect virtually any DLNA-compatible device and have flexible codec settings.
For Huawei ecosystem users, the app is especially interesting Huawei Share (or OneHop), if your TV also supports this technology (usually Honor or Huawei Vision models). Simply touch the back of your phone to the NFC area on the remote or TV, and the connection will be established automatically, eliminating the need for passwords or complicated settings.
- 📱 Web Video Caster: Ideal for streaming video from browsers that don't have a Cast button.
- 🔄 AllConnect: Turns your phone into a universal media server with AirPlay and DLNA support.
- 🖥️ TeamViewer Host: Allows you to control your TV (if it's Android TV) or stream your screen with additional control features.
Using third-party software gives you more control over the process. For example, you can change the aspect ratio, overlay subtitles from external files, or stream audio separately to a Bluetooth speaker if your TV doesn't produce the required sound quality.
Why doesn't my phone see my TV in the list of devices?
Most often, the problem is that the devices are on different subnets (for example, one on a guest network, the other on the main network) or access point isolation is enabled. Also, check whether your antivirus or firewall software is blocking local connections on your phone.
Is it possible to stream 4K video over Wi-Fi?
Yes, it's possible, but it requires ideal conditions: a Wi-Fi 5 (ac) or Wi-Fi 6 (ax) router operating in the 5 GHz band and a 4K-capable TV. The 2.4 GHz band (throughput) is usually insufficient for stable 4K.
Does broadcasting affect internet speed?
When using Cast mode (YouTube), traffic goes directly from the server to the TV, without loading the phone's bandwidth. When using screen mirroring (Miracast), the phone's internet connection may be slower because the Wi-Fi module is busy transmitting the video stream to the TV.
