Modern smartphones such as Huawei P40Huawei phones have powerful screens and excellent multimedia capabilities, but sometimes the display size isn't enough for comfortable viewing. Connecting the device to a large TV screen wirelessly lets you enjoy high-quality videos, photos, and games without the hassle of wires. The syncing process may seem complicated due to the lack of Google services on new Huawei models, but there are many effective ways to accomplish this.
Owners Huawei P40 often face the need to display images on a large screen, whether for a presentation, watching movies, or showing off family archives. Wireless connection via Wi-Fi is the most convenient and aesthetically pleasing solution, eliminating cable clutter. In this article, we'll examine all available methods in detail, from built-in system functions to specialized software.
Before you begin setup, make sure your TV supports Smart TV or is connected to an external set-top box. It's also crucial that both devices—the smartphone and the TV—are on the same local network. This is a basic requirement for most data transfer protocols, such as DLNA And MiracastIf the router distributes a guest network with client isolation, the connection will fail.
Preparing equipment and a Wi-Fi network
The first step is to properly configure your network environment. The stability of your video stream directly depends on the signal quality and router configuration. Huawei P40, which supports modern communication standards, the optimal use of the range will be 5 GHz, providing high throughput.
Make sure Wi-Fi is enabled on your TV and that it's logged into the same network as your phone. Some TV models require you to manually enable external connections in the network settings menu. Sometimes you'll need to allow access to unknown devices if your TV has strict security settings.
- 📶 Make sure both devices are connected to the same SSID (network name) of the router.
- 🔄 Restart your router if you experience frequent connection drops or low speed.
- 📱 On your Huawei P40 phone, enable Wi-Fi and geolocation to search for devices.
- 📺 In the TV menu, find the "Connect from a mobile device" section or something similar.
Keep in mind that building density and the number of neighboring networks can impact connection quality. If there are too many signals in the air, try changing the broadcast channel in your router settings. Huawei P40 Typically works well with networks, but interference can reduce the quality of the transmitted image.
⚠️ Important: If your router broadcasts two networks (2.4 GHz and 5 GHz) with different names, be sure to connect your phone and TV to the same frequency, ideally 5 GHz for better video quality.
Using Huawei's built-in Share and Projection feature
In the shell EMUI, installed on Huawei P40, native wireless screen projection technology has been implemented. This feature is based on the standard Miracast, which is supported by most modern TVs. It doesn't require any additional software installation, making it the fastest method.
To activate the mode, pull down the notification shade and find the "Projection" (or "Wireless Projection") icon. Once enabled, your phone will begin searching for available displays on the network. If your TV supports Wi-Fi Direct or has a built-in Miracast receiver, it will appear in the list of available devices.
Some TV models, such as Samsung or LG, may require connection confirmation on the TV screen. Once paired successfully, the image on the screen Huawei P40 Fully mirrored on your TV. This allows you to stream any apps, games, and smartphone menus.
☑️ Pre-projection check
It is important to note that when using this method, the phone may heat up, since the video stream is being actively processed. Function Huawei Share It also allows file transfer, but the projection menu is used for screen mirroring. Image quality depends on the strength of the Wi-Fi signal.
Streaming via the Huawei Video app for Smart TV
The most convenient way to view video content is to use technology DLNA or built-in smart TV features. Application Huawei Video, pre-installed on the P40, has a Cast feature that allows you to output video to compatible TVs.
Open a video or movie in your gallery or video app. In the player interface, find the streaming icon (a rectangle with Wi-Fi waves in the corner). Tap it to see a list of available devices. Select your TV from the list.
| Method | Image quality | Delay | Battery consumption |
|---|---|---|---|
| Miracast (Projection) | High (HD/Full HD) | Minimum | High |
| DLNA (Video Streaming) | Maximum (4K) | Absent | Short |
| Third-party applications | Depends on the application | Average | Average |
| Google Home (via emulator) | High | Minimum | High |
The main advantage of this method is that the phone acts only as a remote control. The video is buffered by the TV itself, so you can minimize the app or even lock the screen. Huawei P40, and playback won't be interrupted. This significantly saves battery life.
Why might the video be lagging?
If video is choppy when streaming via DLNA, the problem is most often related to your Wi-Fi router speed or distance. Try moving closer to the access point or reducing the playback quality in the app settings.
Connecting to Samsung, LG, and Sony TVs
Different TV manufacturers use their own implementations of wireless communication protocols. For Huawei P40 This isn't a problem, as the phone supports universal standards. However, for best results, it's worth considering the nuances of specific brands.
TV owners Samsung Smart View can be used, but it's difficult to install on Huawei devices without Google services. Instead, use built-in screen projection: Samsung TV automatically recognizes Miracast requests from the P40. This feature may be called "Screen Casting" in your Samsung TV's menu.
Televisions LG use technology Screen ShareWhen you enable this feature on your TV, your Huawei P40 will see it as an available device for projection. Sony Android TVs often have built-in Chromecast, which requires a separate approach described below, but they also support standard projection.
- 📺 Samsung: Look in the menu for "Screen Casting" or use the Source button.
- 📺 LG: Launch the "Screen Share" app on your remote or in the Smart TV menu.
- 📺 Sony: Make sure Screen Mirroring is enabled in your network settings.
If the automatic search doesn't yield any results, try updating your TV's software. Manufacturers regularly release patches that improve compatibility with new smartphones, such as Huawei P40Also check if your router is configured to restrict data exchange between clients (AP Isolation).
⚠️ Note: TV menu interfaces may vary depending on the model year and operating system version. For exact menu item names, please refer to the official manual for your TV model.
Using broadcast apps from AppGallery
Because Huawei P40 does not have access to the Google Play Store, the main source of applications is the store AppGallery or third-party resources like Petal Search. There are a number of effective utilities for connecting to a TV that compensate for the lack of native Google Cast services.
One of the popular solutions is the application TV Cast or its equivalents available in AppGallery. These programs scan the network, find Smart TVs, and allow you to stream videos from your browser or gallery. They often use protocols that emulate Chromecast or AirPlay.
Procedure:1. Install the translator app from AppGallery.
2. Launch the application and allow access to the local network.
3. Click the "Connect" button and select your TV.
4. Open a video or photo and click the "Cast" button.
Some apps require installation of a receiver on the TV itself if it runs Android TV or has an app store. However, most modern solutions are "install and play" and use standard network ports. Huawei P40 This is often the only way to access specific streaming features.
Solving problems with Google Chromecast on Huawei
Many users want to use the feature Chromecast built-in, which is built into many modern TVs. Huawei P40 Without Google services, this does not work correctly or does not work at all, since the Google Home system component is missing.
There is a workaround: installing a Google emulator or using web versions of services. However, the most stable solution for the P40 remains using alternative protocols, such as AirPlay (if the TV supports it) or universal DLNA clients. Some users install modified versions of Google Home, but this may be unsafe.
If your TV supports AirPlay 2 (e.g., new Samsung, Sony, or LG models), you can use Huawei's built-in "Projection" feature, which often detects AirPlay receivers. This will trick your phone into thinking it's connecting to an Apple TV and will successfully broadcast the image.
If none of these methods work, consider purchasing an external Chromecast or Miracast adapter that plugs into the HDMI port. Your phone will see it as a separate device, and the software compatibility issue will be resolved by hardware. This ensures that the "Cast" feature works in all apps.
Why doesn't the TV detect the Huawei P40 when searching?
The most common cause is that the devices are on different subnets (for example, one is connected to a guest Wi-Fi network and the other to the main network) or client isolation is enabled on the router. Also, make sure that a signal-receiving app (Screen Share, Miracast, etc.) is open on the TV, and not just the Wi-Fi connection.
Is it possible to output sound separately to speakers via Wi-Fi?
Yes, if your speakers or sound system support DLNA technology or have a companion app in the AppGallery. However, when using screen mirroring (Miracast), audio is usually transmitted along with video to the TV. Splitting the streams requires specialized apps.
Does connecting to a TV affect the internet speed on my phone?
When using DLNA (video streaming), the phone's internet speed is virtually unaffected, as the stream goes directly from the source to the TV. When using Miracast, the phone encodes the video stream in real time, which puts a strain on the processor and Wi-Fi module, which may slightly reduce the download speed of other data.
