Modern smartphones like the Huawei P40 Lite have powerful displays, but sometimes you want to enjoy content on the big screen. Xiaomi owners often face the need to stream photos or videos to a TV. Fortunately, the Android ecosystem allows you to do this in several ways, despite the lack of Google services in new Huawei models.
There are many use cases, from showing a presentation to colleagues to watching a high-resolution movie with the whole family. Wireless is the most convenient, but wired provides maximum stability. The choice of method depends on your goals and the equipment available.
In this article, we will cover all the current synchronization methods, from built-in system functions to the use of specialized adapters, you will learn how to configure Miracast, use the DLNA protocol for media files, and connect your device via an HDMI cable.
Wireless transmission through the built-in functionality of Mi TV
The easiest way to display an image is to use the built-in wireless display feature. Xiaomi Mi TV and Android TV usually support the Miracast standard. On the Huawei P40 Lite smartphone, this feature can be called "Wireless projection" or "Translation".
To get started, make sure both devices are connected to the same Wi-Fi network. This is a critical condition, as data transfers go through a local router. If the network is congested, picture quality can suffer, so using the 5GHz band significantly reduces latency and increases flow stability.
On the Xiaomi TV remote, find the app launch button or go to the signal source menu. You need to select the option “Wireless Display” or “Miracast”, and then the TV will go to the standby mode of connection.
On the Huawei P40 Lite, lower the notification curtain down twice to open the full control panel.Look for the Wireless Projection icon. If it's not on the main panel, tap on the pencil or edit icon to add it from the list of available widgets.
Once activated, the phone will start searching for available devices. When your Xiaomi TV appears on the list, tap its name. In a few seconds, the image from the smartphone screen should appear on the TV.
- 📱 Make sure that both devices have Wi-Fi enabled.
- 📺 Select Miracast mode from Xiaomi TV source menu.
- 🔍 Activate “Wireless projection” in the Huawei curtain P40 Lite.
- 📶 For better speed, use a router with 5 GHz support.
Using the DLNA protocol for multimedia
If you don't have to duplicate the entire screen, but just show a video or a photo, it's more convenient to use DLNA technology. This method doesn't load the smartphone processor with constant encoding of the video stream, as in mirror display. Xiaomi TVs have a built-in media player that sees files on the local network.
However, Huawei’s standard file manager may not have the handy “Translate” feature, in which case it is recommended to install a third-party app, such as LocalCast or BubbleUPnP. These programs will automatically find your Xiaomi TV on the network.
Run your chosen app on the Huawei P40 Lite and open a video folder or photo gallery. In the corner of the screen there is usually a broadcast icon (a rectangle with waves).
The main advantage of DLNA is that you can control playback from your phone, but the TV will decode the video itself.This saves the battery of the Huawei P40 Lite and allows you to use the phone for other tasks while watching.
💡
If video slows down when wireless, try lowering the quality in the app settings or moving the router closer to the TV.
It’s worth noting that some video formats may not be supported by the TV’s built-in player, and in such cases, the broadcaster app may try to recode the stream on the fly, but this will require a powerful processor.
Broadcasting through YouTube and Netflix apps
The most popular scenario is video hosting. YouTube and Netflix apps on the Huawei P40 Lite (installed via AppGallery or manually) support Google Cast or similar transmission protocols.
Unlike mirroring, the phone is just a remote, and you send a command to a Xiaomi TV, and it downloads the video stream from the Internet, and it provides the best possible image quality, up to 4K, without jerking.
Open the video in the app on your smartphone. Click on the broadcast icon (a rectangle with a Wi-Fi signal) in the corner of the player. Select your Xiaomi TV. The video will run on a large screen, and you can lock the phone or use other applications.
⚠️ Note: For this function, accounts in apps on your phone and TV must be authorized, and devices must be on the same Wi-Fi network.
If the icon doesn't appear, check for app updates. In newer versions of the Huawei P40 Lite without Google services, some features may require additional customization or use of the web version via the browser.
What if YouTube doesn’t see TV?
Connecting via HDMI adapter
Wireless technology is convenient, but not always stable. If you want maximum reliability or no Wi-Fi, use a cable connection. Huawei P40 Lite has a USB Type-C port that supports video transmission, but not all cables are the same.
You'll need a USB-C to HDMI adapter. It's important to choose a model that supports the MHL standard or DisplayPort Alt Mode. Cheap charging cables may not transmit video.
Connect the adapter to the Huawei P40 Lite charging connector, and insert the HDMI cable into the Xiaomi TV. Switch the signal source on the TV to the appropriate HDMI port. The image should appear automatically.
Some adapters have an additional charging port, and it is recommended to connect the power to the adapter, since video streaming consumes a lot of power and the battery of the Huawei P40 Lite can quickly run out.
- 🔌 Use a quality adapter USB-C to HDMI video-enabled.
- 🔋 Connect the charger to the adapter to power the smartphone.
- 📺 Switch the signal source to HDMI on the Xiaomi TV menu.
- 🎮 This method is ideal for games with minimal input delay.
☑️ Checking before buying an adapter
Configure permission and frequency of update
When connecting via HDMI or wirelessly, it is important to properly configure output settings.The Huawei P40 Lite can automatically determine the capabilities of the Xiaomi TV, but sometimes manual adjustment is required.
Go to Settings → System and Updates → Projection (or similar path depending on the EMUI version). Here you can choose the display mode: Mirror (screen copy) or Advanced (if supported).
If the image is cropped at the edges or looks stretched, look for the aspect ratio settings. On a Xiaomi TV, this is often called "Screen Format" or "Just Scan." Set the value "Original" or "16:9."
For games, frame rate is important. If your TV supports 60 Hz or higher, make sure that the projection settings select this value, not 30 Hz, to keep the movements smooth.
| Parameter | Recommended value | Impact |
|---|---|---|
| Permission | 1920x1080 (Full HD) | Clearness of picture |
| Frequency | 60 Hz | Smoothness of movement |
| Format | 16:9 AM | Screen matching |
| Colour | RGB/Full | Flower saturation |
💡
The correct tuning of 1920x1080 resolution and 60Hz frequency ensures the best image quality without distortion and delay.
Troubleshooting and troubleshooting
Despite the ease of setting up, users may encounter problems, such as a Huawei P40 Lite phone that doesn’t see a Xiaomi TV, most often because of router settings or a firewall.
Check if the router is ticked with an AP Isolation check, which prevents devices from communicating on the network, blocking Miracast and DLNA.
Another common problem is desynchronizing audio and video, which is common in wireless methods, so try rebooting your router or switching to a wired connection.
⚠️ Note: If you are connected through HDMI No sound, check the audio output settings in the Huawei projection menu and select HDMI instead of a phone speaker.
Also make sure the software of both devices is updated.Older versions of Xiaomi MIUI TV firmware may have compatibility bugs with the new Huawei EMUI protocols.
