Modern POCO smartphones, powered by the Android operating system, have powerful functionality that often requires displaying images on a large screen. Whether it’s watching high-resolution movies, showing presentations to colleagues or mobile gaming, screen broadcasting is becoming one of the most popular features. Xiaomi’s ecosystem offers several native tools to accomplish this task, allowing you to turn your smartphone into a universal control remote and media center.
The process of synchronizing devices may seem complicated at first glance, but the company’s engineers have provided many automated scenarios. You do not need to be an expert in networking to establish a stable connection between the POCO F5 or older model and the Smart TV. The main thing is to understand the principles of the LAN and know what tools are currently available in the firmware MIUI or HyperOS.
In this article, we will take a look at all possible methods of connection, from the standard Miracast protocol to specialized applications. We will also touch on security, connection stability and solving common errors that can occur when trying to create a wireless bridge between gadgets.
Preparing devices for synchronization
Before you start setting up software settings, you need to make sure that the physical base for the connection is prepared correctly. A fundamental requirement for most broadcast methods is to have both devices on the same LAN, which means that your POCO smartphone and TV must be connected to the same router, whether it is via Wi-Fi or an Ethernet cable (for TV).
A common mistake users make is to ignore the difference between wireless frequencies. If your router broadcasts two networks — 2.4 GHz and 5 GHz, then to ensure maximum video stream speed, you should use the 5 GHz band. However, if the TV supports only the 2.4 GHz standard, then the phone must switch to this frequency, otherwise the devices simply “will not see” each other in the list of available for connection.
⚠️ Note: Using Guest Network on a router often blocks the ability to detect devices from each other for security reasons.
It’s also worth checking the software’s relevance on both devices. Xiaomi Mi TV and Redmi TVs often come out with updates to fix DLNA and Chromecast protocol bugs. On POCO, make sure that Google Play services and system components are updated to the latest version available in your area.

For maximum stability when viewing 4K-Content is recommended to be disabled VPN on a smartphone, as it can redirect traffic through remote servers, breaking the local connection to the TV.
The method of wireless screen broadcasting (Cast)
The fastest and most common way to display images from your phone to your TV is by using the built-in “Translation” (Cast) feature, which is based on the Miracast or Google Cast protocol, which is supported by most modern Smart TVs. You do not need to install third-party apps, since all the necessary functionality is already integrated into the HyperOS shell.
To start the process, lower the notification curtain on your POCO and look for the Translation or Project icon. If it is not available in the quick access, go to Settings → Connection and Sharing → Broadcast. The system will automatically start searching for available devices on the local network. Once your TV name appears on the screen, tap it to pair.
- 📱 Open the connection settings on your smartphone POCO.
- 📡 Make sure that the Wi-Fi and Bluetooth module are enabled.
- 📺 Select your TV from the list of devices offered.
- ✅ Confirm the connection request if it appears on the TV screen.
Once the connection is successful, the image from your phone will appear on the TV, and it is important to understand that this mode is full mirroring of the screen, which means that all notifications, incoming calls and private messages will be visible to everyone in the room, so before launching the video, it is recommended to activate the Do Not Disturb mode.
☑️ Pre-broadcast checks
The quality of the transmitted image depends on the power of the Wi-Fi signal. If you notice the desynchronization of sound and video or the appearance of artifacts, try to move the router closer to the viewing area or reduce the resolution of the broadcast content in the application settings.
Using Google Chromecast technology
Many modern Xiaomi TVs have built-in support for Google Chromecast built-in. Unlike simple mirror display, this method allows you to stream content directly from the source application, which reduces the load on the smartphone processor and saves battery life.
To take advantage of this method, open the app you want to show content (like YouTube, Netflix, or Twitch). Find the stream icon, the rectangle with the waves in the corner. When you click on it, you'll see a list of available devices. Select your TV, and the video stream will start playing directly through the TV's Internet channel, not your phone.
The advantage of this approach is that you can use your smartphone for other tasks while watching, you can switch to a messenger, answer a call, or play a game, and it doesn't interrupt the movie playing on the big screen, and the picture quality is often higher, because the TV decodes the video stream itself.
| Characteristics | Broadcast (Cast Screen) | Chromecast built-in |
|---|---|---|
| Type of transmission | Full-screen mirroring | Streaming content transfer |
| Phone load | High (screen and GPU working) | Low (management only) |
| Dependence on the phone | Full (screen should be on) | Minimum (can be rolled) |
| Image quality | Depends on the power of the phone. | Maximum (decodes TV) |
It’s worth noting that Chromecast requires authorization to the same Google accounts on your TV and smartphone, although this isn’t always strictly mandatory for basic features. If the broadcast button doesn’t appear, check if the router’s firewall blocks the ports required for Google services to work.
Mi Remote app for TV management
In addition to the image transfer, Xiaomi app owners will benefit from using the smartphone as a universal remote control, and POCO preinstalled the Mi Remote app (Mi Remote), which allows you to control the TV even if it is not connected to the Internet, using an infrared port (if it is in the phone model) or a Wi-Fi network.
To set up via Wi-Fi, open the Mi Remote app and press + to add the device. Select the TV category and find your TV manufacturer (Xiaomi, Redmi, Mi). Follow the on-screen instructions to check the connection. Once successfully paired, you can switch channels, adjust volume and run apps directly from your smartphone screen.
⚠️ Note: To work with Mi Remote over Wi-Fi, the TV and phone must be on the same subnet (AP Isolation) on the router, the remote will not work.
If your POCO smartphone does not have an IR port (which is typical for many modern models), the functionality will be limited to network control, but this does not reduce usability, especially when you need to enter text for a search on YouTube or type a password from Wi-Fi, which is much faster to do with the virtual keyboard of the phone.
The Secret Feature of Mi Remote
Connection through USB-cable HDMI
For users who are critically interested in connection stability and no delays (for example, for games), wired connectivity remains the optimal solution. However, there is an important caveat: most POCO smartphones have a USB Type-C port, but not all of them support video output through this port (DisplayPort Alt Mode technology).
If your phone supports video output, you'll need a USB-C to HDMI adapter. By connecting one end of the adapter to the phone and the other to the HDMI cable that goes to the TV, you'll get the perfect image quality without compression. The system will automatically determine the external connection and prompt you to select the screen mode.
Settings → Connection and Sharing → USB- ConfigurationIn this menu, you can try to switch USB mode if the automatic determination did not work. Look for the option "Video Transfer" or "HDMI". It is worth remembering that when wired, the phone can quickly discharge, so it is recommended to use an adapter with an additional port for charging (Power Delivery).
- 🔌 Use a quality adapter USB-C to HDMI supportive 4K.
- 🔋 Connect the charger to the adapter to power the smartphone.
- 📺 Switch the signal source on the TV to the appropriate port HDMI.
- ⚙️ In the phone settings, select the resolution and refresh rate.
The wired method is also useful in situations where Wi-Fi is overloaded or unstable, ensuring that there are no friezes and connection breaks, which is especially important when demonstrating dynamic content or holding presentations.
Solving Common Connection Problems
Despite the ecosystem's fine-tuning, users can face a variety of challenges, and one of the most common problems is when the phone can't see the TV, 90 percent of the time it's solved by rebooting the router, because the network services might have been stuck, and reconnecting both devices to the network helps.
Another common problem is desynchronization of audio and video, which is often the case with high-resolution codecs on weak Wi-Fi channels, try to reduce the quality of playback in the source application or zoom in on the router. If the problem persists, check if the TV is in Eco mode or power saving, which can limit the performance of the processor.
⚠️ Warning: Antivirus apps or “cleaners” on your phone can block ports needed to detect devices on your local network.
If neither method works, try resetting your network settings on your TV. Sometimes, cached data on old connections prevents you from setting up a new session.
💡
The main key to success is the same Wi-Fi network for both devices and current firmware versions. 9 out of 10 problems are solved by restarting the router.
In some cases, manual adjustment may be required. IP-address-off IPv6 In router settings, if the protocol is not working correctly with Xiaomi devices, this is a more advanced method that requires access to the router's admin panel.
