Xiaomi’s modern smartphones have powerful screens and processors that allow high-quality content to be broadcast. However, the diagonal of a mobile device often limits the perception of video, games or photos. Connecting to a large screen solves the problem and turns the gadget into a multimedia control center.
There are several proven synchronization methods, each with its own advantages, depending on your TV model, the availability of cables and the quality requirements of the signal being transmitted, and in this article we will look at all the current options, from wireless technologies to wired connections.
Owners of the MIUI ecosystem often look for a way to quickly display images without complex settings. Fortunately, the developers have implemented the necessary tools directly into the shell of the operating system.
Before you start setting up, make sure both devices are charged or connected to the network.Unstable power can interrupt the pairing process at the most inopportune moment, which will lead to a reset of connection settings.
Wireless connection via Wi-Fi and the broadcast function
The most popular method is the built-in Cast, which uses Miracast and DLNA technology to transmit images and sound wirelessly, and requires that the smartphone and TV be on the same local network.
Open the swipe control panel down and find the Broadcast icon. If it's not on the home screen, click the panel edit button and add this module, and the system will automatically search for available devices within range of the router.
A request for confirmation of connection may appear on the TV screen. Some Smart TV models require manual activation of the reception mode in the network settings menu, and after successful pairing, the image from the phone is fully duplicated on the large screen.
This method is ideal for viewing photos, gallery videos or presentations, but for dynamic games, there may be a slight input delay known as input lag.
The quality of the transmission depends on the speed of your Wi-Fi router, and if the network is overloaded with other devices, the image can slow down or lower the resolution.
Use of the HDMI-Type-C cables and adapters
For users who want maximum stability and no delays, wired connectivity remains the leader. You will need a special USB-C to HDMI adapter that supports video transmission.
Not all USB-C ports in Xiaomi smartphones support video output. Flagship models usually have a full-fledged interface, while budget devices can only be limited to data transfer and charging.
Connect the adapter to the smartphone, and then connect it HDMI-Switch the TV signal source to the corresponding connector. HDMI 1 HDMI 2. The image must appear automatically.
The advantage of this method is the ability to charge the phone while in use, if the adapter has an additional power port, which is critical for long-term viewing of movies in high resolution.
💡
Use adapters with an additional USB port for power, as video transmission significantly increases the battery consumption of the smartphone.
The cable connection guarantees a 4K signal transmission without compression, which is not available to most wireless protocols.
Configure via Mi Remote and IR port
Many Xiaomi smartphones have an integrated infrared port, which allows them to be used as a universal remote control.This does not duplicate the screen, but gives full control of the TV.
Launch the Mi Remote app preinstalled. Add a new device by selecting the TV category and your screen manufacturer. Follow the instructions on the screen by pressing the buttons to check the signal.
Once you've set up successfully, you can switch channels, adjust volume and change signal sources, not look for the original remote, which is especially useful if your native remote is lost or out of order.
It is important to point the top of the smartphone towards the receiver of the infrared signal on the TV. Direct visibility is mandatory, since infrared radiation does not pass through obstacles.
☑️ Checking connection readiness
The IR remote functions work even without access to the Internet, making it a reliable control tool in any conditions.
Comparison of connection methods: Characteristics table
To make it easier for you to choose the best option, we have prepared a comparison table of basic parameters, which will help you to weigh the pros and cons of each method.
| Method | Delay. | Quality. | Stability |
|---|---|---|---|
| Wi-Fi (Translation) | Medium | High. | Depends on the router. |
| HDMI Cable | Absent. | Maximum. | Very high. |
| Chromecast | Low. | High. | Tall. |
| DLNA (Media) | Low. | Original | Tall. |
As you can see from the table, wired connectivity is a win-win for all technical aspects, but wireless technology offers much more convenience in everyday use.
For games, it is preferable to use cable to avoid de-synchronization of activities, and a standard broadcast feature is sufficient to view YouTube or a photo gallery.
Broadcasting via Google Chromecast and YouTube
If your TV supports Google Cast technology or has an Android TV built in, the process is simplified to a single tap: Open the YouTube, Netflix or Google Photos app on your smartphone.
Find the broadcast icon (a rectangle with waves) in the corner of the app interface. Select your TV from the list of available devices. The video will play on the TV, and the phone can be used as a remote or for other tasks.
The main difference from a full screen broadcast is that the smartphone does not send a video stream, but only tells the TV to download content from the Internet, which saves battery power and traffic.
Why is the Chromecast device not available?
The picture quality in this mode is often higher, as the TV decodes the video itself using its power.
Problem Solving and Lack of Image
Sometimes the connection process is not smooth. If the TV can't see the smartphone, first of all check the software versions. Obsolete MIUI firmware may contain bugs in the wireless module.
Often, networked device discovery protocols (UPnP, mDNS) stop working properly after a long uptime router.
If you use third-party apps to duplicate the screen, make sure they are given all the necessary permissions in the privacy settings.Blocking access to the screen or microphone may interrupt the connection.
⚠️ Note: When using public Wi-Fi networks (cafes, hotels) the broadcast may not work due to network security restrictions that prohibit interaction between devices.
In some cases, resetting the smartphone’s network settings to factory settings helps, which will remove stored Wi-Fi passwords, but often solves problems with data protocols.
💡
90% of connection problems are solved by restarting the router and updating applications on smartphones and TV.
