Modern Xiaomi TVs running Android TV have evolved into full-fledged multimedia centers capable of playing content from a variety of sources. However, the smartphone screen is often more convenient for quickly searching for videos, viewing a photo gallery or showing documents, and there is an urgent need to bring the image to a large display. Fortunately, Xiaomi engineers have provided many ways to implement the broadcast screen without buying expensive additional equipment.
In this article, we will take a look at all the available methods, from standard operating system functions to specialized applications from the manufacturer, learn how to use embedded protocols, configure wired connections and fix typical connection problems, which will allow you to enjoy high-resolution content directly on a Smart TV.
Most wireless methods rely on Wi-Fi Direct or DLNA technology, which allows devices to share heavy media without losing quality. You don't need to be an expert in networking to set up synchronization, because the whole process is as automated as possible. The main thing is to understand which tool is suitable for your particular situation and phone model.
Basic requirements for successful synchronization
Before you start setting up your image transfer, you need to make sure your technical infrastructure is ready to go. The fundamental condition for a wireless connection is that both devices are on the same LAN. If your phone is connected to the mobile Internet via 4G/5G and your TV is running through a Wi-Fi router, they simply won’t see each other on the list of available devices.
On older versions of Android, some features may not work at all or are unstable, and it is recommended to update the software on both TV and smartphone to the latest available version, which will support modern codecs and security protocols.
Pay attention to the bandwidth of your router. To stream video in 4K or HDR resolution, you will need a stable channel with high speed. If the network is congested with other devices, there may be delays or reduced picture quality. Ideally, use a dual-band router and connect the TV to a 5 GHz network.
⚠️ Note: When using a guest Wi-Fi network on a router, devices can be isolated from each other by security settings, making it impossible for the phone to detect the TV.
Use of the built-in Chromecast feature
The most common and convenient way is to use Google Chromecast built-in technology, which is built into almost all modern Xiaomi TVs, which allows you to stream content directly from apps such as YouTube, Netflix or Yandex.Cinema, without the need to duplicate the entire screen of the smartphone.
To get started, make sure that the Google Home app is installed on your phone, although in many cases the system will offer the necessary integration: Open a video hosting or streaming service, find a broadcast icon (a rectangle with waves in the corner), and select your TV from the list.
The advantage of this method is that the phone is just a remote control, so you can fold the app, respond to messages, or even turn off the screen of your smartphone, and the video on the TV will continue to play, saving battery life and freeing up the device for other tasks.
💡
If the broadcast icon does not appear, check if geolocation is enabled on the smartphone – in Android this is a mandatory requirement for finding devices on the local network.
The technology supports high resolution and adaptive bitrate, which means that the image quality will automatically adjust to the speed of your Internet connection, and if the channel is narrow, the system will lower the resolution to avoid buffering, ensuring smooth playback.
Full screen streaming via Mi Remote and Cast
If you want to show a video from a particular app, such as a presentation, browser or game, you will need a screen duplication feature (Screen Mirroring), which in the Xiaomi ecosystem is often the Mi Remote app or the built-in “Translation” function in the notification curtain.
The startup process is like this: lower the top curtain on your phone and find the Translation button (or "Cast," "Smart View," depending on the model). The phone will start searching for available devices. Select your Xiaomi TV in the list and the desktop image will appear on the big screen.
☑️ Check before broadcasting launch
It's worth noting that when you duplicate the screen, the load on the processor of the smartphone increases significantly. The device codes the video stream in real time and sends it over the network. So the battery can discharge faster than usual, and the phone itself can heat up. For long sessions, it is recommended to keep the smartphone on charge.
Xiaomi TV settings sometimes require you to manually allow unknown devices to connect. If the phone can't see TV, go to the settings of the TV system, look for the Network or General Settings section, and make sure that the Miracast or wireless display receive function is active.
Connecting via HDMI adapter
Wireless technology is convenient, but not always stable. If you're critically interested in transmitting images without the slightest delay, for example, for games or professional presentations, the best choice is cable. Since smartphones do not have an HDMI port, you will need a special USB-C to HDMI adapter.
It’s important to understand that not all Xiaomi phones support video output via a charging port.The DisplayPort Alt Mode feature is usually only available in the flagship Mi and Xiaomi series (digital series) models, as well as some Black Shark models. Budget Redmi and POCO often lack this capability at the hardware level.
| Type of connection | Signal quality | Delay (Latency) | Dependence on Wi-Fi |
|---|---|---|---|
| Chromecast | High (up to 4K) | Low. | Complete. |
| Mi Cast (Screen) | Medium/High | Medium | Complete. |
| HDMI Cable | Maximum. | Absent. | No. |
| DLNA (Photo/Video) | Depends on the file. | N/D | Partial |
To connect, simply insert the adapter into the USB-C connector of the phone, and connect to the adapter a standard HDMI cable that goes to the TV. The TV automatically determines a new signal source. You only need to switch the source of the signal (Source) on the TV remote to the corresponding HDMI port 1 or HDMI 2.
⚠️ Note: When buying an adapter, make sure it supports video output. Cheap charging or data cables will not be able to transmit the image, as they do not have the necessary internal contacts.
Transfer of photos and videos via DLNA
To view a personal photo gallery or archive of video stored in a phone's memory, you don't have to duplicate the entire screen. The DLNA protocol allows you to broadcast only media files using the TV's built-in player, which frees up the phone and provides better decoding quality.
Xiaomi Android TVs often have a player that supports this standard, or you can use the Gallery app. On your phone, you can open a photo or video, click the Share or Translate button and select your TV, and the file will play on the big screen.
This method is ideal for showing vacation photos to relatives or watching downloaded movies that are not supported by streaming services, while the image quality remains original, without compression, which can be used in screen mirroring.
What to do if the TV can’t see the files?
The speed of file transfer by DLNA It depends on the power of your router. 4K-files may require buffering time before playback begins.It is recommended to use 5GHz Wi-Fi for comfortable viewing of heavy content without jerking.
Third-party applications for enhanced capabilities
Staffing isn't always enough, especially if you want to stream content from apps that block screen recording, or you need specific management features. There are many utilities available in the Google Play store that solve these tasks.
One popular solution is Web Video Caster, which allows you to pull a video stream from a website and send it directly to the TV, bypassing the phone screen, saving traffic and energy, since the phone only specifies the address, and the TV downloads the video itself.
Another option is to use remote management applications such as TeamViewer or AnyDesk, although they are more focused on technical support. For gaming, there are specialized launchers that optimize the transmission of video stream to minimize input delays (input lag).
💡
Using specialized caster apps often allows you to bypass restrictions DRM-Protections that block standard screen broadcasting in paid theaters.
When installing third-party software, carefully read permissions. The application may need access to a local network and microphone (for voice search), download programs only from official sources to avoid introducing advertising software into your home network.
Frequent Problem Solving and Diagnostics
Even with the right setup, there can be failures: the TV disappears from the list, the image twitches or the sound lags behind the picture. The first thing you do is try to restart the router. Often the problem is overflowing the router's cache or conflict. IP-address.
If the sound is transmitted and the image is not, check the resolution settings on your phone. Some older TV models may not handle modern HDR or high-resolution formats correctly. Try temporarily reducing the output quality in your smartphone display settings.
In cases where nothing works, you can use USB debugging, but that requires you to turn on the developer mode, but for 95% of users, you just need to do a simple cycle: turn off the router, wait 10 seconds, turn it on, wait for the TV to load, and then try to connect from the phone.
