Modern smart home ecosystems make it easy to combine devices from different brands to create a single multimedia environment. Connecting a Xiaomi smartphone to a Sony Bravia TV gives you access to a huge array of content on a large screen without unnecessary wires. Owners of technology often face the need to bring photos, videos or games from a mobile gadget to a diagonal of 50 inches or more.
The process of synchronizing devices is based on the use of Wi-Fi Direct and Miracast protocols, which are built into the Android and Android TV operating systems. Although the interfaces of the MIUI and Google TV shells may differ, the basic principles of signal transmission remain unchanged. You do not need to buy expensive adapters or cables if both devices are in good condition.
In this article, we will take a look at all the available broadcasting methods, from standard system functions to specialized applications. We will look at the nuances of network configuration, possible connection errors and how to fix them. Proper configuration will ensure a stable picture without delay and desynchronization of sound.
Preparation of equipment and network
The first and most critical step is to provide a single network environment for both devices. Wireless connection requires that Xiaomi smartphone and Sony Bravia TV be connected to the same Wi-Fi hotspot. If your router supports dual-band operation (2.4 GHz and 5 GHz), it is advisable to use 5 GHz frequency to transmit high-resolution video streaming.
Make sure that the external device detection feature is activated on the TV. On Sony menus, this is often called Screen Mirroring or Miracast. On Xiaomi smartphones, this technology is also built into the system, but can be called Translation or Wireless Monitor. Without activating these services, device search will not be possible.
⚠️ Note: If your router has a client isolation function (AP Isolation, devices won't see each other on the same network, so you need to go to your router's settings and turn off this option for your local network. LAN.
Check the software on both gadgets. Older versions of firmware may contain bugs that prevent stable DLNA or Cast connection. System updates often solve problems with codec and network standards compatibility.
☑️ Preparation for connection
Use of the built-in Translation function in MIUI
The MIUI shell and its successor HyperOS have a native screen duplication tool that doesn’t require third-party software. Open the curtain control center to start and find the Translation (or Cast) icon. If there’s no icon, add it via the Quick Button Editing menu in the upper right corner of the curtain.
Once the function is activated, the phone will start scanning the available signal receivers. Your Sony Bravia TV should appear on the list. Click on the model name, and a request for confirmation of connection may appear on the TV screen. Use the remote control to agree.
This technique uses Miracast technology, which transmits real-time images with minimal latency, which is ideal for displaying presentations, photos or web surfing, but for high-dynamic games, the delay of 100-200 ms can be palpable.
💡
If the search doesn’t find the TV, try rebooting the Wi-Fi module on your phone by turning on and off Flight Mode.
In some regions or firmware versions, the feature may be called a Wireless Monitor, and the way it works is the same: the device creates a direct connection or uses a local network to transmit a video stream, and the quality of the image depends on the power of the Wi-Fi signal and the load of the channel.
Broadcasting through the Google Home app
Because Sony Bravia TVs are powered by Android TV, they have built-in support for Google Cast, which is the most stable and functional way to transfer content, and you’ll need the official Google Home app available from the Play Market Store to implement it.
Install the app on your Xiaomi smartphone and log in to your Google account. The program will automatically detect the TV if it is connected to the same Wi-Fi network. In the application interface, select your TV icon and click the Translate screen button. The system will warn you about the possible impact on battery consumption.
| Parameter | Miracast (Translation) | Google Cast | HDMI-cable |
|---|---|---|---|
| Type of connection | Wireless (P2P/Wi-Fi) | Wireless (Wi-Fi) | Wired |
| Delay (Latency) | Medium (100-300 ms) | Low (depends on router) | Absent. |
| Image quality | Depends on the signal. | Adaptive (up to 4K) | Maximum. |
| Battery consumption | High-pitched | Medium. | Low (charging) |
The advantage of the method through Google Home is the ability to broadcast not only the entire screen, but also specific tabs from the Chrome browser or media files. In addition, the phone can act as a remote control, which is convenient for navigating the Smart TV menu.
⚠️ Note: When streaming through Google Home, make sure that the TV has updated Google Play services. The outdated version may cause audio and video to be out of sync.
Using Chromecast in Applications
Special attention should be paid to the built-in Chromecast feature in popular applications such as YouTube, Netflix or VK Video, in which case the phone does not broadcast its entire screen, but acts only as a remote, instructing the TV to download the video stream from the Internet.
This drastically reduces the load on the Xiaomi smartphone processor and saves battery life. Image quality will be maximum, since Sony TV decodes video on its own using its powerful processor and buffering.
To use it, find the characteristic rectangle icon on your phone, with the waves in the corner. Click on it and select your Sony Bravia. The video will run on your TV, and the playback, volume and subtitles buttons will appear on your smartphone screen.
💡
Using the built-in Chromecast in applications gives the best picture quality and does not load the smartphone battery, unlike full screen duplication.
Importantly, to work with this feature, both devices must be logged in to the same Google account or be on the same subnet if the accounts are different. 4K permit.
Connecting via USB and alternative methods
If the wireless connection is unstable or impossible, you can use a wired connection. For Xiaomi smartphones with a USB Type-C port that supports the DisplayPort Alt Mode standard, you can output images via a Type-C to HDMI cable. However, most budget and mid-range Xiaomi models do not support video transmission over USB.
Owners of such devices will have to purchase a special adapter hub with support for MHL or Slimport, if the phone model allows it, otherwise the only wired option is to use adapters with support for DisplayLink technology, which require installing a separate driver on the phone.
An alternative wireless method is to use the DLNA protocol. By installing a DLNA-enabled file manager (such as Mi Explorer or VLC) on your phone, you can share a video file and open it on your TV. The TV will see the phone as a media server and play the file.
⚠️ Note: When using cheap HDMI-If you have an adapter without external power, the image may disappear or flicker.
There is also the option of using third-party repetitive apps, such as Web Video Cast. They allow you to stream videos from browsers that do not have built-in Cast support by redirecting the stream to Sony's built-in TV player.
Solving and eliminating errors
The most common problem is when devices simply "can't see" each other. 90% In some cases, this is solved by checking the Wi-Fi range, make sure that the phone and TV are connected to the same network (for example, not to the same network). Home_2.4 and Home_5G If the router does not connect them to a logical network).
If you have a connection but the image is slowing down or low resolution, try to reduce the load on the channel. Turn off downloads on other devices, get closer to the router or switch to 5 GHz. Also helps cleaning the cache of the Google Play Services service on the TV.
Secret codes and network reset
If you desynchronize your audio and video while watching movies through Miracast, try changing the audio output settings in the phone’s engineering menu (code ##6484## to enter test mode, if available) or simply use Google Cast, which buffers data better.
