With the modern multimedia capabilities of Xiaomi and Redmi smartphones, it’s easy to stream content to the big screen, turning the living room into a home theater. You can display images from your phone to your TV in several ways, without resorting to complex settings or expensive equipment. The choice of method depends on your TV model, the availability of smart features and the type of content transferred.
In this article, we will take a look at all the current connectivity methods, from built-in MIUI features to wired adapters, learn how to duplicate a screen in real time for presentations or games, and run high-quality videos from apps like YouTube or Netflix. Understanding how wireless protocols work will help you avoid delays and dissynchronization of sound.
Before you start, make sure your devices are ready to pair. The key to most wireless methods is to have your gadgets on the same LAN. If the router is running correctly, the setup process will take no more than a couple of minutes, after which you can enjoy photos and videos on a diagonal of 50 inches or more.
Device preparation and network setup
The first step to a successful broadcast is to organize the network space correctly. Make sure your Smart TV and smartphone are connected to the same Wi-Fi network. Often users are faced with the problem when the TV is running over a guest network or an Ethernet cable, and the phone is running over the mobile Internet or another router frequency range.
Check your router settings: 5GHz band is desirable for stable 4K or HDR video transmission. This standard provides higher bandwidth, which is critical for streaming without buffering. If your router is dual-band but the devices don't "see" each other, try temporarily combining networks or forcefully switching both gadgets to 2.4GHz.
⚠️ Note: If you have Guest Network on your router, devices may be isolated from each other (AP Isolation) in router settings or connect devices to the main network.
Also worth updating your TV software is that manufacturers often release patches that improve compatibility with Miracast and Google Cast protocols. Go to the TV settings menu, find the Support or About section and check for updates. On your smartphone, make sure that Bluetooth and Wi-Fi modules are enabled, even if you don't plan to use them directly for data transfer.
☑️ Checking before connection
Broadcasting through the built-in Translation function in MIUI
The easiest way to duplicate a Xiaomi smartphone screen on a TV is to use the Translation system function, which is based on the Miracast (or Wi-Fi Direct) protocol, which is supported by most modern Smart TVs. It allows you to completely clone an image from a mobile device, including desktop, menus and games.
To start the function, lower the notification curtain and find the "Translation" icon. If the icon is not available in quick access, go to Settings → Connection and Sharing → Broadcast. The system will start searching for available devices. At this point, the TV may need to confirm the connection permission, which will appear in the pop-up window.
The quality of the image depends on the power of the Wi-Fi module and the distance to the router. With this method, you can have a slight input lag, so it may not be suitable for dynamic shooters, but for viewing photos or static applications, this is a great solution. Remember, the screen of the smartphone should remain on.
💡
If the TV isn’t found, try manually running Screen Mirroring, Wireless Display, or Miracast in the app menu of the TV itself before searching from the phone.
In some cases, the system may suggest using Mi Share to transfer content if you have a Xiaomi or Mi Box TV.This protocol provides a more stable connection and lower latency compared to the standard Miracast. Make sure the TV has the latest firmware version installed to support all codecs.
Google Cast (Chromecast built-in) technology
Most modern Android TVs or Google Cast-enabled TVs allow you to stream content directly from apps. Unlike full screen broadcasts, here you only send a video stream, and the phone acts as a remote control, saving battery life and allowing you to use your smartphone in parallel.
Open an app like YouTube, Netflix or VLC Player. Find a stream icon (a rectangle with waves in the corner). Click on it and select your TV from the list. The video will play on the big screen, and the phone will have controls: pause, volume and rewind.
The advantage of this method is that video quality adapts automatically depending on the speed of the Internet. If the network is congested, the resolution will decrease, but the playback will not be interrupted. It is critical for the Google Cast method to work that the appropriate receiver is launched on the TV, which usually happens automatically when the TV is turned on.
| Characteristics | Miracast (Translation) | Google Cast |
|---|---|---|
| Type of transmission | Full screen duplication | Streaming stream from the application |
| Dependence on the phone | The screen should burn. | Other applications can be used |
| Delay. | High (not for games) | Minimum |
| Battery consumption | High-pitched | Low. |
Connection via HDMI cable and adapters
For users who want maximum image quality without compression and delays, a wired connection is ideal. Since Xiaomi smartphones do not have an integrated HDMI port, you will need a special USB-C to HDMI adapter. Importantly, not all phone models support video output via USB, since the port must support the DisplayPort Alt Mode standard.
The flagship models of the Xiaomi 13, 14, Mix and some versions of the Redmi Note series often support video output. Budget models may not transmit the image, limited to charging or data transfer. Before buying an adapter, it is recommended to check the specifications of a particular model on the official website or in a technical review.
Support check: Connect the adapter to the TV and phone. If the image doesn't show up after 5-10 seconds and the phone is just charging, the USB-C port probably doesn't support the video signal.Using a cable ensures a stable 4K picture at 60Hz, as long as it supports a TV, and is the best option for office presentations or projectors where the Wi-Fi network can be unstable or protected by corporate firewalls.
⚠️ Note: When connected via an adapter, the phone can quickly run out, as the video output consumes energy. USB on the adapter, if such a possibility is provided by the design.
Broadcasting through intermediary applications
If the built-in methods don’t work or your TV is an older generation of Smart TVs (or not at all), intermediary apps will come to the rescue, the leader in this niche is the Google Home app, which allows you to stream the screen of any Android smartphone to devices that support Chromecast.
Install the Google Home app from the Play Market. Once installed, open it and find your TV in the device list. Click on the device icon, then select Translate screen. The system will request permission to record the contents of the screen — confirm the action, and the image will appear on TV.
There are also specialized applications from TV manufacturers, such as LG TV Plus, Samsung Smart View or universal solutions like Web Video Caster, which are especially useful for streaming video files stored in the phone’s memory that are not supported by standard TV players.
Why Google Home is not working?
When using third-party applications, consider the load on the smartphone processor. Decoding video and transcoding it for transmission over the network is a resource-intensive process. If you notice a strong heating of the device or frieze, try to reduce the quality of the video broadcast in the application settings.
Resolving and eliminating delays
Even with the right setup, users can face problems: audio and video out of sync, connection breaks, or low resolution, most often due to congestion of the Wi-Fi channel, and if there are many neighbor networks running nearby, the signal can be interrupted.
Try changing your Wi-Fi channel in your router settings to a less busy one (e.g. 1, 6 or 11 for the 2.4GHz band). For the 5GHz band, select channels with 80MHz width. Also make sure there are no thick concrete walls or metal structures shielding the signal between the router and the devices.
💡
The stability of the broadcast depends on the quality of the Wi-Fi signal, and when there is interference, wired connection via HDMI is the only guaranteed solution without artifacts.
If the sound is behind the video, try settings on the TV to turn on Game mode or turn off post-processing images, which often delays. In some cases, rebooting the router and cleaning the app cache on the smartphone helps.
