Technology has turned a smartphone into a powerful multimedia center that manages a home theater. Users often wonder how to display images from a Xiaomi phone to a TV via WiFi to enjoy content on a large screen without unnecessary wires. This is especially true for owners of budget TV models that do not have built-in smart features, or for those who want to stream photos and videos from the gallery in high quality.
Xiaomi’s ecosystem offers several built-in tools to do this without requiring third-party apps, including Miracast, which allows you to duplicate your smartphone screen in real time with minimal latency, and DLNA technology for media and Chromecast for streaming content from apps like YouTube.
For successful connectivity, it is critical that both your Redmi or Poco smartphone and TV are on the same LAN. Data speed is directly dependent on the router’s bandwidth: a stable 5GHz signal is required to stream video to 4K. In this article, we will take a detailed look at all available methods, from regular MIUI facilities to the use of specialized applications.
Equipment preparation and network setup
Before you start setting up, make sure your hardware is ready to sync. Most modern TVs, whether Samsung, LG or Sony, have a built-in WiFi module. If you have a Smart TV model but no WiFi, an external adapter may be needed, although methods like Miracast often don't require this, as WiFi Direct technology is used.
First, check the version of the operating system on your phone. In the MIUI shell or the new HyperOS, the broadcast functions can be called differently: Translation, Wireless Monitor or Cast. Make sure both devices are WiFi enabled and connected to the same access point.
Sometimes dual-band routers can split devices into different subnets (2.4 GHz and 5 GHz), which prevents detection, in which case try temporarily switching both gadgets to 2.4 GHz for primary pairing.
💡
If the TV isn't visible on the list of available devices, try restarting the router and both plug-in gadgets, often with a DNS cache or a temporary network protocol failure.
Use of the built-in Translation function (Miracast)
The fastest way to duplicate the screen is to use the native MIUI function. This method does not require Internet, since the connection is established directly between devices using the WiFi Direct protocol. Open the curtain control panel and find the Translation icon.
If the icon isn't in the curtain, go to settings. The path usually looks like this: Settings → Connection and Sharing → Broadcast. Once turned on, the phone will start searching for available devices within range.
☑️ Pre-broadcast checks
You may see a connection request on your TV screen. Some TV models require manual activation of the signal reception mode. Look for the "Screen Share", "Miracast", "Wireless" or "Duplicate" sections of the TV menu.
⚠️ Note: When using Miracast, the smartphone battery discharges much faster, since the screen is constantly active, and the WiFi module is operating in high load mode.
The quality of the image depends on the power of the phone's processor and the speed of the WiFi module. There are small delays (lag) when controlling the interface, which is normal for a wireless connection. This is not critical for watching static photos or movies, but it can be noticeable for dynamic games.
Broadcasting via Mi Remote (for IR remotes)
Many Xiaomi and Redmi smartphones have an infrared port, which allows them to be used as a universal remote control. Although this does not transmit an image over WiFi, it helps to set up the TV to receive the signal.
Launch the app and add your TV. Choose a manufacturer from a list or use autosearch. Once set up, you can quickly switch signal sources (HDMI, AV) directly from your phone, which is convenient if the TV doesn't have Smart features.
For models without Smart TVs, you can use external consoles (TV Box), which are controlled over WiFi, in which case Mi Remote will help turn on the console or TV itself, and the image will be transmitted over the network.
What to do if the IR port is not working?
Using Chromecast Technology and Google Home
If your TV supports Chromecast built-in (often found on Android TVs and some Sony, Philips models), you can use the official Google Home app.This ensures stable high-resolution video transmission.
Install the Google Home app from the Play Market and log in to your Google account. The app will automatically find devices online. Click on the TV icon and select "Cast my screen."
| Method | Delay. | Quality. | Router dependency |
|---|---|---|---|
| Miracast | Low. | High (up to 1080p) | Minimum (WiFi Direct) |
| Chromecast | Medium | Maximum (4K HDR) | High (a stable Internet is needed) |
| DLNA | Absent. | Original file | Medium (file only) |
The advantage of the Chromecast is that the phone is just a remote control, and the data flows directly from the Internet to the TV (if you stream online content), which saves the battery of the smartphone.
Transfer of multimedia through DLNA (Local Area Network)
DLNA is ideal for viewing video files stored in your phone’s memory on a large screen, so you don’t have to duplicate the entire screen, just run the file in a supported player.
Use a standard MIUI video player or install VLC for Android. Open the video file, click on the Translation button (screen icon with a WiFi icon) and select your TV from the list.
The TV must support DLNA (often called Media Renderer) and unlike Miracast, the phone doesn’t warm as much here, as the TV box or the TV itself decodes.
💡
DLNA allows heavy 4K files to be transferred without buffering if the router supports 802.11ac but is not suitable for duplicate game or browser interfaces.
Solving and eliminating connection errors
A common problem is that the phone can't see the TV. Make sure the router doesn't have AP Isolation enabled, a security feature that prevents devices on the network from seeing each other.
If the image twitches or is interrupted, try lowering the resolution in your phone settings, and you should also move closer to the router or eliminate physical obstacles between devices.
⚠️ Warning: Antivirus apps or firewalls on your phone can block incoming connections from your TV. Try temporarily disabling protection to check.
In some cases, network resets help. Go to Settings → Connection and Sharing → Reset WiFi, mobile networks and Bluetooth. This will not delete your personal data, but will return network settings to factory settings.
