Modern Xiaomi Redmi smartphones have powerful screens, but their capabilities are often not enough to view content on a large screen. Users often wonder how to display an image on a large display to enjoy movies or games in high resolution. There are several proven methods to accomplish this task, from wireless technology to wired connections.
The choice of the particular method depends on the model of your TV and the presence of certain features in the MIUI firmware. Some methods require a stable network, others work independently. In this article, we will discuss all the options available in detail so that you can choose the most suitable for your situation.
Before you start setting up, make sure that both devices are charged or connected to a power source. Battery instability can interrupt the connection process at the most inopportune time, which is especially critical when transferring large amounts of data.
Wireless connection through the built-in function "Translation"
The easiest and most popular way to do this is to use a tool built into the MIUI shell called Translation, which is based on the Miracast protocol, which is supported by most modern Smart TVs. You don't have to install third-party apps to get started, you just have to activate the module you want on the system.
It is important that the smartphone and TV are on the same local Wi-Fi network. If the router distributes at 5 GHz, the transfer speed will be higher and the delay is minimal. Old routers, operating only at 2.4 GHz, there are small slowdowns when playing video in 4K.
To start the process, open the notification curtain and find the Translation icon. If it's not on the home screen, click on a pencil or edit button to add a widget to the active area. Once turned on, you'll start looking for available devices within network range.
- 📱 Open the control menu and select “Translation».
- 📡 Make sure the TV is on and connected to the same Wi-Fi network.
- 📺 Select the name of your TV from the list that appears.
- 🔗 Confirm the connection on the TV screen if a request appears.
Once successfully paired, the smartphone screen is fully duplicated on the TV. You can switch between apps, watch videos from the gallery or play games. Note that in horizontal mode, the image will occupy the entire screen, which provides a cinematic experience.
Use of Google Cast (Chromecast) technology
If your TV doesn’t support Miracast natively but has a built-in Chromecast or runs on Android TV, you can use the Google ecosystem. Xiaomi Redmi phones have built-in support for this technology at the system level, making the integration process as smooth as possible.
The method requires Google Play Services to be installed on your smartphone. Unlike a simple screen broadcast, here you can stream content from specific apps like YouTube or Netflix without using the battery to render the image in real time.
⚠️ Note: When using Google Cast, content management is done via phone, but buffering occurs on the TV side, which reduces the load on the smartphone battery.
To start broadcasting, open an app like YouTube and click on the box icon with the waves in the corner. The system will suggest a list of available devices. Select your TV and the video will start playing on the big screen while the phone can be used for other tasks.
This method is especially convenient for streaming services, as it allows you to maintain high quality images even with a weak Wi-Fi signal. However, for broadcasting desktop or games, it is not suitable, as it is primarily intended for media content.
What if the TV is not visible on the list?
Connection via HDMI cable and Type-C adapter
For users who want maximum stability and no delays, a wired connection is ideal. However, there is an important caveat: not all Xiaomi Redmi models support video output via a USB Type-C port. This feature is called MHL or DisplayPort Alt Mode.
Flagship models often have this support, while budget Redmis can only transfer data and charge.Before buying an adapter, it is recommended to check the specification of your processor and port on the manufacturer's official website.If support is available, you will need a Type-C adapter on HDMI.
The connection is "insert and work"; the TV recognizes the phone as an external signal source, similar to the connection of a laptop; in the settings of the phone, a screen resolution menu may appear, where you can choose between 1920×1080 or 3840×2160.
| Type of connection | Image quality | Delay (Latency) | Dependence on Wi-Fi |
|---|---|---|---|
| Wi-Fi (Translation) | High (compression) | Medium (50-200 ms) | Complete. |
| Google Cast | Maximum. | Low (depending on the server) | Complete. |
| HDMI Cable | No loss. | Minimum (<10 ms) | It doesn't matter. |
Using the cable also allows you to charge the device at the same time if the adapter has an additional power port, which is critical for long gaming sessions or watching marathons of series, when the battery is discharged faster than usual due to the high brightness of the screen.
☑️ Checking before buying an adapter
Broadcasting via Mi Remote and IR port
Many Xiaomi smartphones feature an integrated infrared port, which turns them into universal remote controls. Although this does not transmit the image to the screen, the Mi Remote app allows you to control the TV, which is often a companion task when connecting multimedia.
With this app, you can switch your TV sources, adjust the volume and change the channels, which is convenient if the original remote is lost or the batteries are dead, and the app's database covers thousands of models from various brands.
To set up, open the Mi Remote app, click Add Device, and select TV category. The phone will offer several code options that you need to check by pressing buttons on the screen. After successful testing, the remote is ready to go.
It's worth noting that the IR port is line-of-sight, so there should be no major obstacles between the phone and the TV receiver, and this is not a restriction on Bluetooth remotes, but the IR signal requires a straight line.
Solving Connection and Buffering Problems
Even with the right setup, there can be technical difficulties, often the problem is overloaded wireless channel or outdated software, if the image twitches or the sound lags behind the video, you need to conduct a network diagnostic.
Try restarting the router by disconnecting it from power on 10-15 This will clear the cache of the device and select the least loaded channel. Also check for updates for the YouTube app or the Android System WebView component.
⚠️ Warning: Antivirus apps or firewalls on your phone may block your local connection. Try temporarily disabling protection to test your hypothesis.
If the problem persists in only one app, try clearing its cache through the Android Settings menu. Go to Settings → Apps → All apps, find the problem software, and select Clear Cache. This won't delete your personal data, but will fix possible errors in temporary files.
💡
For high graphics games, use the Do Not Disturb mode so that incoming calls do not overlap the image on the TV and do not interrupt the broadcast process.
Alternative applications for advanced users
If standard methods don’t work or require advanced functionality, you can turn to third-party solutions from the Google Play store. Apps like Cast to TV or AllConnect offer more flexible settings for codecs and file formats.
Some programs allow you to broadcast not only the screen, but also specific video files that the native TV player does not read, in which case the phone acts as a server, decoding the stream on the fly and sending it to the TV.
When using such gates, it is important to monitor the temperature of the smartphone. Decoding video in high resolution puts a serious strain on the processor. It is recommended to remove the case for better heat removal during long sessions.
💡
The most stable connection for games is provided by an HDMI cable, and for watching videos from the Internet, the best choice is Google Cast or embedded broadcast.
