How to sync your TV with Xiaomi Redmi phone

Xiaomi Redmi smartphones are powerful multimedia centers, often limited by screen size. It’s much more convenient to use a large TV display to watch movies, photos or presentations. Fortunately, Xiaomi’s ecosystem offers many built-in tools for fast and high-quality image transfer without having to buy expensive adapters.

The synchronization process depends on your TV model and the version of the MIUI or HyperOS operating system installed on your smartphone. Most modern TVs support Miracast or DLNA protocols, which allows you to stream content directly over a Wi-Fi network. In this article, we will detail all the current ways of connecting, from standard system functions to specialized applications.

Before you start setting up, make sure that both your phone and your TV are connected to the same wireless network, a critical condition that causes 90% of device search errors to be ignored. If a router distributes 2.4 GHz and 5 GHz, it is desirable that the devices be connected to the same frequency, although modern routers often combine them into a single network.

Use of the built-in Translation function in MIUI

The easiest and fastest way to bring an image from Redmi to a large display is to use a standard system widget. In the MIUI shell, this feature is called “Translation” (Cast) and is based on Miracast technology, which allows you to completely duplicate the screen of your smartphone, including the desktop, menus and running applications.

To start the function, you need to unlock the phone and lower the notification curtain down. Among the standard icons, find the Translation button. If it is not in the visible part, click on the edit button (usually a pencil icon or three dots) and drag the icon to the active area.

⚠️ Note: If the TV doesn’t appear in the list, check your Smart settings. TV. Some models of Samsung or LG You must manually allow the connection via the “Connect to mobile device” or “Screen Mirroring” menu».

Once you select your TV, you may have a request for permission to connect on your TV screen. Confirm the remote. Now the smartphone screen is fully synchronized with the TV. To stop the broadcast, you just need to click on the Translation icon again and select Turn off.

The quality of the transmission depends on the speed of the Wi-Fi router, and when watching high-resolution video, there can be small delays, since the signal is transmitted in real time, and for viewing static photos or presentations, this method is ideal.

Connecting with Google Home and Chromecast

Many modern TVs have built-in support for Chromecast built-in technology, which allows you to stream content from apps (YouTube, Netflix, Chrome browser) or the entire screen of the phone with higher stability than through the standard Translation.

If the app is not installed, you need to download it from the Google Play Store. Once installed, open the program and make sure you use the same Google account as you use on your TV (if authorization is required).

• 📺 Click on your TV icon in the list of devices.
• 🖥️ Select the option “Cast my screen).
• ✅ Confirm the start of the broadcast in the pop-up window.

The advantage of the method through Google Home is stream optimization: When you run a YouTube video on your phone and select the broadcast icon, the phone sends only a link to the video stream to the TV, not the image itself, which reduces the load on the smartphone processor and battery.

💡

To minimize delays when playing games through screen broadcast, use a router that supports Wi-Fi 5 (AC) or Wi-Fi 6 (AX) standards.

It is worth noting that some applications may block the broadcast of the screen due to copyright (DRM-In such cases, instead of the image, you'll see a black screen, although the sound will be transmitted.

Transfer photos and videos via Mi Share and DLNA

If your goal is not to duplicate the screen, but to view a personal library (recreation photos or videos shot on a Redmi camera), it is more convenient to use the DLNA protocol. In the Xiaomi ecosystem, Mi Share or the built-in Mi Video player is responsible for this.

The DLNA protocol allows you to transfer files to your TV, where they are played in-house by Smart TV. This frees your smartphone from constantly working the screen and decoding video. On Android TVs, it is often enough to simply open the Media Player app or the like.

Let’s look at the algorithm of actions through a standard video player:

1. Open the application "Mi Video" or "Gallery".


2. Select the desired file to play.




3. Click on the icon "Translation" (rectangle with waves).




4. Select your TV from the list.

Unlike a full screen broadcast, you can roll up the app or even lock your phone, and the video on the TV will keep going, which is especially useful if you need to answer a call or check your messages without interrupting your viewing.

Mi Share also allows files to be transferred directly between Xiaomi devices and Mi TV Stick or Android TVs without using a router, creating a direct access point, but this mode requires pre-configuring in the Data Sharing menu.

Use of USB-C cable to HDMI

Wireless technology is convenient, but it doesn’t always provide the quality or stability needed, especially in areas with poor signaling. In such cases, wired connectivity comes to the rescue. However, there is an important caveat: not all Xiaomi Redmi smartphones support image output via the charging port.

The technology is called MHL (Mobile High-Definition Link or DisplayPort Alt Mode.Most of the budget and mid-budget Redmi models (Note series, the usual series without the console) Pro/Ultra) Support is usually given to flagship models (Xiaomi series). 12/13/14, Some Redmi K-series).

To connect, you will need a special USB-C adapter (hub) on HDMI.

• 🔌 Connect the adapter to the smartphone charging connector.
• 📺 Put the cable in. HDMI adapter.
• 📺 Switch the signal source to the appropriate port (HDMI 1, HDMI 2).

If your phone supports video output, the image will appear automatically. If the screen is black, then the USB-C port in your Redmi model only works in USB 2.0 mode for data transfer and charging, and the wired method will not work.

💡

You can check the support of the video output in the model specifications on the official website: look for the presence of DisplayPort or MHL in the description of the USB interface.

With wired connections, there are virtually no delays, making this ideal for gaming or watching 4K content at high bitrate, and the phone in this mode can continue to charge if the hub has an additional power port.

Remote management via Mi Remote

While this feature doesn’t broadcast an image, it’s an important part of syncing your smartphone with your TV within the smart home ecosystem.Mi Remote (Mi Remote) turns your phone into a universal remote control, which is especially true if your native remote is lost or depleted.

There are two ways to run the app: through an IR port (if you have one in your Redmi model) and through Wi-Fi. The IR port allows you to control even "stupid" TVs that are not connected to the Internet. Wi-Fi management works only with Smart TVs.

To configure via Wi-Fi:

1. Open the Mi Remote app on your smartphone.
2. Click "Add device" and select "TV".
3. Select the TV brand from the list.
4. Follow the instructions on the screen for pairing.

Once paired successfully, you can control volume, switch channels and run applications directly from the Redmi screen, creating the feeling of a single device, where the phone becomes the central hub for media management.

Comparison of Connection Methods and Problem Solving

The best way to synchronize depends on your specific tasks: whether you need to play games, just show a photo or watch a movie in high quality.

A common problem is desynchronizing sound and image. If you encounter this, try lowering the quality of the video on the streaming service or rebooting the router. Also make sure that the TV turns off any "image enhancement" modes that may be causing processing delay.

If none of the wireless methods work, check the firewall settings on the router. Sometimes, AP Isolation prevents devices on the network from seeing each other.
