Broadcasting from Xiaomi Redmi to TV: a complete guide to Wi-Fi

Modern Xiaomi Redmi smartphones have powerful displays, but sometimes you want to share a vivid experience with friends on the big screen. Fortunately, wireless data technology allows you to easily display an image from your device to your TV using only your home Wi-Fi network. This eliminates the need to search for HDMI cables and additional adapters, turning the living room into a full-fledged media center in seconds.

Owners of devices based on the MIUI shell or the new HyperOS have access to built-in broadcast tools that do not require the installation of third-party software. However, the process may differ depending on the model of your TV and the version of the operating system. In this article, we will discuss all the current methods, from regular Translation to third-party applications, so you can enjoy the content in the maximum quality.

Before you start, make sure that both your smartphone and your TV are connected to the same wireless network. This is a critical condition without which device detection is impossible. If the router supports dual-band (2.4 and 5 GHz), it is advisable that the gadgets be connected to the same frequency for stability of the connection.

Compatibility check and network preparation

Successful synchronization is directly dependent on the stability of the local network, and many users ignore this stage and then wonder why the TV can't see the phone or why the video is twitching. The Miracast and DLNA protocols used for transmission are sensitive to interference and channel congestion.

First, check your router settings. If you have a dual-band router, make sure that Xiaomi Redmi and Smart TV are connected to the same network, even if they are called the same. Sometimes routers create separate guest networks or isolated VLANs that block direct connection between devices inside the house.

Also worth updating is the TV firmware. Manufacturers often add support for new codecs and fix wireless protocol errors through updates. Go to your TV's settings menu and find the software update.

⚠️ Note: If your router is in Guest Network mode, devices may be isolated from each other for security reasons.

For quick diagnosis, you can use a built-in speed test or just try to open a heavy page on both devices. If the Internet is unstable, it is better to postpone the broadcast or go closer to the router.

The standard "Translation" function in MIUI and HyperOS

The easiest and fastest way to display the screen is to use the built-in feature of the system, which is called Translation or Cast in Xiaomi shells, which implements Miracast technology, which allows you to duplicate images from your phone to your TV in real time.

To activate the mode, drop the swipe notification curtain from top to bottom. Find the Translation icon. If it's not on the first page, click the edit button (usually a pencil icon or three dots) and drag the icon to the active area. Once turned on, the system will start searching for available devices.

A request for confirmation of connection may appear on the TV screen. Some Smart TV models require you to click the Accept or Confirm button on the remote, and after successful pairing, the smartphone screen will fully appear on the large panel.

It's worth noting that this method can heat up your phone because it's actively encoding the video stream, and if you're planning to watch a movie that lasts more than two hours, it makes sense to plug the device into charging.

⚠️ Note: When you duplicate the screen through Miracast, the proportions may not match. If the phone has navigation buttons on, they will also be visible on the TV, which may overlap part of the image.

Broadcasting through video services (YouTube, Netflix)

If your goal is to watch a particular movie or video, rather than duplicate the entire screen of your smartphone, you’d better use the built-in Cast feature inside apps, which is the most energy-efficient method, since the phone acts only as a remote control, and the video is downloaded by the TV directly from the network.

Open an app like YouTube or Netflix and find a livestream icon (a rectangle with Wi-Fi waves in the corner) and click on it and select your TV from the list. The video will run on the big screen, and you can continue to use your phone for calls or correspondence.

The advantage of this method is the high quality of the picture and the absence of delays that are possible when duplicating the screen.

It's important to understand the difference: when you're duplicating a screen (Miracast), the phone encodes the picture and sends it. When you stream it through an app (DLNA/Chromecast built-in), the phone just tells the TV, "Put this video on this link." So in the second case, the quality is often higher.

Using the Mi Remote application for management

Xiaomi smartphones have a unique advantage – the built-in infrared port (IR Blaster) of most Redmi models, which allows you to use the phone as a universal remote, even if the TV is not connected to Wi-Fi, although for broadcast functions you will still need a network.

The Mi Remote app is pre-installed on the system. Launch it, add your TV by selecting a brand from the list. Once set up, you can control the volume, input and menu of the TV directly from your smartphone screen.

While Mi Remote primarily emulates an IR remote, in modern versions it also knows how to find devices on the network for fast transfer of photos and videos, which is convenient if the standard Translation function for some reason is unstable.

Alternative apps: AllCast and TV Cast

If Xiaomi’s regular funds don’t see your TV, third-party solutions will come to the rescue, and popular apps like AllCast or BubbleUPnP work perfectly with the DLNA protocol supported by most Smart TVs.

The way it works is simple: you install an app on your phone, open a video file or a photo in a gallery, select Send and point the TV, and the app will convert the stream into a TV format that you can understand.

The feature of these programs is the ability to play files from cloud storage or NAS local network, which expands the capabilities of the media center, but free versions often have time limits or contain advertising.

💡

Expert advice: To view local video files in high bitrate (for example, 4K HDR), it is better to use a bundle of VLC Player on your phone and TV, or the SMB protocol, which is built into the MIUI file manager.

When using third-party software, make sure you have given the necessary permissions to access the local network. Android 13 and above (and HyperOS) need to manually allow applications to access devices on the local network when you first start.

Solving Connection and Delay Problems

A common problem is desynchronizing audio and video or twitching images periodically, which almost always indicates a Wi-Fi bandwidth problem. Try restarting the router by turning it off power for 10 seconds.

Also check if the phone is running background downloads. If the background is swinging updates to a game or app, bandwidth may not be enough for the video stream. Close unnecessary processes through the menu of recent apps.

If nothing helps, reset the network settings on your phone. Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. This will delete saved passwords, but often resolves problems with the wireless module drivers.

⚠️ Note: When you reset your network settings, you will lose your saved Wi-Fi passwords. Make sure you remember the data to connect to your home network, or it is stored in your account. Mi/Google.

In some cases, change helps. DNS-Try to write static addresses 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare) to speed up the resolution of domain names when streaming.

💡

Connection stability is more important than maximum speed, low ping and no packet loss are more important for video broadcast than the 100 Mbps claimed by the provider.
