Modern smartphones like the legendary Xiaomi Redmi Note 5 have long since ceased to be just a means of communication, becoming powerful multimedia centers. Often there is a need to broadcast the image from the screen of the gadget to a large display of the TV or monitor for more comfortable viewing of movies, photos or presentations. Owners of devices based on the MIUI shell can face certain nuances when searching for the wireless projection function, as its name and location on the menu changed in different versions of the firmware.
In this guide, we will discuss in detail all possible ways to activate the Wireless Display function for the Redmi Note 5 model. You will learn how to prepare for connection, what standards the device supports and what to do if standard methods do not work. Using Miracast technology allows you to transmit a video signal in high quality without the need to lay unnecessary cables.
Before you start setting up, make sure your TV also supports wireless image transfer technology. Most modern Smart TVs from Samsung, LG, Sony and other manufacturers have a built-in Wi-Fi Direct or Miracast module. If you have an old TV, you can solve the problem with external adapters such as Chromecast or Miracast-dongles, which connect via an HDMI port.
Preparation of equipment and compatibility check
The first step before setting up is to check the technical status of both devices. Xiaomi Redmi Note 5 is equipped with a Wi-Fi module that supports 2.4 GHz and 5 GHz bands, which ensures stable video streaming. However, for a successful connection, it is critical that both devices are in the zone of confident reception of the signal.
While Miracast technology theoretically allows for direct (P2P) connectivity, in practice, the router often acts as an intermediary for sharing service data, especially if DLNA protocol or specific implementations from the TV manufacturer are used.
⚠️ Warning: Make sure the TV has external device search enabled. TV It can be called Screen Share, Mirroring, or Wireless Display.
It’s also worth checking out your smartphone’s operating system version. Although the Redmi Note 5 isn’t getting major Android updates anymore, the current version of MIUI (like MIUI 11 or 12) contains the most stable drivers for wireless displays. Go to Settings → About Phone and make sure the system is updated to the latest version available.
☑️ Checking connection readiness
Search and activate functions in the MIUI system
In the MIUI shell installed on the Redmi Note 5, the wireless display feature can be hidden under different names, most commonly called "Translation", "Wireless Display" or "Cast", and can be found through the standard settings menu or through the Quick Access Panel.
The quickest way is to lower the notification curtain down and look for an icon called Translation. If there's no such icon in the visible part, click on the edit button (usually a pencil icon or three dots) and add the Translation widget to the panel. After that, just click on the icon and the system will start looking for available devices.
An alternative path through settings is as follows: go to Settings → Connection and Sharing → Broadcast. In some versions of the firmware, the path may differ: Settings → Additional Features → Wireless Display. Once the activation slider is turned on, the ether scan will begin.
⚠️ Note: If the phone says "Devices not found" after the feature is turned on, this does not always mean an error. Make sure that the TV is already running standby mode, as some TV models are only visible for search in active Screen Share mode.
Why can a function be called differently?
The process of pairing a smartphone and a TV
When both devices are ready, the connection process usually takes a few seconds. The Redmi Note 5 screen will show a list of available receivers. Find the name of your TV (usually a TV model, such as Samsung UE40 or LG WebOS) in the list and click on it.
When you connect, you may see a request for confirmation of access on your TV screen. Use the TV remote to select "Accept" or "Accept." After that, the smartphone screen will be duplicated on a large display. The image may not appear immediately, there may be a delay of 3-5 seconds.
The quality of the image you transmit depends on the power of the Wi-Fi signal. If you notice artifacts, twitches or desynchronization of the sound, try to approach the router or reduce the distance between the phone and the TV, and it is also worth closing background applications that consume traffic.
| Parameter | Optimal value | Impact on work |
|---|---|---|
| Wi-Fi range | 5 GHz | High speed, less interference |
| Distance | Up to 5 meters. | Stability of connection |
| Network loading | Minimum | No delays (lags) |
| Screen orientation | Automatic. | Proper display of content |
Configure the display and sound parameters
Once you've successfully connected, you may notice that the image on the TV doesn't take up the entire screen or has black bars on the sides.This is due to the different aspect ratio of the smartphone screen (18:9) and the TV (16:9). The streaming settings on the Redmi Note 5 often have a zoom option.
The sound is also transmitted wirelessly, and if the video is played on the phone and the sound is coming from the TV speakers, everything works correctly. However, sometimes there is a situation where the sound continues to go through the speaker of the smartphone. In this case, check the media settings in a particular application (for example, YouTube or VLC Player), where there is often a separate button for selecting the audio output device.
For games or documents, it is important to turn off the screen lock on your phone, otherwise the broadcast may interrupt after a minute. Go to Settings → Lock and Protection → Autolock and select the value of "2 minutes" or "Never" for the duration of the function.
💡
Use the horizontal orientation of your smartphone to view video. Most video services will automatically translate the image to a full screen on your TV, which will ensure maximum immersion.
Use of third-party broadcasting applications
MIUI's regular tools work well, but they're not always compatible with all TV models. If the built-in Wireless Display feature doesn't see your receiver, you should look to the trusted third-party solutions from the Google Play Store. One of the most popular is the TV Cast app or BubbleUPnP.
These apps use alternative data protocols like DLNA or Chromecast built-in, which extends compatibility. For example, Samsung TVs often have a better experience with the Smart View app (formerly Galaxy SmartView), which can be installed on the Redmi Note 5.
Installing third-party software requires permission to access the local network and media files. Once installed, launch the application, it automatically scans the network and offers a list of available devices. The connection principle is similar to the system: select the TV and start broadcasting.
⚠️ Warning: When installing free versions of broadcast apps, be prepared for the presence of advertising. For ongoing use, it is better to consider paid versions or open source analogues such as LocalCast.
The solution: Connection and quality issues
Despite the simplicity of the technology, Redmi Note 5 users may face a number of typical problems, one of the most common being a connection break after a few minutes of operation, often due to MIUI energy saving, which aggressively shuts down background processes.
To fix this, add the Translation app or player you are using to the battery exclusion list. Go to Settings → Battery and Performance → Selection of applications, find the desired application and set the No Limits mode.
Another problem is the lack of sound when watching videos due to copyright restrictions (HDCP), some streaming services (Netflix, online cinemas) block the display of protected content through Miracast on unlicensed devices or require the use of the Chromecast protocol.
💡
In most cases, connection problems are solved by restarting the router and transferring the smartphone to flight mode for 10 seconds, followed by Wi-Fi.
