Modern Xiaomi and Redmi smartphones have powerful multimedia capabilities that make it easy to share content on the big screen. Wireless broadcasting HDMI has become the de facto standard for viewing photos, videos, and presenting presentations. Users no longer need to search for HDMI cables or adapters if both devices are connected to the same network.
In this article, we'll take a detailed look at how to stream content from your phone to your TV via Redmi Wi-Fi using built-in MIUI or HyperOS features. You'll learn the intricacies of these protocols. Miracast And DLNA, as well as how to resolve common connection issues. Proper setup will ensure a high-quality image without lag.
It's worth noting that the menu interface may differ slightly depending on the operating system version. However, the basic operating principles remain the same for most models, whether it's a budget Redmi Note or a flagship Xiaomi. Let's look at the basic connection methods.
Hardware and network requirements
The first and most critical condition for successful synchronization is that the devices are located on the same local network. Router It must correctly distribute IP addresses to both devices. If your phone is connected to 4G/5G mobile internet and your TV is connected via cable or other Wi-Fi, the connection will fail.
⚠️ Important: Make sure that the "AP Isolation" feature is not activated on your router, which prevents devices within the network from seeing each other.
The quality of the wireless signal directly impacts the stability of the video stream. For transmitting Full HD or 4K content, it is recommended to use a frequency 5 GHz, which provides higher throughput compared to the standard 2.4 GHzThis is especially important if you plan to stream heavy files or play games.
TV compatibility also plays a role. Most modern Smart TVs support the technology. Miracast (Wireless Display) "out of the box." If you have an older TV model without Smart functions, you will need an additional adapter, for example, Chromecast or AnyCast, which connects to the HDMI port.
- 📡 The Redmi smartphone and TV must be connected to the same router.
- 🔌 For older TVs, you need an HDMI adapter with Wi-Fi support.
- ⚡ It is advisable to use a dual-band router (5 GHz) for stability.
Using the built-in Broadcast feature
MIUI and HyperOS have a built-in screen mirroring tool. To activate it, pull down the notification shade and find the icon. Broadcast (Cast). If it's not on the visible toolbar, click the edit button (usually a pencil or three dots) and add this shortcut from the list of available ones.
Once enabled, your phone will begin searching for available devices within range. A connection confirmation prompt may appear on the TV screen; accept it with the remote. Response time is typically between 3 and 10 seconds.
If the automatic search does not yield any results, you can use the settings menu. Go to Settings → Connection and Sharing → BroadcastA more detailed list of devices and connection status is often displayed here. In some firmware versions, this feature may be called "Wireless Monitor."
☑️ Check before connection
It's important to understand the difference between the operating modes. In mirroring mode, absolutely everything that happens on the smartphone screen is displayed on the TV, including notifications and system sounds. This is convenient for demonstrating the interface, but it uses more power.
Broadcast via Mi Remote app and Chromecast
An alternative and often more stable way is to use technology Google CastMany modern TVs have built-in Chromecast. This means you don't need to mirror the entire screen; you can stream content directly from apps.
Open the app YouTube, Netflix or any video player on your Redmi phone. Find the rectangle icon with waves (the broadcast symbol) in the corner of the video. Tap it and select your TV from the list. The video will start playing on the TV, and you can use your phone as a remote control.
⚠️ Please note: When using Google Cast, your phone only acts as a remote control. If you close the app on your phone or the battery runs out, playback on your TV may be interrupted.
For TVs without built-in Chromecast, you can use the app Mi Remote (if there is an IR port) or third-party utilities like Web Video CasterThey allow you to forward a link to a video file directly to the TV's browser, bypassing the load on the smartphone's processor.
Why is the sound delayed?
Audio lag (desync) is often caused by Wi-Fi congestion from neighboring routers. Try switching your router to a different channel in the settings or using 5 GHz.
The advantage of the Chromecast method is that the phone doesn't heat up as much as with full mirroring. The processor decodes the stream but doesn't constantly render the entire system interface. This extends the device's battery life.
Third-party screen mirroring apps
When standard methods don't work or the functionality isn't sufficient, third-party solutions come to the rescue. The market leader is the app ApowerMirror, which allows you not only to broadcast your screen, but also to control your phone from a PC or TV using a mouse.
Another popular program is TeamViewer QuickSupport or AnyDeskAlthough they're designed for remote access, their screen sharing feature often works where standard protocols fail. Installing such applications requires permission to "draw on top of other windows."
| Application | Connection type | Delay | Paid features |
|---|---|---|---|
| Mi Cast (Standard) | Miracast | Low | No |
| Google Home | Chromecast | Average | No |
| ApowerMirror | Wi-Fi / USB | Low | Yes (advertising, watermarks) |
| LocalCast | DLNA | Absent | There are (topics, advertising) |
When using third-party software, carefully monitor security permissions. The app may require access to the local network and microphone (to transmit audio from the phone, unless it's transmitted via the video channel). Always download apps only from the official store. Google Play.
Setting up DLNA for multimedia
Protocol DLNA Ideal for viewing photo galleries and video archives stored on your phone. Unlike Miracast, it doesn't broadcast images in real time, but rather transmits a media file for playback.
Redmi phones often have a built-in video player that supports DLNA. Open a video file, click the "Cast" button or the device icon, and select your TV. The TV will act as the client, and the phone will act as the server.
For more flexible management of your media library, you can install the application BubbleUPnP or use the built-in file manager ConductorYour TV should appear in the "Network" or "Remote Devices" section. This allows you to open files directly from the file manager interface on the big screen.
⚠️ Please note: Smart TV and mobile app interfaces are frequently updated. The location of the casting buttons may change. If you don't find the option you need, check the "About TV" or "Help" section in the device menu.
The main advantage of DLNA is the ability to turn off your smartphone's screen or minimize the app, and the video will continue playing on your TV. In this case, the phone acts as a remote control, saving battery life.
Troubleshooting connection issues
A common problem is when a phone simply "doesn't detect" the TV. In 90% of cases, this can be resolved by rebooting the router. The network settings cache can become full, causing the device to stop broadcasting its discovery services correctly.
Another cause is different frequency bands. If the router broadcasts two networks with the same name (Smart Connect), the devices may be on different subnets. Try temporarily separating the 2.4 GHz and 5 GHz networks by giving them different names, and connect both devices to one of them.
If the image is choppy or has low resolution, check your bandwidth. Downloading large files on other devices on the network can choke the video stream. Also, try lowering the streaming quality in the app settings or reducing the screen resolution. Settings → About phone → MIUI version (press and hold) → Advanced settings → Minimum width (be careful, requires knowledge).
In rare cases, the problem lies with your antivirus or router firewall, which blocks the ports required for Miracast. Try temporarily disabling traffic filtering or Parental Controls, if enabled.
Comparison of connection methods
The choice of method depends on your goals. For gaming and browsing, native streaming (Miracast) is best, as it ensures minimal input lag. For watching movies from online cinemas, Chromecast is ideal, as it reduces the load on your phone.
For showing photos to guests, DLNA or a built-in gallery with a "Stream" button is the most convenient, as this allows you to freely walk around the room with your phone without interrupting the slideshow on the screen.
Keep in mind that wireless streaming is a power-consuming process. The Wi-Fi module operates at full power, and the screen (in mirroring mode) remains lit constantly. It's recommended to keep your phone close to a charger or use a power bank.
Why isn't my TV showing up in the list of devices?
Make sure the wireless connection app (often called Screen Share, Miracast, or Wireless Display) is running on your TV. On some Samsung models, this is Source -> Screen Mirroring; on LG models, this is Input -> Device Connector. Without active standby mode, the TV is invisible to your phone.
Is it possible to stream audio only to a TV?
Yes, when using Miracast or Chromecast, audio is sent to the TV by default. If the audio is coming from your phone, check the volume settings in the notification shade or in the app itself (for example, in YouTube, select the audio output device).
Does broadcasting affect internet speed?
When using Miracast (screen mirroring), the internet is not used; data is transferred locally between the phone and TV via the router. Using Chromecast or online movie theaters consumes bandwidth because the TV downloads video from the internet.
How do I turn off the broadcast?
The easiest way is to tap the "Stop" button in the floating window on your phone's screen or in the notification shade. You can also simply turn off Wi-Fi on your smartphone or select "Disable" in the broadcast menu.
