Modern smartphones of the series Redmi TVs have powerful screens and processors, but sometimes a 6-inch diagonal isn't enough for a comfortable movie viewing experience. Wireless connection technologies make it easy to stream content from a mobile device to a large TV screen, turning your living room into a home theater. This is especially convenient when you need to share photos with guests or watch a movie from an online cinema that doesn't have a built-in app on your smart TV.
In this article, we will take a detailed look at all available synchronization methods. Xiaomi and TV over the network Wi-FiYou will learn about the shell's native functions. MIUI, using third-party apps, and setting up DLNA servers to stream video files. The correct method depends on your TV model and Android operating system version.
The main advantage of a wireless connection is the lack of unnecessary wires that can get tangled underfoot. However, for stable high-definition video streaming 4K or Full HD A good connection is required. Both devices must be on the same local network, otherwise communication between them will be impossible.
Technical requirements and equipment preparation
Before setting up, you need to make sure your equipment meets the minimum requirements for streaming multimedia content. A key requirement is a Wi-Fi module in your TV that supports these technologies. Miracast or DLNAMost modern models from Samsung, LG, Sony And Hisense have built-in protocols for receiving signals.
If your TV is not Smart, you will need an additional device such as Google Chromecast, Apple TV or a TV set-top box based on AndroidThese gadgets act as signal receivers and video stream decoders. Without them, wireless image transmission to a regular screen is impossible.
Particular attention should be paid to the wireless signal frequency. For viewing high-bitrate videos, it is recommended to use the range 5 GHz, which provides higher throughput compared to the 2.4 GHz standard.
- 📱 Redmi smartphone with Android 5.0 or higher.
- 📺 A Smart TV or external set-top box.
- 📡 A router that supports the 802.11ac (Wi-Fi 5) standard or later.
- 🔋 A charged phone battery or connection to a power bank for long sessions.
⚠️ Important: Make sure both devices have Mobile Data enabled or are connected to the same Wi-Fi hotspot. If your phone uses 4G/5G and your TV uses Wi-Fi, a direct connection may not be established without using intermediate servers.
Using the built-in "Cast" feature in MIUI
shell MIUI, installed on smartphones Redmi, has a built-in tool for wireless image output. This function is based on the protocol Miracast, which is supported by most TVs. To activate, open the Curtain Control Center and find the "Cast" icon.
Once enabled, your phone will begin searching for available devices on the network. Your TV should appear in the list. When selecting a device, a connection permission prompt may appear on the TV screen, which you'll need to confirm with the remote. Picture quality with this method is usually high, but a slight cursor lag may be experienced.
If the standard search doesn't yield any results, try accessing the advanced settings. The path to the menu may vary depending on the firmware version, but it's usually located in the Settings → Connection and Sharing → BroadcastHere you can enable the device's visibility to other gadgets.
It's important to note that when using built-in streaming, your phone's screen is mirrored on the TV. This means notifications, incoming calls, and other system messages will be visible to everyone in the room. For a comfortable viewing experience, it's recommended to enable "Do Not Disturb" mode beforehand.
Setup via Google Home and Chromecast
Ecosystem Google offers the most stable way to transfer content through the protocol Chromecast built-inTo do this, you need to install the official app on your Redmi phone. Google Home from the store Play MarketThis method is ideal for streaming video from browsers and applications that support this technology.
After installing the app, open it and find your TV in the list of devices. Click on the device icon and select "Cast Screen." Unlike Miracast, this feature uses more efficient video stream compression, reducing the drain on your smartphone's battery.
Many popular streaming services such as YouTube, Netflix And IVi, have a built-in Cast button. By clicking it, you send a video link directly to the TV, and it will automatically download the stream from the internet, without using your phone's data or resources.
☑️ Checking Google Home settings
⚠️ Please note: Application and operating system interfaces are subject to update. Button locations and menu item names may differ from those described in the instructions. Always consult the software manufacturer's latest support materials.
Streaming video via DLNA servers
To watch pre-downloaded movies stored in your phone's memory, it's best to use the technology DLNAThis protocol allows the TV to view the smartphone's media library as network storage. You don't need to mirror the entire screen; the TV will play the file automatically using its decoder.
You need to install a server application on your Redmi phone, for example, VLC for Android, BubbleUPnP or LocalCastAfter launching the app, select a video file and press the Transfer to Device button. The TV must be turned on and connected to the same Wi-Fi network.
The advantage of DLNA is that you can control playback (pause, rewind) directly from your phone, as well as use it for other tasks without interrupting your viewing experience on the big screen. Image quality is transferred losslessly, in the file's original resolution.
| Application | Supported formats | Presence of advertising | Difficulty of setup |
|---|---|---|---|
| VLC for Android | MP4, MKV, AVI, MOV | No | Low |
| BubbleUPnP | All popular | There is (in) | Average |
| LocalCast | MP4, MP3, JPG | Eat | Low |
| Xiaomi Mi Remote | Depends on TV | No | Average |
Why might the video be lagging?
Lag is often caused by Wi-Fi congestion from neighboring routers or excessive video bitrates. Try lowering the quality or switching to 5 GHz.
Solution: Connection and sound issues
Despite the ease of setup, users often encounter technical difficulties. One of the most common issues is the TV not detecting the phone. In 90% of cases, this is due to the devices being connected to different networks (for example, one to a guest network and the other to the main network) or client isolation being enabled on the router.
Another common complaint is the lack of sound when the image is successfully transmitted. This may be due to codec limitations. HDMI or Bluetooth settings. If sound is coming from connected headphones, the system may block its output to the TV. Check the audio output settings in the section Settings → Sound and vibration.
If the image is choppy or has low resolution, try reducing the load on your phone's processor by closing background apps. Also, make sure the distance between the router and your devices isn't too great and that the signal isn't being blocked by thick walls.
- 🔄 Restart the router and both devices (TV and phone).
- 📶 Check if the "Data Saver" mode is enabled on your smartphone.
- 🔒 Make sure your router doesn't block P2P connections.
- 📲 Update your YouTube app or browser to the latest version.
Alternative methods and third-party applications
If standard tools don't work or their functionality is limited, universal applications come to the rescue. Web Video Caster Allows you to stream video from websites directly to your TV, bypassing browser limitations. It automatically processes the video stream and sends it to the receiver.
For TV owners Samsung And LG there are branded applications SmartView And LG TV Plus Accordingly, they provide deeper integration, allowing you to use your phone as a remote control and even transfer files via Wi-Fi Direct without a router.
There are also paid solutions such as AirScreen (installed on Android TV), which emulate the protocol AirPlay, allowing you to connect your iPhone to your Android TV, but they also work great with Redmi phones for expanded functionality.
⚠️ Warning: Be careful when installing third-party apps from unknown sources. Download software only from the official store. Google Playto avoid the introduction of malware that can steal your data.
The impact of Wi-Fi network quality on playback
Wireless network quality is critical for uninterrupted viewing. Standard 802.11n (2.4 GHz) often fails to handle 4K video transmission, as its actual speed rarely exceeds 40-50 Mbps. For larger files, the standard 802.11ac (5 GHz).
Interference from microwave ovens, Bluetooth speakers, and neighboring routers can cause short-term connection interruptions. If you're using the 2.4 GHz band, try changing your router's broadcast channel to a less crowded one (e.g., 1, 6, or 11).
For maximum stability, we recommend setting up a static IP address for your TV in your router. This will help avoid address conflicts and speed up your phone's search for the device each time you connect. Also, make sure your router firmware is up to date.
Why can't my Redmi phone see the TV?
Most often, the problem stems from different Wi-Fi networks. Make sure your phone and TV are connected to the same router (not a guest network). Also, make sure a signal-receiving app (such as Screen Share or Miracast) is running on your TV, as many models don't scan the network in the background to save power.
Is it possible to play games on TV using your phone?
Yes, you can, using screen mirroring (Miracast). However, due to input lag, this method is only suitable for slow-paced strategy games or trivia games. For fast-paced shooters or racing games, a lag of 100-200 ms will make gaming uncomfortable. It's better to use an HDMI cable with a USB-C adapter.
Does the phone get very hot when broadcasting?
When actively streaming video, the processor and Wi-Fi module operate under load, causing the case to heat up. This is normal. For longer sessions, it is recommended to remove the case for better heat dissipation or connect the phone to a charger, as the battery may drain faster than it charges.
Is there a difference between HDMI and Wi-Fi connection?
Yes, there's a significant difference. HDMI transmits an uncompressed signal, ensuring maximum picture quality and zero lag, but it ties the phone to the TV with a cable. Wi-Fi offers freedom of movement, but quality depends on network speed, and the image may be compressed, which is noticeable on larger screens.
