How to transfer an image from Xiaomi Redmi to a TV over Wi-Fi: all working methods

Wirelessly streaming a screen from a smartphone to a big TV screen has become an integral part of the modern multimedia experience. Owners of Xiaomi Redmi devices have several technologies in their arsenal for this task, from universal Miracast to proprietary solutions like Mi Share. However, the choice of the optimal method depends on the model of the TV, the version of the MIUI firmware, and even the generation of the processor in your Redmi.

In this article, we’ll look at all the current ways to stream over Wi-Fi, including hidden settings and avoiding common bugs. You’ll learn how Screen Mirroring works on Redmi Note 12 and Redmi 9A, why some Samsung TVs refuse to receive streaming via Google Cast, and how to make DLNA work with 4K files. Particular attention will be paid to problems with audio delay and connection breaks – their causes often lie in the settings of the router.

Preparation of telephone and TV: universal requirements

Before setting up the broadcast, make sure that both devices meet the minimum requirements. MIUI is critical for Xiaomi Redmi: firmware older than MIUI 12.5 may not support Miracast for some TV models. Check the version in Settings → About Phone → MIUI version.

The situation is more complicated with a TV: cheap models without Smart TVs (such as those with the Roku TV platform or the outdated LG NetCast) often support only DLNA or require external adapters. Modern Android TV, webOS (from LG) and Tizen (from Samsung) are usually compatible with all methods, but may require special modes.

• 📱 For a smartphone: MIUI 12.5+, Wi-Fi and Bluetooth enabled (for some methods), battery charge >20%.
• 📺 For TV: support for at least one of the technologies: Miracast, Google Cast, DLNA or AirPlay (for Apple) TV).
• 🌐 Network: a router with support 802.11ac (for 4K-streams) switched off AP Isolation (customer isolation).

Pay special attention to the settings of the router: if it is enabled WPA3-Enterprise or filter MAC-The best network settings for stable flow:

⚠️ Note: If your Redmi is on a 5GHz network and your TV is on 2.4GHz (or vice versa), Miracast will not work.

Method 1: Miracast (Screen Mirroring) - Universal Protocol

Miracast is a wireless broadcast standard supported by most modern devices. On Xiaomi Redmi, the feature is called Wireless Display or Screen Mirroring, and is hidden in connection settings. The main advantage of the method is minimal latency (up to 50 ms), which is critical for games and video.

Connection algorithm:

1. Open Settings → Connections and Sharing → Wireless display.
2. Activate device search. Turn on Miracast on your TV (Samsung for Screen Mirroring, LG for Wireless Display).
3. Select your TV name from the list. Confirm the connection on both devices.

If the TV is not on the list, check:

• 🔄 Restart both devices and router.
• 📶 Make sure your phone and TV are connected to the same Wi-Fi network (not via guest access!).
• 🔧 On some Redmi models (e.g. Redmi) 10C) You need to enable Developer Mode and activate the Wireless Display option in the background.

On the Redmi Note 11 Pro+ and later, Miracast may conflict with the Game Turbo enabled. Before streaming, turn off the mode for games in the notification curtain.

3. Method 2: Google Cast (Chromecast) – for streaming content

Google Cast is fundamentally different from Miracast: it broadcasts not the screen of the phone, but specific content (youtube videos, music from Spotify, etc.). TV or through the Chromecast console).

Instructions for setting:

1. Make sure your TV has Google Home (for Android TV) installed or Chromecast installed.
2. Open a supported app (such as YouTube) on Redmi.
3. Slip on the Cast icon (usually in the upper right corner) and select your TV.

List of popular apps with support for Google Cast:

• 🎬 YouTube, Netflix, Disney+
• 🎵 Spotify, Yandex Music, VK Music.
• 📷 Google Photos (for slideshow display)
• 🌐 Chrome (browser tab broadcasting)

⚠️ Note: When streaming via Chrome to Redmi with Snapdragon processor 6xx There may be a severe drawdown FPS. For smooth flow, close all background applications.

If the Cast icon does not appear:

• Update the app to the latest version.
• Check that your phone and TV are connected to the same network (even if both devices support Guest Mode on Google Home).
• Some MIUI firmware requires enabling Local Area Media Transfer in Google settings.

4. Method 3: DLNA – for local files

DLNA (Digital Living Network Alliance) is a protocol for transferring multimedia files over a local network, which, unlike Miracast, does not duplicate the screen, but plays files directly on the TV, and is ideal for watching movies, photos and music stored on the phone.

Setting up for Xiaomi Redmi:

1. Install a file manager with DLNA support (such as Mi File Manager or Solid Explorer).
2. Open the file you want to broadcast and select Open through → DLNA.
3. Select your TV from the device list. Some Samsung J-series models may require AllShare to be pre-enabled.

DLNA limitations:

• ❌ Does not support screen broadcasting (only individual files).
• ❌ There may be problems with.mkv and.flac formats on older TVs.
• ❌ Delay in video scrolling (buffering).

Redmi with MIUI 13+ has an alternative, a built-in Mi Drive (in Settings → Connections and Sharing) that creates a local server that you can connect to from your TV via your browser.

5. Method 4: Mi Share – a proprietary solution from Xiaomi

Mi Share (formerly Mi Drop) is Xiaomi’s proprietary technology for fast file transfer and screen broadcasting between ecosystem devices, which is more stable than Miracast on Xiaomi Mi TVs, but requires the installation of proprietary software.

How to set up:

1. On Xiaomi TV, open Settings → Connections → Mi Share and turn on visibility.
2. On Redmi, go to Settings → Connections and Sharing → Mi Share.
3. Select the TV from the list and confirm the pairing through QR-code.
4. To stream the screen, tap the Screen Mirroring icon in the Mi Share interface.

Advantages of Mi Share:

• 🔹 Minimum delay (30-40 MS) when playing Call of Duty Mobile or watching video.
• 🔹 Support HDR10 compatible.
• 🔹 The ability to transfer files at speeds up to 20 MB / s (on a local network).

⚠️ Note: On Redmi with a MediaTek Helio G processor (like Redmi 10), the Mi Share may not support screen broadcasting - only file transfer.

Method 5: Third-party applications (ApowerMirror, TeamViewer)

If the built-in methods don’t work, third-party apps come to the rescue, useful for older Redmi models (like the Redmi 7) or TVs without Smart TVs.

1. ApowerMirror (for screen duplication):

• 📌 Install the application on your phone and PC/set-top box connected to the TV.
• 📌 Connect both devices to the same Wi-Fi network.
• 📌 On your phone, select M (Mirror) and scan. QR-PC-screen.

Cons: The free version adds a watermark, latency of up to 100ms.

2. TeamViewer QuickSupport (for remote control):

• 📌 Suitable for screen display, but not for video viewing (severe delay).
• 📌 Requires TeamViewer to be installed on your TV (via Android) TV prefix).

Comparison of third-party solutions:

💡

If broadcasting through a third-party app slows down, reduce the resolution of the phone’s screen to 720p developer-setting (min_width).

7 Problem Solving: Connection errors and delays

Even with the right setup, there can be common errors, and let's look at the most common ones and how to fix them:

Problem 1: The TV doesn’t appear in the list of devices.

• 🔹 Restart the router and disable Band Steering (if you have one).
• 🔹 On Redmi with MIUI 14 Try to disable Smart Wi-Fi Switching in Network Settings.
• 🔹 Update the TV firmware (on Samsung, Miracast bug fixed in Tizen 6.0)+).

Problem 2: The video is slowing down or tearing.

• 🔹 Reduce the broadcast resolution in Miracast settings (e.g., with 1080p before 720p).
• 🔹 Turn off the Adaptive Update Rate (Settings) on your phone → Display).
• 🔹 Switch to a Wi-Fi channel with less congestion (use the WiFi Analyzer app).

Problem 3: There is no sound when broadcasting.

• 🔹 Check if the phone is running No Sound or Vibration.
• 🔹 On some TVs. LG Manually select the source of sound: Settings → Sound. → Sound source → HDMI ARC.
• 🔹 For Google Cast, make sure that the app (like YouTube) doesn’t turn off sound in playback settings.

💡

If neither method works, check to see if the broadcast is blocked by an antivirus (e.g., Avast on Android TV).
