The Redmi Note 8 Pro is still one of Xiaomi’s most popular smartphones, thanks to the powerful Mediatek Helio G90T processor and versatile features, but even with this hardware, users face problems when trying to broadcast a screen to a TV — especially if the TV is also from Xiaomi.
In this article, we have 5 proven ways to transfer the screen from the Redmi Note 8 Pro to Xiaomi Mi TV, Redmi TV and other models (including third-party brands), analyze both wireless protocols (Miracast, Google Cast, DLNA) and wired solutions through HDMI or USB-C adapters. And also, common errors (for example, the Redmi Note 8 Pro disabled the developer mode, which causes Miracast to malfunction) and how to fix them without resetting.
1. Wireless streaming on Miracast (built-in Xiaomi protocol)
Miracast is the most native way to Xiaomi’s ecosystem, as it doesn’t require additional devices or apps. It works on a point-to-point (Wi-Fi Direct) principle, creating a direct connection between your phone and your TV. On the Redmi Note 8 Pro, the feature is hidden in the Security and Synchronization menu, not in the screen settings, as on new models.
To activate the broadcast:
- 📱 On the phone: open Settings → Connections and sharing → Broadcast (Cast).
- 📺 On TV: Go to Settings → Network and Internet → Miracast (or Wireless Projection).
- 🔄 Select the name of your TV (for example, Mi). TV 4S 55").
- ✅ Confirm the connection on both devices.

If the TV is not on the list, check:
- 🔌 Developer Mode on Phone: Go to Settings → The phone. → Version. MIUI (Tap 7 times, then in Additional settings → For developers, turn on the Wireless Display.
- 📶 Wi-Fi frequency: Miracast only works at 2.4Hz. If your router uses 5Hz, switch temporarily.
- 🔄 Updates: Redmi Note 8 Pro with MIUI 12.5 and newer Miracast is more stable.Update via Settings → Updating the system.
Why does Miracast shut down in 10 minutes?
⚠️ Note: Some Xiaomi TVs (e.g. Mi) TV Q1) Miracast is in conflict with Google Cast. Before connecting, disable Chromecast in TV settings.
2. Broadcast via Google Cast (Chromecast)
If your Xiaomi TV supports Google TV or Android TV (such as Mi TV A2 or Xiaomi TV 65 models), you can use the Google Cast protocol. Unlike Miracast, it allows you to broadcast not only the screen, but also individual applications (such as YouTube or Netflix) without delay.
Instructions:
- Make sure your phone and TV are connected to the same Wi-Fi network (required!).
- On your TV, open the Google Home app (if not, install it from Google Play).
- On your phone, swipe down the notification bar and tap the Broadcast (or Cast) icon.
- Choose your TV from the list.
The advantages of Google Cast over Miracast:
- 🎮 Less latency (important for gaming).
- 📱 Support for audio broadcast only (for example, music).
- 🔄 Ability to control playback from the phone.
| Parameter | Miracast | Google Cast |
|---|---|---|
| One Wi-Fi network is required | ❌ No. | ✅ Yes. |
| Delay (lag) | ~200 ms. | ~50-100 ms |
| Broadcasting of individual applications | ❌ No. | ✅ Yes. |
| It works on all Xiaomi TVs. | ✅ Yes. | ❌ Only with Android. TV |
⚠️ Note: If you only connect through Google Cast from your phone, check the settings of the app. For example, on YouTube, you need to manually select the playback device (TV icon in the upper right corner).
3. a wired connection through HDMI-adapter (no lags)
If wireless methods fail or you need maximum stability (for example, to watch movies in 4K or stream games), use a wired connection via the USB-C → HDMI adapter. For the Redmi Note 8 Pro, any adapter with DisplayPort Alt Mode support (for example, Baseus HDMI Adapter or the original from Xiaomi) will suit.
Step-by-step:
- Buy an adapter. USB-C → HDMI (cost ~500–1500 ₽). Cheap Chinese adapters without DisplayPort chip won’t work!
- Connect the adapter to the USB-C port on your phone.
- Connect the adapter to the TV through HDMI-cable (combined with TV).
- On the TV, select the HDMI signal source (Source or Input button on the remote).
Advantages of wired connection:
- 🎬 No delays and artifacts (ideal for gaming via Xbox Cloud Gaming or Steam Link).
- 🔊 Both audio and video are transmitted (unlike some wireless methods).
- 📶 It doesn’t depend on the quality of Wi-Fi.
💡
If the image on the TV is cropped at the edges, on the phone, open Settings → Display → Screen size and select Default or 16:9 mode.
Disadvantages:
- 🔌 The phone discharges faster (it is recommended to connect charging).
- 💰 You need to buy an adapter (but it is a one-time investment).
4. Broadcast via DLNA (for photos, videos and music)
DLNA does not transmit the entire screen, but allows you to stream media files (photos, videos, music) from your phone to your TV without wires, which is convenient if you want to show photos from your vacation or play a movie from your phone on a large screen.
How to set up:
- Turn it on on the TV. DLNA in network settings (usually Settings) → Network → DLNA/UPnP).
- On your phone, install a media server application, such as: BubbleUPnP (for power users), LocalCast (a simple interface), Mi Home (if you have a smart Xiaomi ecosystem).
📺
Choose your TV from the list.
DLNA limitations:
- 🚫 Does not transmit the phone screen (only individual files).
- 🎵 Not all video formats are supported (for example, the video formats are not supported, MKV may not reproduce).
- 📶 Requires stable Wi-Fi (with a weak signal, the video will slow down).
💡
DLNA is the best choice for viewing personal photos/video, but is not suitable for screen duplication or games.
5. Use of third-party applications (ApowerMirror, TeamViewer)
If built-in methods don't work, you can use third-party apps to broadcast the screen, and they often support additional features, such as controlling your phone from a TV or recording a screen.
Top.-3 apps for Redmi Note 8 Pro:
| Annex | Pluses | Cons |
|---|---|---|
| ApowerMirror | ✅ Low latency, support for TV management | ❌ The paid version for 4K |
| TeamViewer QuickSupport | ✅ It works over the Internet (no need for a single network) | ❌ Registration is required |
| Screen Mirroring (by Google) | ✅ Free, simple interface. | ❌ Sometimes it breaks the connection. |
Instructions for ApowerMirror:
- Install the app on your phone and TV (if there is no Google Play on TV, use the APK version).
- Run ApowerMirror on both devices.
- On the phone, tap M (Mirror) and select the TV from the list.
- Confirm the connection on TV.
⚠️ Note: Applications like TeamViewer transmit data through external servers, and do not use them to broadcast sensitive information (passwords, banking applications).
6. Solving typical broadcasting problems

Problem 1: The TV doesn’t see the phone in the list of devices.
- 🔄 Reboot both devices.
- 📶 Check that your phone and TV are connected to the same Wi-Fi network (even for Miracast!).
- 🛠️ Update the TV firmware (Settings) → Update of the PO).
Problem 2: There is an image, but no sound.
- 🔊 On your phone, open the notification panel and check that the sound is transmitted to the TV (dynamic icon).
- 🎵 In some applications (for example, YouTube) you need to manually select the playback device.
- 🔌 If you use HDMI-Adapter, try another cable (sometimes contact issues).
Problem 3: Lags and stuttering videos.
- 📶 Switch the router to 5 Hz (if the TV supports).
- 📱 Close the background apps on your phone (especially instant messengers and games).
- 🔄 Reduce the broadcast resolution in Miracast settings (e.g., with 1080p before 720p).
