You want to stream Xiaomi videos to the big screen, but you don't know how to connect your smartphone to your TV? This article will help you understand everything from choosing a cable to setting up wireless protocols. We'll look at all the current ways of connecting, including Miracast, HDMI, Google Cast and even little-known chips for older TV models.
The main advantage of Xiaomi phones (including the Redmi and POCO lines) is that it supports most modern image standards. However, not all TVs work equally well with these protocols. For example, the 2018-2020 Samsung Smart TV may not support Miracast without additional settings, and LG WebOS will require a separate application. In this article, you will find unique solutions for specific Xiaomi TV and smartphone models that are not described in the standard instructions.
Before you start, check out two key points:
- 📱 Version. MIUI On your phone (relevant to wireless methods) Outdated firmware may not support Google Cast.
- 📺 The year of the TV's release: Devices older than 2016 often require additional adapters.
1. Wireless connection via Miracast (without router)
Miracast is a point-to-point standard for transmitting images without intermediaries, built into most Xiaomi phones since MIUI 9 and works even without the Internet, the main condition is that the TV must support Miracast (usually specified in the specifications as "Wireless Display" or "Screen Mirroring").
How to check for support on TV:
- Open Settings → Network → Screen Mirroring (the name may be different).
- If there is no option, use the alternative methods below.
Step-by-step instructions for Xiaomi:
- On your phone, open Settings → Connection and Sharing → Screen Transfer.
- Select your TV from the list of available devices.
- Confirm the connection on both devices (may be required) PIN-code).
TV is included in Screen Mirroring mode
The phone has Wi-Fi and Bluetooth enabled
Distance between devices not more than 5 meters
Charge of the phone above 30% (for stable operation)
-->
Typical problems and solutions:
- 🔄 Can't find the TV: Reboot both devices and re-search. on some Redmi Note models 8/9 help VPN.
- 🎵 Sound only goes through your phone: In Miracast settings on TV, select "Output through" TV".
- 🐢 Lags and delays: Reduce screen resolution in phone settings (Settings) → Display. → Screen resolution).
Why Miracast might not work on Xiaomi Redmi 9A
Connection via HDMI (wired method)
If wireless methods are not suitable (for example, due to stability or picture quality), HDMI-cable is the most reliable option. For modern smartphones Xiaomi will need an adapter USB-C → HDMI (model USB Type-C or Micro-USB → HDMI (For older devices like Redmi 4X).
Important: Not all adapters are equally good. 4K-Choose Adapters with Support HDMI 2.0 and DisplayPort Alt Mode. Budget Chinese adapters often give the maximum 1080p.
Instructions for connection:
- Connect the adapter to the phone and HDMI-cable to adapter and TV.
- On TV, select the appropriate one. HDMI-input (usually by the Source button on the remote control).
- A request for permission to display an image may appear on the phone - confirm it.
| Xiaomi model | Type of connector | Max, permission. | Notes |
|---|---|---|---|
| Xiaomi 13/13 Pro | USB-C | 4K@60Hz | Requires an adapter with DP 1.4 |
| Redmi Note 11/12 | USB-C | 1080p@60Hz | Budget adapters may not work. |
| POCO X3/X4 | USB-C | 1440p@30Hz | It is better to use the original adapter. |
| Redmi 9A/9C | Micro-USB | 720p | Requires an active externally powered adapter |
💡
If the image on the TV is cropped or stretched, change the aspect ratio in the phone settings: Settings → Display → Aspect ratio. For most TVs, 16:9 is optimal.
⚠️ Note: When connecting through HDMI The phone will discharge faster, as the screen and external output are running simultaneously.We recommend connecting the charger to the free port of the adapter (if it supports pass-through charging).
3.Using Google Cast (Chromecast)
If you have an Android TV or a Google Chromecast, you can stream content directly from apps (YouTube, Netflix, browser) and it doesn't duplicate the screen, it just streams video, which saves battery life.
How to set up:
- Make sure your phone and Chromecast/TV are connected to the same Wi-Fi network.
- Open a supported app (e.g. YouTube).
- Click the Cast icon (usually in the top right corner) and select your TV.
List of applications with Cast support:
- 🎬 YouTube, Netflix, Disney+
- 🎵 Spotify, Apple Music (Audio only)
- 🌐 Google Chrome (Broadcasting tabs)
- 📱 Gallery Xiaomi (Photo only, no video)
💡
Google Cast consumes significantly less power than Miracast, as it only transmits the media stream, not the entire screen, and is the best choice for long-term movie viewing.
If the Cast icon does not appear:
- 🔄 Restart router and phone.
- 📱 Update the app and MIUI last-minute.
- 🔒 Check if the firewall is blocking the data transfer or VPN.
4. DLNA connection (for older TVs)
The DLNA protocol allows you to stream media files (photos, videos, music) to TVs without Smart-features.
- 📱 Mi Home (built-in function "Mediaserver")
- 🎬 BubbleUPnP (for advanced settings)
- 📺 LocalCast (supports subtitles)
Instructions for Mi Home:
- Open Mi Home → Profile → Settings → Media server.
- Turn on the option and wait for the files to be scanned.
- On your TV, open the DLNA app (may be called Media Player or Network Files) and select your phone.
DLNA limitations:
- ❌ Does not broadcast the entire screen (only individual files).
- ❌ Not all video formats are supported (for example, the video formats are not supported, MKV may not reproduce).
- ❌ Latency in video scrolling (not suitable for gaming).

5. Alternative methods for non-standard situations
If none of the above methods worked, try these solutions:
Connecting via MHL (for older Xiaomi)
MHL (Mobile High-Definition Link) technology allowed you to stream video over Micro-USB on older smartphones (Xiaomi Mi 3, Redmi 2). It is practically not used today, but if you have an ancient TV, you can find an MHL → HDMI adapter on AliExpress.
B. Use of a router with Miracast function
Some routers (e.g. Xiaomi Mi Router 4A Gigabit) support the creation of a virtual Miracast server.
- Connect your phone and TV to the same router network.
- In the router control panel, enable the Wireless Projection option.
- On your phone, choose to connect to your router as a Miracast device.
B. Live broadcast via USB (PTP/MTP)
If the TV supports USB-host, you can connect the phone with a cable and play files directly.
- On your phone, select File Transfer (MTP) mode when you connect.
- On TV, open up Media Player. → USB-device.
Disadvantage: only media files work, without screen duplication.
6. Solving common problems
Even with the right setup, you can get errors.-5 problems and solutions:
| Problem. | Possible cause | Decision |
|---|---|---|
| TV can't find the phone | Different Wi-Fi networks | Connect both devices to the same network |
| Sound's there, no image. | Incompatible HDMI adapter | Try an adapter that supports DP Alt Mode |
| Lags while watching video | Weak Wi-Fi signal | Connect to 5 GHz network or use a cable |
| Black Screen at Miracast | Locking the screen on the phone | Turn off autolock in the settings |
| No sound through HDMI. | Incorrect audio output settings | Settings → Sound → Audio output select HDMI |
Additional advice:
- 🔋 If the phone is hot when broadcasting, reduce the brightness of the screen to 50%.
- 📶 For stable Miracast, use a router with Wi-Fi 6 support (e.g. Xiaomi) AX3600).
- 🔄 If the image "breaks", try to disable Hardware acceleration in the developer settings.
⚠️ Note: On some models POCO F3/F4 post-update MIUI 14 You lose the ability to stream through Google Cast. Solution: roll back to the Internet. MIUI 13 Or use alternative apps like LocalCast.
