You want to bring Xiaomi, Redmi or POCO to a big TV, but you don't know how to do it with HDMI? The problem is that modern smartphones have lost the classic micro-HDMI connector, and instead use USB-C or wireless technology. In this article, we will discuss all the current ways of connecting — from adapters to Miracast — and also solve the typical problems with screen resolution, audio latency and compatibility with Samsung, LG and Sony TVs.
It's important to understand that not all methods are equally convenient. HDMI-The adapter provides minimal latency and stable image, but requires the purchase of an adapter, while wireless solutions like Miracast or Google Cast are easier to set up, but can slow down when watching video in the video. 4K We tested each method on the Xiaomi 13 Pro, Redmi Note 12 and POCO F5 — See the results in the comparative table below.
If your TV is released before 2018, check if it supports HDCP 2.2 – without this protocol, secure video (for example, from Netflix or Disney+) may not play. Also note the version of MIUI: old firmware (below MIUI 12) may not have the right settings for wireless broadcasting.
1. Wired connection via USB-C → HDMI adapter
The most reliable way to display a picture from your smartphone to your TV is to use a USB-C adapter to HDMI. Suitable for all Xiaomi models released after 2019 (with a USB 3.1 Gen1 port or later). Importantly, cheap Chinese adapters often do not support 4K@60Hz and give out artifacts. We recommend original accessories from Xiaomi or certified Anker/Baseus.
What you need:
- 🔌 adapter USB-C → HDMI (Support for DisplayPort Alt Mode)
- 📺 HDMI-cable (version 2.0 or higher) 4K)
- 🔋 Power supply (if the adapter requires additional power supply)
Step-by-step:
- Connect the adapter to the USB-C port on your smartphone.
- Connect the adapter to the TV through HDMI-cable.
- Select the signal source (HDMI1/HDMI2).
- On the smartphone will appear a notification about the connection of the external display – confirm it.

If the image does not appear:
- 🔄 Restart your smartphone and TV.
- 🔧 Check the image output settings in Settings → Display. → External screen mode.
- ⚡ Connect the adapter to the charger (some models require power).
💡
If the adapter is warming up or the image is flashing, try reducing the resolution on the smartphone to 1080p in the external display settings.
2. Wireless connection via Miracast (Wi-Fi Direct)
Miracast is a wireless screen broadcast standard that supports all Xiaomi smartphones on MIUI 10 and later. The main advantage is that no wires are needed, but there are disadvantages: audio delays (up to 200 ms) and a drop in quality with a weak Wi-Fi signal. The method works on TVs that support Wi-Fi Direct or Screen Mirroring (Samsung, LG, Xiaomi TV, etc.).
How to connect:
- On the TV, activate Screen Mirroring (in the Network menu → Wi-Fi Direct or Wireless).
- On your smartphone, open Settings → Connection and Sharing → Screen Broadcast.
- Select your TV from the list of available devices.
- Confirm the connection on both devices.
Typical problems and solutions:
- 🚫 Can't find the TV: Check that both devices are connected to the same Wi-Fi network (or disconnect the smartphone from the Internet).
- 🎵 No sound: in the broadcast settings, select Enable sound on the external device.
- 🐢 Lags when watching video: reduce the resolution of the broadcast to 720p.
3. Connect via Google Cast (Chromecast or Built-in Cast)
If you have a Google Chromecast or a TV with Google Cast (Android TV, Sony Bravia), you can stream your smartphone screen via the Google Home app.This method is convenient for streaming videos from YouTube, Netflix or Kodi, but is not suitable for gaming due to high latency.
Instructions:
- Make sure your smartphone and TV (or Chromecast) are connected to the same Wi-Fi network.
- Open the Google Home app on your smartphone.
- Click on the icon of your Chromecast or TV.
- Select Translate screen → Start broadcasting.
Limitations of the method:
- 🎮 Not suitable for games (delay) >300 ms).
- 📶 Requires 5 GHz stable Wi-Fi for Full HD.
- 🔒 Some apps (such as TikTok) block the broadcast.

4. Connect via USB-OTG (for older models)
If your TV supports USB media playback and your smartphone is equipped with a USB-C or Micro-USB port, you can use a USB-OTG adapter. This method is only suitable for viewing photos, videos and music - screen broadcasting is impossible!
What do you need?
- 🔌 adapter USB-C/Micro-USB → USB-A (OTG).
- 💾 flash drive or external drive (formatted in FAT32/NTFS).
How to transfer files:
- Connect the flash drive to the smartphone through OTG-adapter.
- Copy the files you want (e.g., a movie in.mp4).
- Disconnect the flash drive and insert it into USB-television-port.
- Select the USB source on the TV remote.
💡
USB-OTG does not broadcast the screen, only allows you to view copied files. To duplicate the display, use HDMI or Miracast.
5. Solving Connection Problems
Even with the right setup, there can be errors, and we've collected the most common problems and ways to fix them:
| Problem. | Possible cause | Decision |
|---|---|---|
| No image via HDMI | The adapter does not support DisplayPort Alt Mode | Buy a certified adapter (e.g. Xiaomi USB-C to HDMI) |
| The sound is only through the phone. | In the broadcast settings, the sound on the external device is turned off | Enable HDMI audio output in Settings → Sound |
| Lags during Miracast broadcast | Weak Wi-Fi signal or network congestion | Switch to 5 GHz or reduce the resolution to 720p |
| Black screen on TV | Incompatible permission settings | Set the smartphone resolution 1920×1080 and frequency 60 Hz |
Critical information: On Samsung’s J series (2016–2017), Miracast only works after the Quick Start feature is disabled in the power settings. Some Xiaomi models (such as the Redmi 9A) do not support DisplayPort Alt Mode, only wireless methods are available for them.
💡
If only part of the screen is displayed on the TV after connecting via HDMI, zoom in the TV settings: Image → Screen size → Fit.
6. Comparison of connection methods: which one to choose?
To determine the best method, evaluate your tasks:
- 🎮 For games: only wired connection through HDMI (minimum delay).
- 🎬 For the movies in 4K: HDMI-Adapter or Google Cast (if TV supports).

|---|---|---|---|---|
| HDMI-adapter | 0-20 ms. | 4K@60Hz | No. | 500 ₽ |
| Miracast | 100-300 ms. | 1080p@30Hz | No (Wi-Fi Direct) | Free of charge. |
| Google Cast | 200-500 ms. | 4K@30Hz | Yes. | Free of charge. |
| USB-OTG | — | Depends on the file. | No. | 200 ₽ |
If you need a stable connection for work or gaming, choose HDMI. For Microsoft Google Cast HDR Dolby Vision.
7. Frequent Questions (FAQ)

🔹 Why there is no sound when connecting through HDMI?
🔹 What Adapter to Buy for Xiaomi 12T Pro?
🔹 Can I stream the screen on a Samsung TV in 2015?
🔹 Why is the image on the TV cropped at the edges?
If your Xiaomi model doesn’t support any of these methods (like very old devices like Redmi 4X), you’ll only have to transfer files over USB or use DLNA to stream media, and you’ll have to use third-party solutions like ApowerMirror to play games or mirror your screen.
