Xiaomiโs smartphones today are not just phones, theyโre full-fledged multimedia centers. But even the largest screen of the Redmi Note 13 Pro+ or Xiaomi 14 Ultra loses to a 55-inch TV when it comes to watching movies, playing games or presentations. Connecting your phone screen to TV solves this problem by turning your Mi TV or any other TV into a giant display.
In this article, weโll look at all the current ways to duplicate screens, from wireless technologies to wired adapters, and how to avoid common mistakes. Whether you want to stream YouTube to the big screen or play Genshin Impact with a gamepad, here youโll find a working solution for your Xiaomi model.
1. Wireless connection via Miracast (Wi-Fi Direct)
Miracast technology allows you to broadcast your smartphone screen to your TV wirelessly using a direct Wi-Fi channel.This method works on all Xiaomi with Android 5.0+ and is supported by most modern TVs (including Mi TV 4S/5X, Samsung QLED, LG OLED).
Main advantages:

To activate Miracast on Xiaomi:
- Open Settings โ Connections and Sharing โ Screen Transfer.

- Confirm the connection on both devices.

2. HDMI Connection: Adapters and Cables for Xiaomi
The HDMI wired method ensures a stable connection without delay, ideal for watching 4K movies or streaming games.
- ๐ adapter USB-C โ HDMI (For new Xiaomi models)
- ๐ Micro-USB cable โ HDMI (For older smartphones, for example, Redmi 4X)
- ๐ MHL-Adapter (if the TV does not support) HDMI-CEC)
Instructions for connection:
- Connect the adapter to the USB-C connector of the phone.
- Connect the adapter to the TV via HDMI-cable (use the port) HDMI 2.0 for 4K@60Hz).
- On the TV, select the appropriate HDMI-signal-input.
| Xiaomi model | Adapter type | Max, permission. | Sound support |
|---|---|---|---|
| Xiaomi 13/14 series | USB-C โ HDMI (DisplayPort Alt Mode) | 4K@60Hz | Yes. |
| Redmi Note 12/11 | USB-C โ HDMI | 1080p@60Hz | Yes. |
| POCO X5/F4 | USB-C โ HDMI | 1440p@30Hz | Yes. |
| Redmi 9A/8A | Micro-USB โ HDMI (MHL) | 1080p@30Hz | No (needs a separate audio cable) |

If the TV does not recognize the signal, try to turn on the โDevelopersโ mode โ โDebugging by USBโ in the phone settings and reconnect the cable.
USB-C โ HDMI: Features for New Models
Xiaomi smartphones based on Snapdragon 8 Gen 2/3 (for example, Xiaomi 13 Ultra or Redmi K60 Pro) support DisplayPort Alt Mode via USB-C. This allows you to transfer video in resolution up to 4K@60Hz with HDR10 support.
For activation:
- Use a certified adapter (we recommend the Anker 565 or the original from Xiaomi).
- Connect the adapter to the phone, then HDMI-cable.
- A notification will appear on the phone โ select โDisplay Modeโ.
Cheap adapters without DisplayPort support will only work in MHL mode (maximum 1080p@30Hz), even if your Xiaomi supports 4K.
โ ๏ธ Attention: On some firmware MIUI when connected through USB-C You can turn off the charging. To avoid this, use a powered hub (USB-C PD).

4. Broadcasting apps: 3 best options
If the built-in functionality doesn't work, third-party apps come to the rescue, and we tested dozens of options and selected the top.-3:
- ApowerMirror โ Supports 1080p@60Hz TV-controlled โ It works via Wi-Fi and USB โ Paid version for removing watermarks
- TeamViewer QuickSupport โ Free for personal use โ Low latency (suitable for presentations) โ Requires installation of the program on PC/TV
Chromecast
- โ Integration with YouTube, Netflix, Google Photos
- โ Simple setup
- โ Does not support screen duplication in games
๐ก
Apps like ApowerMirror consume a lot of battery. Connect your phone to charge during broadcast to avoid discharge.
5. Typical problems and their solution
Even with the right connection, errors can occur, and here are the most common ways to fix them:
| Problem. | Reason. | Decision |
|---|---|---|
| TV can't find the phone | Wi-Fi Direct or outdated firmware disabled | Update your TV and phone, turn on Wi-Fi Direct manually |
| Image brakes/tears | Weak Wi-Fi signal or high processor load | Reduce screen resolution or use a wired connection |
| No sound through HDMI. | The adapter does not support audio or incorrect settings. | Check the sound settings on your phone (HDMI as an exit) |
| Black screen on TV | Incompatible adapter or damaged cable | Try another adapter/cable, check the HDMI port on TV |
If the phone starts to warm up after connecting via HDMI, that's OK -- 4K video processing puts a strain on the processor, but if the temperature is above 50ยฐC, turn off the broadcast and let the device cool down.
โ ๏ธ Note: Some Xiaomi models (e.g. Redmi Note 10 Pro) when connected via USB-C โ HDMI This can be a heat protection system, and in this case, use a wireless method or an external fan.
6. Comparison of methods: what to choose
Which way is the best? Depends on your tasks:
- ๐ฐ Budget option: Miracast (no adapter needed) or cheap MHL-cable.
For Mi TV owners, the best choice is the built-in Miracast, as it supports HDR and has minimal latency. If you have a different brand TV, check if it supports Wi-Fi Direct or AirPlay (for iPhone, but some Xiaomi also supports).

For Miracast to work, both devices must support Wi-Fi 5 (802.11ac).
