How to create a second screen on Xiaomi devices: 5 proven ways

Adding a second screen to Xiaomi devices opens up new possibilities for multitasking, presentations or entertainment. Whether you want to duplicate an image on a TV, expand the workspace on a monitor or use a smartphone as an additional display for the PC โ€“ modern Xiaomi gadgets support these functions at the hardware level. In this article, we will discuss all the current ways to create a second screen for different types of devices: smartphones on MIUI, Mi TVs, and even for Mi TV Stick.

Itโ€™s important to understand that image transfer technologies depend on the device model and firmware version. For example, Xiaomi 13 Pro and Redmi Note 12 smartphones support Miracast and Wireless Display, while budget models may require additional adapters. We will look at both wireless and wired methods, and provide recommendations for solving typical connection problems.

1. Wireless screen duplication on TV (Miracast/Wi-Fi Direct)

The most popular way to create a second screen is to use the built-in Miracast wireless broadcast feature, which works on all Xiaomi smartphones with MIUI 12 and later, and is supported by Mi TVs and Redmi Smart TVs. The main advantage is the lack of wires and minimal delays when watching videos.

To activate the broadcast:

  • ๐Ÿ“ฑ Open the Settings. โ†’ Connection and sharing โ†’ Broadcasting the screen on a smartphone
  • ๐Ÿ–ฅ๏ธ On the TV, go to Settings. โ†’ Network โ†’ Wi-Fi Direct or Screen โ†’ Wireless display
  • ๐Ÿ” In the list of available devices, select your Xiaomi TV
  • ๐Ÿ”„ Confirm the connection on both devices (may be required) PIN-code)
๐Ÿ“Š What is the way you connect the second screen more often?
Wireless (Miracast/Wi-Fi Direct)
Wire (HDMI/USB-C)
Through special applications (ApowerMirror)
Never plugged in.

When you first connect, the system may ask permission to access media โ€” be sure to confirm it. Otherwise, the broadcast will only work for system applications. The latency on this connection is usually 50-100 ms, which is invisible when watching movies, but can interfere with games.

โš ๏ธ Note: Xiaomi TVs older than 2019 may not support Miracast in extended screen mode.

2. Wired connection via HDMI or USB-C (DisplayPort Alt Mode)

For minimal latency and maximum image quality, it is recommended to use a wired connection. Modern Xiaomi smartphones (starting with the Mi 10 and Redmi K30 Pro) support the DisplayPort Alt Mode standard via a USB-C port. This allows you to display the image in resolution up to 4K@60Hz when using a quality cable.

You'll need:

  • ๐Ÿ”Œ adapter USB-C โ†’ HDMI (We recommend original Xiaomi accessories or certified USB-IF)
  • ๐Ÿ“บ Television or port monitor HDMI 2.0 or newer
  • ๐Ÿ”‹ Power supply for a smartphone (with prolonged use)

Check DisplayPort support on your smartphone (list of models below)

Buy an adapter USB-C โ†’ HDMI supportive 4K

Connect the adapter to the smartphone before the connection HDMI-cable

Configure the display mode in the developer parameters (if required)-->

Once the adapter is connected, the system will automatically detect the external display, and in some cases, you may need to manually adjust the resolution:

  1. Go to Settings โ†’ Display โ†’ Additional settings
  2. Select HDMI Mode or External Display
  3. Set the optimal resolution (recommended 1920ร—1080@60Hz for stable operation)

Redmi Note 12 Pro+Yes.1080p@60HzHDR support for original cable

Xiaomi 11 LiteNo.โ€”Only wireless methods

3.Using the Mi TV Stick or Mi Box as the second screen

If your TV doesn't support Miracast, you can use the Mi TV Stick or the Mi Box S as a middleman, and these devices convert any TV with an HDMI port into a wirelessly enabled smart display, a technique that's particularly relevant for older TVs or projectors.

Instructions for setting:

  1. Connect Mi TV Stick to TV and set it up via Google Home app
  2. On the Xiaomi smartphone, activate the broadcast mode (Settings โ†’ Screen โ†’ Broadcast)
  3. In the list of devices, select your Mi TV Stick (the name will contain a prefix) Mi_)
  4. Confirm the connection and select the display mode: Duplicate or Expand

๐Ÿ’ก

To reduce the delay of the broadcast via Mi TV Stick, turn off the feature "Auto-optimize the image" in the settings of the device. This will reduce buffering by 20-30%.

Important feature: Mi TV Stick 2nd generation (model MDZ-26-AB) supports broadcasting in resolution up to 1080p, while the original version is limited to 720p.

4. Configure the second screen through applications (ApowerMirror, TeamViewer)

When the built-in MIUI tools are not suitable (for example, for remote control or specific tasks), you can use third-party applications.

  • ๐Ÿ–ฅ๏ธ ApowerMirror โ€“ supports both duplication and extended mode with mouse control
  • ๐ŸŒ TeamViewer QuickSupport โ€“ for remote technical support with a second screen
  • ๐ŸŽฎ Steam Link โ€“ optimized for streaming games from PC to phone or TV

Example of settings through ApowerMirror:

  1. Install the app on your smartphone and PC/TV with Android TV
  2. Connect both devices to the same 5GHz Wi-Fi network (important for minimal latency)
  3. On your smartphone, select the mode USB-debugging or wireless connection
  4. Scanner. QR-PC code syncs devices automatically

โš ๏ธ Note: ApowerMirror applications can request permissions to access notifications and geolocation, and it is not recommended to refuse these permissions, this will lead to a breakdown of the connection each time. 5-10 minute.

5. Advanced Desktop Mode on MIUI (for productivity)

The Extended Screen feature in MIUI 14 allows you to use your smartphone as a second monitor for your PC or tablet, which is particularly useful for document management, programming or design.

  • ๐Ÿ’ป Windows computer 10/11 or macOS Monterey and newer
  • ๐Ÿ“ฒ Xiaomi Smartphone with Xiaomi MIUI 14+ support USB 3.1
  • ๐Ÿ”Œ Cable USB-C โ†’ USB-C Data transmission support (not all cables are suitable!)

Step-by-step:

1. Connect your smartphone to your PC via USB-C


2. On your smartphone, select File Transfer (MTP) mode




3. On PC, install ADB drivers (if not installed)




4. Enable "Developer Mode" on your smartphone:




Go to Settings โ†’ About the phone โ†’ MIUI version




Press 7 times on "Version MIUI"




5. In the developer settings, activate:




- USB debugging.




Allow ADB debugging in Charging Only mode




6. Use the scrcpy program to display the screen:




- Launch commands:


     scrcpy --window-x 0 --window-y 0 --window-width 1280 --window-height 720
How to check the speed USB-connection?
Connect your smartphone to your PC and execute the command in the terminal (Windows): adb shell cat /sys/class/usb/usb1/speed The result "5000" means USB 3.0 (enough for Full HD), "480" - USB 2.0 (lags will be).

6. Resolving typical connection problems

Even when you set it up correctly, you can get errors, and we've put together solutions for the most common cases.

Before resetting your settings, write down your Wi-Fi passwords โ€“ they will be deleted from both devices!

FAQ: Frequent questions about the second screen on Xiaomi

Can you use a Xiaomi smartphone as a second screen for a MacBook?
Yes, it's a Duet Display or Sidecar app (in macOS Catalina and later), and you'll need a USB-C โ†’ Lightning cable (for iPhone) or a USB-C โ†’ USB-C (for Android), and the latency is minimal, around 30-40 ms.
Why is there no audio on Xiaomi TV via Bluetooth headphones?
This is a limitation of the MIUI architecture. When the screen is broadcasted actively, the audio stream is redirected to the main output device (TV). Solution: connect the headphones directly to the TV or use a wired smartphone connection via USB-C โ†’ 3.5 mm jack adapter.
How to turn on the "Advanced Screen" mode instead of duplication?
In most cases, MIUI automatically prompts you to select the mode when you first connect. If the window does not appear: Open the notification bar during the broadcast Click on the notification Broadcast the screen is active Select Extended Mode (or Second Screen in English firmware) On some models (for example, POCO X5) this mode is only available after activation in the Developer Settings.
What is the maximum resolution supported in wireless broadcasting?
Depending on the device model and the Wi-Fi standard: Xiaomi 13/14 series: up to 4K@30Hz (when using Wi-Fi 6) Redmi Note 11/12: up to 1080p@60Hz POCO M5/M6: up to 720p@30Hz For stable 4K, a wired connection via USB-C โ†’ HDMI is recommended.
Can I stream Xiaomiโ€™s screen on a Samsung TV?
Yes, but with reservations: Samsung TVs 2018 and newer support Miracast through the Screen Mirroring feature On TVs 2016-2017 may require Mi TV Stick or Chromecast For models older than 2016, the only option is a wired connection via HDMI adapter Before connecting, update the TV firmware to the latest version.
