How to turn off dual screen on Xiaomi: all the ways for phones and TV

Double-image on Xiaomi’s screen is a common problem faced by smartphone, tablet and TV owners, with the effect of “splitting” as horizontal or vertical duplication, flickering, or splitting the screen into two identical parts, with 80% of the time faulty system settings, but sometimes the cause is hardware failures or plume damage.

This guide will work for all Xiaomi, Redmi and POCO MIUI-based devices (including versions 12-14) and HyperOS, as well as Mi Box and Mi TV Stick TV boxes. We will analyze the software and hardware methods for fixing the problem, from simply resetting the settings to checking physical connections. If after reading this article the dual screen remains, you can determine exactly whether the device needs repair.

Why Xiaomi is getting a dual screen: 6 main reasons

Before you start fixing, it's important to understand the root of the problem: image duplication rarely occurs on its own, usually preceded by specific user actions or system failures.

• 🔧 Activated screen mirror mode – the function of duplicating the screen to external devices (for example, through Miracast or Google Cast), which can crash and display the picture twice.
• 📱 Incorrect scaling settings - in MIUI there is an option Screen size, when the system fails, it can "stretch" the image with an overlay.
• 🔄 Error after firmware update – especially relevant for devices upgraded to HyperOS with MIUI 12/13.
• 🔌 Problems with TV or monitor connectivity – if you use Xiaomi as a media player HDMI or USB-C.
• 🛠️ Damage to plume or matrix – physical defects often manifest as vertical/horizontal bifurcation.
• 🤖 Third-party application conflict – some screen customization utilities (such as Second Screen or Display Changer) may break the display.

If the dual screen appeared after a phone fell, moisture hit or disassembled on its own, there is a 95% probability that the problem is hardware, and in other cases, a software solution will help.

Method 1: Disabling the screen duplication mode

The most common cause of splitting is a randomly activated mirror screen function that can turn on when you connect to a wireless display or after using Google Cast.

1. Pull down the notification bar and find the Screen Mirror (or Cast) icon. If it's illuminated, tap it to turn it off.
2. Go to Settings → Connection and Sharing → Screen Mirror and deactivate the option.
3. For Xiaomi TV consoles: press the Home button on the remote → select Settings → Display and sound → Screen mirror → turn off.

If the Cast icon is not in the curtain, but the dual image remains, try resetting your wireless connection settings:

Settings → System → Resetting → Resetting Wi-Fi, Bluetooth and mobile network settings

Turn off the screen mirror in the notification curtain

Check the Cast settings in the Connection and Sharing menu

Reset the settings of wireless networks

Reset the device-->

⚠️ Note: Some HyperOS firmwares may have the option of a Screen Mirror called Miracast or Wireless Display. If the problem persists after the shutdown, proceed to the next method.

Method 2: Reset the screen settings to factory

If the dual image appears after changing the resolution, scale or color gamut, resetting the display will help, which does not affect user data, but will return all display settings to the default values.

Instructions for smartphones and tablets:

1. Open the Settings → Display.
2. Slip on three points in the upper right corner (or additionally).
3. Select Reset screen settings (on some models, the option is hidden in the size of text and display).
4. Confirm the action and restart the device.

For the Mi Box and Mi TV Stick:

Settings → Display and sound → Additional settings → Resetting display settings

💡

If the dual image is still visible after reset, try manually changing the screen resolution in the display settings to the standard one (for example, 1080p instead of 4K).

Method 3: Checking the connection to the external display (HDMI/USB-C)

If you use Xiaomi as a media player (for example, through a HDMI-Adapter or TV connection, dual screens can be caused by permission conflicts. Here's how to fix it:

• 🔌 Turn off the cable. HDMI/USB-C Check if the problem is still on the main screen.
• 📺 Change the display mode on the TV / monitor: often helps changing from Duplicate to Extend or Second screen only.
• 🔄 Update the adapter firmware (if you use Mi) HDMI Adapter or similar).
• 🛠️ Check the cable - damaged wires can cause artifacts.

For the Mi Box and Mi TV Stick:

1. Go to Settings → Display and Sound → Screen Resolution.
2. Select the resolution that matches your native TV (e.g. 1920×1080@60Hz instead of 4K@30Hz).
3. Turn off the option Automatic Permissions.

⚠️ Note: Some Samsung TVs and LG When you connect the Mi Box, you can activate Game Mode, which duplicates the picture.

Method 4: Update firmware and reset to factory settings

If the dual screen appeared after a system update or custom firmware installation, the problem may be in a software conflict.

Update to the latest version of MIUI/HyperOS

1. Go to Settings → About the phone → System update.
2. Download and install the latest available firmware.
3. After the update, perform a soft reboot (clip Power + Volume up for 10 seconds).

B. Hard reset (if the update didn't work)

This method will delete all data from the device, so back up in advance.

1. Turn off the device.


2. Press the <power button> + <volume up> before the Mi logo appears.




3. In the Recovery menu, select →




4. Confirm the action and wait for the completion.




5. Reset the device.

For the Mi Box:

Settings → Device → Resetting settings → Full reset

💡

If the dual screen came after installing a custom recavator (TWRP) or firmware, return to the official MIUI via Fastboot.Using unstable builds often breaks the display drivers.

Method 5: Diagnostics of hardware malfunctions

If none of the software methods worked, the problem is probably physical damage.

• 🔍 Visual inspection: illuminate the flashlight at an angle on the screen – if cracks or swellings are visible, the matrix is damaged.
• 📱 Test on another device: connect Xiaomi to another TV / monitor HDMI. If the double image remains, the phone is a problem.
• 🔧 Trail check: if the screen splits when you press the case, the plume has moved away or damaged (relevant after falls).
• 🔋 Battery-free test (smartphone only): turn off the battery for 5 minutes and turn the device on from charging.

Critical information: On devices with AMOLED-screens (for example, Xiaomi 13 Pro, Redmi) K60) splitting is often associated with layer damage OLED-In this case, the repair is possible only in the service center with a replacement screen.

⚠️ Note: Do not try to disassemble Xiaomi with adhesive screen (for example, Redmi Note 12 or X-rays). POCO X5) — If you don't have any special equipment, you're at risk of permanently damaging the matrix.

Method 6: Alternative solutions for rare cases

If standard methods don’t help, try these non-obvious ways:

• 🔄 Firmware rollback: If the dual screen appears after the update, go back to the previous version MIUI via Fastboot.
• 🛠️ Replacement of the display driver: on some models (e.g, POCO F3) file-flashing persist.img through ADB.
• 📵 Use Safe Mode: Load the device in Safe Mode (Put Power on the device) → Hold the power down. → Click OK on Safe Mode. If the problem is gone, it's the third-party app's fault.
• 🔧 Screen calibration: Some devices are helped by resetting the calibration through the engineering menu (#36446337### for MIUI).

For advanced users: If you have experience with ADB, try resetting the display settings via the command:

adb shell settings put system screen_brightness_mode 0


adb shell settings put system screen_brightness 128




adb shell settings put system screen_off_timeout 30000
