How to disable screen split on Xiaomi devices: TVs and smartphones

Splitting screens on Xiaomi devices is a useful feature for multitasking, but sometimes it is activated accidentally or starts to malfunction. Users are faced with a situation where the screen is divided into two parts for no apparent reason, and it is impossible to return the standard display mode. In this article, we will discuss all possible ways to remove screen separation on Mi TVs, Redmi Smart TVs and Xiaomi smartphones, and explain why this happens.

The problem can be different, from random gestures to software failures after an update, and some users confuse splitting the screen with Picture-in-Picture (PiP) mode or display errors when connecting external devices, and we can help you identify the cause accurately and find a solution.

Reasons for the appearance of screen splitting on Xiaomi

Before trying to remove the separation, it's important to understand why it came about.

• 🤏 Random gesture. On Xiaomi smartphones, splitting the screen can be triggered by swiping up from the bottom panel with a delay. On TVs, by pressing the Home or Menu button long term.
• 🔄 Failure after software updates. Often the problem occurs after an automatic update MIUI or PatchWall (shells for TV). For example, versions MIUI 14 and PatchWall 3.0 had bugs with multiwindow.
• 🎮 Connect external devices: If a computer, console, or smartphone is connected to a TV using HDMI, some modes (e.g., Duplicate or Extend) can simulate separation.
• 🛠️ Special Mode Activation. Xiaomi TVs have a "Multi-Screen" feature for displaying two sources simultaneously (e.g., HDMI1 + TV). It can turn on randomly.
• 🤖 Application failures: Some programs (e.g. YouTube, Netflix, or Mi Video) can force the separation mode to be activated when content is played.

If the splitting has occurred without your participation, first check whether external gadgets (keyboard, mouse, game console) are connected to the device, sometimes the signal from them can be interpreted by the system as a command to activate multiwindow mode.

How to remove screen split on Xiaomi TV

On Mi TVs and Redmi Smart TVs, splitting the screen is most often due to a multiscreen feature or a PatchWall glitch. Here are the step-by-step instructions for different situations:

Method 1: Disabling Multi-Screen Mode

If the screen is split into two parts with different signal sources (e.g., HDMI left, TV right), follow these steps:

1. Press the Menu button on the remote.
2. Go to Settings → Display and Sound → Multiscreen.
3. Select the option “Disable Multi-Screen” or “Single Screen”.
4. Confirm the action with the OK button.

If you don't have a "multi-screen" item on the menu, it's a different one. Try the next one.

Method 2: Reset the display settings

A failure in the display settings can force the screen to split, to reset them:

1. Open Settings → System → Reset and Recovery.
2. Select Reset Image Settings (not to be confused with a full reset!).
3. Confirm the operation, the TV will reboot.

⚠️ Warning: This method won't delete your apps or accounts, but it will return the brightness, contrast, and screen modes to factory settings. If the problem persists after the reset, a hardware failure may be the cause.

Method 3: Restart the TV in Safe Mode

If the split screen is caused by a firmware failure or application conflict, restarting in Safe Mode will help:

1. Press and hold the Power button on the remote for 5-7 seconds.
2. In the menu that appears, select "Reboot in Safe Mode".
3. After the reboot, check if the partition has disappeared. If so, the problem is in one of the installed applications.

Only system applications are running in Safe Mode. If the screen is back to normal, remove newly installed programs (especially those related to video or streaming).

How to disable screen split on Xiaomi smartphone

On Xiaomi smartphones (Redmi, POCO, Mi series), the split screen is activated via multi-window mode or gestures.

Method 1: Closing the multi-window mode through the notification panel

If the screen is divided into two parts with different applications:

1. Swipe your finger down to open the notification panel.
2. Find a notification that says “Multi-window active” or “Screen split”.
3. Tap it and select "Close" or "Exit".

If there is no notification, try swiping the dividing line up or down – sometimes this closes the mode.

Method 2: Disabling the split screen gesture

To avoid accidentally activating the separation, turn off the corresponding gesture:

1. Go to Settings → Additional → Special Features → Screen split gestures.
2. Turn off the slider next to the "Screen split" option.

On some models, the path may differ: Settings → System → Gestures → Screen split.

Method 3: Forced closure of applications

If splitting the screen is caused by a crash in an app (like YouTube or Chrome), shut it down forcibly:

1. Open Settings → Applications → Application Management.
2. Find the problem app and select Forced Stop.
3. Reboot your smartphone.

⚠️ Warning: If the split screen reappears after the reboot, the cause may be a damaged firmware, in which case only flashing through Fastboot or contacting the service center will help.

Screen splitting due to external devices: what to do

If external gadgets (keyboard, mouse, game console) are connected to a TV or smartphone, they can send signals that activate split screen. For example, on Xiaomi TVs, the Win + P key combination (if the keyboard is connected) can switch display modes.

To rule out this cause:

• 🔌 Disconnect all devices from HDMI, USB and Bluetooth ports.
• 🔄 Restart the TV or smartphone.
• 🎛️ Check if the separation has disappeared. If so, connect the devices one at a time to identify the culprit.

The most frequent "provocateurs":

If the problem occurs when connecting to Mi TV Stick or another console, try changing the HDMI- port on your TV or using the HDMI 2.0 → HDMI 1.4 adapter (sometimes helps with protocol version conflicts).

Updating the firmware as a solution to the problem

If the split screen appeared after the update or is a system bug, check the relevance of the firmware. On Xiaomi TVs, the multi-window failures were recorded in PatchWall versions:

• 2.0.128 – Forced division bug when HDMI is connected
• 3.0.45 – random activation of the mode when watching YouTube;
• 4.0.15 – Display error when using Google Cast

To update the firmware on the TV:

1. Go to Settings → About TV → System Update.
2. Click "Check Updates."
3. If a new version is available, install it and restart the device.

On smartphones, update MIUI via Settings → About Phone → System Update. If the update doesn’t work, try rolling back to the previous version (instruction below).

💡

Before updating your firmware on your Xiaomi TV, turn off all external devices and make sure the network connection is stable.

Removing the firmware to the previous version

If the split screen appears after the update, you can go back to the old version of PatchWall or MIUI.

1. Download the required firmware version from the official Xiaomi website (Support → Downloads section).
2. Copy the file onto a flash drive and connect it to the TV.
3. Go to Settings → About TV → Local Update.
4. Select the downloaded file and confirm the installation.

⚠️ Warning: Rolling back the firmware will reset some settings (e.g., saved Wi-Fi networks). On smartphones, rollbacks may require unlocking the bootloader, which will void the warranty.

Hardware reasons for screen splitting

If the software methods don't work, the problem may be the hardware.

• 🔧 Display plume damage (relevant for smartphones) Symptoms: splitting the screen is accompanied by artifacts or broken pixels.
• 🔌 Malfunction HDMI-For example, oxidation of contacts or mechanical damage.
• 🔋 GPU failure (rare but found on older Mi models TV).
• 📡 Interference from other devices, for example, if a powerful router is running nearby at 5 GHz.

For diagnosis:

1. Connect the TV to another power source (exclude socket problems).
2. Try using another HDMI- cable (preferably High Speed certified).
3. If you are on a smartphone, check if there have been any falls or bumps (especially in models with AMOLED- screens).

If the split screen is accompanied by flickering, stripes or spontaneous reboots, the device should be shown at a service center, which can be a sign of damage to the motherboard or graphics chip.
