How to remove the bar at the bottom of the screen on Xiaomi devices: from TVs to smartphones

The black, gray or color bar at the bottom of the screen on Xiaomi devices is a common problem that can appear on both Mi TVs and smartphones running MIUI. In most cases, it is not a hardware malfunction, but a software failure, a display error or a consequence of incorrect settings. However, it is not worth ignoring: the band not only spoils the appearance, but can also signal more serious problems with firmware or hardware.

In this article, we will analyze all possible causes of the band – from banal (for example, the developer mode is turned on) to complex (damage to the matrix or graphics processor). You'll learn how to diagnose a problem, which settings to check first, and what to do if standard methods don't work. TV A2/L2/P1, smartphone Redmi/POCO and Xiaomi Pad tablets.

Why does the bar appear at the bottom of the screen on Xiaomi?

Before you get to the bottom of the solution, it's important to understand what you're dealing with. The bar at the bottom of the screen might be:

• 📺 Hardware - caused by physical damage to a matrix, plume or graphics chip, more common after falls or bumps.
• 🤖 Software – a consequence of a firmware failure, application conflict or incorrect display settings.
• 🔧 Systemic - appears due to the features of the shell MIUI or PatchWall (on TVs).

On Xiaomi TVs, the band is often associated with:

• 🎮 Game Mode or Dolby Vision that incorrectly scales the image.
• 📡 Incompatible settings HDMI (For example, when connecting to a console or PC).
• 🔄 Update firmware, after which the screen parameters were lost.

On the Redmi/POCO smartphones, the blame is:

• 📱 Enabled Mode for Forced-Scaling Developers.
• 🔋 Battery savings that limit performance GPU.
• 🎨 Topics or launchers conflicting with native shell MIUI.

⚠️ Note: If the band appeared after a device falls or moisture gets in, do not try to solve the problem programmatically. This may be damage to the plume or matrix - diagnostics are required at the service center.

Method 1: Checking the zoom settings (for Mi TVs)

On Xiaomi TVs, the bar at the bottom often arises from the wrong image scale, which is especially true when connected via HDMI (like a game console or PC).

1. Open Settings → Display and sound → Screen resolution.
2. Select Auto or manually set the resolution that matches your TV (e.g. 3840×2160 for 4K).
3. Go to Settings → Display and Sound → Picture Scale and select by Screen Size.
4. If external devices are connected, check their output settings (for example, on PlayStation or Xbox, turn off Overscan).

For PatchWall models (e.g. Mi TV Q2/Q1E):

• 🔍 Go to Settings. → The device → Image mode.
• 🎯 Select User and reset all settings to factory.
• 🔄 Restart the TV by holding the power button on the remote for 5 seconds.

If the band is still in, try disabling Dolby Vision or HDR in the image settings – sometimes they conflict with a signal from external sources.

Method 2: Reset screen settings on Xiaomi smartphones

On Redmi, POCO or Mi smartphones, the stripe below can be associated with:

• 📏 Incorrect scale of font or interface.
• 🎨 A design theme that is not optimized for your model.
• 🤖 Developer mode with forced-scale (force_desktop_mode).

To reset the settings:

1. Go to Settings → Screen → Text size and display.
2. Return the screen scale slider to the default position.
3. Open Settings → About the phone and 7 times click on the MIUI version to activate the developer mode.
4. Return to Settings → Additional → For developers and disable:

If the problem is in the subject of registration:

• 🎨 Go to Settings. → Topics and choose a standard theme MIUI Default.
• 🔄 Reboot the phone.

⚠️ Note: On some models (e.g, POCO F3/F4) Forced scaling can lead to artifacts not only at the bottom, but throughout the screen. If the strip is left after the switch is turned off, try resetting to the factory settings (see Method). 5).

Method 3: Update firmware and reset cache

If the band appeared after a system update or application installation, the problem may be a software conflict.

1. Firmware Update: For TVs: Settings → About TV → System Update. For smartphones: Settings → About Phone → Update MIUI.
2. Cache cleaning: On TV: Settings → Annexes → Application management → PatchWall → Clear the cache. On your smartphone: Settings → Annexes → Application management → Settings (⚙️) → Clear the cache.

Resetting graphics settings (for smartphones):

adb shell settings delete global hidden_api_policy_pre_p_apps


adb shell settings delete global hidden_api_policy_p_apps

These commands will reset the hidden API policies that sometimes conflict with the display, and they require ADB and USB debugging enabled.

For Mi TVs with PatchWall firmware, it is also recommended:

• 🔄 Restart the TV in Safe Mode (hold Menu) + Volume Down when enabled).
• 🗑️ Remove unnecessary applications that may conflict with the system.

On Xiaomi TVs with firmware older than 2021, the band at the bottom may appear due to a bug in the HDR processing module. The only solution is to upgrade to the current version of PatchWall or roll back to a stable build.

Method 4: Check Connected Devices (HDMI, USB-C)

If the band appears only when you connect to the TV external devices (set-top boxes, PC, sound panel), the problem lies in the settings HDMI or USB-C. Here is what you need to do:

• 🔌 Check the cable: Use a certified cable HDMI 2.1 (for 4K/120 Hz? USB-C DisplayPort support.
• 🎮 Set up the signal source: On PlayStation 5: Settings → Screen and video → Video output → Permission → 2160p. Xbox Series X: Settings → General. → TV and display settings → Permission → 4K UHD. On the PC with NVIDIA: Disable G-Sync in the driver control panel.
• 🔄 Reset the settings. HDMI-Port: On the Mi remote TV press Home → Settings → Devices → HDMI → Drop it.

For smartphones with DeX or DisplayPort support via USB-C:

• 📱 Connect your phone to another monitor – if the bandwidth remains, the problem is the phone.
• 🔧 In the settings USB Select File Transfer instead of Image Transfer (sometimes this resets graphic artifacts).

💡

If the band only appears in a particular app (such as Netflix or YouTube), clear the app's cache or reinstall it. Often the problem is solved by updating the app to the latest version.

Method 5: Hard Resetting and Flashing

If none of the previous methods worked, there are two radical solutions:

1. Reset to factory settings: On TV: Settings → About TV → Settings Reset → Full Reset. On Smartphone: Settings → About Phone → Settings Reset → Delete all data.

⚠️ Warning: Before reset, save important data! on Mi TVs TV This can be done through settings. → Accounts and security → Backup. On smartphones, use Mi Cloud or Google Drive.

Hand-flashing:

If the reset didn't work, we'll have to reinstall the firmware.

1. Download the official firmware for your model from the Xiaomi Firmware website.
2. For TVs: 1. Unpack ZIP-flash-stick (FAT32). 2. Connect the flash drive to the TV. 3. Go to Settings → On TV. → Updating the system → Update through USB.

Flashing is an extreme method, but it is guaranteed to eliminate software bugs. The main thing is to download the firmware exactly for your model (for example, Mi TV A2 43" and Mi TV A2 55" have different files!).

💡

If the band is left behind after flashing, it is almost certainly a hardware problem (matrix, plume or GPU).

When do I contact the service center?

There are several signs that the bar at the bottom of the screen is a hardware malfunction, and repairs are necessary:
