Black bars on the sides of the screen, cropped interface elements or text that is too small - many smartphone owners face these problems Xiaomi, Redmi i POCO. The reasons may be different: from incorrectly selected resolution to software failures after the update MIUI. In this article, we will look at all the working ways to stretch the screen on Androiddevices, including hidden developer settings and solutions for specific models. Xiaomi, including hidden developer settings and solutions for specific models.

It is important to understand that not all methods are universal. For example, on POCO F3 the scaling algorithm differs from Redmi Note 10 Pro due to different processors and firmware versions. We've tested each method on current devices (2023-2026) and pointed out where caution is required. If after the changes the image becomes blurry or artifacts appear, do not panic: at the end of the article there is a section about returning to standard settings.

Why the screen on Xiaomi does not stretch automatically

The problem with cropping or black bars (letterboxing) is usually associated with a mismatch in the aspect ratio of the screen and the content. Here are the main reasons:

  • 📱 Hardware limitation: some applications (especially games and streaming services) fix the resolution to standard 16:9, although modern ones Xiaomi have a ratio 20:9 or 21:9.
  • 🔧 MIUI Settings: the default firmware may have the "Safe Zone" mode (Safe Area) enabled, which adds padding.
  • 🖥️ Incorrect resolution: after updating the system, the display parameters are sometimes reset.
  • 🐞 Firmware bug: in versions MIUI 14–15 there were errors with scaling for individual models (for example, Redmi K50).

Before making changes, check whether the screen behavior is related to a specific application. For example, in YouTube or Netflix black bars may appear due to content restrictions (not all videos support the format 21:9) Try running another application - if the problem persists, go to the system settings.

Method 1: Changing the screen scale in MIUI settings

The easiest method is to use the built-in options MIUIIt is suitable for most models, including Xiaomi 13, Redmi Note 12 and POCO X5:

  1. Open Settings → Screen.
  2. Select item Screen size and text (or Display scale in older versions).
  3. Move the slider Screen size to the right to enlarge scale, or to the left - to reduce.
  4. Click Apply and restart the device.

If the slider is missing, try an alternative path:

  1. Go to Settings → Accessibility → Font and display size.
  2. Activate the option Screen scale and adjust the value manually.

☑️ Check before resizing

Done: 0 / 4
⚠️ Attention: On some devices (for example, POCO M4 Pro), excessive zooming may result in the bottom navigation bar being cut off. If the "Back" or "Home" buttons disappear after the changes, return the slider to its original position.

Method 2: Setting the aspect ratio through "Full screen mode"

For applications that do not automatically support stretching (games, video players), there is a separate setting in MIUI :

  1. Open Settings → Applications → Manage applications.
  2. Select the problematic application (for example, PUBG Mobile or TikTok).
  3. Click Full screen mode (or Display in full screen mode).
  4. Select option Full screen (stretch) or Full screen (crop)if the first option distorts the image.

This option is not available for all applications - its availability depends on the developer's policy. For example, Instagram and WhatsApp usually do not support forced stretching. as it violates their design guidelines.

Xiaomi model Supports full screen mode Limitations
Xiaomi 13 Pro Yes, for most applications Does not work in banking applications (for example, SberBank Online games SberBank Online)
Redmi Note 11 Yes, but with artifacts in games IN Genshin Impact Possible lags when stretching
POCO F4 Yes, with additional gaming options Requires a reboot after changes
Xiaomi Pad 6 Partially (only for optimized applications) Many applications are displayed in mode 4:3 with black bars
💡

If elements disappear in the game after stretching interface (for example, control buttons), try turning on the "Adaptive layout" or "Wide screen support" option in the game settings.

Method 3: Using developer settings

For advanced users, hidden options are available that allow you to force change the screen resolution. Attention: incorrect values can lead to unstable operation system.

How to enable developer mode:

  1. Go to Settings → About phone.
  2. Click on the item 7 times in a row MIUI version (a notification "You have become a developer" will appear).
  3. Go back to the main settings menu and open a new section For developers.

Now you can change the resolution:

  1. In the section For developers find Minimum screen width (or Smallest width).
  2. The default value is usually 360dp or 411dp. Increase it to 480dp–530dp to stretch the interface.
  3. To apply the changes, reboot the device.
adb shell wm size 1080x2400

If you have access to ADB, you can force the resolution through the command above (replace 1080x2400 with one supported by your device). However, this method may cause malfunctions of the camera and some applicationsso use it only if other methods did not help.

What to do if after changing the resolution the screen turns black?

If, after applying the new settings, the screen goes blank or artifacts appear, connect the phone to the PC and run the command adb shell wm size reset. If ADB is not configured, hold the power button for 10-15 seconds to force a reboot (the settings will be reset to factory settings).

Method 4: Correction through graphics settings (for games)

For gamers Xiaomi offers a separate tool - Game Turbo. It allows you to optimize the display in games without changing system parameters:

  1. Open Settings → Applications → Game Turbo.
  2. Select the game in which you want to stretch the screen (for example, Call of Duty: Mobile).
  3. Activate the option Screen resolution and set the value Full HD+ or WQHD+ (if supported).
  4. Enable Full screen mode and select Stretch.

If Game Turbo is not in the settings, it can be installed separately from Mi App Store (not available in all regions). An alternative is to use third-party utilities like GFX Tool, but they require rootrights and can lead to a ban in online games.

⚠️ Attention: In games with a stretched screen, HUD elements (for example, a map in PUBG or control buttons may not be displayed correctly in Free Fire). Before the competition, check the functionality of all functions in training mode.

Method 5: Reset the screen settings to factory settings

If, after experimenting with the scale or resolution, the screen begins to display incorrectly (for example, blur appears or interface elements overlap each other), return the default ones settings:

  1. Go to Settings → System → Reset settings.
  2. Select Reset settings screen (do not confuse with a full data reset!).
  3. Confirm the action and wait for the reboot.

If there is no option to reset the screen, perform a full reset to factory settings, but first save the data:

  • 📁 Backup: Settings → Google → Backup.
  • 📱 Contacts: export via Contacts → Management → Export.
  • 📷 Photo/video: copy to PC or cloud (Google Photo, Mi Cloud).
💡

Resetting the screen settings does not delete user data (photos, messages, applications), but returns the brightness, color temperature and scale to the factory settings.

Solving problems after stretching the screen

Even after successfully stretching the screen, side effects may occur: Here's how to fix them:

Problem Cause Solution
Blurred text Inconsistency between resolution and pixel density Return the scale to Settings → Screen → Text size 100%
Gestures do not work Cropping the bottom navigation bar Enable Settings → Display → Full screen gestures and select "Swipe up"
Artifacts in games Unoptimized graphics for wide screen Disable stretching in Game Turbo or lower the game resolution
Black screen after reboot Incorrect resolution in developer settings Reset via ADB or hold the power button to force reboot

If the problem persists, check for updates MIUI. In some cases, scaling bugs are fixed in new firmware versions. To do this, go to Settings → About phone → System update.

⚠️ Attention: On devices c AMOLED screens (for example, Xiaomi 12T or Redmi K60) long-term use of a non-standard resolution can lead to pixel burnout. This is due to uneven load on the matrix. If you notice residual images (for example, a “shadow” from the navigation bar), return to factory settings. screen.
