Sprawling screen in PUBG on Xiaomi: how to turn on and configure correctly

PUBG Mobile players on Xiaomi smartphones (including the Redmi and POCO lines) often face the problem of incorrect display of the game interface - black bars on the sides of the screen or cropped HUD elements. stretch display solves this problem, but its setting on devices with MIUI has nuances. Unlike the standard mode, stretching the picture gives a wide view (up to 18:9 or 19.5:9), which is critical for competition, but can affect performance.

It is important to understand that stretching methods depend on the version of MIUI, smartphone model and version of PUBG Mobile (or Battlegrounds Mobile India for Indian users). Some methods require unlocking the bootloader or root rights, which will void the warranty. In this article, we will look at legal methods without root rights, relevant for MIUI 14/15 (Android 13/14), as well as alternative solutions for older devices.

Why are there black stripes on Xiaomi in PUBG?

Black bars are caused by a discrepancy between the sides of the screen and the permissions supported by the game engine.

• 📱 Hardware restrictions: PUBG Mobile is optimized for standard resolutions (16:9, 18:9), and many Xiaomi (for example, Redmi Note 12 Pro)+ or POCO F5) Have 20:9 or 19.5:9 screens.
• 🎮 Game settings: By default, the game chooses a "safe" resolution to avoid artifacts on non-standard displays.
• 🔧 Limitations MIUI: Firmware blocks forced stretching for games due to the risk of overheating or falling FPS.

As a result, the player loses up to 10-15% of the field of view, which is especially noticeable in close combat or when watching through the sight. For example, on the Xiaomi 13 Ultra with a resolution of 3200×1440, the game can only use 2400×1080, cutting edges.

Official ways to stretch the screen without root

Try the methods that don’t require any changes to the system first. They work on most devices with MIUI 12+ and PUBG Mobile version 2.6+. Importantly, before setting up, disable the auto-update game on Google Play to avoid resetting the settings.

Method 1: Graphics settings in the game itself

The easiest way is to use the built-in PUBG Mobile options:

1. Start the game and go to Settings → Graphics.
2. Find the screen style option (or Display Mode in English).
3. Select Stretching instead of Standard or Auto.
4. Confirm the changes and restart the match.

⚠️ Note: Some devices (e.g. Redmi Note 10 Pro) may not have this option.

Method 2: Forced stretching through the "Developers Mode"

If the game does not have a stretch option, activate the hidden MIUI settings:

Activate Developer Mode (click 7 times on "Version") MIUI" on the telephone")

Enable debugging over USB (in "Additional settings → For developers")

Disable MIUI Optimization in the same settings (only for MIUI 12.5+)

Reset the device-->

1. Activate Developer Mode: Go to Settings → About Phone → MIUI Version and click on it 7 times.
2. Return to Settings → Additional settings → For developers.
3. Find the option Force Full Screen Display (Forced Change)
4. Select PUBG Mobile from the list of apps and set 18:9 or 19.5:9 (depending on the model).
5. Save the settings and restart the game.

🔹 Note: On POCO F4 GT Black Shark 5 can cause artifacts in the game menu, but in the match the stretch will work correctly.

Screen stretching through ADB (no root)

If previous methods have failed, use Android Debug Bridge (ADB), which requires a PC connection but does not violate the warranty.

• 💻 Computer with Windows/macOS/Linux and installed Xiaomi drivers.
• 📋 Cable USB (preferably original).
• 🔧 Utility. ADB Tools (download from the official website).

Instructions:

1. Connect your smartphone to your PC and allow debugging over USB (a request will appear on the phone screen).
2. Open the command prompt (or Terminal on macOS/Linux) in the adb.exe folder.
3. Enter the command to check the connection: Adb devices must appear serial number of your device.
4. Follow the command for forced stretching: adb shell wm size 1080x2400 Replace 1080x2400 with your screen resolution (e.g. 1080x2340 for Redmi Note 11 Pro+).
5. Restart PUBG Mobile.

⚠️ Attention: Once the phone is restarted, the stretch will reset. To make it permanent, create a tasker script or use the SetEdit app (requires root).

💡

After the team ADB The game starts to lag, try to reduce the permission to 10-15% (for example, 1080x2400 before 1080x2160). It'll reduce the load on you. GPU.

Comparison of stretching methods: pros and cons

The choice of method depends on the smartphone model, the version of MIUI and your skills.

For most users, the second method (through developer mode) is optimal, since it does not require a PC and gives a stable result, and the ADB method is suitable for experienced players who are willing to sacrifice convenience for the sake of maximum field of view.

💡

On the POCO X3 Pro and Redmi K40, stretching through ADB can lead to blurring of text in the game menu, in which case return the standard resolution command adb shell wm size reset.

4. Run the game from Second Space - stretch settings will apply.

🔹 Plus, it doesn't require root, it doesn't affect the main profile, and it doesn't affect the main profile.

Optimal settings for maximum FPS

A stretched screen can reduce performance. To minimize FPS losses, follow these guidelines:

• 🎯 Resolution: For Snapdragon 865/870/888 (for example, POCO F3 or Mi 11) optimally 1080x2400 upon 60 Hz or 1080x2280 upon 90/120 Hz.
