How to change the screen resolution on the Xiaomi phone: all the ways

A smartphone screen is not just a display, it’s a key element of interaction with the device. At Xiaomi (including Redmi and POCO models), screen resolution directly affects image quality, gaming performance, and even battery life, but not everyone knows that this setting can (and sometimes must) be changed manually.

Xiaomi smartphones use native resolution by default, which corresponds to the physical characteristics of the display. However, in some scenarios, its decrease has noticeable advantages: for example, in games like PUBG Mobile or Genshin Impact, a decrease in resolution can increase FPS by 10-15%. On the other hand, it is important to use maximum settings to watch 4K video or work with graphics. In this article, we will discuss all the available ways to change the resolution, from standard MIUI settings to hidden options for power users.

Why change the screen resolution on Xiaomi?

At first glance, it may seem that maximum resolution is always the best choice, but it is not. Here are the key reasons to change this parameter:

• 🎮 Gaming: Decreasing resolution increases FPS It reduces the heat of the processor, especially for low-end models like the Redmi Note 12 or POCO X5.
• 🔋 Battery savings: processing fewer pixels requires less power. 720p instead 1080p autonomy is increased by 8-12%.
• 👓 UI scaling: On larger screens (6.7" and higher), lower resolution makes icons and text larger, which is convenient for users with visual problems.
• 📱 Compatibility: Some older applications only work correctly at certain resolutions (e.g, 480×800 retro-player).

But it's important to understand the downsides of this approach, and when you lower the resolution, you can:

• ⚠️ The clarity of the text and graphics deteriorates (especially noticeable on the AMOLED-screen).
• ⚠️ Some apps (such as Netflix or YouTube) may block playback HD-content if non-standard resolution is detected.
• ⚠️ In games with support for anti-aliasing (smoothing) artifacts may appear.

Method 1: Standard MIUI settings (without root)

The easiest and safest method is to use the built-in MIUI options. It is suitable for most models released after 2019 (including Xiaomi 13, Redmi Note 11, POCO F5, etc.).

1. Open the Settings → Display.
2. Scroll down and select Screen Resolution (on some firmware, the item may be called Screen Size or Scale).
3. In the window that appears, you will see available options. For example, for Xiaomi 12T it is: 2712 × 1220 (maximum recommended) 2340 × 1080 (FHD+) 1600 × 720 (HD+)

Choose the right option and confirm the change. The phone will restart (this is normal).

If the screen resolution item is not in the settings, this may mean:

• 📱 Your model does not support software-level resolution change (relevant for older Redmi devices). 5A).
• 🔄 You have custom firmware installed (for example, LineageOS), where this functionality is disabled.
• 🔒 The manufacturer has blocked the option for a specific regional version (for example, for Chinese firmware). MIUI China).

⚠️ Note: On some models (POCO X3 Pro, Redmi K40) When you change the resolution, you may be able to recalibrate the sensor, and if the screen becomes less responsive to touch, return the settings to the factory settings, or recalibrate to the Settings. → Additionally. → Screen calibration.

Method 2: Using the Developer Mode

For power users who need to fine-tune resolution (e.g., for testing applications or specific tasks), Developer Mode is the method that works on all devices with MIUI 12 and newer, but requires caution.

First, activate the developer mode:

1. Go to Settings. → The phone.
2. Find the MIUI version and tap it 7 times in a row. You will be notified of becoming a developer!
3. Return to the main settings menu and open a new Developer section (usually at the bottom of the list).

Now you can change the permission:

1. In the Developer Settings, find the Minimum Screenwidth (or Smallest Width in English).
2. The default value is 360dp or 411dp (depending on the model). Change it to the desired resolution Value for Smallest width Example models 720p (HD)320dpRedmi 9A, POCO M3 1080p (FHD)360dpXiaomi 11 Lite, Redmi Note 10 1440p (QHD)480dpXiaomi 13 Ultra, Black Shark 5 4K (UHD)530dp+Xiaomi Mix Fold 2
3. Save the changes and restart the phone. The new permission will take effect after the reboot.

This method allows you to set non-standard values, but has limitations:

• 🔍 Only logical resolution (for applications) changes, not physical resolution (for displays), so the clarity of the image will not deteriorate, but the interface will scale.
• 🚫 Some system applications (such as Camera or Gallery) may ignore these settings.
• ⚠️ For example, when the values are excessively high (for example, 600dp on Redmi 9) possible interface artifacts (cut elements, incorrect display of dialog windows).

💡

If, after changing Smallest width, apps start to behave strangely (for example, don’t open to the full screen), try clearing their cache in Settings → Apps → [App Name] → Storage → Clear the cache.

Method 3: Forced change through ADB (for advanced)

If standard methods don’t work or you have to force permission (for example, to test or circumvent application restrictions), you can use ADB (Android Debug Bridge), which requires a computer and basic command line knowledge.

Preparation:

1. Install ADB and Fastboot Tools on PC.
2. Turn on the phone to debug by USB (Settings → For developers → debugging by USB).
3. Connect your phone to your computer through USB-cable (preferably original).

Next, execute the following commands in the terminal (command line):

adb shell


wm size 1080x2340 # example for 1080x2340 resolution (replace with your values)




wm density 440 # pixel density (optional, for zooming)

Decoding of parameters:

• wm size - specifies the physical resolution of the screen. Examples: 720x1600 for Redmi Note 8 1440x3200 for Xiaomi 13 Pro
• Wm density – the density of pixels (DPI). The higher the value, the larger the interface elements. Standard values: 320 for compact screens 440 — for most modern smartphones 560 — for tablets or foldable devices (Xiaomi Mix Fold).

To return the standard settings, do:

adb shell wm size reset


adb shell wm density reset

⚠️ Warning: Incorrectly exposed wm size settings can lead to a broken touchscreen or black screen after rebooting. If this happens, connect your phone to your PC and execute a reset command (see above) or restart in Safe Mode (hold the power button). → long-tail → Safe Mode).

Method 4: Special Applications for Changing the Permit

If you don't want to mess with ADB or the developer settings, you can use third-party utilities. Here are the proven options:

1. Second Screen (Display Changer) 🔹 Allows you to change the resolution and density of pixels without root. 🔹 Works on MIUI 11-14, but requires the debugging on USB. 🔹 Link to Google Play (Free version with restrictions).
2. App Settings (Xposed Module) 🔹 Requires Xposed Framework or LSPosed (for root devices). 🔹 Allows you to set individual permission for each application. 🔹 Supports MIUI 12.5+, It may conflict with some system services.

Display Info

• 🔹 Shows the current permit, DPI and other display parameters.
• 🔹 Useful to check results after changing settings.
• 🔹 Reference (free of charge).

When using third-party applications, consider:

• 🛡️ Security: Download APK Apps from unknown sites may contain malicious code only from official sources (Google Play, APKMirror.
• 🔄 Compatibility: Some utilities do not work on the latest versions MIUI 14 due to Xiaomi's tightening security policy.
• 📱 Performance: Constant resolution change through third-party applications can lead to interface slowdowns.

💡

For most users, standard MIUI settings are enough. Apps and ADB should only be used if you know exactly why you need it and are ready for possible bugs.

How do I get back the standard permit?

If after experimenting with settings, the screen began to display incorrectly (blurred, with artifacts or incomplete display of elements), you can return everything back in several ways:

1. Through MIUI settings: Go to Settings → Display → Screen Resolution. Select the option marked Recommended or Default. Confirm the change and restart the phone.
2. Through Developer Mode: Open Settings → Developer Form. Find the Minimum Screenwidth and set the 411dp value (standard for most Xiaomi).

Through ADB (if the screen does not respond to touch):

adb shell wm size reset


adb shell wm density reset

Reset to factory settings (last resort):

• Go to Settings → About the phone → Reset settings.
• Select Reset all settings (does not delete files, but returns all system settings to default settings).

If after changing the resolution through ADB the phone stopped turning on or the screen became black, but the device reacts to the connection to the PC (vibrates, makes sounds), perform a forced reset via fastboot:

fastboot erase cache


fastboot reboot
