How to increase the screen resolution on Xiaomi phone: all ways + hidden settings MIUI

Have you noticed that your Xiaomi screen is blurry and your images are blurry? Or you want to adjust the maximum image quality for games and videos? In this article, we will discuss all possible ways to increase screen resolution, from basic MIUI settings to hidden features for power users. It is important to understand that the real physical resolution of the screen (for example, 2400×1080 on the Redmi Note 12 Pro+) can not be changed, but you can optimize the display of content, zoom and pixel density (DPI).

Many users confuse screen resolution (the number of physical pixels) with display resolution (how the system scales content). There are several levels of customization available on Xiaomi with MIUI firmware, from simply zooming in settings to manually editing system settings through ADB. We will look at methods for different versions of MIUI (including MIUI 14/15 based on Android 13/14), and also caution against common errors that can lead to interface failures.

If your goal is not just to “increase resolution” but to improve image quality, you may be more likely to be better served by color profile settings (sRGB/DCIP3) or screen refresh rates (60 Hz/90 Hz/120 Hz), which are also discussed in the article.

1. Standard MIUI settings: changing the scale and density of the screen

To start with, the basics are built-in MIUI tools that allow you to customize the display without risk to the system, and these options are available on all Xiaomi models, from the budget Redmi 10A to the flagship Xiaomi 14 Ultra.

To resize the interface:

1. Open the Settings → Screen.
2. Select Text Size and Display (in some versions of MIUI - Screen Size).
3. Move the text size slider to the right to zoom in or to the left to shrink, and that will change the scale of the fonts and some interface elements.
4. Below, find the option Display Size (or Screen Density) – here you can select the preliminary values: Small, Standard, Large, Very Large.

These settings don't change the physical resolution, but they allow you to customize the display to your preferences. For example, choosing a small scale will make the icons and text smaller, which will visually increase the density of information on the screen. However, some models (for example, POCO F5) at extreme values can appear artifacts in games or applications.

2. Hidden developer settings: changing the DPI

To fine-tune the pixel density (DPI), you’ll need to activate Developer Mode, a technique that allows you to set an exact DPI value, which is especially useful for owners of smartphones with large screens (such as the Xiaomi Mix Fold 3), where standard scale settings do not work.

How to turn on the developer mode and change the DPI:

1. Go to Settings. → The phone.
2. Find the MIUI version and tap it 7 times until you become a developer!
3. Return to the main Settings menu and open a new section Additional → For Developers (or System → Advanced Settings → For Developers in MIUI 14+).
4. Find the option Minimum Width (or Least Width). This is the DPI setting. The standard value is 411dp for most smartphones.
5. Change the value to a smaller one (e.g. 380dp for a denser display) or a larger one (e.g. 440dp for an increase in elements).

Not all apps adapt to non-standard DPI values correctly. For example, TikTok or Instagram may have problems with displaying buttons, and in games (for example, Genshin Impact) interface artifacts.

Recommended DPI values for popular Xiaomi models:

Change of permission via ADB (for power users)

If standard methods fail, you can manually set the screen resolution through the Android Debug Bridge (ADB), which requires connecting the phone to your computer and working with the command line. Warning: incorrect commands can cause interface failures or even a device blink!

Step-by-step:

1. Install. ADB-computer-driver.
2. Enable USB debugging on your phone (Settings → Developers → USB debugging).
3. Connect your phone to your PC and open the command prompt (cmd in Windows or Terminal in macOS/Linux).
4. Enter the command to check the connection: Adb devices should appear the name of your device.
5. Find the current screen resolution: adb shell dumpsys display | grep mBaseDisplayInfo In the output, find the line of displayId=0, resolution=1080x2400.
6. Change the resolution (e.g. 1920x1080): adb shell wm size 1920x1080 Attention! Not all resolutions are supported by hardware. If the screen goes out, restart the phone, the settings will reset.

To make the changes last after the reboot, you will need to make edits to the system files, which requires an unlocked bootloader and root rights. For most users, this is risky, so we recommend using ADB only for temporary experiments.

⚠️ Note: Some Xiaomi models (e.g. Redmi) 10C or POCO M5) Modification of the permit through ADB This can cause the sensor to lose calibration, in which case the touchscreen will not work properly until the settings are reset.

4.Optimize resolution for games and videos

If your goal is to improve image quality in games or when watching videos, changing the system resolution may not work.

• 🎮 Permission in games: Many games (e.g., games, PUBG Mobile or Call of Duty: Mobile allows you to manually select the resolution in the graphics settings. The optimal value depends on the phone model: Redmi Note 12 Pro+: 2400×1080 (maximum) POCO X5 Pro: 2400×1080 or 2340×1080 (Depending on the optimization of Xiaomi 13T: 2778×1284 (supportive HDR)
• 🎥 Video resolution: In apps like YouTube or Netflix, the maximum resolution is not only limited to the screen, but also to the screen. DRM-For example, on the Redmi Note 11 Pro video in the 4K It can only be played with Widevine. L1.
• 🔄 Update frequency: On 120Hz phones (e.g, POCO F5 Pro) it is possible to enable adaptive frequency which automatically adjusts to the content, saving battery power.

Important: phones with Snapdragon 7+ Gen 2 processors (such as Redmi K60) may overheat in games when manually selecting QHD+ resolution, in which case it is better to leave automatic mode.

To check the current refresh rate, install the Screen Refresh Rate Tester app from Google Play, which will show the actual frequency, not the one specified in the settings.

5 Problems after the change of permission and their solution

Even with the right settings, there are sometimes failures, and let's look at the typical problems and how to fix them:

If after experimenting with resolution, the phone stopped responding to touch or the screen turned black, perform a hard reset (press Power + Volume up for 10 seconds) that will return the standard settings, but delete all data from the device.

💡

Before changing the resolution or DPI, back up your important data via Settings → Memory → Backup. In the event of a failure, you can quickly restore contacts, messages and photos.

6. Alternative ways to improve screen quality

If the resolution change didn’t produce the desired effect, try other image optimization methods:

• 🌈 Color profile: In Settings → Screen. → Select saturated or sRGB for more realistic color reproduction. AMOLED-screens (such as Xiaomi 13 Pro) are also available for customization DCIP3 color-span.
• 🔦 Adaptive backlighting: Include Adaptive Brightness and Automatic Color Temperature for comfortable perception in different lighting conditions.
• 🛡️ Screen protection: On phones with MIUI 14+ Vision Protection 3.0 is available, which reduces the blue component of light and reduces eye fatigue.
• 🎯 Sensor calibration: If the screen becomes unsensitive to touch after changing the resolution, calibrate through the engineering menu (code ##6484##).

Some models (such as the Xiaomi Mix 4 or Black Shark 5) have additional settings for gamers, such as Game Turbo or MEMC (Motion Smoothing Technology). These features can be included in Settings → Special Features → Game Settings.

7.Screen resolution on Xiaomi foldable phones

Owners of foldable smartphones (Xiaomi Mix Fold 2/3) have unique settings for the internal and external screens, for example, you can set different DPI values or refresh rates for each display.

How to set the resolution for Xiaomi Mix Fold 3:

1. Open the settings → Screen → Screen modes.
2. Choose the External Screen or the Internal Screen.
3. For the internal screen available options: Resolution: 2160×1916 (maximum) Density: 480dp (recommended) Frequency: 120Hz (automatic or fixed)

FHD+ (2520×1080)

HD+ (1800×1080)

The foldable phones also have an App Pair feature available, which allows you to run two apps simultaneously on the internal screen with individual scale settings for each.

💡

On Xiaomi foldable phones, changing the resolution of the internal screen can affect the performance of the stylus. After changing the DPI, it is recommended to recalibrate the pen in the Stylus settings.
