Where and how to view the screen resolution on Xiaomi phone: a detailed guide

Screen resolution is a key parameter that affects image quality, detail and smartphone comfort. Xiaomi phone owners (including Redmi, POCO and Black Shark sub-brands) often face the need to learn this meaning, whether for customizing applications, checking for compliance with declared characteristics or diagnosing problems. Unfortunately, the manufacturer does not always bring this information to the public eye, and in some models it is even hidden in technical menus.

In this article, we will discuss all the available methods, from standard settings to hidden engineering modes and third-party utilities. You will learn how to check the resolution on Xiaomi with a MIUI shell of any version (including MIUI 14/15), and what to do if the phone displays incorrect values.

1. Standard method: through phone settings

The easiest method is to use the built-in MIUI settings.It is suitable for most models released after 2018 (including Redmi Note 10/11/12, POCO F3/F4/F5, Xiaomi 12/13/14). The interface may vary slightly depending on the firmware version, but the overall logic is maintained.

Follow the path:

1. Open the Settings app** (the gear icon on the desktop).
2. Go to About Phone (sometimes called About Device or Phone Information).
3. Slip on the item All characteristics (or characteristics of the device).
4. Scroll down to the Screen block** – here will be the screen resolution bar with the exact value (e.g. 2400×1080).

💡

If your model does not have the item "All characteristics", try to click several times on the line "Version". MIUI" — This will open a hidden menu with additional data.

⚠️ Note: On certain devices (e.g, POCO X3 Pro or Redmi K50) This section may display the physical resolution of the matrix, rather than the current software resolution, HD+ instead FHD+), It's going to be different than the real thing. To see the actual resolution, go to Settings. → Screen. → Screen resolution.

2. via the screen menu: current and maximum resolution

If you need to know your current operating resolution (rather than the maximum resolution supported by the display), use the screen settings section, which is especially useful for devices with Adaptive Resolution, where the system automatically reduces detail to save battery life.

Instructions:

1. Open "Settings»** → Screen.

⚠️ Attention: On phones with AMOLED-screens (e.g. Xiaomi) 12T Pro or Redmi K60) regime-selecting FHD+ instead QHD+ You may experience a deterioration in color reproduction, and that's because of the subpixel structure of the Diamond Pixel matrix, and to get back the original colors, you can get back the maximum resolution.

3. Engineering menu: hidden display data

For power users and troubleshooting, the method is suitable through the engineering menu (#4636## or MTK Engineer Mode).This display displays real-world display parameters, including physical resolution, pixel density (DPI) and refresh rate. This method works on all Xiaomi models, but requires caution - do not change the settings unless you are sure of their value!

Step-by-step:

1. Open the Phone app** and enter the code: ##4636## Some models (e.g. POCO M4 Pro) may require a code: ##36446337###

Do not change the brightness parameters manually.|Don't press "Factory Reset"|Don't edit the values DPI|Close the menu after viewing.-->

⚠️ Note: On devices with MediaTek processor (e.g. Redmi) 10C or POCO M5) The engineering menu may contain additional tabs LCM Test and TP Test: These display data about the matrix manufacturer (e.g. Samsung) AMOLED or BOE LCD) And this data is useful for verifying the originality of the screen after the replacement.

4. Diagnostic applications: AIDA64, CPU-Z and others

If standard methods don’t work (for example, on custom firmware or after resetting), use third-party utilities that not only show resolution, but also provide complete information about the display: fabrication technology, color depth, HDR10+ support and even the driver model.

Top.-3 apps:

• 📊 AIDA64 — It shows resolution, pixel density (DPI), Physical screen size in inches and matrix technology (AMOLED, IPS, LTPO). Data is taken directly from system files /proc.
• 🔧 CPU-Z — The Device tab contains a Display section with resolution, diagonal and supported refresh rates.
• 🛠️ DevCheck – displays real-time resolution (useful for checking dynamic change when power saving modes are turned on).

Download the applications can be officially:

• 🔗 AIDA64 Google Play
• 🔗 CPU-Z Google Play

5. via ADB: for advanced users

If you need to get screen resolution software (for example, for debugging or automation), use ADB commands. This method is universal and works even on locked devices (when USB debugging is enabled).

Instructions:

1. Connect your phone to your PC and enable USB Debugging in the developer settings (Settings → About Phone → MIUI version – tap 7 times, then go back to Additional → For Developers).
2. Open the command line (or Terminal on Mac/Linux) and type in: adb shell dumpsys display
3. In the output, find the DisplayDeviceInfo block - there will be a line physicalWidth = 1080 physicalHeight = 2400 (values depend on the model).

For quick permission only, use the command:

adb shell wm size

Example of conclusion:

Physical size: 1080x2400

💡

The wm size command shows the current software resolution, not the physical one. If you use zooming (e.g. HD+ on the Redmi Note 11), the value will be below the maximum.

6. Verification through test images

A non-standard, visually visual way to do this is to use a grid-pixel test image to make sure the screen displays the resolution it says it's performing, rather than downgrading, a method that's useful if you suspect that the phone automatically lowers the resolution to save power.

How to check:

1. Download the test image with the grid for your resolution (e.g. here).
2. Open the image on your phone in the gallery or browser.
3. Increase the picture to 100% (no zooming). If the grid lines are flat and not blurred, the screen works in native resolution. If you see artifacts or steps, you turn on low-detail mode.

⚠️ Note: On phones with Pentile-matrixes (for example, Xiaomi Mi 11 Lite), the test grid may look less clear due to the peculiarities of the subpixel structure.

7. Frequent problems and their solutions

Sometimes users are faced with situations where the screen resolution is displayed incorrectly or is not available for change. Let's consider the typical cases and how to fix them.

Problem 1: There is no “Resolution” option in the screen settings.

• 🔹 Reason: On budget models (e.g. Redmi) A1 or POCO C40) permission is fixed and not regulated.

Problem 2: The resolution automatically decreases when the battery is discharged.

• 🔹 Reason: Adaptive Resolution is enabled in the battery settings.
• 🔹 Solution: Open Settings → Battery → Battery modes and disable the Option Optimization of permission.

Problem 3: After the MIUI update, the resolution reset to HD+.

• 🔹 Reason: Reset screen settings when a major update (for example, with a MIUI 13 on MIUI 14).
• 🔹 Solution: Manually return the required permission to Settings → Screen. → Screen resolution.

💡

If the resolution changes, reboot the phone, and the MIUI system sometimes requires a restart to apply the changes correctly.
