How to find out the screen resolution on Xiaomi phone: all the ways for Redmi, POCO and Mi

Have you ever wondered what the actual screen resolution of your Xiaomi, Redmi or POCO is? This information might be needed to customize games, select wallpapers, check for compliance with stated characteristics or even when selling a device. Manufacturers often specify the resolution in technical specifications, but what if the documentation is lost and the inscriptions on the box are erased?

In this article, we’ll look at all the possible ways to determine the screen resolution on Xiaomi smartphones, from standard MIUI settings to hidden engineering menus and third-party applications. You’ll learn how physical resolution differs from software resolution, why some models display an incorrect value, and what to do if the phone does not recognize native resolution after firmware.

We will pay special attention to the nuances for different lines: budget Redmi Note with FHD+, Xiaomi 13 with flagship 2K-displays and gaming POCO F with high refresh rate. We'll also look at how resolution relates to pixel density (PPI) Why can you manually change this value on some devices.

1. Method: through standard MIUI settings

The easiest method is to use the built-in MIUI shell tools, which works on all modern Xiaomi smartphones, including the 2020-2026 models, and does not require the installation of additional programs.

Instructions:

• 📱 Open the Settings app** (the gear icon on the home screen).
• 🔍 Scroll down and select About Phone (on some firmware – About Device).
• 📊 Tap on item All characteristics (or characteristics of the device).
• 🖥️ Find the line “Screen resolution”** – the current value will be indicated here (for example, 2400 × 1080).

Important! Some devices (like the POCO X3 Pro) display software resolution in this menu, not physical resolution. If you scaled the interface in the display settings, the value may differ from the factory one.

⚠️ Note: On smartphones with MIUI 14+ If you don't have all the features, try an alternative route: Settings → System system → The phone. → Version. MIUI (Tap 5 times according to the firmware version to open the hidden menu).

Path: Settings → The phone. → All characteristics|The "Screen Resolution" string should contain two numbers (e.g, 2340×1080)|If there is no data, update it. MIUI last-minute|Compare the value with the official model specifications on Xiaomi’s website-->

2. Method: through the engineering menu (for advanced users)

If standard settings don’t show resolution, or you suspect that the display isn’t working in its native resolution (for example, after firmware), you can use a hidden engineering menu.This method is suitable for all Xiaomi models, but requires caution – wrong actions can disrupt the device.

How to open the engineering menu:

1. Open the Phone app** and enter the combination: ##4636###.

On some devices (e.g. Xiaomi 12T), the engineering menu may not show resolution, in which case use an alternative code:

##225##

It will open the Calibration menu**, where the current resolution and pixel density (DPI) will be displayed at the top of the screen.

⚠️ Warning: Do not change the parameters in the engineering menu unless you are sure of their purpose! DPI It can cause the interface to crash and you will have to reset to factory settings.

3. Method: Using apps from Google Play

If you need not only resolution, but also additional data about the display (e.g. PPI, matrix type, HDR support), it is more convenient to use specialized applications. We tested 5 popular utilities and selected the most accurate ones.

How to use DevCheck (Step-by-step):

• 📥 Install the application and open it.
• 📺 Go to the "Hardware" tab»** → Display.

💡

If the app shows a resolution of 720×1280, but you are sure that your model has FHD+, try turning off the text zoom function in the MIUI display settings.

Method: through ADB-teams (for developers)

This method is suitable for users who have experience with Android Debug Bridge (ADB) and allows you to get the most accurate data directly from the Android system, including supported resolutions and current display settings.

What you need:

• 🖥️ A computer with installed Xiaomi drivers and ADB.
• 📱 Included debugging by USB on the phone (Settings) → The phone. → Version. MIUI — Slip 7 times; then Settings → Additionally. → For developers → Debugging by USB).
• 🔌 USB-cable (preferably original).

Commands to verify the permit:

adb shell dumpsys display


adb shell wm size

In the first command output, look for the mBaseDisplayInfo string, which will indicate the physical resolution (e.g., 1080x2400). The second command will show the current software resolution, which may vary.

⚠️ Note: If you see override in the output next to the resolution, it means that the system is not using a native value. This may be due to custom firmware or manual change. DPI.

5. Method: through the manufacturer's website (to check factory characteristics)

If you need to know the factory resolution (for example, to compare with the current one), the most reliable source is the official Xiaomi website, which is especially useful if you are buying a used device and want to make sure that the seller does not hide the defects of the display.

How to find the characteristics:

1. Go to mi.com (or regional domain, such as mi.com/ru).
2. In the search box, type in your device model (e.g. Redmi Note 12 Pro+ 5G).
3. On the product page, open the "Specifications" tab** (or Characteristics).

Examples for Xiaomi 13 Ultra:

• 🎨 Type of matrix: AMOLED, Support for Dolby Vision.

If your device is not on the site (for example, this is a limited version for China), try searching on resources like GSMArena or PhoneArena. They collect data from all regions.

💡

Compare the data from the official website with the one your phone shows. If the difference is more than 20% (for example, instead of 1080p 720p is displayed), this may indicate a software failure or replacement of the screen with a non-original one.

Frequent problems and their solutions

Sometimes users find that the screen resolution is not correctly determined or the phone is not in its native resolution, and let's look at typical situations and how to fix them.
