How to watch the screen resolution on Xiaomi: all the ways for smartphones and tablets

Screen resolution is a key parameter that affects image quality, text clarity and smartphone comfort. On Xiaomi devices (including Redmi and POCO sub-brands), this characteristic can differ even in models of the same line: for example, the Redmi Note 12 Pro has 1080×2400, and the basic version of the Redmi Note 12 is 1080×2460. Knowing the exact resolution will help when choosing wallpaper, scaling adjustments or diagnosing display problems.

In this article, we’ll look at 5 proven ways to find out how to display Xiaomi’s screen resolution, from standard settings to hidden engineering menus. You can check the settings on both new flagships (Xiaomi 14 Ultra, POCO F6 Pro) and budget models (Redmi A2, POCO M6). And if your device doesn’t display information through the menu, we’ll show alternative methods using third-party apps.

Special attention will be paid to the hidden code ##4636## to call the service menu Android, which works on most Xiaomi devices regardless of the version of MIUI. This method is often overlooked, although it gives the most accurate data about the display, including pixel density (DPI) and physical screen size.

1. Standard method: through Xiaomi settings

The easiest method is to use the built-in MIUI settings. It is suitable for all modern Xiaomi, Redmi and POCO smartphones running MIUI 12 and later. The main advantage is that it does not require the installation of additional applications or administrator rights.

Instructions:

• 📱 Open the Settings app** (the gear icon on the home screen).
• 🔍 Scroll down and select About Phone (on some models – About Device).
• 📊 Tap on All Features (or Specifications in Older Versions) MIUI).
• 🖥️ Find the Display block** – here will be the resolution in width format × height (e.g., height, 2400 × 1080).

On some devices (such as the POCO X5 Pro), the path may be slightly different:

Settings → System → About phone → Equipment characteristics → Display

⚠️ Note: On smartphones with MIUI For the global market (e.g. Xiaomi) 13T For Europe, all features can be called Hardware info or Device specs. If you don't find the right item, try changing the system language to English - sometimes this makes navigation easier.

Open "Settings"

Find the About Phone section.

Go to "All Characteristics"

Flick to Display block.

2. via the Android service menu (#4636##)

The Android Hidden Engineering Menu provides detailed information about all components of the device, including the display, which works on 90% of Xiaomi devices, except for some models with heavily modified firmware (such as Black Shark).

How to open it:

1. Enter the combination: ##4636## (no spaces).

• 📱 Physical screen size in inches (e.g. 6.67")

This method provides the most accurate data, since the information is read directly from the display drivers. However, on some devices (for example, Xiaomi Pad 6), the menu can be blocked by the manufacturer, in which case use alternative methods.

3.Use of the Application "Technical Information" (MIUI)

Xiaomi has built-in diagnostics app Hardware Info, which is pre-installed on most smartphones with MIUI 13/14 and contains a section with detailed display characteristics.

How to find it:

• 🔍 Open a search by device (swipe down on the home screen) and enter Technical Information.
• 📱 Or go along the way: Settings → Additionally. → Technical information
• 🖥️ In the menu that opens, select the Display tab - here it will be indicated:

The advantage of this method is that you don’t have to enter codes or install third-party programs, but on some budget models (for example, Redmi 10A), the application may not be available.

Annex “Technical information”

Third-party programs (AIDA64, CPU-Z)

I don't know, I never checked.-->

4 Third-party applications: AIDA64, CPU-Z, DevCheck

If the built-in methods don’t work (for example, on custom firmware or old devices), you can use specialized utilities that will not only show the screen resolution, but also provide full information about the hardware of the smartphone.

Top.-3 check-in:

• 📊 AIDA64 — displays, DPI, display-technology (AMOLED/IPS) and even a screen model (such as Samsung) E4). Link to Google Play.
• 🔧 CPU-Z — The Device tab contains a "Display" block** with resolution and pixel density.

Example of data from AIDA64 for Xiaomi 13 Pro:

Display:




- Resolution: 3200 × 1440




- Density: 522 dpi




- Size: 6.73 inches




- Technology: AMOLED, 120 Hz, HDR10+




- Manufacturer: Samsung (E6 panel)

⚠️ Note: On devices with root rights (root) applications like AIDA64 They can show advanced information, including screen serial number and color calibration data, but they don't require permission from a superuser to simply verify the permission.

💡

If you check the device’s specs frequently, add the DevCheck widget to the home screen, which displays key settings (including screen resolution) without having to open the app.

5. Through ADB-Teams (for advanced users)

If you're familiar with ADB debugging, you can get your display data directly from the system, which is useful for devices with damaged screens (for example, if the image is partially displayed) or custom firmware, where standard methods don't work.

Instructions:

1. Enable “USB Debugging”** in the developer settings (Settings → About Phone → MIUI version – tap 7 times, then go back to Additional → For Developers).

Alternative command to obtain permission only:

adb shell wm size

Example of conclusion:

Physical size: 1080x2400

This method is 100% accurate, as the data is read directly from the display driver, but it requires ADB skills and is only suitable for advanced users.

💡

ADB-commands allow you to get information about resolution even on devices with a broken screen or a broken touch screen, if USB-debugging was included in advance.

6. Check through Fastboot mode (for non-functioning devices)

If the Xiaomi smartphone does not turn on or the screen does not display the image, but the device reacts to the connection to the PC, you can try to get data about the display through the Fastboot mode.

How to check:

1. Turn off the smartphone (if it is on, hold the power button for 10+ seconds).
2. Press the Power Button + Volume Down before the Fastboot logo appears (a robot labeled FASTBOOT).
3. Connect the device to the PC and open the command line.
4. Enter the command: fastboot getvar all
5. In the output, find the parameters associated with the display (for example, panel: or lcd:). On some devices, the resolution may be specified in the bar ro.sf.lcd_density (pixel density).

Example of output for POCO X3 Pro:

(bootloader) panel:otm1911b_fhd_plus_video




(bootloader) ro.sf.lcd_density:420

⚠️ Note: Not all Xiaomi devices display screen resolution information in Fastboot mode. If there is no display data in the command output, try an alternative method using the screen resolution. EDL-Mode (requires an authorized Mi Unlock account).

Comparison of methods: which one to choose?

Depending on the situation, the appropriate method may differ, and below is a comparative table with the pros and cons of each option:

For most users, a combination of built-in settings and a service menu is the best option. If you want the most complete data (for example, to compare with the official specifications before buying a used device), use AIDA64 or DevCheck.
