Why do you need to know Xiaomi’s screen resolution?
Screen resolution is the number of pixels horizontally and vertically, which directly affects the clarity of the image. POCO This parameter varies from 720×1600 budgetary models to 1440×3200 Knowing the exact resolution will help you set up applications, select wallpapers, assess compatibility with the VR-Selecting or selecting protective glass.
For example, if you're installing a high-resolution game, it's important to know if your Xiaomi can display graphics at its best. Or if you're buying a camera-cut case, manufacturers often specify model and resolution compatibility. Even for basic color calibration in screen settings, it's helpful to know the original matrix settings.
In this article, we will discuss all the current methods of checking resolution, from standard MIUI tools to third-party applications and analysis of technical specifications, and pay special attention to the nuances for models with dynamic resolution (for example, Xiaomi 13 Ultra or POCO F5 Pro), where the system automatically adjusts the parameters for the content.
Method 1: via MIUI settings (fastest)
The easiest method is to use the built-in MIUI shell tools, which works on all Xiaomi smartphones, regardless of the model and firmware version, and you do not need to install additional programs or connect to the Internet.
Instructions:
- Open the Settings app (the gear icon on the home screen).
- Go to About Phone (usually at the bottom of the list).
- Tap on All Device Specifications or Specifications (the name may vary depending on the MIUI version).
- Find the Display block – there will be a screen resolution bar with exact numbers (for example, 1080 × 2400).
On some models (e.g. Xiaomi 12T or Redmi Note 11 Pro+), the path may be slightly different: Settings → Display → Additional settings → Screen resolution.
Find the "About the Phone" section"|Open "All characteristics"|Flick to the "Display" block"|Remember or photograph the meaning of the permission-->
⚠️ Note: On devices with automatic zoom function (e.g, POCO F4 GT) This menu can display effective resolution, not physical resolution. To see the real parameters of the matrix, use method 3 or 4.
Method 2: through the Engineering Menu (for advanced)
If the standard settings do not show resolution or you want to get advanced information about the display (for example, pixel density, matrix type), you can use the engineering menu. This method requires caution, since incorrect actions can disrupt the system.
Step-by-step:
- Open the Phone app and enter the combination: ##4636##.
- In the menu that appears, select Phone Information (or Testing on some firmware).
- Scroll down to the Display block - there will be options: 📏 Resolution – Physical permission (e.g., resolution, 1080x2340). 🔍 Density – The density of pixels (DPI). 🎨 Color Mode – Current Color Profile.
On some models (e.g. Xiaomi Mi 11), the engineering menu may be blocked, in which case try the alternative code: ##2486## or ##284## (to test the sensor).
What to do if the engineering menu is not opened?
⚠️ Warning: Do not change the settings in the engineering menu unless you are sure of their purpose! For example, changing the Density value can cause the interface to crash, and incorrect sensor calibration can lead to broken touches.
Method 3: Using AIDA64 (maximum data)
AIDA64 (formerly known as CPU-Z) provides the most detailed information about a smartphone’s hardware, including screen resolution, matrix type, supported refresh rates, and even the display manufacturer.This is the only way to find out the physical resolution on dynamically tuned devices (such as the Xiaomi 13 Pro or Redmi K60 Pro).
How to use:
- Download AIDA64 from Google Play (the free version is quite functional).
- Launch the application and go to the Display section (Device tab).
- Pay attention to the lines: 📺 Resolution – Current Active Authorization. 🔧 Physical Resolution: Physical resolution of the matrix (may differ from active resolution). 🔄 Refresh Rate – The refresh rate of the screen (e.g. 120 Hz). 🎨 Pixel Density – pixel density (ppi).
The advantage of AIDA64 is that it shows real-world features, not those that the system emulates. For example, on the 1080p/1440p POCO X5 Pro, the app will display both values, whereas the MIUI settings will only show the current one.
💡
In AIDA64, you can save your performance report to a.txt or.html file. This is convenient if you need to provide phone details for repair or sale. Click on the floppy disk icon in the upper right corner and select the format.
| Parameter | What does it mean? | Example of meaning |
|---|---|---|
| Resolution | Current Active Authorization (may change) | 1080 × 2400 |
| Physical Resolution | Physical resolution of the matrix (not changed) | 1440 × 3200 |
| Refresh Rate | Screen refresh rate | 90 Hz or 120 Hz |
| Pixel Density | Pixel density (ppi) | 395 or 446 |
| Display Technology | Type of matrix (AMOLED, IPS, etc.) | AMOLED, 10-bit |
Method 4: via the Screen Test application (for quality check)
If you need to not only get the resolution, but also check the display quality (for example, for broken pixels or uneven backlighting), use the Screen Test application.
How it works:
- Install and open the application.
- Go to the Info tab (or Information).
- The Display block will specify the resolution, pixel density, and color spaces supported (e.g., sRGB or DCIP3).
- To check the quality of the matrix, use tests for broken pixels, gradients and color transitions (Tests tab).
- 📊 GSMArena database: gsmarena.com – type the model into search and scroll to the Display block.
- 🛒 Product card in stores: On AliExpress or Amazon, the specifications always indicate the permission.
It is better to check the resolution on such devices through AIDA64, since only the active display can be displayed in the settings.
