Screens are a key element of any smartphone that affects user experience, quality of display, and even device autonomy. Xiaomi phone owners (including Redmi, POCO, and Black Shark sub-brands) often face the challenge of knowing the exact characteristics of the display, whether it’s to compare with competitors, check before buying a used device, or adjust optimal display settings.
In this article, we will discuss 7 proven ways to find out how to screen resolution, matrix type (AMOLED, IPS, LTPO), refresh rate, pixel density (PPI) and other key parameters on any Xiaomi device. The methods are suitable for both new flagships (Xiaomi 14 Ultra, Redmi K70 Pro) and budget models (POCO M6, Redmi Note 12).
1. Check the screen characteristics through the settings Xiaomi
The quickest way is to use the built-in MIUI tools. The manufacturer hides some of the technical data, but the basic parameters are available without third-party applications.
Go to the menu: Settings → About the phone → All the characteristics
Here you will find:
- 📱 Screen resolution (e.g., screen resolution, 2400 × 1080 Xiaomi 13T).
- 🔄 Update frequency (standard and maximum if supported by AdaptiveSync).
- 🎨 Color depth (usually 16.7 million shades for modern models).
However, there is no information on the type of matrix (AMOLED/IPS) and the actual brightness - this data will have to be searched for in other ways. Also note: in some firmware, the item "All characteristics" may be called "Device specifications" or hidden behind the button "Additional information".
💡
If your model does not have the item "All characteristics", try to enter in the search for settings the request "screen resolution" - the system will redirect you to the desired section.
2.Use of the engineering menu (for advanced users)
Engineering menu (##4636## or ##36446337##) This allows you to get advanced data about the display, but it requires caution - wrong actions can disrupt the device. Xiaomi/Redmi/POCO).
Instructions:
- Open the Phone app and enter the combination ##4636##.
- Select Hardware Testing (Equipment Testing).
- Click Display – it will be displayed here: 🔢 Physical authorization (e.g, 1080p or 1440p). 🔄 Current refresh rate (relevant for dynamic screens). 📊 Color profile (sRGB, DCI-P3 etc.).
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, a forced change in the refresh rate can lead to artifacts or overheating of the screen.
3. Third-party screen analysis applications
If built-in tools aren't enough, use specialized utilities that not only show specifications, but also test the screen for broken pixels, color reproduction and uniformity of the backlight.
Top.-3 apps:
- 📱 DevCheck – displays matrix type, resolution, PPI and supported standards HDR.
- 🔍 Screen Test – Checks the screen for defects (dead pixels, gradients) and shows the real refresh rate.
- 🎨 Display Tester – analyzes color coverage, contrast and brightness (requires calibration).
Example of data from DevCheck for Redmi Note 12 Pro+:
| Parameter | Meaning |
|---|---|
| Type of matrix | AMOLED, 120Hz |
| Permission | 2400 × 1080 (FHD+) |
| PPI | 395 |
| Color coverage | 100% DCI-P3 |
| Max. brightness. | 1,200 nits (peak) |
🔹 Important: Some applications (e.g, CPU-Z) It shows inaccurate data about the type of matrix. For Xiaomi, it is better to use DevCheck or AIDA64 — They read information directly from the system.
4. How to determine the type of matrix (AMOLED vs IPS)
The manufacturer rarely specifies the type of matrix in the settings, but it can be determined by indirect signs or by using tests.
Recognition methods:
- 🔦 Black test: Set up black wallpaper and look at the screen from an angle. If the pixels are completely turned off (black looks "deep"), it's AMOLED. Nana IPS blackish.
- 🔄 Update frequency: If the screen supports 120Hz or higher, it is likely to be AMOLED (The exception is the Redmi Note 11 Pro.+ s IPS 120 Hz).
- 💡 Backlight: On AMOLED at maximum brightness there is no "glow" at the edges (characteristically for IPS).
For the precise definition:
- Install the AndroSensor app.
- Go to the Display tab.
- Look at the Panel Type bar, and it will be AMOLED, LTPO, or LCD (IPS).
⚠️ Note: Some Xiaomi budget models (e.g. Redmi) 10A) stand TN-matrix IPS. It is easily recognized by poor viewing angles and pale colors.
5. Performance verification through ADB (for technicians)
If you want the most accurate data (for example, to compare with official specifications or after-repair diagnostics), use ADB (Android Debug Bridge).
Instructions:
- Enable Developer Mode on Xiaomi: Go to Settings → About Phone. Click 7 times on MIUI Version. Return to Settings → Additional → For Developers and activate Debugging over USB.
adb shell dumpsys displayDisplayDeviceInfo
- 📏 Physical screen size in inches.
- 🔢 Real resolution (may differ from the stated one due to software optimization).
- 🔄 Supported frequencies (e.g. 60, 90, 120 Hz).
Example of output for POCO F5 Pro:
DisplayDeviceInfo{
...
flat panel dimensions: 161.2mm x 73.7mm (6.67")
resolution: 3200 x 1440
refresh rates: [60.0, 120.0]
...
}🔹 Key conclusion: ADB It shows real-world characteristics that may differ from the official ones. 12T the settings indicate the permission 2712 × 1220, through ADB It is evident that the physical — 2400 × 1080 programmatically scaled.

6. How to find out the characteristics of the screen on the Xiaomi model
If you haven’t bought a phone yet or want to compare several models, use official and unofficial sources.
Where to look:
- 🌐 Xiaomi official website: Specifications for each model (e.g. mi.com) but often lacks data on the type of matrix or the actual brightness.
🔍 Tip: To check used phones, use the service IMEI.info - it will show the original characteristics by serial number. This will help to identify the change of screen (for example, if instead of using the serial number). AMOLED cheaply-fit IPS).
⚠️ Note: Xiaomi is often found on the market with “cheat” screens – for example, Redmi Note 11 Pro with a matrix IPS instead AMOLED. Check the specifications immediately after purchase!
7. Screen diagnosis after repair or fall
If the phone fell or was repaired, the screen characteristics could change, for example, instead of the original 120Hz AMOLED, a 60Hz IPS could be installed.
Signs of a non-original screen:
- 🎨 The colors became paler or appeared a yellowish tint.
- 🔄 The frequency of update is fixed on 60 Hz (even if the settings are selected) 90/120 Hz).
- 💡 Brightness below declared (for example, instead of 1000 nits, a maximum of 400).
- 🔍 Artifacts are visible when scrolling (blurring, "shadow" behind objects).
For a thorough check:
- Install the Screen Test app and run the Dead Pixels test.
- Check the uniformity of the backlight on a gray background (on non-original matrices, "clouds" are often visible).
- Compare the actual update rate with the one announced via DevCheck.
🔹 Important: If the screen is repaired IPS instead AMOLED, It's not always a fake, some service centers install service matrices with different characteristics.
💡
Even if the screen looks normal, the specs may have changed, and always check the settings after repair, which affects the autonomy and comfort of use.
