How to accurately determine the display model on the Xiaomi smartphone: from Redmi to POCO

Ever wondered why screens on Xiaomi smartphones of the same price range can be so different in image quality? The fact is that even within the same model (for example, the Redmi Note 12 Pro), the manufacturer can install displays from different suppliers — Samsung AMOLED, BOE OLED or IPS from Tianma. The type of matrix depends on color reproduction, brightness, power consumption and even the durability of the screen.

Knowing the exact display model will come in handy in several cases: 1) When buying a used phone to check the originality of the screen. 2) When replacing the display to find the same matrix and avoid problems with color calibration or sensor. 3) For fine-tuning the color profile through Developer Options (if your model supports customization for a specific type of matrix).

In this article, we’ll break down all the working ways to define a display on Xiaomi, including hidden engineering menus and hardware data analysis.

1. Method: through the standard settings of the phone (without root)

The easiest method is to use the built-in MIUI tools. It is suitable for most models released after 2019 (including the Redmi Note 10/11/12 series, POCO F/X, Xiaomi 11/12/13).

1. Open the Settings app (cog icon).

2. Go to About Phone (or Device on new MIUI versions).

3. tap several times on the MIUI version until the notification "You became a developer!" appears.

4. Go back to the main settings menu and open a new Developer section (or Additional → Developer settings).

5. Scroll down to the Equipment block and select Display Information.

Here you will see the main characteristics of the screen: display model (for example, Samsung AMOLED S6E3FA3 or BOE NT37801), Resolution (for example, 2400×1080), pixel density (DPI), refresh rate (for example, 120Hz). Some models (for example, POCO F4 GT) also display the matrix provider - Samsung, BOE, Tianma or Visionox.

Enable the developer mode (stamp 7 times according to MIUI)

Update MIUI to the latest version

Restart the phone and try again

Method: Engineering codes for screen diagnostics

If the standard settings don’t show the display model, you can use hidden engineering codes, which work on most Xiaomi, Redmi and POCO smartphones, but you need to be careful – incorrect input can lead to failures.

Open the Phone app and enter the following combinations:

• 🔢 ##284## - Sensor test (shows the touchscreen manufacturer, but not always the matrix).
• 🔢 ##36446337## - Advanced equipment information (on some models displays the display provider).
• 🔢 ##4636## → tab Phone information → Equipment version (sometimes containing display data).
• 🔢 ##225## - Screen calibration (can show a matrix model at the top of the screen).

For example, on Xiaomi 12 Pro, code ##36446337## outputs the Display Panel line: Samsung AMOLED, and on Redmi Note 11 Pro+, it outputs BOE NT37800. If nothing happens after you enter the code, then your model does not support this method.

AMOLED (Samsung, BOE, Visionox)

IPS LCD (Tianma, JDI)

I don't know, I want to know.

Another option-->

⚠️ Note: Do not enter engineering codes on phones with custom firmware (for example, LineageOS or Pixel Experience). This can cause errors in the operation of the sensor or graphics driver. MIUI risk.

Method: Applications for analysis of equipment

If the first two methods don't work, third-party utilities will come to the rescue, and they read data from hardware sensors and chips, including information about the display. 5 Popular Apps: Here's the Top-3 precisely:

Instructions for using AIDA64 (the most accurate application):

1. Install and open the application.
2. Go to the Display tab.
3. Scroll to the panel model block – the exact display brand will be listed here (e.g. Samsung S6E3HA8 for Xiaomi 13 Ultra).
4. Pay attention to the Manufacturer line – it will show the brand (Samsung, BOE, Tianma, etc.).

In DevCheck, the information you need is in the Hardware → Screen section, which also shows the diagonal size in inches, resolution and pixel density (PPI), which is useful for comparison with the official specifications.

💡

If the application shows an unknown display model (e.g., unknown or generic), try updating the database in the program settings or use an alternative method (see section 4).

Method: Physical examination and comparison with official data

If software methods don't work, you can tell the type of display by its appearance and performance, which is a very careful way to do it, but it works even on phones with a damaged screen or a faulty sensor.

Step 1: Identify the series and model of the phone.

Find the sticker under the lid (on the removable battery or under the tray for the SIM-maps) or check the box. Model is in the format M2xxx (for example, M2102J2SC For the Redmi Note 10 Pro).

Step 2: Compare it to Xiaomi’s display database.

Below is a table of matching models and screen types (relevant for flagships and popular series):

Step 3: Check for visual differences.

• 🔍 AMOLED-screens (Samsung, BOE, Visionox: deep black (pixels off), high contrast, curved edges (on flagships".
• 🔍 IPS-screens (Tianma, JDI): paler colors, gray shade of black, visible decrease in contrast when tilting the phone.
• 🔍 LTPO-displays (on Xiaomi) 13/14 Series: adaptive refresh rate (1–120 Hz), less energy consumption.

⚠️ Note: On some models (e.g. Redmi Note 11 Pro), the manufacturer can install displays from different suppliers even in the same batch. If you buy a used phone, check with the seller the type of matrix - this affects the price (AMOLED more IPS 15-20%).

Method: through ADB-Teams (for advanced users)

If you're familiar with USB debugging, you can get your display data through Android Debug Bridge (ADB), which works on all USB debugging phones, but requires a computer.

Instructions:

1. Enable USB debugging in the developer settings (see section 1).
2. Connect your phone to your PC and install Mi USB Driver drivers.
3. Open the command line (Windows) or terminal (macOS/Linux) and type:

adb shell dumpsys display

In the conclusion, find the DisplayDeviceInfo block. Here will be the lines:

• mDisplayId is the display identifier.
• mManufacturer – Manufacturer (e.g., samsung or boe).
• mModel is a matrix model (e.g., NT37801).

For more detailed information, use the command:

adb shell getprop | grep -i "display"

This will display all the display properties, including supported resolutions and refresh rates.

6. Method: disassembly of the phone (extreme case)

If all the previous methods failed, you can open the phone and look at the markings on the display plume, which is risky — you lose the warranty and you can damage the device, so only use it if:

• 🛠️ You're a skilled repairman.
• 🔧 You have the necessary tools (suction cup, mediator, screwdriver). T3/T4).
• 📱 The phone is no longer warranty or has a damaged screen.

Disassembly instructions:

1. Turn off the phone and remove it. SIM-map.
2. Heat the back cover with a hairdryer (60–70°C) to soften the glue.
3. Carefully apply the cover to the mediator, starting at the bottom edge.
4. Unscrew the screws that hold the metal plate over the battery.
5. Disconnect the display plume (usually located at the top of the board).
6. On the back of the screen, look for a labeled sticker (such as SAMSUNG AMOLED S6E3FC3 or BOE NVT NT37800).

⚠️ Note: On models with adhesive screen mounting (for example, Xiaomi 13 or POCO F4) When disassembling without special equipment, there is a high risk of damage to the touchscreen or matrix.

💡

The most reliable way to determine the display is AIDA64 (software) and physical inspection of the plume (hardware). ADB They may not work on old models or custom firmware.

AMOLED vs IPS Comparison: Which Is Best for Xiaomi?

Knowing your display model can help you optimize your phone’s settings, and here are the key differences between the two main screen types in Xiaomi smartphones:

Recommendations for setting up depending on the type of display:

• 📱 For AMOLED: Turn on a dark theme, turn off animation (saves charge), use adaptive refresh rate.
• 📱 For IPS: Increase brightness to 70-80% for better readability in the sun, calibrate colors manually (in Settings) → Display. → Color mode).
