How to know exactly which display is installed on your Xiaomi smartphone: from Redmi Note to Mi 14

Have you ever wondered why your Xiaomi Redmi Note 12 screen looks brighter than a friend with the same model? Or why the POCO X5 Pro has more color saturation than the old Mi 10T? It's not just about settings, it's all about the type of display matrix. Smartphone manufacturers (including Xiaomi) often use different panels even within the same model without telling the customer. And the type of screen depends on the quality of the picture, battery life, and even the cost of repairs if damaged.

In this article, you’ll find 5 proven ways to determine exactly which display is installed on your Xiaomi — whether it’s a budget Redmi A2 or the flagship Mi 14 Ultra. We’ll figure out how to distinguish AMOLED from IPS, find hidden data about the manufacturer of the matrix (Samsung, BOE, Tianma), and even find out the resolution of the screen without special applications, and also find out why the same smartphone can be equipped with different displays — and how this affects the user experience.

Why Xiaomi Installs Different Displays in One Smartphone

If you think all Xiaomi Redmi Note 11 Pros have the same screens, you're wrong. The manufacturer often buys panels from multiple vendors — like Samsung Display, BOE or Tianma — and installs them according to the batch. This is called dual-sourcing, and this is why it happens:

• 🔄 Logistics and pricing: If one supplier is having production problems, Xiaomi can quickly switch to another to keep up with smartphone production.
• 💰 Cost reduction: Panels from different manufacturers can vary in price, which allows Xiaomi to save on mass models (for example, Redmi). 10C or POCO M5).
• 📦 Regional features: For some markets (e.g. India or Europe) displays with different specs may be used due to local standards.
• ⚡ Testing new technologies: Xiaomi sometimes implements experimental matrices in limited batches (as it was with the Mi 11 Ultra and its screen from Huaxing Optoelectronics).

But there's a downside: different manufacturers can vary in color reproduction, brightness, and even response time, AMOLED-Samsung panels are generally considered the best in quality, while BOE It can save on lighting, but it can save on budget models like Redmi. 9A) occasionally IPS-low-contrast screens.

⚠️ WARNING: If you buy Xiaomi with your hands, be sure to check the type of display before the deal.Unscrupulous sellers may claim that the smartphone is worth it AMOLED, whereas it's actually cheap. IPS (especially relevant to models POCO X3 or Redmi Note 10).

Method 1: Visual Testing – How to distinguish AMOLED from IPS without software

The quickest way to determine the type of display is through a visual test, which won’t give you the exact name of the array (like the Samsung E4 or BOE NT37701), but will help you know if you have AMOLED or IPS.

1. Look at the color black: Open any dark image or turn on the black wallpaper. AMOLED-The screen will be black (pixels are off) and black IPS It's going to be grayish because of the lighting.
2. Tin the screen: At an angle of 45° ce IPS-And then the color will start to flush out and become paler. AMOLED picture will remain saturated.
3. Check contrast: Turn on high dynamic range (HDR) videos on YouTube. If shadows look deep and light areas don't clog up details, that's an AMOLED sign.

Another life hack: take a magnifying glass and look at the screen at maximum brightness. In IPS, you'll see a grid of pixels with uniform backlight, and in AMOLED, the pixels will kind of burn separately (especially noticeable on a white background), this method works even on the Xiaomi Mi A3 or Redmi 8, where there are no built-in diagnostic tools.

Method 2: Codes for the engineering menu – hidden display data

If the visual test didn't give a definitive answer, you can use hidden service codes, which work on most Xiaomi, Redmi and POCO smartphones (except for some models on MediaTek, where the engineering menu is blocked).

Open the phone app.

Enter the code ##4636##

Go to the tab "Phone Information"

Find the line "Display" or "Panel"

Write down data (e.g., "Samsung ams643je01")

-->

Let’s understand what this data means:

If there is no display data in the engineering menu, try alternative codes:

• #284## - Sensor test (sometimes showing matrix information)
• ##283## - Screen test (can display panel model)
• #6484## - Advanced Display Information (powered by Qualcomm Snapdragon)

⚠️ Warning: Not all service codes are secure! Avoid commands like ##7780## (setting reset) or *2767*3855# (Also, do not change the settings in the engineering menu unless you are sure of their purpose - this can damage the display or a failure in the sensor.

Method 3: Diagnostic applications – AIDA64, CPU-Z and specialized utilities

If the engineering menu doesn't work, there's a special application that's going to come to the rescue, and it's not only going to show you the type of display, it's going to provide you with resolution, pixel density (PPI) Even the screen time (for example, for the AMOLED). Here's the top.-3 utility:

1. AIDA64 (Free version) The way: The system → Display. Here you'll find: 📱 Display model (e.g, BOE NT37701) 🔍 Type of matrix (AMOLED, IPS, TFT) 📏 Permission and PPI (for example, 2400×1080 upon 395 PPI) 🔋 Time of work (relevant to the AMOLED, where the pixels degrade over time)

CPU-Z

Shows basic display information, including resolution and pixel density, but does not always identify the matrix manufacturer.

Display Tester

It allows you to test the screen for broken pixels, gradients and color reproduction. Info displays detailed data about the panel.

On some Xiaomi models (for example, Redmi Note 12 Pro)+ or POCO F5) Applications may show incomplete data due to limitations MIUI. In this case, only a manual analysis of firmware or requesting information through ADB.

💡

If AIDA64 doesn't show a display model, try restarting your smartphone and running the app again. Sometimes the data isn't uploaded the first time.

Method 4: Disassembling firmware through ADB for advanced users

If none of the previous methods worked, the ADB (Android Debug Bridge) is the one that requires you to connect your smartphone to your computer, but it gives you 100% accurate results, including the serial number of the display.

1. Turn on Developer Mode on Xiaomi: Go to Settings → About Phone → MIUI version and tap 7 times on this line.
2. Activate Debugging over USB: Return to Settings → Additional → For Developers and enable the option.
3. Connect your smartphone to your PC and execute the command: adb shell dumpsys display In the output, find the lines mPanelName or mDisplayId - there will be a model of your display.

For example, the POCO X3 Pro with an IPS will last 10-15% longer than the POCO X3 NFC with AMOLED under the same conditions.
