How to find out which screen is installed on Xiaomi: full methods of checking

Owners of Xiaomi smartphones often face a situation when the specifications are stated IPS-matrix, but in fact the device boasts more expensive AMOLED-This is because a manufacturer can use different components from suppliers like Samsung, Tianma or Huaxing in different revisions of the same model. Matrix type identification becomes critical when buying a used device, issuing a warranty or simply to satisfy technical curiosity.

Understanding which display technology your Xiaomi uses directly affects color quality, power consumption and the ability to use the Always-on Display feature. Unlike competitors, the Chinese giant does not always specify a specific panel model in the About Phone settings. However, there are proven ways to look under the hood of the operating system and get accurate data about the iron component of your gadget.

In this article, we'll look at all the current methods, from using hidden engineering menus to installing specialized utilities. You'll learn to distinguish software interpolation from real resolution and understand why neighbors can have different screens on the same Redmi Note. The only way to get a 100% guarantee of compliance with the matrix declared is through engineering code or detailed analysis of system logs.

Why you need to know the type of matrix of your smartphone

Many users ignore this option until they encounter pixel burnout or uneven backlighting. AMOLED-The screens, which are often found in Xiaomi’s flagship and mid-budget lineups (Mi, Xiaomi, Redmi Note Pro series), have a deep black color, as each pixel is individually illuminated. This gives a huge contrast, but carries the risk of Burn-in (burnout of static interface elements) over time.

On the other hand, IPS-The matrices often used in Redmi budget models and POCO, They're not at risk of burnout, and they tend to have a more natural color reproduction when viewed from an angle, but they don't have the perfect black color. Knowing the type of screen is important for setting brightness and color temperature. AMOLED, And there it was. IPS, You are losing functionality that you may have overpaid for.

In addition, when selling a device on the secondary market, the honesty of the seller is highly evaluated.Indicating the exact type of matrix (for example, Samsung E3 AMOLED vs. BOE OLED) can significantly affect the sales speed.

📊 What kind of screen do you expect to see in your budget Redmi?

IPS LCD (standard)

AMOLED (Pleasant Bonus)

I don't know, I don't care.

Just keep it from hitting the eye.

The most reliable and built-in way to test is to use the CIT (Customer Integration Test) mode, which is a section for factory testers that allows you to check the health of all modules, including the display, and to get there, you need to open a standard telephone dialer and enter a special combination of numbers.

Enter the code ##6484## or ##4636##. If the first code didn't work (some versions of MIUI change it), try the second. In the menu that opens, you need to find the item associated with the display. It can be called Display, LCD or Version. When you click on it, you will see technical information, including the vendor ID and matrix type.

⚠️ Warning: When you are in the engineering menu, don't change settings you don't know. Accidental activation of test modes can lead to incorrect color display or sensor calibration, which is difficult to reset without a complete reset.

Inside the test mode, there's often a broken pixel check and light uniformity feature, and it's a great way to measure the quality of the screen before you buy it «LCM Info or Panel Info, you see names like Samsung», «E3», «E4» — it AMOLED. If you have Tianma, Innolux or simply «IPS» — before you is a classic IPS-matrix.

Verification through identification applications

If you don't want to mess with codes or if they're blocked by an operator, third-party apps from Google Play come to the rescue, and they read configuration files and output information in a convenient way. One of the most popular and reliable tools is the Device Info HW app.

Once installed, start the program and go to the Screen tab, where you are interested in the Type and Vendor fields, and the app will clearly indicate OLED, AMOLED or LCD. It will also show real resolution and pixel density, which helps to identify software stretching.

Another powerful tool is AIDA64, which provides you with detailed information on HDR support, color gamut and precise sensor model, which is useful if you plan to use your phone to professionally process photos or view content in high dynamic range.

Why can apps show different data?

Some apps read information from the build.prop file, which can be modified by the manufacturer for marketing purposes. Others, like Device Info HW, poll kernel drivers directly, which gives a more accurate result. The difference in readings is usually related to the depth of access to Android system files.

Analysis of system information through ADB

For advanced users who aren't afraid of the command line, there's a method of connecting to debugging mode, which gives you access to the kernel logs where the most honest information about hardware is hidden. You'll need a computer, a USB cable, and installed ADB drivers.

First, turn on USB Debugging in the Developer menu. Connect your phone to your PC and type a command to get a list of connected devices to make sure you're connected. Then use the command to output logs containing display information.

adb shell dumpsys SurfaceFlinger | grep -i "display"


adb shell getprop | grep -i "panel"

In the output of commands, you'll see rows containing panel identifiers. `ro.vendor.display.lcd` may contain `samsung_e3` or `tianma_nt`. This is the specific model of your screen, and this method eliminates any software cloaking, because the data is taken directly from the proprietis of the system.

💡

If getprop doesn’t produce results, try using adb logcat | grep DSI by running it before restarting your phone. Driver download logs always mention the type of matrix you’ve connected to.

Comparison of characteristics of popular Xiaomi matrices

To interpret the data correctly, it’s useful to know which vendors are most common in Xiaomi devices.The company uses a wide range of panels, and their characteristics can vary significantly even within the same model range.

Below is a table that helps to decipher the found designations and understand what exactly is hidden behind the abbreviations in diagnostic utilities.

Designation/Provider	Type of technology	Characteristics	Where do you meet?
Samsung E3 / E4	AMOLED	High brightness, low power consumption	Xiaomi Mi 10/11, Redmi Note Pro
Tianma	IPS LCD / OLED	Good color reproduction, the risk of uneven lighting	Budget Redmi, POCO M-series
BOE	AMOLED / LCD	Frequent supplier for budget OLED screens	Redmi Note, Xiaomi Lite version
Innolux	IPS LCD	Standard quality, low price	Redmi A/C Budget Segment

Understanding these differences helps to estimate the real cost of a device, such as a smartphone with a Samsung E4 matrix will cost more in the secondary market than the BOE panel, even if the diagonal and resolution are the same, this is due to the resource and quality of color reproduction.

Visual Differences and Practice Tests

If you don't have a computer or software, you can try to identify the type of screen visually. Turn on a pure black image at maximum brightness in a dark room. If the screen glows gray or you see backlights at the edges, it's an LED-lit IPS. If the screen merges with the frame and becomes absolutely black, you have OLED/AMOLED.

Also pay attention to the viewing angles. IPS-matrixes, as a rule, retain color reproduction with a strong deviation, although the brightness may fall. AMOLED-screens can go into greenish or reddish shades when viewed from a sharp angle, which is their technological feature, not a defect.

⚠️ Note: Do not confuse software dimming of the edges of the screen (a function of energy saving or protection against burnout) with the physical properties of the matrix».

Another test is PWM testing, turn on the camera of another phone and point it at Xiaomi's screen at low brightness, and if there are dark bands running across the screen, it's a sign of the low-frequency PWM that many people have. AMOLED-panels. IPS-screens usually flicker less or do not flicker at all, which is more important for people with sensitive eyes.

💡

The black image visual test is the fastest way to distinguish OLED from IPS without installing additional software and connecting to a PC.

Does the type of screen affect autonomy?

Yes, it does. AMOLED-screens consume less power when displaying dark interface themes, as black pixels are simply turned off. IPS-screens are illuminated evenly throughout the area, regardless of the color of the picture, so the dark theme on the screen is not visible. IPS Minimum charge saving.

Can I replace the screen with a better one?

Theoretically, it's possible, but in practice, it's complicated. The plumes and controllers of different arrays (even for one phone model) may differ. Installing a panel from another revision can lead to a broken touchscreen or no image. It's better to look for the original module with the same LCM code.

Is it true that Xiaomi puts different screens in the same model?

It's a standard practice for optimizing supply chains, and Samsung phones can come in one batch, and Tianma phones can come in another batch, and that means a lottery to the user, which is why checking when you buy a used device is so important.
