How to find out the type of display Xiaomi: all ways to check

Modern Xiaomi, Redmi and POCO smartphones come with screens of a variety of technologies, from budget IPS to flagship AMOLED panels. Users often wonder how to find out the type of Xiaomi display to check for compliance with the declared characteristics or choose the right color calibration strategy, this is especially true when buying a device from hand or when you suspect a replacement screen at a service center.

Manufacturers rarely put this information in the standard settings menu, hiding it in deep system logs or engineering sections. However, there are proven methods to access technical data about the matrix without obtaining root rights. In this article, we will examine all the available methods, from simple visual analysis to the use of specialized software.

Understanding what type of matrix is installed in your device is critical to brightness and color performance. For example, AMOLED screens require a different approach to energy saving than traditional LCD panels, which are often labeled IPS. Let's look at methods for determining in increasing order of complexity.

Visual Diagnostics and Black Checkup

The fastest way to get a first impression of the type of matrix is through a visual black display test. You don't need any tools, you just need to turn on an image with a completely black background. If the screen of the device looks off in total darkness, merging with the frame of the case, you have an AMOLED or OLED panel.

In these displays, each pixel is individually illuminated, and to display black, they simply turn off. This provides endless contrast and battery savings when using dark themes. Unlike them, IPS (LCD) screens have a constant backlight of the entire canvas, so black will always look like a dark gray glow.

⚠️ Note: Do not test for maximum brightness in total darkness for a long time, this can cause temporary eye discomfort and will not give an objective picture due to the adaptation of the pupils.

However, the visual method is not always 100% accurate, as modern methods are not always accurate. IPS-The panels can be very deep black due to local dimming or quality filters, and there are hybrid technologies such as Mini-LED that can mimic behavior. OLED. Therefore, it is better to use software tools to obtain accurate data.

💡

When buying a used smartphone, be sure to check the viewing angles: on IPS, colors can invert with a strong tilt, while AMOLED retains color reproduction.

Using the Xiaomi Engineering Menu

MIUI and HyperOS have a powerful diagnostic menu hidden in their firmware, accessible through a special code. This method allows you to know the type of Xiaomi display without installing third-party software. To enter the menu, you need to open a standard phone dialer and enter the combination ##6484##. If the code does not work, try ##4636#, although it is more often used to test the network.

Once you enter the code, you will open the CIT (Customer Integration Test) interface, and you will need to find the section associated with the screen, usually called "Display," "Screen" or "Version," and you click on it and you will be taken to the testing menu, which often displays the technical name of the matrix or component supplier. Look for lines containing manufacturer acronyms such as Samsung, BOE, Tianma or Huaxing.

The interface of the engineering menu may vary depending on the Android version and shell. In some cases, the matrix type information may be encrypted as the driver version code, such as a line beginning on the device "mdss_dsi_", It may include a reference to the technology of the connection and the type of panel. DSI (Display Serial Interface, which is the standard for modern mobile screens, does not indicate the technology of glow directly.

Analysis through diagnostic applications

If the built-in tools do not give a clear answer, specialized applications from the Google Play Store come to the rescue. The most popular and reliable tool is Device Info HW. This application is able to read information directly from the device drivers, providing data about the model of the processor, sensors and, importantly, the display.

After installing and running the app, go to the Screen tab, where you will see detailed information: resolution, pixel density (DPI), refresh rate and, most importantly, matrix type. The program often directly indicates LCD, AMOLED or OLED. You can also find out the color bits (8-bit, 10-bit) and HDR10+ support.

• 📱 Device Info HW — shows the exact model of the touch controller and the type of matrix.
• 🔍 AIDA64 — universal tool that displays the type of display in the "Monitore" section".
• 🛠 CPU-Z — Provides basic information about resolution and physical size, indirectly indicating the type.
• 📊 TestM – a comprehensive tester, which in the screen section will indicate the presence of dead pixels and the type of backlight.

⚠️ Note: Some apps may show inaccurate data on newer smartphone models if the utility database is not yet updated.Always double-check information from multiple sources.

Using third-party software is safe and does not require special permissions beyond the standard, but be careful with applications that require access to root rights or system files, as this can disrupt the security system of Xiaomi.

Comparison of characteristics of Xiaomi matrices

To understand the differences, we need to look at comparative analysis: different Xiaomi models use different panels even within the same series. For example, in the Redmi Note line, both IPS and AMOLED screens can be found depending on the region and year of release.

Note the PWM setting: On AMOLED screens, brightness is often regulated by frequent backlight blinking, which can be invisible to the eye but cause headaches in sensitive people. Xiaomi's settings often have a "Flicker Removal" or "Anti-flicker" option that is useful to activate.

Checking through ADB and computer

For advanced users who want to get the most accurate technical information, the USB debugging method is suitable. You will need a computer, cable and an installed ADB (Android Debug Bridge) package, which allows you to ask the system for the exact name of the display driver.

First, activate Developer Mode. Go to Settings → About Phone and quickly press 7 times on "MIUI Version" or "OS Version." Then, in the "Advanced Settings" menu, turn on "Debugging on USB." Connect your smartphone to your PC and type in the command line:

adb shell dumpsys SurfaceFlinger | grep -i "type\|name"

This command will list the connected displays and their properties. Look for lines that contain the words "built-in" or the names of the panel manufacturers. You can also use the adb shell getprop | grep display command, which will show the system properties associated with the screen.

• 🔌 Make sure that the phone has selected the mode "File Transfer" or "Debugging by" USB" plug-in.
• 💻 Drivers must be installed on the computer ADB teamwork.
• 📝 Save the log output to a text file to make it easier to search for keywords.

It is important to know: if in the lags ADB mention "mdss_mdp" In conjunction with a specific resolution, this indicates the use of a Qualcomm controller, which most often works in tandem with the AMOLED matrices in flagship models.

Frequent questions about Xiaomi displays

Users often encounter nuances that are not described in the official documentation, and the following are answers to the most popular questions related to determining the type of screen and the features of the operation of matrices in Xiaomi devices.

💡

Accurate knowledge of the type of matrix helps to adjust the color temperature and protect vision by choosing the optimal screen mode.

In conclusion, you can determine the type of display on Xiaomi in many ways, from simply viewing a black image to deep analysis through ADB. For most users, a visual test or Device Info HW application is enough. Remember that the quality of the picture depends not only on the technology, but also on the factory calibration of a particular panel.
