How to find out the exact screen resolution on Xiaomi phone

Owners of Xiaomi, Redmi and POCO smartphones often face the need to know the exact characteristics of the display, whether to customize graphics in games, calibrate fonts or simply out of curiosity about the technical details of their gadget. Standard marketing descriptions in stores rarely contain complete information about pixel density or real resolution at points, limited to a generic format name, for example, FullHD+.

Understanding how to find out the screen resolution on Xiaomi’s phone gives the user complete control over visual content and allows you to precisely select wallpaper or video files that will be displayed without distortion and compression artifacts. Android, which runs the MIUI or HyperOS shell, has a variety of diagnostic tools hidden even without obtaining superuser rights.

In this article, we will look at all the available methods, from simple methods through the system menu to the use of specialized utilities and engineering codes, you will learn to distinguish between physical and logical resolution, and understand why these indicators can differ in different applications.

Basic characteristics of the display: what you need to know

Before we get to the bottom of the game, it's important to understand the terminology, because manufacturers often mix concepts to make things easier. Screen resolution is the number of pixels horizontally and vertically that form an image, and it's this parameter that determines the clarity of the picture and the amount of information that is displayed.

The second key indicator is the density of pixels (PPI, Pixels Per Inch. It shows how many dots there are in one inch of diagonal. On Xiaomi devices with AMOLED-This parameter is often higher than on budget IPS-screens, which makes fonts smoother, but can affect interface scaling.

• 📐 Physical resolution: the real number of luminous elements of the matrix that cannot be changed software without damaging the system.
• 🖥️ Logical resolution: The virtual size of the workspace that can change when you turn on the "simple screen" mode or change the font size.
• 🎨 Color space: A parameter that affects saturation, but not the number of points, often customized in the menu".

It is worth noting that modern models of Redmi Note or flagship Xiaomi 13/14 uses Dynamic Resolution technology, which can dynamically reduce the resolution of rendering in heavy games to save battery power, although the native resolution of the matrix remains unchanged.

⚠️ Warning: Don't confuse screen refresh rate (60Hz, 90Hz, 120Hz) with resolution. Frequency is responsible for smooth animation, resolution is responsible for detailing static images.

Checking through the standard settings menu

The easiest and safest way to get basic information about the display is to use the built-in MIUI interface. However, manufacturers often hide the exact numbers, providing only a general description of the format. To access this data, you need to go to Settings → About Phone → All settings.

Here you'll see the "Resolution" line, where you'll see approximate values like 2400×1080. It's important to understand that the system can round up data or show logical resolution, which is used to build the interface, rather than the physical matrix. In some versions of the firmware, this information is hidden deeper.

If the standard path didn’t give you exact numbers, you can try activating advanced data through the developer menu, although it often shows the current zoom rather than the native screen properties.

💡

For quick navigation in settings, use the search for the word “About phone” in the top row of the settings menu.

Alternative path through settings → The screen and brightness may also contain useful information, especially if you have Eyepaper or Read Mode enabled, which can visually change perceived image quality, although the technical resolution remains the same.

Use of engineering menus and codes

To further diagnose the problem, Xiaomi engineers have provided a special hidden menu, accessible through a set of character combinations in the Phone app, which allows you to see technical information about the connected modules, including a detailed description of the display.

To get into the test menu, open the dialer and dial the code ##6484##. Immediately after entering the last star, the CIT (Customer Interface Test) list will open. Find the item associated with the display, usually called "Version Information" or simply "Display".

##6484##

In the window that opens, you'll find lines that contain the matrix codes and native resolution, and this is the most reliable source of information, because the data is read directly from the screen controller, bypassing the software shells of the system.

⚠️ Note: Do not change settings on the engineering menu that you do not know what you want to read. Resetting the screen calibration or changing the driver parameters may result in incorrect display of colors or the appearance of artifacts.

Third-party applications for detailed diagnostics

If the built-in tools seem not informative enough, specialized utilities come to the rescue from the Google Play store. Applications like AIDA64, Device Info HW or CPU-Z can read the full specifications of the hardware part of the smartphone, providing data in a convenient structured form.

Once you install this app, you need to go to the Display tab, and here you will see not only the current resolution, but also the physical size in inches, the pixel density (DPI), and the matrix type and color profiles supported, which is especially useful for comparing the claimed characteristics with the real ones.

Some apps also show the current screen refresh rate in real time, which allows you to check whether the claimed 120Hz mode is actually working in an open application, since the system can reduce the hertz for static content.

• 📱 AIDA64: Provides comprehensive information on all system components, including temperature and load.
• 🔍 Device Info HW: It specializes in camera and screen, even showing a sensor model.
• ⚙️ CPU-Z: A classic tool that quickly shows the basic parameters SOC display.

Using third-party software is safe if you download it from official sources, and these programs do not require root rights to display basic permission information.

Comparison of screen characteristics of different Xiaomi series

Xiaomi’s smartphone lineup is extremely diverse, and display options can vary dramatically even within a single year of release, and understanding these differences helps you gauge how well your device meets expectations.

The flagship Xiaomi Mi and Xiaomi Number Series (e.g., 13, 14) are traditionally equipped with top-end matrices with WQHD+ resolution (1440p) and high pixel density. At the same time, the Redmi Note series more often uses the FullHD+ standard (1080p), which is the gold standard for balancing quality and power consumption.

Note that in the budget segment, HD+ (720p) screens are common. At 6.5 inches and above, this can be noticeable to the naked eye in the form of “grain” fonts, if you do not look closely.

💡

Screen resolution is not the only indicator of quality: matrix type (AMOLED vs. IPS) and brightness are often more important for everyday comfort than the extra millions of pixels.

Impact of Permit on Performance and Battery

Many users are wondering if they should be worried about high resolution when the phone is only used for social media, and the answer lies in the balance between visual and resource intensity, and rendering a 2K or 1.5K interface requires more processing power than a GPU.

High resolution directly affects autonomy. The more pixels you need to light up and update, the more power the system consumes, which is why in power saving modes, Xiaomi often automatically reduces frame rates and can limit the maximum rendering resolution in games.

For gamers, knowing the exact resolution is critical. Setting graphics in the game on "Ultra" at native screen resolution can cause the processor to overheat and trottle, whereas lowering the rendering resolution in the game settings will add FPS without loss of quality on the small screen.

⚠️ Note: Forced change of system resolution through ADB-commands on modern versions of Android can lead to unstable interface, dropouts of applications and the inability to use touch input normally.

MIUI optimization usually chooses the best balance itself, but in games it is always better to set the settings manually, relying on the capabilities of your processor, not just the resolution of the matrix.
