Xiaomi smartphone owners often face the need to accurately define the characteristics of their device. The question of how to find out the resolution of the Xiaomi screen becomes especially relevant when installing specific wallpaper, setting up emulators or choosing accessories. Modern displays offer incredible detail, and understanding the real number of pixels helps unlock the potential of the gadget.
Determining image density is important not only for enthusiasts, but also for ordinary users who want to evaluate the quality of the picture. Different product lines, whether it is the flagship Xiaomi Mi or the budget Redmi Note, can have radically different matrix parameters. In this article, we will discuss all the available ways to obtain accurate information without installing third-party software.
Knowing the exact display settings allows you to properly configure the interface scaling, which is especially useful if the standard font settings seem too small or cumbersome to you. Let's look at what tools the Android operating system itself provides and the MIUI or HyperOS shell.
Checking through standard system settings
The easiest and safest way to know the characteristics of a display is to use a built-in menu. You don't have to be a technician to find the data you need. The MIUI shell interface is designed to make the basic information available in a couple of clicks.
To start, open the Settings app on the home screen. Scroll down to the bottom and find the About Phone section. This is where the basic information about the model, the processor, and, importantly for us, the display is collected. In some versions of the firmware, the resolution data may be hidden, but most often it is listed immediately under the model name.
If you only see a diagonal in the basic menu, try clicking on the MIUI version or Android version several times in a row.This action can open an extended engineering test menu or hidden specs, where the exact size in pixels will be specified, for example, 2400×1080.
- 📱 Open the Settings menu and go to About Phone section.
- 🔍 Look for a line with the model name or the permission graph.
- ⚙️ Try tapping the build number to access hidden data.
- 📏 Pay attention to the aspect ratio, it is often indicated next to the diagonal.
⚠️ Note: In some global firmware versions, Xiaomi hides the exact resolution in the standard menu, leaving only the marketing name (e.g., "Full"). HD+").
It is worth noting that in new versions of HyperOS, the company is striving to simplify the interface, so detailed specifications can be brought to a separate submenu or only available through special codes.
💡
The standard About Phone menu is the first and most secure source of information, but it doesn’t always show the exact number of pixels explicitly.
Use of the engineering menu and USSD-code
When the standard settings are silent, the engineering menu comes to the rescue, and it's a powerful diagnostic tool built into the firmware of every smartphone, and it uses special combinations of characters that are entered like a regular phone number.
Open the Phone app and dial ##6484##. If the code is entered correctly, the CIT menu will automatically open on the screen. Here is a long list of tests for all components of the device. You need to find the item associated with the display, it can be called Version Information, Display or Screen.
Within the test mode, you can often see not only the current resolution, but also information about the matrix manufacturer, temperature, and even conduct a color test. Be careful: changing the settings in the engineering menu can affect the color calibration or touch screen.
- 📞 Open the dialer and enter ##6484## to enter the dialer. CIT.
- 🧪 Find the Version Information or Display test in the list.
What if the code doesn't work?
Another useful code is ##4636##. It opens the testing menu, where you can sometimes find additional technical information in the Phone Details section, although it is more often related to the network and battery. However, it is worth checking, since the content of the menu can vary depending on the version of Android.
⚠️ Attention: Engineering menus are for service centers.Accessual change of parameters in sections marked as Debug or Calibration can lead to incorrect display of colors.
Using codes is a quick way to access the system's "enterprises" without superuser rights, but if you want the most detailed data, including pixel density (DPI) and physical size in inches to within a hundredth of a hundredth, you'd better use specialized utilities.
Third-party applications for detailed diagnostics
If the built-in tools don't seem informative enough, Google Play Store apps will come to your aid, and they read data directly from system files and output it in a convenient, structured way, and this is the most reliable way to know the real resolution and physical size of the matrix.
One of the most popular and proven tools is the AIDA64 app. Once installed, launch it and go to the Display tab, and here you will see comprehensive information: resolution in pixels, physical size in inches, pixel density (DPI), aspect ratio, and even sensor information.
Another powerful tool is Device Info HW. This application is especially useful for advanced users, as it shows not only the resolution, but also the type of matrix, supported video codecs and about the GPU. For the average user who just wants to know the screen size, a free version will be enough.
☑️ Criteria for choosing an application for diagnosis
It's important to understand the difference between physical resolution and logical resolution. In applications, you can see two values. Physical is the actual number of pixels on the matrix (e.g., 3200×1440). Logical is the resolution that the operating system sees to render the interface, it can be smaller because of camera cutouts or system navigation bars.
- 📲 Download. AIDA64 or Device Info HW log-store.
- 📊 Go to the Display section to view the features.
- 👁️ Note the difference between physical and logical resolution.
- 💾 Save the report (Snapshot) if you plan to compare devices.
Using third-party software gives you the most complete picture, and you can not only find out the numbers, but also understand what technology your screen uses: AMOLED, IPS or Super AMOLED, which directly affects color reproduction and power consumption.
Comparison of screen resolutions in Xiaomi lines
Understanding what resolution is the standard for different classes of devices will help you navigate the specs faster. Xiaomi uses different matrixes depending on the price segment of the smartphone.
In the low-end segment, represented by the Redmi and POCO M series, the most common screens are HD+ (1600×720) or Full HD+ (2400×1080) screens, which is the optimal balance between image clarity and energy efficiency. For diagonals up to 6.5 inches, this resolution is quite enough.
The flagship models of the Xiaomi series and POCO F is often equipped with screens with a resolution higher than Full HD. Here you can find it. 1.5K (2712×1220) or 2K/4K (3200×1440 These displays provide incredible detail, especially noticeable when watching high-quality video or in use. VR-headset.
| Class of device | Typical authorization | Density (DPI) | Example |
|---|---|---|---|
| Budgetary | 1600 × 720 (HD+) | ~295 ppi | Redmi A / C |
| Medium. | 2400 × 1080 (FHD+) | ~395 ppi | Redmi Note / POCO X |
| Subflagship | 2712 × 1220 (1.5K) | ~440 ppi | Xiaomi 13T / POCO F5 |
| Flagship | 3200 × 1440 (2K/WQHD+) | ~520+ ppi | Xiaomi 14 Ultra |
Keep in mind that manufacturers often use marketing names such as CrystalRes or DotDisplay, which do not indicate a specific resolution, but rather indicate production technology or calibration features, so checking with the table and real data through applications will always be more useful.
💡
When choosing wallpaper, always focus on the physical resolution of the screen, and if you upload a smaller image, the system will stretch it, leading to soaps and artifacts.
Impact of Permit on Performance and Battery
Many users are asking themselves, is it worth worrying about high resolution? The answer lies in the balance between image quality and system resources. The more pixels you need to draw to the CPU and GPU, the higher the load on the GPU and RAM.
In heavy graphics games, the difference can be significant: on a 2K screen, the phone will heat up more and discharge faster than on a Full HD screen, all other things being equal, which is why you often find the option of lowering resolution in game tweeters and developer settings.
But for everyday tasks like social media, browser and video, the power difference between FHD+ and 2K on today’s Snapdragon processors is almost offset by optimization, and on high-pixel-density screens, fonts look sharper, which reduces eye fatigue during long reading.
⚠️ Attention: Decrease in the resolution in the developer settings may cause some interface elements to display incorrectly or float. Use this feature with caution.
If you notice that your smartphone is rapidly running out or slowing down in heavy applications, it makes sense to check if you're forced to have the maximum resolution if you're a mid-range device. Sometimes the system itself offers "Energy Saving Mode," which dynamically lowers the resolution.
Frequent questions and problems with definition
Even with all of the methods described, users may encounter nuances, such as changing menu numbers after updating the firmware, or showing different data from what the box says, often due to the way the system masks the cutouts as a front-facing camera.
There is also the concept of "efficient resolution." Because of the rounded edges of the screen (2.5D or 3D glass) and the software framework, some of the pixels around the perimeter may not be used to output a useful image, which is why there may be 10-20 pixel discrepancies in technical specifications and in the system.
If you reflash your phone to the global Chinese version, the model data may not be displayed correctly, but the screen resolution will remain a physical property of the matrix and will not change. Software failures rarely affect this setting unless the display driver has been damaged.
- 🔄 After the software update, double-check the data, as the logical resolution may have changed.
- 🇨🇳 In Chinese firmware, the data can be in Chinese, use a picture interpreter.
- 🛡️ Antiviruses and cleaners can block access to system files with hardware information.
Understanding these nuances will help you not panic if the numbers vary slightly from source to source, but the key is to know the physical limit of your matrix, which is the constant.
