The exact number of pixels in the Xiaomi Mi 8 Pro is often asked by users who want to evaluate the clarity of the picture before buying or try to adjust the interface for maximum comfort. This flagship device, which came to market as a more powerful version of the standard eight, is equipped with an advanced for its time matrix, the parameters of which still look relevant.
The main screen of the device is based on Super AMOLED technology, which implies not only deep black, but also high pixel density per inch. Standard resolution is 2248×1080 pixels, which in marketing materials is often rounded and called Full HD+. However, the physical structure of the matrix and the software interpretation of the resolution in the shell of MIUI have their own nuances, which are worth considering in more detail.
Understanding the real picture of pixels is important not only for theorists, but also for those who plan to use a smartphone to work with text, graphics or watch high-resolution video. In this article, we will discuss in detail the technical characteristics of the display, how to check the real resolution and the effect of pixel density on power consumption.
Technical characteristics of the Super AMOLED matrix
The display in the Xiaomi Mi 8 Pro occupies almost the entire front panel, having a diagonal of 6.21 inches. It is the combination of this diagonal and a resolution of 2248 by 1080 that gives the total pixel density of 403 ppi (pixels per inch), which is considered the “gold standard” for smartphones, since the human eye from a distance of 25-30 cm already has difficulty distinguishing individual points.
Using AMOLED technology means that each pixel glows on its own. Unlike IPS-matrixes, which use constant lighting, black is achieved by completely turning off the subpixels, which creates infinite contrast and saves battery power when using dark themes of design.
💡
Use a dark theme in the MIUI, to use only a part of the pixels of the screen, which will significantly extend the battery life AMOLED-display.
It is important to note that the subpixel structure in this matrix is Pentile, which means that the red and blue subpixels are larger and staggered, while the green subpixels are smaller and more frequent. This scheme allows you to increase the service life of organic elements and reduce energy consumption, although theoretically it can have a slight impact on the clarity of small fonts compared to the classical type. RGB-matrix.
Pixel density and influence on perception
The 403 ppi that the Xiaomi Mi 8 Pro provides is the result of complex engineering calculations. If the resolution were lower, for example, standard 1920×1080 without an elongated format, the density would fall, and diagonals over 6 inches could be noticeable "ladder" on the fonts. Increasing the number of pixels vertically to 2248 allowed you to maintain high definition at an elongated aspect ratio of 18.7:9.
⚠️ Attention: High pixel density requires a powerful GPU to render the interface. Make sure that the Developer Options settings do not set artificial rendering restrictions if you want to see the image in native quality.
The effect of pixel count on perception is directly related to the distance to the eyes. For a smartphone that is held in your hands, 400+ ppi is a comfortable level. At this resolution, font smoothing (anti-aliasing) works as efficiently as possible, making the text look like a printed one in a high-quality magazine.
The matrix in the Xiaomi Mi 8 Pro supports the wide color gamut of the DCI-P3. This means that each of the millions of pixels is capable of displaying more saturated and natural colors than the standard sRGB. Combined with high resolution, this gives stunning detail to photos and videos.
Software resolution and MIUI settings
Although the matrix has a fixed number of pixels, the Android operating system and the MIUI shell can programmatically scale the image. In standard mode, the Xiaomi Mi 8 Pro renders the interface in native resolution. However, the developer menu hides the possibility of changing the density of DPI (Dots Per Inch).
Changing the DPI allows you to resize interface elements without changing the physical number of pixels. If you set the DPI above the standard (usually around 400-420 for such screens), the elements will become smaller and more information will fit on the screen, which creates the illusion of even higher resolution, although the physical pixels remain the same.
To access these settings, you must:
- 📱 Go to Settings → About the phone and 7 times click on the version MIUI.
- 🛠 Open Extended Settings → For developers.
- 🔍 Find the "Minimum Width" (Smallest Width).
- ⚙️ Change the value, remembering the original.
⚠️ Attention: Do not set the value DPI Lower than 300 or above 600 without need, too low can make the interface unreadable, and too high can cause software failures in some applications.
Comparison with competitors and other models
To see how good the Xiaomi Mi 8 Pro screen is, it’s worth comparing it to other flagships of the period and modern counterparts. The table below compares the main display parameters.
| Smartphone model | Permission (pixels) | Diagonal | PPI |
|---|---|---|---|
| Xiaomi Mi 8 Pro | 2248 × 1080 | 6.21" | 403 |
| Samsung Galaxy S9 | 2960 × 1440 | 5.8" | 570 |
| iPhone X | 2436 × 1125 | 5.8" | 458 |
| OnePlus 6 | 2280 × 1080 | 6.28" | 403 |
As you can see from the table, the Xiaomi Mi 8 Pro is in the same weight category as the OnePlus 6, behind Samsung and Apple in terms of pixel density, which used matrices with Quad HD resolution and higher. However, the difference of 400 versus 570 ppi is noticeable only when looking at the screen under the magnifier or from very close range.
Xiaomi’s approach has benefited from optimization: the Full HD+ matrix on AMOLED consumes less power than Quad HD, which has a positive effect on autonomy. For most users, the difference in detail between 400 and 500 ppi is almost indistinguishable in everyday use.
💡
The Xiaomi Mi 8 Pro uses a balance between Full HD+ quality and energy efficiency, which is a reasonable trade-off for a 6.21-inch smartphone.
How to check the actual screen resolution
If you want to make sure your device has pixels or check if your settings are broken, you can use built-in tools or third-party utilities, and the easiest way is to use an engineering menu or special applications from Google Play.
One of the most reliable ways is to use ADB (Android Debug Bridge) via a computer, and by connecting your smartphone over USB and enabling debugging, you can input a command that will output the exact physical parameters of the display, which is especially useful if you find that the detector application is showing incorrect data due to the manufacturer's software crutches.
The command to check through ADB is as follows:
adb shell wm sizeIn response, the device will output a string of the form Physical size: 1080x2248. You can also use the command adb shell wm density to find out the current density of DPI. This data is "hardened concrete" and is taken directly from the display drivers.

Impact of permission on autonomy and productivity
The number of pixels directly affects the load on the GPU. The more dots you need to draw per second (especially in games or when animations of the interface), the more power the device consumes. Xiaomi Mi 8 Pro with its resolution of 2248×1080 is in the optimal zone.
When using navigation or watching video at 1080p, the load on the GPU is minimal, since the content coincides with the physical resolution of the matrix (pixel-to-pixel mapping). If the screen was Quad HD, the system would have to scale Full HD video, which adds additional computational costs, or the video would look less clear.
Besides, AMOLED-This technology saves power when displaying static dark-colored images, and because each pixel works independently, the black areas on the screen are simply turned off. Combined with a reasonable resolution, this allows the Xiaomi Mi 8 Pro to demonstrate good screen time performance.
