Owners of Xiaomi Redmi Note 8 often face the need to clarify the technical parameters of their device, in particular, the characteristics of the display. This may be necessary when choosing a protective glass, adjusting graphics in demanding games or diagnosing possible hardware malfunctions. Understanding what resolution is set by default helps to better manage the autonomy and performance of the gadget.
Many users mistakenly believe that pixel information is only available in documentation or on a box, but the MIUI-enabled Android operating system provides many built-in tools to verify this data. In this article, we will take a look at everything from simple settings menus to the use of specialized utilities.
It is important to note that the correct definition of the parameters of the matrix is necessary not only for enthusiasts, but also for ordinary users who want to optimize the operation of the interface. Next, we will consider step-by-step algorithms of actions that will allow you to get accurate information in minutes without having to connect to a computer.
Check through the standard MIUI settings menu
The most obvious and safe way to learn basic display parameters is to look at the system settings of your smartphone. In the MIUI shell that is installed on the Redmi Note 8, this information is not hidden deep, but requires careful navigation. You need to open the Settings app and find the About phone section.
Inside this section, you can see basic information about the processor model, the Android version, and, importantly for us, the screen settings. However, the standard menu often only shows the diagonal and matrix type, without specifying the exact number of pixels vertically and horizontally.
Here you'll see the resolution bar, where you'll see exact numbers like 1080 by 2340 pixels, which determines image density and font clarity, and if that menu doesn't show data explicitly, which is what happens in some firmware versions, you should use alternative methods.
⚠️ Note: Do not try to change screen settings in hidden engineering menus without first creating a backup, as incorrect settings can lead to inoperability of the interface.
💡
Before making any changes to system files or display settings, take a screenshot of the current settings to be able to return to the original state.
Using the Engineering Menu for Diagnostics
For a deeper diagnosis of the Xiaomi Redmi Note 8 display, there is a special mode known as the Engineering Menu or CIT (Customer Integration Test), which is designed to test hardware components and see the real state of the matrix. To get there, open the Phone application and type the combination ##6484##.
Once you enter the code, you automatically open the test list, and you need to find the item associated with the display, usually called Version or Display. In some versions of MIUI, you can access the full technical report through the Version menu in the phone settings, where you need to repeatedly click on the MIUI version.
The engineering menu displays not only software permissions, but also the physical limits of the matrix, which is especially useful if you suspect that the phone has been re-flashed or modified, and you can see the native resolution that the manufacturer has put in place and compare it to the current system settings.
- 📱 Open the dialer and enter the access code to CIT.
- 🔍 Find Version or Display Info Test in the List.
- 📊 Write down the width and height in pixels.
What if the code doesn't work?
Application of third-party application analyzers
If Xiaomi’s built-in tools don’t seem informative enough, the best solution is to install specialized software from the Google Play store. There are many free utilities, such as AIDA64, CPU-Z or Device Info HW, that read data directly from the system and output it in a convenient format.
Once you install an application like CPU-Z, launch it and go to the Device or Screen tab, and here you'll see not only the current resolution, but also the pixel density (DPI), refresh rate, and even the display driver information, which is indispensable when debugging games or setting up emulators.
The advantage of such programs is their versatility: they show information in the way the operating system sees it, eliminating possible marketing tricks. In addition, applications can show whether the Redmi Note 8 is running in compatibility mode or whether it uses full screen area.
| Annex | Size | Informativeness | Advertising |
|---|---|---|---|
| CPU-Z | Minimum | Tall. | Absent. |
| AIDA64 | Medium. | Maximum | It's in the free version. |
| Device Info HW | Small. | Medium | Minimum |
| Screen Info | Minimum | Basic | Absent. |
Technical characteristics of the display Redmi Note 8
To check the data with reference, here are the official screen specifications for the Xiaomi Redmi Note 8. The device is equipped with an IPS-matrix with a diagonal of 6.3 inches. Standard resolution is 2340 × 1080 pixels, which corresponds to the format Full HD+.
The pixel-per-inch (PPI) density in this model is 409, which provides high-definition images in which individual dots are not visible to the naked eye. The 19.5:9 aspect ratio allows you to comfortably use a smartphone with one hand and effectively work with multimedia content without black fields.
It is important to distinguish between the Redmi Note 8 and the Pro version, as they may not only have different processors, but also the calibration of the display. The standard version uses Corning Gorilla Glass 5, which also affects the optical properties of the screen, such as brightness and color reproduction.
- 📐 Diagonal: 6.3 inches.
- 🖼️ Type of matrix: IPS LCD.
- ✨ Density: ~409 ppi.
⚠️ Note: If you see a resolution significantly below standard in the analyzer applications (e.g, 720p instead 1080p), This may indicate that the operation is in energy saving mode or the presence of a system failure.
Size settings for elements and DPI
Redmi Note 8 users often confuse the physical resolution of the matrix with the software scale of the interface. Android has a feature to resize elements that changes the density of the DPI, making fonts and icons larger or smaller, but does not change the number of physical pixels.
To access these settings, activate the Developer Mode. Go to Settings -> About Phone and quickly click on the MIUI version seven times. Once the "You've become a Developer" notification appears, go to Advanced Settings -> For Developers.
In this menu, find Smallest width, which allows you to adapt the interface to your preferences, but remember that setting an DPI too high can make some controls unclickable.
☑️ Interface configuration
By experimenting with DPI, you can visually improve the perception of information on a Full HD+ screen, making the picture more compact and roomy, especially for those who use a smartphone to read documents or work with spreadsheets.
Impact of Permission on Performance and Gaming
Understanding the real screen resolution is critical for gamers. The Snapdragon 665 processor installed in the Redmi Note 8 is capable of handling graphics in Full HD, but in heavy games, lowering the rendering resolution can significantly boost FPS (frames per second).
Many emulators and launchers allow you to force the resolution to run games. Knowing the native parameters of 2340x1080, you can set a smaller value, such as 1600x720, to unload the Adreno 610 graphics accelerator, which will extend battery life and reduce the heating of the case.
However, it is worth considering that using non-standard resolution can lead to font blurring or incorrect positioning of controls in games.
💡
Decreasing the resolution in the game’s graphics settings is the most effective way to improve performance on the Redmi Note 8 without losing texture quality.
