Owners of the Xiaomi Redmi Note 10 Pro smartphone often wonder how to change the resolution of the display to improve performance or, conversely, to improve picture clarity. MIUI Does not provide a direct button to switch between FHD+ and HD+, But there are proven ways to get around this limitation, and deep customization allows you to tailor your device to your personal preferences and needs.
There are two main approaches to changing display settings: securely switching the refresh rate through the standard menu and advanced DPI density setting through engineering codes. The first method is available to every user right out of the box, while the second requires caution, since it affects Android system files. Understanding the difference between these methods is critical for the stable operation of the gadget.
In this article, we will discuss in detail all available options for modifying the video output of your smartphone. You will learn how to activate hidden modes, what risks are associated with changing the density of pixels and how to return all settings to their original state if necessary. Careful study of the material will help avoid errors during settings.
Standard display settings in MIUI
Before you get to the tricky manipulations, you need to explore the basic features that the MIUI shell provides. In the standard settings menu, the user can adjust the refresh rate of the screen, which directly affects the smoothness of the interface and energy consumed. For the Redmi Note 10 Pro, this is especially true, since the AMOLED matrix supports a high hertz.
To find these settings, go to Settings → Screen → Screen Update Frequency. Here, the system will suggest choosing between standard mode and high frequency mode. Selecting the 120 Hz mode will ensure maximum smoothness of scrolling lists and animations, making the device more enjoyable.
⚠️ Warning: Forced 120Hz on some heavy games or applications can lead to increased battery consumption and heat up the smartphone case.
It should be noted that the standard matrix resolution in the Xiaomi Redmi Note 10 Pro is fixed at 2400×1080 pixels. The system automatically scales the content, but physically changing the number of active pixels through a regular menu is impossible.
💡
To save charge in everyday tasks (reading, social networks) you can temporarily switch to 60 Hz, and for games to return 120 Hz.
Change the DPI density through the developer settings
The most effective way to visually change the resolution is to adjust the dots per inch (DPI) parameter, which does not change the physical resolution of the matrix, but causes the system to draw elements smaller or larger, creating a resolution change effect.
The first step is to unlock the hidden features. Find the "About Phone" option in the settings and quickly press the MIUI version 7 times in a row. Once the message "You're a developer" appears, you can start setting up. Be careful, because the wrong values can make the interface unreadable.
Next, follow the Settings → Advanced Settings → Developer. In the list that opens, look for the “Minimum Width” option. Remember or write down the original value (usually around 392-411 dpi for a given model) to be able to return everything back.
- 📉 Reduce the value DPI Makes interface elements smaller, visually freeing up more space on the screen.
- 📈 Increased importance DPI Enlarges fonts and icons, which is useful for people with impaired vision.
- ⚙️ Changing the parameter is instantaneous, but requires rebooting for some applications to work properly.
☑️ Checking before change DPI
Using the Engineering Menu for Testing
To test the display in depth, you can use Xiaomi’s engineering menu, which is designed for service centers, but also available to ordinary users, and allows you to check the sensor performance, color gamut and the presence of broken pixels, which is important when assessing image quality after changing settings.
You enter the menu through a standard dialer, you enter a special combination of characters, then the diagnostic interface opens, and you can run tests on the uniformity of the backlight and the accuracy of the color reproduction of the AMOLED matrix.
##6484##In the display-related section (usually labeled Display or LCD), tests of different colors and gradients are available, which helps to identify artifacts that may have emerged after changing the screen's software settings. If you notice strange stripes or flickering, it's recommended to reset.
⚠️ Warning: Do not change the parameters in the engineering menu unless you are sure of their purpose.Accessual activation of test modes can block the normal operation of the touch screen.
What happens if the screen turns black after the DPI change?
Comparison of matrix modes
Understanding the specifications of your Redmi Note 10 Pro will help you make an informed decision about settings. Different display modes have their advantages and disadvantages, which directly affect the user experience. Below is a table comparing the main parameters.
| Parameter | Standard regimen | High frequency (120 Hz) | Low resolution (emulation) |
|---|---|---|---|
| Smoothness | 60 Hz (standard) | Maximum | Depends on the DPI. |
| Energy consumption | Average. | High. | Reduced |
| Clearness of text | Tall. | Tall. | Medium/Low |
| GPU loading | Normal. | Elevated | Reduced |
As you can see from the table, choosing between performance and picture quality is always a trade-off: 120Hz mode provides better animation, but it puts the battery down faster. Emulating low resolution via DPI can take a little bit of GPU load in older games, whines about font clarity.
For everyday use, the best option is to balance: standard resolution with adaptive refresh rates. The system itself switches between 60 and 120 Hz depending on the content on the screen, saving charge without losing comfort.
The impact of screen settings on performance
Changing display parameters, especially point density (DPI), can indirectly affect the overall performance of a smartphone. When setting very low DPI values, the system has to render more objects per inch, which increases the load on the graphics chip. This can lead to micro-freezes in the interface.
On the other hand, zooming (high DPI) reduces the load on rendering as elements become smaller, but this does not produce a significant increase in FPS in games, since game engines often have their own resolution settings independent of the system, and the main effect is felt in the speed of the MIUI interface.
If you notice that after the changes, the phone started to work slower, it is worth checking the temperature of the processor. Overheating can cause trottling, which slows down the entire system, regardless of the screen settings, in such cases, it is recommended to return the standard values.
- 🚀 Decline DPI It can speed up multitasking by allowing you to see more windows at the same time.
- 🐌 Excessive zooming makes navigation uncomfortable and requires high accuracy of finger hits.
- 🔋 High screen hertz – the main consumer of energy after the processor and communication module.
💡
The optimal balance between performance and picture quality is achieved with standard settings recommended by the manufacturer.
Possible problems and solutions
Experiments with the system settings of the screen on the Xiaomi Redmi Note 10 Pro do not always go smoothly. Users may face incorrect display of fonts “got” layout in applications or complete disappearance of the image. It is important to know how to act in such situations, so as not to carry the device into the service.
The most common problem is setting an extremely low DPI when the interface becomes so small that you can't access the menu buttons, and in this case, blind input or using a voice assistant to return settings helps, and you can also use a Recovery menu reset.
If you lose color calibration or artifacts after the refresh rate changes, try switching the theme to standard. Sometimes custom themes conflict with new rendering options, causing visual glitches. Resetting factory settings through the reset menu is a radical but effective method.
⚠️ Warning: If the screen stopped responding to touch after the change DPI, plug in USB-mouse-wise OTG-Adapter to control the interface and fix the settings.
Regularly updating MIUI firmware can reset user DPI settings. This is normal system behavior, which is designed to ensure stability after installing security patches. Just repeat the setup procedure after the update.
