How to Improve the Screen Quality on Xiaomi’s Android Phone: A Complete Guide

Xiaomi smartphone owners often find that standard display settings do not satisfy their visual preferences, making the picture too cold, faded or, conversely, overly saturated. Image quality directly affects the user experience, whether it is watching video, reading text or mobile gaming, so the correct calibration of the matrix is critical. Many users do not even suspect that their device is able to display much more color shades if you adjust the software settings correctly.

The MIUI or HyperOS shell interface provides a wide range of fine-tuning tools, but they are often hidden in the depths of system menus or require activation through engineering codes. In this article, we will examine all available methods, from basic sliders in settings to advanced calibration methods that will make the most of the AMOLED or IPS matrix of your device.

Before you start making radical changes, you need to understand the current state of the display and the goals you want to achieve. Don't blindly copy the settings from other devices, as each model has unique pixel characteristics and factory calibration.

Basic setting of image parameters in MIUI

The first step to improving the quality of the picture should always be to review the standard settings that the manufacturer offers. → The screen hides the basic controls that allow you to tailor the output of the image to your personal preferences, and you can change the color scheme by choosing between saturated, standard or improved colors, which dramatically changes the perception of content.

Special attention should be paid to the function of Adaptive brightness, which automatically adjusts the backlight depending on the lighting around. Although this is convenient for saving energy, the algorithm often works incorrectly, making the screen too dim indoors or excessively bright at night, it is recommended to turn off automatic adjustment and set the brightness level manually to achieve a stable and predictable result.

⚠️ Note: Setting maximum brightness for a long time can lead to accelerated burnout of pixels on the AMOLED-screens and overheating of the device body.

Also important is the screen refresh rate if your smartphone supports 90Hz or 120Hz. Switching to a high frequency makes the interface smoother, but can affect color reproduction in some applications. In the screen settings section, make sure that the default or high mode is selected so that the system itself switches between modes depending on the content.

💡

For a more accurate assessment of color rendering, use special test images or calibration apps, not just everyday apps.

Calibration of color reproduction and temperature conditions

Color temperature is one of the most subjective parameters that directly affects how we perceive screen quality. By default, Xiaomi often sets a cold shade with a bias towards blue to make the image appear brighter and contrasting, but this distorts the real colors. For those who are engaged in photo processing or just prefer natural colors, you need to shift the temperature slider towards warm shades.

In the advanced screen settings available on some models, you can find a color wheel, where you adjust it through separate channels RGB. This allows you to correct specific distortions, for example, remove the greenish tint on a white background or add paint to red colors. If there is no standard color wheel, you can use the "Paper" or "Vision Protection" mode, which software filters the blue spectrum.

• 🎨 Saturated colors - mode for bright wallpaper and games, increases contrast.
• 📄 Standard Colors – The closest to reality sRGB color reproduction.
• 👁️ Improved Colors – An attempt to expand the color gamut to support P3.
• 🌙 Reading mode – monochrome or sepia mode to reduce eye strain.

Remember that any changes in color are best checked on a variety of content: photos of people, landscapes and texts. Excessive heat can make the skin in photos unnaturally red, and cold spectrum will turn a white sheet into blue.

Using Hidden Engineering Menus for Display

For power users who don’t have enough standard settings, there is a hidden engineering menu where you can make in-depth diagnostics and adjustments to display settings, which is accessed through a set of special code in the call app, which opens up access to hardware tests and software configurations.

To get into the menu, you need to dial ##6484## or #4636##, and then the CIT (Customer Interaction Test) will open, where you can run broken pixel tests, check the sensor and evaluate the uniformity of the backlight. Some firmware versions allow you to recalibrate the screen to factory values through this menu if you had the previous one!

⚠️ Warning: Changing the parameters in the engineering menu without understanding their purpose can lead to improper display performance or loss of warranty.

The Single Item Test section often features a Display or Color item where you can see technical data on the current color temperature in Kelvins, and knowing these values, you can more accurately match the settings in the standard menu or third-party applications, and check for "dead" pixels, which can manifest as black or white dots on a monotonous background.

Increased resolution and DPI density

One way to visually improve font clarity and fine interface elements is to change the density of dots per inch, known as DPI (Dots Per Inch).The standard value for most Xiaomi smartphones varies between 360-400 DPI, but changing it can make the picture more detailed, although it will reduce the size of the interface elements.

To change this setting, you need to activate the developer mode by clicking on the MIUI version several times in the About Phone section. Once activated, you need to find the Smallest Width menu. Increasing the DPI value makes elements smaller, which creates the illusion of higher resolution, but requires caution.

Recommended DPI values:


360 is the standard value




400 – slightly smaller, convenient for larger screens




480 – greatly reduces the interface, increases detail




>500 – may cause application compatibility issues

Keep in mind that too high a DPI can make some interface elements unreadable or cause system applications to crash. If the screen or strange artifacts go out after changing the values, the device usually resets the settings after 15 seconds, but it is better to be ready for a forced reboot.

Third-party applications for calibration and configuration

If built-in tools aren’t enough, Google Play’s customized apps help manage color temperature and gamut at the software level. One of the most popular solutions is the Screen Balance app, which gives you access to fine-tuning color balance without having to edit system files.

Another powerful tool is Twilight, or the built-in Read Mode, which not only filters blue light, but can also adjust the overall brightness below the minimum threshold set by the system. AMOLED-screens, where at minimum brightness can be observed PWM (shimmering), harmful to the eyes.

• 📱 Screen Balance – Deep Color Channel Customization RGB.
• 🌙 Twilight – Smart color temperature control by time of day.
• 🎨 Color Calibration – creating profiles for different types of content.
• 👁️ Blue Light Filter: A simple reduction of the blue spectrum for comfort.

Using third-party software requires special permissions, such as "Overlapping Other Windows," which gives the app control over the output of the image, which may slightly increase battery consumption, but provides unparalleled customization capabilities.

💡

Third-party applications do not change the physical matrix, but rather impose a software filter, so they can be disabled at any time without a trace.

Removing flickering (PWM) and artifacts problems

Owners of smartphones with AMOLED arrays often complain of screen flickering at low brightness, known as PWM (Latitudinal Pulse Modulation), a phenomenon caused by the fact that to reduce brightness, the screen quickly turns on and off, which can cause eye fatigue and headache in sensitive users.

Newer versions of HyperOS and MIUI 14 have added an "anti-PWM" or "Flicker Removal" feature, which you can find in special features or screen settings, activating this mode changes the backlighting algorithm, making the flicker less noticeable or eliminating it altogether, although this can slightly change the color reproduction at minimal brightness.

If the flicker is not eliminated programmatically, the only way out is to use the "Paper" mode or set the minimum brightness above the threshold where active flickering begins. Also, using dark themes of design helps, since the AMOLED screen pickles are simply turned off against a black background.
