How to Calibrate Xiaomi’s Screen: The Complete Guide to Setup

Xiaomi smartphone owners often face a situation where the image on the display seems unnatural, too cold or, conversely, too warm. Standard factory settings of screen calibration do not always take into account the individual preferences of the user or the peculiarities of color perception by the human eye. That is why the question of how to calibrate the Xiaomi screen remains relevant for those who want to get the best picture.

The color rendering process can vary depending on the device model and the firmware version of MIUI or HyperOS. Some users notice that after updating the system, colors become faded or an unwanted shade appears. In this guide, we will discuss all available correction methods, from basic system settings to advanced tools for enthusiasts.

Not only does a good display setting improve the visual experience when viewing photos and videos, but it can also reduce eye strain when using the gadget for a long time. It's important to understand that calibration is a delicate process that requires attention, but the result is worth it.

Basic display settings in MIUI and HyperOS

The first step to a perfect picture is to use the built-in tools of the operating system. Modern shells from Xiaomi offer a fairly flexible way to change the display parameters without the need to install third-party software. First, you need to go to the Settings menu. → Screen.

Here you will find the Color section, which offers several preset modes: Saturated, Standard and Enhanced. The Saturated mode is often used by default and makes the picture bright, but can distort real shades. The Standard mode brings the color reproduction closer to the sRGB standard, which is useful for viewing photos.

The Color Temperature feature is also available on this menu, and by moving the slider, you can shift the white balance to warm (yellowish) or cold (blueish) shades, which helps to compensate for the individual matrix of a particular smartphone instance.

• 🎨 Saturated: Makes colors more vivid and contrasting, ideal for gaming and video.
• 📐 Standard: Provides the most accurate color reproduction for graphics.
• 🌡️ Color Temperature: Manually adjusting white balance from cold to warm.

⚠️ Warning: Changes in color temperature affect all apps at once.If you set a too warm hue, white pages in the browser may look yellow, which is not always comfortable to read.

Remember that some models have a DCI-P3 option that extends the color gamut, which makes the image more lively but can consume a little more battery power.

Use of the Engineering Menu for Calibration

For a deeper setup that advanced users can access, there is an engineering menu, and this hidden partition allows you to adjust the display settings at a lower level, so to get there, open the Phone app and type the combination ##6484##.

In the CIT (Customer Interface Test) menu that opens, you need to find a item associated with the display, which can be called "Display", "Screen" or "Color." Inside this section, broken pixel tests are often available, but there can also be hidden sliders to adjust the gamut.

Be extremely careful when changing the values in the engineering menu. Incorrect settings can cause the image to become unreadable, and you have to perform a full reset or flash the device.

In some firmware versions, access to the color calibration in the engineering menu is blocked by the manufacturer, in which case the system will issue a message about the restriction of access or simply do not show the corresponding sliders.

• 🔧 Access: dial ##6484## in the app calling.
• 📉 Functional: matrix testing and basic color channel adjustment.
• ⚠️ Caution: Any changes are made at your own risk.

⚠️ Warning: Engineering menus are for service centers, inexperienced interventions can disrupt not only the screen, but also other components of the smartphone.

Third-party applications for screen calibration

If built-in tools are not enough, specialized applications from the Google Play Store come to the rescue, and SecondScreen, which allows you to manage display profiles, refresh rates and color gamuts, has long been considered the leader in this area.

These programs often require advanced rights or the use of ADB (Android Debug Bridge), a computer utility that allows you to send commands to a smartphone from a PC. By connecting the device over USB, you can activate the desired color reproduction profiles that are not available in the regular menu.

Other applications, such as Screen Balance or Blue Light Filter, work by overlaying a color filter over an image, and they don't change the physical calibration of the matrix, but they do effectively adjust the user's perception of color.

Blue light filters are especially important in the evening, making the screen more yellow, which reduces the effect of blue spectrum on melatonin production and helps you fall asleep faster.

Configure through ADB teams

For those who are not afraid of the command line, the method is used ADB It's one of the most efficient ones, and it allows you to activate hidden display modes that the manufacturer might have blocked in the interface. USB" in the About Phone section, quickly clicking on the build number.

Once you connect your smartphone to your computer and install the drivers, you can type in special codes in the PC command line, for example, a command to switch color modes may look like changing the value in the Android settings database.

adb shell settings put global display_mode 2

The value of the parameter can vary depending on the model of the device. For some smartphones, "2" means standard mode, for others - saturated.

💡

Before making changes through ADB, write down the current values of all display parameters so that everything can be returned in case of an error.

And you can also turn off the automatic brightness control, which often interferes with manual calibration, through ADB, which gives you complete control over the backlight of the array.

• 💻 Tool: platform SDK Platform-Tools by Google.
• 🔌 Connection: Quality is required USB-cable.
• 📝 Commands: entered in the terminal on the computer or through the emulator application on the phone itself.

⚠️ Note: The wrong command in the ADB This can cause a bootloop to cycle, always check the syntax of the commands before executing them.

Elimination of yellowness and unevenness of backlight

One of the frequent problems AMOLED-Xiaomi's screens have what's called "yellowness" at the bottom of the display or at the edges. It's a design feature of many matrices, but it can be visually hidden.

If yellowness is caused by a software glitch, resetting the screen settings can help, in some cases, switching the screen refresh rate from 60 Hz to 120 Hz and back again helps - this restarts the display controller.

For OLED-The screens also have a PWM effect, and people with sensitive eyes are advised not to dim their brightness below 30%, as at low values, flickering becomes more noticeable and can cause fatigue.

💡

Software calibration will not correct a physical defect in the matrix, but it may make it less visible to the human eye.

If there are spots or stripes on the screen that do not disappear after calibration, there is likely physical damage or burnout of organic LEDs, in which case the software methods are powerless.

Testing of results and testing

After all the manipulations you've done, you need to check the results, and the best way to do that is to open a quality photo or video that you know well, and compare it to another device or printout, and look at the skin tones and the white color of the paper.

It's also useful to use special test images to check for gradients, which help to identify "banding" (stepping color transitions) and make sure that the calibration did not introduce artifacts.

Let your eyes get used to the new settings within a few hours. A sharp change in color temperature may seem strange at first, but after a while you will appreciate the naturalness of the image.

• 👁️ Visual test: comparison with reference image.
• 📊 Gradients: checking the smoothness of the transitions from black to white.
• ⏳ Adaptation: Time is needed to adjust to new colors.

If the result does not suit you, you can always return to the factory settings in the Screen menu by clicking the Reset button or selecting the default profile.
