Professional screen calibration on Xiaomi Redmi Note 8 Pro

Modern smartphones, including the popular Xiaomi Redmi Note 8 Pro, are equipped with high-quality IPS-matrixes, but the factory color settings are often far from ideal. Manufacturers tend to overstate the color saturation and temperature to make the picture look brighter on the store shelf, but in reality this leads to an unnatural yellow or cold blue shade.

The setup process does not require superuser rights or flashing the device. The display can be calibrated using the standard MIUI shell, as well as through hidden engineering menus that are open by default. Competent settings will help reduce eye strain during long reading and make colors more natural by removing intrusive color filters.

In this guide, we will take a look at all the customization methods available, from basic menu switches to fine adjustment through engineering mode, and learn how to eliminate the yellowness that is characteristic of many Redmi panels, and how to adjust automatic brightness for comfortable use of the gadget at any time of the day.

Basic Color Scheme Customization in MIUI

The first step to a perfect picture is to work with standard system settings. The MIUI shell provides the user with several preset profiles that change the gamut and color saturation. To access them, you need to go to Settings → Screen → Color Scheme. There are usually three options available here: saturated colors, standard colors and improved colors.

The default "Saturated Colors" mode makes the image very bright, but often distorts the real tones, making the skin in the photos reddish. Switching to "Standard Colors" (sRGB) immediately removes the excessive saturation, bringing the image closer to how it was intended by the content authors. The color profile in this mode is the most accurate for everyday use.

⚠️ Attention: After changing the color scheme, it may take a few minutes for the eyes to get used to the new picture.

Additionally, this menu often features a color temperature slider. By moving it, you can shift the white balance from cold blue to warm yellow. For the Redmi Note 8 Pro, the optimal position is often closer to the cold edge to compensate for the natural yellowness. IPS-panels, but it is a matter of individual taste.

• 🎨 Saturated: maximum brightness and contrast, but distorted colors.
• ⚖️ Standard: the most accurate sRGB color reproduction for photos and videos.
• 👁️ Improved: Automatic image optimization based on content.

Use of reading and night lighting mode

A vision protection feature known as Read Mode or Night Mode is often turned on by users accidentally or works incorrectly, placing a strong yellow filter on the entire screen, which can create the false impression that the phone screen is defective or requires complex calibration. You can check the status of this function by the Settings path. → Screen. → Reading mode.

You can set a blue light filter schedule here. If you notice that the screen is unnaturally yellow, make sure that the Add Shade switch is turned off or that the slider is pushed to a minimum position. The blue light filter is only useful in the dark, it only worsens the perception of information during the day.

The Adaptive Adjustment feature is worth noting, and it automatically changes color temperature depending on the time of day. For the Xiaomi Redmi Note 8 Pro, this feature is implemented quite gently, but if you want constant cold light, it is better to turn it off to exclude any automatic interference with color reproduction.

The way to check quickly:


Settings -> Screen -> Reading Mode -> Disable "Add shade"

It's important to understand the difference between software dimming and real calibration. Reading doesn't change the physical color rendering of the matrix, it just imposes a software filter. To calibrate properly, all such "improvers" should be turned off to see the real picture.

Fine tuning through the Engineering Menu (CIT)

For more advanced users who don’t have enough standard settings, the CIT (Customer Integration Test) is a hidden part of the system designed to test hardware components, including the display, and can be logged in by typing in the phone book code ##6484## or ##4636###.

You have to find a display item in the CIT menu, usually called Display or LCD Test. You can test for broken pixels, check the uniformity of the backlight, and most importantly, see the technical parameters of the current matrix. Some versions of MIUI allow you to reset the display settings to factory settings through this menu, which is useful if previous experiments with colors have gone too far.

⚠️ Warning: Be extremely careful in the engineering menu. Changing unknown parameters can cause the touchscreen or display to malfunction. Only change the settings that you are 100 sure of%.

There is also a method of calibrating through the hidden developer menu, available in code ##3646633## (not working on all firmware versions). Hardware Testing → Display → LCD sometimes has RGB Gain sliders available to manually amplify or weaken red, green and blue channels. This is the most powerful tool, but it requires a reference image for comparison.

Eliminating the yellow and blue screen

One of the frequent problems with the Redmi Note 8 Pro is the so-called "yellowness" at the edges of the screen or at the bottom of the display. IPS-If the yellowness seems excessive, try selecting a "Standard" profile in the color scheme settings and moving the temperature slider towards "Cold".

The opposite problem is that you have a lot of blue, which is often in saturated color mode. Blue light is more tiring to your eyes and can disrupt your melatonin production in the evening. You don't have to buy yellow filter protective glass to eliminate this effect, you have to adjust the software settings well, and white balance is a key parameter that affects your perception of shades.

If none of the software methods works and you see obvious color spots (pink or greenish corners), this may indicate physical damage to the matrix or plume, in which case the software calibration of Xiaomi will not work, and you will need to replace the display module.

💡

To check the uniformity of the backlight, download the Screen Test app from the Play Market or open a pure white image to the full screen at maximum brightness, which will help to identify lights or color spots.

Adjusting automatic brightness and sensors

The quality of the image depends not only on the colors, but also on the correct operation of the light sensor. If the automatic brightness is not working correctly, the screen can be too dim during the day or blinding at night. There is a special learning algorithm for calibrating the sensor in the Redmi Note 8 Pro.

To train your smartphone to respond to light correctly, do the following: turn on automatic brightness, then manually set a comfortable level in the current lighting conditions. Repeat this procedure several times in different lights (morning, afternoon, lamp), the system will remember your preferences and adjust the brightness curve.

It is also worth checking for a protective film or glass that can overlap the light sensor located next to the front camera. Dirt or poor-quality glass can distort the sensor readings, causing the screen to behave unpredictable. Regularly wiping the top of the screen with soft cloth helps to avoid this problem.

Third-party calibration applications

If MIUI is not enough, apps from the Google Play Store come to the rescue. One of the most popular tools is Screen Balance or Color Calibrator, which creates a translucent layer on top of the interface that allows you to fine-tune the RGB balance (Red, Green, Blue) for each channel separately.

Using these programs requires caution. They consume extra battery power, as they constantly render the layer on top of other applications. However, for the Xiaomi Redmi Note 8 Pro, this is often the only way to achieve perfect white if the factory calibration has gone into the warm spectrum. You can reduce the blue channel by 5-10% to neutralize the yellowness.

Another powerful tool is apps to create your own color profiles, like TestUFO to check the refresh rate and response of the matrix, or DisplayCAL (requires a PC connection), but for most users, simple ones are available directly on a smartphone.

⚠️ Note: Apps that change the color of the screen may conflict with the system theme or the "Paper" mode. If the interface becomes unreadable after installing such a program, delete the application through Safe Mode or application settings.
