Redmi series smartphones, including the popular 5 model, are known for their budget price segment, where manufacturers often save on the quality of display arrays. Device owners often face the problem of cold shades that go into blue, or, conversely, excessive yellowness, which distorts real colors when viewing photos. Standard factory settings are rarely ideal for each user, so manual calibration becomes a necessary step for comfortable use of the gadget.
The color-rendering process on Xiaomi Redmi 5 does not require superuser rights or device flashing, as the MIUI shell provides enough tools for basic correction. However, there are hidden engineering menus that allow you to change the settings at a deeper level that is not available in the normal interface. It is important to understand that changing these parameters incorrectly can lead to incorrect display of colors, so all actions should be done carefully.
In this article, we will look at all the ways to improve your picture, from simple menu settings to specialized applications. You will learn how to eliminate green or pink, adjust the color temperature to your preferences and check the display for broken pixels. Competent color profile setting can visually improve the quality of the matrix, making the image more natural and pleasing to the eyes.
Standard Color Translation Settings in MIUI
The safest and easiest way to influence the display of colors is to use the built-in features of the MIUI shell. Unlike pure Android, the interface from Xiaomi offers advanced screen management capabilities, which are hidden in the menu of additional settings. First, you need to go to the Settings section, then select the Display or Screen, where the main brightness sliders and timeout are located.
So here we're looking at an option that might be called Color Scheme, Read Mode, or Safe Mode. Depending on the firmware version on your Redmi 5, the interface may be slightly different, but the essence remains the same. By switching between Standard, Saturated, and Contrast, you change the gamut of displays of all the elements of the system. The saturated mode makes the colors brighter, but often unnatural, whereas the standard one tries to get closer to the real shades.
💡
Reading mode on Xiaomi not only yellows the screen, but also reduces the load on the eyes by simulating a paper book, which is useful when reading texts at night.
Special attention should be paid to the Safe Mode or Eye Protection function, which removes the blue component of the spectrum. While it is good for health, constant operation in this mode distorts colors, making the image warm and dull. For quality calibration, it is better to turn off all automatic filters and work with a clean image, adjusting only the basic parameters, this will ensure the most accurate transmission of information when viewing the content.
Using the Engineering Menu for Deep Customization
For more advanced users who don’t have enough standard sliders, there is an engineering menu, a hidden part of the system designed to test hardware and fine-tune display, sound and communication settings. The Xiaomi Redmi 5 is accessible through the standard Phone app, typing special code that opens up access to hidden testing features.
Enter the dialer code ##6484## or ##3646633## to open the CIT (Customer Information Test) menu. Here you need to find the section associated with the display, often called Display or LCM Info. In some versions of MIUI firmware, access to Color Temperature can be limited or hidden, but if the option is available, you can manually change the values of the Red, Green and Blue channels.
⚠️ Warning: Making changes to the engineering menu may cause the display to malfunction.Pick the initial values before any changes so you can get it back to normal.
When you change channel values, try not to jump too fast. The optimal is to change the values by 5-10 units at a time, then check the result. If you see that the white color is green or purple, immediately return the settings back. The engineering menu is a powerful tool, but it requires caution and understanding how color balance works.
What if the code doesn't work?
Application of third-party calibration applications
When system tools are scarce, specialized applications from the Google Play Store come to the rescue, such as Screen Balance or Color Calibrator, which allows you to apply a translucent filter to the screen to compensate for the drawbacks of the matrix, and the principle of their work is to adjust the transparency of red, green and blue channels, which allows you to neutralize the redmi 5 display.
Once you install this app, you'll need to give it permission to display over other windows. This is a critical step, because without this permission, it won't be able to adjust colors in other applications. In the interface, you'll see three sliders that match the primary colors. By moving them, you can get a warmer or cooler shade of white that feels most natural to you.
- 🔴 Red: Regulates the intensity of the red channel, helping to remove excess greens or add heat.
- 🟢 Green: Controls the green channel, often used to correct purple shades.
- 🔵 Blue: Responsible for the blue channel, reducing its value helps to get rid of the “cold” glow of the screen.
In addition, they may not work properly in some games or applications with protected content.However, for everyday use on social networks and the browser, this is a great way to improve the visual experience without risking damage to the system.
Checking the display for defects and broken pixels
Before you start active calibration, you need to make sure that your smartphone matrix is physically healthy. The presence of dead pixels or lights can negate all efforts to adjust colors. On Xiaomi Redmi 5, the check is performed visually by displaying monochromatic images of different colors, which allows you to identify anomalies.
There are several diagnostic methods. You can use the built-in engineering menu by selecting the Color test, which consistently floods the screen with red, green, blue, white and black. Carefully examine the screen surface at maximum brightness. Any dots that do not change color or differ from the general background are defective pixels.
| Type of defect | Description | Possibility of correction |
|---|---|---|
| A stuck pixel | The dot burns with one color all the time. | Partially (software) |
| Dead pixel | Black dot, does not respond to light | No (replacement only) |
| Light. | Bright spots on a black background | No (matrix feature) |
If you find stuck pixels, you can try using recovery apps that change colors quickly in the problem area, a technique known as pixel massage that sometimes helps to restore the stuck subpixels to work, but if the pixel is physically dead, no calibration or software action will help, and the only solution is to replace the display module.
💡
Regular screen check on a monotonous background helps to notice the appearance of new matrix defects in time.
Resetting display settings to factory values
In experiments with colors and engineering menus, it is easy to get confused and confound the settings so that the image becomes unnatural. In such situations, the smartest solution is to completely reset the display parameters, which will return the color profile to the state set by Xiaomi engineers when setting up the device.
You don't have to do a full phone data reset, just go to Settings -> Additional -> Restore and Reset. You can select the Reset Settings option, which is different from Full Reset, which only affects system settings, including Wi-Fi, Bluetooth and, importantly for us, screen settings, without deleting your personal files and apps.
☑️ Checklist before resetting screen settings
Once rebooted, any changes made through the engineering menu or third-party apps (unless they have permanent permission) will be voided, a blank slate from which to start calibrating again using more proven methods, and if the color problem persists even after reset, it is likely to be the hardware or the matrix degradation over time.
Effect of night light mode on color reproduction
Special attention should be paid to the function “Night mode” or “Read mode”, which is actively promoted in modern versions of MIUI. It automatically changes the color temperature of the screen depending on the time of day, making the image more yellow in the evening. For Redmi 5 this is relevant, since the IPS matrix installed in the model, and so can have a cold hue, which in the evening becomes too aggressive.
This mode is set up in the same Display menu, and you can set a schedule for, say, sunset to dawn, or set a fixed time, and you can set the intensity to choose how strong the yellow effect is going to be. For accurate color calibration, it's best to turn it off when you're working with graphics, because it's a big distortion of the color gamut.
Using automatic brightness in conjunction with night mode can create strange effects when the screen turns yellow and blue depending on the lighting. It is recommended to adjust these parameters manually to make the screen behavior predictable. Understanding the operation of these filters will help you avoid the false impression that the screen is "glutting" or incorrectly calibrated.
