Xiaomi’s smartphone screen is not just a display, but a window into the digital world, on which content perception, eye comfort and even mood depend. Incorrect color reproduction can distort photos, make text unreadable, and long-term use tedious. But few people know that even low-end models of Redmi or POCO allow you to fine-tune the screen to your preferences or standards (for example, sRGB for designers).
The problem is that factory settings are often optimized for the “average user” — with overblown brightness, a cold shade of white, and oversaturated colors. This can be convenient for watching videos in sunny weather, but it’s not at all suitable for reading books in the evening or working with graphics. Fortunately, Xiaomi provides several ways of calibrating, from simple sliders in the menu to hidden engineering settings.
In this article, we will analyze all available methods - from basic to advanced, including tuning through the ADB You'll learn how to achieve natural colors, reduce eye strain, and even extend your lifespan. AMOLED-And if your Xiaomi displays colors incorrectly after the update MIUI — There's a solution here, too.
Why Xiaomi’s screen doesn’t show colors correctly
Color distortion on Xiaomi’s screen is rarely a hardware problem — 90% of the time it’s a result of software tweaks or firmware features.
- 🔧 Factory color profile: MIUI The default is a saturated profile (Vivid), which distorts real shades, which is noticeable when compared to screens of other brands (for example, Samsung or iPhone).
- 🔄 Failures after the update: New versions MIUI can reset user color settings or make changes to profiles (for example, after switching to a user’s color settings). MIUI 14 Many users complained about the “greenish” hue).
Another common problem is the uneven lighting on the AMOLED-screens (for example, on Xiaomi 13 Pro or Redmi) K60). It appears as yellowish spots at low brightness and is associated with the peculiarities of organic LEDs. It can not be completely corrected, but the correct calibration will help reduce the visibility of the defect.
If color distortions have occurred after physical damage (fall, moisture), software calibration will not help, in which case the diagnostics of the display module are required.
Basic screen settings via MIUI menu
To start with, the basics are built-in MIUI tools, which are available on all models, from the Redmi Note 10 to the Xiaomi 14 Ultra, and do not require root rights or special knowledge.
Open the Settings → Display and pay attention to the following parameters:
- 🎨 Color mode: You can choose from three profiles: Vivid – the brightest colors, but unrealistic (suitable for games and videos); Standard – balance between realism and saturation (recommended for most tasks). sRGB is the most accurate profile that meets the standard for professional graphics work (not available on all models).
- 🌞 Color temperature: The slider allows you to shift the white balance towards warm (yellow) or cold (blue) shades. 6500K (white-neutral).
- 👁️ Read Mode: Blue light filter, useful for evening use, you can adjust the schedule or manually turn on.
- ⚡ Adaptive brightness: If the function is not working properly, turn it off and adjust the brightness manually.
Advice AMOLED-To reduce the effect of “burn-in”, set the screen timer for 15-30 seconds and avoid static elements (for example, the navigation bar) at maximum brightness.
Select a color profile (standard or sRGB is recommended)|Turn off adaptive brightness when unstable work|Set the color temperature to 6000–6500K|Activate reading mode at night|Check the Contrast and Saturation settings (if available)-->
On some models (for example, Xiaomi 12T or POCO F5) in the Display menu → Additional settings hide the advanced options:
- 🔍 Color correction – allows you to manually adjust shades of red, green and blue.
- 📊 Gamma curve – affects the distribution of brightness between dark and light areas.
Advanced calibration through the engineering menu
If the built-in MIUI settings are not enough, you can turn to the Engineering Mode, which provides access to low-level display settings, but requires caution - incorrect changes can lead to failures.
To open the engineering menu:
- Open the Phone app.
- Enter the combination: ##36446337## (for newer versions, MIUI may not work - see the alternative method below).
- Select the Display or Screen section.
In the engineering menu, pay attention to the following parameters (names may vary depending on the model):
| Parameter | Description | Recommended value |
|---|---|---|
| White Balance | White balance (regulated RGB intensity) | 255-255-255 (neutral) |
| Gamma Correction | Gamma curve correction (affects contrast) | 2.2 (standard for most displays) |
| Color Temperature | Color temperature in Kelvins | 6500K (daylight) |
| Saturation | Flower saturation | 100% (or lower for natural tones) |
Attention, change of parameters DCI-P3 Coverage or Color Space can lead to incorrect display HDR-If you're not sure, leave the default values.
If the code to log into the engineering menu doesn’t work, try an alternative way:
- Install the MTK Engineering Mode app (for MediaTek processors) or Qualcomm Engineer Mode (for Snapdragon) from Google Play.
- Open it and go to the Hardware Testing → Display section.
What to do if the engineering menu is not opened?
Calibration with ADB (for power users)
If you want maximum customization accuracy (for example, for professional color work), you can use ADB, the Android debugging tool. This method is suitable for models based on Qualcomm Snapdragon (most Xiaomi flagships) and requires a connection to a PC.
Step-by-step:
- Enable USB Debugging in the Developer Settings → About Phone → MIUI Version – Press 7 times, then go back to Additional Settings → For Developers.
- Connect your smartphone to your computer and confirm the debugging permission.
- Open the command line (Windows) or the terminal (macOS/Linux) Enter: adb shell settings put system screen_color_balance [R],[G],[B] where [R], [G], [B] — significance 0 before 255. For example, for neutral white: adb shell settings put system screen_color_balance 255,255,255.
Other useful ADB-calibration:
- 🔹 Set the color temperature (6500K): adb shell settings put system screen_color_temperature 6500
- 🔹 Reset color settings to factory: adb shell settings delete system screen_color_balance
⚠️ Attention, incorrect values in ADB-Before experimenting, write down the current settings with the command: adb shell settings list system | grep screen
Calibration for specific tasks: games, photos, reading
There is no universal screen settings, the optimal settings depend on the use case.
| The challenge | Color profile | Color temperature | Brightness | Additionally. |
|---|---|---|---|---|
| 🎮 Games | Vivid | 6500–7000K | Maximum | Enable Game Turbo in the settings |
| 📸 Photo processing | sRGB or Standard | 6500K | 50–70% | Turn off adaptive brightness |
| 📖 Reading books | Standard | 5000–5500K | 30–40% | Enable Reading Mode + Dark Theme |
| 🎥 Watching movies | Standard or Cinema | 6000–6500K | Auto (or 60–80%) | Insert HDR (if supported) |
For designers and photographers, it is critical that the screen meets the sRGB or DCI-P3 standard. Check the color space coverage in the display settings (on Xiaomi flagships this option is usually available). If it is not, use an external calibrator (for example, Display CAL from Google Play).
⚠️ Attention! AMOLED-In low brightness, you can see "noise" -- random color pixels -- that's normal for organic displays, and calibration won't help. To reduce the effect, raise the brightness to 20 to 30%.
Verification of calibration results
After setting up the screen, it is important to make sure the colors are displayed correctly. Use test images and specialized applications to do this.
List of verification tools:
Pay attention to the following points:
- ☀️ White color: 6500K It should look neutral, without yellow or blue.
If the colors still seem inaccurate after calibration, the problem may be hardware (e.g., a defect in the matrix or display controller).
💡
To objectively assess color, use two devices: your Xiaomi and a reference screen (like a factory calibration monitor). Compare them under the same light.
Frequent problems after calibration and their solution
Even after careful adjustment, the screen can behave unexpectedly, and here are the most common problems and ways to fix them:
- 🔄 Colors are lost after rebooting: This means that the settings of the engineering menu or ADB The solution is to use applications like Tasker to automatically apply commands when you start the system.
If after calibration the screen began to flicker or artifacts appeared (for example, stripes when scrolling), this may indicate:
- Conflict with the MIUI shell (try switching to a standard launcher).
- Incompatible with DC Dimming enabled (turn it off in Settings → Display → Additional).
- Hardware defect (especially relevant for the AMOLED-screens older than 2-3 years).
💡
If after calibration the screen has become worse, you can always return factory settings through ADB or reset the parameters in the engineering menu.
