Xiaomi screen calibration: how to adjust colors, brightness and contrast

The screen of a smartphone is not just a display, but a major window into the digital world. Its quality depends on how comfortable you will be perceive content, work with applications or just flip through the tape of social networks. AMOLED-It's a very dark screen, and it's very rich in color, but even these sometimes require fine tuning, and if you calibrate it incorrectly, it can cause the image to be too cold, over-lit white, or dim in sunny weather.

Many users do not even know that their Redmi Note 12 or Poco X5 And it's more than that, because factory settings are often focused on the "average consumer" rather than on individual preferences, MIUI It offers flexible tools for manual and automatic calibration, and in this article we will explore all available methods, from basic brightness settings to professional color correction using hidden engineering menus.

You will learn how to fix typical screen problems – for example, when white gives a greenish or blue tint on models with a high-end screen. E4 AMOLED (It is also common in Xiaomi 13 Pro and Mix Fold 3, or why it becomes too dark indoors when it is automatically bright. DCI-P3 for a wider color range or calibrate the screen for professional photo work.

Why do you need to calibrate the screen on Xiaomi?

Even the most expensive Xiaomi smartphones with factory settings can show imperfect color reproduction. Here are the main reasons why you should start calibrating:

• 🎨 Unnatural colors: the skin in the photo looks too red, the sky is unnaturally blue, and green shades “clog” details.
• 🌡️ Improper white balance: the screen gives a cold (blueish) or warm (yellowish) shade, which tires the eyes.
• 🔦 Brightness problems: automatic adjustment works with failures - in sunny weather nothing is visible, and in the evening the screen is blinding.
• 📊 Non-compliance with standards: it is important for designers and photographers to support sRGB or DCI-P3, which may be deactivated by default.

For example, the owners of Xiaomi 12T Pro often complain of excessive color saturation in Vivid mode, and the Redmi Note 11 Pro+ In the dark, you get gray instead of deep black, and these problems are solved by calibration.

In addition, the wrong screen settings can affect battery life. Too high brightness or on mode. HDR10+ In unnecessary applications, the battery is drained 15-20% faster, calibration helps to find a balance between picture quality and energy efficiency.

⚠️ Note: On smartphones with LCD-screens (e.g. Redmi) 10C POCO M5) There's limited calibration, and you can only adjust the white balance and the brightness, and you can only adjust the deep color correction. AMOLED-display.

Calibration Preparation: What to Do in Advance

Before you start settings, follow a few important steps to avoid typical errors and achieve better results:

1. Update. MIUI New firmware often improves color correction algorithms. You can check the relevance in Settings. → The phone. → Updating the system.
2. Charge your phone by at least 50%. Some calibration modes (like pixel burnout testing) consume a lot of power.
3. Use a neutral environment. Calibration is best done in daylight or under a lamp with a color temperature of 4000–5000K (not warm yellow or cold blue light).
4. Turn off "Adaptive Brightness" in Settings → Display. → Brightness: Automatic adjustment can distort color perception.

If you plan to use professional tools (like the Display Calibration app or Screen Balance app), install them in advance from Google Play. i1Display Pro, but this is only relevant for designers and photographers.

To check the current screen parameters, you can use free tests:

• 📱 Display Tester – Check for broken pixels, gradients and color transitions.
• 🎨 Screen Test – analysis of white and color coverage.

⚠️ Note: If your Xiaomi has recently fallen or been repaired, there may be hardware problems with the screen (such as damage to the plume or matrix.

Basic calibration through settings MIUI

Let’s start with the simplest: built-in tools. MIUI. They are available on all Xiaomi smartphones, regardless of the model, and allow you to quickly improve the picture without third-party applications.

Open the Settings. → Display. Here you're interested in the following parameters:

• 🌈 Color scheme: Choose Saturated (for bright colors), Original (for natural shades) or sRGB (for professional work). 13/14 The series is also available in mode. DCI-P3.
• 🔄 Color temperature: Move the slider towards Warm (less blue light) or Cold (more natural white).The optimal value for most is 4500–5000K.
• 📱 Screen resolution: on flagships (e.g. Xiaomi) 12S Ultra can be chosen between FHD+ and QHD+. Higher resolution gives clarity, but reduces battery life.
• 🔍 Reading: Enable Vision Protection mode to reduce blue light in the evening. Set up a schedule or manually activate.

For models with AMOLED-screens (e.g. Poco) F5 Pro or Redmi K60) Additional options available:

• 🖤 Deep Black: Include Dark Theme and AMOLED black.
• 🔄 Upgrade frequency: Choose 120Hz for smoothness or 60Hz for charge savings.Adaptive mode is available on some models.

When you change the settings, check the result on the test images, for example, open this page in your browser and rate:

• Gray transitions (should be smooth, without stripes).
• Color gradients (no sharp jumps in shades).
• White balance (the background looks neutral, without shades).

💡

If the color changes are too dull, try turning Vivid mode into Settings. → Display. → Color scheme. It artificially enhances saturation, but it can distort the shades in photos.

Advanced calibration through the engineering menu

For those who have standard settings MIUI Not enough, there's a hidden engineering menu that allows you to fine-tune white balance, gamut, and even calibrate the light sensor.

To open the engineering menu:

1. Open the Phone app.
2. Enter the combination: ##3644633##
3. Choose. CIT (or Engineering Mode on Global Firmware).

In the engineering menu, go to the Display (or Screen) section, where you can set the following settings:

Use test patterns to fine-tune your settings, such as opening this page in your browser and adjusting the settings until the gray squares are indistinguishable from the background.

⚠️ Warning: Changes to the engineering menu are not reset after rebooting. If you make a mistake with the settings, return the values to the factory or reset through Settings → System system → Resetting settings → Reset all settings (without deleting data).

Calibration with third-party applications

If Xiaomi’s built-in tools aren’t enough, third-party apps come to the rescue, offering more flexible settings, support for color profiles, and even the ability to create your own. ICC-color-rendering.

Top.-3 calibration:

• 📱 Display Calibration (Free, Google Play): Customize white balance RGB. Gamma and contrast correction, color blindness tests and gradient testing.
• 🎨 Screen Balance (paid version, Google Play): Support for sRGB profiles, Adobe RGB, DCI-P3. Automatic calibration from the reference color photograph, saving custom presets.
• 🔍 Colorimeter Calibration (for professionals, requires a colorimeter): Creation ICC-Profiles for exact compliance with standards Calibration according to Delta E standards < 2 Export profiles for use in Photoshop or Lightroom.

For the basic setup, Display Calibration is fine.

1. Start the app and select Manual Calibration.
2. Follow the on-screen instructions, adjusting the Red, Green, Blue sliders until the grey squares merge with the background.
3. Save the profile and apply it.

For professional work (for example, if you edit a photo on Xiaomi 13 Ultra), it is better to use Screen Balance with a colorimeter.

1. Connect the colorimeter to the phone through OTG-adapter.
2. Run the calibration in the app by following the hints.
3. Select a target profile (e.g. sRGB for web graphics or DCI-P3 video).
4. Save and activate the profile.

⚠️ Note: Some applications (e.g. Colorimeter Calibration) require root rights for deep calibration, without which they are limited. MIUI User profiles may be reset.

💡

For most users, basic calibration through Display Calibration is enough, ICC-Profiles only required by designers, photographers and videographers.

Solving typical Xiaomi screen issues

Even after calibration, there may be artifacts or problems on the screen, and we'll look at some of the most common problems and how to fix them.

1. Green or blue hue on a white background

Frequent problem at Xiaomi 12/13 series E4 AMOLED. Decisions:

• 🔧 Open the engineering menu (#3644633##) and reduce the Blue value in White Balance by 5-10 units.
• 📱 Enable sRGB mode in Settings → Display. → Color scheme.
• 🔄 If the problem persists, reset the screen settings through Settings. → System system → Resetting settings → Resetting display settings.

2. Automatic brightness is not working correctly

Is the screen too dark during the day or too bright at night? The problem is the light sensor.

• 🧹 Clean the sensor area (usually near the front camera) of dust and protective film.
• 📊 Calibrate the sensor in the engineering menu: CIT → Single Item Test → Light Sensor. Follow the instructions on the screen.
• 🔄 Turn off and turn on Adaptive Brightness again in the settings.

3. burn-out of pixels (burn-in) on AMOLED

Permanent interface elements (such as the navigation bar) can be imprinted on the screen.

• 🔄 Enable Hiding the Cutout in Settings → Display. → Full screen mode (hiding the status bar).
• 🎨 Use dark wallpaper and themes.
• 🔧 Run the burnout test in Display Tester and activate Pixel Refresh if you find a problem (available on some models in the engineering menu).

4. Screen flickering (PWM-sewing)

Some Xiaomis (such as Redmi) K50) It's very flickering at low brightness. PWM (pulse-width modulation. Solutions:

• 🔦 Increase the brightness to 30 to 40 percent, and at this level, the flicker usually disappears.
• 🔧 Turn it on. DC Dimming in the engineering menu (if available) this function replaces PWM direct current, but may impair color reproduction.
• 📱 Update the firmware - in new versions MIUI They often improve algorithms. PWM.
