Xiaomi Display Calibration: A Detailed Guide to Customize the Screen Accurately

The screen of the Xiaomi smartphone is not just a panel for displaying information, but a key element on which the comfort of using the device depends. AMOLED- or IPS-Displays can display distorted colors, incorrect white balance, or inflated temperature if not calibrated. In this article, we will discuss how to customize the display on any Xiaomi smartphone, from the budget Redmi to the flagship Mi and the newest. POCO, — The picture is as natural as possible, and the eyes are less tired.

Many users mistakenly believe that the factory settings are optimal. However, manufacturers often overstate saturation and contrast to make the device look brighter in the store. In real life, this leads to unrealistic colors in the photo, eye fatigue when reading and even distortion of shades in professional applications. Fortunately, Xiaomi provides flexible tools for manual calibration - you just need to know where to look for them and how to use them correctly.

In this instruction you will find:

• 🔍 Step-by-step calibration methods for different Xiaomi models (including hidden settings)
• 🎨 Explanation of technical terms - what is sRGB, DCI-P3 and how they affect the image
• ⚠️ Common mistakes that spoil calibration and how to avoid them
• 📱 Comparison of factory and user color profiles

1. Calibration preparation: What to do before setting up the screen

Before you start changing the display settings, it is important to make sure that external factors do not distort the perception of the image.

Make sure the screen is set to 50-70% | Turn off adaptive brightness in settings |Put your smartphone in a room with neutral lighting (no direct sun) |Put the battery at least 30% |Remove the protective film or glass if it distorts the colors-->

Pay special attention to lighting. Warm light bulbs (2700K) will add yellowness, cold (6500K) will add blue. Ideally use daylight or lamps with a color temperature of 4000-5000K. Also check if the system is not on reading mode (Settings → Display → Reading Mode) - it adds a yellow filter that will distort the calibration results.

If you are using Xiaomi with AMOLED-screen (for example, Xiaomi 13 Pro or POCO F5 Pro, note that such displays are prone to pixel burnout during prolonged display of static elements. Before calibration, it is recommended to run a test for broken pixels (for example, through the Screen Test application) to ensure that the matrix is healthy.

⚠️ Note: If your smartphone has recently fallen or been repaired, calibration may not give the expected result due to physical damage to the matrix or plume. In this case, first check the display for artifacts (strips, flickers) in the service center.

Standard display settings in MIUI: what can be changed without root

MIUI firmware offers basic screen customization tools that are available without additional permissions. To open them, go to:

Settings → Display → Additional settings → Colors

Here you will find three main parameters:

• 🌈 Color profile: Saturated (factory), Standard (close to sRGB), User (manual setting)
• 🔄 Color temperature: slider from Cold (blue) to Warm (yellow)
• 📊 Contrast: not available on all models, adjusts the difference between the darkest and lightest areas

For most tasks, you just need to choose a Standard Profile, which is closest to natural colors. However, if you want precise calibration, choose a Custom Slider and manually adjust the Red, Green and Blue sliders. On AMOLED screens (such as Xiaomi 12T), these settings affect more than IPS (Redmi Note 11).

💡

To check color accuracy, use test images with known color profiles (for example, Lagom LCD Test). Pay special attention to gray gradients - they should be smooth, without color bias.

3. Hidden calibration settings: how to access the engineering menu

If standard MIUI options aren’t enough, you can use the Engineering Mode, which offers advanced display options, which works on most Xiaomi models, but requires caution – incorrect settings can degrade the image.

To open the engineering menu:

1. Open the Phone app.
2. Enter the combination: ##3644633## (may be different for some models).
3. Select the Display or Screen section.

In the engineering menu you will find:

• 🔧 Fine-tuning RGB: fine-tuning the intensity of each color channel
• 📏 Gamma correction: correction of the gamma curve (affects contrast in medium tones)
• 🔄 White balance: White balance in step 100K (from 2000K before 10000K)

⚠️ Warning: Changes to the engineering menu are not reset after rebooting. If after calibration the screen becomes worse (for example, a green tint appeared), return all sliders to position 0 or reset the display settings through Settings → System system → Resetting settings → Resetting display settings.

4. Calibration with third-party applications: top-3 tool

If MIUI is not enough, you can use specialized applications that offer more flexible settings, color blindness tests, and the ability to save multiple profiles.

1. Display Calibration (free, rootless) ✅ Color temperature and gamma curve tests ✅ Setting up RGB-balance ❌ No support. HDR-calibration
2. Screen Balance (paid, $2.99) ✅ Keeping multiple profiles (e.g., “Day” and “Night") ✅ Calibration for specific applications (for example, for Lightroom) ❌ Demands. ADB-full access

Colorimeter

• ✅ Works with external colorimeters (e.g. X-Rite) i1Display Pro)
• ✅ Support for profiles DCI-P3 Adobe RGB
• ❌ A complex interface, requires knowledge in colorimetry

For most users, Display Calibration is enough. If you need professional calibration (for example, for photo processing), consider buying a hardware colorimeter. These devices start at $100, but they provide accuracy unachievable by software methods.

5 Calibration for specific tasks: games, photos, reading

The best screen settings depend on how you use your smartphone, and below are recommendations for different scenarios:

🎮 For gamers (POCO F5, Black Shark 5)

• 🔥 Color profile: Saturated (increases contrast for better detail visibility)
• 🎯 Colour temperature: 6,000–6500K (Cold tones reduce eye fatigue during long sessions)
• ⚡ Update frequency: 120 Hz or 144 Hz (if supported)

📸 For photographers (Xiaomi 13 Pro, Redmi Note 12 Pro)+)

• 🎨 Color profile: Standard or sRGB (maximum accurate color reproduction)
• 🔍 Brightness: 40-50% (to avoid lighting when editing photos)
• 📱 HDR: On (if the screen supports) HDR10+)

📖 Reading and working with text (Redmi) A2+, POCO M5)

• 🌓 Colour temperature: 4,000–4500K (Warm tones reduce the load on the eyes)
• 📄 Reading Mode: On (Blue Light Filter)
• 🔎 Contrast: 30-40% (reduces font sharpness)

💡

For games and videos, it is better to use cold color temperature (6000K+), and for reading and working - warm temperature (4000-5000K).

Typical calibration errors and how to avoid them

Even experienced users sometimes make mistakes that spoil the calibration result, and here are the most common mistakes and ways to correct them:

• 🚫 Calibration at maximum brightness: At 100% brightness, the colors look different than at 50%. Adjust the screen to the brightness level you use most often.
• 🚫 Ignoring ambient light: Colors are perceived differently in daylight and artificial light. Calibrate the screen in the conditions in which you use your smartphone.
• 🚫 Too high saturation: Excessively saturated colors look unnatural and fatigue your eyes faster.Use test images (e.g. Photodon) to check balance.
• 🚫 Inconsistency with other devices: If you work with photos on multiple devices (smartphone, monitor, tablet), their color profiles must match. Use sRGB as a universal standard.

Critical error: Automatic image enhancers (such as AI Color Enhance in some firmware) are used to artificially overstate contrast and saturation, making it impossible to calibrate accurately.

⚠️ Note: On smartphones with AMOLED-screens (e.g. Xiaomi) 12S Ultra) too low brightness (<30%) may flicker (PWM-effect, which is bad for the eyes. If you notice a pulsation of the screen, increase the brightness or turn on the mode DC Dimming in the Developer Settings.

Verification of calibration results: tests and tools

After setting up the screen, it is important to make sure that the colors are displayed correctly.

• 🎯 Gradient test: Checks the smoothness of transitions between colors. A properly calibrated screen should not have stripes or jumps. Example: Lagom Gradient Test
• 🔍 Gray test: Shows if there is a color shift in neutral tones.Gray squares should look the same, without shades of blue or red. Example: Lagom Greyscale Test
• 📊 Color Range Test: Checks what colors your screen can display (such as sRGB or sRGB) DCI-P3). Example: Display Calibration

If you find problems after the tests (for example, a green hue on a gray background), go back to the settings and adjust the white balance or the white balance. RGB-on the AMOLED-Check if there are any burnt-out pixels on the screens, as they can distort the perception of colors in certain areas.

💡

To make an objective assessment, use a camera from another device. Take a picture of your Xiaomi white screen and check if there is a color shift in the photo, which will help identify hidden distortions.
