Screen calibration on Xiaomi: a detailed guide to adjusting colors and brightness

The screen of Xiaomi smartphone is not just a display, but a key element of interaction with the device. AMOLED-Matrixes in Redmi Note 13 Pro+ Xiaomi 14 Ultra can display distorted colors if not tuned correctly, problems like excessive blue, dull shades or blurred gradients are often solved by simple calibration, a procedure many users do not even know about.

In this article, we’ll explore how to calibrate the screen on any Xiaomi smartphone (including models on MIUI 14/15 and older versions), why factory settings are not always optimal, and what tools will help achieve perfect color reproduction. You’ll learn how to fix unnatural skin tones, over-lit white or dull black — without root rights and third-party firmware.

Why do you need to calibrate the screen on Xiaomi?

Smartphone manufacturers (including Xiaomi) often customize displays to the “average” user, which means:

• 🔵 Higher color temperature (screens look “cold”) for better readability in the sun.
• 🟢 Increased saturation – to make the picture seem “juicier” in the store.
• 🟡 Nonlinear gamma (incorrect ratio of brightness of dark and light tones).

As a result, gallery photos can look different than other devices, and videos can lose detail in the shadows. AMOLED-screens (Xiaomi) 13T, POCO F5), where each pixel is individually illuminated, and the slightest calibration errors are striking.

Calibration solves these problems by bringing color reproduction closer to sRGB or DCIP3, which is what professional photographers and film studios use, but it's important to understand that setting "to yourself" and setting "to standards" are different things. One depends on your preferences, the other depends on the technical requirements.

Preparation for calibration: what you need to know

Before you start setting up, check:

1. MIUI Version: Setup Path → About Phone → MIUI Version. Instructions for MIUI 12 and MIUI 15 may differ.
2. Screen type: AMOLED (deep black, high contrast) or IPS (more natural colors, but backlit) can be found in the characteristics of the model or through the AIDA64 application.
3. Current color profile: Xiaomi’s default is often “saturated” or “auto”, which distorts the real shades.

Also prepare:

• 📱 Test images with a known color palette (e.g. Lagom) LCD Test).
• 🔍 Screen Testing (Screen Test, Display Tester).
• 📝 Write down the current settings to return them if the result doesn't like.

Record the current color settings

⚠️ Note: If your Xiaomi supports HDR (For example, Xiaomi 13 Pro or Black Shark 5, turn it off in the screen settings before calibrating. HDR Uses an extended color range, which will distort the test results.

Method 1: Calibration through standard MIUI settings

The easiest method is to use the built-in MIUI tools, which are suitable for most models, including the Redmi Note 12, POCO X5 and flagships like Xiaomi 14.

Steps:

1. Open the Settings → Display.
2. Choose the Color Scheme (or Color Style in older versions).
3. Try pre-profiles: Saturated - bright but unnatural colors; Standard - closer to sRGB (recommended for most tasks); Gentle - warm colors, less eye strain.

Customized

In user mode, you can adjust:

💡 Tip: Use gradient test images to assess the smoothness of transitions. If you see bands on the screen, reduce contrast.

💡

To check the color rendering, open the Photo Finish Calibration website in your browser - there are special tests to adjust the gamut and white balance.

Method 2: Applications for accurate calibration

If built-in MIUI tools aren't enough, use third-party apps that offer advanced tests and more flexible settings.

Top.-3 calibration:

• 📊 Screen Balance – analyzes color temperature and offers optimal values.
• 🎨 Color Calibration – Manual setting RGB-channels with preliminary testing.
• 🔍 Display Tester – Checks the screen for broken pixels, gradients and color distortions.

Instructions for Screen Balance:

1. Download the app from Google Play.
2. Run a white balance test and the program will show the current color temperature.
3. Follow the tips to adjust the settings manually or automatically.
4. Apply the changes through the MIUI screen settings.

⚠️ Note: Some apps (e.g. Color Calibration) require permission to overlay over other windows. → Annexes → Special access → Overlay.

Method 3: Calibration through the engineering menu (for advanced)

The engineering menu (#36446337##) allows fine-tuning screen settings, but requires caution, a method suitable for power users, as incorrect values can degrade image quality.

How to open and use:

1. Enter the code ##36446337## in the Phone app.
2. Go to the Display or Screen section.
3. Find the parameters: Color Temperature (color temperature 1 to 100), Gamma Correction (color temperature) (color temperature), RGB Balance (red/green/blue balance).

Make changes one by one by checking the result on the test images.

📌 Example of values AMOLED-Xiaomi screen 12T:

Color Temperature: 65 (Neutral White)


Gamma: 2.2 (standard for most content)




RGB Balance: R=255, G=250, B=245 (light decrease in blue)

⚠️ Warning: Changes to the engineering menu are not reset after rebooting. If the screen starts to look worse, return the values to the factory or reset the settings through Settings → System system → Resetting settings (select "Reset screen settings").

Problems after calibration and their solutions

Even after careful adjustment, problems can arise, and here are the most common ways to fix them:

If the problems persist, try:

• 🔄 Reset the screen settings to factory.
• 📥 Update the firmware (sometimes color reproduction bugs are fixed in new versions) MIUI).
• 🛠️ Contact the service center - a physical defect of the matrix is possible.

Calibration for specific tasks: games, photography, reading

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

For games (MOBA, shooters):

• 🎮 Profile: "Saturated" (for better visibility of details).
• 🔥 Brightness: 80-100% (to avoid missing the enemy in the shadows).
• 🎯 Color temperature: 7000K (Cold shade reduces eye fatigue during long sessions).

For photo processing (Lightroom, Snapseed):

• 📸 Profile: "Standard" or "sRGB" (for accurate color reproduction).
• 🔍 Contrast: 50% (to avoid losing detail in shadows and lights).
• 🎨 Saturation: 40% (natural colors without distortion).

For reading and working with the text:

• 📖 Profile: "Tender" or "Warm" (less strains the eyes).
• 🌙 Brightness: 30-50% (depending on the lighting).
• 🔄 Adaptive brightness: turn on (for automatic adjustment).

💡

For professional color work (design, photography) use an external calibrator, such as the X-Rite i1Display Pro. A smartphone cannot provide 100% accuracy without specialized equipment.
