Contrast settings on Xiaomi phone: from basic settings to hidden features MIUI

Xiaomi’s smartphone screen is not just a display, but a window into the digital world, on which the comfort of the device depends. Contrast plays a key role in the perception of the image: too low makes the text blurry, and high levels can tire the eyes in the dark. In this article, we will discuss all the ways to adjust contrast on Xiaomi, Redmi and other phones. POCO — from standard parameters in MIUI Up to Hidden Features for Advanced Users.

It’s important to understand that contrast directly affects text readability, color perception, and even battery life (at maximum values, battery consumption increases).We’ll look not only at manual settings, but also at automatic modes that adapt the screen to lighting. And for the owners. AMOLED-Displays have prepared separate recommendations - such screens require a special approach.

If you notice that your Xiaomi colors have become faded or too saturated, and text is difficult to read in the bright sun, this guide will help you return to a comfortable display.

What is contrast and why you need to adjust it

The contrast of the screen determines the difference between the brightest and darkest shades that a display can reproduce. The higher the contrast, the deeper the black and the brighter the white. AMOLED-screens (for example, Xiaomi 13 Pro or Redmi) K60 Ultra) contrast is initially higher than on IPS-matrix (POCO X5, Redmi Note 12).

Why is this important for the user:

• 📱 Readability: When contrast is low, letters stick together with the background, especially in sunny weather.
• 🎨 Image quality: photos and videos look more voluminous and detailed.
• 👁️ Eye comfort: the right setup reduces fatigue with prolonged use.
• 🔋 Energy consumption: by AMOLED-High contrast screens can reduce battery life.

Standard settings MIUI They often offer "average" contrast values that are not for everyone, for example, in dark rooms you may need to lower the parameter to reduce the strain on the eyes, and in the street you may need to increase for better visibility.

⚠️ Attention: On phones with AMOLED-displays (Xiaomi) 12T, Redmi K50 Pro: Long-term use of maximum contrast can cause burn-in pixels, especially static interface elements (navigation panels, icons).

Basic contrast setting through the menu MIUI

The easiest way to change contrast is to use built-in settings. MIUI. This method is suitable for all modern Xiaomi models, including the Redmi Note 11, POCO F5 and the flagship series:

1. Open the Settings app (cog icon).
2. Go to the Display section.
3. Select Color Scheme or Color Style (the name may vary depending on the version). MIUI).
4. Here you will see the slider Contrast or preliminary profiles (Standard, Saturated, Soft).
5. Move the slider around as you watch the changes on the screen, and the best value is when the text is clear and the colors look natural.

In some firmware (for example, MIUI 14 for Xiaomi 13) instead of the slider offered ready-made modes:

• 🌞 Bright: Increased contrast for outdoor use.
• 🌙 Dark: reduced contrast for night time.
• 🎨 Rich: Enhanced colors (suitable for watching media).

If you're in your version MIUI There's no separate contrast slider, try changing the color temperature (in the same section of the Display), cold (blueish) visually increase contrast, and warm (yellowish) reduce contrast.

Open the Settings → Display

Check the current color profile

Evaluate the comfort of displaying the text

Make sure the adaptive brightness is turned off (if manual control is needed)-->

Fine tuning through “Eye Mode” and adaptive functions

MIUI It offers several tools to automatically adjust contrast to lighting, which are especially useful if you move between rooms with different levels of light.

1. Reading mode (or "Eye Mode")

This mode not only filters blue light, but also automatically adjusts contrast to read comfortably.

1. Go to Settings → Display → Reading Mode.
2. Turn on the switch and set the schedule (for example, from 21:00 to 7:00).
3. Activate the option of Avtobrightness in read mode – this will allow the system to dynamically adjust the contrast.

2. Adaptive brightness

It analyzes ambient lighting and automatically adjusts not only brightness, but also contrast, so that it works correctly.

• 📱 Include adaptive brightness in Settings → Display. → Adaptive brightness.
• 🔄 Calibrate it manually: in a dark room, reduce the brightness to a comfortable level, then repeat in a brightly lit room.
• 🚫 Turn it off if you notice that the screen is too dark or, conversely, becomes too bright for no reason.

3. Super Wallpaper (for the AMOLED)

On the phones with AMOLED-screens (Xiaomi) 12S Ultra, Redmi K40 Pro) Super Wallpaper wallpaper automatically adjusts contrast according to the time of day, for example, night wallpaper will be darker and less contrasting than day wallpapers.

Constantly.

Only in the daytime.

Only at night.

Never turn it on.

Depends on the situation.-->

Hidden contrast settings through the engineering menu

For advanced users who lacked standard tools MIUI, You can fine-tune it through the engineering menu, and this method requires caution, because incorrect changes can cause display failures.

To open the engineering menu:

1. Open the Phone app.
2. Enter ##36446337## (for MediaTek) or #4636## (for Qualcomm).
3. Select the Hardware Testing option → Display.

In this menu you will find the parameters:

• 🔧 Contrast – manual contrast setting (values from 0 to 255).
• 🎛️ Gamma Correction - Gamma curve adjustment (affects brightness distribution).
• 🖥️ Color Temperature – Accurate Color Temperature setting (in Kelvins).

⚠️ Note: Changes to the engineering menu are not saved after the reboot unless recorded through special commands. ADB. Also in some models (POCO F3, Redmi 10: Engineering menus can be blocked by the manufacturer.

To maintain the configuration (on a permanent basis) will need to use ADB:

adb shell settings put system screen_contrast_value 180

Where 180 is the desired contrast value (select experimentally).

Features of settings for AMOLED and IPS-Xiaomi screens

Display technology has a significant impact on how contrast is perceived, and let’s look at the key differences and recommendations for each type:

For AMOLED-screens:

• 🌑 Use dark themes and wallpaper – this not only saves charge, but also reduces the load on the pixels.
• 🔄 Enable Auto Brightness with Adaptive Contrast (in Settings) → Display. → Additionally).
• 🚫 Avoid static elements (e.g., displaying time on a locked screen).

For IPS-screen:

• ☀️ Increase the contrast on 10-15% above the "comfortable" level, which compensates for the low native contrast of the matrix.
• 🎨 Use a media rich and standard text profile.
• 🔦 In sunny weather, turn on the Sunlight Amplifier mode (if available).

💡

On the phones with AMOLED (For example, Xiaomi 13 Ultra, turn on the option DC Dimming in the display settings. This will reduce the flickering of the screen at low brightness, which is especially important for sensitive eyes.

Contrast adjustment for people with visual characteristics

MIUI It offers special modes for users with color blindness or other visual features, which can be combined with manual contrast adjustment for maximum comfort.

1. Color correction (for colorblind people)

To activate:

1. Go to Settings → Special Options → Color correction.
2. Choose the type of colorblindness: Protanopia, Deuteranopia or Tritanopia.
3. Adjust the intensity of the correction.

2. Increased contrast of text

To improve readability:

• 🔤 Include High Text Contrast in Special Opportunities → Visibility.
• 📖 Use system fonts with bold marking (Settings) → Display. → Type size and style).
• 🌓 Activate the Inversion of Colors (useful for photophobia).

Increase mode (magnification)

If the text is difficult to read even in high contrast:

1. Include Increase in Special Opportunities → Visibility.
2. Set up a scale factor (up to 8)×).
3. Use color filters to improve visibility.

⚠️ Caution: Color Inversion mode may conflict with some applications (e.g. banking) and check the performance of critical services before using it.

Contrast Problems and Their Solutions

Sometimes users are faced with situations where contrast is not behaving correctly: spontaneously changes, too low even at the maximum or, conversely, is not regulated.
