How to set up a screen on Xiaomi: a complete guide to brightness, colors and hidden features MIUI

The screen of Xiaomi smartphone is not just a display, but a key element of interaction with the device, on which the comfort of use, autonomy and even eye health depends. Many users are limited to basic brightness settings, not knowing that under the hood MIUI There are dozens of parameters that are hidden to fine-tune the image, from calibrating the color profile correctly to turning on the mode. DC Dimming (which reduces screen flicker) – every nuance affects the perception of content.

In this article, we will analyze all available ways to customize the screen on Xiaomi, Redmi and smartphones. POCO, including hidden features that the manufacturer does not advertise:

• 🔦 Optimize brightness and contrast for different lighting conditions (including night time).
• 🎨 Calibrate colors to your preferences or standards sRGB/DCI-P3.
• 👁️ Protect your vision with Reading and Without Blue Light.
• ⚡ Increase battery life by properly adjusting adaptive brightness and screen refresh rate.

We will pay special attention to the problem of screen flickering on the OLED-Xiaomi panels (relevant to Mi 11, Redmi models) K50, POCO F4 And how to fix it through the developer's settings, and how to get the display back to the factory if the calibration experiments didn't go according to plan.

1. Basic screen settings: brightness, adaptive mode and timeout

So let's start with the basics, which are out of the box options that affect everyday smartphone use, and most users are limited to adjusting the brightness slider in the notification curtain, but in the case of a smartphone, you can't do that. MIUI There are more flexible tools.

To open the advanced screen settings:

1. Go to Settings → Display.
2. Slip on the item Brightness (not to be confused with a slider in the curtain!).

Here you will see three key parameters:

• 🌞 Adaptive brightness: automatically adjusts the backlight to ambient lighting. It is recommended to turn on, but only after manual calibration (more on this below).
• 🌙 Dark subject: switches the interface to dark tones, saves battery power on the surface. AMOLED-screens (for example, Xiaomi 13 Pro or Redmi Note 12 Pro)+).
• ⏳ Screen timeout: time to automatically shut down the display, 30 seconds optimal for balance between convenience and energy savings.

An important caveat: if adaptive brightness is not working properly (for example, the screen is too dim in daylight), it should be trained.

1. Turn on adaptive brightness.
2. Manually adjust the brightness slider to the current lighting conditions.
3. Lock and unlock the screen, and the system will remember your preferences.

💡

After the update MIUI Adaptive brightness is lost, reset its settings: go to Settings → Annexes → Application management → Three dots (menu) → Reset application settings → Display.

Color calibration: from sRGB standard to user profiles

The color rendering of the screen is a subjective parameter, but Xiaomi offers both pre-configured profiles and manual calibration.

• 🎮 Gamers (exact transfer of shades in games).
• 📸 Photographers (realistic colors when viewing photos).
• 👨‍💻 Designers (compliant with sRGB standards) DCI-P3).

To change the color profile:

1. Open the Settings → Display → Color mode.
2. Choose one of the options: Standard (sRGB) is the most natural transmission, suitable for most tasks; Saturated - enhanced colors, but less realistic; Custom - manual tweaking (not available on all models).

On flagship models (Xiaomi 14, Redmi) K60 Ultra) Extended Mode available DCI-P3, which extends the color coverage – it is relevant for viewing HDR-content on Netflix or YouTube.

Manual calibration is available on devices with AMOLED-screens (e.g., screens, POCO F5 Pro. For that purpose:

1. Select the User Color Mode.
2. Adjust the sliders Warm/Cold and saturation.
3. Use test images (such as the Lagom LCD test) to check the gray balance.

3. Vision protection regimens: how to reduce eye strain

Long-term use of a smartphone, especially in the dark, can lead to digital eye fatigue. Xiaomi offers two main tools for reducing the load:

1. Reading mode (Settings) → Display. → Read mode: filters blue light, making the picture warmer. You can adjust it: 🌅 Activation time (automatically scheduled or manually). 🔥 Intensity (from weak to strong hue).

Without blue light.

In the models with AMOLED-screens (Xiaomi) 12T, Redmi Note 11 Pro+) Reading mode works more efficiently, since the pixels emit light on their own, rather than filtering it through backlighting, as on the backlight. IPS-matrix.

For maximum protection of vision, it is recommended:

• 🕒 Set automatic turn on reading mode from 21:00 to 7:00.
• 📱 Reduce the brightness to 30-40% dark.
• 🔄 Use a dark theme paired with a reading mode for double effect.

💡

Reading mode on AMOLED-The screen reduces the energy consumption on 10-15% Reduced load on blue subpixels.

Warning for owners POCO X3 Pro and Redmi Note 10:

⚠️ Note: On some devices with IPS-Reading mode can cause yellowness that cannot be removed without turning off the function. If it is critical, use it instead without blue light with minimal intensity.

4. Screen refresh rate: 60 Hz vs 90 Hz vs 120 Hz

Modern Xiaomi smartphones support high screen refresh rates (90Hz, 120Hz, 144Hz), which makes animations smoother but affects battery life.

To change the refresh rate:

1. Go to Settings → Display → Screen refresh rate.
2. Choose one of the available values. On some models (e.g. Xiaomi) 13T) Adaptive frequency is available, which automatically switches between 60 Hz and 120 Hz depending on the content.

Advice for gamers: if you play in PUBG Mobile or Genshin Impact, force 120Hz in the game graphics settings – this will reduce input lag (input delay).

Enable Adaptive Mode (if available)|Install. 90 Hz for everyday tasks|Switch to the switch. 120 Hz for games only|Turn off high frequencies when battery is low (<20%)
