Modern smartphones Xiaomi and Redmi are equipped with some of the best AMOLED and IPS matrices on the market, but the factory settings are not always ideal for each user. Often after purchase, the owner faces excessive color saturation, incorrect operation of automatic brightness or insufficient smoothness of the interface, which significantly affects the visual experience. Competent calibration and adaptation of display parameters to your preferences allow you to unlock the potential of the device, reduce eye load and even extend battery life.
The optimization process does not require root rights or complex third-party software, as the MIUI shell and the new HyperOS provide extensive tools for this. In this guide, we will detail all hidden and explicit screen settings, explain the difference between color profiles and help eliminate typical sensor problems.
Basic brightness and adaptability setting
The first parameter that a user encounters is the matrix backlight level. The standard slider in the notification curtain is just the tip of the iceberg. For fine adjustment, you need to go to the Settings menu → Screen → Brightness and Color Level. Here lies a key feature that many people ignore: adaptive adjustment. If it's turned off, the phone won't respond to changes in ambient lighting, forcing you to manually spin the slider constantly.
But even the adaptability that's on can be incorrect if the light sensor has memorized the wrong values. The system is trained to your preferences, but it can be accelerated or reset. If the screen is too dim in the dark or too bright in dim lights, try manually setting the desired level in the current conditions several times in a row. The automatic brightness algorithm should adjust to your actions.
- 🌞 Enable the option "Adaptive adjustment" for automatic operation of the sensor.
- 🌙 Activate Read Mode in screen settings to reduce blue spectrum.
- 🔆 Use advanced settings to calibrate minimum and maximum brightness thresholds.
⚠️ Note: When using the function "Reduce flickering" (DC Dimming on AMOLED You can see a slight shift in color reproduction or noise at low brightness levels in screens, and that's a physical feature of the technology, not a matrix failure.
Special attention should be paid to the function of reducing flicker. On many Xiaomi models with a OLED-The displays use pulse-width modulation (PWM) to adjust brightness, which can cause eye fatigue in sensitive users. DC Dimming (or "Anti-Stroboscope") changes the way backlight works, making the glow more stable, albeit at the expense of slightly less accurate colors at a minimum.
Color gamut and temperature regime
Xiaomi's factory screen calibration is often focused on the "window" image: colors are bright, rich, but far from reality. To work with photos, watch movies or just for natural shades, you need to change the color profile. This option is located along the way Settings → Screen → Color scheme. By default, it often has "saturated" or "Vivid", which makes the image acidic.
To achieve maximum color accuracy close to the sRGB standard, switch to the "Standard" or "Classic" profile. In this mode, the unnatural yellowness of white objects or their bluish hue disappears. More advanced users can use manual color wheel settings, where you can separately twist the shade of red, green and blue channels, achieving the perfect white balance.
- 🎨 Select a “Standard” profile for realistic colors.
- 🌡️ Adjust the color temperature with a slider from cold to warm.
- 🖼️ Use the Professional mode for accurate calibration for design tasks.
Temperature is another important parameter: Cold shades (blueish) are invigorating and brighter, but tire the eyes in the evening; warm shades (yellowish) are more pleasant for long reading and night use; and Eye Comfort mode, which automatically shifts the balance to a warm spectrum on a schedule or at sunset, blocking harmful blue light.
💡
Before changing the color settings, allow the screen to warm up 5-10 minutes after turning on, as the cold matrix can display colors with distortions.
Frequency of updates and smoothness of the interface
One of the main features of modern Xiaomi smartphones is a high refresh rate of the screen - 90 Hz, 120 Hz and even 144 Hz. However, simply having a high hertz does not guarantee smoothness. In the Settings menu → Screen → Update frequency, three modes are often available: Standard (60 Hz), Prefer High and Default. Choosing the right mode directly affects the smoothness of scrolling tape and animations.
Default mode is the smartest: the system itself increases the hertz in supported applications (for example, in the browser or settings) and reduces to 60 Hz when watching video or static image to save energy. Forced maximum setting ("prefer high") can lead to faster battery discharge, as some applications are not optimized for this mode and can twitch.
| Mode of work | Frequency (Hz) | Impact on the battery | Recommendation |
|---|---|---|---|
| Standard. | 60 Hz | Minimum | To save charge |
| By default. | Auto (60-120) | Average. | Optimal balance |
| Maximum | 120 Hz (continuing) | High. | For games and maximum smoothness |
| Adaptive | Dynamic. | Low/Mediocre | For LTPO screens |
Owners of flagship models with LTPO-matrixes may notice that the refresh rate changes dynamically from 1 to 120 Hz. This technology allows the screen to almost “freeze” when viewing photos, consuming minimal energy, and instantly accelerate when touching. It is important to understand that not all games support high frequencies, and in such cases the system can forcefully limit FPS to avoid overheating the processor.
Why aren’t there 120Hz in some games?
Font size, scale and interface elements
The comfort of perceiving information depends not only on the quality of the matrix, but also on how the content is located on it. Xiaomi allows you to flexibly adjust the size of the system font and interface elements independently of each other, this is especially true for people with impaired vision or, conversely, for those who want to fit more information on one screen.
The settings are in Settings → Screen → Text and Element Size. As you move the sliders, you can see that changing the text size does not always proportionally change the indentations between the lines or the size of the buttons. For maximum control, use the Advanced Settings mode (if available in your shell version), where you can set a specific DPI value (dots per inch).
- 📏 Reducing the size of elements allows you to fit more lines on the screen.
- 👓 Enlarging the font improves readability without losing the menu structure.
- ⚙️ Reset to "Standard" size solves problems with "got" layout in applications.
There is also a hidden possibility of changing the density of the interface through an engineering menu or ADB-It's a very careful change in the system setting. smallest_width It can cause some applications to become unreadable or stop running. Standard shell tools can safely scale within the range of 20-30% The value is usually enough for any task.
⚠️ Attention: With a strong reduction in the scale of the interface (increase) DPI) The controls in some banking applications may become too small or run over each other, making them difficult to use.
Adjust response time and sensitivity of touch screen
Sensor response speed is critical for mobile gaming enthusiasts. In Xiaomi gaming smartphones and the K and Pro series, the Touch sampling rate is often found in the Game Turbo game accelerator or in the main screen settings. Increasing this parameter makes control more responsive, reducing the delay between touching a finger and acting on the screen.
However, high sensitivity can play a cruel joke when using protective glasses or films. If the screen reacts to random palm edge casting or behaves unstable with protection, in the screen settings (often in the hidden menu or through the code # # # #6484##) you can find the option "Mode in gloves" or "High sensitivity", which activates the touch screen signal by breaking through the protective glass layer.
☑️ Touchscreen check
Also worth mentioning is the gesture control function. Switching from navigation buttons to full-screen gesture control frees up useful screen area, but requires getting used to. In the settings Additional → Full-screen mode, you can adjust the return area and sensitivity of the side edges to exclude random swipes while playing or watching videos.
💡
Not only is the high Hertsovka (Hz) value important for games, but the high frequency of the Touch Sampling Rate, which is measured in Hertz separately and is responsible for the speed of the response to touch.
Additional functions and problem-solving
Xiaomi's ecosystem offers a number of unique features for display, including the Always On Display, which shows the time and notifications on the phone that's off, and it's flexible to choose style, running times (on schedule or 10 seconds after touching), and even upload your images. It's not only beautiful, it's functional.
Often users are faced with the problem of "burnout" AMOLED matrices or the appearance of artifacts. To prevent burnout, the system has a feature "Shift image" on Always On Display, which unobtrusively shifts the picture. If you notice yellow spots or stripes, it is likely physical damage, but software resetting screen settings or calibration through the engineering menu sometimes helps to remove software glitches of colors.
- 🔋 Set up Always On Display on a schedule to save battery life.
- 🛡️ Enable "Protection against accidental touch" in your pocket.
- 🔄 Use "Imagine Shift" to Prolong Life AMOLED matrix.
In case of serious color rendering problems (for example, a strong pink or green hue on a white background at low brightness), it is worth checking for system updates. Xiaomi periodically releases patches that improve the performance of display drivers. If the problem is not solved by the update, you may need to replace the screen module, as this can be a sign of degradation of organic LEDs.
