How to set up the screen on Xiaomi Mi 9T: a complete display guide

The Xiaomi Mi 9T screen with Super AMOLED technology is one of the key advantages of this smartphone, but not all users know how to unleash its potential 100%. Even after buying, many leave factory settings, unaware that the correct calibration can significantly improve the perception of the picture, reduce eye strain and extend the life of the matrix. In this article, we will analyze all the hidden and obvious parameters of the display, from basic brightness adjustment to fine tuning the color profile and refresh rate.

Feature of the Mi 9T — support HDR10 and a wide range of colors DCIP3, But by default, these functions are often disabled or not working optimally, AMOLED-screens are prone to pixel burnout when settings are incorrect, so it is important to understand which parameters should be changed, and which ones should be left “as is”. We will also touch on the issues of power consumption – because the screen consumes up to 40% of battery power, and a competent setup can extend the autonomy of the device.

Basic brightness and adaptive mode settings

The first thing to start with is brightness control. The Mi 9T has two main modes: manual tuning and adaptive brightness, manual mode is suitable for stable lighting conditions (such as at home or in the office), and adaptive mode automatically adjusts to ambient light, to change the parameters:

1. Open the Settings → Display.
2. Move the Brightness slider manually or activate the Adaptive Brightness switch.
3. To fine-tune the adaptive mode, tap the gear next to the switch.

The adaptive brightness in the Mi 9T is based on the light sensor data, but can sometimes fail, such as dimming the screen too much at dusk.

• 🔄 Reset sensor calibration: in the adaptive brightness menu, select Reset and follow the instructions on the screen.
• 🌓 Turn off the function in the dark: if the smartphone too aggressively reduces the brightness at night, set a time limit in the settings of sleep mode.
• 🔋 Check the energy saving: in Battery mode → Energy saving brightness can be automatically limited.

⚠️ Note: If after the update MIUI And the adaptive brightness stopped working, so try to recalibrate the sensor, so close the screen with your palm for 5 seconds, then remove your hand, and the system needs to restart the sensor.

For users who are often outdoors, it is useful to include the option “Improved Contrast” (in the submenu of Additional), which increases the visibility of text in bright sun, but can slightly distort colors in dark scenes.

Setting the color profile and temperature

Xiaomi Mi 9T offers three preview color profiles: Standard, Saturated and Soften. By default, activated saturated, which emphasizes the brightness of AMOLED, but can distort real colors (especially skin tones in photos).

1. Go to Settings → Display → Color mode.
2. Choose one of three options or activate Auto (changes depending on the content).
3. For manual calibration, tap Additional settings.

In the menu Additional settings are available:

• 🎨 Color temperature: from Cold (blueish hue) to Warm (yellowish, gentle for the eyes).
• 📊 Color gamut: sRGB (natural colors) or DCIP3 (extended range, suitable for HDR-content).
• 👁️ Reading mode: Blue light filter with adjustable intensity (useful for evening use).

For professional calibration (for example, for working with photos), it is recommended to use the sRGB profile and the Standard temperature. If you want juiciness in games and videos, choose DCIP3 with the Saturated profile.

Screen refresh rate and animation smoothness

The Xiaomi Mi 9T has a 60Hz refresh rate screen, but MIUI has hidden settings to optimize the smoothness of the interface. Although it is impossible to change the refresh rate on this device (unlike the POCO F1 or Redmi Note 10 Pro), you can adjust the animation system and the speed of transitions:

1. Activate Developer Mode: Go to Settings → About Phone and tap the MIUI version 7 times.
2. Back to Settings → Additionally. → For developers.
3. Find sections: Window animation speed (recommended 0.5x) Transition animation speed (recommended 0.5x) Disable animation (for maximum performance)

Reducing the speed of animation makes the interface visually faster, but can cause discomfort for users who are accustomed to smooth transitions. Complete disabling of animation (Animation = Off) gives an increase in productivity by 5-10%, but the interface will become more “ragged”.

⚠️ Note: Developer mode also has an option GPU-It can improve smoothness in games, but it increases processor heat and battery consumption. Use only when necessary (for example, for heavy loads). 3D-game).

To check the actual refresh rate of the screen, you can use applications like Display Tester (available on Google Play).If the test shows a value below 58-60 Hz, this may indicate software limitations of MIUI or problems with display drivers.

Enable the developer mode

Set the animation speed to 0.5x

Hidden functions AMOLED-Screen: Always-On Display and Burnout Protection

One of the key advantages AMOLED-The displays support Always-On Display (AOD) — function, in which the screen is turned off, displays time, notifications and other data. 9T It doesn’t work as well as on Samsung or Google Pixel flagships, but if set up properly, it can be useful:

1. Go to Settings → Screen Lock → Always-On Display.
2. Choose the display style (analog or digital watch).
3. Set up a schedule or leave Always mode (increases battery consumption).
4. Turn on the option to show notifications if you need to see missed calls and messages.

💡

If you already have burnout signs on your screen (such as weak navigation key contours), try to “show” them with special YouTube videos that cycle the colors of the pixels, which will not eliminate the problem completely, but will make it less noticeable.

Screen resolution and scaling

The Xiaomi Mi 9T has a resolution of 2340×1080 (Full HD+), but you can change the pixel density (DPI) in the settings, which affects the size of the interface elements, which is useful for users with visual problems or those who want to put more information on the screen.

1. Open Settings → Display → Text size and display.
2. Select the Display Scale and move the slider (from Small to Huge).
3. To fine tune, activate Developer Mode and change the Minimum Width setting (default value is 440dp).

Scaling down (like 400dp) allows you to place more icons on the home screen and increase the number of lines on the menu, but text can get too small. zooming in (up to 480dp) makes reading easier but reduces the workspace.

⚠️ Attention: Change DPI In the case of a developer mode, it may cause some applications to crash (e.g., banking clients or games) if the interface is not displayed correctly after the zoom change, return the value. 440dp and reboot the smartphone.

To check the actual screen resolution, you can use the Screen Test application. If it shows a value below 1080p, this may indicate an activated power saving mode or driver error (reset).

💡

Changing the screen size does not affect the actual resolution of the matrix, but only the size of the interface elements. To view content in the original resolution (for example, 4K video), use third-party players like VLC.

Screen settings for games and multimedia

For gamers and video enthusiasts, the Xiaomi Mi 9T offers a few hidden features that enhance the experience:

• 🎮 Game mode: disables notifications and optimizes performance. activated by swipe on both sides of the screen in landscape mode.
• 📺 HDR-Mode: automatically activates when you view compatible content (Netflix, YouTube) HDR).
• 🔊 Sound amplification: in Settings → Sound. → Sound effects can be turned on Bass amplifier for speakers.

To manually enable HDR in games (if supported):

1. Set a color profile and DCIP3 range.
2. In the game graphics settings, select the maximum texture quality.
3. Turn off the energy saving in the Settings → Battery.

If there are artifacts or slowdowns in the games, try:

• 🔧 Reduce the rendering resolution in the game settings.
• 🔄 Disable VSync (if available).
• 📱 Turn it on. GPU-Acceleration in Developer Mode (see section above).

On Mi. 9T activated HDR-The screen consumes up to 30% of the charge per hour in maximum brightness. → High performance only with a connected charger.

Resolving screen problems: flickering, broken pixels, sensor

If the Mi 9T screen starts to behave incorrectly (shimmers, does not respond to touch or shows artifacts), first check the software settings:

• 🔄 Reboot your smartphone – many screen glitches disappear after a reboot.
• 📱 Reset the display settings: Settings → System system → Resetting settings → Resetting screen settings.
• 🔋 Check adaptive brightness: Sometimes flickering is caused by light sensor conflict.

If the problem is hardware (such as broken pixels or a broken sensor), try:

1. Test the screen for defects using the Dead Pixel Test app.
2. If the pixels are stuck (don’t change color), use JScreenFix to overclock them.
3. If the sensor malfunctions, check if it is caused by a drop or moisture, in which case you will need to replace the display module.

To check the sensor for responsiveness:

1. Go to Settings → About Phone → All Specifications → Equipment Test.
2. Select the Sensor Test and follow the instructions on the screen.

⚠️ Note: If after the update MIUI The screen has started to display green or purple stripes, which may be caused by a failure in the display driver. Try to roll back to the previous firmware version via Fastboot or contact the service center.
