Modern smartphone users often encounter mysterious settings that lurk deep inside the MIUI interface. One of the features that has raised questions among Xiaomi Poco F3 owners is the so-called “AI visualization system,” which many confuse with conventional screen settings, but it is a deeper software package responsible for rendering images.
In fact, it's a combination of the hardware capabilities of the E4 AMOLED array and the software algorithms for processing video. The Snapdragon 870 processor in this model has a powerful video core that can decode high-resolution content without delay, and it's the CPU and display bundle that creates that very "live picture" effect.
Understanding how this system works allows the owner of the device to make the most of the screen, so you can customize color reproduction to your preferences, activate dynamic range, and even optimize power consumption, and let's go into detail about how this technology works and what hidden controls it provides.
Technical features of the display and the role of the processor
The basis of the entire visualization system in Poco F3 is of high quality OLED-This is not just a marketing ploy, but a real advantage, because this type of panel provides a deep black color due to the ability to completely shut down the pixels.
The key element here is support for HDR10+, which means that the smartphone is able to dynamically change the brightness and contrast for each frame of video. If content is shot with HDR support, the system automatically expands the color gamut, making light areas brighter and dark areas more detailed.
⚠️ Attention: Continuous use of maximum brightness in mode HDR This can cause the organic pixels to burn out faster. Try not to keep the brightness slider at maximum in static scenes.
Importantly, 120Hz refresh rates are also regulated by artificial intelligence algorithms. The system analyzes the content on the screen: if you flip through the news feed, the high hertz is turned on for smoothness. If you read text or watch a static photo, the frequency can decrease to save battery power.
Why E4 AMOLED?
How Algorithmic Image Processing Works
Artificial intelligence in a display context is a set of predictive algorithms that not only display a picture, but also predict what a user wants to see, for example, when a game is launched, the system can automatically switch to a color saturation mode and a faster touchscreen response.
In the settings, this is the responsibility of Settings → Screen → Color Scheme, where you can choose one of the preset profiles or create your own. The Color Vision algorithm analyzes the dominant colors on the screen and adjusts the white balance so that the image seems more natural to the human eye.
And you should pay special attention to Reading mode, which is part of the visualization system, and when it's activated, it goes into monochrome mode or changes the color temperature to a warmer one, which reduces the strain on the eyes during prolonged interaction with textual content.
- 🎨 Adaptive brightness: the light sensor reads the light in the room and smoothly changes the backlight.
- 🎬 MEMC (Motion Estimation, Motion Compensation: The technology of adding intermediate frames for smooth video (does not work in all applications).
- 👁️ Vision protection: programmatic reduction of blue spectrum radiation without strong yellowness.
💡
To calibrate the color, use the Themes app -> Profile -> Create where you can manually adjust the gamut and saturation for each color channel.
Customize screen settings for maximum performance
For the visualization system to work properly, you need to set the basic parameters correctly. Go to the Settings menu → Screen. First of all, make sure that the resolution is set to a maximum of 2400×1080. Decreasing the resolution can save charge, but blur fonts and icons.
Next, you need to choose the refresh rate. Poco F3 has three options: 60 Hz, 90 Hz and 120 Hz. For everyday use, the default mode is optimal, where the system decides when to increase the hertz. Forced on 120 Hz in all applications can cause micro-freezes in poorly optimized programs.
The DC Dimming feature, which combats screen flickering at low brightness, can be activated through a hidden menu, requires you to quickly click on the kernel version in the About Phone section several times to get the developer menu to appear, and then find the Anti-flicker mode item.
| Parameter | Recommended value | Impact on autonomy |
|---|---|---|
| Frequency of update | By default (Auto) | Average. |
| Permission | 2400×1080 | High. |
| Dark subject matter | Included. | Low (saving charge) |
| Adaptive brightness | Included. | Low. |
☑️ Optimal screen setting
Game scenarios and Game Turbo mode
Poco F3 owners often use their smartphone for mobile gaming, and here the visualization system plays a critical role: the Game Turbo built-in module intercepts the control of the display when launching games, it increases the sensitivity of the touchscreen and changes the color reproduction for better visibility of enemies in the dark corners of the map.
In game mode, the Vision Improve feature is available, which programmatically increases contrast and saturation, making the picture more "nuclear"; it does not change the original file of the game, but only corrects the output image on the fly. For shooters and competitive projects, this gives a small but tangible advantage.
However, it is worth remembering that activating all visual enhancements in games increases the load on the GPU. This can lead to faster heating of the case. If you notice a drop in FPS (frames per second), try turning off the “improvers” in the Game Turbo settings for a particular application.
Energy consumption and optimization of the display
The screen is the most energy-intensive element of a smartphone. Xiaomi’s visualization system tries to balance image quality with battery life. Algorithms analyze your behavior: if you rarely watch high-resolution video, the system may suggest lowering the quality of streaming video in apps to save traffic and energy.
Autobrightness uses machine learning, and over time, the smartphone remembers what brightness you prefer in a particular place and time of day, for example, at home in the evening it will turn the lights down, and outside on a sunny day it will add, a process that takes several days of active use.
⚠️ Note: If the autobrightness is not working correctly (changes values sharply), try resetting the sensor calibration in the engineering menu or simply restarting the device.
Also worth mentioning is the screen sleep timer: setting a 30 second or 1 minute value is optimal. Too long before locking causes the screen to burn to waste while you're distracted from the phone.
Advanced settings through the engineering menu
For advanced users who want to gain full control of the visualization system, an engineering menu is available, which allows you to adjust parameters hidden from the average user. Be careful: incorrect changes can lead to incorrect display of colors or unstable interface.
To get to the menu, open the Phone app and enter the code ##6484##. From the list that opens, select the item associated with the display (usually marked as Display or Screen), where you can test for broken pixels, check the sensor and calibrate colors.
One of the useful features on this menu is resetting the accelerometer and gyroscope calibration, which indirectly affects the auto-rotation of the screen. If your Poco F3 is "stupid" when turning from portrait mode to landscape, resetting the sensor settings in this menu often helps solve the problem.
The path to the screen test:
CIT (Engineering Mode) → Display / Screen → Start Test💡
The engineering menu is a powerful diagnostic tool, but don’t change the Value unless you know exactly what they’re responsible for.
