How to Improve the Screen Quality on Xiaomi Phone: From Color Calibration to Hidden Settings MIUI

Screen quality on Xiaomi, Redmi and smartphones POCO It's often a key factor in choosing a device, but even the top models with the most advanced models. AMOLED-display IPS-High-resolution matrices can be frustrating with dull colors, incorrect color reproduction, or blurred text, and the reasons are not only hardware limitations, but also factory settings. MIUI, which are optimized by default to save battery life, not for maximum visual comfort.

In this article, we will discuss 7 practical ways to improve the display on the screen of your Xiaomi — from basic brightness and contrast settings to hidden functions of color calibration and resolution optimization. HDR For video, eliminate font blur, adjust the color temperature for the time of day, and even fix artifacts on the screen without contacting the service. 13/14 series, Redmi Note 12/13 Pro and POCO F5/X5, It is also suitable for other devices on MIUI 14/15.

Importantly, some settings can affect the autonomy of the smartphone, and we will specify which ones are safe for the battery and which should be used only when connecting to a charge.

1. Optimization of the basic screen parameters in MIUI

The first step to improving image quality is to adjust the standard display settings. MIUI They're hidden in multiple sections, and their combination has a noticeable effect even without the use of third-party utilities.

Go to Settings. → Display and pay attention to the following parameters:

• 🌞 Adaptive brightness: Turn it off if the screen is too dim in sunny weather. Manual brightness control (a slider in the notification curtain) gives a more predictable result.
• 🎨 Reading mode: Turn it on for a warm glow in the evening, but don’t use it during the day – it distorts the color reproduction.
• 🔍 Font size and display: scale down to 80-85% increase the density of pixels (PPI), Make the text and icons clearer.
• 🖥️ Screen resolution: some models (e.g. Xiaomi 13 Ultra) have switching between FHD+ and QHD+. Choose the maximum for detailing.

Hidden function: in Settings → Display. → Additionally (on some firmware) there is an option called Color Mode. Choose Saturated for bright colors or Standard for natural transmission. Mode P3 (if available) expands color coverage - useful for viewing HDR-content.

⚠️ Attention: on Redmi with budget IPS-matrices (e.g. Redmi) 12C) Saturated mode can lead to unrealistic colors. Check the display of skin tones in photos.

2. Color calibration: hidden settings MIUI

Factory color calibration at Xiaomi is often criticized for being too cold or yellow. MIUI There is a tool for fine-tuning – Color Lab, but it is hidden from the user.

To open it up:

1. Go to Settings. → The phone.
2. Tap 5 times on the line version MIUI (A notice will appear saying, “You have become a developer").
3. Back to Settings → Additionally. → For developers.
4. Find the option Color Profile or Screen Calibration (name depends on the model).

Inside you will find sliders for adjustment:

• 🔴 Red/Green/Blue (RGB-balance - adjusts the color shade.
• 🌡️ Colour temperature (from 2500K before 10000K) — The lower the value, the warmer the screen.
• 📊 Gamma – Affects contrast in dark scenes.

Adjustment recommendations:

• For natural flowers: set the temperature 6500K (sRGB).
• For reading at night: lower the temperature to 4000K and reduce the blue channel to 10-15%.
• For games and videos: Increase the saturation of green by 5% for more juicy shades.

Set the temperature. 6500K|

Balance RGB (100/100/100)|

Increase the scale to +5 for better visibility in the dark|

Turn off "Adaptive Color" (if any)-->

3. Inclusion HDR video enhancement

Xiaomi smartphones with AMOLED-screens (e.g. Xiaomi) 13 pro POCO F5 Pros support HDR10/10+, But this feature is often disabled by default:

For YouTube:

1. Open the tagged video HDR.
2. Slip on three points in the upper right corner. → Quality.
3. Choose the maximum resolution with a note HDR.

For Netflix and other streaming services:

• 📺 Make sure that the application settings have Mode enabled HDR.
• 🔋 Connect charging – some models limit HDR low-charge.
• 📶 Use Wi-Fi – Mobile internet may not provide enough speed to HDR.

Problem: on some devices (e.g. Redmi Note 11 Pro)+) HDR It only works in apps, not in a gallery:

1. Install Google Photos from the Play Market.
2. Open up. HDR-photo → press three points → Details. → Show in HDR.

⚠️ Attention: Continuous use HDR on AMOLED-It's the pixel burnout that speeds up screens, and you only turn it on for viewing content, not for interface.

4. Elimination of blurring of text and icons

Blurred text or fuzzy icons on Xiaomi are a common problem, especially after an update MIUI. Causes:

• 🔍 Incorrect screen resolution (for example, HD+ instead FHD+).
• 📱 Failure in font rendering (MIUI They use their own font system).
• 🛠️ Optimizing performance, reducing detail.

Decisions:

1. Reset the font settings: Settings → Display. → Type size and style → Drop it.
2. Turn off font smoothing (Developers only): Settings → For developers → Delete "Font smoothing"
3. Install a third-party launcher (like Nova Launcher) if the blur is only on the desktop.

For models with 90/120/144 Hz, for example, POCO F5):

• 🔄 Set the refresh rate to 60 Hz in Settings → Display. → Update frequency – this can reduce artifacts when scrolling.
• 🎯 Turn on Adaptive Frequency if available – it automatically adjusts to the content.

💡

If blurring only appears in certain apps (like Chrome), try turning on the Visually Impaired mode, which is paradoxical but sometimes improves text rendering.

5. Color rendering setting for photographers and designers

If you work with colors professionally, Xiaomi's factory calibration won't suit you.

Step 1. Use color profiles:

• 📱 Xiaomi. 12/13/14 Series available profile DCIP3 — It is closer to Adobe standards. RGB.
• 🖥️ For Redmi with IPS Select sRGB, it is the most predictable.

Step 2: Calibrate the screen with the following applications:

• 📊 Display Calibration (Play Market) – lets you create a new ICC-profile.
• 🎨 Screen Balance – for fine-tuning RGB-balance.

Step 3. Check the color reproduction:

• Download test images from Lagom LCD Test.
• Evaluate the gray gradients, the black level and color transitions.

Example: on the Xiaomi 13 Pro, after calibrating through Display Calibration, the delta E (color deviation indicator) decreased from 4.2 to 1.8, which corresponds to professional monitors.

⚠️ Note: After installing third-party color profiles, some apps (such as Instagram or Lightroom) may be disrupted.

6. Hardware problems: when settings don't help

If the screen remains dim, with broken pixels or stripes even after all the settings, the problem may be hardware.

For diagnosis:

1. Run the screen test via the engineering menu: ##6484## (some models may have different code).
2. Check the screen for broken pixels with the Dead Pixel Test app.
3. If the artifacts only appear when heated, the problem is with the display controller.

On Xiaomi models with LTDPO AMOLED (Xiaomi 14, for example) flickering at low brightness is a well-known problem that can only be fixed by replacing the screen with a warranty.

7. Optimization for Games: Framerate and Response

For gamers, screen quality is determined not only by colors, but also by refresh rate, response time and tactile return.

Frequency of update:

• 🎮 For POCO F5 or Redmi K60 Set 120 Hz or 144 Hz in Settings → Display. → Frequency of update.
• 🔋 Enable Adaptive Frequency if the game supports it (e.g. Genshin Impact or Call of Duty Mobile).

Tactical response:

• 🎯 Turn it on. 4D-vibration in Settings → Sound and vibration → Vibration on touch.
• 🕹️ In games, for example, PUBG Mobile: adjust the sensor sensitivity to maximum.

Color profiles for games:

• 🎨 For shooters (such as Free Fire) increase contrast in Settings → Display. → Additionally.
• 👁️ Turn on Eye Mode for Long Sessions – It Reduces Fatigue.

💡

On Xiaomi Black Shark and POCO F Series for maximum performance in games MIUI Optimization in the developer settings. This will reduce input delays, but can increase heating.
