Xiaomi Redmi Note 12 screen: a complete guide to characteristics, settings and repairs

Smartphone Xiaomi Redmi Note 12 became one of the most talked about devices of 2023 - and its display played a significant role in this. The manufacturer took a bold step by offering users a choice between two types of screens: AMOLED in top modifications and IPS in basic versions. This approach raised a lot of questions: which display is better for the eyes? Is it worth paying extra for AMOLED? How to avoid pixel burn-in? And why do some users' screens begin to "flicker" after a month of use?

In this article we will look at unique features of Redmi Note 12 displays, which are not advertised in official specifications - from hidden color modes to hardware limitations when connecting to a PC. You'll learn how to properly calibrate your screen for graphics, why brightness drops when the battery is low, and what settings can help reduce eye strain during extended use. And for those who have encountered problems, we have prepared a checklist for diagnosing faults and tips for choosing an original module when replacing.

Redmi Note 12 display specifications: comparison of versions

Ruler Redmi Note 12 includes several models with different screens. Basic versions (Note 12 4G/5G) equipped IPS matrices with permission FHD+ (2400×1080) and update rate 90 Hz or 120 Hz (depending on the region). Top modifications (Note 12 Pro/Pro+) received AMOLED displays with support 120 Hz, HDR10+ and peak brightness up to 1200 nits.

Key differences between versions:

• 🔹 Matrix type: IPS (Note 12) vs AMOLED (Note 12 Pro/Pro+). The latter provide deeper blacks and high contrast, but may suffer from burn-in of static interface elements.
• 🔹 Refresh rate: 90 Hz for basic models and 120 Hz for Pro versions. The difference is noticeable when scrolling through lists and in fast-paced games.
• 🔹 HDR support: only for AMOLED versions. This is important for watching videos in Netflix or YouTube with extended dynamic range.
• 🔹 Screen protection: all models are equipped with glass Corning Gorilla Glass 3, but in Pro versions it is thinner (0.6 mm versus 0.7 mm in basic ones), which increases the risk of damage from falls.

Interesting fact: in Note 12 Pro+ used display from Samsung E4 - the same as in flagship devices Samsung Galaxy S22. This explains the high color rendering (coating 100% DCI-P3) and low power consumption when displaying dark themes. However, in budget versions, IPS matrices supply BOE, and their quality may vary from batch to batch.

AMOLED vs IPS: which is better for eyes and battery?

Choice between AMOLED And IPS - it's always a compromise. AMOLED screens provide richer colors and deeper blacks (the pixels are simply turned off), but have two serious drawbacks:

1. Pixel burn-in. Static interface elements (for example, the navigation bar) become “imprinted” into the matrix over time. B Redmi Note 12 Pro Xiaomi is trying to combat this with a feature DC Dimming, but it doesn't work perfectly.
2. Flickering at low brightness. Due to the peculiarities of PWM regulation (pulse width modulation), some users complain of eye fatigue when reading in the dark.

IPS matrices do not have these problems, but they lose in contrast and energy efficiency. For example, when watching a video with a predominantly black background (as in OLED TVs) AMOLED version Note 12 Pro consumes battery 15–20% slower than the IPS version.

Is it better for the eyes?

• 👁️ In daylight: AMOLED thanks to high brightness (up to 1200 nits against 500 nits at IPS).
• 🌙 In the dark: IPS if AMOLED flickering annoys you. Turn on the mode Reading (Settings → Display → Reading mode) to reduce the load.
• 🎮 For games: AMOLED due to higher refresh rate (120 Hz) and shorter response time (1 ms against 4–5 ms at IPS).

Hidden display settings: how to improve the picture

Xiaomi hides some of the display functions in the engineering menu. To get there, enter in the application Phone code:

*#*#36446337#*#*

In the menu that opens CIT select Display - here you can:

• 🎨 Calibrate colors according to standards sRGB or DCI-P3 (useful for graphic designers).
• 🔄 Disable adaptive brightness, which sometimes malfunctions.
• 📊 View display operating time (field Panel On Time) - this will help track matrix wear.

In normal settings (Settings → Display) there are also useful options:

• 🌈 Color Mode: select Saturated for bright photos or Standard for natural shades.
• 👓 Eye protection: turn on Blue light filter and set up a schedule (optimally - from 21:00 to 7:00).
• ⚡ Adaptive frequency: disable it if you notice jerks when scrolling (in some firmware the function is unstable).

How do I reset my display to factory settings?

Go to Settings → System → Reset settings → Reset display settings. This will help if, after updating MIUI, the colors have become unnatural.

Important: in Redmi Note 12 Pro+ there is a hidden function Super Resolution to scale video up to 4K. To activate it, you need:

1. Install the application Activity Launcher from Google Play.
2. Find activity in it com.miui.videotoolbox.
3. Enable option Super Resolution manually.

Common display problems and their solutions

According to service centers, most often users Redmi Note 12 face the following problems:

Problem	Reason	Solution
Screen flickering at low brightness	PWM adjustment in AMOLED displays	Turn on DC Dimming in Settings → Display → Advanced
Yellow spots around the edges	Peeling of the LED substrate (assembly defect)	Contact the warranty service - the display module needs to be replaced
Spontaneous change in brightness	Light sensor failure	Calibrate the sensor through the engineering menu (*#*#36446337#*#* → Sensor → Light Sensor)
Scrolling artifacts (strips, torn edges)	Adaptive refresh rate conflict	Disable Adaptive frequency in display settings
Black screen when connected to PC	Incompatible with some video cards (for example, NVIDIA GTX 10xx)	Update your drivers or use Mi PC Suite to transfer files

Particular attention should be paid to the problem "green lines", which appears for some users after a fall or overheating. This indicates damage to the display cable. In 80% of cases, only replacing the screen helps, but before that try:

Reboot your phone in safe mode|Check if lines appear when connected to charging|Test the display on another device (if possible)|Contact service to check the cable and controller-->

⚠️ Attention: If, after replacing the display in an unofficial service, problems with the sensor appear (for example, “ghost” touches), most likely, a non-original module was installed. B Redmi Note 12 the sensor and display are soldered into one unit, and cheap analogues often have poor calibration.

How to extend the life of your display: operating tips

Average AMOLED display lifespan: 3–5 years with intensive use, IPS lasts longer (5–7 years). To delay wear as much as possible:

• 🔋 Avoid completely draining the battery. When the charge level is below 10%, the display controller automatically reduces the brightness, which increases the load on the matrix.
• ☀️ Don't use your phone in the sun. Overheating higher 40°C accelerates the degradation of organic light-emitting diodes in AMOLED.
• 📵 Turn off Always-On Display. Constantly lit pixels (like a clock) will burn out faster. B Note 12 Pro this feature can be disabled in Settings → Screen lock.
• 🎮 Limit your gaming time at maximum brightness. In mode Game Turbo The display operates at its maximum capacity, which reduces its resource.

Other recommendations are relevant for IPS screens:

• 🖥️ Don't press on the screen. IPS matrices are sensitive to mechanical stress - this can lead to the appearance of “broken” pixels.
• 🔄 Update your firmware regularly. New versions of MIUI optimize backlight control algorithms, which reduces power consumption.

⚠️ Attention: if you use Redmi Note 12 for shooting video in 4K, avoid long-term recording in bright sunlight. Overheating of the camera may cause the display brightness to automatically decrease to 30%, which will ruin the footage.

Display replacement: original vs analogues, prices and pitfalls

Display replacement cost in Redmi Note 12 varies from 3 000 to 12 000 ₽ depending on the model and type of matrix. Original modules for Note 12 Pro+ (with AMOLED from Samsung) are the most expensive - up to 10 000 ₽ only for spare parts. Basic IPS screens can be found at 2 500–4 000 ₽, but here it is important not to run into a fake.

How to distinguish the original:

• 🏷️ Availability of hologram on a train with a logo Xiaomi and serial number.
• 🔍 Build quality: in the original the sensor is glued without gaps, and the glass Gorilla Glass has a logo Corning when illuminated by a flashlight.
• 📦 Packaging: branded modules are supplied in black antistatic bags with a red logo Mi.

Price comparison (as of August 2026):

Model	Original display (₽)	High-quality analogue (₽)	Savings (%)

Redmi Note 12 Pro+ (AMOLED, Samsung E4)	9 500	5 500	42%

⚠️ Attention: when replacing the display in an unofficial service, the function may disappear Always-On Display or HDR. This is due to the fact that cheap analogues do not support all protocols of the original matrix. Before replacing, check with your technician to see if all functions will be retained.

FAQ: answers to frequently asked questions about the Redmi Note 12 display

Why does the Redmi Note 12 Pro screen flicker at low brightness?

This is a feature of PWM brightness control in AMOLED displays. To reduce flicker:

1. Activate DC Dimming in display settings.
2. Use dark themes - below 30% brightness the flickering is less noticeable.
3. Update the firmware: In MIUI 14.0.5 and later, the PWM frequency is increased from 240 Hz to 480 Hz.

Is it possible to disable adaptive refresh rate?

Yes, for this:

1. Go to Settings → Display → Screen refresh rate.
2. Select a fixed value (60 Hz, 90 Hz or 120 Hz depending on model).

Please note: in some regional firmware this option is hidden. To unlock it, you need to change the region to India through Settings → Advanced → Region.

Why does my phone screen go blank when connected to a PC?

This problem is due to a communication protocol conflict. Solutions:

• Use original cable USB-C from Xiaomi (cheap analogues do not support DisplayPort Alt Mode).
• Update your video card drivers on your PC (especially important for NVIDIA And AMD).
• Turn on the mode File Manager (MTP) instead of Charging when connected.

If all else fails, try connecting via wireless display (Miracast) or use the application Scrcpy to control your phone from a PC.

How to check your display for dead pixels?

Download the app Screen Test from Google Play and take the tests:

1. Color fills (red, green, blue, black, white).
2. Gradient to check the smoothness of transitions.
3. Touch test for touchscreen diagnostics.

Dead pixels on AMOLED look like constantly burning dots, on IPS they look like black or colored dots that do not change color when the fill changes.

How much does it cost to replace glass (without matrix) on Redmi Note 12?

In official services Xiaomi They don’t practice replacing only glass - they always change the entire display module. In unofficial workshops you can find a glass replacement service for 1 500–2 500 ₽, but:

• The warranty for such repairs usually does not exceed 1 month.
• There is a risk of damaging the sensor or matrix during disassembly.
• The quality of gluing may be worse than the original one (bubbles, peeling).

We recommend weighing the risks: sometimes it is cheaper to replace the entire module than to repair the glass.
