Why the screen on the phone or TV Xiaomi โ€“ a full analysis of the causes and solutions

Flickering, ripples or waves on the screen of Xiaomi devices is one of the most annoying problems that users face. Symptoms can manifest themselves in various ways, from a barely noticeable jitter of the picture to aggressive blinking at 1-2 Hz, making it impossible to use the gadget. In 80% of cases, software failures are to blame, but ignoring hardware malfunctions is dangerous - they can lead to a complete failure of the display.

In this article, we will analyze all possible causes of ripples on the screens of Xiaomi smartphones, tablets and TVs, from banal application conflict to critical damage to the matrix. You will learn how to diagnose the problem yourself, which settings to check first, and when exactly to carry the device in the service. AMOLED-screens (Redmi Note 12 Pro)+, POCO F5, Xiaomi 13T), where the ripples are often associated with the features of the control of lighting.

1. Software failures: firmware, drivers, and application conflicts

To start with, the most innocuous, software problems, which account for up to 60 percent of Xiaomi screen ripples, can be fixed without disassembling the device.

  • ๐Ÿ“ฑ Unstable version MIUI โ€” especially relevant for beta firmware or fresh global updates (e.g., switching from MIUI 13 on 14).
  • ๐Ÿ”„ Conflict of graphics drivers โ€“ often manifests itself after updating through OTA, When new drivers are incompatible with old settings.
  • ๐ŸŽฎ Applications with Aggressive Optimization FPS โ€” Genshin Impact or Call of Duty Mobile games can break the refresh rate of the screen.
  • ๐Ÿ” Failures in Google Play services are rare, but occur on devices with custom firmware (for example, Pixel Experience on the Internet). POCO X3).

How do you check? Run your phone in Safe Mode (press the power button โ†’ Safe Mode) If the ripples are gone, it's the third-party app's fault, if it's left, it's a problem in the system or hardware.

โš ๏ธ Attention: On Xiaomi models 12S Ultra and Redmi K50 Gaming ripples may appear due to a bug in the technology LTPO (dynamic update rate change. Check if the flicker frequency matches the switch between 1-120 Hz in the screen settings.

2.Screen settings: refresh rate, adaptive brightness and color profiles

Often users activate features that trigger ripples, such as adaptive refresh rates. AMOLED-The screens may conflict with the energy saving settings:

  1. Screen refresh rate: Go to Settings โ†’ Display โ†’ Update rate. Try to lock in at 60Hz or 120Hz (if available).
  2. Adaptive brightness: Turn it off in Settings โ†’ Display โ†’ Brightness. Sometimes the light sensor doesn't work properly.
  3. Color profile: Set โ€œStandardโ€ instead of โ€œSaturatedโ€ or โ€œSmoothโ€ in Settings โ†’ Display โ†’ Color mode.
  4. Read Mode: Deactivate it if ripples appear when a dark topic is turned on.

On Xiaomi Mi TVs (e.g. Mi TV Q2 75), ripples may be associated with the MEMC (engine compensation) enabled. Turn it off in Settings โ†’ Image โ†’ Engine compensation.

3. Hardware problems: plume, matrix and display controller

If the software methods didn't work, it's time to look at the hardware malfunctions, and they can be divided into three categories:

ComponentSymptomsReason.Decision
Display plumeRibbons when pressed on the screen, "waves" when bending the bodyOxidation of contacts, mechanical damageReplacement of the plume (cost 500-1500) โ‚ฝ)
MatrixPermanent ripples with artifacts (strips, dots)Burning of pixels, damage to backlightReplacement of the matrix (from 3000) โ‚ฝ)
Display controllerRifle + non-working touchscreen or backlightOverheating, short circuit.Replacement of the controller or repair of the controller
BatteryRibbons with low charge (<15%)Power drawdown due to battery wearBattery replacement

The simplest test for hardware problems is to tap the screen in different places, and if the ripples get worse when you press the top or bottom, it's almost certainly the plume. On the Redmi Note 10 Pro and POCO X4 Pro, this is a common problem because of the thin body.

How to check the plume without disassembly?
Bend the phone case carefully (don't overdo it!) If the ripples appear when you bend, the plume is damaged. Also try connecting the phone to your PC and moving the cable: if the picture on the computer screen is stable and the phone is rippling, the problem is exactly in the display or its connection.

4.Power problems: charging, battery and power supply

Unstable power is one of the most insidious causes of ripples, and symptoms can only occur when you plug in a charge or when your battery is below 20 percent.

  • ๐Ÿ”Œ Power supply: Use the original adapter (e.g. for Xiaomi) 11T Pro needs a block on 120W). Cheap charging can give unstable voltage.
  • ๐Ÿ”‹ Battery: If the phone turns off at 30-40% charge, the battery is worn out.
  • โšก Cable: Damaged USB-C cables often cause voltage drawdowns. Try another cable (preferably with support) USB 3.1).
  • ๐Ÿ”„ Wireless charging: on models with support for Qi (for example, Xiaomi 13 Pro) ripples may appear due to incompatibility with the charging station.

A critical sign of power problems is that the ripples are synchronized with the charging indicator (e.g., flicker increases when a cable is connected/disconnected). In this case, first check the contacts of the USB-C connector for oxidation or debris.

If the ripples only appear when charging, try to turn on the aircraft mode and connect the charge. If the problem disappears, the conflict between the communication module and the power controller (often found on the Redmi 9A and POCO M3) is to blame.

5. Features AMOLED-screen: PWM-burnout

Devices with AMOLED-matrices (Xiaomi) 12S, Black Shark 5, Redmi K60) technology PWM-It's a lighting fixture, and it's a low-brightness fixture. <50%) screen starts to flicker with frequency 200โ€“250 Hz, which is perceived as ripples. It's not a breakdown, it's a feature of the technology, but it can be reduced:

  • ๐ŸŒ“ Set the brightness level. >60% - for the most part AMOLED-Xiaomi screens PWM shut down.
  • ๐Ÿ”„ Turn it on. DC-Mode (if available) in developer settings (Settings) โ†’ The phone. โ†’ Version. MIUI โ€” Tap 7 times, then return to the Additional Settings โ†’ Developer parameters โ†’ DC-regime).
  • ๐ŸŽจ Use dark themes on a black background PWM less visible.

Another problem with AMOLED is pixel burnout, and if there's a constant ripple from icons or navigation bars, the matrix has degraded, and that's incorrigible, but you can slow down the process.

  • Turn off static interface elements (such as navigation bar).
  • Reduce the screen fade time to 15 seconds.
  • Use apps like Screen Balance to cycle colors.

๐Ÿ’ก

On Xiaomi 13 Ultra and MIX Fold 3, ripples on AMOLED can be associated with a bug in the LTPO 3.0 driver. Updating to MIUI 15.0.4+ solves the problem 90% of the time.

External factors: magnetic fields, temperatures and humidity

Screen ripples can be caused by external conditions that users often overlook:

  • ๐Ÿงฒ Magnetic fields: If the phone is lying next to a speaker, wireless charging or microwave, the screen can flicker).
  • โ„๏ธ Low temperatures: at <0ยฐC liquid crystal matrixes (e.g., in Redmi) A2+) They lose their responsiveness, which manifests as ripples.
  • ๐Ÿ’ฆ Humidity: Condensation inside the enclosure (for example, after a bath) can cause short circuits in the plume.
  • โ˜€๏ธ Direct sunlight: on some Xiaomi TVs (e.g. Mi) TV P1) The ripples appear due to overheating of the matrix.

Checking for external factors is simple: move the device to another place. If the ripples are gone, look for the source of interference. For example, Xiaomi 50W wireless charging sometimes causes interference if the phone is lying on them at an angle.

7.Diagnostics and repair: when to contact the service

If you've exhausted all the software methods and the ripples are left, it's time to get ready for repairs.

Backup data (ripples may be a sign of the imminent death of the matrix)|Record a video showing the problem (helps the master)|Check warranty (on models up to 2023 can operate extended warranty on the display)|Clarify the cost of spare parts (for example, the matrix for Xiaomi 13 Lite is worth it). ~8000 โ‚ฝ)|Find reviews about the service center (especially if itโ€™s not the official Xiaomi)

The cost of repair depends on the model and type of malfunction:

  • Replacement of plume: 500โ€“2000 โ‚ฝ.
  • Replacement of the matrix: 3000โ€“15000 โ‚ฝ (Xiaomi MIX 4 with a subscreen camera โ€“ up to 20,000 โ‚ฝ).
  • Board repair (display controller): 2000โ€“10000 โ‚ฝ.

โš ๏ธ Note: On Xiaomi TVs (e.g. Mi) TV A2 43) The ripples are often due to a malfunction of the power supply, not the matrix. The wizards often suggest replacing the screen, although the problem is solved by replacing the capacitors in the PD (cost). ~1500 โ‚ฝ). Always require a detailed diagnosis!

FAQ: Frequent questions about ripples on Xiaomi screens

Could ripples on Xiaomiโ€™s screen appear because of a virus?
Theoretically, yes, but extremely unlikely. Viruses can affect graphical rendering (for example, through vulnerabilities in SurfaceFlinger), but usually this manifests as artifacts in the interface, rather than as uniform ripples. If you suspect a virus: Install Malwarebytes and scan the system. Check the application rights in Settings โ†’ Annexes โ†’ Permits (Look for programs with access to the software) android.permission.WRITE_SECURE_SETTINGS). Drop your phone to factory settings (be sure to back up) If there's a ripple left, it's not the virus that's the problem.
Why is the screen on Xiaomi only ripped in some apps (like TikTok or YouTube)?
This is a typical conflict between screen refresh rates and FPS content. For example: YouTube videos with a resolution of 1440p60 on a screen with 90 Hz can cause ripples due to frame mismatch. At TikTok, the problem is often associated with aggressive optimization of videos for weak devices (for example, Redmi 9C). Solution: On YouTube, disable Adaptive frequency in the application settings. At TikTok: limit FPS through the developer settings (Limit background processes โ†’ 2 process).
On a Xiaomi TV, the screen ripples when viewed via HDMI.
The problem is typical for Mi models TV Q1E Redmi Smart TV Reasons: Permission incompatibility: TV tries to scale signal with 1080p before 4K. Problems with HDMI-Cable: Cheap cables are not supported HDMI 2.1. Settings HDR: switched on HDR It's rippling at an incompatible source. Solution: Settings. TV โ†’ Image: โ†’ Regime. HDMI โ†’ Install "PC" or "Game" Source settings (e.g., consoles) โ†’ Turn it off. HDR And Dolby Vision Replace HDMI-Cable certified (e.g. Xiaomi) HDMI 2.1)
After the phone crashed, Xiaomi got ripples. Can you fix it yourself?
If the ripples have been caused by physical impact (fall, impact), self-repair is not recommended, most likely damaged: Display plume (cracks, tears), Matrix (microcracks in the backlight), Contacts on the motherboard, what can be done before visiting the service: Check if the plume is moving away: gently press the top of the screen (near the front camera). If the ripples change, the plume has gone away. Connect the phone to an external monitor through the front camera. USB-C โ†’ HDMI. If the monitor is stable, the problem is in the phone display. โš ๏ธ Note: On models with curved screens (Xiaomi 11 Ultra, MIX (4) self-disassembly almost always results in damage to the display. The plumes are brittle and are glued to the frame.
How to turn off PWM on Xiaomi to remove ripples?
Shut it down completely. PWM on AMOLED-Xiaomi screens are not allowed, but you can minimize its impact: Increase the brightness to 60-70% - at this level PWM shut down or operate at a high frequency (>500 Hz. Activate. DC-Mode (if available): Settings โ†’ The phone. โ†’ Version. MIUI (tap 7 times) โ†’ Developer parameters โ†’ DC-Use dark themes -- black background. PWM Install a custom core (e.g., FrancoKernel) with PWM-free (requires unlocking the bootloader). On some models (Xiaomi 12 Pro, 13 Ultra) ripples PWM You can reduce it via the engineering menu: ##36446337## โ†’ Test Menu โ†’ Display โ†’ PWM But be careful โ€“ incorrect settings can lead to a burnout matrix.
