How to Change the Screen Update Rate on Xiaomi: A Complete Guide (2026)

Why screen refresh rate is important for your Xiaomi

The screen refresh rate is a parameter that determines how many times a second the picture on the display is updated. Measured in hertz (Hz): standard 60 Hz, smooth 90 Hz or ultrasmooth 120 Hz. On Xiaomi, Redmi and POCO smartphones, this parameter can be changed manually, which directly affects the responsiveness of the interface, smooth animations and even battery life.

If you notice that the screen twitches when you scrolle, the lag'yat games, or the battery goes down too quickly, maybe the problem lies in the wrong frequency. For example, 120 Hz gives incredible smoothness, but increases the load on the processor and battery. And 60 Hz saves charge, but can seem "brake-down" after getting used to high values. In this article, we will discuss how to find the optimal balance for your model.

It is important to understand that not all Xiaomi devices support high frequencies. For example, the budget models Redmi 10A or POCO M4 Pro are limited to 60 Hz, while flagships like Xiaomi 14 Ultra or Black Shark 6 Pro offer up to 144 Hz. Check the maximum possible frequency for your model can be in the specifications on the official website or through the CPU-Z application.

What Xiaomi models support changing the screen frequency

The ability to change the refresh rate of the screen depends on the hardware stuffing of the smartphone. Here are the key series of Xiaomi devices where this feature is available:

• 📱 Flagship series: Xiaomi 12/13/14, Mi 10/11, Mix 4/Fold — support 90–120 Hz, some models up to 144 Hz.
• 🎮 Gaming smartphones: Black Shark 4/5/6 — before 144 Hz with the ability to fine tune for games.
• 💰 Mid-segment: Redmi Note 11/12 Pro+, POCO F4/F5 — usually 90 or 120 Hz.
• 🔋 Budget models: Redmi 10/12, POCO M5 — most often fixed 60 Hz.

To find out exactly if your Xiaomi supports frequency change, check out:

1. Technical specifications on the site mi.com (enter the model in the search).
2. Display settings: If the menu has a screen refresh rate, then the function is available.
3. Apps like DevCheck or AIDA64 are the ones that show the maximum frequency they support.

⚠️ Note: On some models (e.g, POCO X3 NFC) 120Hz is only available when the bootloader is unlocked and custom firmware is installed. Officially, the manufacturer can limit this parameter.

Where is the screen frequency setting in MIUI?

Depending on the version of MIUI (Android shells from Xiaomi), the path to settings may be slightly different. Here are the current instructions for the latest versions (MIUI 14/15):

Method 1: Through the main display settings

1. Open Settings (the gear icon on the desktop).
2. Go to the Screen section (or the Display in some firmware).
3. Find the screen refresh rate (may be called Refresh rate in English firmware).
4. Choose one of the available values: 60 Hz, 90 Hz, 120 Hz or Adaptive.

Method 2: Through additional settings (for some models)

On devices with AMOLED-screens (for example, Xiaomi 13 Pro) setting can hide deeper:

Settings → Display → Additional settings → Update frequency

Make sure you have the latest version of MIUI.

Restart your smartphone if the item is not on the menu

Check if the item is hidden behind "Advanced settings"

Update the firmware through Settings → About the phone → System update-->

If you don't find this, maybe your model doesn't support frequency change, or the function is blocked by the manufacturer, and then you can try alternative methods (we'll talk about them later).

How to enable adaptive refresh rate on Xiaomi

Adaptive frequency is a mode in which the smartphone automatically adjusts the refresh rate of the screen depending on the content.

• 📄 When reading text or viewing a photo – 60 Hz (battery savings).
• 🎮 In games or when scrolling the tape — 90/120 Hz (smoothness).
• 📺 When watching video, the frequency is synchronized with FPS content.

To activate this mode:

1. Go to Settings → Screen → Screen refresh rate.
2. Select the Adaptive (or Auto-Select) option.
3. In some firmware (for example, on POCO F5) you need to additionally enable the option Adaptive Synchronization in the same menu.

Adaptive mode is especially useful for users who want to save battery power but are not willing to sacrifice smoothness in games or social networks. However, note that on some models (for example, the Redmi Note 11 Pro+), the adaptive frequency does not work perfectly and can cause microstuttering when switching.

💡

If the adaptive mode is not stable, try manually setting a fixed frequency (e.g. 90Hz) – this often gives a more predictable result.

How to change the screen frequency through the engineering menu (for advanced ones)

If standard settings don't provide the right options, you can try changing the frequency through the engineering menu, which is suitable for power users and can cause failures if you do something wrong!

Instructions for devices on Qualcomm Snapdragon processors:

1. Open the Phone app and enter the code: ##4636##.
2. In the menu that appears, select Hardware Testing (or Hardware Testing).
3. Find the Display or Screen section.
4. Try changing the Refresh Rate option (if available).

For devices on MediaTek (e.g. Redmi Note 12):

1. Enter the code: ##36446337##.
2. Go to Hardware Testing → Display.
3. Try changing the Screen Refresh Rate.

⚠️ Warning: Changing the settings in the engineering menu can lead to unstable screen performance, artifacts or even overheating.If after the changes the screen begins to flicker or "glut", immediately return the standard settings or reset via Settings. → System system → Resetting settings.

How to check the actual screen refresh rate

Sometimes the frequency you select doesn't match the real one, and it can be because of:

• 🔋 Battery savings (MIUI automatically lowers the frequency at low charge).
• 📱 Restrictions of a particular app (e.g. YouTube or Netflix can block high frequencies).
• 🐞 Software bugs in firmware.

To find out the real frequency, use specialized applications:

If the app shows a frequency below the set frequency (for example, 60 Hz instead of 120 Hz), try:

• Reboot the smartphone.
• Turn off the power saving mode in the Settings → Battery.
• Update the firmware to the latest version.

Frequent problems and their solutions

When changing the refresh rate of the screen, Xiaomi users often face problems.

Problem 1: No item "Update frequency" in the settings

Possible causes and solutions:

• 📱 Outdated firmware: Update MIUI through settings → The phone. → Updating the system.
• 🔒 Region constraint: Some features are hidden in global firmware. Try switching to EEA china ROM (riskyly!).
• 🛠️ Hardware limitation: Budget models (e.g. Redmi) 9A) They do not physically support high frequencies.

Problem 2: The screen flickers or twitches after a change in frequency

This may be due to:

• 🔌 Shell conflict: Try turning off animations in Settings → Special facilities → Delete animations.
• 🎨 Incompatibility with theme: Return the standard theme MIUI In Settings → Theme.
• 🐛 Firmware bugs: rollback to the previous version MIUI Sometimes it helps (instructions on the forums) 4PDA or XDA).

Problem 3: Battery goes down quickly at high frequencies

Solutions for saving charge:

• 🔋 Use Adaptive Mode instead of a fixed 120Hz.
• ⚡ Turn off high frequencies for individual applications through Settings → Annexes → Battery management → Choice of applications.
• 🌙 Activate the dark theme - on AMOLED-This reduces the power consumption of screens.

💡

If the frequency changes, the smartphone starts to warm or slow down, return the standard settings. High frequencies require more resources, and weak processors (for example, in the Redmi Note 10) may not cope.
