How to increase the screen frequency on Xiaomi: from 60 Hz to 120+ Hz

The smoothness of animations, scrolling clarity and responsiveness of the interface all depend on the frequency of screen refresh. Xiaomi smartphones of the latest generation support high frequencies (90 Hz, 120 Hz, 144 Hz), but not always these modes are available out of the box. Why is this happening? It is about the balance between performance, autonomy and heat. The manufacturer often limits the maximum default frequency to extend battery life.

In this article, we’ll look at all the ways to increase screen frequency on Xiaomi, Redmi and POCO devices, from official MIUI settings to hidden engineering menus. You’ll learn how to turn on 120Hz on models where this option is locked, what apps will help you get around the restrictions, and what to do if the screen starts to “brake” or quickly dies.

⚠️ Important: Not all Xiaomi smartphones support high frequencies. If your model is initially designed for only 60 Hz, artificial boosting can cause image artifacts, overheating or even a matrix failure. Check the specifications of your device before experimenting!

1. Check the current screen frequency

Before you try to increase the frequency, make sure your smartphone supports modes above 60Hz at all.

1. Open Settings → About the phone and find a model of the device. Check it against the official specifications on the Xiaomi website.
2. Use third-party apps like Display Tester (available on Google Play) to measure the actual refresh rate.
3. Check if you have the option in the menu: Settings → Display → Screen refresh rate. If it is not available, your device either does not support high frequencies or the option is hidden.

For example, the Xiaomi 12 Pro and POCO F4 GT have matrices with support for 120 Hz, and the Redmi Note 10 – only 90 Hz. Outdated models like the Redmi 8 are limited to 60 Hz at the hardware level.

2.Official method: setting up in MIUI

If your smartphone supports high frequencies, the easiest way to turn them on is through standard MIUI settings:

1. Go to Settings → Display.
2. Select the screen refresh rate (some firmware may call it "Adaptive Frequency").
3. Set the desired value: 60 Hz, 90 Hz, 120 Hz or Auto (adaptive mode).

Some models (such as Xiaomi 13 Ultra) have Dynamic Switch mode, which automatically adjusts the frequency to the content: 1 Hz for static images and up to 120 Hz for games or scrolling.

⚠️ Note: Some firmware may be obscured due to regional restrictions, such as European versions. POCO X3 Pros have a locked 120Hz mode, although the hardware supports it, in which case it will help to change the region or manually edit settings (more about this below).

3. Hidden settings: engineering menu and ADB-team

If the standard settings do not have the option to change the frequency, you can unlock it through the engineering menu or ADB (Android Debug Bridge), which are suitable for advanced users and require caution!

Method 1: Engineering Menu (Qualcomm only)

On smartphones with Qualcomm processors (most models) Xiaomi/Redmi/POCO) You can use a hidden menu:

1. Open the Phone app and enter the code: ##4636##.
2. In the menu that opens, select Testing → Display.
3. Find the Refresh Rate and set the desired value.

⚠️ Warning: Not all options in the engineering menu are safe, changing the options you don't understand can cause your screen or camera to crash!

Method 2: ADB-commands (universal method)

For this method, you will need a computer with ADB drivers installed and USB debugging enabled on your smartphone:

1. Connect the phone to the PC and open the command line (cmd).
2. Enter the command to check the current frequency: adb shell dumpsys display | grep "refresh rate"
3. To set a fixed frequency (for example, 90 Hz), use: adb shell settings put global peak_refresh_rate 90 For 120 Hz replace 90 on 120.
4. Adaptive Mode: Adb shell settings put global adaptive_refresh_rate_enabled 1

Critical information: On some firmware after use ADB-The frequency is reset after the restart. To fix the changes, you may need to edit the system files (requires root rights).

4. Applications for Forced Frequency Increase

If standard methods don’t work, you can use third-party utilities that don’t guarantee 100% results, but often help unlock hidden options.

• 📱 SetEdit allows you to edit system settings, including screen frequency.
• 🔧 Refresh Rate Changer is a simple utility for changing the frequency without root (does not work on all models).
• 🛠️ MIUI Hidden Settings – reveals hidden options MIUI, including display settings.

⚠️ Note: Applications from unverified sources may contain malicious code. APK Only from official sites or Google Play. Also remember that forced frequency change can lead to a high frequency:

• Increased battery consumption (15-30% faster).
• Overheating of the processor with a long load.
• Image artifacts (flickering, stripes) on uncertified matrices.

5. Problems after frequency change and their solution

After manually increasing the frequency, users often experience side effects, and consider the typical problems and ways to fix them:

If after the changes, the smartphone began to "lay down" or artifacts come out, return the standard settings.

1. Go to Settings → Display and select 60Hz.
2. Or do a reset through ADB: adb shell settings delete global peak_refresh_rate

💡

If after increasing the frequency, the screen began to “twitch” when scrolling, try to turn off animations in the developer settings (Settings → About the phone → MIUI version – tap 7 times, then Settings → Additional → For developers → Animation scale).

6. Performance optimization for high frequencies

To make 90 Hz or 120 Hz work consistently, you need to make sure that the smartphone does not "brake" due to background or overheating.

• 🔄 Turn off background processes: Go to Settings → Annexes → Autostart and ban the autostart of unnecessary programs.
• ⚡ Activate Performance Mode: In Settings → Battery → Select "Performance" (increases heat but reduces lags).
• 🧊 Control the temperature: Use applications like CPU Monitor to track overheating. At 50°C+ frequency may automatically decrease.
• 🎮 Settings for games: In Game Turbo (Settings) → Special facilities → Game Turbo) Enable the option "High frame rate".

Models with Snapdragon 8 Gen 2 processor (such as Xiaomi 13 Pro) support Q-Sync technology, which synchronizes the screen frequency with FPS in games, to activate it:

1. Install the latest version of MIUI.
2. Turn on 120Hz in the display settings.
3. In Game Turbo, select Esports mode.

💡

On smartphones with AMOLED-screens (e.g. Xiaomi) 12T Pro) high frequencies are less critical for autonomy than on LCD. This is due to the peculiarities of technology: pixels on the AMOLED only consume energy when displaying white/light content.

7. Xiaomi models with support for high frequencies (2022–2026)

Not all Xiaomi devices support frequencies above 60 Hz. In the table below are current models (for 2026) indicating the maximum refresh rate of the screen:

⚠️ Note: Some models (e.g. Redmi Note 11 Pro) only have 120Hz on Chinese firmware. European versions may require firmware re-flashing, which voids warranty.
