How to change the screen hertz on Xiaomi: all the ways for MIUI 14/15

The screen refresh rate (hertz) directly affects the smoothness of animation, interface responsiveness, and even smartphone autonomy. On Xiaomi devices with support for 90 Hz, 120 Hz or 144 Hz, users can manually switch between modes — for example, to save battery or improve the gaming experience.

• 🔋 Budget models: Redmi 10A, POCO M5 — 60 Hz or 90 Hz without manual tuning.
• ⚠️ Exceptions: Some models (such as Xiaomi 12 Lite) have 120Hz, but the option is hidden in the firmware.

For a full list of supported devices, see the table below. If your model isn't there, try the methods in the Hidden Hertz Settings section.

⚠️ Note: On some devices (e.g. Redmi Note 11 Pro)+) 120Hz is only available in regional firmware (India, China) and in global version MIUI option may not be available.

Official method: changing the hertz in the settings of MIUI

If your smartphone supports manual frequency settings, the easiest way is to use a standard menu. MIUI. The instructions are relevant to MIUI 14/15:

3. Choose one of the available values: 🔄 Auto (adaptive frequency if supported). 🐢 60 Hz (battery savings). ⚡ 90/120/144 Hz (maximum smoothness).

If there is no Update Frequency, your model does not support manual configuration (or the option is hidden).

💡 Useful advice: On devices with LTPO-With displays (such as the Xiaomi 13 Ultra), the adaptive mode (Auto) can reduce the frequency to 1 Hz on static images, saving charge.

Hidden settings: how to turn on the hertzovka if there is no option

If there is no option in the Settings → Display menu to change the frequency, try these methods:

1. through the engineering menu (for advanced users)

Some models (such as the POCO X3 Pro or Redmi Note 10 Pro) hide the hertz settings in the engineering menu.

Enter the phone code in the app: ##4636##
