Step 2: Execution of commands
Open the command line (or Terminal) and type:
adb devicesIf the device is determined (its serial number will appear), execute the command to unlock 120 Hz:
adb shell settings put global peak_refresh_rate 120To apply the changes, restart the smartphone:
adb shell rebootStep 3. Checking.
After the reboot, check the screen frequency using the Refresh Rate Test app (available on Google Play).If the value hasn't changed, try an alternative command:
adb shell settings put global min_refresh_rate 120
adb shell settings put global peak_refresh_rate 120⚠️ Note: Some Xiaomi firmware after commands ADB The frequency is reset to 60 Hz when the screen is locked. To fix the settings, you may need a modified firmware or Magisk module.

|---|---|---|
| peak_refresh_rate 120 | Set the maximum frequency | It works in most applications, but can be reset |
| min_refresh_rate 120 | Set a minimum frequency | Forced 120Hz everywhere (heavy battery drain) |
| force_fps 1 | Includes the forced frequency | Could cause artifacts in games |
💡
If the frequency is reset after ADB commands, try disabling the Adaptive refresh rate function in the display settings (if any).
