How to put 120 Hz on Xiaomi Redmi Note 10: official and hidden methods

Xiaomi Redmi Note 10 with its own AMOLED-The screen and support for 90 Hz in the standard configuration often raises questions among users: can the display be overclocked to 120 Hz? The answer is ambiguous: officially the manufacturer does not provide such an option, but there are workarounds. In this article, we will analyze all working methods - from standard settings to hidden engineering menus and commands. ADB.

It’s important to understand that screen refresh rates directly affect the battery and heat of the device. Check the firmware version before experimenting (MIUI 12.5+ is recommended) and note that not all Redmi Note 10 modifications (such as the Note 10 Pro or Note 10S) support similar tricks. If your device is not from the base model of Redmi Note 10 (mojito/sunny), some methods may not work.

1. Check the current screen refresh rate

Before you try to turn on 120Hz, make sure your display supports elevated values at all. Even if the settings are 90Hz, the actual frequency may vary.

Use:

• 📱 Built-in Testing: Go to Settings → The phone. → Version. MIUI and tap 7 times on the "kernel" line (you will be notified "you became a developer"). → Additionally. → For developers → Screen refresh rate.
• 🔍 Third-party apps: Install Display Tester or Screen Refresh Rate from Google Play. They will show the current value in real time.
• 🎮 Test through the game: Run any game with high support FPS (For example, Call of Duty Mobile and check the graphics settings – some titles display the current frequency.

💡

If the developer menu does not include the “Screen Update Frequency” option, your Redmi Note 10 model does not support dynamic Hz change at the software level.

Note that even if the app shows 120Hz, it does not guarantee stable performance. On models with a Snapdragon 678 processor (for example, the Indian version of mojito), a frequency above 90Hz can lead to image artifacts.

2.Official method: MIUI settings

The safest method is to use the built-in options. Unfortunately, most versions of the Redmi Note 10 have a maximum value of 90 Hz, but there are nuances:

1. Open the Settings → Display.
2. Select the option “Screen Update Frequency” (if not, see the next section).
3. Try switching between 60Hz and 90Hz. On some firmwares, the 120Hz option appears after the reboot (MIUI bug 13.0.4).

* On MIUI 14, the 120Hz option can appear on devices with a MediaTek Helio G88 processor (Indian version), but it does not work.

3. Acceleration through ADB: step-by-step instructions

If standard settings don’t work, you can try activating 120Hz via the Android Debug Bridge (ADB), which requires you to connect to a PC and turn on the developer mode.

Install Xiaomi drivers on PC| Enable debugging over USB in the developer settings | Download ADB Tools | Connect your phone with the original cable | Make a backup of the data

-->

Follow the instructions:

1. Connect Redmi Note 10 to your computer and confirm debugging permission.
2. Open the command prompt (cmd) in the folder with ADB.
3. Enter the command to check the connection: Adb devices must appear serial number of your device.
4. Execute the command to unlock hidden settings: adb shell settings put global force_high_refresh_rate 1
5. Restart your phone and check for the 120Hz option in Settings → Display.

⚠️ Note: On some firmware teams force_high_refresh_rate If after the reset the screen starts to twitch or graphic artifacts appear, reset the settings with the command: adb shell settings put global force_high_refresh_rate 0

Alternative method (for MIUI 13+):

adb shell settings put global peak_refresh_rate 120


adb shell settings put global min_refresh_rate 120

4. Hidden Engineering Menus: A Risky Method

Xiaomi has hidden service menus that allow you to change the display settings. Danger: incorrect settings can lead to loss of warranty or damage to the matrix.

To get into the engineering menu:

1. Open the phone app.
2. Enter the code ##36446337## (to check the MIUI version and device model).
3. To access the display settings, use: ##225## or ##6484##

In the Display Test or MTK Engineer Mode menu, find the following options:

• 🔧 Refresh Rate: Try to manually set the value of 120.
• 📊 Dynamic Switch: Turn off to record frequency.
• ⚠️ Do not touch, the words TP, LCM or DDIC — Changing these parameters can cause the screen to fail.

⚠️ Warning: If after changes to the engineering menu, the screen stopped responding to touches or vertical bars appeared, immediately reset via Fastboot: fastboot erase frp fastboot reboot This will return the standard settings, but delete all data!

5. Castom firmware: the last option

If none of these methods worked, there is a custom firmware option (such as the Pixel Experience or LineageOS) that often unlocks the hidden capabilities of iron, including 120Hz.

Cons of the method:

• ❌ Loss of official guarantee.
• ❌ Risk of "bricking" of the device.
• ❌ Unstable operation of the camera and sensors.

If you do, follow the algorithm:

1. Unlock the bootloader through Mi Unlock Tool (requires a Xiaomi account binding and wait 7-15 days).
2. Install TWRP Recovery for your model (mojito/sunny).
3. Sweat custom firmware with support for 120 Hz (for example, ArrowOS or HavocOS).

💡

Custom firmware can activate 120Hz, but often breaks the Always-On Display function and degrades autonomy by 20-30%.

Before you run your firmware, check compatibility on the XDA Developers or 4PDA forums. For example, this ArrowOS build with a display overclocking kernel will suit the Redmi Note 10 (mojito).

6.Consequences of acceleration: battery, heating and performance

Increasing the screen refresh rate to 120Hz has the flip side:

Recommendations to reduce negative effects:

• 🔋 Use Adaptive Mode (if available) to automatically decrease frequency when downtime is available.
• ❄️ Turn off 120 Hz in games – modern titles limit themselves FPS energy-saving.
• 🛠️ Install Refresh Rate Changer for flexible Hz management in different scenarios.

On the Redmi Note 10 with a Snapdragon 678 processor with prolonged work at 120 Hz, lags in heavy applications are possible due to insufficient performance GPU Adreno 612 Tests show that the real benefit of overclocking is only noticeable in the 2D-interface (scrolling, animation), while in 3D-The difference between 90 and 120 Hz is minimal.
