How to turn on the hertzovka (screen refresh rate) on Xiaomi phone: the complete guide

Screen refresh rate (hertz) is one of the key parameters that affect the smoothness of the picture and responsiveness of the smartphone. Xiaomi, Redmi and POCO smartphones of the latest generations support increased frequencies - 90 Hz, 120 Hz or even 144 Hz, but by default they are often turned off to save battery power. In this article, we will discuss how to properly activate the high hertz, which models support the function, and what to do if the option is not available in the settings.

It’s important to understand that not all Xiaomi devices support dynamic frequency change. For example, the budget models Redmi Note 11 or POCO M4 Pro have a fixed 60 Hz or 90 Hz, while flagships like Xiaomi 13 Ultra or Black Shark 5 Pro offer adaptive modes up to 144 Hz. It is also worth considering that high frequency increases the load on the processor and reduces battery life – so the manufacturer sometimes hides the setting behind additional conditions.

If you’re not sure if your model supports high hertz, check the specifications on Xiaomi’s official website or use apps like AIDA64 or CPU-Z. In this article, we’ll look at all possible ways to enable it, from standard MIUI settings to hidden engineering menus.

Which Xiaomi models support high hertz (90/120/144 Hz)?

Before you try to enable a high refresh rate, make sure your device supports it. Below is the current list of Xiaomi, Redmi and POCO models with support for 90 Hz+ (data for 2026):

If your model isn't in the spreadsheet, it doesn't mean it doesn't support high hertz. For example, some Redmi K-series devices (like the Redmi K60 Pro) also feature 120Hz displays to get an accurate view of your screen's maximum frequency:

• 🔍 Check the official specifications on Xiaomi’s website.
• 📱 Use the DevCheck app (display section).
• 🛠️ Go to the engineering menu (more on that below).

⚠️ Attention: Some models (e.g, POCO X3 Pro) support 120 Hz, but only at resolution FHD+. If you use HD+, frequency automatically decreases to 60 Hz.

Method 1: Enable the hertz through standard MIUI settings

The easiest way to activate a high refresh rate is to use the built-in MIUI settings. The interface may vary slightly depending on the firmware version (MIUI 14 or MIUI 15), but the overall algorithm remains unchanged.

Open the Settings app and go along the way:

Settings → Display → Screen refresh rate

In this menu you will see the available options:

• 🔄 Auto (adaptive frequency, switches between 60 Hz and 120 Hz depending on the content).
• 📱 60 Hz (standard mode, saves battery power).
• ⚡ 90/120/144 Hz (maximum frequency, best smoothness, but faster battery goes down).

Select the mode you want and confirm the changes. If the screen refresh rate option is not on the menu, then:

• Your model doesn't support high hertz.
• The function is blocked by the manufacturer (solution – see hidden methods).
• You have custom firmware installed without Dynamic Refresh Rate (DRR) support.

Method 2: Activate hidden hertz through the engineering menu

If you don’t have a frequency change option in your standard settings, but you’re sure your model supports it (like the Redmi Note 10 Pro or the POCO X3 NFC), you can try turning it on through the engineering menu, which works on most Qualcomm Snapdragon processors.

For this:

1. Open the phone app and enter the combination: ##4636##
2. In the menu that appears, select Testing → Hardware info.
3. Scroll down to the Refresh Rate section and check the available values.
4. If you have a Set refresh rate, select the desired frequency (e.g. 120) and save the changes.

On some devices (e.g. POCO F3), the engineering menu may not show the hertz change option, in which case, try the alternative code:

##36446337##

⚠️ Warning: Changing the settings in the engineering menu can lead to unstable screen operation. If artifacts (flickering, bands) appear after the change of frequency, return the value to 60 Hz or reboot.

Method 3: Enabling Hertz through ADB (for advanced users)

If standard methods don’t work, you can try activating high frequency via Android Debug Bridge (ADB), which is suitable for devices where the option is hidden software (for example, on some Redmi for the European market).

For this you will need:

• 💻 Computer with installed Xiaomi and ADB-tools drivers.
• 📱 Included Debugging by USB on the phone (path: Settings) → The phone. → Version. MIUI → 7 times press to unlock Developer Mode, then Settings → Additionally. → For developers → Debugging by USB).
• 🔌 USB-cable (preferably original).

Follow the instructions:

1. Connect your phone to your PC and open the command prompt (cmd on Windows or Terminal on macOS/Linux).
2. Enter the command to check the connection: adb devices (should appear serial number of your device).
3. Run the command to turn on 120 Hz: adb shell settings put global peak_refresh_rate 120 For 90 Hz use the value 90 instead 120.
4. Reboot your phone: adb reboot

After the reboot, check the frequency in the display settings or through the Refresh Rate Test app from Google Play. If the option never appears, try an alternative command:

adb shell settings put global min_refresh_rate 120

💡

If so, ADB-commands the hertz reset after the restart, create a script in the Tasker or MacroDroid app that will automatically apply the setting when you turn on the phone.

Method 4: Using Third-Party Applications

If you don't want to mess with ADBs or engineering menus, you can try customized apps to manage refresh rates, but beware: many require root rights, and some may contain malicious code.

The most reliable options are:

• 📊 SetEdit allows you to edit system settings, including hertz. Works without root, but requires ADB-access.
• 🔧 Refresh Rate Changer is a simple tool for changing the frequency (root rights are needed).
• 📈 QuickSwitch – Adds tile to the notification bar for quick hertz switching (Xposed Framework or Magisk required).

Example of working with SetEdit:

1. Install the app from Google Play.
2. Connect your phone to your PC and license it through ADB: adb -d shell pm grant by4a.setedit2 android.permission.WRITE_SECURE_SETTINGS
3. Open SetEdit, find the setting peak_refresh_rate and set the right value (90 or 120).
4. Save the changes and restart the device.

⚠️ Note: Apps like Refresh Rate Changer may conflict with system processes MIUI, causing lags or overheating. Before using, back up your data.

Why the Hertzovka is not turned on: common problems and solutions

If you have followed all the instructions but the high frequency has not worked, the reasons may be:

Another common problem is blocking the hertz on custom firmware. If you use an informal version of MIUI (e.g. xiaomi.eu or Pixel Experience), check if it supports Dynamic Refresh Rate. In some builds, this feature needs to be activated manually via the build.prop file.

On devices with a Mediatek processor (such as the Redmi Note 11 or POCO M5), the refresh rate can be blocked at the kernel level, in which case only an official firmware update or root rights can help.

How do you check that the silk is really working?

Many users include high frequency but don't notice the difference. To make sure the screen is actually running at 90Hz or 120Hz, use one of the following methods:

• 📱 Built-in test MIUI: Go to Settings. → Display. → Screen refresh rate and select Smoothness Test (not available on all models).
• 🔍 The Refresh Rate Test app shows the current frequency in real time.
• 🎮 Game Tests: Run a game with high-hertz support (e.g, PUBG Mobile or Call of Duty and turn on the display FPS graphically.
• 📊 ADB-command: adb shell dumpsys display Find the refresh rate line.

Note that some apps (e.g. YouTube or Netflix) force frequency limits to 60Hz to save charge. To avoid this, activate the option to force high frequency (if any) in the display settings.

💡

If tests show that the frequency is unchanged, chances are your device does not hardware support high hertz, or it is blocked by the manufacturer.
