How to change the hertz screen on Xiaomi: all the ways and nuances

Screen refresh rates (hertz) are a key parameter that affects image smoothness, interface responsiveness, and even smartphone autonomy. On Xiaomi devices with 90Hz, 120Hz, or 144Hz support, users can manually switch between modes, but this is not always obvious. In some models, the option is hidden in the depths of MIUI, and on budget devices it may not be at all.

In this article, we will discuss all the current ways to change the hertz on Xiaomi, Redmi and POCO smartphones, from standard settings to hidden commands for developers. Also explain why some devices are not available, and how to get around the restrictions without risking to the system. If you notice that the screen twitches, the battery goes down too quickly or animations slow down, here you will find a solution.

Before you start settings, make sure that your model supports a high refresh rate. For example, Xiaomi 13 Pro and POCO F5 offer up to 120 Hz, and Redmi Note 12 Pro+ – up to 120 Hz with adaptive mode. On budget Redmi 10A or POCO M5, the hertz is fixed at 60 Hz – you can not change it without modifying the firmware.

1.How to check the current screen hertz on Xiaomi

Before you change the settings, it's helpful to know what frequency is in use right now, and MIUI has built-in tools for that, but they're not always accurate. It's better to use third-party apps.

The easiest way is to install DevCheck (available on Google Play). Once you start, go to the Hardware tab and find the Refresh rate bar. Here you will see the current frequency in hertz. Alternatively, the AIDA64 app, where the information you need is in the Display section.

If you prefer to do without third-party software, you can use the developer mode:

1. Open the Settings. → The phone.
2. Tap 7 times on the line MIUI version until the notification appears You became a developer!
3. Return to the main settings menu and select Additional → For developers.
4. Find the option to Show the refresh rate of the screen and activate it.

Now, the top right corner of the screen will show the current hertz in real time, and note that this method does not work on all models — for example, on the POCO X5 Pro, the option is available, and on the Redmi Note 11 it may not be.

💡

If the Hertz option didn't appear after activating the developer mode, try restarting your smartphone. Sometimes the changes only apply after the reboot.

2. Standard method of changing the hertz in MIUI

On most modern Xiaomi smartphones (starting with MIUI 12.5), the refresh rate change option is placed in the basic settings.

Step 1. Open Settings → Display.

Step 2. Slip on the screen refresh rate (on some models it may be called Adaptive frequency or Smooth screen).

Step 3. Select one of the available modes:

• 🔄 Auto – The system automatically selects the frequency depending on the content (recommended for battery saving).
• 📱 60 Hz – standard mode, minimum power consumption.
• ⚡ 90/120/144 Hz - maximum smoothness, but fast battery discharge.

Some devices (such as the Xiaomi 12T or POCO F4 GT) have an adaptive mode that dynamically switches the hertz from 1 Hz (for static images) to 120 Hz (for gaming and scrolling), which is the optimal balance between smoothness and autonomy.

3.Why there is no option to change the hertzovka: possible reasons

If the display settings don't have a refresh rate, there are a few reasons for that.

Reason 1: Hardware limitations

Budget models Xiaomi (for example, Redmi 9A, POCO M3) are equipped with screens with a fixed frequency of 60 Hz. Check this in the characteristics of the device on the official website or in the DevCheck application. If the maximum hertz is 60 Hz, it is impossible to change it without modifying the firmware.

Reason 2: Regional restrictions

On some models (e.g. Xiaomi 11 Lite NE 5G), the option is hidden for certain regions, due to certification or energy optimization, and the solution is to change the firmware region through MIUI bootloader (a risky method, can lead to loss of warranty).

Reason 3: The MIUI update resets the settings

After major system updates (e.g., from MIUI 13 to MIUI 14), some options may disappear.

1. Go to Settings → Display → Additional.
2. Select Reset Display settings.
3. Reboot your smartphone.

4. Hidden ways to change hertzovka (for experienced users)

If the standard method didn't work, you can try alternatives, which require activation of the developer mode or use of the system. ADB-team.

Method 1: Forced Entry through Developer Settings

On some devices (such as the POCO X3 Pro), the option is hidden, but you can unlock it:

1. Activate Developer Mode (as described above).
2. Go to Settings → Additional → For developers.
3. Find the option Minimum screen refresh rate and set the desired value.
4. Accordingly, in the maximum refresh rate of the screen, select the upper limit.

⚠️ Note: Not all models support this method. It works on the Redmi Note 10 Pro, and the Xiaomi Mi 11 Ultra may not be available.

Method 2: Changes to ADB

For advanced users, there's a way to force a hertz through a computer.

• 🖥️ Install ADB and Fastboot Tools on PC.
• 📱 Turn on Debugging. USB developer-setting.
• 🔌 Connecting your smartphone to your computer.

Then enter in the command line:

adb shell settings put global peak_refresh_rate 120


adb shell settings put global min_refresh_rate 60

120 and 60 are the desired values in hertz. After you execute the commands, restart the device.

💡

Using ADB can cause failures if you enter incorrect settings, and it is recommended to back up the data before experiments.

5.The effect of hertzovka on autonomy and performance

High screen refresh rates significantly increase the load on the processor and battery. According to XDA Developers tests, switching from 60 Hz to 120 Hz reduces battery life by 15-25% depending on the model. For example, Xiaomi 12 Pro in 120 Hz mode discharges 20% faster than 60 Hz.

The table below shows the results of testing autonomy on popular models:

To optimize the balance between smoothness and autonomy, it is recommended:

• 🔋 Use Adaptive Mode if it is available.
• 🎮 Turn on 120Hz for games and video only.
• 📱 For everyday tasks (social networks, messengers) 60-90 Hz will be enough.

On the Xiaomi 13 Ultra and POCO F5 Pro, the adaptive mode reduces the hertz to 1 Hz when reading text, saving up to 10% charge per hour.

6. Solving problems with hertzovka (twitching, failures, spontaneous changes)

Sometimes, when the refresh rate changes, artifacts emerge: the screen twitches, the animations slow down, or the hertzel spontaneously resets, and let's look at typical problems and their solutions.

Problem 1: The screen twitches when scrolling

This is typical for devices with AMOLED-displays (e.g., Xiaomi) 12S), High frequency is in conflict with technology LTPO. Decision:

• Turn off the Adaptive Frequency and set a fixed value.
• Update the firmware to the latest version of MIUI.
• Reset the display settings (see Section 3).

Problem 2: Hertzel resets after rebooting

Some models (such as the POCO X4 Pro) do not save settings, due to a mistake in MIUI.

adb shell settings put global peak_refresh_rate 120


adb shell settings put global min_refresh_rate 120

These commands force the frequency to 120 Hz. For a permanent effect, root access or custom firmware will be required.

⚠️ Warning: If the screen starts flashing or bars appear after the changes, return the standard settings immediately.This may indicate that the display drivers are incompatible with the selected frequency.

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

Not all Xiaomi smartphones support a frequency above 60 Hz. In the table below - current models with the maximum hertz and screen type:

On budget models (e.g. Redmi) 12C or POCO M6 Pro) Hertz is limited to 90Hz, but there is no adaptive mode. Flagships (Xiaomi 14, MIX Fold 3 offer LTPO-displays with a dynamic range from 1 Hz to 120 Hz.

Before buying, check for high-frequency support – this affects not only smoothness, but also compatibility with games (for example, Genshin Impact or Call of Duty Mobile are optimized for 90+ Hz).
