The screen refresh rate (hertz) directly affects the smoothness of the image, the responsiveness of the interface and even the autonomy of the device. On Xiaomi smartphones and TVs, this parameter can be changed both through standard MIUI settings and with the help of hidden features or developer tools. However, not all models support high values – for example, 120 Hz or 144 Hz – and some require unlocking additional options.
In this article, we will analyze all available ways to change the hertz: from the basic settings in the display menu to use. ADB-Special attention will be paid to the nuances for popular models - Redmi Note 12 Pro+, POCO F5, Xiaomi 13T and Mi TVs. TV Q2. We also explain why some devices have a gray option and how to activate it.
What Xiaomi devices support the Hertz change
Not all Xiaomi gadgets allow you to manually switch the screen refresh rate.
- 📱 Smartphones: only models with AMOLED- or LCD-screens supporting 90 Hz+ (For example, the Redmi Note series. 11/12 Pro, POCO F4/F5, Xiaomi 12/13). Budgetary devices (e.g. Redmi) 10A) usually fixed 60 Hz.
- 📺 Televisions: models with markings 120Hz in characteristics (Mi) TV Q2 75", Redmi Smart TV X55). There is no option on 60 Hz panels.
- 🖥️ Tablets: Xiaomi Pad 5/6 support 120 Hz, but the setting can be hidden in the developer.
To check the maximum hertz of your device, go to Settings → About Phone → All specs → Display. If it says 60Hz, there are no other hardware modes. If 90Hz/120Hz/144Hz, but the option is inactive, the problem is firmware or regional restrictions.
| Model of the device | Max. Hertzovka. | Does it support manual switching? | Whether ADB is required |
|---|---|---|---|
| Redmi Note 12 Pro+ | 120 Hz | Yeah (in display settings) | No. |
| POCO F5 | 120 Hz | Yes (with restrictions in some regions) | Sometimes. |
| Xiaomi 13 Ultra | 120 Hz | Yes (with adaptive mode) | No. |
| Mi TV Q2 65" | 120 Hz | Yes (in image settings) | No. |
| Redmi 10C | 60 Hz | No. | — |
⚠️ Note: On certain devices (e.g, POCO X3 Pro) 120 Hz may be blocked due to overheating, in which case forced activation via ADB will result in automatic rollback up to 60 Hz under load.
Method 1: Change the hertz through standard MIUI settings
The easiest method is to use the built-in system options, which is suitable for most modern Xiaomi smartphones (starting with MIUI 12) and TVs.
For smartphones:
- Open the Settings → Display.
- Select the screen refresh rate (may be called Adaptive Frequency or Update Mode).
- Choose one of the available values: 60 Hz, 90 Hz, 120 Hz or Auto (adaptive mode).
For Mi TVs:
- Go to Settings → Image → Additional.
- Find the option of Update Frequency or Motion Clarity.
- Select 120Hz (if available). Some models will require Game Mode to be enabled.
☑️ Preparation for Hertzovka change
If the option is grey and inactive, it could mean:
- 🔋 Battery Saving Mode is enabled (turn it off in Settings) → Battery).
- 🌍 The device works in a "global" firmware with restrictions (you need to switch to the "global" firmware). EEA china ROM).
- 🔧 Requires unlocking through ADB (see next section).
Method 2: Unlock hidden modes through ADB
If the standard settings don't allow you to change the hertz, you can use the developer tools, which works on most Xiaomi devices, but requires a connection to a computer.
You'll need:
- 💻 Computer with installed Xiaomi and Platform Tools drivers (ADB).
- 📱 Included debugging by USB (Settings → The phone. → Version. MIUI — Press 7 times, then return to Additional → For developers).
- 🔌 USB-Type C Cable (preferably original).
Step-by-step:
- Connect your smartphone to your PC and confirm the debugging permission.
- Open the command prompt (cmd) in the folder with ADB.
- Enter the command to check the connection: adb devices must appear serial number of the device.
- Unlock hidden hertz settings: adb shell settings put global force_high_refresh_rate 1 For Mi TVs, TV Use adb shell setprop persist.sys.fps 120
- Restart the device. After that, additional options will appear in the display settings.
⚠️ Note: On some devices (e.g. Redmi) K50) forced inclusion 120 Hz through ADB If the screen starts to flicker, return the settings with the command: adb shell settings put global. force_high_refresh_rate 0
What if the ADB can’t see the device?
Method 3: Using Third-Party Applications
If you don't want to mess with ADB, you can try specialized utilities. They're suitable for devices with unlocked bootloader or root rights.
Popular applications:
- 📱 SetEdit allows you to edit system settings, including hertz. Requires root.
- 🖥️ QuickSwitch – switches the refresh rate through the notification panel (works on some Xiaomi.eu firmware).
- 🔧 MIUI Hidden Settings – reveals hidden options MIUI without ADB (not always stable).
Example of settings via SetEdit:
- Install the application from 4PDA (registration required).
- Open the System section → display_refresh_rate.
- Change the value to the desired frequency (for example, 120).
- Save and restart the device.
💡
Before using third-party apps, check the reviews on the forums – some utilities may contain advertising software or work incorrectly with the latest versions of MIUI.
On Xiaomi TVs, third-party apps to change the hertz do not work – only standard settings or ADB.
Method 4: Firmware of the custom core or MIUI-port
For those who are willing to take risks, there is a radical method, which is to install a modified firmware, which will not only unlock the hertz, but also provide additional features.
Popular firmware for Xiaomi:
- 📱 Xiaomi.eu – official firmware without restrictions (supports 120 Hz on all compatible models).
- 🔧 Pixel Experience – ported Android with hertz settings like on Google Pixel.
- 🚀 LineageOS - custom open source firmware (requires root).
Instructions for installing Xiaomi.eu:
- Unlock the bootloader through the Mi Unlock Tool (can take up to 72 hours).
- Download the firmware for your model from Xiaomi.eu.
- Install it via TWRP or Fastboot (instructions are available on 4PDA).
- After installation in the display settings, all available hertz modes will appear.
⚠️ Note: Installing custom firmware will void the warranty and may result in a brick device. TWRP Mi Flash.
Problems and Solutions in Changing Hertzov
Even after you successfully change the refresh rate, you may experience side effects, and here are the most common ones and ways to address them:
| Problem. | Possible cause | Decision |
|---|---|---|
| The screen flickers or slows down | Incompatibility of the display driver with the selected hertzovka | Return 60Hz or update the firmware |
| The battery goes down fast. | 120 Hz Increases Energy Efficiency by 15–25% | Use Adaptive Mode or Disable 120Hz in the Background |
| Option of gray color after rebooting | Resetting MIUI settings or system update | Re-unblocking through ADB |
| Apps do not support high hertz | Developer restrictions (e.g. on Netflix or YouTube) | Use it. ADB Adb shell settings put global settings force_fps 1 |
If after changing the hertzov device began to overheat, check:
- 🔥 Running background processes (open Settings) → Annexes → Launched).
- 🎮 Game performance mode (the Game Turbo can be forced to turn on 120 Hz).
- 🔄 System updates (in new versions) MIUI Often fix bugs with hertz).
💡
Adaptive Mode (Auto) is the optimal balance between smoothness and autonomy, and it automatically reduces the hertz when watching video or reading, increasing it in games and interfaces.
How to Check the Real Screen Hertz
Sometimes the system shows one value and the actual refresh rate is another. To make sure that changes are applied, use specialized tests.
Methods of verification:
- 📱 Display Tester app (available on Google Play) shows current hertz and supported modes.
