How to change the hertzok (screen refresh rate) on Xiaomi phone: all ways

Screen refresh rate (hertz) is a key parameter that affects picture smoothness, battery life and even eye comfort. Xiaomi’s latest generation smartphones (from Redmi Note 10 to Xiaomi 14 Ultra) support dynamic Hz change from a frugal 60 Hz to a gaming 144 Hz. But the system does not always choose the optimal mode automatically. In this article, we will analyze all working methods for manually adjusting hertz, including hidden MIUI functions and tools for advanced users.

It’s important to understand that not all Xiaomi models allow you to change the frequency manually. For example, budget devices (Redmi A2, POCO C50) are often limited to 60 Hz at the hardware level. and flagships (Xiaomi 13T Pro, Black Shark 5) can offer up to 5 modes — from 48 Hz for reading to 120+ Hz for gaming. We collected current data for MIUI 14/15 and firmware based on Android 13/14.

1. Check the current screen hertzing

Before you change your settings, make sure your Xiaomi does support the frequency change.

• 🔍 Use the app. CPU-Z (Display section – show current Hz and maximum possible.
• 📱 Put the debugging on. USB and connect to the PC: the adb shell dumpsys display command will display detailed information about the screen.
• 🎮 Run the Game Turbo test (if any): some models show FPS and Hz in real time.

Please note: AMOLED-screens (e.g. Xiaomi) 12 Pro) the frequency can change dynamically even without your intervention -- that's normal. IPS-matrices (Redmi Note) 11) fixed-value: 60/90/120 Hz.

2. Change the hertz through the standard MIUI settings

The easiest way is to use the built-in system options. The interface may vary slightly depending on the version of MIUI, but the general logic is maintained:

1. Open the Settings → Display.
2. Select the screen refresh rate (or Adaptive frequency on new models).
3. Available options: 🔄 Auto – the system selects Hz based on content (recommended for most users). 📱 60 Hz – Minimum power consumption, suitable for reading and office tasks. 🎮 90/120/144 Hz - for games and scrolling the tape of social networks.

On some models (e.g. POCO F5), the option is hidden behind the optional menu: Settings → Additional → Function Lab. If there is no item at all, your smartphone does not support manual configuration (see compatibility table below).

3. Compatibility of Xiaomi models with manual Hz setting

Not all Xiaomi devices allow you to change the hertzovka. Below is the current table for popular models (data for 2026):

If your model isn't in the table, check the specifications on Xiaomi's official website or in the Mi Community app.For example, the 4/5 Black Shark Series supports 144Hz, but the setup is only available through game mode.

⚠️ Note: On devices with MediaTek Helio G (e.g., Redmi Note 11) forced on 90+ Hz can cause overheating and reduce battery life by 20-30%.

4. Change of hertz through the engineering menu (for experienced)

If the standard settings don’t provide the right options, you can try the engineering menu, which works on most Xiaomi with Qualcomm Snapdragon processors, but you need to be careful:

1. Open the Phone app and enter the code: ##4636##.
2. Select Testing → Display.
3. Find the Refresh Rate and set the desired value.

On some firmware (for example, MIUI EU) The engineering menu is blocked. The alternative is to use ADB-team:

adb shell settings put global peak_refresh_rate 120.0


adb shell settings put global min_refresh_rate 60.0

Team team. peak_refresh_rate It sets the maximum number of stains, and min_refresh_rate — After you do it, reboot the device.

5. Set up hertz for individual applications

MIUI 14/15 allows you to assign different refresh rates to different applications, which is useful if you want to save battery in messengers, but get the most smoothness in games.

1. Go to Settings → Applications → Application Management.
2. Select the app you want (like PUBG Mobile or Chrome).
3. Press the screen refresh rate and set the value: 📖 For the readers (Moon)+ Reader - 60 Hz. 🎥 For video (YouTube, TikTok) - 90 Hz. 🎮 For games (Genshin Impact, Call of Duty) – 120 Hz.

This feature is not available on all devices, and if you don't have an option, try enabling it through the MIUI Lab:

1. Activate Developer Mode (7 times click on the MIUI version in Settings → About Phone).
2. Go back to Settings → Additional → Functions Lab.
3. Turn on the Personalized refresh rate switch.

If after the changes the smartphone began to slow down, reset the display settings:

1. Go to Settings → System → Resetting settings.
2. Select Reset Display settings (does not affect user data).

⚠️ Attention: On devices with LPDDR4X memory (e.g. Xiaomi) 11T Pro) forced inclusion of 120 Hz in games may cause friezes due to bandwidth limitations RAM. In such cases, it is better to use 90 Hz.

7. Alternative methods: Magisk and custom firmware

For advanced users willing to sacrifice the warranty, there are radical ways to disperse (or vice versa, limit) the hertzovka:

• 🛠️ Magisk Refresh Rate Changer – allows you to set any Hz values, even not supported by iron (risk of screen damage!).
• 📲 LineageOS, Pixel Experience – often offer flexible display settings but require unlocked bootloader.
• 🔧 Change build.prop: Adding a line ro.sf.lcd_density=440 and persist.vendor.sy.display.refresh=120 Can unlock hidden modes (for experienced ones only!).

Before using these methods:

1. Make a full backup through TWRP.
2. Check the compatibility of the module with your model on the XDA Developers forum.
3. Note that informal changes can lead to brick (turning your phone into a brick).

💡

Using Magisk or custom firmware voids Xiaomi’s warranty, which is only suitable for devices that are out of warranty or for advanced users.
