How to watch the hertz phone Xiaomi: all the ways for MIUI 12-14

Screen refresh rate (hertz) is a key parameter that affects the smoothness of the display of content on Xiaomi, Redmi and POCO smartphones. It depends on how comfortable it will be to play games, flip through social media feed or watch videos. The manufacturer often hides this setting in deep menus or does not display it at all in the interface, especially on budget models with a fixed frequency of 60 Hz.

In this article, you will find 5 proven ways to find out the current screen hertz on any Xiaomi phone – from flagships with 144 Hz to budgeters with 60 Hz. We will look at both standard methods through MIUI and third-party utilities, including hidden engineering menus. All instructions are relevant for MIUI 12, 13 and 14 based on Android 11-14.

1. Check the hertz through the MIUI settings (official method)

The easiest method is to use built-in options, but it doesn’t work on all models: on budget smartphones (Redmi 9A, POCO M3), the item may be missing, and on flagships (Xiaomi 13 Ultra, Black Shark 5), it is usually available.

Instructions:

• 📱 Open the Settings. → Display.
• 🔍 Scroll down to the section "Screen Update Frequency" (or Refresh Rate in English firmware).
• 📊 If there is a point, you will see the current value (for example, 60 Hz, 90 Hz, 120 Hz). On some models, you can switch mode here (auto/fixed).

💡

On smartphones with AMOLED-screens (for example, Xiaomi 12 Pro) the frequency can automatically decrease to 1 Hz in the Always-On Display mode (AOD). It is normal and does not require intervention.

If you don't have a partition, don't despair. That means your smartphone only supports one fixed frequency (usually 60 Hz), or the option is hidden by the manufacturer.

2.Use of the engineering menu (hidden method)

The engineering menu (#4636##) allows you to access the device’s technical data, including the hersh seal, which works on 90% of Xiaomi models, but you need to be careful not to change other settings so as not to disrupt the system.

Step-by-step:

1. Open the phone app and enter the combination: ##4636##
2. In the menu that appears, select Testing (or "Testing" in Russian).
3. Scroll to the Display or Screen section.
4. Find the Refresh Rate option – here will be the current value in hertz.

Close all applications |Plug in charger (on some models menus do not open at low charge)|Do not change other options in the menu |Write down the current value of hertz for comparison-->

Important: Some firmware (MIUI Global for Europe) may have the engineering menu blocked, in which case use alternative methods.

Third-party applications for checking hertz

If the standard methods didn't work, we'll have specialized tools to help, and we've tested 5 apps and selected the most accurate and safe ones.

Refresh Rate Test, which not only shows the current hertz, but also tests its stability.

• 📲 Launch the application and press Start Test.
• 📊 Wait for the check to be completed (10-15 seconds).
• 🔍 The Current Refresh Rate will indicate the current value.

60 Hz (enough for everyday tasks)|90 Hz (balance between smoothness and autonomy)|120 Hz (ideal for gaming and multimedia)|144 Hz and above (maximum performance)|I don't know.-->

4. Check through ADB (for advanced users)

If you want the most accurate data directly from the system, you can use ADB (Android Debug Bridge), which requires connecting a smartphone to a PC, but gives a 100% reliable result.

Instructions:

1. Install ADB Tools on your computer.
2. Turn on USB Debugging on your phone: Settings → About Phone → MIUI version (click 7 times to activate Developer Mode), then Settings → Additional → Developers → Debugging over USB.
3. Connect your smartphone to your PC and type in the command line: adb shell dumpsys display
4. Find the refresh-rate bar – the current value will be indicated here.

This is a good way for developers or users who want to get data without installing third-party applications, but for a normal Hertz test, the methods from the previous sections are sufficient.

5. Visual Testing with Online Services

If you need to quickly evaluate the hertz without installing programs, you can use online tests, which work through the browser and show how the screen displays animations at different frequencies.

Best services:

• 🌐 TestUFO – shows the smoothness of animation at 60 Hz, 120 Hz and 144 Hz.
• 🌐 VSYNC Tester – testing synchronization of personnel.
• 🌐 Blurbusters – checks artifacts at high hertzov.

How to use:

1. Open the service in the Chrome or Firefox browser (on your phone).
2. Choose the test with the frequency you want to test (e.g. 120Hz).
3. Compare the smoothness of the animation on the screen to the reference. If the picture twitches, your screen is running at a lower frequency.

💡

Online tests don't give you an exact hertz value, but they help you visually assess the smoothness of the screen. Use apps or ADB for accurate data.

This method is useful if you want to compare screen performance at different frequencies, for example, after changing the settings in the engineering menu.

Frequent problems and their solutions

When checking the hertz, Xiaomi users often encounter typical errors, and we have collected the most common ones and ways to fix them:

⚠️ Warning: If after changing the hertz through the engineering menu, the screen begins to flicker or artifacts appear, immediately restart the device!

If none of these methods helped determine the hertz, it is possible that your Xiaomi model uses a non-standard implementation (for example, Xiaomi Civi with 120 Hz and adaptive backlight). MIUI.
