Where to see the screen refresh rate on Xiaomi: all methods from settings to service codes

Refresh rate is a key parameter that affects image smoothness, interface responsiveness, and even device autonomy. On Xiaomi smartphones and TVs, this can range from the standard 60Hz to 240Hz on flagship models, but it’s not always clear where to check it, especially if it’s a dynamic frequency that automatically adjusts to the content.

In this article, we will discuss all possible ways - from built-in settings MIUI to hidden engineering menus and third-party apps, you will learn how to determine the current frequency on Redmi, POCO, Black Shark or Mi TVs TV, And what to do if the device doesn't show real values, and it's important that on some models, the manufacturer artificially limits the maximum frequency depending on the region or version of the firmware, and we'll tell you how to get around that.

1. Verification through standard MIUI settings

The easiest way is to use the built-in system options on most Xiaomi smartphones (starting with the use of the new system). MIUI 12) the screen refresh rate is placed in a separate menu, but its location depends on the model and version of the shell.

For devices with AMOLED-screens (for example, Xiaomi 13 Ultra, Redmi) K60 Pro, the way will be:

1. Open the Settings → Display.
2. Slip on the screen refresh rate (or Adaptive frequency).
3. Here you will see the available values (e.g. 60Hz, 90Hz, 120Hz) and the current active.

On budget models (for example, Redmi Note 12 or POCO M5) The menu may be called differently:

• 🔍 Settings → Screen. → Permission and frequency of update
• 📱 Settings → Additionally. → Display frequency (on some versions) MIUI for POCO)
• 🎮 Settings → Turbo-play mode → Screen frequency (on Black Shark)

💡

If only one value is displayed in the settings (e.g. 60Hz), but you are sure that the screen supports 120Hz, try updating the firmware or turning on the developer mode (more on this below).

On Mi TVs. TV or Redmi Smart TV path:

1. Press the Settings button on the remote → select All settings.
2. Go to General. → About the system → Technical information.
3. Scroll down to the Display block - here will be the Refresh Rate string.

💡

On Xiaomi TVs, the refresh rate can be displayed in hertz (Hz) or in format "50i/60i" line-to-line.

2.Use of the Developer Mode

If you don't have frequency information in your standard settings, you can find it in the developer menu, which works on all Android devices, including Xiaomi.

First, activate the developer mode:

1. Open the Settings. → The phone.
2. Find the MIUI version string and tap it 7 times in a row.
3. You will be notified that you have become a developer.

Now go to:

1. Settings → Additionally. → For developers (or the System) → Advanced settings → For developers).
2. Scroll down to the Monitoring or Journals block.
3. Find the Show Screen Update Rate (or Refresh Rate) and turn it on.

Then, in the upper right corner of the screen, a small counter will appear that displays the current frequency in real time, and note that some firmware may call this parameter differently:

• 📊 Debugging → Show screen updates
• 🔄 Visualization → Frequency of update
• 🖥️ Hardware acceleration → Monitor FPS

On Xiaomi TVs, the developer mode is activated differently:

Settings → Device → About It → Click 5 times on “Android Version”

Then on the Settings menu → Additional item for developers will appear, where you can turn on the display of frequency.

3. Third-party applications for frequency verification

If the built-in methods don't work or display incorrect data, use specialized utilities that not only show the current frequency, but also test the stability of the screen.

Top.-3 apps:

1. Refresh Rate Test (from Optimal App) – shows the current and maximum frequency, and also checks whether the screen supports adaptive mode. 📥 Download: Google Play ⚡ Feature: Test for "break" frame (screen tearing).
2. Display Tester – analyzes all display parameters, including color coverage and response time. 📥 Download: Google Play ⚡ Feature: Shows the real frequency, even if the system hides it.
3. CPU-Z — The Device tab displays the screen frequency in the Display section. 📥 Download: Google Play ⚡ Feature: Works without the Internet and does not require root rights.

For Mi TVs, TV fitting TV Refresh Rate Tester (available from the Mi App Store) runs test videos at different frame rates (24) FPS, 30 FPS, 60 FPS) And it shows you how the screen handles them.

Important: on devices with LTPO-screens (for example, Xiaomi 14 Pro) frequency can dynamically vary from 1 Hz to 120 Hz. Applications will show the current value, but for accurate diagnosis it is better to use the ADB (about this in the next section).

4. Check through ADB (for advanced users)

If you need to get accurate data on supported frequencies or unlock hidden modes, use Android Debug Bridge (ADB). This method requires connecting the smartphone to the PC, but gives the most complete information.

Instructions:

1. Install ADB Tools on your computer.
2. Enable USB debugging on your smartphone (Settings → Developers).
3. Connect the device to the PC and enter in the command line:

adb shell dumpsys display

In the conclusion, find the DisplayDeviceInfo block. Here will be the lines:

• Current refresh rate is the current frequency.
• Supported refresh rates – all supported values.
• App requested refresh rate is the frequency requested by the application.

Example of output for Xiaomi 13T:

DisplayDeviceInfo{




...




current refresh rate=120.000000 Hz




supported refresh rates=[60.000000, 90.000000, 120.000000]




...




}

For Xiaomi TVs, the team is different:

adb shell dumpsys SurfaceFlinger --display-id 0

Install Xiaomi drivers on PC|Enable debugging on USB phone-on|Connect the original USB-cable|Start the command line on behalf of the administrator|Check the connection of the adb device team

-->

If there are values in the list of supported frequencies that are not in the settings (for example, 144 Hz), they can be unlocked using the command:

adb shell settings put global peak_refresh_rate 144

⚠️ Warning: Forced frequency changes can cause the screen to overheat or deteriorate its autonomy. Before experimenting, check if your model officially supports these values.

Technical specifications and official sources

If you need to know the maximum refresh rate (rather than the current one), the easiest way to check the official data is to buy a device or if you suspect that the firmware limits the display.

Where to look:

• 🌍 Xiaomi official website: Go to the model page (e.g. Redmi Note 13 Pro)+). The Display section will specify the frequency (for example, 120Hz AMOLED).
• 📄 Box documentation – on some models (e.g. Black Shark 5 Pro) the frequency is indicated on a sticker or in a booklet.
• 🛒 Sellers’ pages (Wildberries, M. Video, AliExpress) – but be careful: sometimes sellers provide incorrect data.

For Mi TVs, TV frequency depends on the model and region:

Xiaomi TVs for China may have higher frequency than the global versions. TV Q2 65 in China supports 144 Hz, and in Europe only 120 Hz.

If you don’t find your model in the table, check it by code (for example, by code, L55M9-9A for Mi TV 4S 55") Xiaomi's support website.

6. Service codes and engineering menu

Xiaomi smartphones have hidden menus where you can see detailed information about the display, including the actual refresh rate, which does not work on all models, but it is worth a try.

Major teams:

• ##4636## → Device information → Display (shows the current frequency and resolution).
• ##225## → Calibration → Display Test (Flash and Frequency Test).
• ##36446337## - Engineering menu for screen testing (works on Redmi and the Redmi screen). POCO).

For Mi TVs, TV The service menu opens like this:

1. Turn off the TV remote.
2. Press the Menu button on the remote. + Volume Down and, holding them, turn on the TV power button.
3. Release the buttons in 5 seconds and the service menu will open.
4. Go to Display. → Panel Info, where the Refresh Rate string will be.

⚠️ Warning: Changing the parameters in the engineering menu without knowing the consequences can lead to a:

• 🔥 screen-heating;
• 🖥️ artifacts of the image (strips, flickering);
• 🔋 Increased battery consumption (on smartphones).

If after the changes the screen started to work incorrectly, reset the settings through Settings. → System system → Resetting settings.

7. Frequent problems and their solutions

Sometimes users are faced with situations where the refresh rate of the screen does not correspond to the expected or the device does not "see" the available modes.

Problem 1: Only 60Hz is displayed in the settings, although the screen supports 120Hz.

• Update your firmware to the latest version (Settings → System Update).
• Check the region of the device: on some models (for example, POCO F5) for India, maximum frequency is limited to 90 Hz. Change region via Settings → Additionally. → Region.
• Install an alternative firmware (e.g. Xiaomi.EU) where restrictions are removed.

Problem 2: The frequency spontaneously changes (e.g., jumps between 60 Hz and 120 Hz).

Decision:

• Turn off the adaptive frequency in the screen settings.
• Check if the battery saving mode is enabled (Settings) → Battery → Energy saving regime).
• Remove apps that can control frequency (such as Game Turbo or Dark Mode).

Problem 3: On the TV Mi TV In games, the frequency does not rise above 60 Hz.

Decision:

• Enable Game Mode in the settings HDMI-port.
• Connect the console or PC through HDMI 2.1 (on old ports) HDMI 2.0 maximum frequency - 60 Hz).
• Update your TV firmware (in some versions, PatchWall limits frequency to save resources).

Problem 4: After the update MIUI The screen frequency has dropped to 60 Hz and does not change.

Decision:

• Reset the screen settings: Settings → Display. → Reset to factory.
• Clear the system cache: Settings → Memory → Clear the cache.
• If the problem persists, roll back to the previous firmware version via Fastboot.

💡

If after changing the firmware screen began to flicker or appeared stripes, return the standard frequency (60 Hz) and wait for the official patch from Xiaomi.
