Setting the screen refresh rate on Xiaomi: from 60 to 144 Hz

Screen refresh rates are one of the key parameters that affect the smoothness of the display of content on a smartphone. POCO This can range from the standard 60Hz to 144Hz in flagship models, but how do you adjust the herz to balance between smooth interfaces and autonomy? Many users do not even suspect that their smartphone supports high frequency, or are afraid to turn it on because of myths about fast battery discharge.

In this article, we will discuss all ways to change the refresh rate on different versions. MIUI (12 to 14), including hidden settings for older models, you’ll learn how to check the current hertz, what modes are available on your device, and how to optimize screen performance for games, videos, and everyday tasks. And also – debunk popular misconceptions and give advice on eliminating typical problems.

If you've never changed that, chances are your smartphone is factory-based — usually 60Hz or Adaptive Frequency. Meanwhile, choosing the right hertz can dramatically change the experience of using it, from the smoothness of social media scrolling to the response of shooters. But it's not that simple — high frequency requires more resources, and on some models can even lead to overheating with prolonged use. Let's figure out how to find the middle ground.

1. Which Xiaomi smartphones support a high refresh rate?

Not all Xiaomi devices are equipped with screens with a frequency above 60 Hz. The technology has been widely introduced only since 2020, and even in the budget series of Redmi Note and the new model. POCO. Here are the key models with support for increased hertzovka:

• 📱 Flagship series: Xiaomi 12/13/14 Pro, Mi 11 Ultra, Black Shark 4/5 — before 120–144 Hz.
• 💰 Mid-segment: Redmi K50/60 Pro, POCO F4/F5, Xiaomi 11T/12T — usually 90–120 Hz.
• 🔥 Budget models: Redmi Note 11 Pro+, POCO X4/X5 Pro — 90–120 Hz (sometimes with restrictions).
• ⚠️ Exceptions: Redmi 9/10, POCO M3/M4 — only 60 Hz (even if the characteristics indicate otherwise).

To find out exactly what the maximum frequency supports your smartphone, check the official specifications on the Xiaomi website or use applications like AIDA64 (Note: Some models (e.g. Redmi Note 10 Pro) have 120Hz, but only in Adaptive Frequency mode, not fixed frequency mode.

It's important, on devices with AMOLED-screens (e.g. Xiaomi 13 or Xiao) POCO F5) High frequency can lead to flickering at low brightness due to the features of the technology PWM. If you are sensitive to this, it is better to limit yourself to 60 Hz in the dark.

2. How to check the current screen refresh rate

Before you change your settings, it’s helpful to know which hertz is working with your smartphone right now.

Method 1: Through the MIUI settings

1. Open the Settings → Screen.
2. Find the screen refresh rate (in some versions – Smoothness of the screen).
3. The current value will be highlighted (e.g. 90 Hz or Adaptive).

Method 2: Using applications

• 📊 CPU-Z — Display shows the current and maximum frequency.
• 🔍 DevCheck – displays hertz in real time (useful for adaptive mode).
• 🎮 Game Bench – Analyzes the frequency of games.

Method 3: Online Tests

Go to the TestUFO website in your smartphone browser. In the Frame Rate section, select 60Hz, 90Hz If the image is smooth, your screen supports this frequency.

💡

If you see "teared" lanes instead of smooth motion when you test on TestUFO, then your smartphone is running at 60 Hz, even if the settings say otherwise. MIUI or limitation of a particular application.

3. Step-by-step instruction: how to change the refresh rate

The process of setting up depends on the version MIUI Here is a general guide for most devices (relevant to the MIUI 12–14):

Step 1. Open the screen settings

Go to Settings. → Screen. On some devices (e.g, POCO F3) The path may be different: Settings → Display. → Additionally.

Step 2. Find the section "Refrequency of Update"

The option can be called in different ways:

• Screen refresh rate (most models)
• Smoothness of the screen (Redmi Note 11)
• Adaptive frequency (Xiaomi 13)

Step 3. Select mode

Options available:

• 🔄 Adaptive – automatically adjusts to content (recommended for balance).
• ⚡ Maximum – fixed frequency (for example, 120 Hz).
• 🔋 60 Hz - charge savings.

Step 4: Save the changes

Click Ready or go back, settings will apply automatically. No reboot is required.

Make sure the screen doesn’t flicker when scrolling|

Check the smoothness in games (if the game supports high hertzovka)|

Run the TestUFO test for visual evaluation|

Watch your battery consumption for an hour.-->

Note for older models: On some devices (e.g. Redmi) K30 Pro) the option is hidden. To activate it, you need to:

1. Enable Developer Mode (7 times press the Version) MIUI In Settings → The phone).
2. Go to Settings → Additional → For developers.
3. Find the screen refresh rate and select the value.

Adaptive frequency vs fixed: which one to choose?

Many users don't understand the difference between adaptive mode and fixed frequency, so let's look at the pros and cons of each.

When to choose an adaptive mode?

• 📱 If you use your smartphone for everyday tasks (social networks, instant messengers).
• 🔋 If autonomy is more important than smoothness.
• 🌍 If the frequency of the network (4G/5G) Unstable – Adaptive mode reduces load.

When to choose a fixed frequency?

• 🎮 For gamers (in type shooters) PUBG Mobile or Call of Duty High Hertz gives an advantage).
• 🎥 To watch high-quality videos FPS (if the content is supported).
• 🛠️ If the adaptive mode is not working properly (for example, often subfreezing").

⚠️ Note: On some models (e.g. Xiaomi 12 Pro), adaptive mode can ignore game settings, forcefully lowering the hertz.

5. Hidden settings: how to unlock additional modes

On some Xiaomi smartphones, the manufacturer limits the choice of frequencies. POCO X3 The Pro is only available by default at 60Hz and 120Hz, although the screen supports 90Hz. To unlock hidden options, you can use the ADB-commands or third-party utilities.

Method 1: Through ADB (for power users)

1. Install Platform Tools on your PC.
2. Connect your smartphone to USB And turn on the debugging. USB (Settings → The phone. → Version. MIUI → 7 times press).
3. Open the command line in the adb folder and type: adb shell settings put global peak_refresh_rate 90 adb shell settings put global min_refresh_rate 60 (substitute 90 fittingly).
4. Reset the device.

Method 2: SetEdit (without root)

⚠️ Attention: Incorrect values in SetEdit can cause the interface to crash (for example, the screen will flicker or refuse to turn on!

Method 3: Castom firmware

If your device supports unlocking the bootloader, you can install firmware like xiaomi.eu or Pixel Experience, where the frequency is configured flexibly, but this voids the warranty and requires technical skills.

💡

Changing hidden settings can lead to unstable screen operation. If artifacts (strips, flickering) appear after experiments, reset to factory settings or return standard values through ADB.

6.Frequency optimization for games and videos

High refresh rates are especially important in dynamic games and when watching high-speed video. FPS. But not all apps work properly with non-standard hertzov. Here's how to set it up correctly:

For games:

For the video:

• 🎥 On YouTube or Netflix, high frequency only works if the video itself is high. FPS (for example, 60+ personnel).
• 🔍 Check the player settings: in MX Player or VLC It can be a Sync to display option.
• 📺 For local files, convert the video to 60+ FPS with HandBrake.

Challenges and solutions:

• ❌ The game does not use 120Hz: Check if it supports high frequency (list is available on XDA-Developers).
• ❌ Video twitches: Turn off adaptive frequency or set fixed 60Hz.
• ❌ Screen flickering in games: It could be a conflict with DC Dimming (turn it off in screen settings).

💡

Like in games. PUBG Mobile or Free Fire, the high refresh rate of the screen gives a real advantage - the image is updated more often, and you react faster to the actions of opponents. FPS The game is consistently high (e.g. 90).+).

7. Frequent problems and their solutions

When you change the refresh rate, users encounter common bugs, and here are the most common ways to fix them:

Problem 1: The screen flickering or illuminated

• 🔦 Reason: Conflict with technology DC Dimming (adjusting brightness without flickering).
• 🛠️ Solution: Turn it off DC Dimming in Settings → Screen. → Additionally.

Problem 2: Fast battery discharge

• 🔋 Reason: 120Hz constant work increases the load on the processor and screen.
• ⚡ Solution: Switch to Adaptive Mode or lower the frequency to 90Hz.

Problem 3: Frequency resets after rebooting

• 🔄 Cause: Failure to work MIUI or conflict with energy saving settings.
• 📱 Solution: Reset screen settings to factory or update firmware.

Problem 4: Incorrect display in some applications

• 🚫 Reason: The app is not optimized for high frequencies (like TikTok or Instagram).
• 🔧 Solution: Add the app to the Battery Optimization exceptions or switch to 60Hz.

Problem 5: Heating the device

• 🔥 Reason: Long-term work for 120+ Hz increases chipset temperature.
• ❄️ Solution: Use adaptive mode or cooling case.

⚠️ Attention: If the screen flashes spontaneously after the frequency change, or color artifacts appear, this may indicate a hardware malfunction (for example, a plume detachment.

8. Myths about refresh rate on Xiaomi

There are many misconceptions around the hertzovka.

Myth 1: “High frequency is always better”

❌ Reality: In practice, the difference between 90 Hz and 120 Hz is only noticeable in dynamic scenes (games, scrolling.

Myth 2: “Adaptive frequency saves charge”

❌ Reality: Savings are small (5-10%), but the main battery consumption depends on the processor and network, not the screen.

Myth 3: AMOLED-High frequency screens are harmful"

❌ Reality: Hertzov does not spoil the matrix by itself. AMOLED at high frequencies may be manifested PWM-flickering, which is bad for the eyes.

Myth 4: “All games support 120Hz”

❌ Reality: Most mobile games are limited to 60 FPS, And the high screen frequency doesn't give you the advantage, PUBG Mobile (in graphics settings).

Myth 5: “Frequency can be increased above factory frequency”

❌ Reality: Maximum Hertzovka rigidly laid in the firmware and "overclocking" is impossible without modification of the core (which leads to loss of warranty).

💡

The best choice is adaptive mode with manual switching of 120 Hz for games, which gives a balance between smoothness and autonomy without unnecessary compromises.
