How to change the hertzovka on Xiaomi: all ways for smartphones and TV

Screen refresh rate (hertz) is one of the key parameters that affect the smoothness of the image and responsiveness of the device. On Xiaomi smartphones and TVs, this parameter can be changed through standard settings, hidden functions or even manual intervention. However, not all models support dynamic Hz change, and some require unlocking additional options.

In this article, we will discuss all the current ways to change the hertz on Xiaomi devices, including MIUI smartphones and Mi TVs. You will learn how to turn on 90/120/144 Hz, what restrictions the manufacturer imposes, and what to do if the desired option is hidden.

What is a squirrel and why change it?

Hertz (screen refresh rate) is measured in hertz (Hz) and shows how many times a second the screen updates the image. The higher the value, the smoother the animation, but the more the load on the processor and battery.

• 📱 60Hz is the standard for most smartphones (savings charge, but animations are less smooth).
• 🔥 90/120/144 Hz - premium mode for gamers and fans of a smooth interface (the battery goes down faster).
• 📺 50/60 Hz – for TVs (affects video playback without jerks).

On Xiaomi devices, the frequency can automatically adjust to content (for example, 60 Hz for video and 120 Hz for games), but sometimes manual adjustment is required. For example, if you notice slowdowns in games or, conversely, too fast battery discharge – it may be worth experimenting with hertz.

⚠️ Note: On Xiaomi budget models (e.g. Redmi) 9A or POCO M3) screens support only 60 Hz. Attempt to force the frequency through ADB or modified software can cause image artifacts or even the display to fail.

How to check the current hertzovka on Xiaomi

Before you change your settings, make sure your device is really high frequency, and you can do this in a number of ways:

1. Through screen settings: 🔧 Open the Settings. → Display. → Screen refresh rate. 📊 If you don’t have an option, your model doesn’t support manual Hz change.

With the help of applications:

• 📱 Install DevCheck or CPU-Z Google Play.
• 🔍 In the Display section, see the Refresh Rate option.
• Through Hidden Menu (for Advanced): Adb shell dumpsys display Look for the currentRefreshRate line.

Some models (such as the Xiaomi 12 Pro or POCO F4 GT) offer FHD+ Adaptive Frequency, which automatically lowers the screen resolution at high hertz to reduce the CPU load.

⚠️ Attention: On Mi TVs TV Changing the hertz can lead to incorrect video playback. For example, films in 24 frames will twitch at 60 Hz. For movies, it is recommended to turn on Auto mode or manually set 50 Hz (for example, for movies, it is recommended to turn on the Auto mode or manually set up 50 Hz). PAL-content).

How to Enable Hidden Hertz Modes Through ADB

If the settings do not have the right option (for example, 144 Hz on POCO F5), it can be unlocked via ADB (Android Debug Bridge), which requires a computer connection and basic command line knowledge.

Instructions:

1. Enable Developer Mode: 🔧 Go to Settings. → The phone. → Version. MIUI. 🔘 Tap it 7 times until the notification “You became a developer” appears".

Activate the debugging via USB:

• 🔧 Back to Settings → Additionally. → For developers.
• 🔘 Turn on the debugging switch. USB.
• Connect your phone to your PC and execute the commands: adb shell settings put global peak_refresh_rate 144.0 adb shell settings put global min_refresh_rate 60.0 Where 144.0 — Maximum frequency (set your desired value).

After the reboot, a new item will appear in the screen settings. On some models (for example, Xiaomi). 13 Ultra: This method only works after disconnecting MIUI Optimization in the developer (adb shell settings put global) miui_optimization_disabled 1).

* - Requires disabling MIUI optimization.

💡

If so, ADB-The Hertzov commands have not changed, try resetting the screen settings to factory (Settings) → Display. → Resetting. Sometimes it helps to apply new parameters.

Features of changing hertzovka on Mi TVs

On Xiaomi TVs, the frequency-shifting algorithm is different from smartphones. Here, the hertzovka is tied to the signal source (HDMI, embedded, TV-tune:

• 📺 When you connect to a PlayStation 5 or Xbox Series X, the TV automatically switches to 60Hz (or 120Hz if supported).
• 🎬 For cinema (24 fps) it is better to manually set 50 Hz (for the film). PAL) or 60 Hz (for) NTSC), avoiding jerks.
• 🖥️ When used as a PC monitor, you can fix 60 Hz through settings HDMI.

How to change the hertzovka on Mi TV:

1. On the remote, press Menu → Settings → Image → Additional.
2. Select Update Frequency (or Mode of Movies).
3. For HDMI-source: 🔌 Connect the device and go to Settings → HDMI → Signal format. 🔄 Choose the car or manually specify 50/60 Hz.

⚠️ Attention: On Mi TVs TV s HDMI 2.0 maximum frequency at resolution 4K limited to 60 Hz. 120 Hz will require a lower resolution to 1440p use HDMI 2.1 (available only on flagship models, such as the Mi) TV Master).

Problems after changing the hertzovka and their solution

Incorrect frequency settings can cause a number of problems, from minor glitches to serious failures. Let's consider typical situations and ways to fix them:

If after experimenting with ADB, the phone stopped booting or the screen displays artifacts, try:

1. Reset settings via Recovery (press Power + Volume Up when enabled).
2. Reflash the device through the Mi Flash Tool (instructions on the official website).
3. Contact the service center (if the warranty is valid).

On budget models (for example, Redmi 10A or POCO M5) screens are limited to 60 Hz. Trying to circumvent this limitation is pointless – the hardware is not designed for high frequency.
