How to increase the hertz on Xiaomi: a complete guide to speeding up the screen

Modern smartphone users are increasingly looking at smooth interfaces that are directly affected by screen refresh rates. Xiaomi, Redmi and Poco users often wonder if they can artificially boost that when standard settings don’t allow them to get the most out of the hardware. Increasing the number of hertz (Hz) can dramatically change the way they view animations, scrolling tape and gameplay, making the picture more responsive.

But you have to understand that the physical limit of the matrix is not canceled. If your screen is physically capable of operating at 60 Hz, it is not possible to programmatically accelerate it to 144 Hz without the risk of damaging the display or obtaining image artifacts. However, in many cases, the system defaults to limit the frequency for the sake of energy saving, and hidden engineering menus allow you to remove these software restrictions.

In this article, we will discuss safe methods of activating increased hertz, working with debugging over USB and the nuances of using third-party software. You will learn to distinguish the real capabilities of your gadget from marketing tricks and understand when interference with system files is justified. The main thing is to act carefully so as not to disrupt the stability of the MIUI or HyperOS operating system.

The concept of hertzovka and its impact on the smartphone

The refresh rate of the screen, measured in hertz (Hz), shows how many times a second the image on the display is updated. The standard value for many years was 60 Hz, which means 60 frames per second. Modern flagship and mid-budget models Xiaomi often have matrixes with support for 90, 120 or even 144 Hz, which provides incredible smoothness.

High hertz is critical for gamers and those who spend a lot of time on social networks, and when scrolling text does not blur, and the cursor in shooters moves with minimal delay, but constant operation at maximum frequency quickly puts down the battery and increases the heat output of the processor.

Many users confuse the screen with the clock speed of the processor. If the first parameter is responsible for the smoothness of the picture, the second is responsible for the speed of data processing. Raising one does not guarantee the acceleration of the other, although together they provide a better user experience. It is important to understand the architecture of your device before making changes.

⚠️ Attention: Forced exposure of a frequency exceeding the physical capabilities of the matrix can lead to ripples, color distortion or complete failure of the display.

Android systems in the MIUI shell often use adaptive refresh rates, which means that the smartphone decides when to raise the hertz and when to lower it to 30 or 60 Hz to save charge, and our challenge is to learn how to manually control this process.

Check the current refresh rate and screen capabilities

Before you start modifying your settings, you need to know exactly what hardware you're dealing with. The standard settings menu doesn't always show the real picture, especially if AutoChoice is on. You'd better use specialized utilities to get accurate information.

One of the most reliable ways is to use the Device Info HW or AIDA64 app, which reads data directly from the display controller, showing supported modes and current active frequency, and avoid overclocking attempts where it is physically impossible.

• 📱 Download the Device Info app HW Google Play Store.
• 👁️ Go to the tab "Display" or "Screen".
• 📊 Find the line "Refresh Rate" or "Refresh Rate".
• 🔍 Check the list of supported modes (e.g. 60, 90, 120Hz).

You can also use the built-in developer tools, which we'll talk about in the next sections, but basic diagnostics through third-party software gives a more understandable picture for the average user. If the application only shows 60 Hz, and specs say 90, then the mode is simply not activated in the system.

Activate hidden modes through the developer menu

The safest and most legal way to boost the hertz is to use the developer menu. In MIUI and HyperOS, this section is hidden by default, but activating it does not require superuser rights (Root).

To enter the menu, you need to click on the build version several times in the About Phone section. Once the "You're a developer" notification appears, a new item will open in the advanced settings, which is where the keys to managing the display performance lie.

Inside the developer menu, we're interested in Smallest Width, which indirectly affects rendering, and in some firmware versions, direct refresh rate selection, but most often, ADB commands are required to force activation.

If the standard menu does not have a choice between 60 and 90/120 Hz, then the manufacturer has blocked this option for a particular model or region, in which case we move to more advanced methods of interaction with the system.

Using ADB to Force Hertzov Change

Android Debug Bridge (ADB) is a powerful tool that allows you to send commands to a system directly, bypassing the GUI, and it can change system settings that are hidden from the average user, which requires a connection to a computer.

To get started, you need to install Xiaomi USB Driver drivers and the SDK Platform Tools platform on your PC. Once you connect your phone in debugging mode via USB, you can send commands to change the display configuration.

adb shell wm size


adb shell wm density

However, it is often the SurfaceFlinger command that is used to change the refresh rate (Refresh Rate), and the specific command may vary depending on the version of Android and the chipset (Snapdragon or MediaTek).

Once you have the commands, the changes take effect immediately. If the screen is gone or artifacts are present, just reboot the device, the settings will reset to the previous safe values. Don't be afraid to experiment if you're ready to reboot.

Applications for updating frequency management

If you don't want to mess with the command line, Google Play apps come to the rescue. ROOT-rights or use the same mechanisms ADB, But it's a user-friendly interface. Popular solutions are Refresh Rate Changer and FPS Locker.

The FPS Locker app is particularly effective because it allows you to customize the hertz for each application, for example, you can leave 60 Hz for reading books and YouTube, whine 120 Hz for shooters, where reaction is important.

• 🚀 Refresh Rate Changer: Simple interface, requires developer rights.
• 🔒 FPS Locker: Flexible profile setting for different games.
• ⚙️ SetEdit: System table editor, requires caution.

The advantage of using these programs is that they create shortcuts on the desktop to quickly switch modes, which eliminates the need to connect the phone to the computer every time, but remember that third-party software can have access to system settings.

💡

Use the widget from the FPS Locker app on your desktop to instantly switch between 60Hz (for saving) and 120Hz (for playing) modes without logging in to the menu.

The effect of increased hertzovka on autonomy and heating

Increasing the amount of hertz is not only visual comfort, but also increased load on the components of the smartphone. the display is one of the main consumers of energy, and working at the limit of capabilities significantly reduces battery life.

When you switch from 60Hz to 120Hz, your screen energy consumption can increase by 15-20%, which means you have enough battery power to keep you up for fewer hours of active use, and the GPU has to render twice as many frames.

⚠️ Attention: Constant work on maximum hertzov can lead to accelerated wear of the battery and the appearance of trottling (decreased performance) due to overheating of the body.

The optimal solution is to use adaptive mode if available, or manually switch only when needed.Do not keep 120Hz on around the clock unless you are an avid mobile gamer.

💡

Balancing fluidity and autonomy is key. Turn on a high hertz just for games or tasks where it's really visible to the eye.

Possible problems and ways to solve them

In experiments with refresh rates, users may experience unstable system performance, screen flickering, colors distorting, and some applications crashing, and these are signs that the selected settings are not suitable for the current configuration.

The most common problem is the black screen after settings. In 90% of cases, the usual reboot of the device with the volume and power buttons (hard reset) helps, since the system does not store errors in permanent memory without confirmation, and logging into Recovery Mode and clearing the cache can also help.

If after the changes, the phone began to warm up strongly even in simple, immediately return the settings to factory values. Prolonged overheating can damage the adhesive layer of the display or peel off the plumes.

To sum up, increasing the hertz on Xiaomi is a great way to breathe new life into the interface if you approach it wisely: use diagnostics, test the capabilities of the matrix and do not chase maximum numbers at the expense of stability. Your smartphone will thank you for taking care of its resources.
