Xiaomi Mi 9T: how many hertz in the screen and technical features

Many users, choosing a smartphone mid-range, ask about the quality of the display of the picture. In particular, owners of the model Xiaomi Mi 9T are interested in how many hertz in the screen of their device, this characteristic directly affects the smoothness of the animations of the interface, scrolling pages and, of course, gameplay.

The answer to this question is not as clear as it may seem at first glance. Standard specifications indicate a base frequency, but modern technology allows the system to dynamically control this parameter. Understanding how the matrix works in your case will help to better customize the gadget for personal needs.

In this article, we will discuss in detail the technical specifications of the display, methods of checking the current frame rate and the nuances that are silent in advertising brochures. You will learn why 60 Hz is not always a constant, and how to get the most out of your device.

Technical characteristics of the Super AMOLED matrix

The screen of the Xiaomi Mi 9T smartphone is made using Super AMOLED technology, which is already the standard for flagship and sub-flagship solutions. The diagonal is 6.39 inches, and the resolution of FullHD + (2,340 by 1,080 pixels) provides high pixel density.

The baseline refresh rate is 60 Hz, which means that the display changes 60 times per second. For most everyday tasks, such as reading the news, watching videos or chatting in messengers, this value is more than enough. The human eye perceives the picture as completely smooth and natural.

However, it is worth considering that the hardware of the smartphone is able to process graphics at different speeds. In games or when playing specific video content, the number of frames per second can vary. It is important to distinguish between the refresh rate of the matrix and the number of frames that the Snapdragon 730 processor is capable of producing.

Color reproduction and brightness also play a role in subjective perception of hertzovka. Thanks to the support of the HDR10 standard and the wide color gamut of the DCI-P3, the picture seems more saturated, which visually hides the lack of high hertzovka characteristic of newer models.

💡

The Xiaomi Mi 9T screen runs at a base frequency of 60 Hz, which is the standard for AMOLED-matrixes of that period of release, providing a balance between quality and autonomy.

How to Check the Real Update Frequency

The official specifications are one thing, but the user often wants to see the confirmation with their own eyes. There are several ways to know how much hertz the screen is giving out at a given time. The simplest method does not require installing third-party software, but it is less accurate.

For more information, you can use specialized apps from the Google Play store, like TestUFO or Device Info HW, which allows you to track your current refresh rate in real time, and this is especially useful for gamers who are watching each frame.

• 📱 Download the system monitoring application from a reliable source.
• 👁️ Run a determination test. FPS (frame-of-second).
• 📊 Compare the data with the declared characteristics.

Another method is to use built-in developer tools, although they don't always show the hertz directly, but rather the load on the rendering. If you see a stable 60 FPS in the interface, then the system is working normally, and a drop below 50 may indicate optimization problems.

⚠️ Warning: Don't blindly trust apps that promise to "overclock" the screen to 90 or 120 Hz by software. 9T They do not allow them to operate at frequencies higher than the manufacturer's stated frequency.

Checking through a computer with USB debugging gives the most accurate log files, but this method is difficult for the average user. It is enough to visually assess the smoothness of the scrolling and the data of diagnostic utilities to draw conclusions about the state of the display.

The impact of frame rate on gameplay

For mobile gamers, the question of how many hertz is on the screen is a top priority. The Xiaomi Mi 9T has a Snapdragon 730 processor, which pairs with the Adreno 618 graphics accelerator shows decent results. However, the physical limit of the matrix at 60 Hz sets the upper bar for visible smoothness.

Even if a game is capable of producing 90 or 120 frames per second, you won’t see a difference on a 60Hz display. Excessive frames will simply be discarded or cause a tearing effect if vertical synchronization is not enabled. So optimizing games at 60 FPS is more important here than chasing high values.

However, the stability of frame rates is more important than its peak values. If in a heavy game the FPS jumps from 30 to 60, it feels like micro-twitching. Xiaomi Mi 9T tries to keep a straight line of 60 frames, which provides predictable control.

Let’s look at the indicators in popular disciplines:

Importantly, long gaming sessions can lead to trolling (decreased performance due to heat), which indirectly affects frame rate.

💡

For games, enable Game Turbo in your security settings, which optimizes resource allocation and can prevent FPS from falling into the game.

Display settings in MIUI

The MIUI operating shell on the Xiaomi Mi 9T provides flexible tools for image calibration. Although you can’t manually switch the Hertz frequency here (since it’s fixed hardware), you can change other parameters that affect perception.

In the Settings menu → Screen, the following options are available:

• 🎨 Color scheme: the choice between saturated and standard colors.
• ☀️ Brightness level: manual adjustment or auto-brightness.
• 🌙 Reading mode: Reduction of the blue spectrum for eye comfort.
• ⏱️ Time to Shutdown: Setting the screen timeout.

It is also worth paying attention to the function. DC Dimming. It's often hidden in the Developer menu or activated through a special code in the Phone app. It reduces the flickering of the screen at low brightness, which is critical for the development of the phone. AMOLED-matrices using PWM (pulse-wide modulation).

To activate hidden functions, you often need to enter a special code in the dialer. For example, ##6484## opens the engineering menu where you can run display tests. Be careful when changing the settings in the engineering menu so that you do not disrupt the system.

⚠️ Attention: Initiation of the regime DC Dimming can slightly change color reproduction or cause a mura effect at low brightness levels.

Comparison with modern analogues

When we talk about how many hertz there is on the Xiaomi Mi 9T screen, you can't ignore the context of time. 60 Hz was the norm when it came out. Today, the market is being taken over by panels at 90, 120 and even 144 Hz. What's the difference for the user?

The transition from 60 Hz to 120 Hz is immediately noticeable: animations become more fluid, social media tape scrolling smoother, and cursor movements in games are more responsive. However, the human eye stops noticing the difference after 90-120 Hz, so further increase in hertz has diminishing returns.

The main disadvantage of high frequencies is power consumption. 120 Hz screen consumes much more energy than 60 Hz. Xiaomi Mi 9T with its battery of 4000 mAh and 60 Hz screen shows excellent autonomy, often surpassing new models with “gluttonous” 120 Hz panels.

Comparative table of screen characteristics:

As you can see from the table, the Mi 9T remains competitive in color rendering quality, despite not having a high hertz. For those who don't play competitive shooters on their phone, the difference in everyday use will be minimal.

Typical problems and their solution

Over time, the owners of Xiaomi Mi 9T They may have problems with the display, and one of the common complaints is that they're burning-in. AMOLED-This is a residual image of static interface elements that you can see on a white background.

Another problem is the loss of touchscreen sensitivity or the appearance of phantom presses, which can be due to a software failure, as well as physical damage to the plume or the module itself, in which case calibration through the engineering menu can temporarily help.

If the screen starts to flicker or change shades, check the auto-brightness settings. Sometimes the light sensor gets dirty or doesn't work properly. Wipe the top of the screen and make sure the protective glass doesn't create glare that interferes with the sensor.

For serious artifacts (bands, stains), software methods are powerless. Replacement of the display module is required. When buying parts, pay attention to the quality of the copy: original Super AMOLED matrices are expensive, and cheap counterparts (TFT/IPS) have the worst viewing angles and colors.

⚠️ Warning: If colored bars appear on the screen or it stops responding to touches after falling, do not try to "warm up" or press the display. this can damage the battery or aggravate the detachment of the plume.
