Xiaomi Redmi 9: How many hertz screen and refresh rate

When choosing a budget smartphone, potential buyers often pay attention not only to the processor and memory, but also to image quality. One of the key parameters that affect interface smoothness and visual comfort is the frequency of updating the matrix. The question of how many hertz screen the popular Redmi 9 model worries many users who want to get the most for the money available.

In this article, we will discuss in detail the technical characteristics of the display device, explain the difference between the declared and the real indicators, and also tell you how to independently check the refresh rate. Understanding these nuances will help you to properly customize the gadget for your needs or make an informed decision when buying.

Technical characteristics of the Redmi 9 display

Xiaomi Redmi 9 is equipped with an IPS LCD matrix with a diagonal of 6.53 inches. screen resolution is 2340×1080 pixels, which provides a density of about 395 dots per inch (PPI). However, the main parameter of interest to gamers and active users remains the refresh rate. In the specifications of the manufacturer officially stated value of 60 Hz.

This means that the screen is updated 60 times per second. For the budget market, this is a standard indicator that ensures acceptable smoothness of the interface and video viewing. Despite the absence of 90 or 120 hertz, high-quality color calibration and the presence of protective glass Corning Gorilla Glass 3 make the display competitive.

It is worth noting that some users confuse refresh rate with touch sampling rate. If the first is responsible for smoothness, the second determines the speed of the screen to touch. The Redmi 9 uses standard capacitive touch technology with multi-touch, but the exact data on the frequency of the survey is often closed.

💡

60Hz is the standard for most video content (movies, TV), so on this smartphone you will not notice the out-of-synchronization of frames when watching videos.

It is important to understand that the matrix IPS, The one that's installed in this model has its advantages, such as good viewing angles and natural color reproduction. AMOLED-The Redmi 9 screen is strictly 60 Hz and does not support software or hardware enhancement of this value.

Does Redmi 9 support 90 Hz or 120 Hz?

Questions are often asked in forums and tech communities about overclocking or hidden settings, and users ask if 90 hertz can be activated on Redmi 9 via an engineering menu or third-party apps, and unfortunately the answer is no.

The hardware of the smartphone, including the display controller and the matrix itself, is physically limited to a maximum of 60 frames per second. Even if you can find a modified firmware with modified configs, this will not cause the pixels to switch faster. Attempts to force the screen can lead to instability of the system.

By comparison, the newer Redmi Note series already has high-frequency screens, but Xiaomi’s baseline 9th-generation Redmi lineup has been putting its bet on energy efficiency and affordability, leaving the standard 60Hz.

• 📉 The standard refresh rate is 60 Hz.
• 🚫 Hardware support for 90 Hz or 120 Hz is missing.
• ⚙️ Screen overclocking software hacks do not work and are dangerous.
• 🔋 60 Hertz Limit Positively Affects Autonomous Life.

💡

Trying to increase the refresh rate on Redmi 9 software methods is useless, as this is a limitation of hardware, not software.

How to Check the Real Screen Frequency

If you're questioning the manufacturer's integrity or want to make sure the display is running, there are proven diagnostic methods, and the easiest method is to use the built-in features, if they're available in your version of the MIUI shell.

For more information, you can use third-party utilities from Google Play. Apps like Device Info HW or AIDA64 read data directly from the system and show the exact characteristics of the connected display. In the "Display" or "Screen" section, you will see the "Refresh Rate" string.

The following verification procedure is performed through AIDA64:


1. Download and install the AIDA64 application.




2. Launch the program and wait for the data collection.




3. Go to the Display section.




4. Find the "Refresh Rate" option - 60 Hz should be indicated there.

There's also a visual test with another smartphone's camera: point the second phone's camera at the Redmi 9 screen and take a slow-motion video. If you see clear stripes or flickering, it might indicate PWM (pulse-latitude modulation) or specific backlighting, but the frame refresh rate will remain at 60Hz.

The impact of the refresh rate on the smartphone

A 60Hz frequency means that the smartphone updates the picture every 16.6 milliseconds. For everyday tasks such as calls, messengers and news feeds, this is enough. The human eye can hardly notice the difference between 60 and 90 hertz with static content.

However, in dynamic scenes, such as scrolling heavy web pages or in games, the difference becomes noticeable. On screens with high frequency of movement, they look smoother, and the "feet" behind the finger when scrolling is less pronounced. On Redmi 9, you can notice a slight delay or less smooth movement of the interface animations compared to the flagships.

⚠️ Attention: In high-level games FPS (The screen will still be limited to 60 frames, even if the processor is able to output 90 frames per second. FPS, You won’t see the benefits of high frequency on the Redmi 9 display.

However, MIUI shell optimizations can mitigate these disadvantages. transition animations are set up to create the illusion of smoothness. For most users who are not professional esportsmen, the comfort of using Redmi 9 remains high.

• 🎮 In games. FPS It will be limited to 60 frames per second.
• 📱 Animation. MIUI optimized for 60 Hz.
• 👁️ For reading and social networks, the difference from 90 Hz is minimal.
• 🔋 Lower refresh rate saves battery power.

Display settings in MIUI for Redmi 9

While you can’t change the physical refresh rate, Xiaomi provides a range of tools to improve visual perception, and you can find settings in the settings menu that affect color reproduction, font size and screen modes.

To get into the settings, go along the path: Settings → Screen → Colors and saturation. There are various color schemes available here. Also in this section is the Read Mode setting, which reduces eye strain by making the image warmer.

Another useful feature is adjusting the frequency of the touch layer in game mode, although in Redmi 9 it can be limited. In the Settings → Special features → Improve visibility, you can find additional options such as eliminating flicker.

Don't forget to calibrate. Factory settings can feel too cold or too warm. Experimenting with a color temperature slider can produce a more natural image, which will subjectively improve picture quality even at 60 Hz.

Comparison with competitors in the budget segment

Redmi 9 was one of the leaders in terms of price and quality at the time of its release, but competitors were not dozing off, and many devices in the same price range also offered 60Hz IPS arrays, but some models had already begun to move to 90Hz.

For clarity, compare the characteristics of the Redmi 9 with typical representatives of its class and newer models:

As you can see from the table, Redmi 9 beats many of its direct screen resolution competitors by offering Full HD+ instead of HD+. This makes the image sharper, offsetting the standard refresh rate. Buying this phone gives you a quality picture, even if it's not the fastest on the market.

💡

When buying a used Redmi 9, be sure to check the screen for broken pixels and uneven backlighting, as this is a common problem of budget IPS matrices.
