Xiaomi Redmi Note 9 Pro: How much hertz screen and how it affects the experience

The question of how many hertz displays the popular Xiaomi Redmi Note 9 Pro model has remained one of the most debated among potential buyers in the budget segment. Many users confuse the technical specifications, believing that modern smartphones must offer a high refresh rate by default.

It is worth noting that the Redmi Note 9 Pro is equipped with an IPS LCD matrix that operates at a standard frequency for its time. It is not 90 Hz or 120 Hz, as in the more expensive models of the Redmi Note line or Xiaomi Mi. Understanding this feature is critical if you choose a phone primarily for dynamic games or scrolling tape on social networks with maximum smoothness.

However, the lack of high hertz does not make the device bad, and the color calibration and brightness margin are well-suited to ensure comfortable use in most scenarios, and in this review we will take a closer look at the technical details, the effect of frequency on the battery and compare this parameter with competitors.

Technical characteristics of the display Redmi Note 9 Pro

The screen is based on Liquid Crystal Display technology, which is a classic solution for the mid-range price segment. The main advantage of this matrix is the natural color reproduction and no risk of pixel burnout, which is sometimes found in AMOLED panels in a static image. Resolution is 2400×1080 pixels, which at a diagonal of 6.67 inches gives a pixel density of 395 ppi.

The refresh rate is fixed at 60Hz. This means that the picture on the screen is updated 60 times per second. For comparison, standard monitors and TVs have also used this frequency for a long time. In the context of the smartphone 2020-2021, this was the norm, although competitors have already begun to implement 90Hz. For Xiaomi in this model, the priority was autonomy, not maximum smoothness of the interface.

An important aspect is the protective glass. This uses Gorilla Glass 5, which protects the matrix from scratches and light impacts. However, the lack of high hertz is compensated by good factory calibration. Users note that color reproduction in Standard mode looks most natural, while Saturated mode makes the colors brighter but less realistic.

What 60 Hz Means and How It Feels

60Hz screen refresh rate is the industry standard, and it feels like the standard smoothness that most users are used to. If you switch from another smartphone released before 2019, you probably won't notice the difference. However, after using a 90Hz or 120Hz device, the Redmi Note 9 Pro interface may seem a little less responsive when swiping fast.

In everyday tasks like reading the news, watching videos or listening to music, the difference between 60 and higher frequencies is virtually imperceptible. MIUI animations are optimized to look smooth even at a standard frequency. Problems can only occur in very dynamic scenes where objects move at high speed.

Some users with a flicker sensitivity may be better able to tolerate 60Hz IPS LCDs, as they are less likely to use PWM at low brightness levels than some AMOLED screens, making the phone safer for the eyes when reading long-term.

• 📱 Standard smoothness of page scrolling and menu.
• 🎮 In games, the limit is 60. FPS (frames per second is the norm for most mobile projects.
• 👁️ Less strain on the eyes with long-term use compared to cheap AMOLED.
• ⚡ Reduced power consumption compared to high hertz screens.

⚠️ WARNING: If you plan to use a smartphone for professional eSports in mobile shooters, the lack of 90Hz or 120Hz can be a limiting factor, as you won’t be able to see more frames per second than the screen allows.

The Effect of Screen Frequency on Autonomy

One of the main arguments for 60 Hz is energy efficiency: the screen is the most energy-intensive element of a smartphone. The 60 Hz matrix consumes significantly less power than the panels with an increased refresh rate. This directly affects the life of the Redmi Note 9 Pro on a single charge.

In combination with a large battery on 5020 mAh, the standard hertz allows the device to hold on to two days with moderate use. 90 Hz or 120 Hz, the battery life would be reduced by 15-20%, Which would make the phone less attractive to those who rarely have charging on hand.

The Snapdragon 720G processor installed in this model does a great job of rendering graphics at 60 frames per second without overheating. This creates a balanced system where no component is running at its limits, which positively affects the durability of the device.

Comparison with competitors and other Xiaomi models

To understand the Redmi Note 9 Pro’s market position, you need to compare it to other devices. While this model has stayed at 60Hz, more expensive versions like the Redmi Note 9 Pro Max or Redmi Note 10 have already received improved displays, which creates a certain hierarchy within the lineup.

Rivals from Realme and Samsung in the same price segment also often offered 60 Hz, but some models, such as the Realme 6 Pro, already boasted 90 Hz. This made them more attractive to gamers, although Xiaomi compensated for this with a more powerful processor and fast charging bundle.

Below is a table comparing the screen specs of the Redmi Note 9 Pro with its direct competitors and successors:

The table shows that the Redmi Note 9 Pro was not the leader in refresh rate, but offered reliable glass protection, which is often more important for the durability of the device. AMOLED In the next generations, the company responded to user requests.

Screen settings in MIUI for Redmi Note 9 Pro

Despite a fixed frequency of 60Hz, the MIUI shell offers a number of settings to improve visual perception.The user can adjust the color temperature to make the image warmer or colder. This is especially useful for those who spend a lot of time reading text.

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

1. Paper mode: adds a yellowish tint to reduce eye strain.

2. Dark Mode: Inverts the interface colors for use in the dark.

3. font size: allows you to adapt the text to your vision.

Also worth mentioning is the DC Dimming (or anti-flickering) feature, which can be activated in the Developer Menu or through a special security app, which helps reduce screen flickering at low brightness, which is relevant for IPS arrays.

For maximum color reproduction in the screen settings, select Standard. Saturated Colors can distort the shades when viewing photos.

Gaming experience on the 60 Hz screen

For mobile gamers, 60Hz means you can see a maximum of 60 frames per second. Most optimized games, such as PUBG Mobile or Call of Duty Mobile, on a Snapdragon 720G processor run consistently at high graphics settings in this range.

The absence of 90Hz does not give you a competitive advantage in shooters, but it does not make the game impossible. The response of the touchscreen in the Redmi Note 9 Pro is 180Hz (touch poll frequency), which provides a quick response to your actions, which means that the delay between pressing and action is minimal, even if the picture is updated 60 times per second.

Importantly, for long gaming sessions, the screen is not prone to overheating, which sometimes happens with higher frequencies.FPS (frames per second) stability here is higher than on many 90-hertz competitors, which can reset frequency when heated.

• 🎯 Stable 60. FPS scoring.
• 🖐️ The 180 Hz touchscreen survey frequency provides good responsiveness.
• 🌡️ Absence of overheating of the matrix with prolonged load.

⚠️ Note: In some heavy games, a default limit of 30 or 40 may be set. FPS Check the graphics settings inside the app itself to activate High or Ultra mode to get 60 FPS.
