Why the Redmi Note 9 Pro screen became a benchmark in the budget segment

Smartphone Xiaomi Redmi Note 9 Pro was released in 2020 and immediately attracted attention not only powerful processor Qualcomm Snapdragon 720G, But it's also a screen that many experts have called the best in its price range, and in an era where even flagship devices are saving on displays, the Redmi Note 9 Pro offered users the best screens ever. IPS-supporter HDR10 and brightness up to 450 nits - characteristics that were previously the prerogative of devices twice as expensive.

But what exactly is behind the marketing slogans? What type of screen is used in this model, what are its real pros and cons, and is it worth choosing this smartphone today (2026) because of the display? In this article, we will analyze the technical specifications, test the screen for strength in everyday scenarios and compare it with competitors from the Samsung Galaxy M31 to the Realme 6 Pro. If you are planning to buy or just interested in technology, this information will help make an informed choice.

Technical characteristics of the screen Redmi Note 9 Pro: disassemble by item

Let’s start with the “dry” numbers. the screen Xiaomi Redmi Note 9 Pro has the following key parameters:

• 📏 Diagonal: 6.67 inches (16.94 cm) – classic size for multimedia tasks.
• 🔍 Permission: 2400 × 1080 pixels (Full) HD+), point-density — 395 PPI.
• 🔄 Frequency of update: 60 Hz (no support) 90/120 Hz, like the newer models).
• 🎨 Type of matrix: IPS LCD technologic TÜV Rheinland Low Blue Light (certification for reducing harmful blue radiation).
• 🌈 Color gamut: 96% NTSC (More than many competitors in this segment).
• 🛡️ Protection: Gorilla Glass 5 (resistant to scratches and falls from a height of up to 1.6 m).

Particularly worthwhile is the support HDR10 — This is a rare option for budget smartphones, which means that when you watch videos from the Internet. HDR-With content (such as Netflix or YouTube), the screen will be able to display a wider dynamic range, improving the details in dark and light scenes. HDR Not only does it require display support, but it also requires compatible content and sufficient lighting (in bright sunlight, the effect will be less noticeable).

Another important thing is brightness: the manufacturer claims a maximum of 450 nits, but in real tests (for example, from GSMArena or NotebookCheck), the screen shows about 420-430 nits when adjusting automatically. IPS-They're not very good at lighting up, but they're not good enough for comfortable use in the bright sun, and you're going to have to increase the brightness by hand or look for shadow.

IPS vs AMOLED: Why Xiaomi chose LCD for the Redmi Note 9 Pro

Many users are wondering why Xiaomi has not installed AMOLED-The screen in the Redmi Note 9 Pro, as competitors have done (e.g. Realme 6 Pro with Super) AMOLED)? The answer lies in the balance between price, reliability and performance.

The IPS LCD capabilities used in this model are:

• ✅ Durability: IPS-Matrices are less prone to pixel burnout (problem) AMOLED) and degradation over time.
• ✅ Color reproduction: more natural colors "out of the box" (without excessive saturation, as in the case of the AMOLED).
• ✅ Cost: Production IPS-Desplay cheaper, which allowed to meet the budget price of the smartphone.
• ❌ Contrast: black on the color IPS — It's "dirty" gray. AMOLED — perfect-black).
• ❌ Energy consumption: LCD-panels consume more energy when displaying dark themes (AMOLED cost-effectively).

Interestingly, in later Redmi Note series models (such as Note 10 Pro or Note 11 Pro+), Xiaomi has switched to AMOLED, suggesting that the IPS choice for the Note 9 Pro was more of a marketing ploy to make production cheaper without critical quality loss. For most users, the difference between IPS and AMOLED in everyday tasks (social networks, videos, games) will be negligible, especially if you don’t compare them directly.

Real Tests: How the Screen Behaves in Games, Videos, and the Sun

The specs are good, but how does the Redmi Note 9 Pro display in real-world scenarios?

1. Games: PUBG Mobile and Call of Duty: Mobile, with maximum graphics settings, displays a stable 60 FPS without artifacts. However, due to the lack of a high refresh rate (90/120 Hz), the animation seems less smooth compared to the flagships, but there is no problem with the touch sampling rate - 180 Hz, which provides a quick response to touch.
2. Video: When viewed HDR-content on YouTube or Netflix, the difference AMOLED noticeable - black color is not so deep, but there is no effect of "burning out" of static elements (as on the black color). AMOLED It's bright enough for a comfortable viewing indoors, but outside in the bright sun you have to cover the screen with your hand.
3. Reading and surfing: High pixel density (395) PPI) The text is clearly displayed, without "pixelation." The white substrate in the browser or books looks natural, without yellowness (a problem of some people). AMOLED-screen).

The algorithm in the Redmi Note 9 Pro works well, but sometimes misses — for example, in the dark it can dim the backlight too much, forcing the user to adjust it manually, a problem that is common in many MIUI-based smartphones, and is solved either by turning off autobrightness or installing third-party apps like Lux Auto Brightness.

💡

If you don't have enough brightness in the sun, turn on the Contrast Amplifier mode (Settings → Screen → Contrast Amplifier) in your settings. This will improve readability a little, although it won't replace a full AMOLED.

Comparison with competitors: who offers the best screen in this segment?

To objectively evaluate the screen Redmi Note 9 Pro, compare it with the main competitors of 2020-2021 in the price range up to 25 000 rubles.

The table shows that the Redmi Note 9 Pro is in the middle: it loses the Realme 6 Pro in matrix type and refresh rate, but wins over the Samsung Galaxy M31 by supporting HDR10 and a newer protective glass. The main advantage of the Redmi screen is the balance: it has no critical shortcomings and is suitable for the majority of users who do not chase the maximum specs.

If you’re looking at a really high refresh rate of 120Hz, you should look at the POCO X3 NFC, which is built on the same platform but offers smoother scrolling, but note that at 120Hz, battery life is reduced by 15-20%.

💡

Redmi Note screen 9 Pro is the best choice for those who appreciate balanced characteristics: good color reproduction, support HDR10 and reliability IPS-If you want maximum smoothness or deep black, consider models with AMOLED frequency 90/120 Hz.
