1.The official screen specs of the Redmi Note 9: what Xiaomi says

According to the manufacturer, Xiaomi Redmi Note 9 (model M2003J15SS for the global market) equipped IPS-diagonal 6.53 inch and resolution 2340 ร— 1080 pixels (Full) HD+). The screen refresh rate is fixed at the level 60 Hz. That's confirmed:

  • ๐Ÿ“„ Official Xiaomi website (specification section for the model)
  • ๐Ÿ“ฆ Documentation in the device box
  • ๐Ÿ”ง Technical data in the service menu of the smartphone (we will talk about them below)
  • ๐Ÿงช Independent tests from GSMArena, NotebookCheck and other reputable resources

Itโ€™s important to understand that 60Hz is the standard frequency for most budget and mid-range 2020 smartphones, providing smooth scrolling, comfortable video viewing, and adequate touch response. However, for dynamic games or high frame rate content (e.g., 120-frequency video) FPS) That may not be enough.

โš ๏ธ Note: There are variations of the Redmi Note 9 for different regions (India, China, Europe) in some of which there may be minor differences in the firmware, but the screen frequency remains 60 Hz in all versions of the base model.

2. How to check the screen frequency on Redmi Note 9

If you're in doubt about your device's specifications, or if you want to make sure that the seller hasn't misled you, there are a few ways to check the actual screen refresh rate, all of which are free and don't require root rights.

Method 1: Through the Engineering Menu

This is the most reliable method, as the data is taken directly from the system:

  1. Open the Phone app and enter the combination: ##4636##.
  2. In the menu that appears, select Hardware Testing (or Hardware info).
  3. Scroll down to the Display section โ€“ there will be a Refresh rate bar with the current value.

Method 2: Applications for testing

Google Play has a tool that shows the frequency of the screen in real time.

  • ๐Ÿ“ฑ Display Tester โ€“ shows not only the frequency, but also other screen parameters (color gamut, reaction to touches).
  • ๐Ÿ” Screen Refresh Rate is a minimalist application with a single screen and a Hz number.
  • ๐Ÿ“Š CPU-Z โ€” In the Device section, displays information about the display.

When using third-party apps, consider that some may be the highest possible frequency, not the current one. For example, if your smartphone supports adaptive frequency (as in newer models), the application can output 90 Hz, although the screen actually runs at 60 Hz.

Method 3: Visual Test with Camera

This is a โ€œold-fashionedโ€ method that works without software, but requires a second camera (for example, from another smartphone):

  1. Turn on the Redmi Note 9 white image on the full screen (you can open an empty document in Google Docs).
  2. Point the camera of another phone to the screen and make a video in slow-motion.
  3. When you play the video, you'll see the screen flicker. Count the number of flashes per second, and that's the frequency in Hz.

โš ๏ธ Note: This method is approximate and may give an error ยฑ5 Hz. Use the first two methods for accurate data.

3.60Hz vs 90Hz: How critical the difference is for the Redmi Note 9

Many users worry that 60Hz is โ€œlittleโ€ compared to todayโ€™s 90Hz or 120Hz smartphones. Letโ€™s see how important this is in everyday use.

Pros of 60 Hz:

  • โšก Energy efficiency: the screen consumes less energy, which has a positive effect on battery life.
  • ๐Ÿ’ฐ Below the price: smartphones with 60 Hz are usually cheaper than high-frequency counterparts.
  • ๐ŸŽฌ Content Compatibility: Most videos and games are optimized for 60Hz (Netflix, YouTube, most mobile games).

60 Hz downsides:

  • ๐ŸŽฎ Less smoothness in dynamic games (e.g, PUBG Mobile or Call of Duty: Mobile).
  • ๐Ÿ“ฑ Less responsive interface when scrolling fast (for example, in TikTok or when leafing the tape in social networks).
  • ๐Ÿ‘€ Eye fatigue with prolonged use due to less smooth picture.

In practice, the difference between 60 Hz and 90 Hz is not noticed by all users. According to the study by Android Authority, only 30% of respondents were able to distinguish 90 Hz from 60 Hz in a blind test without prompts. 8T), Getting back to 60 Hz can be frustrating.

7. Frequent Myths About Redmi Note 9 Screen Frequency

There are a lot of myths surrounding the Redmi Note 9 screen frequency, and we'll take a look at some of the most common ones and figure out what's true and what's fiction.

Myth 1: โ€œIn some regions, the Redmi Note 9 comes from 90Hz.โ€

๐Ÿšซ Reality: No, in all official versions of the Redmi Note 9 (including the Indian version) M2003J15SI global M2003J15SS) The confusion arises due to the fact that in some countries, called Redmi Note 9 sold Redmi Note 9 Pro (for example, in Indonesia).

Myth 2: โ€œAfter the MIUI update, the screen is running at 90 Hz.โ€

๐Ÿšซ Reality: Firmware updates can't physically change the frequency of the matrix. If the 90Hz option appears in the settings after the update, it's either an interface bug or a bogus option (as in some custom firmware).

Myth 3: 60 Hz damages the eyes more than 90 Hz

๐Ÿšซ Reality: There is no scientific evidence that 60Hz is more harmful to vision. Eye fatigue depends on many factors: brightness, contrast, time of use and individual characteristics. 90Hz can reduce fatigue when working with dynamic content for a long time (for example, text scrolling), but the difference is not critical.

Myth 4: Redmi Note 9 supports adaptive screen frequency

๐Ÿšซ Reality: Adaptive frequency (automatic switching between 60Hz and 90Hz) only appeared in newer Xiaomi models, starting with the Redmi Note 10 (2021.
