How to check the screen frequency on RedmiBook 9

If you already own RedmiBook 9 and want to make sure you update your screen, there are a number of ways to do this: First, Windows has built-in tools to view this information; and second, you can use third-party utilities that provide more detailed data.

2. Go to the System → Display → Additional display parameters.
3. In the Display Adapter Properties block, select the List of all modes.
4. The window that opens will indicate the resolution and refresh rate (e.g., 1920×1080, 60Hz).

If this method did not work (for example, because of drivers), use third-party programs:

• 🔧 NVIDIA Control Panel (if you have a video card) NVIDIA) — Shows available frequencies in the Change permission section.
• 🖥️ AIDA64 — in the section Display → The monitor displays the current and maximum frequency.
• 📊 TestUFO (online test) – a site for visually checking the smoothness of the screen.

Open Windows Settings (Win + I)| Go to System → Display → Additional Settings | Check the list of all modes | Use AIDA64 for detailed information-->

⚠️ Some users are trying to “accelerate” the screen to the 75 Hz or higher via driver settings Intel/AMD/NVIDIA. This can lead to image artifacts, flickering or even damage to the matrix.RedmiBook 9 hardware does not support frequencies higher 60 Hz!

60Hz vs 120Hz: Should you pay too much for high frequency?

The refresh rate is the number of frames that a display can display per second. The higher that value, the smoother the movement on the screen looks. But is it you who need a high frequency? Let's compare 60 Hz (like the RedmiBook 9) and 120 Hz (like gaming laptops):

• 🎯 For office work and study, 60 Hz is more than enough, and the difference from 120 Hz will be invisible when reading texts or working with tables.
• 🎮 For gaming: 120Hz gives an advantage in dynamic shooters (CS:GO, Valorant, Fortnite, where reaction is important. RPG minimum difference.
• 🎬 For video viewing: Most movies and TV shows are shot at 24-30 frames / s, so 60 Hz is enough. FPS (For example, on YouTube, 120 Hz will be a plus.
• 🖌️ For design and drawing: High frequency is useful when working with animation or 3D-models where smoothness of the display is important.

Note that laptops with a screen of 120 Hz and above are usually:

• ⚡ Consume more energy, which reduces battery life.
• 💰 Cost more (the difference can reach 15-20 thousand rubles).
• 🔥 Requires a more powerful graphics card to "push" the high FPS play.

💡

For most tasks, 60Hz on RedmiBook 9 is enough. It is only for gamers or professionals working with dynamic graphics to overpay for 120Hz.

Can I increase the screen frequency on RedmiBook 9 software?

Many users are wondering: can you overclock the screen to 75 Hz or 120 Hz through driver settings or special utilities? Unfortunately, this is not possible on RedmiBook 9. The refresh rate is rigidly embedded in the hardware of the display, and it can not be changed software.

• 🔧 NVIDIA/AMD Control Panel – will not give results, as the list of available frequencies will be only 60 Hz.
• 🖥️ Custom Resolution Utility (CRU) — This can cause the screen to work unstable or to shut down.
• 📋 Windows Registry Editing – Will Not Affect Hardware Restrictions.

The only way to get a higher frequency is to connect an external monitor with support for 120 Hz or 144 Hz via HDMI or USB-C. For example, RedmiBook 9 supports displaying images on external displays with a frequency of up to 144 Hz (if you have the appropriate cable and monitor).

⚠️ Warning: If after experimenting with screen settings, the image is missing or artifacts appear, reset the display drivers. To do this: Load into Safe Mode (hold Shift when rebooting). Delete the graphics drivers through Device Manager. Install drivers again from the official website Intel/AMD/NVIDIA.

RedmiBook 9 compared to other Xiaomi laptops by screen frequency

If 60Hz on RedmiBook 9 doesn’t suit you, consider other Xiaomi models with higher refresh rates. Below is a comparison table of the brand’s current laptops (2026):

As you can see from the table, RedmiBook 9 loses in refresh rate to newer models, but benefits in price and autonomy. If you need a laptop solely for document work, programming or watching videos, 60 Hz will be the best choice. For games or professional graphics work, you should consider RedmiBook 16 (144 Hz) or Xiaomi Gaming Laptop.

The Effect of Screen Frequency on Autonomy and Performance

One of the key questions when choosing a laptop is how the screen frequency affects battery life and performance.

• 🔋 Autonomy: A 120Hz screen consumes 20 to 30 percent more power than a 60Hz screen. For example, a 60Hz RedmiBook 9 will run on a single charge. ~8-10 hours (in office mode), whereas a laptop with 120 Hz – only 5-6 hours.
• 🎮 Gaming performance: To take advantage of 120Hz, a graphics card must deliver 120 FPS Built-in graphics Intel Iris Xe or AMD Radeon Graphics in RedmiBook 9 rarely exceeds 60 FPS In modern games, a high screen frequency would be useless.
• 🖥️ Heat: Higher refresh rate increases the load on GPU, RedmiBook 9 with 60 Hz stays colder when running for long periods of time.

If autonomy is critical for you (like you’re often on the road), then the RedmiBook 9 with its 60-hertz screen will be a smarter choice than the 120Hz models. However, if you plan to plug your laptop into the outlet most of the time (like for gaming at home), a high frequency can prove useful.
