What is the 120Hz Refresh Rate on Screens?

If you’ve gone to buy a phone or monitor lately, surely you’ve seen “120Hz” written in giant letters everywhere. But what does this number really mean? Is it pure marketing or is it the difference between a device that feels like it’s from 2026 and one that feels ten years old?

I won’t lie to you, the first time I switched from a normal screen to a 120Hz one, my brain took a couple of minutes to adjust, but after that, going back was impossible. In this article, I explain what the 120Hz refresh rate is and why it matters.

What is the 120Hz Refresh Rate: The Easy Explanation

Imagine that your phone screen is like one of those flip-books with drawings in the corners that, when you flip the pages fast, seem like the drawing moves.

The refresh rate is simply how many times per second that book flips a page. Almost all traditional screens are 60Hz (flipping 60 images per second). A 120Hz screen does it, literally, twice as fast.

What works for me to explain it is to compare it to a movie theatre: the faster the frames move, the smoother and more realistic everything looks.

Real Advantages of 120Hz in the Day-to-Day

Don’t think this is just for people who play online professionally. The benefits are noticeable in almost anything you do with the screen on.

Here comes the important part:

1. Fluidity When Scrolling: When reading Twitter (X), Instagram, or a web page, text and images move with smoothness like butter. There is no small “jump” or blurry trailing when scrolling down fast.
2. Immediate Response: When touching the screen, it seems the system reacts sooner. This is because the panel shows you the touch response much faster than an old one.
3. Less Eye Fatigue: Since the movement is more natural, the eyes have to make less effort to follow what occurs on screen.

Differences: 60Hz vs 90Hz vs 120Hz

To see the differences without reading boring manuals, I’ve prepared this comparison table:

That said, Option B is better for the majority: look for devices that have Adaptive Refresh Rate (LTPO). This technology lets the screen drop to 1Hz when you’re looking at a static photo and go up to 120Hz only when you’re touching or playing, saving a lot of battery.

Is it Worth Paying More for a 120Hz Screen?

Here comes my honest opinion. If you’re a user who only uses the phone for WhatsApp or reading the newspaper, maybe it’s not an absolute priority.

Spoiler: But if you spend more than an hour a day interacting with social media or playing games, the jump to 120Hz is the best hardware investment you can make nowadays. Much more than having more megapixels in the camera.

Once you get used to 120Hz, a 60Hz screen will seem broken or that the phone is “slow,” even if it isn’t.

120Hz for Content Creators and Video Editing

It’s not all about scrolling and gaming. If you create content for social media or edit video on your phone, 120Hz gives you an advantage that’s rarely mentioned: precision on the timeline.

When editing video in apps like CapCut or InShot, dragging clips on the timeline with a 120Hz screen is infinitely more precise. There’s no small delay or “jump” that makes you cut half a second before or after where you intended. For me, this makes the difference between a quick edit and one that takes twice as long.

Also, if you work with graphics or design on your phone (apps like Canva or Figma), the fluidity when moving elements around the screen makes the work much more comfortable. Your eyes get tired less and your productivity goes up.

144Hz and 240Hz Screens: Is It Worth Going Beyond?

In 2026 there are already phones and monitors that reach 144Hz, 165Hz, and even 240Hz. The obvious question is: can you tell the difference compared to 120Hz?

The honest answer is that the performance curve starts flattening out a lot after 120Hz. While the jump from 60Hz to 120Hz is like going from night to day, the jump from 120Hz to 144Hz is much more subtle. You’ll only notice it if:

• You’re a competitive gamer where every millisecond counts.
• You professionally work with animation or motion graphics.
• You have a particularly trained eye for detecting fluidity differences.

For the average user, 120Hz is the sweet spot between performance and battery consumption. Don’t feel obligated to chase higher numbers just because of marketing.

How to Check Your Current Screen’s Refresh Rate

If you’re not sure whether your device has 60Hz, 90Hz, or 120Hz, there are easy ways to check without searching for the model on Google.

On Android:

1. Go to Settings → Display.
2. Look for Refresh rate or Screen refresh rate.
3. You’ll see the available options (for example, 60Hz/120Hz or 60Hz/90Hz/120Hz).

On iPhone:

1. Go to Settings → Display & Brightness.
2. Look for ProMotion. If this option appears, your iPhone has adaptive refresh rate up to 120Hz.

On PC (Windows):

1. Right-click on the desktop → Advanced display settings.
2. Look for Refresh rate. The exact value in Hz will appear there.

Pro-tip: You can also use websites like TestUFO (testufo.com) from your phone or PC browser. It will show you exactly what Hz your screen is running at with a clear visual test.

120Hz and Accessibility: Does It Help People with Vision Issues?

An aspect that almost nobody mentions is the positive impact of 120Hz on people with certain visual difficulties. Smoother movement reduces the eye’s focusing effort, which can make a real difference for those who are sensitive to flickering or suffer from chronic eye strain.

If you spend many hours in front of a screen working or reading, combining 120Hz with comfort view mode (which reduces blue light) creates a much friendlier experience for your eyes. It’s not magic, but after eight hours of work you’ll notice the difference in how your eyes feel at the end of the day.

It also helps with reading long text: smooth scrolling makes the jump from line to line more natural, like reading a paper book instead of a document that “jumps.” For me, this has been especially useful when reading long articles or ebooks on my phone.

FAQ: Frequently Asked Questions

Does a 120Hz screen drain much more battery?

Yes, it drains between 10% and 20% more if you leave it fixed. That’s why it’s vital that the device has an intelligent mode or is an LTPO panel to adjust the speed to the content.

Is it noticeable on mobile the same as on PC?

It’s more noticeable on mobile because you’re touching the screen directly with your finger, but on PC it’s fundamental for fast-action video games where every millisecond counts.

Do all games work at 120Hz?

No. The game developer has to enable that option. Many heavy games still limit to 60Hz not to melt the phone’s processor.

Conclusion

Knowing what the 120Hz refresh rate is helps you understand why some devices feel so smooth and others seem sluggish. My verdict is clear: it’s the feature that defines a modern device. If you can afford it, always choose 120Hz; your eyes and your patience when navigating will thank you every second.
