Key Takeaways
- Refresh rate measures how many times per second your screen redraws its image, expressed in hertz (Hz).
- 60Hz is standard for most everyday computing and casual video watching.
- 120Hz or higher makes a noticeable difference for gaming, scrolling, and fast-action video.
- The display's refresh rate and the content's frame rate both need to be high for maximum smoothness.
- For typical office work or streaming, a higher refresh rate offers diminishing returns.
Refresh Rate
Refresh rate is the number of times per second a display redraws the image on screen, measured in hertz (Hz). A 60Hz screen updates 60 times every second; a 120Hz screen updates 120 times. Higher refresh rates generally produce smoother-looking motion, especially during fast-moving content like gaming or sports video.
Refresh rate is a property of the display panel itself — it sets the ceiling for how smooth motion can appear, but the content source (game engine, video file, or video signal) must also output frames at a matching or higher rate for the benefit to be fully realized.
The Basics: What Hz Actually Means
Every display — phone, monitor, TV, or laptop — refreshes its image continuously. The number of times it does this each second is its refresh rate, and it's measured in hertz (Hz). A screen running at 60Hz redraws the picture 60 times per second. One running at 144Hz does it 144 times.
This matters because the human visual system perceives rapid image updates as continuous motion. When a screen refreshes quickly enough, individual frames blend together and movement appears fluid rather than choppy. When refresh rate is too low relative to the motion on screen, you may notice blur, judder, or a stuttering quality — particularly in fast sequences.
It's worth pairing this concept with an understanding of resolution, since both shape your overall visual experience. See our guide to screen resolution terms for how pixel counts factor into the picture.
60Hz
Standard refresh rate for most displays
60Hz has been the baseline for consumer monitors and TVs for decades and remains common across mid-range devices.
120Hz
Common threshold for high-refresh displays
120Hz panels are now standard on many flagship smartphones and gaming monitors, representing the most widely adopted step up from 60Hz.
24 fps
Standard cinematic frame rate
Most theatrical films are shot and distributed at 24 frames per second, meaning cinema content doesn't inherently benefit from very high display refresh rates.
When Refresh Rate Makes a Real Difference
For most everyday computing — email, word processing, browsing — a standard 60Hz screen is perfectly adequate. The human eye doesn't gain much from faster updates when content itself isn't moving quickly.
The calculus changes in three key scenarios:
- Gaming: Fast-action games generate many frames per second and benefit significantly from displays that can keep pace. At 120Hz or higher, on-screen motion is visibly smoother, and the window between a frame being rendered and displayed shrinks.
- Scrolling: Even outside games, a higher refresh rate makes scrolling through web pages or social feeds feel noticeably more fluid — this is why flagship smartphones have moved aggressively toward 90Hz and 120Hz panels.
- Sports and action video: Live sports broadcast at higher frame rates (typically 60 frames per second) can look sharper and more lifelike on a higher-Hz display than on a 60Hz panel.
Match Your Use Case to the Right Hz
Before prioritizing a high refresh rate, consider what you'll actually do with the screen. Gamers and heavy scrollers gain the most from 120Hz and above. For video streaming and productivity work, 60Hz is usually sufficient and often found at more accessible price points.
Refresh Rate vs. Frame Rate: Why Both Matter
A common point of confusion is treating refresh rate and frame rate as the same thing — they're related but distinct. Refresh rate is a hardware ceiling set by the display. Frame rate is the number of individual images a video source or game engine produces each second.
If a game produces 120 frames per second but your monitor only refreshes at 60Hz, you're only seeing 60 of those frames — the display becomes the bottleneck. Conversely, a 144Hz monitor connected to a source producing only 30 frames per second will still only show 30 distinct images per second, regardless of how fast the screen can refresh.
Technologies like variable refresh rate (VRR) — including standards such as AMD FreeSync and NVIDIA G-Sync — help by dynamically synchronizing the display's refresh rate to the game engine's output, reducing screen tearing and stutter. These are display features worth understanding when evaluating a monitor or TV for gaming use.
For streaming content, the picture is simpler but still nuanced. Most films run at 24 frames per second, so a high refresh rate doesn't directly add cinematic smoothness. Learn more about how video quality labels interact with your experience in our explainer on 4K, HDR, and Dolby Vision.
Motion Smoothing Is Not the Same as Refresh Rate
Many TVs advertise effective refresh rates using terms like "motion rate" or "effective Hz" that reflect post-processing, not the panel's native hardware rate. These figures can be misleading — always look for the native refresh rate specification when evaluating a display's true capability.
How to Think About Refresh Rate When Choosing a Display
Rather than chasing the highest Hz number on a spec sheet, it helps to match refresh rate to actual use. For office work, media consumption, and casual browsing, 60Hz remains serviceable and is common on budget and mid-range displays. For gaming — especially action-heavy or competitive titles — 120Hz to 165Hz is a meaningful upgrade. Anything above that tends to deliver diminishing returns for all but the most demanding use cases.
Smartphone screens have shifted rapidly. Many current flagship phones offer 120Hz displays with adaptive refresh, meaning the screen drops to lower rates for static content to conserve battery and ramps up when scrolling or gaming. This adaptive approach delivers smoothness where it's perceptible without constant power draw.
Refresh rate is one specification among several — alongside resolution, panel type, and color accuracy — and understanding how they interact gives you a clearer picture of what a display will actually feel like in daily use.
