Monitor Refresh Rate, Explained
Refresh rate, in hertz, is how many times per second a screen draws a new image; a 120Hz screen redraws twice as often as a 60Hz one.

The short answer
The refresh rate is how many times per second a screen draws a new image. It is measured in hertz (Hz). NIST, the US measurement agency, defines the hertz as one cycle per second, so a 60Hz monitor redraws the picture 60 times every second and a 240Hz monitor 240 times.
A higher rate makes motion look smoother, which matters most in fast games. It only helps when the computer sends that many frames: a game running at 60 frames per second looks the same on a 60Hz and a 144Hz screen.
The math behind the number
Divide one second by the refresh rate to get the time each image stays on screen:
| Refresh rate | Time per image |
|---|---|
| 60Hz | about 16.7 milliseconds |
| 120Hz | about 8.3 milliseconds |
| 144Hz | about 6.9 milliseconds |
| 240Hz | about 4.2 milliseconds |
Going from 60Hz to 120Hz cuts that time in half. Each further step saves fewer milliseconds than the one before, which is why the jump from 60Hz feels larger than the jump from 144Hz to 240Hz.

Laptop screens use the same unit. On Wiki Shopping you can filter laptops with a 144Hz screen, laptops with a 120Hz screen and laptops with a 240Hz screen.
How to choose
- Office work and video. Text and still images do not change many times per second, so size, resolution and the stand may matter more to you here. The monitors for office work page groups that use.
- Fast games. A high refresh rate pays off when your graphics card can reach those frame rates in the games you play. The monitors for gaming page groups them.
- Check the connection. A monitor's inputs do not always all support its top rate. The maker's specification page lists which input supports which rate.
How we count
Each monitor on Wiki Shopping has its refresh rate read from the store listing. A monitor whose listing gives no rate is counted as "Not stated". Rates without a link have no public filter page yet. The counts change as listings are added or removed.
