What is refresh rate? 60Hz vs 144Hz vs 240Hz explained
Refresh rate is how many times a second your monitor redraws the screen, measured in hertz (Hz). A 60Hz panel shows up to 60 frames per second; a 144Hz one up to 144. Higher refresh means smoother motion and lower latency — but only if your GPU can produce the frames to fill it.
That last part is the catch most buying guides skip. A high-refresh monitor and a high frame rate are two halves of the same upgrade; one without the other does little. Here's what the numbers mean and whether the jump is worth it for you.
What does Hz actually mean?
One hertz is one refresh per second, so 144Hz means the screen redraws 144 times a second. That sets a ceiling on how many distinct frames you can possibly see: no matter how many your graphics card renders, a 60Hz monitor can only show 60 of them per second. Push past that ceiling and the extra frames are either discarded or cause screen tearing unless you sync them.
60Hz, 144Hz, 240Hz — what each is for
Refresh rate vs frame rate — the key distinction
These get mixed up constantly. Frame rate (fps) is how many frames your GPU produces; refresh rate (Hz) is how many your monitor can display. You only ever experience the lower of the two. A graphics card rendering 144 fps on a 60Hz screen still shows 60; a 240Hz monitor fed only 50 fps still looks like 50. To benefit from high refresh, both numbers have to be high — which is exactly the relationship we break down in our good FPS guide.
Is a high-refresh monitor worth it?
For most people, yes — going from 60Hz to 144Hz is one of the most noticeable upgrades in PC gaming, and human vision keeps benefiting from higher frame rates well past 60, with diminishing returns above that (How-To Geek). But it's only worth it if your GPU can fill it.
This is where matching matters. A Ryzen 5 7600 + RTX 4070 pushes around 240 fps in Counter-Strike 2 — perfect for a 240Hz panel — but about 86 fps in Cyberpunk 2077, where a 144Hz monitor is plenty and 240Hz would sit half-empty. Match the monitor to the frame rates you'll actually hit in the games you play, not to the biggest spec. You can check yours, game by game, in our FPS calculator.
Don't confuse refresh rate with response time
They sound similar but measure different things. Refresh rate (Hz) is how often the screen updates; response time (in milliseconds) is how fast a pixel can change colour. A high refresh rate with a slow response time still smears in motion. Both matter for a clean fast-motion image, so don't read one number and assume the other.
What you need to drive high refresh
A high-refresh monitor is a GPU commitment. In light or competitive games, even a mid-range card clears 144 fps easily; in demanding ones you'll lean on upscaling and a few settings tweaks to get there. And to avoid tearing when your frame rate sits below the refresh, pair it with a variable-refresh feature (G-Sync or FreeSync) and an in-game frame cap. Get the frame rate first; the monitor only pays off once you can feed it.
Frequently asked questions
Is 144Hz worth it?
For most gamers, yes — the jump from 60Hz to 144Hz is the most noticeable smoothness upgrade you can buy, in both fast and slow games. The catch is that you need a GPU that can actually push high frame rates in your games to feel the benefit.
Do I need a good GPU for 144Hz?
To get the most from it, yes. A 144Hz monitor only helps if your GPU produces frame rates near 144 — otherwise you are paying for refresh you cannot fill. In demanding games you may need upscaling or lower settings to get there.
Is 60Hz enough for gaming?
It is perfectly playable and fine for single-player and slower games. But once you have seen 120Hz or 144Hz, 60Hz feels noticeably less smooth, especially in fast motion. For competitive play, higher refresh is a real advantage.
What is the difference between refresh rate and frame rate?
Frame rate (fps) is how many frames your GPU produces; refresh rate (Hz) is how many your monitor can display per second. You only see the lower of the two — a 144 fps GPU on a 60Hz screen still shows 60, and a 240Hz monitor fed 50 fps still looks like 50.
Is 240Hz better than 144Hz?
Technically yes, but the difference is subtle and mostly matters for competitive shooters. The 60-to-144 jump is dramatic; 144-to-240 is a refinement that trained players notice more than casual ones.
Before you buy a 144Hz or 240Hz monitor, check what frame rate your build actually hits.
