144Hz vs 60Hz: Does Refresh Rate Actually Matter?

Refresh rate is how many times per second your display draws a new image — 60Hz means 60 frames every second, 144Hz means 144. More frames per second means each frame shows a smaller slice of motion, so movement looks smoother, fast-moving objects stay legible instead of smearing, and the delay between your input and its on-screen result shrinks.

That last point is subtle but real: at 60Hz, a frame is displayed for 16.7 milliseconds, so on average your click waits ~8ms just for the next refresh — before any other latency. At 144Hz the frame time is 6.9ms; at 240Hz, 4.2ms. Competitive players feel this as responsiveness, not just smoothness.

The jump from 60Hz to 120–144Hz is dramatic — nearly everyone perceives it immediately, even just dragging windows or scrolling text. From 144Hz to 240Hz the improvement is real but much smaller, mainly noticed in fast competitive play. Beyond 240Hz, differences are measurable and matter to professionals, but most people can't reliably pick them out.

Two caveats. First, your GPU must actually produce the frames — a 144Hz monitor showing a game running at 60fps gains little. Second, response time (how fast pixels change color) matters alongside refresh rate; a slow panel smears motion regardless of Hz. For everyday desktop work, meanwhile, 60Hz remains perfectly fine — high refresh is a comfort upgrade there, not a necessity.

Buying a high-refresh monitor doesn't make it run at high refresh. Operating systems frequently default to 60Hz, cables are a silent culprit (older HDMI versions can't carry 1440p at 144Hz — DisplayPort is the safe choice), and OS or driver updates occasionally reset the setting. An enormous number of high-refresh monitors are running at 60Hz right now, their owners none the wiser.

The check takes ten seconds: open the refresh rate test on this site, let it stabilize for a few readings, and compare the measured value against what you paid for. If it reads ~60 on a 144Hz panel, fix it in Windows under Settings → System → Display → Advanced display (choose the refresh rate), or on macOS under System Settings → Displays.
