Why verify your Hz?
Many gamers buy 144Hz or 240Hz monitors but forget to enable high refresh rates in Windows Display Settings or Nvidia/AMD Control Panels. If this tool shows "60Hz" on a gaming monitor, you are likely losing a significant competitive advantage.
How it works
This tool uses the requestAnimationFrame API to measure exactly how often your browser
tries to paint a new frame. By averaging these intervals over hundreds of cycles, we can determine your
hardware refresh rate with high accuracy.
