Why this tool is useful
Your monitor refresh rate, measured in Hz, determines how many times per second the display can update its image. This directly impacts the smoothness of animation, scrolling, video playback, and gaming. A 60Hz monitor updates 60 times per second; a 144Hz monitor updates 144 times. This test accurately measures your display effective refresh rate using high-speed frame detection, helping you verify whether your monitor is running at its rated maximum frequency or if driver, cable, or settings issues are causing it to run at a lower rate.
