Accurately measure your display refresh rate (Hz) and test animation smoothness. Visual FPS counter shows real-time frame rate, helping you verify if your display is running at its advertised refresh rate. Useful for gaming or high-refresh-rate monitor verification.
Standard displays run at 60Hz (60 frames per second), while gaming monitors can reach 144Hz, 240Hz, or even 360Hz. Higher refresh rates reduce motion blur and input lag, making them essential for competitive gaming. This tester helps you verify if your display is actually running at its advertised refresh rate.
