About RefreshRateTest

At RefreshRateTest, our mission is to provide users with a highly accurate, browser-based utility to measure and verify their monitor's true refresh rate and frame smoothness.

In an era where high-refresh-rate displays are becoming the standard for both gaming and professional workflows, knowing that your hardware is performing as advertised is critical. Often, operating system settings, driver issues, or faulty cables can prevent a monitor from reaching its maximum potential.

We built this tool to bridge that gap. By utilizing modern web APIs like requestAnimationFrame, we can accurately calculate the rate at which your browser is painting frames to the screen. This provides a reliable, real-world measurement of your display's performance without the need to download or install third-party software.

Our Commitment to Accuracy

While browser-based tests are subject to certain limitations imposed by the operating system and browser engine, we strive to provide the most precise measurement possible. Our "Sync-Box" visual test allows you to physically verify the smoothness of the rendered frames, ensuring that the numbers you see translate to the performance you feel.
