Close heavy apps, run the test for at least 30 seconds, and compare the measured FPS with your monitor's selected Hz. Browser results verify display and rendering timing; they do not replace an in-game FPS counter.
A 60Hz display commonly reports about 60 FPS, a 144Hz display about 144 FPS, and a 240Hz display about 240 FPS when the browser, operating system, cable, and graphics settings allow it. Small fluctuations are normal.
Check Windows display settings, the monitor's on-screen menu, the cable and GPU output, browser hardware acceleration, and whether another display is limiting the refresh rate.
