Is your monitor actually hitting the Hz on the box?

Manufacturers advertise a refresh rate, but cables, settings, and display modes can quietly cap it lower. This measures what your browser is actually seeing, right now.

Common refresh rates and where they matter

Refresh rateWhat it means
60HzStandard office monitors and most budget laptops.
75HzA modest step up over 60Hz, common on entry gaming monitors.
90HzIncreasingly common on mid-range phones for smoother scrolling.
120HzFlagship phones and mid-tier gaming monitors alike.
144HzThe long-standing baseline for gaming monitors.
165–240HzCompetitive shooters where every frame's timing counts.
360Hz+Niche esports panels chasing the last few milliseconds.

Why this behaves this way

FPS vs Hz

FPS is what the GPU renders; Hz is how often the screen redraws. A 240Hz monitor showing a 60fps game still refreshes 240 times a second, redrawing the same frame repeatedly until the next one is ready.

Why the cable and settings matter

A monitor's maximum Hz is only reachable with the right cable and the right operating-system display setting. Some HDMI versions cap out below DisplayPort. It is common to buy a 144Hz monitor and find the system quietly defaulted to 60Hz after a driver update.
