Questions
Why does it say 60 Hz on my 144 Hz monitor?
The display may be set to 60 Hz in your system settings, the cable or port may not support the higher rate, or a power-saving mode may be limiting it. Check the display settings first.
Does variable refresh rate (G-Sync/FreeSync) change the result?
VRR follows the frame rate of games; in a browser you normally see the display’s maximum. On laptops and phones, battery saving can lower it.
How is this different from the FPS test?
This page measures what your display can show. The FPS test stresses the browser to see how many frames it can actually draw and how smooth they are.
