Frequently Asked Questions

Why might my 144Hz monitor show 60Hz?
Display setting in OS, not just monitor capability. macOS often defaults to 60Hz even on ProMotion. Windows: Display Settings → Advanced → set 144Hz. Some HDMI cables max at 60Hz.
How accurate is the detection?
requestAnimationFrame fires at ≤display rate. After 300+ frames the average converges to true Hz ±0.5. Power-saving mode and other browser tabs can throttle below true rate.
Why does Chrome cap at 60Hz sometimes?
Battery saver, low power mode, or background tab throttling. Foreground tab + plugged in = full rate. Brave/Edge similar.
