Erreurs courantes
- Confusing logical resolution with native resolution — always check the Device Pixel Ratio to understand the relationship between CSS pixels and physical pixels.
- Reading stats while the browser is not maximized — for accurate screen resolution numbers, ensure the browser is in fullscreen or compare with your OS display settings.
- Assuming the refresh rate estimate is exact — the rAF-based measurement is a good approximation but may vary slightly under CPU load.
