How it works
Your browser draws a new frame each time the screen refreshes. By counting frames per second, the tool estimates your display’s refresh rate and rounds to the nearest standard value (60, 90, 120, 144, 165, 240 Hz…).
Showing 60 Hz on a 144 Hz laptop?
- Windows may be set to 60 Hz: Settings → System → Display → Advanced display → Choose a refresh rate.
- Battery saver or “dynamic refresh rate” can drop to 60 Hz on battery – plug in the charger.
- If you have an external monitor, the browser follows the screen it’s on.
- Close heavy tabs; a busy browser can drop frames.
Does refresh rate matter?
For office work and study, 60 Hz is fine. For gaming, 120–144 Hz makes motion visibly smoother and can help aiming. Many gaming laptops (ASUS TUF, HP Victus, Lenovo LOQ/Legion, Acer Nitro) have 120–165 Hz screens – a good reason to check before buying a used gaming laptop.
Frequently asked questions
Is the result exact?
It is a close estimate based on browser frames; Windows display settings show the exact configured value.
Can I increase my laptop's refresh rate?
Only up to what the panel supports. Check the options in Windows advanced display settings.
