How to Estimate Screen Refresh Rate Online
Web animation timing can estimate how often a browser draws frames, but it cannot certify the hardware panel.
Before you begin
Start with reversible settings checks. Keep your device supported and powered safely. Do not force connectors, open sealed batteries or try high-voltage repair steps.
Step-by-step testing instructions
- 01
Use the device in its normal mode
Set the intended refresh rate in display settings.
- 02
Close unnecessary background apps
Heavy applications and energy-saving modes can distort frame timing.
- 03
Keep the tab visible
Hidden tabs throttle requestAnimationFrame in many browsers.
- 04
Run repeated estimates
Compare multiple runs rather than relying on a single result.
- 05
Check system display information
Compare the estimate with OS panel settings or manufacturer documentation.
Check the result.
Treat browser frame cadence as a useful clue, not an exact physical panel measurement.

If the same problem occurs in multiple compatible applications or devices after safe checks, follow the manufacturer's exact support instructions or ask a qualified repair professional. A browser test cannot prove every hardware component is healthy.
