About RefreshRateTest
RefreshRateTest is an independent browser-based utility developed to provide fast, privacy-respecting display checks and educational references for monitor owners, gamers, and software developers.
Why This Site Exists
Millions of computer users purchase 120Hz, 144Hz, 240Hz, or 360Hz monitors, only to have them quietly run at 60Hz. This commonly happens because an operating system defaults newly connected displays to 60Hz, a legacy cable lacks sufficient bandwidth, or a laptop dock limits the refresh cadence.
RefreshRateTest was created to solve this practical problem: give users an instant, software-free way to verify what presentation cadence their browser is receiving, without installing executable files, drivers, or granting invasive system permissions.
Who Develops & Maintains the Site
RefreshRateTest is an independent web development project created and maintained by a display technology enthusiast. We do not operate a commercial testing laboratory, nor do we employ an institutional research team.
Our guides and technical articles are authored under the RefreshRateTest Editorial byline. Every recommendation, cable bandwidth table, and diagnostic workflow is grounded in published technical documentation from standards bodies—including the Video Electronics Standards Association (VESA), the HDMI Forum, browser specifications (W3C/WHATWG), and GPU driver documentation from NVIDIA, AMD, and Microsoft.
What Our Tools Measure — And Their Limits
We believe in honest technical communication rather than exaggerated claims:
What the Tool Measures
Our tools measure browser rendering and frame presentation cadence using requestAnimationFrame and performance.now(). This timing demonstrates how frequently your browser updates on-screen visuals.
What It Cannot Replace
A web application cannot replace hardware oscilloscopes, optical photodiode probes, or colorimeters. Browser estimates can be influenced by OS compositor throttling, GPU workload, multi-monitor pacing, and power-saving settings.

Core Values & Editorial Standards
100% Client-Side Privacy
All tests run locally in your browser sandbox. We never record your screen, log hardware serial numbers, or require account signups.
Zero Software Downloads
You never need to install third-party executables or risk workstation security. Everything works seamlessly via standard HTML5 Canvas and WebGL APIs.
Commitment to Corrections
Display specifications evolve constantly. If you spot an inaccurate specification, outdated cable timing, or broken tool behavior, we review and update pages promptly. Visit our Contact & Corrections page.
