Monitor Refresh Rate Test (Hz) Step By Step

Monitor Refresh Rate Test (Hz) takes three short steps: open the page, start measuring, then read the Hz estimate.


Step 1 - open the tool

Go to Monitor Refresh Rate Test (Hz). No install and no login.


Step 2 - start measuring

Click Start measuring. Keep this tab in the foreground so requestAnimationFrame is not throttled.


Step 3 - read Hz and stop

Watch the large Hz reading settle as samples accumulate. Click Stop to freeze it, or Reset to clear. Nothing left the tab.

Why trust these tools

  • Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
  • No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
  • Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
  • Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
  • Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
