DisplaysHow to Check Your Monitor's Refresh Rate (and Change It)
Where to see your Hz on Windows and Mac, how to change it, and the cable and setting mistakes that keep a 144 Hz screen at 60.
SpecsHow to Check Your PC Specs (Windows, Mac and Chromebook)
The fastest way to find your processor, RAM, graphics card and storage on Windows, Mac or a Chromebook.
GamingWhat Is a Good Reaction Time? (And What Changes It)
Lab averages, typical online scores, and the screen and mouse delays that quietly add milliseconds.
Quick checks before it matters
A mic that's muted at the start of an interview. A webcam that shows a black box on a client call. A new monitor with a stuck pixel you notice a day after the return window closes. Gadgetior is a set of free tests that catch those problems early, in a few seconds, without installing anything.
Every test runs inside your browser. When a test needs your microphone or camera, the browser asks you first, and the audio and video stay on your device. We don't record it, store it or send it anywhere.
Each page also explains what the results mean and walks through the fixes that solve most problems, with links to the official help pages from Microsoft, Apple and the web standards docs.
Frequently asked questions
Are the Gadgetior tests free?
Yes. Every test is free, with no account, no limits and nothing to download.
Do you record my microphone or camera?
No. The mic and webcam tests run entirely in your browser. Audio and video are never uploaded or stored.
Do the tests work on phones?
Most of them do, including the mic, camera, speaker, dead pixel, refresh rate and device specs tests. The keyboard and mouse tests are made for computers.
