# Hardware Test Pro > Free browser-based hardware checks for displays, mice, keyboards, audio devices, controllers, webcams, and system performance. No account or installation required. ## Browser-Test Scope HardwareTest.org reports browser-accessible signals and visual checks. Results may be affected by browser support, operating-system settings, device permissions, connected hardware, power settings, and background load. Browser tools do not replace manufacturer utilities, native diagnostics, calibrated instruments, or professional medical evaluation. ## Core Tools - [Dead Pixel Test](https://hardwaretest.org/dead-pixel-test/): Inspect a display with fullscreen color patterns. - [Keyboard Test](https://hardwaretest.org/keyboard-test/): Check browser-visible key registration and common combinations. - [Mouse Test](https://hardwaretest.org/mouse-test/): Check standard button and wheel events delivered to the browser. - [Mouse Polling Rate Test](https://hardwaretest.org/mouse-polling-rate-test/): Estimate browser-visible pointer event Hz and stability. - [Refresh Rate Test](https://hardwaretest.org/refresh-rate-test/): Estimate the active refresh-rate tier from browser animation-frame timing. - [Controller Test](https://hardwaretest.org/controller-test/): Inspect Gamepad API buttons, axes, triggers, and stick-drift symptoms where supported. - [Sound Test](https://hardwaretest.org/sound-test/): Play channel, tone, and noise references and optionally view local microphone levels. - [Webcam Test](https://hardwaretest.org/webcam-test/): Preview a permission-based browser camera stream and inspect exposed stream settings. - [HDR Test](https://hardwaretest.org/hdr-test/): View HDR setup patterns within browser-rendering limits; this does not measure nits or certify HDR performance. - [RAM Checker](https://hardwaretest.org/ram-checker/): Inspect privacy-limited browser memory values and a small allocation timing check. - [All Tools](https://hardwaretest.org/tools/): Browse the complete tool directory. ## Selected Guides - [Browser Mouse Polling Rate Explained](https://hardwaretest.org/blog/mouse-polling-rate-browser-test-explained/) - [Dead Pixels vs Stuck Pixels](https://hardwaretest.org/blog/dead-vs-stuck-pixels/) - [IPS Glow vs Backlight Bleed](https://hardwaretest.org/blog/ips-glow-vs-backlight-bleed/) - [Stuck Pixel Fixer Guide](https://hardwaretest.org/blog/stuck-pixel-fixer-repair-guide/) - [Controller Stick Drift Guide](https://hardwaretest.org/blog/how-to-detect-and-fix-controller-stick-drift/) - [Audio Balance Guide](https://hardwaretest.org/blog/audio-balance-test-fix-uneven-sound/) ## Privacy Summary Raw inputs such as keystrokes, microphone audio, camera video, and controller events stay in the browser.
