Test guides

Choose the right hardware test

Diagnose common peripheral problems without installing software. Each guide explains what the test checks, which symptoms it can reveal and how to read the result before you replace or repair a device.

Pointing devices

Online Mouse Test — Buttons, Scroll and Polling Rate

Check left, right, middle and extra mouse buttons, then verify vertical and horizontal wheel input. The live event display helps identify missed clicks, accidental double-clicks, unstable dragging and inconsistent USB polling rate.

  • Button response
  • Double-click detection
  • Scroll wheel
  • Drag accuracy
  • Polling rate

Input devices

Online Keyboard Test — Ghosting, NKRO and Stuck Keys

Press individual keys or combinations to confirm that every input is detected. The visual keyboard highlights active keys and makes it easier to find chattering switches, stuck keys, layout problems, ghosting and N-key rollover limitations.

  • Full key map
  • Anti-ghosting
  • N-key rollover
  • Lock indicators
  • Stuck keys

Display diagnostics

Monitor Test — Dead Pixels, Backlight, Gamma and Motion

Use full-screen solid colors to locate dead or stuck pixels, and dark patterns to inspect backlight bleed. Gradient, gamma, contrast, sharpness and motion screens help reveal color banding, crushed detail, scaling artifacts and slow pixel response.

  • Dead pixels
  • Backlight bleed
  • Color gradients
  • Gamma & contrast
  • Motion response

Microphone Test — Live Level, Waveform and Recording

Allow microphone access to inspect the live input level and waveform, then make a short local recording and play it back. This can expose low volume, clipping, background noise, dropouts, channel problems or the wrong selected input device.

  • Live input meter
  • Waveform
  • Local recording
  • Playback check
  • Device selection

Video input

Webcam Test — Resolution, FPS and Image Quality

Preview your camera feed and confirm the detected resolution, frame rate and available capabilities. Use the live picture to check focus, exposure, color, low-light performance, freezing, dropped frames and whether the correct webcam is active.

  • Live preview
  • Resolution
  • Frame rate
  • Image quality
  • Camera selection

Controllers

Gamepad and Racing Wheel Test — Buttons, Axes and Drift

Connect a controller or racing wheel and inspect every button, trigger, stick, pedal and steering axis in real time. The test helps detect analog drift, incorrect dead zones, unresponsive inputs, limited travel and supported vibration feedback.

  • Buttons & triggers
  • Stick drift
  • Axes & dead zones
  • Racing wheels
  • Vibration

Audio output

Online Tone Generator — Frequency, Waveforms and Sweep

Generate a sine, square, triangle or sawtooth tone, white or pink noise, or a frequency sweep through speakers or headphones. Check left and right channels with the A/B switch, polarity with phase invert, audible range, resonances, rattling and intermittent output. Start at a low volume and increase it carefully.

  • Frequency control
  • Four waveforms + noise
  • Tone sweep
  • Left/right A/B
  • Phase invert

Logitech & Razer Configurator — DPI, Buttons, Lighting and Pairing

Change the settings of Logitech mice, keyboards, headsets and receivers directly in Chrome or Edge: DPI levels and polling rate, button mapping and lighting in onboard profiles, SmartShift and scroll direction, F-keys and game mode, sidetone and equalizer, Easy-Switch, and pairing or unpairing on Unifying, Logi Bolt and LIGHTSPEED receivers. Razer mice get DPI, DPI stages, polling rate up to 8000 Hz, sleep timer and low-battery mode — all without G HUB, Options+ or Synapse.

  • DPI & polling rate
  • Onboard profiles
  • Button mapping
  • Lighting
  • Pairing

Common questions

Hardware testing FAQ

Quick answers about compatibility, privacy and what browser-based diagnostics can tell you.

Are the BeogradPC hardware tests free?

Yes. Every mouse, keyboard, monitor, microphone, camera, gamepad and audio test is free to use in a supported web browser.

Do I need to install software or create an account?

No. The tests run directly in the browser and do not require an installation, extension or user account.

Are microphone and camera recordings uploaded?

No. Camera and microphone data are processed locally in the browser. The test pages do not upload your recordings.

Which browsers work with these online hardware tests?

Current versions of Chrome, Edge, Firefox, Safari, Opera and Brave support most tests. Hardware access can vary by browser, operating system and device.

Why does the browser ask for camera or microphone permission?

Browsers require explicit permission before a website can access a camera or microphone. The device is used only while the test is running, but your browser may remember the permission for this site; you can revoke it at any time in the browser's site settings.

Can I run the tests on a phone or tablet?

Yes. Camera, microphone, display and audio checks work on many phones and tablets. Keyboard and gamepad results depend on connected hardware and browser support.

How accurate are browser-based polling rate and frame rate measurements?

They are useful diagnostic measurements, but results can also reflect browser load, operating-system scheduling, power settings and other active applications.

Privacy: All processing happens locally in your browser. Test data is never uploaded. This page stores only the theme preference, under localStorage key bpc:theme, which is shared by all tests in the suite. Each test keeps its own settings under its own prefix (listed in that test's Privacy note).
