ApexCheck Hardware Lab

Online mouse test for left, right, middle, side buttons and wheel events, showing whether the browser receives button down/up and scroll input.

• Checks down/up states for primary, secondary, middle and side mouse buttons.
• Includes a live event log for button codes, wheel direction and the latest mouse input.

Touchpad drag test for long-press drag, press movement, drag hold stability and accidental release during text or file dragging.

• Uses separate trails for normal movement and pressed dragging.
• Highlights drag breaks and release state to check tap-to-drag and palm rejection effects.

Double-click test for unwanted repeat clicks, very short click intervals and possible mouse switch bounce.

• Measures the interval between left-click events and flags suspiciously fast repeats.
• Adjustable threshold and click distribution help compare browser evidence with system double-click settings.

Click speed test and CPS tester for measuring total clicks, average CPS, best 1-second CPS and click rhythm over a fixed time.

• Supports short and longer test lengths for burst speed, consistency and fatigue checks.
• Reports average CPS and peak CPS without treating speed scores as mouse hardware diagnostics.

Mouse polling rate test that estimates browser-visible pointermove frequency, event intervals, Hz and movement jitter.

• Shows estimated polling rate, interval samples and jitter for comparing mouse settings.
• Reports browser sampling evidence, not a certified hardware latency measurement.

Mouse scroll wheel test for up/down wheel input, DeltaY, DeltaX, reverse scrolling, skipped steps and unstable scroll segments.

• Records vertical and horizontal wheel events with direction, peaks and accumulated movement.
• Includes a live chart and reverse-event counter for diagnosing jumpy or skipping scroll wheels.

Mouse drag test for held-button movement, drag path continuity, unexpected release and whether the browser receives the final button-up event.

• Records drag paths and break points while the mouse button is held.
• Separates movement, press and release states to narrow down button or tracking issues.

Touchpad test for browser-visible pointer movement, press-drag input, scrolling, pinch gestures and secondary-click signals.

• Separates normal movement from pressed drag paths to expose dropped drags.
• Counts scroll, zoom and secondary-click signals for comparing drivers, browsers and system settings.

Touch screen test for touch points, stylus input, multi-touch, pressure, continuous trails, edge corners and screen coverage grid.

• Shows touch trails, coverage grid and corner areas for finding local dead zones.
• Separates finger, stylus and multi-touch input to reveal dropouts or recognition issues.

Keyboard test for keydown, keyup, modifier keys, function keys, shortcuts and browser-visible multi-key input.

• Highlights pressed keys on a full keyboard layout for quick single-key checks.
• Includes recent event logs and NKRO counts for confirming shortcuts and key release behavior.

Keyboard chatter test for detecting very fast repeated keydown events from the same key, useful for suspected mechanical-key switch bounce.

• Counts suspected chatter per key and shows the fastest repeat interval.
• Can ignore operating-system auto-repeat to reduce false positives from long key presses.

Microphone test for browser permission, input device selection, real-time volume level, peak level and whether audio reaches the current tab.

• Shows live input level and peak changes to confirm microphone signal.
• Lists available input devices to spot wrong defaults or virtual microphones.

Speaker test for browser audio output, left/right channels, stereo playback, test tone frequency and volume control.

• Plays left, right and stereo test tones to check channel direction.
• Adjustable frequency and volume help compare headphones, speakers, monitors and docks.

Webcam test for camera permission, available devices, live preview, negotiated resolution, frame rate and local snapshot status.

• Lists physical and virtual cameras with the resolution and FPS negotiated by the browser.
• Supports local snapshots for checking focus, exposure, color cast and lens blockage.

Monitor and display test for browser-visible resolution, refresh rate, pixel ratio, viewport size and basic screen test patterns.

• Summarizes screen size, viewport size and device pixel ratio for scaling checks.
• Provides basic display patterns and screen information without claiming professional color calibration.

Dead pixel test for checking black pixels, bright pixels, stuck pixels, color spots and uneven areas with full-screen solid colors.

• Uses white, black, red, green, blue and other solid colors to expose pixel defects.
• Includes full-screen mode and keyboard color switching for careful panel inspection.

Test grayscale separation, smooth gradients, shadow detail, highlight detail, RGB transitions, and panel uniformity with full-screen patterns.

• Watch smoothness in gradients, shadow separation, highlight clipping, tint shifts, and whether artifacts stay fixed or move with the browser window.
• Best for color banding, grayscale test, monitor color check, brightness/contrast tuning, and comparing display modes before calibration.

Word counter for characters, non-space characters, English words, Chinese characters, lines and UTF-8 bytes.

• Separates counts with and without spaces for forms, titles and summary limits.
• Supports paste and copy actions for quickly checking text length requirements.

Image metadata and hidden watermark checker for EXIF, GPS, Software fields, PNG text fields, alpha channels and RGB channel clues.

• Shows common metadata and transparency clues before sharing an image.
• Runs RGB channel preview locally in the browser without uploading the original image.

Gamepad test for connection status, buttons, D-pad, stick axes, trigger values, mapping type and browser Gamepad API detection.

• Shows buttons, sticks, triggers and connection data in one controller test view.
• Live updates help confirm whether the browser recognizes the controller and mapping mode.

Stick drift test for left and right stick center offset, X/Y axis drift, maximum offset, return-to-center stability and deadzone behavior.

• Shows idle offset, maximum offset and sustained drift for both analog sticks.
• Adjustable deadzone helps compare drift before and after game deadzone changes.

Gamepad button test for face buttons, D-pad, shoulder buttons, menu buttons, stick clicks, press counts, release events and possible stuck buttons.

• Records down/up state, press count and hold duration for each controller button.
• Highlights missing releases and possible stuck buttons for button-not-working checks.

Controller trigger test for LT/RT or L2/R2 minimum value, maximum value, return-to-zero state, left/right range mismatch and analog mapping.

• Shows each trigger range, peak value and whether it returns cleanly to zero.
• Identifies triggers mapped as digital buttons for LT/RT mapping problems.
