Mouse Tests
- Mouse Button TestClick every button and roll the wheel to confirm each one registers — including the side buttons most tests miss.
- Mouse Double-Click TestSingle-click normally and see whether any press registers twice — the classic sign of a worn mouse switch.
- Mouse Polling Rate TestMove your mouse and see how many times per second it reports to your computer — from 125 Hz office mice to 8000 Hz gaming sensors.
- Mouse DPI AnalyzerSwipe your mouse a known distance and measure its real DPI — not the number printed on the box.
- CPS Test – Clicks per SecondClick as fast as you can and see your clicks per second. The timer starts on your first click.
- eDPI CalculatorCombine your mouse DPI and in-game sensitivity into one comparable number, and see how far you move to turn 360°.
Keyboard Tests
- Keyboard TestPress every key and watch it light up — the fastest way to find a dead, sticky or misbehaving key.
- Typing Speed TestType the words as fast and accurately as you can to measure your words per minute.
- Key Rollover TestHold down as many keys as you can and see how many your keyboard reports at the same time.
- Keyboard Chatter TestTap each key normally and find any switch that types a letter twice from a single press.
Monitor and Display Tests
- Dead Pixel TestFill your screen with solid colours one at a time to spot dead, stuck or hot pixels.
- Monitor Refresh Rate TestFind out how many times per second your screen is really refreshing — and whether your high-refresh monitor is stuck at 60 Hz.
- Monitor Ghosting TestWatch blocks move across three backgrounds and look for trails, blur or bright halos behind them.
- PPI CalculatorEnter a screen's resolution and size to see its pixel density, dot pitch and how close you can sit before pixels become visible.
Audio and Video Tests
- Microphone TestCheck that your microphone works, see how loud it is, and hear exactly how you sound.
- Webcam TestCheck that your camera works and see the resolution and frame rate it actually delivers.
- Speaker TestCheck that both speakers work, are connected the right way round, and can play bass and treble.
- Headphone TestMake sure your headphones play each side correctly, are wired in phase, and cover the full frequency range.
