Keyboard Ghosting Test guide

Ghosting happens when several keys are pressed together but the keyboard firmware or matrix wiring fails to report every input. This test is built to expose those failures before you jump into a match or a coding sprint. Press any combination and watch the live counter, current key list, and maximum keys hit so far. If a board claims NKRO, the display should climb as high as you can physically press without missed inputs or phantom extras.

Start with the movement cluster and modifiers because those combos make or break games: WASD plus space, Ctrl, Shift, and number keys for quick binds. Then move to macros or media keys to see if side columns are sharing matrix rows with your main layer. The live ghosting indicator will flag when simultaneous presses are being dropped so you can change keybinds or swap keyboards before a tournament or live stream.

The tester also helps troubleshoot latency spikes from over-aggressive debounce or firmware misconfiguration. Keep visual effects on to confirm each press shows up with a flash, or disable them if you want a distraction-free readout. Because everything runs locally in the browser, you can unplug from the internet and still capture reliable results on Windows, macOS, or Linux without installing drivers or vendor utilities.

After testing, use the clear button to reset counters and start a new run. If you notice drop-offs only after long sessions, repeat the test when the keyboard is warm to uncover intermittent faults. Pair this ghosting test with the single-key tester and the latency page to build a full picture of how your switches, firmware, and USB cable are behaving under pressure.

  • Check diagonals like W+A+Space or Q+E+Shift to mirror common shooter inputs.
  • Use modifier stacks such as Ctrl+Shift+Alt plus a letter to audit shortcut reliability.
  • Try pressing row-based chords (ZXCV or ASDF) to see if your matrix blocks entire lines.
  • Re-test after cleaning keycaps or reseating switches to confirm fixes actually removed ghosting.
