WASD ghosting test
Gaming keyboards should reliably detect movement keys with Shift, Ctrl, and Space for common in-game actions.
How keyboard ghosting happens
Ghosting can happen when a keyboard matrix cannot uniquely detect certain simultaneous key combinations.
Ghosting vs rollover
Ghosting is about missing or incorrect keys in a combination. Rollover is about how many simultaneous keys can be detected.
What to do if keys are missing
Retest the combination, try another browser, and compare with the rollover page before assuming the keyboard is defective.
Help
What does keyboard ghosting mean?
Keyboard ghosting means some key combinations are not detected correctly when multiple keys are held together.
Is ghosting the same as rollover?
No. Ghosting is a combination detection issue, while rollover describes simultaneous key detection capacity.
