What is Button ghosting? (Explained by an Expert)

Button ghosting occurs when a controller registers unintended inputs due to multiple buttons being pressed simultaneously. High-quality fightsticks typically have built-in mechanisms to prevent button ghosting, ensuring accurate inputs during gameplay.

It happens when the controller or keyboard incorrectly registers an additional button press (a “ghost” press) that the user did not intend to make. This unintended input can lead to undesired actions in a game or application, negatively impacting the user experience and performance.

Ghosting is often a result of limitations in the underlying matrix circuitry design of keyboards and controllers.

When multiple buttons share the same row or column in the matrix, pressing several buttons at once can cause electrical signals to cross paths, leading the controller or keyboard to register a ghost press.

To mitigate button ghosting, manufacturers implement various solutions:

  1. Anti-Ghosting: Anti-ghosting technology is designed to prevent ghosting by isolating button circuits or adding diodes to the matrix to prevent signal interference. This allows for simultaneous button presses without generating ghost inputs.
  2. N-Key Rollover (NKRO): NKRO is a feature that allows a device to register multiple key presses accurately and simultaneously without dropping inputs or causing ghosting. This is particularly important for gaming keyboards and controllers, where users often need to press multiple buttons at once.
  3. Higher Quality Components: Premium keyboards and controllers tend to have better-designed circuitry and more reliable components, which can help reduce the chances of button ghosting.

It’s essential to consider button ghosting when choosing a gaming keyboard or controller, as it can significantly impact your gaming experience and performance. Look for devices with anti-ghosting technology or NKRO to ensure the most accurate input registration during intense gaming sessions.
