What Is Keyboard Ghosting?

Keyboard Ghosting is a term used when a keypress does not register on your PC. This usually happens when you press multiple keys at the same time. To test this among yourself, you can press multiple keys on your keyboard to see how many of them are getting registered. Generally, keyboards come with 6KRO, that is six key rollover. 

So if you press one key additionally, no response will be registered. No character will be seen on the screen as you have crossed the maximum permissible limit for a 6KRO keyboard. This lost input is called Ghosting. When you’re typing, it does not become a big issue. But if you’re gaming, you might need to press multiple keys simultaneously. 

There are multiple reasons behind this lost input. It can happen because of hardware incompatibility or because the software simply does not support multiple keypresses. But how to overcome this issue? That’s when anti ghosting keys come into the picture.

What Is Anti Ghosting Keys Technology?

The anti-ghosting feature simply ensures that all key presses are sent without error and registered in the order they’re pressed. Keyboards with anti-ghosting technology will register all keys pressed at the same time without “ghosting” any input. These keyboards have extra wires that ensure that each key creates unique signals so that you don’t experience ghosting.

How To Fix The Problem Of Ghosting?

For most simple anti-ghosting keyboards they will have a different arrangement of wires to resolve the issue for the most common combination of keystrokes. These keyboards have a separate diode that will allow every key to register no matter what the combination is. 

Remapping Your Keyboard

The only real workaround is to remap your keyboard so that the key combination you want to use is one that your keyboard is able to register. Remapping your keyboard means adding new actions or functionalities to existing keys.

Advantages Of Anti-Ghosting Keyboard
