I understand the frustration that comes with keyboard ghosting. It’s a term that refers to the occurrence of a keyboard not registering certain keystrokes when multiple keys are pressed simultaneously. This can be a significant issue for gamers, typists, and anyone who relies on their keyboard for work or play.

In this article, I’ll discuss what keyboard ghosting is, what causes it, and how you can fix it. So, let’s dive in!


What Causes Keyboard Ghosting?

To understand keyboard ghosting, we first need to know how keyboards work. A keyboard uses a matrix of circuits to transmit signals to the computer when a key is pressed. When you press a key, it completes a circuit that sends a signal to the computer, which then registers the keystroke.

However, most keyboards have a limitation on the number of keys that can be pressed simultaneously. This limitation is known as rollover. Key rollover is the maximum number of keys that a keyboard can register at once.

When you press too many keys simultaneously, the keyboard may not be able to register all the keystrokes. This results in ghosting, where some keys are not registered, making it seem like they’re “ghosting” or not registering at all.

How to Fix Keyboard Ghosting

Now that we know what causes keyboard ghosting let’s discuss how to fix it. Here are a few solutions you can try:

1. Use a Keyboard with N-Key Rollover

N-key rollover is a feature found in some keyboards that allows for an unlimited number of keys to be pressed simultaneously, eliminating the issue of ghosting. If you’re experiencing keyboard ghosting frequently, it may be time to invest in a keyboard with N-key rollover.

2. Disable Filter Keys in Windows

Filter Keys is a feature in Windows that ignores brief or repeated keystrokes, which can cause ghosting. Disabling this feature can help eliminate ghosting. To disable Filter Keys, go to Settings > Ease of Access > Keyboard > Filter Keys and toggle the switch to off.

3. Clean Your Keyboard

Dirt, dust, and debris can accumulate under your keyboard’s keys, causing some keys to stick, which can lead to ghosting. Cleaning your keyboard regularly can help eliminate this issue. Use a can of compressed air or a soft-bristled brush to remove any debris under the keys.

4. Check for Stuck Keys

Stuck keys can also cause ghosting. If you’re experiencing ghosting, check for any keys that are stuck or not functioning correctly. Gently press each key to see if any are stuck, and if you find one, try to gently pry it up with a small tool like a toothpick.


In conclusion, keyboard ghosting is a common issue that can cause frustration for anyone who relies on their keyboard. However, there are several solutions you can try to fix it, including investing in a keyboard with N-key rollover, disabling Filter Keys in Windows, cleaning your keyboard, and checking for stuck keys.

As someone who loves keyboards, I understand the importance of having a reliable keyboard that doesn’t cause ghosting. By following the solutions provided in this article, you can eliminate ghosting and enjoy a seamless typing or gaming experience.
