Factors affecting Latency

When you’re testing keyboard latency, several key factors can influence your results. You’ll need to consider the keyboard’s polling rate, scan rate, response time, and connection type. Each of these elements plays a crucial role in determining how quickly your keystrokes are registered.

Keyboard Polling Rate

How does the keyboard polling rate impact the latency you experience while typing or gaming? The polling rate refers to how often your keyboard reports its status to your computer. A higher polling rate means the keyboard is communicating with the computer more frequently, which can reduce the time it takes for your keystrokes to be registered. This is crucial for both typists seeking a responsive feel and gamers requiring split-second precision.

Here’s how different polling rates can affect your experience:

• 125 Hz (8 ms): This is the most common polling rate for standard keyboards. It’s sufficient for everyday typing but might feel slightly laggy for fast-paced gaming.
• 250 Hz (4 ms): This offers a noticeable improvement in response time and can enhance your overall typing experience.
• 500 Hz (2 ms): This rate is typically found in gaming keyboards and provides a very responsive feel, suitable for most gaming scenarios.
• 1000 Hz (1 ms): The highest standard rate, delivering near-instantaneous response times, ideal for competitive gaming.
• Variable Rates: Some advanced keyboards allow you to adjust polling rates based on your needs, providing flexibility between everyday use and high-performance gaming.

Keyboard Scan Rate

Beyond the polling rate, the keyboard scan rate also plays a significant role in determining latency, as it dictates how quickly the keyboard’s internal hardware scans for key presses. Essentially, the scan rate measures how often the keyboard checks each key to see if it’s been pressed. A higher scan rate means the keyboard can detect key presses more frequently, reducing the time it takes for your input to be registered.

You might wonder how this works in practice. When you press a key, the keyboard’s microcontroller scans the key matrix. If the scan rate is low, there’s a delay before the microcontroller detects the key press. On the other hand, a high scan rate allows the keyboard to detect and process key presses almost instantaneously.

It’s essential to understand that both the polling rate and the scan rate contribute to overall latency. While the polling rate is how often the keyboard sends data to your computer, the scan rate is how quickly it detects key presses internally. If you’re looking to minimize latency, you’ll want a keyboard with both a high polling rate and a high scan rate. This ensures that from the moment you press a key to the moment your computer registers it, the process is as fast as possible.

Keyboard Response Time
