Scroll Wheel Test

Our scroll wheel test is a tool that visualises the precision and reliability of your mouse's scrolling function. Unlike standard scrolling tests that measure speed, this diagnostic tool visually maps every scroll input to detect hardware issues like jitter, reverse scrolling, or missed steps - common problems that disrupt gaming, coding, and browsing.

Your scroll wheel might be malfunctioning due to dust buildup, worn-out internal components, or software issues. Over time, debris can clog the scroll mechanism, causing erratic jumps or unresponsive scrolling. Some mice also suffer from encoder wear, where the physical components degrade or wear down with heavy use. Software glitches, outdated drivers, or incorrect sensitivity settings can also contribute to the problem.

Our scroll wheel test helps you diagnose these issues by visualizing your wheel's behavior in real time. If the test shows inconsistent movement or reverse scrolling, it's likely a hardware problem. If the issue persists and it does not seem to be a hardware issue, also check for driver updates.

The test works by tracking your scroll wheel's movement patterns in real-time as you scroll.

Things to look out for:

• Smooth inputs draw clean, consistent lines
• Glitches can appear as sudden breaks or color shifts
• Sudden reverse scrolling shows as directional anomalies

No installations or accounts needed - just hover and scroll to get instant visual feedback on your mouse wheel's health right here in your browser.

This tool requires a physical scroll wheel.
