About Monitor Refresh Rate Test
This monitor refresh rate test displays moving patterns to help you verify your display's actual refresh rate and detect frame skipping. Confirm your monitor runs at 60, 144, or 240 Hz as expected. Runs in your browser — no downloads or uploads required.
Frequently Asked Questions
How do I know if my monitor is running at its full refresh rate?
Run this test in full screen. The moving blocks should appear smooth and evenly spaced. If blocks overlap or stutter, your monitor may not be running at its advertised refresh rate — check your display settings.
What causes frame skipping?
Frame skipping happens when the GPU cannot render frames fast enough or the display cable bandwidth is insufficient. Use DisplayPort for high refresh rates and ensure your GPU drivers are up to date.
Does 144 Hz make a noticeable difference over 60 Hz?
Yes. 144 Hz is noticeably smoother than 60 Hz for gaming, especially in fast-paced FPS games. The jump from 60 to 144 Hz is more impactful than 144 to 240 Hz.
