Motion diagnostic

Motion Blur Test

Compare moving text and fine bars to visually inspect motion clarity.

Start and follow the moving text and bars with your eyes. Compare their readability with the stationary reference and with the paused pattern.

Ready — motion is paused

Stationary reference: READ 4826

Motion wraps at the edge. Compare the center of each pass; wrapping is not a panel trail.

How to use this test

  1. Compare the stationary READ 4826 reference with the paused moving text.
  2. Start motion and follow the text and fine bars with your eyes at the same viewing distance.
  3. Compare another speed or direction, then Pause to compare readability again. Reset returns to the default paused view.

What to look for

Try to read READ 4826 and distinguish the moving fine bars while following them with your eyes. Compare the stationary reference and paused pattern at the same viewing distance. This focuses on readability and perceived moving-image clarity; use Ghosting Test to concentrate on colored trails and edge halos instead.

Know the limitations

Perceived blur depends on eye tracking, refresh rate, display persistence, pixel transitions, browser frame delivery, and speed. Font rendering, scaling, and camera shutter/capture technique can change the observation. The page does not calculate blur duration, MPRT, response time, or a clarity score. CSS pixels per second are requested browser motion, not measured physical panel speed.

If moving text becomes hard to read

Try a lower selected speed and compare the stationary reference before changing display settings. Scaling, eye tracking, panel behavior, and browser frame delivery affect clarity. A readability difference is an observation, not a blur-duration score. For edge halos or trails, use the block pattern instead.

Common questions

Why can moving text look softer than stationary text?

The displayed image and your eyes interact during motion. Display persistence, refresh cadence, pixel transitions, and eye tracking can all contribute. Comparing at several speeds helps describe the effect without measuring a hardware specification.

Is this the same as the Ghosting Test?

The controls share an animation engine, but the tasks differ. This pattern checks moving text readability and fine-detail separation; Ghosting uses blocks to inspect trails and overshoot around edges.
