What does Sample-and-hold display mean?
A sample-and-hold display keeps an image visible for a substantial part of each refresh interval. The interaction between that persistence and eye movement can influence perceived motion blur, even when individual pixels respond quickly.
Why it matters
This is separate from blur already captured during the camera exposure. Some displays use dark intervals or backlight timing changes to reduce persistence, trading brightness or possible flicker against motion clarity. A higher refresh rating alone does not describe every aspect of the result, and local processing cannot recover source detail that was blurred before encoding.
A practical example
A moving object can look less distinct while you track it with your eyes than when it is paused. Compare comfortable real viewing rather than chasing one motion test pattern, and disable any optional clarity mode that becomes distracting or unpleasant in your room.
