This test is for Motion Blur Reduction modes in displays and gaming monitors including ULMB / Blur Reduction / DyAc / MOTION240 / LightBoost / etc.

This test will reveal double-image effects caused by strobe crosstalk. Blur Reduction modes use a strobe backlight or scanning backlight to reduce motion blur. Some brands have utilities to allow calibration of Blur Reduction, such as Strobe Utility for BenQ/Zowie monitors.

Run this test in full screen mode. Adjusting Strobe Phase (Area) will shift the location of double-image effects. Adjust for clearest image (least double-image effect). For an advanced technical explanation of strobe crosstalk, see Strobe Crosstalk FAQ.
