MBR (Motion Blur Reduction) Pro helps reduce motion blur by lowering display persistence time during fast-moving gameplay. By briefly controlling the backlight between frames, it helps reduce the continuous image hold effect. This allows fast-moving objects to appear clearer and sharper with less motion blur, improving target tracking, motion precision, and reaction speed during competitive esports play.
