By default the Benq XL2420Z runs on 120 Hz mode. This means that the minimum time that a stimulus is shown is 8.3 ms. The monitor menu, reachable with the touch buttons on the right side of the monitor has a ''blur reduction'' setting. This changes the backlighting of the LCD screen in such a way that it is lighted only a quarter of the time. A stimulus present on the screen for one frame will now be visible for only 2ms.

Additionally the setting is useful when not only the onset (moment of appearing) but the moment the object is perceived is important. Do note that the latency of the onset does not change.
