A monitor retraining device includes a handheld housing, a controller disposed within the housing, and a connector connected to the controller and connectable directly to a monitor having a screen. The controller has a first state wherein the controller provides an output signal to the connector to cause the monitor to display a white image over the entire screen for a first time period, and a second state wherein the controller provides no output signal to the connector to cause the monitor to display a black image over the entire screen for a second time period, the controller automatically alternating between the first and second states without feedback as to the white image or the black image displayed.
