SX0 and SY0 are integer numbers. Showplay uses SX0 and SY0 as the horizontal and vertical center pixel position for all visual stimuli that are to be centered in the display.

The default value for SX0 is 1/2 the paradigm display screen width. The default value for SX0 is 1/2 the screen height.

For physical screen center coordinates see Dx1/Dy1. For dual screen displays, see Dx2/Dy2 for the center coordinates of the secondary display screen.
