(1) “horizontal resolution” respectively “vertical resolution” determine the horizontal and vertical resolution in pixels.
(2) By default a framerate of 120 is set although that framerate will never be reached. It is just means “as fast as possible”.
(3) The calculation period determines the effective update rate: 1 means every frame’s RGB values will be measured and sent, 4 means only every fourth frame’s RGB values will be measured and the values in between frames will be linearly interpolated. A higher calculation period will make the application run faster and potentially avoid audible or visible steps.
(4) Normalization will force the output range from 0.0-1.0 instead of 0-255. Some applications may require a normalized output rather than a raw one.
