• Total pixels (RGBHV/RGBS/RGsB and progressive/HDTV component
only) — The total number of pixels per line, including the blanking on both
sides of the input active area (active, horizontal sync width, back porch, and
front porch).
The total number of lines per frame, including the blanking above and below
the active area, is determined by the input signal and is not user adjustable.
Use these controls to match the input video signal and to frame the active area.
The active pixels and total pixels adjustments are interactive. Setting one of
these variables may require adjusting the other.
