3.11 VGA

COM Express provides analog display signals that send color information to a VGA

monitor. There are three signals: red, green, and blue. Analog levels between 0

(completely dark) and 0.7 V (maximum brightness) on these control lines tell the monitor

what intensities of these three primary colors to combine to make the color of a dot (or

pixel

) on the monitor’s screen.
