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.
