FPGA, and the inputs to those ports determine the corresponding color signal voltage delivered to the
VGA connector. The sync signals must be produced by a controller residing in the FPGA.
VGA signal timings are specified,

following VGA system timing information
is provided as an example of how a
VGA monitor might be driven in 640 by
480 mode. For more precise
information, or for information on higher
VGA frequencies, refer to
documentation available at the VESA
