Depends on how
you define "VGA", as there are many possible definitions
of "VGA". (PeeCee video mode switching madness...)
Connect the RGB signals from the VAXstation to the RGB pins of a VGA
connector, plug it into a display and see what it makes out of it. Many
VGA displays can sync to sync on green signals just fine. It will not
brake anything if not. The H- / V-fequencies of the VAX video signals
are somewhere around SVGA / XGA. (1024 x 864 @ 66 Hz or the like. There
may be a 1280 x 1024 mode also, selectable by a DIP switch on the SPX
board.)
