[comp.sys.ibm.pc] How to adapt PGA monitor to VGA card ?

wilker@hopf.math.purdue.edu (Clarence Wilkerson) (06/01/90)

I recall having seen used PGA monitors being advertised for use with
VGA cards. Looking at the pinouts, one obvious problem is the the 
PGA monitor takes a combined horizontal and vertical sync signal, while
the VGA adaptor puts out separate syncs. The frequencies are slightly
different by a percent or so, but I assume one can adjust that slightly.
Any points to the rest of the adaptation ( especially the sync problem?).
Thanks, Clarence Wilkerson
