Have DEC mod PCW11-A2 computer (433Workstation) with DEC PCHBV-BC monitor. All looks good in DOS but Windows comes up with the "window" in the center of the screen. Have tried normal VGA & VGA (3,0 ..) drivers. No doc for monitor switch on back of computer. Using position #7.
DEC -Tec tried, but could not help. Can you?
