Video Graphics Adapter (VGA):
Note that IBM called VGA 'Video Graphics Array' probably in reference to the
video memory. However, we will use the more popular terminology since it
agrees with the naming conventions of the other PC standards.
Original VGA (31.5 KHz - 640x480)/SVGA (35-37 KHz - 800x600) 15 pin sub D:
1 Red (Analog)
2 Green (Analog)
3 Blue (Analog)
4 Reserved
5 Ground
6 Red Return
7 Green Return
8 Blue Return
9 No Connect
10 Ground
11 (ID0) GND (Color)
12 (ID1) NC (Color)
13 Horizontal Sync
14 Vertical Sync
15 No Connect
Note: Monitor ID Lines ID1, ID0=NC, G for color; G, NC for Mono. ID0 only may be used.
Mono VGA is similar using only the Green Video and Return.
