- Covid makes a cable which will do this. So do many other cable manufacturers -
- so get a catalog.
-
- The pinout of the VGA connector is:
-
- 1 - Red
- 2 - Green
- 3 - Blue
- 4 - Reserved
- 5 - Self Test
- 6 - Red Ground
- 7 - Green Ground
- 8 - Blue Ground
- 9 - Key ( no pin )
- 10 - Digital Ground
- 11 - Display ID 1
- 12 - Display ID 2
- 13 - H sync
- 14 - V sync
- 15 - Reserved
-
- It is often possible to hook up Red,Green,Blue, H, and V to the monitor
- and get it working. Sometimes, though the monitors will not run as slow
- as VGA. One problem that crops up has to do with pins 11&12. These may
- have to be tied to ground to get the card to light up. If you are an
- experienced cable-hacker, you can probably get this to work pretty easily.
