- Hi,
-
- I was wondering if someone knows if it is possible to have two video
- cards fitted in an IBM PC and to either use them both at the same time (same
- output) or to selectively (by software) choose one or the other. In
- particular, I'd like to be able to have a (S)VGA and an EGA/CGA card together.
-
- The reason I ask is that I'd like to try and use an overhead projector
- panel with my PC, but the panel only accepts EGA or CGA from a nine pin
- output.
-
- Or do you think a VGA card should be able to detect what sort of device
- is attached and so output in CGA/EGA/VGA as appropriate?
-
- Thanks for the help,
-
