This is a very basic diagram of what I am working on trying to understand here. I belive there are a few connections that must be maintained even when switched over. Is it absolutely needed, no. You can unplug a monitor cable on a working PC. However in the interest of trying not to surge or shock the system. I would like to keep some of the lines connected ( per your suggestion ). I am looking at the pin out as follows:
1  red
2  green
3  blue
4  monitor ID bit 2
5  digital Ground
6  red analog ground
7  green analog ground
8  blue analog ground
9  no connection
10 synch return (ground)
11 monitor ID bit 0
12 monitor ID bit 1
13 horizontal sync
14 vertical synch
15 no connection
I don't think it needs to be any more complicated than this. At least right now. I looking for a multi pole switch or IC chip that will work like this. If you know an IC chip number that does let me know. If I can get this built and tested I will let you know. Sorry for the delays.
