Ok, here is what I have: Quad-Display Monitors (all working from PC, 2 VGA and 2 DVI) PC Windows Vista Desktop 1 Keyboard 1 Mouse and a Macbook Laptop. I do software development (for PC AND MAC) and need the ability to switch between the PC / MACBOOK on my Quad-Display monitors and use the same keyboard and mouse. Please let me know what I need, I assume some kind of switch but in hours of searching google was not able to find anything to handle this. Also what keyboard would i need to handle MAC and PC functions (prefer wireless). Thanks for any insight!
