im going to be getting an USB I/O card so i can cantrol / monitor variouse things suck as lights, SW controls switches etc.

one idea i came up with is taking the lights on cable thats in the sterio wiring harnes can connection it up to the I/O Controller, then have that launch one of the gama control progs to dim to screen when the lights go on and go back to normal when they are off.

has anyone tried this?
