try hooking up a monitor to the laptop and see if the dual display card works with/ the monitor first.....that should be an issue of going into windows and telling your system you WANT to use dual display feature. Once you get that to work, then you'll be able to hook the "modulator" up, which I think will convert the signal so that you can plug RCA into TV. Personally I bought a converter that comes out of USB on laptop and i can send signal to multiple destinations at same time,,,,,,old style TV and new style projector at same time.
Good Luck,
Randy
