I have a lenovo y580 laptop with a Geforce GTX 660M Graphics card. My BIOS says that the graphics mode is "Switchable Graphics," however the Geforce card is not in use. I want to be able to hook up a 3rd monitor to my laptop (2 external + the one built in), but I have to have the Geforce card in use to do that. Does anyone know how to get it working?
