I am interested in buying a GTX 570 graphics card, what I want is to have dual monitors connected as my display. But to also have a TV just connected to the mini HDMI port but then used as an external output, like the windows projector function. This would then turn the two monitors off so that I can watch movies. Would this work on the Nvidia GTX 570? Was just thinking of this as a way to get around the maximum of 2 displays.
