I've got my TV hooked up to my PC and sometimes download movies to watch on the TV. I have an Nvidia GE force 7950 GT graphics card with a DVI to HDMI cable running straight to my TV. Changing from one monitor to two is as easy as going into the Nvidia menu and selecting the configuration I want (monitor 1 only, clone, or two monitors receiving two signals). It's not that hard. I also have to click on my Turtle Beach Montego sound card icon and change my sound from the PC speakers over to my surround sound when I want to watch a downloaded movie (several more clicks of the mouse). For that card, I'm using an optical cable running to my receiver.
