I am looking at the GA-E7AUM-DS2H board to build an HTPC and whilst I appreciate that I can't have both the DVI and HDMI output at the same time can I have both connected but decide which to output to..?

I would like the HDMI connected to my TV but when I need to view the HTPC from my PC's alternative DVI input I would like to switch to that without needing to do anything other than make sure the TV is off.

Is that possible or is something more elaborate needed to output from one to the other...?
