DVI Connections


I am probably missing something very basic here but it is escaping me at the moment. I currently have a Denon 5900 that I have connected directly to the TV with the DVi connection. I am ready to get the HD setup now from direct TV, but it is my understanding that the HD signal needs that input on the TV as well. How do I connect both components to the TV? Again, maybe I am just spacing out on this one, but I figured I would ask.

Thanks

Thanks. I figured it was a simple answer. There seems to be a number of switches available. Does anybody have a recommendation on which one to look at. I am only looking to connect 2 sources to the monitor at this time.
Thanks
I had the same problem and had to buy a DVI switcher. Gefen makes a decent one, here's a link:
