Looking into hooking my 3100 up with my Dell 2408, which I can see vid not being an issue, sound on the other hand seems to be, or I am missing the obvious. I was also looking into upgrading to an HD pvr for this, but would like to know if this would be possible before making the switch. Obviously the monitor has no speakers, and I have extra computer speakers w/sub lying around, but can I hook the 3100 reciever or a HD reciever with it. Thanks for any info..
