I have been running my Xbox 360 to my Dynex DX-LCD42HD-09 at 1080p just fine for a while now, and wanted better sound so I bought the Samsung HT-AS720ST
I have the 360 going to the receiver via HDMI, and then out to my tv also using HDMI. I get a picture at 720p and 1080i, but at 1080p my tv sees the signal, but just displays a gray screen.
Any ideas?
