When I installed a 105 in my HT setup for audio from a DirecTV HD-DVR, I removed a DVDO iScan Duo and ran HDMI-1 directly to the projector. The projected picture looked about the same. Recently I decided to try tweaking the picture with the Oppo menu controls. The result made the picture pop with our Sony VPL-50 that's on its third or fourth lamp. The screen is 100" 16 X 9 of material claimed to be equivalent to Stewart's 130. The resulting picture is comparable to that of our Sony 46 XBR8, i.e., amazing.
