Ultimate setup for AE100 :
radeon based htpc
hipix card for OTA hd.
Cygnus(?) I would like to check this out w/panamorph
Xander, IMO the important thing is the ratio of width to seating distance, not the actuall screen width. I think people are starting to notice that they can push the actual AE screen width much further than it's DLP counterparts, even when the DLPs have a higher rated lumens.
I created a 150" image with the AE to check out some theories about sub pixel elements and I was very impressed with how well the AE picture looked. Of course you would have to sit at 300" to avoid screendoor, but I think the original poster will have no problems with a 120" screen.
