My update on checking for artifacts of any kind:
I put up all the primary and secondary full color screens last night and saw no artifacts. Same thing went for scenes with fog, as some had mentioned.
I also had difficulty seeing any brightness changes where the iris may have been tripped up by subtitles on a dark background. I believe the higher speed of the AE900's iris is making it undetectable, at least to my eyes.
The only time I noticed a difference was in direct side-by-side comparison with a DLP projector (H78) in a scene where most of it was dark with a bright spot near the center. There, the dark areas were not as dark as the DLP (which was equal in many other scenes), presumably because the iris was open. Never would have known it without the comparison.
This is all being used on a 92", 1.0 gain, matte white screen (although I also used a Greywolf as well). I'm sending it a 720p feed from an Oppo DVD player over HDMI. The settings are at Picture Mode: Normal, Lamp Power: Low, NR: Off and all other settings on default except for setting white and black level. I haven't even touched any color settings yet. I'll be calibrating it later today with OpticOne and post the before and after greyscale.
