Hi Ed, it hard to believe and hear you say that this projector is lacking in black level. All the reviews I read said that the black levels were superb and from the screen shots I seen the black levels look fantastic. I think that you might have a problem with your home theater setup and/or your high power screen is making the image to bright which takes away from the black level. I am not sure by having your projector 23' from the screen helps either or maybe your screen is just to big or all of the above. I just can't agree with you that the black levels are lacking. I think the black level are excellent.
I would like to quote rprice's post when he states the following:
No offense but I think that we need to look at the environment that we put these projectors in and keep in mind the type of screen and screen size, the throw distance, the color of the walls and ceiling, the video source and anything else you can think of that will affect a picture.
