Its just one more thing.
According to Projector Central, my RS2 for my screen size (58" H x 103" W) can be either 13'6" back or 11'6" close.
At 13.6 back which it is and even then my lumen's are not that great for a controlled environment. According to the throw calculator, my supposed contrast is only 20,000:1
So were saying to get 30,000:1, I would need to be 19' back. (19'/8.6=2.2) I can't recall reading this as a factor in any review. Just how close and or how far you can be.
I really thought contrast was constant from the closest to the farthest?
