I completed stretching the ALR over a frame and hung it up. Fired up the AE4000u and I was completely blown away! A stunning improvement from my previous screen, which was a painted substrate of Silver Fire. No concerns of dim image, vastly improved contrast and color vividness. It truly has to be seen to understand.
Working today, but I'll be calibrating the projector and snapping pics along the way for you over the next couple of days. Note, my above observations were with the projector unaltered in its settings.
My projector is ceiling mounted.
