2. I know a longer throw distance decreases screen brightness. Does this affect other aspects of the image?
3. Would using the maximum vertical and horizontal lens shift affect picture quality in anyway?
Min Throw or Max zoom -- highest lumen, lowest contrast
Max Throw or Min zoom -- lowest lumen, highest contrast
Going by cine4home measurement
Min Throw - 661 lumen : 19,200 contrast
Max Throw - 473 lumen : 30,900 contrast
So, make your decision there what you need most; otherwise mount it in the middle?
Lens shift affects image sharpness the most, there are users complaint of corner blur with excessive lens shift.
