Hello, new to this site. Had a question about the Epson 8700UB. I am in the process of building a home theater in my basement and just recently ordered the screen. The screen is 16:9 119" in size. I went to the Epson web site and looked under the specifications for the projector and it said "Focal Length: 22.5 - 47.2 mm, Widescreen image size (projected distance), 100" diagonal (wide: 9.8' - tele: 20.9')" Does this mean that anything over 100" in size will diminish picture quality? I will be mounted about 16-17' away. Any help would be greatly appreciated.
