I recently bought a E-home Marquee 8500LC projector. I will install the projector on the ceiling and project an approx. 84" wide screen with a 16 X 9 format. I can control the light but for say watching sports, I like some ambient light in the room. What is a good screen material to use for my home theater? I am interested in high gain but do not want hot spotting or washed out colors. I plan on designing the screen and would consider any material (Stewart, Draper, Da-lite, Screengoo, etc.). Cost is important but a first class image is more important to me. Any help, opinions would be appreciated.
