I am a newbie and am putting together my first dedicated home theater. I built my 100" dia screen with blackout cloth and painted it with Behr Silver Screen. My projector is a Viewsonic Pro8200. I used calibration values from a review of this projector i found online and it looks great except I am getting black shadowing in dark scenes that hides any detail. I plan to paint the white ceiling black but thinking I was getting reflected light from it onto the screen, I hung black felt cloth on the ceiling out to about 8 ft and it made no difference. While my room is not "theater dark", it is pretty dark at night. If anyone has ideas on what to try, I would greatly appreciate any guidance.
