Ok I will give info on my current set up and see what you think in terms of BW and which shade/formula:
Room 12'x 20'
walls painted dark brown, ceiling white (vaulted)
Projector about 13' from screen about 8' from floor (height)
Seating 20' (one row sofa height not elevated)
Room has 4 windows (one is covered up by pull down screen) window on right and left of screen about 4' back from screen and window "facing" screen 20' from screen. No window treatments currently but am adding lined blinds.
100% movie watching on blue ray dvd 80% night viewing with no lights on...20% during day.
88" diagonal pull down screen "dalite high power"
projector Panasonic pt-ax200u
The screen I have is from another projector/room set up and I want to change it as the viewing angles do not work well for the high power scree. I was wondering about using a BW formula and painting on the existing screen:dumbcrazy:....any one try this? Any recommendations on BW formula?
Thanks for the help
