Screen paint on drywall question.
6' throw distance
14' viewing distance.
the room is light controlled - shaded windows on one side
Walls are red and the ceiling is white.
I'm using Optima GT1080 projector ceiling, mounted with 140" cheap screen from Amazon. I'm thinking there are still more improvements to be made with the picture quality. I have drywall behind the screen and I would like to paint this wall as a screen. Grey or silver screen paint mix is what I'm thinking about, to avoid losing brightness. Please give me advice on paint mix formulas, if possible.
I'm from Montreal, Canada.
