Projector paint

 

   I have a digital projector I'll be installing in our new house.
Instead of buying a projector screen, I'd like to use some sort of paint
on the wall.

   Anyone have any experience with this?  Is there some sort of
projector paint that is better than just using plain old white wall
paint for this?

   I ask this because I have noticed that my Dad's results on an actual
projector screen look superior - looks like lots of tiny glass beads on
there - but that may in part be due to his image being half the size of
mine, since the screen he uses limits the size.

                                                 Thanks!

 




    No, it really is because of those tiny glass beads. Modern
lenticular screens ("modern" meaning post late '60's or early '70's)
redirect a greater portion of off-axis light from the projector back
toward the viewing area while, at the same time, rejecting a greater
portion of off-axis ambient light resulting in a brighter image with
greater contrast than in the movie-on-a-bedsheet/wall days. The drawback
is that to enjoy the benefits, the viewer must be more-to-less,
depending inversely on his distance from the screen, on-axis. It's that
old free lunch thing....
