Re: [photo-3d] Looking for a decent/large projection screen

[Andres Posada O <aposadao@xxxxxxxxxx>]

I have a Da-Lite Fast Fold Silver Screen, 108" by 144", I bought it from
VREX. I use it for 3D video projection. The polarization is excellent,
with imperceptible ghosting or crossover. The material has to be
tensioned onto the screen frame, and it can not be folded, so I have a
giant 115" by 10" tube in wich to carry it.
