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

["Dr. George A. Themelis" <drt-3d@xxxxxxx>]

I have a question about screens for stereo projection.  I have a 70" Picture
King Dalite screen (this is a rugged tripod screen) and I am very happy with
it.  I use it in our stereo club and at home.  By now it is getting a bit worn
and I was thinking of buying a replacement.  If possible, I would like a larger
size, 72x96 inch seems ideal (fits the 33mm RBT mounts perfectly!)

I looked at DaLite's web site (www.dalite.com) and could not find lenticular
screens there but they carry a screen called Super Wonder-Lite.  From the
description in the web page I read:

Super Wonder-Lite
Employs a scientifically designed ridged pattern, embossed into an aluminum
vinyl and textile laminate. It's free from objectionable glare and hot spots,
even in partially darkened rooms. Not available on all screen types since the
material needs to be tensioned.  40° 1.8

I called the 800 number and I was told that this type is OK for 3d
projection.  I asked about larger sizes (the Picture King largest size in this
type of material is 70x70, even though other types come in larger sizes) and
was told that this type comes in 72 inches maximum width.  This limits the
length of the screen because the ridges must be perpendicular.  So you
could get it taller but not longer.  I asked why did the ridges have to be
perpendicular and they told me that this is how it should be.

Questions:  What do other people/clubs use?  I would like to hear some
suggestions for larger screens.

Thank you,
